what does an lcd screen look like in stock

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.

Although newer and more efficient apps now use widget-styled interfaces, your best bet could be a singular, large monitor with a QHD or UHD resolution. In any case, the wide market can provide you with a specific solution which should fit your budget and satisfy your meticulous requirements.

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.

If you can only envision two or three monitors, you can follow our guide to affordable accessories here. This guide describes and recommends the best and most affordable mounts and cables you will ever need to start a basic stock trading setup.

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 next step is choosing acceptable models from the plethora of monitors being sold. We recommend users to get IPS-equipped models so you won’t have to deal with color shifts and poor viewing angles. We also recommend 22-inch to 24-inch models with a 1080p resolution since the recommended mount can only hold such.

The AOC I2369VM is one of the cheapest 23-inch monitors with IPS panels available in the market today. Despite fitting the budget category of monitors, this model utilizes a slim design with a three-sided bezel-free face making it suitable for side by side placement. Also, the matte silver finish gives it a sophisticated look which further emphasizes on its business-class nature.

The IPS panel in the AOC I2369VM is capable of excellent contrast ratio, gamma, and panel uniformity ensuring your work is visibly clear and precise even if viewed at an off angle. You also get a pixel response time of 5ms, so you need not worry about ghosting or interlacing while your programs continually update their content.

The Asus VC239H is one of the most globally popular IPS monitors around the world for its excellent value and build quality. Asus designed the VC239H with the infinity-edge concept they use on their high-end models, so you won’t see any bezels on the top and of the sides of the screen.

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.

Dell is a staple brand when considering professional or business monitors for their outstanding reliability, performance, and sophisticated design. The Dell S2415H is one such model who embodies these qualities, despite having an awesomely affordable price. Clad in the company’s signature matte black and silver cabinets, this borderless display will look fantastic on the mount we specified.

Of course, this model also includes an IPS panel for excellent clarity and viewing angles. Using the Multimedia preset enables lush colors and correct saturation levels. This out of the box performance is excellent for easily building your command center with multiple monitors for stock trading,

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.

For this category, we recommend users to get either a large 4K display or a stunning ultra-wide monitor with a UW-QHD resolution so you can maximize your virtual viewing space for your widgets and apps.

The Dell P43127Q is one of the most specialized monitors for stock trading because it is a multi-client display. The massive 43-inch screen with a 4K panel can split into four different sections with 1080p resolutions each, giving users a simulated quad monitor experience for unrivaled efficiency.

You can utilize several host devices to stream multiple sources in the Dell P4317Q, or you can utilize the massive viewing space to open your widgets and designate them to a side or quadrant freely. The gorgeous 10-bit IPS panel can display near perfect coverage of the sRGB gamut, and panel uniformity is excellent for something so big.

Another excellent behemoth is the Philips BDM4350UC, a 43-inch professional monitor with an IPS panel. This model almost looks like your 4K TV in the living room with thin bezels, making it look like a gorgeous centerpiece for your office or workspace. Just like the Del P4317Q above, this screen can also serve as a multi-client device. The 4K resolution of the big screen also enables you to open multiple apps and widgets simultaneously, ensuring your workflow is efficient.

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.

If you want something bigger and better than the previous entry, the next best thing is the LG 38UC99 which has a whopping 3840 x 1600 resolution which is enough to display three or four windows side by side. Like most of LG’s high-end monitors, the 38UC99 is able to output 99% sRGB coverage for excellent vibrancy and accuracy.

You can maximize the vast viewing space with the help of LG Screen Split 2.0, plus you can enjoy a bit of gaming with its 75Hz refresh rate which is complemented by AMD Freesync for image stability and tear-free enjoyment. The LG38UC99 is also big on features since it is equipped with a plethora of image-enhancing options and a multitude of connection ports which include the future-proof USB-C for charging and harnessing audio/video signals from a compatible device.

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.

In its first press release that addressed Muddy Waters Research’ allegations, Focus Media’s (NASDAQ:FMCN) clarified the LCD screens, which include Basic LCD, LCD 2.0 digital screen, and LCD 1.0 picture frames. See table from the press release:

Muddy Waters then published a second report, featuring a transcript of the conversation between Muddy Waters and a Focus Media sales manager in which the sales manager “confirmed” Muddy Waters’ assertion that Focus Media overstated its LCD screens.

On the same day, Focus Media published its second press release, further clarifying the different LCD devices to inform the investors that they are not double counting the number of digital poster frames into the LCD network.

From my observation, the confusion behind the “double counting” of LCD screens can be attributed to the company’s acquisition of Framedia in 2005. Framedia was once Focus Media’s competitor and dominated the in-elevator poster frame advertising market with its digital and traditional poster frames. After the acquisition, Focus Media consolidated its own LCD, digital frame, and traditional picture frame under the “LCD network” to distinguish the “Focus Media” branded screens from those of Framedia.

Intuitively, the newly acquired Framedia network was designated Focus Media’s “Poster Frame Network” since Framedia’s digital and non-digital poster frames outnumbers those of Focus Media by almost 7 times, according to its Q3 result and the company’s first press release.

According to Focus Media’s second press release: As of September 30, 2011, the 178,382 display devices in the LCD display network included: 116,026 LCD screens, 32,478 LCD 2.0 digital picture screensand 29,878 LCD 1.0 picture frame devices. Both the LCD screens and LCD 2.0 digital picture screens have the technical capacity to show video images as well as dynamic and static images, whereas the 1.0 picture frame devices that are part of the LCD display network only display traditional fixed images.

LCD 2.0 digital frame is the digital poster frame under the “Focus Media” brand. Like the LCD screen, it is capable of playing video, flash, and static ads. (Note the circled “Focus Media” brand.)

In the same press release, poster frame network is defined as: The Company"s poster frame network, which is distinct from its LCD display network, consists of traditional and digital advertising poster frames placed mainly in the elevators and public areas of residential complexes which it markets under the brand name Framedia.

Note the “Framedia” logo on the top left corner of the digital poster frame. The most recent definition of LCD and Poster Frame Network is different from those in the previous 20-F filings. From Focus Media’s 2010 20-F filing, page 38: Our LCD display network, which refers to our network of flat-panel television displays placed in high-traffic areas of commercial and public buildings marketed to advertisers as a network or as seven separate channels targeting different types of consumers—our premier A and B office building channels, travel, fashion, elite and IT mall channels.

And on page 39, regarding poster frames: We own and operate a network of traditional and digital advertising poster frames deployed primarily in the elevators and public areas of residential complexes under the brand name ‘Framedia.’ ... As of December 31, 2010, we had installed 300,012 poster frames including 35,810 digital poster frames in cities throughout China. Our digital frames use high-resolution LCD displays with integrated sound, all-angle viewing and remote control technologies. Our advertising posters include both traditional printed posters as well as digital LCD poster frames with integrated sound, all-angle and remote control technologies placed in elevators and public areas in residential complexes and commercial locations.

However, I would like to point out that Focus Media has improved its transparency as the company’s audit committee is completing its engagement of two reputable independent survey firms to conduct a comprehensive survey of its LCD network.

I expect the company will have the result of the survey within the next three weeks. In addition, I am encouraged to see that Focus Media will begin to provide investors with the expanded screen count format that specifies the number of screens in each segment going forward for its press releases and earnings announcements.

On a final note, I believe that the company needs to better educate and communicate with its sales force in regards to the different types of LCD screens. While Focus Media breaks down the LCD network into Basic LCD, LCD 2.0 digital frame, and LCD 1.0 picture frame at the corporate level, my channel check indicates that the sales managers at the local level designate Basic LCD screens as “LCD network” and categorize both the LCD 2.0 digital frames and the LCD 1.0 picture frames as the Framedia screens, potentially inflating the screens in the Poster Frame Network while understating the screens in the LCD Network.

Through my conversation with the sale managers, some even classified the screens as “horizontal LCD screens,” which are the Basic LCD screens, “vertical LCD displays,” which contain both LCD 2.0 digital screens and Framedia’s digital screens, and “vertical wooden display,” which contain both LCD 1.0 picture frame and Framedia’s non-digital screens.

This misconception is consistent among the sales managers I called during the past week. In the wake of this incident, I hope that Focus Media can better educate its sales force so this kind of misunderstanding can be prevented in the future.

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."

At the other side of light output is black level, or how dark the TV can get. OLED wins here because of its ability to turn off individual pixels completely. It can produce truly perfect black.

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.

Here"s where it comes together. Contrast ratio is the difference between the brightest and the darkest a TV can be. OLED is the winner here because it can get extremely bright, plus it can produce absolute black with no blooming. It has the best contrast ratio of any modern display.

Contrast ratio is the most important aspect of picture quality. A high contrast-ratio display will look more realistic than one with a lower contrast ratio.

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.

OLED"s energy consumption is directly related to screen brightness. The brighter the screen, the more power it draws. It even varies with content. A dark movie will require less power than a hockey game or ski competition.

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.

As often as you use your smartphone, it’s almost inevitable that you’ll eventually drop it. You may be extremely careful, but it only takes one fumble for your phone to tumble. While iPhone screens are designed to withstand impact, you might still end up with a shattered screen.

The good news: a broken screen doesn’t mean your phone is kaput. In fact, if only the glass is broken, the fix is quick and inexpensive. The bad news: if the LCD screen is broken, you’re looking at a pricier repair.

If you’ve looked into replacement parts, you’ve likely come across two very different options: a glass screen, and an LCD screen. While the first option is cheap, the second is definitely not. Here’s the difference:

1. The glass screen is the exterior layer on your phone’s display. While it is specially engineered for durability, it’s still just glass (between layers of plastic film), which is why it’s not very pricey to replace.

Most of the time, the damage to your screen will be pretty obvious. You’ll see the spider web patterns of shattered glass across the front of your iPhone. Occasionally, however, the glass screen will be intact, and you might not realize the damage until you try to use it. Whether the damage is visible or not, it’s a good idea to run a quick diagnostic to determine the extent of it.

If you encounter any of these problems, you’re dealing with a broken LCD screen. If the glass is shattered, but the display is clear and touch capability is working, that’s a good sign. The problem is probably just the glass screen.

Whether you’re dealing with cracked glass or a broken LCD screen, you can find a quick, reliable repair service at FastPhoneRepair.com. Our qualified technicians will get your iPhone repaired and up and running again in record time and at reasonable rates.

Every aspect of the light imaging system in Pro Display XDR is crucial to the overall quality of what you see onscreen. Each element builds on top of the last to create a display with unbelievable brightness and contrast.

Typical LCDs are edge-lit by a strip of white LEDs. The 2D backlighting system in Pro Display XDR is unlike any other. It uses a superbright array of 576 blue LEDs that allows for unmatched light control compared with white LEDs. Twelve controllers rapidly modulate each LED so that areas of the screen can be incredibly bright while other areas are incredibly dark. All of this produces an extraordinary contrast that’s the foundation for XDR.

For even greater control of light, each LED is treated with a reflective layer, a highly customized lens, and a geometrically optimized reflector that are all unique to Pro Display XDR. Through a pioneering design, light is reflected, mixed, and shaped between two layers to minimize blooming and provide uniform lighting.

Converting blue light to white is a difficult process that requires extremely precise color conversion. It’s why most display makers use white LEDs. Pro Display XDR accomplishes this conversion with an expertly designed color transformation sheet made of hundreds of layers that control the light spectrum passing through them.

Pro Display XDR extends exceptional image quality to the very edge. To ensure that LEDs along the sides of the display mix well with adjacent ones, a micro-lens array boosts light along the edges. This creates uniform color and brightness across the entire screen.

With a massive amount of processing power, the timing controller (TCON) chip utilizes an algorithm specifically created to analyze and reproduce images. It controls LEDs at over 10 times the refresh rate of the LCD itself, reducing latency and blooming. It’s capable of multiple refresh rates for amazingly smooth playback. Managing both the LED array and LCD pixels, the TCON precisely directs light and color to bring your work to life with stunning accuracy.

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.

Shopping for a new TV is like wading through a never-ending pool of tech jargon, display terminology, and head-spinning acronyms. It was one thing when 4K resolution landed in the homes of consumers, with TV brands touting the new UHD viewing spec as a major marketing grab. But over the last several years, the plot has only continued to thicken when it comes to three- and four-letter acronyms with the introduction of state-of-the-art lighting and screen technology. But between OLEDs, QLEDs, mini-LEDs, and now QD-OLEDs, there’s one battle of words that rests at the core of TV vocabulary: LED versus LCD.

Despite having a different acronym, LED TV is just a specific type of LCD TV, which uses a liquid crystal display (LCD) panel to control where light is displayed on your screen. These panels are typically composed of two sheets of polarizing material with a liquid crystal solution between them. When an electric current passes through the liquid, it causes the crystals to align, so that light can (or can’t) pass through. Think of it as a shutter, either allowing light to pass through or blocking it out.

Since both LED and LCD TVs are based around LCD technology, the question remains: what is the difference? Actually, it’s about what the difference was. Older LCD TVs used cold cathode fluorescent lamps (CCFLs) to provide lighting, whereas LED LCD TVs used an array of smaller, more efficient light-emitting diodes (LEDs) to illuminate the screen.

Since the technology is better, all LCD TVs now use LED lights and are colloquially considered LED TVs. For those interested, we’ll go deeper into backlighting below, or you can move onto the Local Dimming section.

Three basic illumination forms have been used in LCD TVs: CCFL backlighting, full-array LED backlighting, and LED edge lighting. Each of these illumination technologies is different from one another in important ways. Let’s dig into each.

CCFL backlighting is an older, now-abandoned form of display technology in which a series of cold cathode lamps sit across the inside of the TV behind the LCD. The lights illuminate the crystals fairly evenly, which means all regions of the picture will have similar brightness levels. This affects some aspects of picture quality, which we discuss in more detail below. Since CCFLs are larger than LED arrays, CCFL-based LCD TVs are thicker than LED-backlit LCD TVs.

Full-array backlighting swaps the outdated CCFLs for an array of LEDs spanning the back of the screen, comprising zones of LEDs that can be lit or dimmed in a process called local dimming. TVs using full-array LED backlighting to make up a healthy chunk of the high-end LED TV market, and with good reason — with more precise and even illumination, they can create better picture quality than CCFL LCD TVs were ever able to achieve, with better energy efficiency to boot.

Another form of LCD screen illumination is LED edge lighting. As the name implies, edge-lit TVs have LEDs along the edges of a screen. There are a few different configurations, including LEDs along just the bottom, LEDs on the top and bottom, LEDs left and right, and LEDs along all four edges. These different configurations result in picture quality differences, but the overall brightness capabilities still exceed what CCFL LCD TVs could achieve. While there are some drawbacks to edge lighting compared to full-array or direct backlight displays, the upshot is edge lighting that allows manufacturers to make thinner TVs that cost less to manufacture.

To better close the local-dimming quality gap between edge-lit TVs and full-array back-lit TVs, manufacturers like Sony and Samsung developed their own advanced edge lighting forms. Sony’s technology is known as “Slim Backlight Master Drive,” while Samsung has “Infinite Array” employed in its line of QLED TVs. These keep the slim form factor achievable through edge-lit design and local dimming quality more on par with full-array backlighting.

Local dimming is a feature of LED LCD TVs wherein the LED light source behind the LCD is dimmed and illuminated to match what the picture demands. LCDs can’t completely prevent light from passing through, even during dark scenes, so dimming the light source itself aids in creating deeper blacks and more impressive contrast in the picture. This is accomplished by selectively dimming the LEDs when that particular part of the picture — or region — is intended to be dark.

Local dimming helps LED/LCD TVs more closely match the quality of modern OLED displays, which feature better contrast levels by their nature — something CCFL LCD TVs couldn’t do. The quality of local dimming varies depending on which type of backlighting your LCD uses, how many individual zones of backlighting are employed, and the quality of the processing. Here’s an overview of how effective local dimming is on each type of LCD TV.

TVs with full-array backlighting have the most accurate local dimming and therefore tend to offer the best contrast. Since an array of LEDs spans the entire back of the LCD screen, regions can generally be dimmed with more finesse than on edge-lit TVs, and brightness tends to be uniform across the entire screen. Hisense’s impressive U7G TVs are great examples of relatively affordable models that use multiple-zone, full-array backlighting with local dimming.

“Direct local dimming” is essentially the same thing as full-array dimming, just with fewer LEDs spread further apart in the array. However, it’s worth noting that many manufacturers do not differentiate “direct local dimming” from full-array dimming as two separate forms of local dimming. We still feel it’s important to note the difference, as fewer, further-spaced LEDs will not have the same accuracy and consistency as full-array displays.

Because edge lighting employs LEDs positioned on the edge or edges of the screen to project light across the back of the LCD screen, as opposed to coming from directly behind it, it can result in very subtle blocks or bands of lighter pixels within or around areas that should be dark. The local dimming of edge-lit TVs can sometimes result in some murkiness in dark areas compared with full-array LED TVs. It should also be noted that not all LED edge-lit TVs offer local dimming, which is why it is not uncommon to see glowing strips of light at the edges of a TV and less brightness toward the center of the screen.

Since CCFL backlit TVs do not use LEDs, models with this lighting style do not have dimming abilities. Instead, the LCD panel of CCFL LCDs is constantly and evenly illuminated, making a noticeable difference in picture quality compared to LED LCDs. This is especially noticeable in scenes with high contrast, as the dark portions of the picture may appear too bright or washed out. When watching in a well-lit room, it’s easier to ignore or miss the difference, but in a dark room, it will be, well, glaring.

As if it wasn’t already confusing enough, once you begin exploring the world of modern display technology, new acronyms crop up. The two you’ll most commonly find are OLED and QLED.

An OLED display uses a panel of pixel-sized organic compounds that respond to electricity. Since each tiny pixel (millions of which are present in modern displays) can be turned on or off individually, OLED displays are called “emissive” displays (meaning they require no backlight). They offer incredibly deep contrast ratios and better per-pixel accuracy than any other display type on the market.

Because they don’t require a separate light source, OLED displays are also amazingly thin — often just a few millimeters. OLED panels are often found on high-end TVs in place of LED/LCD technology, but that doesn’t mean that LED/LCDs aren’t without their own premium technology.

QLED is a premium tier of LED/LCD TVs from Samsung. Unlike OLED displays, QLED is not a so-called emissive display technology (lights still illuminate QLED pixels from behind). However, QLED TVs feature an updated illumination technology over regular LED LCDs in the form of Quantum Dot material (hence the “Q” in QLED), which raises overall efficiency and brightness. This translates to better, brighter grayscale and color and enhances HDR (High Dynamic Range) abilities.

And now to make things extra confusing, part of Samsung’s 2022 TV lineup is being billed as traditional OLEDs, although a deeper dive will reveal this is actually the company’s first foray into a new panel technology altogether called QD-OLED.

This is usually a rectangular circuit board located near the audio and visual cables. Replace obviously damaged parts using a soldering iron, or order a replacement board and carefully install it to the same screws and ribbon cables.

The main control buttons may be faulty. Clean them with a metal cleaner, or jostle to attach a loose connection. If necessary, locate the circuit board they are attached to and re-solder any broken connections.

Check input cables for damage, or try other cables of the same type. If necessary, inspect the circuit board they are attached to and re-solder damaged connections.
