First, the display screen on a sunlight readable/outdoor readable LCD should be bright enough so that the display is visible under strong sunlight. Second, the display contrast ratio must be maintained at 5 to 1 or higher.

Although a display with less than 500 nits screen brightness and a mere 2 to 1 contrast ratio can be read in outdoor environments, the quality of the display will be extremely poor. At i-Tech, a truly sunlight readable display is typically considered to be an LCD with 1000 nits or greater screen brightness with a contrast ratio greater than 5 to 1. In outdoor environments under the shade, such a display can provide an excellent image quality.

Luminance is a major determinant of perceived picture quality in an LCD. The importance of luminance is enhanced by the fact that the human mind will react more positively to brightly illuminated scenes and objects. Users are typically more drawn to brighter displays that are more pleasing to the eye and easier to read. In indoor environments, a standard active-matrix LCD with a screen luminance around 250 nits looks good. However, a sunlight readable LCD with a screen luminance of 1,000 will look even more beautiful.

Contrast ratio (CR) is the ratio of luminance between the brightest �white� and the darkest �black� that can be produced on a display. CR is another major determinant of perceived picture quality. If a picture has high CR, you will judge it to be sharper and more crisp than a picture with lower CR. For example, a typical newspaper picture has a CR of about 5 to 7, whereas a high quality magazine picture has a CR that is greater than 15. Therefore, the magazine picture will look better even if the resolution is the same as that of the newspaper picture.

A typical AMLCD exhibits a CR between 300 to 700 when measured in a dark room. However, the CR on the same unit measured under ambient illumination is drastically lowered due to surface reflection (glare). For example, a standard 200 nit LCD measured in a dark room has a 300 CR, but will have less than a 2 CR under strong direct sunlight. This is due to the fact that surface glare increases the luminance by over 200 nits both on the white and the black that are produced on the display screen. The result is that the luminance of the white is slightly over 400 nits, and the luminance of the black is over 200 nits. The CR ratio then becomes less than 2 and the picture quality is drastically reduced.

i-Tech sunlight readable LCDs with 1500 nits screen brightness will have a CR over 8 with the same amount of glare under the same strong sunlight, making the picture quality on these units extremely good. For further reading on contrast ratio, please see Tech Note 0101, Page 2, the Display Contrast Ratio.

The viewing angle is the angle at which the image quality of an LCD degrades and becomes unacceptable for the intended application. As the observer physically moves to the sides of the LCD, the images on an LCD degrade in three ways. First, the luminance drops. Second, the contrast ratio usually drops off at large angles. Third, the colors may shift. The definition of the viewing angle of an LCD is not absolute as it will depend on your application.

Most LCD manufacturers define viewing angle as the angles where the CR (contrast ratio)^3 10. For LCDs designed for less demanding applications, the viewing angle is sometimes defined as the angles where the CR^3 5.

For LCDs used in outdoor applications, defining the viewing angle based on CR alone is not adequate. Under very bright ambient light, the display is hardly visible when the screen luminance drops below 200 nits. Therefore, i-Tech defines the viewing angles based on both the CR and the Luminance.

All LCD backlights powered by cold cathode fluorescent lamps (CCFL) require inverters. An inverter is an electronic circuit that transforms a DC voltage to an AC voltage, which drives the CCFLs. i-Tech Technology manufactures inverters for all its products. Additionally, Applied Concepts and ERG also provide inverters for our products as well.

The dimming range or dimming ratio of an inverter specifies its capability of performing backlight luminance adjustment. For inverters used in notebook computers and LCD monitors, the backlight luminance can be adjusted typically over a dimming range of less than 10:1. That is, the luminance is adjusted from 100% down to about 10%.

For very high brightness backlights used in i-Tech Technology sunlight readable LCD modules, the inverters must be able to provide a much wider dimming range. Otherwise, the LCD screen will be too bright during nighttime conditions. Therefore, our inverters provide a typical dimming ratio of 200:1, meaning that the luminance can be adjusted from 100% down to 0.5%.

Any high brightness backlight system will consume a significant amount of power, thereby increasing the LCD temperature. The brighter the backlight, the greater the thermal issue. Additionally, if the LCD is used under sunlight, additional heat will be generated as a result of sunlight exposure. Temperature issues can be handled through proper thermal management design.

We provide TFT LCD with reflective mode of illumination without compromising its transmissive illumination. With the imposed reflective function, the modified LCD can reflect the ambient light passing the LCD cell and utilize the reflected light beams as its illumination. The stronger the ambient light is, the brighter the LCD will appear. As a result, the modified LCD is viewable under all lighting conditions including direct sunlight regardless the LCD"s original brightness.

The market demands for outdoor LCD applications are expanding, such as mobile navigator/video systems, PDA, personal organizer, Tablet PC, notebook computer, and Kiosk display etc. However, a regular transmissive LCD is very difficult to read under strong ambient light. This limits the outdoor applications of a conventional transmissive LCD.

The high bright LCD and the transflective LCD are the solutions generally utilized for outdoor applications. However, both solutions have some shortcomings. Because of the added lamps, high bright LCD creates some undesirable problems, which include high power consumption, excessive heat generation, increased dimensions, electrical circuit alterations, and shortened LCD lifetime. Thus, it is usually troublesome and costly to accommodate a high bright LCD in systems. Though giving good performance under the direct sunlight, the transflective LCD trades of its indoor performances.

Problems noticed in transflective LCD include narrow viewing angle, discoloration, low brightness, and loss of contrast. Moreover, the transflective LCD is currently limited in choice of sizes and resolutions.

On the other hand, a Transflective LCD is readable everywhere including outdoor environments without extra power consumption and excessive heat generation. The indoor viewing qualities are also enhanced. The modified unit fits right back into its original system with no need of any alteration and extra effort. Thus in your choice of size, resolution, and model, a direct sunlight readable LCD is conveniently incorporated into your device.

i-Tech is a premier supplier of optical bonding and performance added passive enhancements for all flat panel . i-Tech Optical Bonding process produces an optical bond between any display cover glass or touch panel, and any size LCD.

In the world of LCD"s, i-Tech takes display enhancement to a new level above all others. Utilizing advanced proprietary optical bonding technology; i-Tech overcomes optical challenges for display product manufacturers at an affordable price. In a wide range of applications, standard liquid crystal appear to "washed out" in high ambient lighting conditions. This wash out is due to excessive reflections and glare caused by bright light.

Commercially available LCDs, especially when protected by a separate cover glass or plastic shield, can not deliver enough brightness to make the display functional in outdoors or in other high ambient light applications. The exclusive Optical Bonding process from i-Tech provides a significant reduction of ambient light reflections at an affordable price, compared to other display enhancement technologies.

Optical Bonding seals either a top cover glass or touch screen directly to the face of the display bezel. Our bonding process eliminates the air-gap between the display and the cover glass, vastly reducing reflective light, which causes visual washout of the display image. Optical Bonding also enhances structural integrity by supporting the LCD assembly with the cover glass. The bond maintains perfect display uniformity while providing shock protection, unlimted humidity protection, and elimination of fogging caused by trapped moisture accumulating in typical air-gap assemblies.

Light travels through a variety of transparent materials; such as air, glass, plastic, and even water. These material"s abilty to transmit light is measured by their "indices of refraction". As light transfers from one material to another, such as air to glass, the differences the index of refraction will cause reflection. In the case of an air-to-glass interface, the reflection will be slightly less than 5% of the ambient light. All surfaces that have an index mismatch will reflect and the reflection is cumulative. In the case of a standard glass or plastic window, there are three surfaces with an index mismatch which will create a total relfection of nearly 15% of the ambient light. If the total reflection (in nits) is close to the displays brightness, the contrast of the display will be reduced to the point where the display"s readabilty is reduced to unacceptable levels.

Aside from the optical quality, Optical Bonding elminates the air-gap which prevents heat build-up from the "greenhouse" effect and prevents fogging from moisture or contamination from dirt or particles. It also offers shock protection and other damage to the LCD itself.

The anti-reflective coatings on the protection glass have excellent performance in tough ambient light conditions. With the normal glass, the strong reflection of the ambient light diminishes visibility and causes problems for viewer. Our special anti-reflective coated protection glass can increase contrast by enhancing light transmission rate over 95% (light reflectance rate less than 5%) and can effectively diminish the mirror images. The multi-layer vapor deposition coating either on one side or two sides of glass is designed to minimize reflectance and maximize transmittance.

Clearing Point - The temperature at which the liquid crystal fluid changes from a nematic into an isotropic state. In practice, a positive image LCD will turn totally black at this temperature and will therefore be unreadable. Because the clearing point is different for every fluid type, ask for design assistance from your supplier if high temperature operation is critical in your application.

Also, for most cases, both TN, HTN and STN utilize the phase known as nematic for display purpose. Within this phase, the liquid crystal has a "rod shape" exists within the solution which has fast response and has excellent electro-optic properties. This phase, however, only exists within a limited temperature range. The higher end of this temperature range is known as clearing point, above which, the liquid crystal lost its birefrigerance properties and cannot bend the light path anymore. Thus the polarizer will then be the only factor which affect incoming and out coming light. When the LCD is cooled down to below its clearing point, the display should be working again. The temperature for the clearing point varies greatly from material to material and you should contact our engineers regarding what you have. Normally a safe margin should be used to avoid clearing point when designing the display.

Light sensor detect the change of illumination outside, then it send the signal to MCU via I�2C interface. MCU will ask inverter to switch the brightness if the outside illumination was change over the default. MCU will transmit PWM signal to the inverter, amd the inverter will change the brightness of panel.

Winmate �light sensor� technology are now available for 8.4�, 10.4�,12.1�, 15�, 17�, and 19� LCD with specific panel option. Please contact with sales for more detail information.

The electronic controls effectively divide the screen into pixel sized sensing cells, using microfine wires which are not visible on a powered display. These wires are connected to a controller board, and an oscillation frequency is established for each wire. Touching the glass causes a change in the frequency of the wires at that particular point, the position of which is calculated and identified by the controller. Unlike other capacitive systems where the operator touches the actual conducting surface of the sensing panel, the active component of the sensor can be embedded up to 25mm from the touch surface ensuring long product life and stability.

The touchscreen can be supplied with the options of anti�glare or anti-reflection coatings, thermal toughening or chemical strengthening and privacy or contrast enhancement filters. The front glass of the touchscreen acts as a dielectric and enhances the capacitance of the touchscreen.

Recently there many end customer was mislead believing high brightness (over 2000nits, even up to 5000nits) is the better solution. But there are few concerns that the so called extreme high brightness (3000nits to 5000nits) panel manufacturer don"t tell you:

1. How much power consumption is the extreme high brightness LCD? It is very important because all of our outdoor LCD is in completely sealed enclosures keeping it cool is a very huge Challenge. Not mentioned the hot temperature around 40-50C area.

2. Also, you need to determine how far is viewer distance. Because high brightness (3000-5000nits LCD) might Damage eyesight if the viewer is too closed. LCD is design with high resolution for people to see it very closely, so extreme high brightness doesn"t make sense for outdoor LCD. If they want to put on extreme high brightness LCD on roof top to attract audience which LCD is not even big enough for seeing from far away. Most case customer will use LED which is more reliable and cost effective if it is larger than 82".

4. Viewable under sunlight is not just brightness only, it involve contrast ratio, reflection of the front glass and content graphics contrast such as (red and white). Sunlight readable is combination of all above, not just brightness only.

4. Viewable under sunlight is not just brightness only, it involve contrast ratio, reflection of the front glass and content graphics contrast such as (red and white). Sunlight readable is combination of all above, not just brightness only.

3. All the major branded LG and Samsung LCD manufacturer the most brightness that they do is only 1000-2000nits because we believe this major LCD maker already done a study on what is the most feasible and comfortable LCD brightness for outdoor. That"s why all the high brightness (3000-5000nits) maker is after market vendor without any study about the what is most suitable brightness for different applications, only advertising high brightness is not the solution. If you ask these vendor for outdoor enclosure which they will not provide or guaranteed it will work because they know it is a huge Challenge to cool down the display. Just like you are buying a 800 horse power car, but you still need to design the car frame and cooler to make this engine run safely on the road, which this extreme high brightness won"t help you to design that.

A few years ago there was widespread exuberance in the A/V consumer world when NEC or Panasonic announced that the newest version of their gas plasma display (that"s what we called them then) delivered an astounding 3000 to 1 contrast ratio. Today manufacturers advertise contrast ratios approaching and above 1,000,000:1.

Truth is that a 3000:1 contrast ratio would be almost unbelievable even today if evaluated on a post calibration, whole screen, ANSI checkerboard pattern basis. The highest I have measured on a recent flat panel display was nearing 1600:1.

For a long time, we in the A/V world have been harboring secrets about the testing methods used for such measurements as contrast. Contrast ratio stands out as probably the most blatant and ridiculous example of irrelevant manufacturers specifications.

used the backlighting to increase contrast by increasing brightness. LCD TVs often suffer from hazy, washed out blacks, especially when viewed from an angle greater than 30° off center.

Contrast ratio is the most important aspect of a TV"s performance. More than any other single metric, a set"s contrast ratio will be the most noticeable difference between two TVs.

In its simplest form, contrast ratio is the difference between the brightest image a TV can create and the darkest. In another way: white/black=contrast ratio. If a TV can output 45 foot-lamberts with a white screen and 0.010 ft-L with a black screen, it"s said to have a contrast ratio of 4,500:1.

There is no standard as to how to measure contrast ratio. In other words, a TV manufacturer could measure the maximum light output of 1 pixel driven at some normally unobtainable maximum, then measure that same pixel with no signal going to it at all. This hardly represents what you"d see at home, but without a standard, such trivialities don"t matter to TV manufacturers.

Worse, contrast ratio numbers have gotten so extreme, there is literally no way to measure some of them. What happens more often than not is the marketing department will come up with the number it needs to sell the product. The engineers will shuffle their feet, and stare at the wall, and magically the TV has that contrast ratio.

Because you"re reading this article on a device that has its own contrast ratio, I can"t give you real examples of what good and bad contrast ratios look like, so I"ll have to fake it. If you can, make sure your computer monitor is set decently; you can use

There are two more aspects of contrast ratio. Most often these are referred to as "native" and "dynamic." Native contrast ratio is what the display technology itself can do. With an LCD, this is what the liquid crystal panel itself is capable of. With DLP, it"s what the DMD chip/chips can do.

Imagine putting the image above on your TV"s screen. Native contrast ratio is how dark the darkest parts of the image are, compared with the brightest parts of the same image. I like to call this "intra-scene contrast ratio" though I"m certainly open to something better if anyone has an idea.

When an adjustable backlight, or a projector"s iris, is used in conjunction with circuitry to monitor the video signal, it is able to adjust the overall light output in real time depending on what"s onscreen. This dynamic contrast ratio looks like this:

A bright image is bright, a dark image is dark. Done well, this does increase the apparent contrast ratio of a display, but not nearly as much as the numbers would suggest. A TV with 5,000,000:1 contrast ratio would be unbelievable to look it. Too bad one doesn"t exist. A TV with a high dynamic contrast ratio may look better than a TV that has no such circuitry, but it won"t look as good as a display with a high native contrast ratio.

Yes, the LED"s of an LED LCD can turn off, creating a true black, but it will never do this when there is any amount of video on the screen. Picture the end credits of a movie. A display with a high native contrast will show this as a dark black background, and punchy white text. A display with a high dynamic contrast ratio may have a similarly dark background, but the text won"t be bright.

As you can see, a display with a high native contrast is the way to go, if that"s what you"re going for. The night sky is black, but the streetlights pop out. The day sky is bright, but the dark jacket is dark. This is more like CRT, more like film, more like life.

The technology with the highest native contrast ratio is... LCOS. At the moment, JVC front projectors using their version of the technology (D-ILA) have the highest native contrast ratios I"ve measured. Sony"s version (SXRD) comes in a rather distant second. Third is plasma, though some DLP projectors are close.

LCD has come a long way in the past decade, but still lags behind the other technologies. Thankfully, the better LCD manufactures know this and have come up with a few ways to mimic the high native contrast ratio of the other technologies.

The best way to get a high intra-scene contrast ratio with LCDs is with local dimming. This is when the backlight of the LCD is an array of LEDs, all of which can dim depending on what"s on screen. It"s not done on a per-pixel level, but LED zones are generally small enough that the overall effect is quite good. It"s far better than what the LCD panel can do itself. The downside is an artifact known as "halos" where the LEDs are lit behind small bright areas of the screen, but these areas are visible because the other parts of the screen are dark. This is very noticeable on specific types of content (like movie credits or star fields) but generally local dimming works really well. I was going to Photoshop some halos onto a screenshot of the one movie where I actually had a screen credit, but it came across more douchey

Most LED LCDs these days are "edge lit," as in their LEDs are along the sides (or the top and bottom, or both). Several companies have developed methods to dim areas of the screen with LED edge lighting, though the effect isn"t as good as full array LEDs. Again, every bit helps though, and many edge lit LED LCDs look amazing.

You may be asking yourself: How can you, as a consumer, find out what display has the best contrast ratio? Good question. You can"t tell in a store, as the store lighting will throw off any comparison (biasing towards LCDs or TVs with antireflective and/or antiglare screens that have better ambient light rejection). As mentioned, all manufacturers manufacture their numbers with little basis on reality, so spec sheets are out.

So that leaves reviews. Sadly, few review sites measure contrast ratio, and those that do don"t have consistency between them. There is no set standard for reviewers on how to measure contrast ratio either, so numbers are going to be extremely different. I may measure 20,000:1, while Joe Numbnutz over at TVAwesomeReviews.com measures 1,000:1 with his Datacolor Spyder (a decent product, but not a valid measurement tool for contrast ratio).

ANSI contrast ratio is a good addition. This is where eight-each white and black boxes in a checkerboard pattern are measured and averaged. This gives a good idea of what a display is doing, and is far more relevant to compare to actual video. Even this, though, is problematic, as the brightness of the white boxes can affect the measurement of the black boxes. Done right, it is also exceedingly time consuming. When I started measuring ANSI contrast ratio when I was at Home Theater, it nearly doubled the total amount of time spent measuring a television. Spending that much time on one measurement that most people will overlook is not an effective use of time.

Like nearly all TV buying guides say: It"s all in what you want to do with the TV. If you"re a movie buff and you watch TV in a dark room or at night, the added contrast of plasma will be very cinematic.

Somewhere in between is an LED LCD with some kind of local or zone dimming, offering better intra-scene contrast ratio than a "normal" LCD, but still offering that technology"s extreme light output.

Panasonic"s display arm, Panasonic Liquid Crystal Display Company, has announced the development of an in-plane switching (IPS) panel family boasting 1,000,000:1 static contrast ratio - the highest ever claimed by an LCD manufacturer.

Those who have been shopping for a monitor or TV in the last decade or so will be all too familiar with manufacturers" tendency to overstate the contrast - the distinction between fully-white and fully-black on the same panel - of their displays. Typically, this involves claiming a 1,000,000:1 "dynamic" contrast ratio - a trick which lowers the backlight level in dark scenes and boosts it in bright scenes to simulate high contrast. Panels based around organic light-emitting diode (OLED) technology, by contrast, have a high static contrast thanks to the ability to toggle the lighting on a per-pixel rather than per-panel or per-zone level, but these displays are more costly and complex to manufacture.

Panasonic"s display division"s new screens, though, are claimed to offer a 1,000,000:1 static contrast ratio for the first time in an IPS LCD panel - some 600 times higher, the company claims, than its nearest competition. The company"s technology is based around light-modulating cells permitting pixel-by-pixel control of backlight intensity in much the same way as OLED panels but, it claims, without the need to upgrade existing liquid crystal panel manufacturing equipment - greatly dropping the cost compared to retooling for OLED.

According to Panasonic"s internal testing, the panels treated with the additional layer of light modulating cells are capable of displaying a brightness of 1,000 candela per metre squared (cd/m²) and 0.001cd/m² simultaneously, without losing the viewing angles or colour gamut of the IPS panel. It plans to manufacture the panels in a range of sizes, from large-scale TV panels to professional-grade monitors for medical and industrial use and even down to in-car computer displays.

While there are many different manufacturers of LCD monitors, the panels themselves are actually only manufactured by a relatively small selection of companies. The three main manufacturers tend to be Samsung, AU Optronics and LG.Display (previously LG.Philips), but there are also a range of other companies like Innolux and CPT which are used widely in the market. Below is a database of all the current panel modules manufactured in each size. These show the module number along with important information including panel technology and a detailed spec. This should provide a detailed list of panels used, and can give you some insight into what is used in any given LCD display.

Note:These are taken from manufacturer product documentation and panel resource websites. Specs are up to date to the best of our knowledge, and new panels will be added as and when they are produced. Where gaps are present, the detail is unknown or not listed in documentation. The colour depth specs are taken from the manufacturer, and so where they specify FRC and 8-bit etc, this is their listing. Absence of such in the table below does not necessarily mean they aren’t using FRC etc, just that this is how the manufacturer lists the spec on their site.

If you’re in the market for a new TV, projector, camera, or any other type of display, you should pay attention to the contrast ratio. But what does this measurement mean, and how do you know whether your display has good contrast?

While most displays have a contrast setting that the viewer can manually adjust, the ratio refers to the panel’s limitations—in other words, the largest possible difference between its lightest (white) and darkest (black) areas.

Contrast ratio is the measurement of the difference between a display"s maximum and minimum brightness; put another way, it"s the ratio between the brightest white and the darkest black. For example, a contrast ratio of 1,000:1 means that the brightest white image is 1,000 times brighter than the darkest black.

Generally, a higher contrast ratio is better since a display with a 100,000:1 ratio can produce darker black levels and more saturated colors than one with a 1,000:1 rating, thus achieving a more natural-looking image. That said, a bigger number isn"t always better, as you need to take external lighting conditions into account the lighting conditions and the type of display into account.

As previously mentioned, a higher contrast ratio has its benefits but isn’t the only thing you should consider. For example, a projector with a lower contrast ratio could provide an optimal viewing experience if you’ll be using it in a room with a lot of ambient light.

Contrast ratios can also vary significantly across different display types. While a transmissive digital projector may only have a contrast ratio of 200:1, many newer TVs are over 4,000:1. But even these figures don’t tell the whole story, as contrast ratios are dependent on the underlying technology and how they are measured.

When looking at a display’s contrast ratio, it’s important to understand the various ways in which they are measured. The actual ratio you see can be broken down into two different types: Static Contrast and Dynamic Contrast.

Static Contrast, otherwise known as “native” or “onscreen,” is a ratio comparing the brightest and darkest shade a display system is capable of producing at the same time. Since this ratio reflects the results from when the panel was made, industry experts typically consider this a more accurate representation of a display’s capabilities.

Dynamic Contrast offers a more theoretical range of a display’s contrast ratio, as it’s heavily dependent upon the screen’s underlying technology. Here, the range between the lightest areas of an all-white/light scene and the darkest areas of a black/dark scene is measured.

The problem with dynamic contrast measurements is that they are typically dishonest, as you’re unlikely to experience such a wide contrast range in the same scene. On top of this, manufacturers can manipulate contrast to make a scene lighter or darker using a display’s backlighting and firmware.

Unfortunately, there is no standardized measurement of contrast ratio. Particularly in the TV market, manufacturers can essentially inflate their ratings due to a combination of measurement and unstated variables. That said, most contrast ratios are measured using one of two methods:

Displays that measure with this method tend to register lower contrast ratios as ANSI contrast provides a more realistic measurement of the screen’s capability. However, since the test can include a room’s lighting conditions in its measurement, it needs to be performed in an ideal environment for the most accurate reading.

This method measures an all-white screen with an all-black screen and reflects equal proportions of light from the display to the room and back. It"s the preferred method for many manufacturers, as it cancels out exterior lighting conditions and results in an ideal (and thus higher) contrast ratio. Unfortunately, dynamic contrast specs are often misleading since they can be inflated and don"t indicate much about how an average image"s contrast will look.

The eye test is the best tool at your disposal — if a display’s black levels look washed out and gray, its contrast ratio probably isn’t high enough. However, there are other ways to ensure you’re not being misled:

Look for vendors that publish ANSI contrast specs, as this is a more accurate reflection of the display’s true contrast range. Unfortunately, many companies don’t disclose these figures, as ANSI readings tend to be much lower than Full On/Off, and it’s simply a better marketing strategy for these companies to focus on the latter.

Pay attention to backlighting technology.If you’re looking for a TV with a high contrast ratio, an OLED display will offer a better viewing experience than an LCD panel, as the OLED’s pixels don’t rely on a backlight and can display deeper blacks without a “blooming” effect.

Stick to the same manufacturer when making comparisons.Since every company arrives at its contrast ratios through different means, comparing displays produced by the same manufacturer is an excellent way to get consistent figures.

As it pertains to monitors, the contrast ratio is the ratio between the brightest white’s highest lumination level and the deepest black color the monitor is capable of producing. If a monitor has a high contrast ratio, it means it offers deeper shades of black, indicating a higher level of picture quality overall.

Contrast ratio is crucial for projector image quality. The higher the contrast ratio, the more detail viewers can see on the image projected. A higher contrast ratio also means more color subtlety is available, and more shading is visible.

Modern computer LCD monitors typically have a contrast ratio of between 1000:1 and 3000:1. A good gaming monitor may range toward the higher end of the spectrum, but use your eyes when considering a monitor you"re comfortable with and note that ambient light will affect what you"re seeing.

As a first step, try using the calibration settings we recommend (provided we have reviewed your monitor). This will get good, basic contrast - meaning no additional contrast-enhancing settings - and with no loss of detail in dark portions of the image. You can find this information in the "Post Calibration" section of the review.

Contrast:Adjusting this will let you affect how much contrast the monitor has. We list a recommended setting with all of our reviews, but it"s almost always fine to just set this to the maximum. On rare occasions, gamma might be affected, leading to a loss of detail in highlights.

Local Dimming: The local dimming feature dims the backlight behind darker portions of the screen. It can deepen contrast, and it"s worth using when implemented well. It can introduce issues like light blooming off of light objects within dark areas, and when done especially poorly, can dim the entire image. We discuss local dimming in more detail here.

Backlight settings have a very minor impact on contrast, and so you should set it to whatever looks best in your viewing space. With LED Monitors, both white and black will become about equally brighter or dimmer when the backlight is adjusted, preserving the ratio of light to dark. With OLED monitors, adjusting the OLED light only increases the peak brightness; blacks are still perfectly black.

One frequently asked question is which is more important, a panel"s native contrast or contrast with local dimming? It"s a good question. The answer is a bit complicated, but basically, it depends. Unlike TVs, most monitors don"t have a local dimming feature. The few that do, generally speaking, don"t work very well. They usually have very small zone counts, and the algorithms can"t keep up with fast-paced motion, so the leading edge of a bright object in a dark scene ends up looking darker than the rest, and there"s a trail of light behind it.

Because of these issues with local dimming, it"s almost always more important to look at the native capabilities of a monitor instead of the contrast ratio with local dimming. Because most monitors have poor local dimming features, there"s usually not that much of a difference between the native contrast of the panel and the contrast with local dimming when tested with a checkerboard pattern. In fact, of the 23 monitors with local dimming that we"ve tested on our latest test bench, only 4 of them can improve contrast by 10% or more with our test pattern through local dimming.

There are different ways to measure contrast. We measure contrast with a checkerboard pattern and take the average black level from four squares, but some other review sites measure it differently, which can lead to a difference in posted numbers. Some of the other methods we"ve seen websites use include:

Full On/Off: Some websites measure the contrast using a full white screen, and a full black screen. This is generally considered a less accurate way to measure contrast, and it isn"t very realistic. Contrast measurements with local dimming tend to appear much better with this measurement technique, as it"s easy for any monitor with local dimming to turn the entire screen off at once.

Small Samples: Similar to the full-screen method, but instead of large slides, contrast is measured using small slides that only cover part of the screen. This method isn"t ideal either, as imperfect uniformity can significantly skew the results.

ANSI Checkerboard: The most generally accepted way to measure contrast; a checkerboard pattern very similar to ours is used, but with an asymmetric test pattern. The ANSI method measures the output in all 16 squares and averages the values for the white and black squares. It usually produces very similar results to our own.

Because of differences in measurement techniques, equipment used, and even differences between units, it"s extremely common for different websites to report different contrast measurements.

Monitors use different display technologies, each with advantages and disadvantages. Knowing which type of panel is used in your monitor can already give you a good indication of what to expect in terms of contrast ratio:

OLED: Very few OLED monitors exist, but they essentially have perfect contrast, as each pixel is self-emissive, the black level of black pixels is essentially zero.

Even within the same panel types, it"s normal for the contrast to vary a bit between units, even of the same model, due to manufacturing tolerances. Manufacturers used to provide the typical contrast ratio for each monitor, but recently, some brands, including LG, have started listing the minimum contrast ratio you could get. For IPS and TN panels, this difference usually isn"t very significant, and most people shouldn"t worry about it, but for VA panels, the variance between individual units and measurement techniques can be significant. For example, the LG 32GN600-B is advertised to have a typical contrast ratio of 3000:1, but according to LG, it could be as low as 1800:1 for some units. We measured a contrast ratio of 3248:1, almost double the minimum contrast for that model.

A monitor’s contrast ratio indicates the depth of blacks – a higher contrast ratio means deeper blacks – and, by extension, better picture quality. It’s a very important part of picture quality, so if you want something that looks good (particularly in a dark room), be sure to get a monitor that has good contrast.

There are a few things that can be done to improve contrast, but there are limits. As a good first step, look to our recommended picture settings (listed with every review), as those can help you get a good baseline. From there, you can enable or disable a few different settings that might help deepen blacks. Just remember that some of those settings will have other consequences on picture quality.

In order to choose the best monitor for your needs, it is very important to distinguish what kind of LCD panel interface type is in the monitor you’re looking at. The most common panels used nowadays are;

One of the types of panels that you will find in a computer monitor is a TN Panel. This stands for Twisted Nematic, and this particular type of LCD panel is generally the cheapest. They are the cheapest to manufacture among all LCD technologies, so they are the most commonly used in budget monitors.

If you are looking to game online, you will need a monitor with a higher refresh rate like that offered by a TN panel. Refresh rates are measured in Hertz (Hz), which defines how many times per second your screen can display new images.

The typical response time for a TN panel is less than 5 ms which is much faster than the 6 or 8 ms response time that other LCD displays have, such as vertical alignment or VA.

The biggest downside with these panels is often their viewing angles. On a TN panel, the viewing angles aren"t very good, and depending on how far off-center you are, the picture can begin to lose color and contrast.

TN panels also don"t support as wide a range of resolutions as IPS. This LCD monitor panel type has a poor contrast ratio when compared with other technologies such as IPS and VA. This results in an inability to display deep blacks and bright whites at the same time.

TN panels are manufactured by Samsung, LG, AUO, Chi-Mei, Chunghwa Picture Tubes, Hannstar Display Corporation, Sharp Corporation, CMI, Innolux, J-Tech Digital Imaging Co. Ltd, AU Optronics Corporation, etc.

A TN panel is a type of liquid crystal display (LCD) used in most LCD monitors and laptops. TN panels were the workhorse of the 1990s and early 2000s, but they were eventually replaced by their more-expensive cousins, the in-plane switching (IPS) and vertical alignment (VA) panels.

TN computer panels work by using two polarized filters, vertical and horizontal, to control the light that passes through them. The filters are arranged so that when the electrical current is off, light cannot pass through. When it"s on, it hits the twisted crystals to produce colors. The active layer is twisted to allow the light to pass through it, and this twist is controlled by electrical fields applied to the liquid crystal material.

It is worth noting that A TN panel is made up of millions of pixels, each pixel being red, green, or blue in color. The light from each pixel can be either on or off, so black is created when all the pixels are off and white when all are on. When all three colors are combined, any color can be produced. This arrangement is called RGB (red-green-blue).

A TN panel uses twisted nematic liquid crystals to form images. While not as desirable as other technologies, it does have several benefits worth considering when making a purchasing decision.They are mostly found in budget LCDs, as they are cheaper to manufacture and therefore sell for less.

TN panels have excellent response rates and refresh rates, typically 1 - 2 milliseconds and 50 – 75 Hz, respectively. This makes them ideal for high-end gaming

TN is the oldest and most common type of LCD panel, and it"s also the cheapest to produce. TN panels were the first panels to be introduced to the market, but they"re no longer as popular as they used to be. This is because TN panels have several downsides:The main disadvantage of TN panels is limited viewing angles, which can be extremely limiting in some cases. If you"re sitting straight in front of the monitor, everything is fine, but if you move to the side, then all colors shift and get distorted. That can be extremely annoying for graphic designers or architectswho work with color palettes, photographers who need exact color matching, etc. (see also

TN panels typically have lower contrast ratios than IPS displays do, so they don"t look as rich in color or dark black. So TN panels are usually not suitable for professional applications such as color-critical photo editingand graphic design.

Many gamers prefer TN panels because they provide a very fast response time and higher refresh rates. You can also find some with a refresh rate of 240Hz, which is even better.The Asus VG248QE is a 24-inch LCD display with a 1920 x 1080 resolution and a 1ms response time. It uses a TN panel, so don"t expect much in terms of viewing angle or color reproduction accuracy compared to an IPS display. But if you"re looking for a good 144Hz monitor, choose this one.

ViewSonic VX2458-MHD. It has a TN panel. The refresh rate of this monitor is 72Hz, which is standard. The response time of this monitor is 1ms. It also comes with 4 USB 3.0 ports, which is great if you plan on hooking up multiple devices, which is frequently used when trading. If you have a setup like that, you will also want to look at bezel less monitors, or frameless monitors, for your needs.

Another common type of panel is a VA panel. This stands for Vertical Alignment and is a step above a TN panel in terms of quality. Its name comes from the fact that light emitted from the screen"s backlight (see also LED monitors) is aligned vertically rather than being scattered horizontally and vertically as it is with a TN display.

VA panels provide high-quality images, wide viewing angles along with excellent contrast ratio and high refresh rates. These factors make VA panel monitors preferred for graphic design, photographers, video editors, and others who often work on their PCs.

VA panels are also better when displaying fast-moving images because they offer high refresh rates hence have less motion blur. Additionally, some panels have support for even 120 Hz refresh rates for ultra-smooth movement in games and movies.

Unlike a TN display, a VA display has excellent viewing angles. You can view them from any direction, and you won"t see any distortion in the display. They make them a good choice for home theater systems as it allows users to be seated off-center without affecting the image quality or contrast ratio.

Traditional LCD displays use two polarizing filters and liquid crystals (LCs) to create all the colors and patterns that we see on computer monitors and flat-panel televisions.

What are the Benefits of VA Panels?Image quality of VA technology is considered better than TN technology; text appears crisper, and images appear sharper and richer in contrast and color.

One of the other key benefits of VA technology is its high contrast ratio; VA displays can deliver a true black when displaying dark images or video content

The big downside of TN panels is their response time. Most TN panels have a response time of 5-8 MS, which is fine for most people. However, if you"re mostly into competitive gaming or fast-paced action games like me that require quick reflexes, then this could be a problem.

We did some research and came up with a list of the best monitors with VA panels, and they are;ViewSonic VX2457-MHD. It is a24-inch monitor with a 1920 x 1080 resolution and covers 100% of the sRGB spectrum. It also has plenty of picture-enhancing features, including adjustable color settings and support for AMD"s FreeSync technology (see also affordable G Sync monitors).

This is the best LCD panel type. IPS stands for In-Plane Switching, and the biggest advantage over the other panels listed above is its wide viewing angles.

These screens are more expensive than TN panels but offer a greater contrast ratio, higher resolutions than their TN counterparts. They also support higher refresh rates, lower response time which makes them ideal for monitors larger than 24 inches.

These panels offer much more consistent colors, which makes them ideal for graphic designers or anyone who does any kind of color-critical work on their monitor.

IPS panels offer wider viewing angles than VA panels do, making them better suited for use in public spaces such as retail stores or airports where you can expect people will be walking by your TV from both sides.

The contrast ratio of an IPS panel is higher than that of TN panels. The contrast ratio of a display refers to the difference between the darkest black and the brightest white that the display is capable of producing. This can be an important factor in overall display quality, depending on how you use your laptop or desktop monitor.

A high contrast ratio is important for good reasons. A good contrast ratio makes details easier to see, so you can enjoy your movies more and your games more challenging. It can also make it easier to work outside in bright sunlight.

Some manufacturers that specialize in IPS panel interphases include Samsung, LG, and even Mac Apple. Also, almost all Dell monitors use IPS panels. However, there are plenty of other high-quality manufacturers that also offer IPS panels for you to choose from.

In a liquid crystal display (LCD), light passes through a pair of polarizers. Each polarizer is made of a long chain of molecules, each oriented in a different direction; one vertical, the other horizontal.

In an IPS LCD panel, liquid crystals are aligned so that both polarizers face the same way—horizontal. Light from behind the panel passes through one polarizer and then bounces off onto a second polarizer before reaching your eyes. This design makes IPS LCDs nearly as bright as VA panels and much brighter than TN panels without sacrificing contrast ratio or color accuracy.

If you"re looking for a new monitor, IPS panels may be the right ones for you. Here are some of their most important benefits:It allows for wider viewing angles. This is very useful for monitors used at work that involve customer service, where the monitor may be viewed from many different angles.

The IPS LCD displays are also characterized by their high degree of brightness and contrast, which makes them ideal for outdoor use, among many other features.

The typical lifespan of an IPS panel is around 100,000 hours, which is more than enough for even heavy users to get their money"s worth from their monitor.

They have great color reproduction. Many people who are serious about a photo or video editing are drawn to IPS panels because they offer superior color reproduction possibilities when compared with TN panels.

The main disadvantage of IPS panels is that they are more expensive than TN panels. The cost of an IPS panel will typically be $10-$20 higher than a comparable TN panel.

Today, the majority of flat-panel monitors use in-plane switching (IPS) technology. Best monitors that have IPS panels include;Samsung U28E590D 28-Inch 4K UHD Monitor. If you love gaming, then this is the product for you; it comes with AMD FreeSync, which proved successful in eliminating screen tearing since being introduced as VSync, as this post explained.

The Acer H236HL bmijpphzx is one the best IPS monitors on the market today. This monitor has an extremely high 2560×1440 resolution along with a 1,000:1 contrast ratio and a 160-degree viewing angle.

Also, bear in mind that if it is a flat panel display with a 1080p resolution or higher, you can refurbish it and resell it after using it. Older monitors with lower resolutions may not be worth much.

It offers a much higher resolution than conventional LCD and can be used to manufacture large panels. It"s an innovative display technology that has the potential to change the face of consumer electronics.

There are 3 main types of LCDs; VA (Vertical Alignment), TN (Twisted Nematic), and IPS (In-Plane Switching). All these technologies have been used for over 10 years and have their own pros and cons. However, they have reached their upper limits in terms of resolution and other features, and it"s nearly impossible to increase them any further. That"s where Super PLS-Plane to Line Switching comes in.

Super PLS-Plane to Line Switching offers resolutions as high as 8K, has wider viewing angles, and is brighter. The image quality presented by this technology is said to be much better than traditional LCDs, and it could potentially disrupt the current.

The Nano IPS panel technology adds a layer of nano-particles to the backlight in order to transmit the screen"s picture more efficiently and reduce the chances of image retention.

Advanced Hyper-Viewing Angle (AHVA) computer display was developed by AU Optronics Corp. It is a type of LCD that can be seen clearly even from the most acute angles. Through the process of strengthening the polarizing plate, it can help minimize the reflection ratio to less than 1%. The viewing angle is about 178 degrees.

Most LCDs (liquid crystal display) monitors are now manufactured with an anti-glare coating to reduce the effect of ambient light reflecting off the screen. Anti-glare coatings can reduce reflections by 25 to 70%.

VA panel is better thank IPS. Although IPS panels have a contrast ratio of 700:1 to 1500:1, they are still inferior to VA panels. The majority of VA monitor panels have contrast ratios above 2500:1, and some even reach 5000:1 or 6000:1. Even local dimming is used by more recent monitors to obtain even greater contrast ratios.

Yes, IPS is better than OLED. The main benefit of IPS panels is their increased brightness, particularly when combined with a tiny LED backlight. OLED displays are often limited to brightness levels of roughly 1,000 nits, while mini LED displays can reach peak brightness levels of around 2,000 nits.

A "Sunlight Readable" LCD is a LCD screen which can be viewed directly under sunlight. The brightness of a "Sunlight Readable" LCD is supposed to be over 1000 nits (or cd/m²). NAVPIXEL series integrates this special technology to be able to present the clearest picture and assist you in making the best decision during your cruise.

NAVPIXEL series takes LED panels for many features. In addition to the main feature - no mercury, LED backlight panels have more advantages such as wide operation temperature range (-20℃ ~ 60℃) and lower power consumption (up to 70K hours). Those are great benefit to marine applications.

The “Wide Dimming” technology provides the wider brightness adjustment level to meet variety of requirements. Through the user-friendly VR knob, people can adjust the dimming ratio from 0% to 100%. The high sensitivity and complete adjustment design make NAVPIXEL series to meet different workplace requests.

Combining the sunlight readable LED backlight LCD panel with the “Wide Dimming” technology, NAVPIXEL series can offer a crisp and excellent contrast image for many marine applications.

To enhance the contrast ratio and to reduce refection, NAVPIXEL series takes AOT (Advanced Optibond Technology) to overcome many optical challenges. In a wide assortment for many applications, the exclusive glass bonding process can result in a reduction of ambient light reflections truly to present better visual display. In addition, the technology can absorb vibration to enhance the strength of NAVPIXEL series as well.

Taken special Anti-reflective (AR) coatings, those panels of NAVPIXEL series can present better display performance. Anti-reflective (AR) coating is a type of optical coating applied to the surface of lenses and other optical devices to reduce reflection. This improves the efficiency of the system since less light is lost. The reduction in reflections also improves the contrast of the image by elimination of stray light. In marine applications, the technology will approve more elegant visual performance and safer working process.

A touchscreen is a display which can detect the presence and location of a touch within the display area. NAVPIXEL display and panel PC can take “Resistive Touch” or “Infrared (IR) Touch” to contribute a more intuitive environment.

A resistive touchscreen panel is composed of several layers. The most important are two thin metallic electrically conductive and resistive layers separated by thin space. When some object touches this kind of touch panel, the layers are connected at certain point; the panel then electrically acts similar to two voltage dividers with connected outputs. This causes a change in the electrical current which is registered as a touch event and sent to the controller for processing. The Nintendo DS is an example

To decrease the power consumption and to keep a water-tight working system, many of NAVPIXELTM series marine computing solutions take fanless design to add the operation stability for marine application. In other harsh working environment, the fanless design can ensure the stability of working system as well.
