are lcd displays good in stock

NEW YORK (TheStreet) -- A good $5 stock is hard to find, especially one that is sitting in the middle of an enormous growth curve in the red-hot tech sector.

This nearly $4.9 billion company is a Taiwanese manufacturer of flat panel displays used in a wide variety of consumer electronics products such as high-def televisions, smartphones, notebook computers, and the touch-screen technology now being used in automobiles and payment-processing terminals.

Roughly 20% of large thin-film transistor LCD (TFT) panels in the world are produced by AU Optronics. Almost all Sonyundefined televisions in 2014 used AU Optronics flat panels, while Panasonic, LG(, Toshiba, Philips

The reason our Piotroski model ranks AU Optronics so highly is that it aces four of his most critical tests, the first of which compares a company"s book value to its current stock market capitalization. In this case, the company has a book-to-market ratio of 1.05, placing it in the top 20% of the more than 6,000 stocks that we measure. A ratio in excess of 1.0 implies that a stock is currently priced at less than the company"s actual value from a balance sheet perspective, suggesting that sooner or later that excess value will be recognized by the market.

In short, AU Optronics is one of those very rare stocks that has been improving its financial condition while providing a product that is in huge demand, yet appears to still be undervalued and is priced at only $5.

Regardless, you can confidently acquire AU Optronics now for a strong gain, with good downside protection, as the market brings the the company"s stock price in line with its book value.

Creating an array of the best LCD Monitors for Stock Traders is one of the many ways you can make money on your PC. Unlike gaming rigs which require high-speed refresh rates and response times, you will only need clarity and a perfectly sized display to cater to your needs. This niche can involve a lot of different software at any given time, so your best bet is probably a multi-display machine.  You want a set up that allows you scan multiple markets at the same time, decreases eye fatigue, offers high resolution, maximizes speed and keeps costs down.  The setups below are more affordable and responsive than your standard Bloomberg terminal monitor.  Users of TradeStation, Thinkorswim, and eSignal will benefit from the expansive real estate of a multi-monitor setup.

Setting up a command center-styled system can get tricky or expensive, but there are practical solutions you can easily purchase and build yourself. Determining how many displays you will require maximizing efficiency and productivity is key.

However, if your stock market business runs several windows which monitor different markets, clients, brokers or you just need the extra viewing space, you can opt to utilize a mounting mechanism which can hold up to six different displays

The cheapest solution we can find and recommend is the VIVO Hex LCD Monitor Stand, which can hold up to six 24-inch monitors via their 75 x 75 or 100 x 100 VESA mounting holes. This mechanism is made of high-grade steel and aluminum for durability.

Each arm will provide -15 to +15 degrees of tilt, and 360 degrees of swivel and pivot, giving you absolute control over how you would want to position each screen to get the perfect view angle. You also won’t need to worry about messy wires, since the VIVO Hex LCD Monitor Stand also includes an integrated cable management system.

The IPS panel appears crisp and vibrant especially if you use the included sRGB mode in the OSD, which produces a Delta E result of only 1.80. You sacrifice a bit of contrast in this mode, but we can’t argue with correctly saturated images and accurate colors which are often associated with high-end monitors.

If multiple monitors for stock trading isn’t your cup of tea, there are products which are suitable for the job. Having a lone monitor on your desk can be practical in both cost and upkeep, plus you don’t have to deal with messy cabling or assembly.

The Philips BDM4350UC carries a high-quality IPS panel with eye-popping color and detail, plus our review unit did not display any severe backlight bleeding or poor uniformity, which is quite rare for big screens. This option is excellent for designing and movies, and we can’t imagine why it shouldn’t be included as one of the best monitors for stock trading.

The LG 34UC97 is an excellent ultra-wide monitor with an IPS panel with 99%  coverage of the sRGB gamut. This color-accurate wonder gently curves with a 3800mm radius giving its users a perceived wrapped-around feeling which can enhance immersion and focus. You can also split the screen into several configurations via LG’s Screen Split software according to your needs.

The LG34UC97 is a work of art, thanks to its borderless face and luxurious furniture clad in chrome and metal textures. You get a mild degree of articulation with the included stand, but we reckon users will rarely need to adjust the whole thing to get a perfect viewing angle. Your modern devices can also benefit from the modernism of this model since it is equipped with a Thunderbolt port for USB-C devices such as the new MacBooks.

Choosing the best monitors for day trading does not need to be tricky or difficult, since the market is full of several solutions which are suitable for different needs and budgets. The seven recommended products here represent benchmarks according to our rating, tastes, and experience so you can gauge how to build a setup for trading of your own.

You can also select monitors from some of the best the gaming industry has to offer, but in our opinion, their capabilities are wasted and they are usually too expensive for this sort of thing. The goal is to be as practical as much as possible, even if there are high-end offerings which provide utilitarian features in exchange for their price tags.

One of the most common questions we’re asked when assisting businesses establish their digital signage systems is whether an LED or an LCD display is best for their business. The answer is always contextual to the clients’ needs. It starts by clarifying what the difference between the two actually is.

When we’re talking aboutconsumer products such as computer monitors and televisions the first thing to know is that an LED screenis an LCD screen, but an LCD screen is not always an LED screen. An LED monitor or television is just a specific type of LCD screen, which uses a liquid crystal display (LCD) panel to control where light is displayed on your screen.

For the display to be considered an LED screen, it means it is utilising ‘Light Emitting Diodes’ to generate the light behind the liquid crystals to form an image. A non-LED LCD screen has backlights (called fluorescent lamps) behind the screen that emit white light which cannot pass through the liquid crystals until an electric current is applied to the liquid crystals which then straighten out and allow light to pass through.

This is where it can get easy to divert away from giving clear advice on whether as LED or LCD display is best for your business, because consumer displays differ from commercial displays. We are not trying to give the reader direction on which monitor is best for their gaming set-up, but which screen type is ideal for communicating your business’ messages.

Commercial LED displays are typically referred to as Direct View LED. This is because they use LEDs as the individual pixels that make up the image itself. Using a surface array of LEDs removes any need for a liquid crystal display panel, which carries noticeable benefits for particular uses.

While LCD flat panels are available in resolutions of 1080P and 4K UHD, Direct View LED displays are measured by pixel pitch. Pixel pitch is the distance from the centre of one pixel cluster to the centre of the next pixel cluster in an LED screen. The smaller the pitch, the closer viewers can get to the display before they see the pixels themselves. Outdoor configurations may have a pitch of 10mm to 40mm, as they are viewed at longer distances.

For use indoors, where viewers would be closer to the display, a pitch of 10mm or less would be required, some have even sub-1mm pixel pitch. When considering Direct View LED displays, it is important to know the minimum viewing distance required. Multiplying the pixel pitch by 1,000 gives you a good rule of thumb for the minimum viewing distance.

Direct view LED displays can either use discrete oval LEDs which are basically one single self-contained diode, or Surface Mounted Device (SMD) LEDs. SMD LEDs contain 3 individual light-emitting diodes bunched together. Either way, it’s the light-emitting diodes that create the images you see on screen. This is explained in the image below, courtesy of LG Electronics

Commercial LCD screens are more closely related to their consumer counterparts like TVs but there are still differences to be aware of. It is not advised to simply purchase an LCD TV from your local electronics retailer and install it in a public setting and expect it to function as desired.

Both have been designed to be used differently. Commercial display manufacturers understand that their displays are going to be exposed to far different conditions than a living room television will be. The componentry in a commercial display is optimised to allow for the display to be on 24 hours a day, all year around. They take into account diverse environments such as hot kitchens, high foot traffic, and bad weather,ensuring the product won’t fail in such exposures. The addition of more durable and resistant technology means commercial LCD displays will typically be priced higher than their consumer cousins.

Brightness: When deployed in areas with strong ambient lighting, even the best LCDs can appear washed out and difficult to view, especially when from an angle. Direct view LEDs for outdoor applications can reach 9,000 nits, making them a brighter and better choice for most outdoor applications.

Contrast: Direct View LEDs can turn off pixels that aren’t being used which allows for a higher contrast and therefore a richer image in varied lighting conditions.

Size and shape: Direct view LED-based walls can be flat, curved, wrapped around pillars and more. With no size limit or set aspect ratio they can be used more flexibly than LCDs. Plus, panels have no bezels which means you can piece together Direct view LEDs to create large and uniquely shaped displays with no visible interruptions between units.

Lifespan and servicing: Most direct view LEDs are rated to last 10 years, compared to a typical 5 years for LCDs. Further, they can be easily replaced on-site, reducing maintenance costs.

Tougher: If you’re using an LCD for any outdoor application or one where the unit has to be protected from extreme temperatures or humidity, you’re going to need to include an enclosure and have an understanding of how to properly seal and vent the unit. Outdoor Direct view LEDs, on the other hand, are purpose-built to withstand harsh environments.

Price: The higher upfront cost of Direct LEDs could be the biggest sticking point when it comes to pitching a video wall. While prices have been steadily dropping, Direct view LEDs are still more expensive than LCD alternatives. However, make sure you consider the lifetime cost of the solution and other benefits mentioned above before you discount direct view LEDs.

Functionality: LCD screens can offer a wider range of functionality when it comes to set-up, display settings, and day-to-day control. There is also the addition of touch screen options for LCD displays which are a fairly sought-after feature these days.

Resolution: Whilst the fine pixel pitches available in direct view LEDs today make for impressively resolute images, LCD screens still boast are more uninterrupted image when viewed up close, particularly with the modern 4k displays. This makes them a better option for smaller retail stores, quick service restaurants or office meeting rooms.

As earlier stated, intended use for the display will determine which format you invest in. In outdoor environments or areas with high ambient lighting, brightness is the key concern. For indoor environments, the key concern is image quality and contrast. It’s also imperative to consider the usage environment and what the screen may be exposed to with regards to weather, temperature, humidity, direct contact and other factors. If you have a good understanding of your requirements for content, application, perception and budget then your first move should be to contact a supplier, like Black Lab Design, and we will be able to assist you with designing, building and installing the perfect digital display solution for your business.

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. Liquid crystals do not emit light directly, instead using a backlight or reflector to produce images in color or monochrome. LCDs are available to display arbitrary images (as in a general-purpose computer display) or fixed images with low information content, which can be displayed or hidden, such as preset words, digits, and seven-segment displays, as in a digital clock. They use the same basic technology, except that arbitrary images are made up of a large number 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 portable consumer devices such as digital cameras, watches, 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 increase the lifespan of LCDs are quantum dot displays, which offer similar performance as an OLED display, but the Quantum dot sheet 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. The LCD screen is more energy-efficient and can be disposed of more safely than a CRT can. Its low electrical power consumption enables it to be used in battery-powered electronic equipment more efficiently than CRTs 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.

In one corner is LED (light-emitting diode). It’s the most common type of display on the market, however, it might be unfamiliar because there’s slight labelling confusion with LCD (liquid crystal display).

For display purposes the two are the same, and if you see a TV or smartphone that states it has an ‘LED’ screen, it’s an LCD. The LED part just refers to the lighting source, not the display itself.

In a nutshell, LED LCD screens use a backlight to illuminate their pixels, while OLED’s pixels produce their own light. You might hear OLED’s pixels called ‘self-emissive’, while LCD tech is ‘transmissive’.

The light of an OLED display can be controlled on a pixel-by-pixel basis. This sort of dexterity isn’t possible with an LED LCD – but there are drawbacks to this approach, which we’ll come to later.

In cheaper TVs and LCD-screen phones, LED LCD displays tend to use ‘edge lighting’, where LEDs sit to the side of the display, not behind it. The light from these LEDs is fired through a matrix that feeds it through the red, green and blue pixels and into our eyes.

LED LCD screens can go brighter than OLED. That’s a big deal in the TV world, but even more so for smartphones, which are often used outdoors and in bright sunlight.

Brightness is generally measured as ‘nits’ – roughly the light of a candle per square metre. Brightness is important when viewing content in ambient light or sunlight, but also for high dynamic range video. This applies more to TVs, but phones boast credible video performance, and so it matters in that market too. The higher the level of brightness, the greater the visual impact.

Take an LCD screen into a darkened room and you may notice that parts of a purely black image aren’t black, because you can still see the backlighting (or edge lighting) showing through.

You’ll often see a contrast ratio quoted in a product’s specification, particularly when it comes to TVs and monitors. This tells you how much brighter a display’s whites are compared to its blacks. A decent LCD screen might have a contrast ratio of 1,000:1, which means the whites are a thousand times brighter than the blacks.

Contrast on an OLED display is far higher. When an OLED screen goes black, its pixels produce no light whatsoever. That means an infinite contrast ratio, although how great it looks will depend on how bright the screen can go. In general, OLED screens are best suited for use in darker rooms, and this is certainly the case where TVs are concerned.

OLED panels enjoy excellent viewing angles, primarily because the technology is so thin, and the pixels are so close to the surface. You can walk around an OLED TV or spread out in different spots in your living room, and you won’t lose out on contrast. For phones, viewing angles are extra important because you don’t tend to hold your hand perfectly parallel to your face.

Viewing angles are generally worse in LCDs, but this varies hugely depending on the display technology used. And there are lots of different kinds of LCD panel.

Thankfully, a lot of LCD devices use IPS panels these days. This stands for ‘in-plane switching’ and it generally provides better colour performance and dramatically improved viewing angles.

IPS is used in most smartphones and tablets, plenty of computer monitors and lots of TVs. It’s important to note that IPS and LED LCD aren’t mutually exclusive; it’s just another bit of jargon to tack on. Beware of the marketing blurb and head straight to the spec sheet.

The latest LCD screens can produce fantastic natural-looking colours. However, as is the case with viewing angles, it depends on the specific technology used.

OLED’s colours have fewer issues with pop and vibrancy, but early OLED TVs and phones had problems reining in colours and keeping them realistic. These days, the situation is better, Panasonic’s flagship OLEDs are used in the grading of Hollywood films.

Where OLED struggles is in colour volume. That is, bright scenes may challenge an OLED panel’s ability to maintain levels of colour saturation. It’s a weakness that LCD-favouring manufacturers enjoy pointing out.

Both have been the subject of further advancements in recent years. For LCD there’s Quantum Dot and Mini LED. The former uses a quantum-dot screen with blue LEDs rather than white LEDs and ‘nanocrystals’ of various sizes to convert light into different colours by altering its wavelength. Several TV manufacturers have jumped onboard Quantum Dot technology, but the most popular has been Samsung’s QLED branded TVs.

Mini LED is another derivation of LED LCD panels, employing smaller-sized LEDs that can emit more light than standard versions, increasing brightness output of the TV. And as they are smaller, more can be fitted into a screen, leading to greater control over brightness and contrast. This type of TV is becoming more popular, though in the UK and Europe it’s still relatively expensive. You can read more about Mini LED and its advantages in our explainer.

OLED, meanwhile, hasn’t stood still either. LG is the biggest manufacturer of large-sized OLED panels and has produced panels branded as evo OLED that are brighter than older versions. It uses a different material for its blue OLED material layer within the panel (deuterium), which can last for longer and can have more electrical current passed through it, increasing the brightness of the screen, and elevating the colour volume (range of colours it can display).

Another development is the eagerly anticipated QD-OLED. This display technology merges Quantum Dot backlights with an OLED panel, increasing the brightness, colour accuracy and volume, while retaining OLED’s perfect blacks, infinite contrast and potentially even wider viewing angles, so viewers can spread out anywhere in a room and see pretty much the same image. Samsung and Sonyare the two companies launching QD-OLED TVs in 2022.

And for smartphones there’s been a move towards AMOLED (Active-Matrix Organic Light Emitting Diode) screens for Android screens, while Apple has moved towards OLED for its smartphones and tried Mini LED with its iPad Pro. Technologies are consistently evolving with Superand Dynamic AMOLED versions available, more performance is being eked out.

While LED LCD has been around for much longer and is cheaper to make, manufacturers are beginning to move away from it, at least in the sense of the ‘standard’ LCD LED displays, opting to explore the likes of Mini LED and Quantum Dot variations.

OLED has gained momentum and become cheaper, with prices dipping well below the £1000 price point. OLED is much better than LED LCD at handling darkness and lighting precision, and offers much wider viewing angles, which is great for when large groups of people are watching TV. Refresh rates and motion processing are also better with OLED though there is the spectre of image retention.

If you’re dealing with a limited budget, whether you’re buying a phone, a monitor, a laptop or a TV, you’ll almost certainly end up with an LCD-based screen. OLED, meanwhile, incurs more of a premium but is getting cheaper, appearing in handheld gaming devices, laptops, some of the best smartphones as well as TVs

Which is better? Even if you eliminate money from the equation, it really comes down to personal taste. Neither OLED nor LCD LED is perfect. Some extol OLED’s skill in handling darkness, and its lighting precision. Others prefer LCD’s ability to go brighter and maintain colours at bright levels.

How do you decide? Stop reading this and go to a shop to check it out for yourself. While a shop floor isn’t the best environment in which to evaluate ultimate picture quality, it will at least provide an opportunity for you to realise your priorities. Whether you choose to side with LCD or OLED, you can take comfort in the fact that both technologies have matured considerably, making this is a safe time to invest.

LED-vs-LCD? Lately, choosing a TV has become like walking into a candy store. There are so many TV technology options to choose from, and each of them seems just as good.

Then there are the technical terms to deal with, such as LED TV, LCD TV, QLED TV, UHD TV, OLED TV, and more. You might feel like you need to be a tech pro just to watch your favourite TV show in the evening or enjoy a game with your friend.

Here at Dynamo LED, we offer both LED and LCD TVs, and we appreciate the benefits of both TVs. Be sure to check out our buying an LED Display guide for more info.

First, an important thing to understand is that the LED (Light Emitting Diode) monitor is an improvised version of the LCD (Liquid Crystal Display). This is why all LED monitor is LCD in nature, but not all LCDs are LED monitors.

LCD technology revolutionized monitors by using cold cathode fluorescent lamps for backlighting to create the picture displayed on the screen. A cold cathode fluorescent lamp (CCFL) is a tiny fluorescent bulb. In the context of this article, LCDs refer to this traditional type of CCFL LCD TVs.

Since LEDs replace fluorescent bulbs with light-emitting diodes, LED TVs are more energy-efficient than LCDs. A 32-inch LED TV screen consumes 10 watts less power than the same size LCD screen. The difference in power consumption increases as the size of the display increases.

Light-emitting diodes are considerably smaller than fluorescent lamps used in LCD monitors. Fluorescent lamps have a considerable thickness, but the thickness of diodes is next to none. Moreover, countless diodes are assembled in the same plane, so the thickness of the array isn’t increased no matter how many diodes are present.

Edge-lit LEDs have a slight drawback in viewing angle compared to LCDs, because of the position of the light source. However, direct-view LEDs offer a better angle for viewing than LCDs as the light source is evenly spread on the screen.

This is the time it takes to shift from one colour to another. Response times are generally measured in milliseconds (ms). The shorter the time to respond, the better the quality of the images produced.

Since LED displays use full-array LED backlighting rather than one big backlight, LED TVs offer significantly better contrast than LCDs. LCD backlighting technology only shows white and black, but LED backlighting can emit the entire RGB spectrum, thereby providing a deeper RGB contrast.

If you wonder which display will last longer, this debate is also won by LED displays. LED televisions have a longer lifespan of 100,000 hours on average, compared to 50,000 hours provided by LCD televisions.

An LED display provides the option to dim the backlight, along with other eye comfort features. Not only that, it provides a wider viewing angle without harming image quality. Therefore, an LED display is far better for your eyes than an LCD.

In an LED display, a lot of smaller diodes are used and if a diode is damaged, it can be replaced. In an LCD, you will need to replace the entire bulb in case of damage. Therefore, an LED display is easier and cheaper to maintain than an LCD.

Since LEDs are a better and newer technology, the price of an LED display is higher than an LCD. However, this is only when we are considering the purchase cost.

The picture quality of an LED display is far better than an LCD. Due to modular light-emitting diodes, an LED screen produces better control over the contrast, rendering a clear picture. Also, LED provides RGB contrast, which can show truer blacks and truer whites.

Not to forget, they provide a shorter response time as well. Both of these factors result inLED displays having a better picture quality compared to LCD displays.

Since LED displays are considerably thinner than LCDs, they weigh considerably less. On average, an LED screen weighs about half of an LCD screen of the same size.

As you might have noticed by now, LED wins the battle with LCD without any doubt. This is because LED displays have an advantage in all the factors that matter when considering a purchase, except price.

They are more attractive too. With the increasing shortage of space in new residential complexes, what better solution than an ultra-thin LED display giving a cinematic experience in the comfort of your home.

LED screens are the first choice among the public today, across generations. All are opting to switch to LED from LCD to make their lives more enjoyable and better.

Recently, it was reported that due to the short supply of LCD glass panels, JDF increased the price by 5-10$ in October, with the highest price increase of 10%, which was higher than market expectations. It is expected that glass panel suppliers such as QC and AUO will also increase prices according to the market.

In the new development, Samsung and LGD withdrew from LCD production, and BOE became the global leader and gained the right to speak. This wave of panel market conditions is strong with the demand for home managers’ terminals such as TVs, laptops, and tablets. During the epidemic, prices have risen rapidly. Customers are requested to prepare for stocking as soon as possible to reduce losses！

Sometimes the distance between good and great seems like hardly any distance at all — such as liquid crystal displays (LCDs) versus light-emitting diode (LED) displays. Both are suitable for retail window signage, campus wayfinding or large video walls. But LCD and LED have significant differences, and their specific benefits are worth understanding so you can choose the best displays for your business needs.

LCD is the broader category; LED is a subset. In other words, all LED displays are LCDs, but not all LCDs are LED. LCDs are made up of hundreds of thousands — even millions — of individual pixels built from liquid crystals. Each pixel is capable of displaying a color when it receives an electrical charge. Like a mosaic, the displayed image is built from tiny elements that combine to form the overall picture.

But the liquid crystals don’t produce any light of their own, so in order for the image to be illuminated, the liquid crystals need to be backlit. LCDs are illuminated by cold cathode fluorescent lamps (CCFLs), evenly positioned behind the pixels so that, at least in theory, every part of the screen is evenly lit and at consistent brightness.

Up to a point, LED displays are much the same. An LED screen also uses liquid crystals to generate color — or pure black (no color), by not charging a specific pixel. So LED displays have the same need for backlighting. But rather than CCFL, tiny individual lights (light-emitting diodes) illuminate the liquid crystals.

The individual LEDs can be arranged one of two ways: full-array or edge-lit. For edge lighting, the LEDs are arranged around the edges of the back of the screen. Full-array, on the other hand, calls for many LEDs to be lined up evenly across the back of the screen, where they can be arranged into zones (usually called “dimming zones” or “local dimming”).

Is LED just plain better than LCD? Well, for a while, LCD screens represented the cutting edge of digital signage. But now, about the only meaningful advantage of LCD over LED is price point. As LCD is becoming outdated, it tends to be less of an upfront investment. In every other respect, though, LED displays have the advantage.

No matter the arrangement of the backlighting, LED has a greater nit value than LCD, which means it’s brighter (“nit” comes from the Latin “nitere,” meaning “to shine”). The average nit value for LCDs is between 500 and 700 nits, while LEDs are typically between 1,200 and 2,400 nits. With greater brightness comes greater contrast, and all-day visibility on outdoor displays.

Despite the energy output, higher brightness doesn’t necessarily mean a shorter lifespan. In fact, LED displays have an average lifespan of 10 years — double the average five-year lifespan of LCDs. Factoring longevity into the cost of your signage, LED’s longer lifespan can make it cheaper than LCD in the long run.

Even with edge lighting, LED produces more vividly lifelike images than CCFL-backlit LCDs — and with sleeker hardware, thanks to their minimalist design. And while LCD bezels have drastically reduced over time, they’re still greater than zero. LED has no bezels at all.

Up to 40 times smaller than regular LEDs, microLEDs allow backlighting to be even more precisely targeted, with many times more diodes. This, in turn, delivers a more accurate picture, with greater contrast and highly focused areas of brightness. Samsung’s The Wall is a spectacular example of what microLED is capable of.

Whether you need your digital signage to entertain, inform or simply impress, understanding the differences between LCD and LED will allow you to make a better-informed decision.

From panel technology to refresh rates, there are a lot of things to consider when looking for a new gaming monitor. To aid you on your journey for the perfect setup, we"re breaking down two of the most common display technology terms: LED and LCD. Here"s what you need to know about LED and LCD screens, what the terms stand for, and how they factor into modern gaming monitors.

LCD stands for liquid-crystal display, which refers to how the monitor works. Behind the screen, liquid crystals are sandwiched between two layers of glass and used to change the colors of pixels to create the images that you see. The whole process is a lot more complicated, but that"s the gist of how LCDs function.

In the past, some LCDs were backlit by CCFLs (cold-cathode fluorescent lamps). LCDs with fluorescent backlighting have been around longer, so if you can find one, they will be cheaper than LED monitors. However, if you"re a gamer looking for decent refresh rates and response times, it"s going to be hard to find a monitor with fluorescent backlighting. They"ve almost completely been replaced by LCD monitors with LED backlights.

LEDs work in a similar way; in fact, you can consider LEDs a subcategory of LCDs. The only difference between some LCDs and LEDs is the type of backlighting: LEDs use LED (light-emitting diodes) backlighting.

In contrast to fluorescent backlighting, LED backlighting generally provides brighter colors and sharper contrast. The monitors are also thinner in size and, in the long run, more energy efficient than LCDs with fluorescent backlights. LED backlighting is the newer technology and the current standard for monitors with high refresh rates and fast response times. When you see LCD in product descriptions, they"re almost always LCD monitors that use LED (as opposed to fluorescent) backlighting. For example, BenQ"s EL2870U monitor is listed as an LCD, but it"s an LCD with LED backlighting.

There are different types of LED backlighting: edge-lit and array-lit. In edge-lit monitors, the lights are placed around the edges of the monitor. Light guides are then used to diffuse the light evenly across the screen. In array-lit monitors, lights are placed behind the screen in a pattern.

The tricky thing, however, is that it"s pretty much impossible to tell what type of backlight and how many backlights a monitor has based on a typical product description. Some manufacturers will share that info, but generally they won"t unless the backlight setup is a premium feature you"re paying for.

For example, some edge-lit and array-lit LEDs have local dimming capabilities, a feature that can selectively dim certain zones of LED lights. Local dimming improves contrast ratio and provides deeper blacks in dimly lit scenes. These monitors, however, tend to be pricey. Some well-reviewed options include the Samsung Odyssey G7 and Philips Momentum 436M6VBPAB, both of which are edge-lit monitors with partial local dimming capabilities. The Acer Predator X35 is an (expensive) full-array monitor with full local dimming (FALD) capabilities.

You won"t have much of a choice between LED or LCD. Most monitors, regardless of whether they"re marked as LED or LCD, will use LED backlights. LED backlights became the new standard because they allow manufacturers to make thinner, more energy-efficient monitors with better graphics. It"s not worth going out of your way to find an LCD with fluorescent backlighting, unless you really, really hate LED lights.

Which backlights a monitor has isn"t as important as other factors such as panel technology, refresh rates and response time, G-Sync vs. FreeSync, and HDR --those are the characteristics you should pay more attention to when choosing a monitor. If you"re not looking to break the bank, a couple of great LED monitors at excellent price points we can recommend are the Asus VP249QGR, a nice budget 1080p monitor, and Acer XF250Q Cbmiiprx 24.5, a well-reviewed budget 240Hz monitor.

There are plenty of new and confusing terms facing TV shoppers today, but when it comes down to the screen technology itself, there are only two: Nearly every TV sold today is either LCD or OLED.

The biggest between the two is in how they work. With OLED, each pixel provides its own illumination so there"s no separate backlight. With an LCD TV, all of the pixels are illuminated by an LED backlight. That difference leads to all kinds of picture quality effects, some of which favor LCD, but most of which benefit OLED.

LCDs are made by a number of companies across Asia. All current OLED TVs are built by LG Display, though companies like Sony and Vizio buy OLED panels from LG and then use their own electronics and aesthetic design.

So which one is better? Read on for their strengths and weaknesses. In general we"ll be comparing OLED to the best (read: most expensive) LCD has to offer, mainly because there"s no such thing as a cheap OLED TV (yet).

Take this category with a grain of salt. Both TV types are very bright and can look good in even a sunny room, let alone more moderate indoor lighting situations or the dark rooms that make TV images look their best. When it comes down to it, no modern TV could ever be considered "dim."

The better LCDs have local dimming, where parts of the screen can dim independently of others. This isn"t quite as good as per-pixel control because the black areas still aren"t absolutely black, but it"s better than nothing. The best LCDs have full-array local dimming, which provides even finer control over the contrast of what"s onscreen -- but even they can suffer from "blooming," where a bright area spoils the black of an adjacent dark area.

One of the main downsides of LCD TVs is a change in picture quality if you sit away from dead center (as in, off to the sides). How much this matters to you certainly depends on your seating arrangement, but also on how much you love your loved ones.

A few LCDs use in-plane switching (IPS) panels, which have better off-axis picture quality than other kinds of LCDs, but don"t look as good as other LCDs straight on (primarily due to a lower contrast ratio).

OLED doesn"t have the off-axis issue LCDs have; its image looks basically the same, even from extreme angles. So if you have a wide seating area, OLED is the better option.

Nearly all current TVs are HDR compatible, but that"s not the entire story. Just because a TV claims HDR compatibility doesn"t mean it can accurately display HDR content. All OLED TVs have the dynamic range to take advantage of HDR, but lower-priced LCDs, especially those without local-dimming backlights, do not. So if you want to see HDR content it all its dynamic, vibrant beauty, go for OLED or an LCD with local dimming.

In our tests comparing the best new OLED and LCD TVs with HDR games and movies, OLED usually looks better. Its superior contrast and lack of blooming win the day despite LCD"s brightness advantage. In other words LCD TVs can get brighter, especially in full-screen bright scenes and HDR highlights, but none of them can control that illumination as precisely as an OLED TV.

The energy consumption of LCD varies depending on the backlight setting. The lower the backlight, the lower the power consumption. A basic LED LCD with its backlight set low will draw less power than OLED.

LG has said their OLED TVs have a lifespan of 100,000 hours to half brightness, a figure that"s similar to LED LCDs. Generally speaking, all modern TVs are quite reliable.

Does that mean your new LCD or OLED will last for several decades like your parent"s last CRT (like the one pictured). Probably not, but then, why would you want it to? A 42-inch flat panel cost $14,000 in the late 90"s, and now a 65-inch TV with more than 16x the resolution and a million times better contrast ratio costs $1,400. Which is to say, by the time you"ll want/need to replace it, there will be something even better than what"s available now, for less money.

OLED TVs are available in sizes from 48 to 88 inches, but LCD TVs come in smaller and larger sizes than that -- with many more choices in between -- so LCD wins. At the high end of the size scale, however, the biggest "TVs" don"t use either technology.

If you want something even brighter, and don"t mind spending a literal fortune to get it, Samsung, Sony, and LG all sell direct-view LED displays. In most cases these are

You can get 4K resolution, 50-inch LCDs for around $400 -- or half that on sale. It"s going to be a long time before OLEDs are that price, but they have come down considerably.

LCD dominates the market because it"s cheap to manufacture and delivers good enough picture quality for just about everybody. But according to reviews at CNET and elsewhere, OLED wins for overall picture quality, largely due to the incredible contrast ratio. The price difference isn"t as severe as it used to be, and in the mid- to high-end of the market, there are lots of options.

Like most traders, you probably spend your days and nights staring at computer monitors. It makes sense to find out if you are using the right kind of display and what the differences are. LED-backlit displays are what we recommend.

LCD stands for Liquid Crystal Display. Calculators and handheld gaming consoles have been using LCDs for a long time. However, an LCD doesn’t have any light of its own. So you need light to see an LCD screen.

Initially, LCD manufacturers used Cold Cathode Fluorescent Lamps (CCFLs) to solve the problem. However, CCFLs were heavy and energy inefficient. The color brightness was hard to control, and they took a while to warm up.

LED stands for Light Emitting Diode. A pure LED display (as opposed to an LED-backlit LCD display) uses LEDs for each pixel of the image. Due to the high contrast, these displays can be seen from far away. Large-format displays use this technology for concerts and stadiums.

The problem with LED displays is they are too harsh for close viewing. The compromise, especially for monitors where close viewing is critical, was to develop an LCD monitor that’s lit using LEDs.

Early LED-backlit LCD displays used blue LED with yellow phosphorous to create the white light. The problem with this approach was that early LED-backlit LCDs had a blueish hue.

It’s important to mention that some manufacturers also use edge-lit LED technology where the LEDs are not directly in the back of the display, but rather on the side. The edge light is diffused evenly to the screen. Edge-lit LEDs are used in smaller displays like smartphones. This technology is cheaper than direct backlit.

LED-backlit displays use “local dimming” to improve the contrast ratio. Various manufacturers also use Pulse Width Modulation (PWM) and Direct Current (DC) to control the screen brightness. For some users, PWM flickering can be uncomfortable.

More Colors:LED-backlit displays have a wider gamut of colors than CCFL-based displays. When RGB LED technology is used for backlighting, it can provide a wide spectrum of color. Better dimming range provides further contrast ratio refinement.

Slimmer and Lighter: LED-backlit monitors are significantly slimmer and lighter than CCFL technology. The smaller size and weight makes LED backlit displays great for wall mounting. They also take up less space in a work environment which make them ideal for use with multi-monitor trading computers.

Environment-Friendly:CCFL technology uses mercury, whereas LEDs don’t. So LED-backlit displays are more recycle-friendly. Also, their longer life and smaller size decreases waste in our landfills.

OLED (Organic Light Emitting Diode) is the newest screen technology. It is a direct competitor to LED backlit displays. OLED is brighter, more efficient, and thinner than LED. In fact, they are so thin some models are curved.

OLED monitors generate their own light. The primary downside right now is that OLEDs are way more expensive and not as widely available as LED-backlit. Currently, OLEDs are priced at over $1000 each, although prices are coming down already and will continue to come down, like any new technology.

Another big drawback is that OLED monitors are much more susceptible to image retention (burn-in). Each pixel is driven independently, and the ones that get used the most (like tool bars) will begin to dim before those that aren’t used as much. As technology improves, this is expected to be less of a problem.

LED-backlit displays will continue to provide the best value for traders in the foreseeable future. While it can be tempting to always buy the latest and greatest, even gaming experts aren’t yet recommending OLED.

LCD display screens are everywhere. You probably own one or more devices with an LCD display screen at home and at work. This includes your TV, computer monitor, watches, clocks, smartphones, and even calculators.

But have you ever wondered about how your LCD display screen works, its lifespan, components, and how it holds up to other emerging display technologies today?

Knowing all these things about your LCD display lets you appreciate your screen all the more. Caring for your device becomes easier when you’re armed with this knowledge.

LCD display screens make use of Liquid Crystal Display technology. The screen is embedded with liquid crystals, a substance that has properties in between a conventional liquid and a solid crystal. Liquid crystals can flow, but their molecules carry a crystal-like solid orientation.

Liquid crystals are responsible for producing an image flashed onto the LCD screen. They don’t emit light, though. Backlights are used to illuminate these crystals.

Now, in LCD displays, pixels are regulated by using liquid crystals for rotating polarized light. Polarized light denotes light waves with vibrations occurring in a single plane. In LCDs, this is achieved by using polarized layers.

Each pixel has polarizing filters on both its front and back. Tiny nematic (twisted) liquid crystals are placed in between these filters. The liquid crystals can be switched on or off electronically through tiny electronic transistors.

A single LCD contains millions of pixels, nematic liquid crystals, polarizing filters, and transistors. They all work together to create images on the screen.

Most LCD monitors have a lifespan ranging from 30,000 to 60,000 hours. That’s equivalent to 5-7 years using the monitor for 24 hours per day. It could also translate to 10-20 years with running the monitor for 8 hours a day, 5 days a week.

The backlight’s life expectancy is the biggest factor in determining the LCD display lifespan. It’s because liquid crystals do not give off light from themselves. The liquid crystals depend on the backlight for illuminating them. Hence, the LCD screen wears off when the backlights dim as it reaches its maximum lifespan.

The backlight serves as the illuminator of the entire LCD display device. Without a backlight, the LCD device remains darkened and hard to use. Backlights are installed directly behind the LCD panel to lighten up the display.

Simple devices such as pocket calculators don’t use a backlight for their LCD screens. Users rely on natural light to see the numbers displayed on such calculators. However, the majority of modern LCD screens such as televisions, computer monitors, smartphones, aviation screen panels, outdoor signages, and medical monitoring devices use backlights as their internal light source.

This type of backlight is the most popular and widely-used light source for LCDs today. Light-emitting diodes are semiconductors that emit light once electric current flows into it. Particles carrying the electric current are called electrons holes. These combine with electrons in the semiconductor, releasing photons (light particles).

Edge-Lit White LED (EL-WLED)– One or more LED rows are placed on the screen’s edge. A special light diffuser is used to scatter the light evenly across the entire display screen. Computer monitors, laptops, notebooks, and even HDTVs are now lit in this way.

White LED (WLED)– The LCD panel’s rear side is lit up with several white-colored LEDs. A diffuser is set in front of the LEDs to help evenly smooth out the light throughout the screen. Some computer monitors and large-screen LCD TVs use this LED technology.

Red-Green-Blue LED (RGB LED)– This technology works like WLED. The difference is that it uses red, green, and blue LED combination lights instead of white lights. Better picture quality and higher color gamut are its advantages over WLED and EL-WLED.

ELP uses electroluminescent materials such as colored phosphors instead of heat to create light. This material is placed in between two conductor layers. The material emits light as a result of an electric current flowing through it. ELPs are mostly used in small LCD screens.

HCFL backlights have filaments that need to be heated to excite mercury atoms, cause the current to flow, and ultimately emit light. HCFLs are often used in LCD equipment such as medical devices, custom task-oriented lamps, scanners, and outdoor LCD signs.

Liquid crystals are the heart of an LCD display. This unique substance flows like a liquid but retains many characteristics of solid crystals. They have long and cylindrical-shaped molecules that can twist when changes in molecular orientation happen.

Different liquid crystal families are used in LCD displays. One requirement of such liquids is to exhibit mutual attraction. Also, the molecules in the liquid crystal need to be anisotropic. This means that the liquid crystal molecules have that average structural order along a molecular axis.

Liquid crystals are often sandwiched in between the color filters and the polarizers. They twist and straighten in response to electrical currents applied to them. The movement of liquid crystals controls whether polarized light will pass through the filters or not.

The nematic phase is characterized by the crystal molecules freely moving around the liquid. However, these molecules point themselves to one direction only, making it unique from pure liquid molecules. Nematic liquid crystals are the most common liquid used in LCD screens.

In the smectic phase, the liquid crystals keep their similar orientation and direction. But the molecules are now lining themselves into layers. The smectic layers have restricted movement, creating a solid-like state in the liquid crystals.

Now, molecules in liquid crystals move as a reaction to an electric field. Their arrangement changes as a voltage are applied to them. This allows liquid crystals to control polarized light, which, in turn, defines which pixels on a screen will be illuminated or not.

Color filters are found in between the liquid crystals. These filters determine whether the pixel shows red, green, or blue colors when activated. The filters work by independently controlling the pixel’s red, green, and blue sub-pixels. With this, the LCD screen can reproduce all possible colors found in the color space.

The color filters aren’t active elements, though. It’s the liquid crystal molecules that control the light passing through the filters. The color filters simply determine the color the pixel shows based on how much light is passing through them, as determined by the applied electric voltage and the movement of the liquid crystal molecules.

An LCD cell is made up of two polarizing filters. They enclose the LCD display and color filters. One polarizing filter is located in front of the backlight and is horizontal in orientation. The other one is found just beneath the pixel in front and is vertical in orientation. Polarizing filters are typically made of transparent crystals or glass substrates.

The role of polarizing filters is to control which light patterns can pass through the LCD screen. Without these filters, visual images generated by the LCD panel will have a poor contrast ratio and an inferior quality image.

Now, light emitted by your panel’s backlight source enters the first horizontal polarizing filter. It then passes through the liquid crystals. The polarized light vibrates vertically if the liquid crystals are in a twisted state. Hence, these light waves can then pass through the second vertical polarizing filter. The pixel on the screen turns on and is illuminated properly.

Meanwhile, if the LCD display is arranged in a straightened way, the horizontal light waves that came from the first polarizing filter will be blocked from entering the vertical polarizing filter. The pixel is then turned off and no light illuminates it.

The two polarizing filters need to be vertical and horizontal in orientation, respectively. If the filters are oriented in the same way (ie; both horizontal or both vertical) will block all the light passing through, displaying nothing on the screen.

TFTs are responsible for providing electrical voltage to the LCD display. Each screen pixel has a corresponding transistor, enabling the pixels to easily be controlled in unison through changes in electrical current.

Using TFTs requires less charge and less power to operate the LCD display screen successfully. TFT use also leads to sharper images because each pixel has its own transistor controlling it. The charge given to a certain pixel can be actively maintained even if the screen is refreshed to display another image.

That’s all the basic information you need to know about LCD display screens. Now, you know how an LCD screen works, its possible lifespan, its components, and how it compares to other display technologies.

Armed with this information, you can better appreciate and take care of your LCD display devices. And in case you’re planning to add display devices to your business, the information you’ve learned will help you make educated choices regarding the display technologies you’ll utilize.
