Flat-panel displays are thin panels of glass or plastic used for electronically displaying text, images, or video. Liquid crystal displays (LCD), OLED (organic light emitting diode) and microLED displays are not quite the same; since LCD uses a liquid crystal that reacts to an electric current blocking light or allowing it to pass through the panel, whereas OLED/microLED displays consist of electroluminescent organic/inorganic materials that generate light when a current is passed through the material. LCD, OLED and microLED displays are driven using LTPS, IGZO, LTPO, and A-Si TFT transistor technologies as their backplane using ITO to supply current to the transistors and in turn to the liquid crystal or electroluminescent material. Segment and passive OLED and LCD displays do not use a backplane but use indium tin oxide (ITO), a transparent conductive material, to pass current to the electroluminescent material or liquid crystal. In LCDs, there is an even layer of liquid crystal throughout the panel whereas an OLED display has the electroluminescent material only where it is meant to light up. OLEDs, LCDs and microLEDs can be made flexible and transparent, but LCDs require a backlight because they cannot emit light on their own like OLEDs and microLEDs.

Liquid-crystal display (or LCD) is a thin, flat panel used for electronically displaying information such as text, images, and moving pictures. They are usually made of glass but they can also be made out of plastic. Some manufacturers make transparent LCD panels and special sequential color segment LCDs that have higher than usual refresh rates and an RGB backlight. The backlight is synchronized with the display so that the colors will show up as needed. The list of LCD manufacturers:

Organic light emitting diode (or OLED displays) is a thin, flat panel made of glass or plastic used for electronically displaying information such as text, images, and moving pictures. OLED panels can also take the shape of a light panel, where red, green and blue light emitting materials are stacked to create a white light panel. OLED displays can also be made transparent and/or flexible and these transparent panels are available on the market and are widely used in smartphones with under-display optical fingerprint sensors. LCD and OLED displays are available in different shapes, the most prominent of which is a circular display, which is used in smartwatches. The list of OLED display manufacturers:

MicroLED displays is an emerging flat-panel display technology consisting of arrays of microscopic LEDs forming the individual pixel elements. Like OLED, microLED offers infinite contrast ratio, but unlike OLED, microLED is immune to screen burn-in, and consumes less power while having higher light output, as it uses LEDs instead of organic electroluminescent materials, The list of MicroLED display manufacturers:

LCDs are made in a glass substrate. For OLED, the substrate can also be plastic. The size of the substrates are specified in generations, with each generation using a larger substrate. For example, a 4th generation substrate is larger in size than a 3rd generation substrate. A larger substrate allows for more panels to be cut from a single substrate, or for larger panels to be made, akin to increasing wafer sizes in the semiconductor industry.

The UN46C7000 LED television brings new depth and dimension to it all— so you’re not just watching the action, you’re living it. Along with a visually stunning picture, it also features web-connected Samsung Apps so you can stream movies, play games, flip through photos, and more while you watch TV. And Real 240Hz Clear Motion Rate virtually eliminates all motion blur so your picture is crisp. Add a 6,000,000:1 Mega Dynamic Contrast Ratio and you’ll experience a truly exceptional home entertainment experience.

To all the advantages of our LED screen like brilliant color, sharp contrast and low energy consumption, add one more. Mercury-free. While conventional LCD TVs contain mercury, our LED TVs have zero, achieved by using a toxic-free LED lamp instead of CCFL. It is even up to 50% more efficient than the latest ENERGY STAR® specifications (depending on series and screen size, in standard mode).

This short summary of the Samsung UN46C7000 TV 116.8 cm (46") Full HD Black data-sheet is auto-generated and uses the product title and the first six key specs.

This is an auto-generated long summary of Samsung UN46C7000 TV 116.8 cm (46") Full HD Black based on the first three specs of the first five spec groups.

Samsung UN46C7000. Display diagonal: 116.8 cm (46"), Display resolution: 1920 x 1080 pixels, HD type: Full HD, Native aspect ratio: 16:9. Product colour: Black

The Samsung UN46C7100 has a wide, sturdy stand with a brushed aluminum finish. It feels heavy enough to secure the large TV panel, and allows the panel to swivel back and forth.

The Samsung UN46C7100 showed a strong performance in our black level test. Though it wasn"t quite as good as the Sony HX800, it was identical to the Samsung C8000. None of these LCD displays could match the plasma Panasonic, which is the norm for televisions. (More on how we test Black Level.)

The Samsung UN46C7100 was a strong performer in the motion tests, as most of the recent Samsung reviews. When we turned the motion processing features off, we saw the normal amount of flickering, trailing, and loss of fine detail, but certainly no more (and maybe even a little less) than most LCDs. (More on how we test Motion.)

The motion artifacting seen on the Samsung UN46C7100 was the same as almost any LCD TV: trailing, flickering, and loss of detail. When the Auto Motion Plus feature is engaged, additional artifacts are created.

All the ports on the Samsung UN46C7100 are located on the back of the TV, in an L-shape. Half face downward, and half face the left side. Because they hug so close to the TV panel getting wires to fit can be tricky. Fortunately, the TV can swivel on its base, making everything a little easier to access.

The Samsung UN46C7100 showed a good, conservative power consumption when we tested it. As an LCD TV, you can raise and lower the backlight to adjust not only the brightness, but the power draw, as well. Our testing results are in the table below. (More on how we test Power Consumption.)

The chart below shows how the Samsung UN46C7100 compares to the competition. Note that the plasma Panasonic requires much more power than the LCD TVs.

The Samsung UN46C8000 is one tier up from the C7000 series in the Samsung LED television line-up. There"s not a whole lot of difference. The C8000 series offers a different type of dynamic contrast processing, but the C7000 has a version, as well.  The C8000 panel sits on a four-legged pedestal rather than a rectangular base. The C8000 is also marginally slimmer than the C7000. Both display 3D. In terms of performance, they"re virtually identical. Take your pick. They"re both great TVs.

The Samsung UN46C7100 performed almost identically to the Samsung UN46C7000 in black level, peak brightness, and contrast ratio. Samsung professes that the C8000 series should have a better contrast ratio, but that"s only due to an active dimming feature that we disable for testing (because it produces skewed results).

The Panasonic TC-P50VT20 is a plasma display, which offers distinct advantages and disadvantages over LCD. The viewing angle is much better, and in this particular TV, we thought the motion performance and 3D experience were the best in its class. However, some people feel that plasma displays don"t appear as sharp as comparably priced LCDs. The TC-P50VT20 also showed a particular weakness in producing a bright enough image. Overall, we would choose the Panasonic if you really plan on taking advantage of the 3D feature, because its performance is more immersive and less prone to crosstalk. Also, if the intended room is wide and shallow, the wider viewing angle will come in handy. For most other purposes, the Samsung is a great TV that looks cool in your living room and has a slightly sharper picture.

The Panasonic, as a plasma display, offers a much deeper black level than the LCD TVs in the comparison pool. However, the peak brightness was particularly weak, which made for an overall disappointing contrast ratio.

There are two models in the C71000 series, which varies only slightly from the C7000 series. The UN46C7100 is upgraded from the UN46C7000 with the additions of two pairs of 3D glasses, an upgraded speaker system, and a LAN port for streaming content and DLNA home networking. Strangely, the larger 55-inch model in the C7000 series does have LAN.

With the view through the right side of the 3D glasses, you can see a more pronounced shadow, which is part of the left frame that is showing through. We tried two pairs of glasses, and the same effect was viewable in both, and it looked pretty much the same, with the right eye seeming to get a quite significant chunk of the frame intended for the left eye, and the left getting a small amount of the right eye"s frame. So, it seems that this might be an endemic problem to this display, which could be caused by either the display not being able to switch between the two images fast enough, or the LCD panels in the glasses not switching at the correct time. We did see a similar issue with the Panasonic TC-P50VT20, but it was much less pronounced: that display seemed to do a much better job of seperating the frames for a more convincing 3D effect. We are continuing to investigate.

Compared to the other 3D HDTV that we have in for review (the Panasonic TC-P50VT20), we found that the advantages of this LCD display over the Panasonic plasma were evident in 3D viewing as well as 2D. The image was brighter and had significantly better detail at the high end of the brightness range: details on bright objects were much better represented on the Samsung LCD screen than the Panasonic Plasma. However, the Samsung LCD screen had weaker blacks, with the blacks looking much brighter than the Panasonic Plasma. This meant that more dramatic sequences lacked the impact of the plasma screen. Plus, the LCD screen also had some issues with handling deep blacks. On one section of footage where a title box was overlaid on a black screen, the edges of the box were clearly visible, an effect that was not visible on the Panasonic. We"ll be doing more testing in the next few days, but from our initial testing, it looks like the advantages of LCD screens are carrying over into the 3D world from the 2D one.

The Samsung UN55C7000 is a 3D HDTV, but it doesn"t come with any 3D glasses. To start enjoying 3D, you will need to buy the glasses separately at a cost of $150 each, or $350 for a 3D Starter Kit that includes 2 sets and a 3D Blu-ray disc of Monsters Vs Aliens. The glasses themselves (model number SSG-2100AB) are active shutter ones: each eye is covered by an LCD panel that flickers between on and off in response to a signal sent by an IR emitter on the front of the screen.

The glasses are smaller than the ones that come with the Panasonic TC-P50VT20, and they feel a little more comfortable to wear, pressing down less on the nose. They also cover less of the face, but you definitely don"t forget that you are wearing them. Unlike the Panasonic 3D glasses, they are not adjustable. The glasses are powered by a single CR3 watch battery located under a panel on the left arm. You switch them on by pressing a button on the top of the right arm: the glasses then start looking for the signal sent by the TV. If they don"t detect it within a few minutes, they turn themselves off.

We measured the TV"s viewing angle at 44°. That means, once you get about 22° off center, you"ll only see about 50% of the TV"s maximum contrast ratio. This is an average viewing angle for an LCD HDTV, since the display technology really can"t offer a particularly wide viewing angle. Plasmas, on the other hand, can offer a viewing angle that"s almost a full 180°.

The best way to control power consumption on an LCD television is by tinkering with the backlight control. For best performance, we turn the backlight all the way up to maximum (a setting of 20, in this case). For the final score in this section, however, we lower the backlight until the whites are peaking at approximately 200 cd/m2^ (which equaled a backlight setting of 12 on this Samsung).

A promotional image of a quantum-dot LED TV (Samsung Electronics)Samsung Display, the display making arm of Samsung Electronics, is poised to fully shut down its unprofitable liquid crystal display panel business for televisions in June, after over 30 years of operation.

“(Samsung Display) will terminate its supply of LCD panels in June,” an industry source said Monday. The company has been manufacturing its lower-end panels in Asan, South Chungcheong Province.

The long-awaited move came as LCD TV panel prices have been on a constant decline. This led to greater losses for Samsung Display, while Chinese competitors have been ramping up their dominance in the global industry supported by state subsidies and tax breaks.

LCD TVs are considered lower-end when compared to those using cutting-edge TV components such as organic light-emitting diode panels and quantum dot display panels.

According to market intelligence firm Omdia‘s estimate compiled by Daishin Securities, 43-inch LCD panel prices fell 46 percent from September 2021 to May this year, while that of 55-inch panels and 65-inch panels both declined 34 percent over the cited period.

This marks the end of Samsung’s three-decade LCD TV panel business. Once the largest LCD TV panel supplier in the world, Samsung Display‘s market share has gradually shrunk from 22 percent in 2014 to around 2 percent this year.

Samsung Display had sought to exit the business from before 2021, but has been hanging on in part due to Samsung Electronics’ LCD panel supply shortage.

Choi Kwon-young, executive vice president of Samsung Display, confirmed the company’s full exit from the LCD TV panel business within this year in a first-quarter conference call in April.

Given that Samsung’s LCD TV panel exit has long been anticipated and carried out gradually, Samsung Electronics will “unlikely be affected by Samsung Display‘s LCD panel exit” in terms of its continuity in the LCD TV set business, noted Kim Hyun-soo, an analyst at Hana Financial Investment on Monday.

Samsung looks to pivot to quantum dot display technologies for its TV panel business, using quantum dot light-emitting diodes or quantum dot organic light-emitting diodes.

As for the anticipated collaboration between TV maker Samsung Electronics and the world‘s sole white-OLED TV panel supplier LG Display, Kim of Hana said the launch of Samsung’s OLED TV is unlikely within this year due to prolonged negotiations.

Samsung Display will stop producing LCD panels by the end of the year. The display maker currently runs two LCD production lines in South Korea and two in China, according to Reuters. Samsung tells The Verge that the decision will accelerate the company’s move towards quantum dot displays, while ZDNetreports that its future quantum dot TVs will use OLED rather than LCD panels.

The decision comes as LCD panel prices are said to be falling worldwide. Last year, Nikkei reported that Chinese competitors are ramping up production of LCD screens, even as demand for TVs weakens globally. Samsung Display isn’t the only manufacturer to have closed down LCD production lines. LG Display announced it would be ending LCD production in South Korea by the end of the 2020 as well.

Last October Samsung Display announced a five-year 13.1 trillion won (around $10.7 billion) investment in quantum dot technology for its upcoming TVs, as it shifts production away from LCDs. However, Samsung’s existing quantum dot or QLED TVs still use LCD panels behind their quantum dot layer. Samsung is also working on developing self-emissive quantum-dot diodes, which would remove the need for a separate layer.

Samsung’s investment in OLED TVs has also been reported by The Elec. The company is no stranger to OLED technology for handhelds, but it exited the large OLED panel market half a decade ago, allowing rival LG Display to dominate ever since.

Although Samsung Display says that it will be able to continue supplying its existing LCD orders through the end of the year, there are questions about what Samsung Electronics, the largest TV manufacturer in the world, will use in its LCD TVs going forward. Samsung told The Vergethat it does not expect the shutdown to affect its LCD-based QLED TV lineup. So for the near-term, nothing changes.

One alternative is that Samsung buys its LCD panels from suppliers like TCL-owned CSOT and AUO, which already supply panels for Samsung TVs. Last year The Elec reported that Samsung could close all its South Korean LCD production lines, and make up the difference with panels bought from Chinese manufacturers like CSOT, which Samsung Display has invested in.

samsung un46c7000 3d tv also features a swivel stand, has an Ultra Slim, Touch of Colour design and Mega Dynamic Contrast for the most vibrant colours.

At around $2300 this the 46C7000 is on the pricey upper end of the 46" options scale – justified somewhat by the scaled up features set. There are few plasma options in this size category so LCD is it. Competition hails from the picture quality focused Sony XBR-46HX900, the local dimming 240Hz/480Hz LG 47LE8500, and the super thin Sharp 46LE820UN. 3D compatibility is a feature present in this model that commands attention and will likely be highly desirable for the early adapter set. But it would not surprise me to see the price on this TV drop later in 2010.

In 1991, a business unit called Samsung Display was formed to produce the panels used in products made by its parent company, Samsung Electronics. Afterward, it was a leading supplier of LCD panels not just for Samsung Electronics but for other companies in the industry as well.

The business received a stay of execution when the pandemic led to a global surge in demand for consumer electronics, but that demand is now declining, and projections aren"t good for LCD panel revenue.

Add to that the fact that emerging technologies like QD-OLED are the future for TV and monitors, and the case for keeping Samsung Display"s LCD business going becomes a hard one to make.

Samsung Display will now focus heavily on OLED and quantum dot. Most of the employees working in the LCD business will move to quantum dot, the publication claims.

Even if there isn"t a statement about a change in direction, the writing has been on the wall for Samsung"s LCD business. Unless something radical changes, it"s more a question of when than if at this point.
