types of laptop display screens factory

Laptops come in all shapes and sizes and with dozens upon dozens of different hardware configurations, so choosing the right one for your business can be a bit tricky. After you’ve compared the size of the hard drive and the speed of the wireless network card, consider the differences in laptop display types and what you need for your company. Understanding the basics of laptop displays will help you make a smart choice.

Size Laptop displays range from the very small -- the 10-inch “netbook” computers designed primarily for surfing the Internet and basic word processing -- to the substantial -- 17-inch-or-greater screens that are the size of a desktop monitor. There are advantages to both sizes -- and the sizes in between -- but it all depends on what you need the laptop for. Bigger screens are handy for graphics-editing software and video work, whereas smaller displays make your laptop lighter and easier to place into smaller bags -- a plus for traveling.

Display Types A lot of letters get attached to a laptop display: LCD, LED, VGA, CCFL, XVGA, VGA. It’s important to keep those straight. Laptop monitors are all liquid-crystal displays (LCDs) and have two kinds of light sources – LED or CCFL. CCFL, or cold cathode fluorescent lamps, are a lighting technology used to project an image on the LCD. Light-emitting diodes (or LEDs) also emit light, but in a different way than an CCFL screen. CCFL tend to project light from a bulb in the back of the screen, whereas LEDs can be placed at intervals around the screen, making displays thinner and lighter.

Resolution In addition to the backlight technology, laptop displays are measured by their resolution -- the number of pixels they can display. Computer displays follow a rating system anchored on “VGA,” which stands for “video graphics array.” VGA displays show information at 640 by 480 pixels. XGA (extended graphics array) displays at 1024 by 768 pixels, and modern laptop displays range from WXGA (wide XGA), at 1280 by 780 pixels, through to QXGA (quantum XGA), at 2048 by 1536 pixels.

One Display or Two? In addition to the built-in display on laptops, some have a video-out option that allows you to attach a second display to your computer. When buying a laptop, consider that most laptops have a high-definition video out connector, to run your laptop to an HD TV via an HDMI cable, and a connector for a traditional computer monitor. If the work you do is best done over two screens, look for laptops with video out.

The laptops have some social display features which cannot be found in the traditional desktops. Here, one can have all type of screen sizes which can vary from the 10 inches to the 15.6 inches. So, one can buy the laptop with same specifications and with some different displays as it fits their needs. Because, it might happen that the gamer need some big displays where they can play the games while watching everything around. The students might need some medium sizes displays since they don"t need to stare at the screen for many hours; they just have their focus on the main screen. The laptop display technologies have changed very much during the past few years and now people have some new technologies which can be used by them. Following are some of the display functions and the features;

LCD: The displays in the laptop that one would mostly find are LCDs. They are the liquid crystal displays. One would find some small pieces of the liquid crystals inside then which have some certain colour. When the light passes through the display, then those colours can be seen by the user. The LCD can provide one many of the advantages when used in some portable device. The weight is very light and one can carry it very easily. Of one owns the laptop or some of the other devices, and then it is very important part of it. Also, when compared to some other options, it can have use some really less power. Also, the cost of production of these LCD is now very less. So if one is engaged in LCD manufacturing or wants to buy the LCD, it has some good news for him. The quality may vary and the highest quality can be pretty expensive as well. Also, the colour display that this LCD has is actually made of some liquid crystals.

LED: One would find the LED having some flat panel display and it uses the LED backlighting instead if the cold cathode fluorescent. These are mostly used by the LCDs. The LED is made by the semiconductors and it has some advantage, that is, that the material of the LED is really durable When the energy is passed through the LED, the liquid crystal start vibrating an emit some radiant lights that we see in the form of coloured display. One would find that the LED lights can be dimmed by applying some pulse width modulation for the supplying of current, hence the LED"s backlight can become off and it can happen very fast. If the frequency of this dimming pulse is very low or the one using the LED is pretty sensitive to the flickers, then one might experience some eye strain or the discomfort. SO, one can test this by waving his hand while being in front of the screen. One can also deduct those flickers by setting the display to its full brightness. But, this might reduce the image quality and the power consumption would be increased. Another best thing about the LED is that the screen is really clear and the images which are shown are so vibrant. Most of the gaming laptop contains LED and those people who like to work with the visuals, prefer this amazing coloured screen. LED consume more power than the LCD and they are little bit expensive than the LED. One would find the normal ranged LED for around $80. Also, LEDs do not emit too much heat so they are safe to use.

OLED: On the mobile devices, that displays that one would find of some really high quality is, the OLED. It is the organic light emitting diode. These OLED displays are the ones which use chemicals and then the light are produced which one can see. This technology is rally great for some portable devices. So, there is much space inside those portables devices which can be saved by one, with the power that is associated to it. The OLED displays are actually very beautiful. Also, one would find them pretty crisp. They are so clear and the colours emerging from it are so fascinating. For the small systems for gaming, this serves as the perfect technology since the refresh rates it has is pretty high. So if one is interested in playing games which contain some really good action, then this is the right choice for them. These LEDs also have some very low power consumption. When there is the black colour shown on the screen, one can be sure that no power is actually being used here. All the advantages are really good but the OLED has got some limitations as well. Like, this technology is emerging one and now it is only used in the portable devices. The cost of these OLED are pretty high so one would have to save up to get hands on this technology. For many people, the differences between the new versions of the LCD and the OLED aren"t that much. So, everyone actually tries to go with the option which costs less.

Plasma: plasma is actually the technology which is flat panel. It has been prevailing in the market since long time. The displays of the plasma screens are so brilliant and there are many of the displays which contain this screen. There is some limitation of this technology, that is, that this technology actually consumes lot of technology so one might avoid having this technology in the laptop which mainly runs with the batteries. The normal LCD that are being used by one, totally take around 25% of the electricity and the battery power. If one uses the plasma, then it can go too much high. Basically, many people would love having this amazing technology on their laptops especially if one is engineer. Also, they would need to re-engineer this technology if they have to work with it. There is some strong need to reduce the power drain which is done by this technology and the amount of power that is consumed by it. But the great news is that if they get successful in achieving the technology which contains some low energy consumption, then technology would be used in the mobile devices as well. Hence, one would not have to use the expensive technologies like OLED and the manufacturers would have some choice as well rather than just having the OLED technology as the best one. But still, Plasma has not been put into the laptops, especially because many of the laptops are run of the battery are there are early run on the power. If this technology comes there, then the battery would be finished soon and people would have to carry many batteries at one time.

The amazing thing that one would learn about the displays is that, these days, displays are not just used for the traditional method of showing the output generated by the computer. Also, these displays are being used as the portable antenna for the wireless connections. If one has been connected to the 802.11 network, then there is two of the antenna that would be found by one. One of those antennas is the Bluetooth antenna. If some computer has the Bluetooth device, which is located inside the computer, then it also can work as the antenna for receiving those signals of Wi-Fi. The Bluetooth antenna actually goes inside the display device and hence the display device doesn"t just stay as the display device, but it acts as some wireless network receiver. Also, someone might consider that putting the antenna might not be the good thing inside the display, but this is what makes some perfect sense. There is one thing, which is the highest point of the portable device so it is actually the very good place for the antenna to be. When the laptop is opened, it is the position which is actually at the highest point. So, the antenna wire can be run as high as one wants and one can do this himself as well. This way, one would be able to get some really good signals which would help him have the best internet speed as they want.

One should know that the computer doesn"t work on the direct current. Many of the appliances that we see in the today"s atmosphere do not work with the direct current. The reason behind this is that when we use direct current, it might happen that there is some problem with the fuse in the power supply. If that happens, then the current might flow through the wires in some big amount and it can burn up the machines. O to protect that, in computers, one would find that there is the inverter. It is located at the back of the computer so that when the electric current flows through this, the current gets converted into and alternate current and also, the inverter helps the current to flow in some steady shape. If the inverter doesn"t work so well, then it is for sure that the current flown would not be steady and there can be some serious problem that can occur to the computer. So, one should know the location of the inverter. These inverters are located at the back of the displays of the laptops. The inverter takes the power then empowers the fluorescent lights so that we can have the proper display of the computer. So, if it happens that one turns on the computer and then computer doesn"t get on, or if someone looks closely, he finds out that the LCD has some problems and if the information is being shown, it is faint, then it is surely the problem with the converter that it is not supplying the power to the backlight properly and it is not getting lit.

Backlight, is actually the light which illunminates on behind the computer screen. Everyone knows about the challenges which can be facing when buying the any of these displays. One of them is the black levels. One can get them because one would have to have some backlight which keeps shining at the end. So, having the dark colour can be really difficult specially, when it comes to have the dark black colour on the screen. So, if one is using the LCD, he would get some problems while having the colour match. Also, the LCD"s backlight is required so one can see the colours clearly. If the backlight is experiencing some problems, then one would have to take the whole deice apart and then fix that backlight that is attached behind it. Sometimes, it becomes even difficult to replace something when someone wants to get into the LCD.

Now, as one can observe, there are many of the components of the laptop. They all have some various types and each of the types have some characteristics. So, one can learn about these types to use this data for the practical implementation. Like, as one knows that the plasma displays can have lots of the consumption of the electricity, then he would avoid that display. Also, if one knows about the advantages of the LED, and knows that it is safe to sue, then one would surely go for the LED and buy the computers which have the LED screen so that the image that appear on the computer become really bright. Also, with the help of knowing that antenna is actually in the display of the laptop, one can be assure of the fact that he is having the antenna at the best position and he is going to catch the maximum signals. Another thing is that one can know about the importance of the back light. One can know that how the backlights can be used and when one turns on the commuter and sees some really dim display, he can know that it is sue to the backlight. Hence he can repair that himself or can take to the laptop repair shop.

After choosing what CPU, GPU, RAM, and storage you need in a laptop, sometimes the next in line is its display. Now, depending on what you’ll use it for (maybe competitive gaming, maybe content creation or maybe even both), there are a lot of factors to be considered. We know most of you have already come across terms like refresh rate or response time, or TN panels, some may have even asked the question “What in the world is G-sync?” Well today, we’ll answer those questions for you in our Laptop Display 101: Display Types guide. Alright then, let’s go find that display you need.

Let’s discuss the most commonly known factor in choosing a display, its display type. Similar to mobile phones, laptops are also equipped with different kinds of panels, though they have fewer options. There are currently three display types available for laptops, and the third one only recently popped up in the market — Twisted Nematic (TN), In-Plane Switching (IPS),and Organic Light-emitting Diode (OLED). Each of these panels have their own advantages and disadvantages.

Before we continue, let’s get this out of the way first; there is no clear “best display type” among the three, as each cater to different needs and audiences.

Let’s also be clear with a few terms, namely Response Times, Refresh Rates, and G-Sync. Response times dictate the speed in which a pixel can display a change from either black to white, or from one shade of gray to another. It is often confused with input lag, which is the measurement of how fast a peripheral’s input, say a mouse or a keyboard, registers on the display.

Response time affects visuals on a display more, and is especially important when there is something fast happening on the screen. Response times also affect whether or not a display experiences “ghosting”, a phenomenon where trails of a moving object become visible on the screen because the pixels took to long to shift. This happens more often with longer response time displays.

Refresh rate, on the other hand, is the number of times per second that the screen refreshes the image on it. Refresh rates are different than frame rates, which is a famous method of measurement in benchmarking the performance of devices. That is because refresh rate actually dictates the maximum frame rate a screen can display, which is why it’s better to have higher refresh rates when using powerful devices. For example, if you’re averaging >100fps but the display’s refresh rate is only 60Hz, then all you’re actually seeing is 60fps.

Lastly, G-Sync, Nvidia’s proprietary display technology. G-sync synchronizes the refresh rate of your display to the framerate of your Nvidia graphics card or chip. This is done to eliminate visual artifacts, screen tearing, input lag, and stuttering. The end result is smoother gameplay and visuals. The counterpart to this on AMD’s side is Freesync technology, which pretty much does the same thing except for Radeon cards and Freesync supported displays. Although, FreeSync is not yet available on laptops.

First up, is Twisted Nematic or more commonly known as TN. TN panels are actually the oldest of the three display types, as they have been widely used since the 1980’s and were even considered as a technological breakthrough in display technology during its early development. Of course, today it now has fierce competition from other display types, but it still remains as one of the most widely used panels for laptops, especially in the entry-level and budget segment.

The main reason why TN panels are so famous is that they are cheaper to manufacture than the two other types. There are more expensive TN panels on the market though, and these are the high-quality ones that are mainly used in some high-end laptops and gaming monitors. It is also widely regarded in the gaming community and is one of the go-to panel types for professional and competitive gaming. That is because TN panels can have high refresh rates and low response times at a much lower price compared to IPS and OLED.

While TN panels are great for competitive and professional gaming, it’s generally not good for content creation, media consumption or even on some games like RPGs or Adventure games, which have vivid sceneries. This is because TN panels have poor viewing angles and bad color reproduction and accuracy. There are high-quality TN panels with excellent color reproduction and accuracy and overall better viewing angles, but they still can’t compete with the likes of IPS or OLED in these regards. Not to mention, they will cost an arm and a leg.

Okay next up, is In-Plane Switching or more commonly known as IPS. There was a need to address the underlying issues with TN panels, namely their poor viewing angles and subpar color reproduction and accuracy.  So, what developers came up with was IPS, a panel that can maintain all-around good viewing angles and consistently provide excellent color reproduction and accuracy. The drawbacks were that response times became longer and refresh rates got capped at a certain point (60Hz max). Only recently did IPS panels with >60Hz refresh rates start to pop up. Apart from that, these panels are also more expensive to manufacture than TN, which is why most laptops with IPS displays are in the upper-mid range to high-end category.

IPS panels are a good fit for content creation and media consumption due to their improved viewing angles, color reproduction, and accuracy. They also offer a good gameplay experience for games that take advantage of better colors such as RPGs and Adventure games. Although, they are no longer much of a choice for competitive and professional gamers due to their slower response times and lower refresh rates. There are IPS panels on the market now with higher refresh rates but, like high-quality TN panels, these cost an arm and a leg.

Organic Light-emitting Diode or OLED for short is a type of display that has been available on the market for quite some time already. It has been more utilized in TVs and mobile phones rather than in mobile PCs. It has only recently made its way into the laptop market. OLED displays are like IPS panels, but on steroids. This means that they have even better color reproduction and accuracy while maintaining good viewing angles. Blacks are also more vivid on OLED displays more than on any other kind of panel.

The downsides to OLED displays is that they draw more power and are prone to display burn-in. Burn-in is when an image, shown for prolonged periods of time, remains on the screen despite no longer being displayed. A good example of this is the Windows taskbar — when burn-ins occur in a display, the taskbar will remain on the screen despite shifting to other tasks like watching movies or playing games. Although this happens less frequently now due to incremental improvement, the risks of it happening are still there, so do operate OLED displays with care.

Just like with IPS panels, OLED displays are perfect for content creators, movie lovers, and those who enjoy playing games that do not require fast response times. Still, the biggest caveat is that OLED displays are even much more expensive than IPS.

Then we have OLED displays, which is essentially IPS on steroids, but carries the risk of burn-in, and is more power-hungry. Devices with these panels are the most expensive of the bunch, so these are only for consumers with very deep pockets.

We have created guides for gaming laptops and editing laptops should you require deeper information in choosing a device. Since there are no major updates in hardware just yet, these guides can still be considered relevant:

Liquid crystal displays more or less fall into three categories based on their manufacturer and the driving force behind the liquid crystal. All have their own strengths and weaknesses. Twisted nematic, or TN as it’s often called, is an older display technology. Later, In-Plane Switching, or IPS displays, were developed to combat some of the problems with TN, and a third major technology is the Vertical Aligned, or VA panel.

All LCDs are pretty much built the same, with a backlight, two polarizers, the liquid crystal, and the thin-film transistor which provides the current to the individual pixels. The major difference between the three display types is how the liquid crystal is used to block the backlight for each subpixel.

Generally, laptop displays refresh the image sixty times per second, or at 60 Hertz. Some gaming laptops offer refresh rates at 144 Hz or more, which provide a smoother experience, and both AMD and NVIDIA support variable refresh rates as well. The maximum refresh rate is impacted by the design of the LCD, and the various designs all have different limits and response times.

Twisted nematic, or TN, is the earliest LCD design that’s still used in laptop displays. As the name suggests, the liquid crystal actually twists to allow light through. The design is very simple, with only a single transistor required to drive the process, and therefore it’s the least expensive display to manufacture as well. In addition to it being the lowest cost, it also can operate very quickly, so the TN display is still the panel of choice for many gamers because the panels can hit the high refresh rates like 144 Hz.

While cost and speed are definite advantages of TN, they suffer from quite severe off-angle color shift and are really only usable when viewed directly. Large TN panels can exhibit the color shift even when viewed directly, because of the increasing angle of viewing (relative to the user) as the panel gets further from the center. Even when viewed directly, TN panels offer poor color accuracy as well. Due to these limitations, TN displays have fallen out of favor for most laptops, although they are still regrettably found in some budget devices, and gaming laptops where the higher refresh rate is of more importance than color reproduction.

In-plane switching, or IPS, was developed to provide solutions to the off-angle viewing issues that plague TN displays. The liquid crystal rotates horizontally rather than twisting like a spring in TN, allowing more light through the further it’s rotated, which in turn varies with the amount of voltage applied. This process requires two transistors per subpixel though, which drives up the manufacturing cost. IPS displays are not as quick to operate as a TN one would be either, so driving them to very high refresh rates is difficult. But, this design does offer excellent off-angle viewing, as well as very accurate color reproduction.

And while IPS is a significant step up in quality over TN, it does have some limitations of its own. In particular, it can’t produce the highest contrast ratios, especially compared to Vertical Aligned panels that we’ll look at next. But IPS displays offer the widest viewing angle of any display technology, and keep their color accuracy intact even when viewed at an angle. This makes them ideal for laptops and tablets, and pretty much all quality laptops utilize IPS displays at this point, although this really only started in earnest in the last several years.

Although IPS is the generic class, several manufacturers have created their own version of IPS, such as Samsung’s Plane to Line Switching (PLS) or AU Optronics with their Advanced Hyper-Viewing Angle (AHVA) technology, which by the acronym sounds like it is a VA panel, but it’s actually an IPS design.

The final display LCD display technology that is prevalent in the industry is the vertical alignment, or VA, panel. VA aligns the liquid crystal vertically when no voltage is applied, and with voltage, the crystals shift to the horizontal plane. This mechanism does have some drawbacks to viewing angles, but to counteract this, most VA panels use multi-domain vertical alignment (MVA) with the crystals rotating in different directions.

The biggest advantage of VA displays is their contrast ratio capabilities, and modern VA panels can achieve 3000:1 or more contrast. With MVA technology the off-angle viewing is also much better than TN displays, although not as good as IPS displays, and where an IPS display can achieve 178° viewing angles on both the horizontal and vertical planes, a VA panel is going to be around 160° or so depending on the exact type of panel.

VA panels can be found in some computer monitors, but most laptops utilize IPS because the strengths are more suitable to a portable device. VA is still widely used in televisions though, since you generally don’t view them at a very oblique angle, and the increased contrast ratio provides better black levels for movies.

The final display technology that is available in laptops is organic light emitting diode, or OLED. Unlike all the LCD displays, OLED doesn’t require a backlight because the individual subpixels emit light. Because of this, OLED displays offer practically infinite contrast ratio, since the brightness of each subpixel can be varied on a subpixel-by-subpixel basis, and subpixels can be turned off completely.

OLED displays have been used quite a bit in smartphones, and you can even buy OLED televisions, but the technology has not been utilized very much in the PC space.

Although OLED displays offer a lot of advantages over LCD displays, OLED with an RGB (Red Green Blue) matrix of subpixels (aka RGB OLED) is quite expensive to build, especially on a larger panel. The amazing contrast and accurate color reproduction is a benefit, but the cost can be prohibitive. OLED also doesn’t use any power to display a black screen, but to get high brightness levels on a large panel showing a white image can use substantially more energy than a comparable LCD.

Besides price, the other notable drawback to OLED is that the nature of the technology can limit the longevity of the display. As the subpixels are used to create light in either red, green, or blue, the subpixels themselves age and will dim over time. The different colors also age at different rates – with blue being the fastest to go – and to compensate, the subpixels may not be arranged in a true RGB pattern which can reduce the effective resolution of the device. Because of the different rates, there’s also a chance of burn-in if a static image is left on the display for a long period of time, a problem which in turn can be mitigated, though not entirely.

Currently televisions that use OLED are almost exclusively built on a different technology than what you’d see in smartphones and laptops. Right now, LG owns the OLED TV market and produces panels for everyone else using WOLED, which is a white OLED subpixel that is paired with color filters to convert said subpixels to red, green, or blue subpixels. This allows the panels to be manufactured for a cost that people can actually afford, and partially mitigates burn-in since all subpixels have a similar life-expectancy curve. However WOLED subpixels will still age faster or slower depending on how heavily they"re used, so burn-in can still be an issue.

Samsung is reportedly looking into something similar, but will use a blue OLED as the base and quantum dots as the filter/converter. But neither of these technologies are used in laptops at the moment, so when you see an OLED TV for several thousand, and wonder why an OLED PC monitor is double the cost for a quarter the size, just know that all things are not created equally.

Due to the cost, high power usage, and aging issues, OLED is currently not ideal for use in laptops, and although it can be stunning to see in a laptop, it does have its drawbacks.

Accurate to the T. Unlike gamers, content creators have more stringent requirements for an ideal laptop display. In this article, we will look into several factors that determine an ideal LCD panel for a content creator or workstation laptop, including factors such as pixel density, color gamuts, color accuracy, and more. We take the implementation of LCD displays in high-end MSI content creation laptops as examples to explain the basics. (Sponsored article.)

In our previous article on laptop displays for gamers, we"ve seen some of the important aspects that govern LCD panel choice and performance. This article aims to be an extension of that and will focus on some critical factors that professional users would look into while purchasing a workstation laptop.

Unlike gamers who can make do with fairly decent color accuracy and color-gamut coverage, creative pros require these parameters to be the best they can get. Working with high-resolution images and video for critical projects demands not only the required processing horsepower but also a capable display that is as true to real life as possible.

In this article, we will take a look at how some of these parameters such as pixel density, color gamut, color calibration, and color accuracy are factored in while deciding on a laptop display for content creators. We illustrate how these parameters are factored-in during the creation of premium MSI notebooks for content creators.

Pixel density, also known as pixels per inch (PPI), refers to the number of pixels per square inch of the display. The higher the pixel density, the more information can be displayed on the screen. Pixel density also correlates with the resolution of the display. For example, the pixel density of a 15.6-inch FHD display comes to around 141 while a UHD display on the same screen size yields 282.4 pixels per inch. Therefore, many more pixels can be accommodated in case of the UHD display on the same screen area, resulting in much more detail, sharper fonts, smoother lines, and overall a greatly enhanced viewing experience.

There is a point to note here, though. While higher pixel densities are generally welcome, the numbers don"t matter beyond a certain threshold. This is because the human eye cannot distinguish more than 400 pixels per inch at a distance of about 16 inches from the monitor.

In our previous article, we gave an introduction to the concept of color gamut. Basically, color gamut specifies the range of colors that the display can show in comparison to the colors perceived by the human eye. Displays with wider color gamuts are of utmost importance to content creators, especially those who work on photography and color-sensitive video-editing.

Commonly used standards include sRGB, NTSC, and AdobeRGB.Most LCD panels in the market list out the color gamut standards they adhere to and the extent of coverage. Professionals tend to look at the AdobeRGB coverage as it allows for more vivid colors than what sRGB can. There can be a lot of variation in color gamuts, so a standardized system helps to determine if the LCD monitor is displaying the colors it should.

The graph on the right is what is referred to as the xy chromaticity diagram established by the International Commission on Illumination (CIE). In the graph, the color perception of the human eye is represented by the inverted U-shaped area and individual color gamut standards are denoted by triangles. The larger the size of each triangle, the wider is the color coverage of the panel for that particular standard. The panel cannot display colors outside the corresponding triangle"s area.

sRGB is the commonly used color gamut standard across LCD monitors, printers, and most digital cameras. However, the overall color range of sRGB is very limited and does not include highly saturated colors. Adobe RGB overcomes this limitation, and panels supporting this color gamut standard can display a much more vivid color profile, especially when considering the greens. The image below illustrates this nicely.

With this information in mind, let us have a look at the color-gamut coverage of a high-end MSI content creator laptop. We see that the laptop"s display can cover nearly 100% of both the sRGB and the AdobeRGB color standards. This is an excellent color reproduction for a content creation notebook. MSI equips most of its laptops with True Color technology from Portrait Displays Inc. to ensure color gamut reproduction as close as possible to 100% sRGB or 100% AdobeRGB.

MSI first introduced True Color technology in 2014 and continues to use it across its portfolio. The process starts right from inspecting the panels coming from the factory. Each panel is color calibrated, which includes setting the ideal color temperature, color gamut, and grayscale values. These are then calibrated and adjusted using a color profile suited for the monitor before shipping.

True Color encompasses a suite of features that offer users a lot of control in fine-tuning the color profile. With True Color, users can share color profiles, adjust color temperature, and sync their settings across supported displays.

Delta E is a measure of the color difference that can be perceived by a human eye. In general, a Delta E value of 1 implies that two colors can be just about differentiated by the human eye while a Delta E of 0 implies that the colors are mathematically the same. Delta E values less than 2 are imperceptible due to limitations in human eyesight.Those requiring accurate color reproduction look out for the Delta E value that is calibrated at the factory. While content creator laptop displays generally have very low Delta E, depending on the display type, it is also possible to furthercalibrate the display and reduce the Delta E to less than 1.0. LCD panels with lower Delta E values display more accurate colors that are true-to-life as possible.

CalMAN is a popular tool used for color calibration across various industries. CalMAN offers hardware support for most modern LCD panels and is a valuable tool across the production chain right from post production to broadcasting. While MSI"s True Color technology helps in getting a color-accurate display right from the first step of display production, the "CalMAN Verified" branding assures customers in knowing that they are really getting their money"s worth. "CalMAN Verified" displays add an extra layer of assurance for both content creation and consumption. High-end MSI content creation laptops with a 4K panel carry this branding to assure creative pros that they are getting a highly color-accurate display. Whether editing a beautiful landscape photo, color-grading film footage, or even immersive entertainment, MSI laptops with "CalMAN Verified" displays offer a great true-to-life viewing experience.

In this article, we have provided a brief overview into what goes into some of the important criteria concerning selection of LCD panels for content creation notebooks. While you do have specialized monitors for professionals, a color-accurate laptop display is an indispensable tool for those on the go.

MSI content creation laptops such as the Prestige 14 and Prestige 15 offer a "True Pixel" display experience that combines a high resolution (4K), high density (>220 PPI) display with nearly 100% AdobeRGB coverage and impeccable color accuracy guaranteed by MSI"s True Color technology and "CalMAN Verified" branding so you know you are getting the absolute best canvas for unhindered creativity.

As always, we make sure to incorporate extensive display testing in our reviews so that you can make an informed purchase. We even offer calibrated color profiles that can be freely downloaded from our corresponding review pages.

We hope this primer on LCD panel selection for content creators was helpful in offering a high-level know-how into this important aspect of laptop purchase. Watch this space for more upcoming laptop 101 articles, including touchpad design and more.

Besides this careful component matching it’s ensured that the latest GeForce RTX Turing graphics are at the centre of MSI laptops. Whether playing blockbuster games like Battlefield V with ray tracing for the very best image quality or working with creative apps like Autodesk 3DS Max, Adobe Premiere Pro and Lightroom or DaVinci Resolve, RTX Laptops are true "workhorses" for professionals, students, and gamers alike. They are perfect for combining leisure and work.

I am one of the founders of Notebookcheck, which I dedicated myself with after my studies at the Vienna Technical University were completed. Computers have been an integral part of my daily activities since the time of the Commodore C64 and Atari 1040ST. Besides new technologies such as electric mobility and environmental technology, I am also interested in architecture and construction engineering.

Commonly found in high-definition high-end laptops or high-class OLED TVs, and not belonging to the LCD category (TN, VA, and IPS), an AMOLED screen with an active light-emitting panel is able to display the most vivid colors. AMOLED panels not only wield 10-bit color and over 1.07 billion colors, they are also certified as VESA DisplayHDR True Black, allowing for up to 100X deeper black levels and a greater dynamic range. The proportion of harmful blue light is 60% lower than that of ordinary LCD screens. In addition to having the response time of fewer than 0.5 milliseconds, it has the widest viewing angle compared to all previously mentioned display panels. There will be no difference in color from different viewing angles. Generally speaking, AMOLED screens are only used in high-end TVs. GIGABYTE’s AERO 15 OLED is the ever first laptop to adopt an AMOLED screen display.

There are two basic technologies used in LCD panels for laptops: TN and IPS. TN panels are the most common, as these are the least expensive and tend to offer faster refresh rates. TN panels have some disadvantages, including narrow viewing angles and colors. TN panels offer less overall color, but this typically only matters for graphics designers.

IPS offers higher color and viewing angles. However, these screens tend to cost more, have slower refresh rates, and are not as suited for gaming or fast video.

IGZO is a new chemical composition for building displays that replaces the traditional silica substrate. The technology allows for thinner display panels with lower power consumption. IGZO will eventually be a major benefit for portable computing, especially as a way to combat the extra power consumption that comes with higher-resolution displays.

OLED is another technology showing up in some laptops. It has been used for high-end mobile devices such as smartphones for some time. The primary difference between OLED and LCD technologies is that OLED doesn"t require a backlight. Instead, pixels generate light from the display, which gives these screens better overall contrast ratios and color.

Touchscreens are becoming a major feature of many Windows-based laptops. This technology replaces the trackpad for navigating the operating system. Touchscreens generally add to a laptop"s cost and draw more power, meaning these laptops have less running time on batteries than a non-touchscreen laptop.

Some touchscreen laptops come with a display that can be folded or spun around, offering a tablet-style experience. These are often referred to as convertible or hybrid laptops. Intel"s marketing refers to such machines as 2-in-1 designs. The important thing to consider with these types of laptops is the ease of use when in tablet mode, based on screen size. Often, the smallest screens, such as 11-inch screens, work best for these designs, but some companies offer them up to 15 inches, making the device more difficult to hold and use.

Most consumer laptops tend to use glossy coatings over LCD panels, letting more color and brightness come through to the viewer. The downside is that these screens are difficult to use with certain types of lighting, such as outdoor lighting, without producing a large amount of glare. These look great in home environments where it is easier to control glare. Most display panels that feature a touchscreen use a form of glossy coating.

While most consumer laptops feature glossy coatings, corporate-style laptops generally feature anti-glare or matte coatings. These coatings reduce the amount of external light reflecting on the screen, making these laptops better for office lighting or outdoors. The downside is that the contrast and brightness tend to be muted on these displays.

In the past, graphics processors weren"t much of an issue for consumer laptops. The majority of users didn"t do much graphically that required 3D graphics or accelerated video. This has changed as more people use their laptops as their primary computers.

Recent advancements in integrated graphics have made it less necessary to have a dedicated graphics processor, but these can still be beneficial. A dedicated graphics processor is helpful for 3D graphics (gaming or multimedia) or accelerating non-gaming applications, such as Photoshop. Integrated graphics also offer improved performance, such as the Intel HD Graphics, which supports Quick Sync Video for accelerated media encoding.

AMD and NVIDIA have technologies that can allow certain graphics processors to run in pairs for additional performance. AMD"s technology is referred to as CrossFire, and NVIDIA"s is SLI. While the performance is increased, battery life for such laptops is reduced due to the extra power consumption.

Just like televisions, laptop displays start to flicker too after a few years. You may sometimes also notice the display turning blank even when the laptop is on. Alternatively, you might find some white lines running down the display.

This doesn’t necessarily mean that there is an issue with the motherboard. If your laptop keeps turning off every few minutes and doesn’t turn on, there is a high chance that the AC adapter has malfunctioned. You can get help from a professional to confirm and get the AC adapter replaced, if required. There is also a possibility that the DC power jack may have broken. A DC connector (or DC plug) is an electrical connector that supplies steady power to the device.

If the DC jack has broken, you can try adjusting the plug’s angle in its jack. If you see some lights turning on but the device is still not booting, it’s time to replace the DC jack. If that doesn’t help, it’s a clear indication of a motherboard-related issue. You can either get the motherboard repaired or replaced by the brand service center. Getting the motherboard repaired could cost you anywhere up to Rs 10,000, whereas the cost of replacing the motherboard can go anywhere up to Rs 25,000.

If you ever notice multi-coloured or single-coloured vertical lines on your laptop screen, it may be a result of a hardware failure or due to damage to the screen. To try fixing it yourself, first unplug your laptop, hold the power button for 30 seconds and restart the laptop. If you continue to see coloured lines, the issue is probably with the LCD screen, which will need to be replaced from the brand’s service center. To be sure about the LCD screen problem, try connecting your laptop to another monitor and see if the issue persists. If it does, the issue is certainly in the LCD panel.

On turning on the laptop when you see the lights blinking and hear the fan working but if the laptop screen is blank and doesn’t display anything, this is again an indication of a faulty motherboard. The first thing to do is to transfer all the data to another drive to make sure your data is safe. Before going ahead and getting the motherboard repaired or replaced, you could try performing a hard reset (also known as a factory reset), which can mostly help in resolving the blank display issue.

Firstly, check if your laptop’s brightness level is set to maximum. If the display is still dim, try restarting the device. This could just be a system error that can be resolved by restarting the device. Also, check if the AC adapter cord is loose and firmly connect it to the outlet and laptop. If the issue still persists, it is mostly due to a failure of the LCD. Behind the LCD, there is an inverter board and backlight bulb which control the picture.

The inverter board converts the low voltage your laptop uses, into higher voltage required by the long bulb that lights up the LCD screen. If the inverter board or bulb fail, you will experience the problem of a dimmed display. Even if one of these two components fail, the screen will need to be replaced, unless the service center can help by just replacing the bulb. We wouldn’t recommend you try resolving it yourself, as this is more complex and you could end up damaging the circuit board and the backlight lamp. So, it’s best to leave this job to an expert.

Laptops are fragile and can easily break, especially with more and more thinner and lighter models being launched now. Some of the most common ways how a laptop is damaged include: when it accidentally falls and the screen cracks, when it’s held at an awkward angle or if you unknowingly placed something heavy on the laptop. Remember, a cracked laptop screen can affect the overall functioning of the device in some cases.

Since brands do not cover the laptop screen, it’s best to get your device covered with a protection plan in advance. Screen replacements are expensive and can cost you anywhere up to Rs. 15,000 but if you have the

A liquid-crystal display (LCD) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers. Liquid crystals do not emit light directlybacklight or reflector to produce images in color or monochrome.seven-segment displays, as in a digital clock, are all good examples of devices with these displays. They use the same basic technology, except that arbitrary images are made from a matrix of small pixels, while other displays have larger elements. LCDs can either be normally on (positive) or off (negative), depending on the polarizer arrangement. For example, a character positive LCD with a backlight will have black lettering on a background that is the color of the backlight, and a character negative LCD will have a black background with the letters being of the same color as the backlight. Optical filters are added to white on blue LCDs to give them their characteristic appearance.

LCDs are used in a wide range of applications, including LCD televisions, computer monitors, instrument panels, aircraft cockpit displays, and indoor and outdoor signage. Small LCD screens are common in LCD projectors and portable consumer devices such as digital cameras, watches, digital clocks, calculators, and mobile telephones, including smartphones. LCD screens are also used on consumer electronics products such as DVD players, video game devices and clocks. LCD screens have replaced heavy, bulky cathode-ray tube (CRT) displays in nearly all applications. LCD screens are available in a wider range of screen sizes than CRT and plasma displays, with LCD screens available in sizes ranging from tiny digital watches to very large television receivers. LCDs are slowly being replaced by OLEDs, which can be easily made into different shapes, and have a lower response time, wider color gamut, virtually infinite color contrast and viewing angles, lower weight for a given display size and a slimmer profile (because OLEDs use a single glass or plastic panel whereas LCDs use two glass panels; the thickness of the panels increases with size but the increase is more noticeable on LCDs) and potentially lower power consumption (as the display is only "on" where needed and there is no backlight). OLEDs, however, are more expensive for a given display size due to the very expensive electroluminescent materials or phosphors that they use. Also due to the use of phosphors, OLEDs suffer from screen burn-in and there is currently no way to recycle OLED displays, whereas LCD panels can be recycled, although the technology required to recycle LCDs is not yet widespread. Attempts to maintain the competitiveness of LCDs are quantum dot displays, marketed as SUHD, QLED or Triluminos, which are displays with blue LED backlighting and a Quantum-dot enhancement film (QDEF) that converts part of the blue light into red and green, offering similar performance to an OLED display at a lower price, but the quantum dot layer that gives these displays their characteristics can not yet be recycled.

Since LCD screens do not use phosphors, they rarely suffer image burn-in when a static image is displayed on a screen for a long time, e.g., the table frame for an airline flight schedule on an indoor sign. LCDs are, however, susceptible to image persistence.battery-powered electronic equipment more efficiently than a CRT can be. By 2008, annual sales of televisions with LCD screens exceeded sales of CRT units worldwide, and the CRT became obsolete for most purposes.

Each pixel of an LCD typically consists of a layer of molecules aligned between two transparent electrodes, often made of Indium-Tin oxide (ITO) and two polarizing filters (parallel and perpendicular polarizers), the axes of transmission of which are (in most of the cases) perpendicular to each other. Without the liquid crystal between the polarizing filters, light passing through the first filter would be blocked by the second (crossed) polarizer. Before an electric field is applied, the orientation of the liquid-crystal molecules is determined by the alignment at the surfaces of electrodes. In a twisted nematic (TN) device, the surface alignment directions at the two electrodes are perpendicular to each other, and so the molecules arrange themselves in a helical structure, or twist. This induces the rotation of the polarization of the incident light, and the device appears gray. If the applied voltage is large enough, the liquid crystal molecules in the center of the layer are almost completely untwisted and the polarization of the incident light is not rotated as it passes through the liquid crystal layer. This light will then be mainly polarized perpendicular to the second filter, and thus be blocked and the pixel will appear black. By controlling the voltage applied across the liquid crystal layer in each pixel, light can be allowed to pass through in varying amounts thus constituting different levels of gray.

The chemical formula of the liquid crystals used in LCDs may vary. Formulas may be patented.Sharp Corporation. The patent that covered that specific mixture expired.

The optical effect of a TN device in the voltage-on state is far less dependent on variations in the device thickness than that in the voltage-off state. Because of this, TN displays with low information content and no backlighting are usually operated between crossed polarizers such that they appear bright with no voltage (the eye is much more sensitive to variations in the dark state than the bright state). As most of 2010-era LCDs are used in television sets, monitors and smartphones, they have high-resolution matrix arrays of pixels to display arbitrary images using backlighting with a dark background. When no image is displayed, different arrangements are used. For this purpose, TN LCDs are operated between parallel polarizers, whereas IPS LCDs feature crossed polarizers. In many applications IPS LCDs have replaced TN LCDs, particularly in smartphones. Both the liquid crystal material and the alignment layer material contain ionic compounds. If an electric field of one particular polarity is applied for a long period of time, this ionic material is attracted to the surfaces and degrades the device performance. This is avoided either by applying an alternating current or by reversing the polarity of the electric field as the device is addressed (the response of the liquid crystal layer is identical, regardless of the polarity of the applied field).

Displays for a small number of individual digits or fixed symbols (as in digital watches and pocket calculators) can be implemented with independent electrodes for each segment.alphanumeric or variable graphics displays are usually implemented with pixels arranged as a matrix consisting of electrically connected rows on one side of the LC layer and columns on the other side, which makes it possible to address each pixel at the intersections. The general method of matrix addressing consists of sequentially addressing one side of the matrix, for example by selecting the rows one-by-one and applying the picture information on the other side at the columns row-by-row. For details on the various matrix addressing schemes see passive-matrix and active-matrix addressed LCDs.

LCDs, along with OLED displays, are manufactured in cleanrooms borrowing techniques from semiconductor manufacturing and using large sheets of glass whose size has increased over time. Several displays are manufactured at the same time, and then cut from the sheet of glass, also known as the mother glass or LCD glass substrate. The increase in size allows more displays or larger displays to be made, just like with increasing wafer sizes in semiconductor manufacturing. The glass sizes are as follows:

The origins and the complex history of liquid-crystal displays from the perspective of an insider during the early days were described by Joseph A. Castellano in Liquid Gold: The Story of Liquid Crystal Displays and the Creation of an Industry.IEEE History Center.Peter J. Wild, can be found at the Engineering and Technology History Wiki.

In 1888,Friedrich Reinitzer (1858–1927) discovered the liquid crystalline nature of cholesterol extracted from carrots (that is, two melting points and generation of colors) and published his findings at a meeting of the Vienna Chemical Society on May 3, 1888 (F. Reinitzer: Beiträge zur Kenntniss des Cholesterins, Monatshefte für Chemie (Wien) 9, 421–441 (1888)).Otto Lehmann published his work "Flüssige Kristalle" (Liquid Crystals). In 1911, Charles Mauguin first experimented with liquid crystals confined between plates in thin layers.

In 1922, Georges Friedel described the structure and properties of liquid crystals and classified them in three types (nematics, smectics and cholesterics). In 1927, Vsevolod Frederiks devised the electrically switched light valve, called the Fréedericksz transition, the essential effect of all LCD technology. In 1936, the Marconi Wireless Telegraph company patented the first practical application of the technology, "The Liquid Crystal Light Valve". In 1962, the first major English language publication Molecular Structure and Properties of Liquid Crystals was published by Dr. George W. Gray.RCA found that liquid crystals had some interesting electro-optic characteristics and he realized an electro-optical effect by generating stripe-patterns in a thin layer of liquid crystal material by the application of a voltage. This effect is based on an electro-hydrodynamic instability forming what are now called "Williams domains" inside the liquid crystal.

In 1964, George H. Heilmeier, then working at the RCA laboratories on the effect discovered by Williams achieved the switching of colors by field-induced realignment of dichroic dyes in a homeotropically oriented liquid crystal. Practical problems with this new electro-optical effect made Heilmeier continue to work on scattering effects in liquid crystals and finally the achievement of the first operational liquid-crystal display based on what he called the George H. Heilmeier was inducted in the National Inventors Hall of FameIEEE Milestone.

In the late 1960s, pioneering work on liquid crystals was undertaken by the UK"s Royal Radar Establishment at Malvern, England. The team at RRE supported ongoing work by George William Gray and his team at the University of Hull who ultimately discovered the cyanobiphenyl liquid crystals, which had correct stability and temperature properties for application in LCDs.

The idea of a TFT-based liquid-crystal display (LCD) was conceived by Bernard Lechner of RCA Laboratories in 1968.dynamic scattering mode (DSM) LCD that used standard discrete MOSFETs.

On December 4, 1970, the twisted nematic field effect (TN) in liquid crystals was filed for patent by Hoffmann-LaRoche in Switzerland, (Swiss patent No. 532 261) with Wolfgang Helfrich and Martin Schadt (then working for the Central Research Laboratories) listed as inventors.Brown, Boveri & Cie, its joint venture partner at that time, which produced TN displays for wristwatches and other applications during the 1970s for the international markets including the Japanese electronics industry, which soon produced the first digital quartz wristwatches with TN-LCDs and numerous other products. James Fergason, while working with Sardari Arora and Alfred Saupe at Kent State University Liquid Crystal Institute, filed an identical patent in the United States on April 22, 1971.ILIXCO (now LXD Incorporated), produced LCDs based on the TN-effect, which soon superseded the poor-quality DSM types due to improvements of lower operating voltages and lower power consumption. Tetsuro Hama and Izuhiko Nishimura of Seiko received a US patent dated February 1971, for an electronic wristwatch incorporating a TN-LCD.

In 1972, the concept of the active-matrix thin-film transistor (TFT) liquid-crystal display panel was prototyped in the United States by T. Peter Brody"s team at Westinghouse, in Pittsburgh, Pennsylvania.Westinghouse Research Laboratories demonstrated the first thin-film-transistor liquid-crystal display (TFT LCD).high-resolution and high-quality electronic visual display devices use TFT-based active matrix displays.active-matrix liquid-crystal display (AM LCD) in 1974, and then Brody coined the term "active matrix" in 1975.

In 1972 North American Rockwell Microelectronics Corp introduced the use of DSM LCDs for calculators for marketing by Lloyds Electronics Inc, though these required an internal light source for illumination.Sharp Corporation followed with DSM LCDs for pocket-sized calculators in 1973Seiko and its first 6-digit TN-LCD quartz wristwatch, and Casio"s "Casiotron". Color LCDs based on Guest-Host interaction were invented by a team at RCA in 1968.TFT LCDs similar to the prototypes developed
