There are various panel technologies. Each has its own specific features - viewing angles, color reproduction, response time, brightness/contrast, production cost, etc. The image quality depends directly on the type of the display panel used.IPS

The most widely used panels are those with 6, 8, and 10 bits for each of the RGB components of the pixel. They provide 18-, 24-, and 30-bit color, respectively.10 bits (8 bits + FRC)

Frame Rate Control (FRC) is a method, which allows the pixels to show more color tones. With quick cyclic switching between different color tones, an illusion for a new intermediate color tone is created. For example, by using FRC, a 6-bit display panel is able to show 16.7 millioin colors, which are typical for 8-bit display panels, and not the standard 262200 colors, instead. There are different FRC algorithms.Yes

The maximum number of colors, which the display is able to reproduce, depends on the type of the panel in use and color enhancing technologies like FRC.1073741824 colors

The backlight is the source of light of the LCD display panels. The type of backlight determines the image quality and the color space of the display. There are various backlights such as CCFL, LED, WLED, RGB-LED, and etc.Edge LED

My TV was originally wall mounted but I moved and need to find a TV Stand for my 55UJ7700. Is there a LG replacement stand or do you have a recommendation something else? I believe the VESA on the 55UJ7700 is 300 x 300. Correct? Thanks

Does the 55UJ7700 have Picture-In-Picture or Picture-And-Picture? I like to watch a program while monitoring another, such as a sporting event. If that model doesn"t have that feature, are there other models that do?

The Multi-view feature on the LG 4K UHD HDR Smart LED TV - 55" Class (54.6" Diag), Model # 55UJ7700 allows you to split your screen so you can watch two braodcasts or exyternal inouts simultaneously. Multi-view may not be available for Ultra HD channels and it cannot be used at the same time with Live Playback. When you run the feature for the first time, one of the screen shows the Live TV you recently watched or an external input. The feature then memorizes the combination of settings for the two screens and provides them for future use...^IFV

On the LG 4K UHD HDR Smart LED TV - 55" Class (54.6" Diag), Model # 55UJ7700, you can configure the Digital Sound Out settings to play simultaneously through the built-in speakers in the TV and a SoundBar connected via the TV"s Optical Digital Audio Output. Regrettably, you cannot do the same when using Bluetooth Headsets. When you pair the TV with a Bluetooth Headset, you can only listen to the TV through the Bluetooth Headset...^IFV

The screws that will fit into the bolt holes in the back of the LG 4K UHD HDR Smart LED TV - 55" Class (54.6" Diag), Model # 55UJ7700 have a metric measurement which is given as M(?) x L(?) where "M" is the width of the screw and "L" is the length. The length will vary depending on the depth of the wall mount you"re using. Typically, if the wall mount you"re using is a VESA Compliant Wall Mount that supports the same A x B VESA Wall Mount Pattern for the TV, which is 300 x 300 (mm) for this TV, it should have come with the correct VESA STandard screws that would fit into the TV. The width of the screws that will fit into this TV is M6 (i.e. 6 mm). You can measure the length of the screws you currently have to determine what length you will need or you can check the instruction manual for your wall mount for that. I know that LOWE"s carries these screws in various widths and lengths so you will be able to get them from them. Most hardware stores will also carry these screws...^IFV

Although LG garnered a lot of attention at the recent CES 2017 for its new 4K Ultra HD LED LCD TVs using Nano Cell technology, lost in the marketing buzz was the fact that the majority of LG Electronics’ lower-cost 2017 4K Ultra HD LED LCD TVs now use the company’s controversial RGBW technology that arrived to much debate two years ago.

Tim Alessi, LG Electronics home entertainment marketing director, told HD Guru prior to the show that RGBW panels will be used this year in all but two series of 4K Ultra HD LED LCD TVs, encompassing 14 core-line models.

The 2017 4K Ultra HD LED LCD TV series using RGBW panels include: the UJ6300, UJ6500, UJ7700 and SJ8000. The SJ8000 is part of LG’s premium Super UHD LED LCD assortment offering its advanced new Nano Cell LED LCD technology.

The distinction is made here because the RGBW technology’s purported benefits and shortcomings have been hotly debated, primarily between LG and rival Samsung. Importantly, LG Electronics has elected over the last two years not to formally identify in literature, packaging or signage which of its LED LCD TV models use RGBW panels. However, the company generally identifies panels using In-Plane Switching (IPS) panels and other technologies.

LG uses two different forms of RGBW technology that are quite different in implementation and performance. One is used in its top-end 4K OLED TVs and the other is used for lower-tier 4K LED LCD TVs, primarily as a cost-savings measure. In the OLED approach, each pixel includes a white sub-pixel in addition to red, green, and blue, sub-pixel, to produce brighter images (used for HDR among other things). In the LCD approach, RGBW panels use a complex scheme where every fourth sub-pixel in a row is white, requiring each white sub-pixel to be shared by adjacent pixels.

Critics of the LCD approach to RGBW say the unusual sub-pixel arrangement prevents the panels from achieving full UHD color resolution, and therefore the displays do not meet the Consumer Technology Association’s (CTA) definition of a 4K Ultra HDTV – this requires 3840×2160 active pixels with 8-bit color (each pixel needing to carry a separate R, G and B subpixel across the screen). But LG has countered that its RGBW displays achieve full UHD monochromatic resolution and full resolution on the luma (brightness) channel, which is all that some other international standards organizations require for a 4K UHD designation.

Note: LG Display, which manufactures the LCD panels with RGBW technology for LG Electronics, is one of the world’s largest suppliers of LCD TV panels. It sells RGBW panels to other television manufacturers and brands. So far, none of those panel customers have called out the use of RGBW panels in their 4K Ultra HDTVs in 2016, and most have refused to disclose whether they use RGBW panels or not.

Even Samsung, which was originally the most vocal critic of RGBW technology, would not comment to us on whether or not any of the LCD panels it is reportedly starting to acquire from rival LG Display this year will be of the RGBW variety. A Samsung spokesman pointed to a long-standing company policy not to comment on issues involving component supply.

According to a Bloomberg report this week, Samsung, hampered by a global panel supply shortage, had to turn to LG Display for LCD panels this year after one of its auxiliary sources – Sakai Display (Foxconn/Sharp)–decided to stop selling Samsung LCD panels from its factories.

To its credit, LG has always fully disclosed the use of RGBW panels in its model lines when specifically asked. It has also proudly called out the technology’s various benefits including lower cost, energy savings or higher brightness (depending on the application), among others.

Critics of LG’s RGBW for LCD panels say the shared white sub-pixel scheme limits the rendering of fine text, and makes the image somewhat fuzzier when trying to read Web pages or documents delivered by a connected PC. LG denies this. Critics have also said that under some conditions, RGBW images produce lower color volume, particularly in reds, that can appear to lose saturation with higher brightness compared to pixels with full RGB sub-pixels.

The UJ7700 is really the entry model into the high end of the LED-LCD TVs offered by LG. You get most of the best features including the new Web OS3.5 system, 4K, a wide color gamut, and the magic remote.

There is no more important component of a 4K UHD TV than the video engine – particularly the ability to upscale/upconvert resolution to the native resolution of the panel. LG"s UJ7700 does a very nice job in this regard, and with much improvement over last year"s models. Processing artifacts are cleaned up nicely. The lack of 4K content is going to continue well into the future, so stellar upconverting all manner of HD resolutions 720p, 1080p, 480p is essential. The higher up the HD chain you go, the better the clarity and detail to show off the native 4K resolution. This Video engine and upscaler quality is also one of the differentiating factors moving up the price scale between models within LG. The UJ7700 uses a 4 step process to examine and enhance broadcasts, recorded video, and home video game consoles.

LG"s UJ7700 uses an IPS (in-plane-switching) panel, albeit a new one for 2017/2018. The IPS panel allows for much better picture quality from side angles without degrading color saturation and contrast much. This is one of the standout features of this TVs picture quality. There are still weaknesses in both with side angle viewing as contrast degrades, but generally the IPS panel is 20%-30% better from angles than non-IPS panel LED TVs. Reflections are also subdued by the IPS panel and front substrate.

Colors do to render more depth and slightly better saturation in these new 4K HDR models. The UJ7700 has an expanded color gamut meeting HDR standards. LG contends this is due to their new Color Prime technology-which uses phosphor (colored) based LED lighting. Out of the box colors are over saturated but after calibrating the picture settings or using the cinema (user) setting with contrast at around 80% you get natural, crisp colors. Black levels are hurt by the IPS panel. In a dark room environment, you will notice that they are not pitch black. This is a drawback of the IPS panel – a trade-off for the better side angle viewing.

The big focus TV feature for 2017/2018 is HDR (High Dynamic Range). HDR extends the range that a pixel in an LCD TV can show. This applies to the brightness and luminosity of images. Contrast is enhanced by increased brightness rather than deeper blacks. Rather than just increase the brightness of the picture overall though, the real purpose of HDR is to increase contrast in various image areas of the picture. It improves the presentation in the brighter parts of the picture and this creates more contrast with surrounding darker parts of the picture. Since picture contrast is one of the primary features in improving perceived depth, HDR is considered a major picture quality improvement even though it may not increase the overall contrast of the panel a lot. Bright colors receive enhanced purity. A good HDR image will show better shadow detail, and the scenes that you will notice the most are those with light illuminating images, such as a room that has sunlight coming in through a window and illuminating parts of the room. HDR content is and will be in short supply for a while.

The same IPS panel that causes the UJ7700 to excel from side angles performs in mediocrity in black level depth and contrast. IPS panels are especially good at side angle viewing capability, but take away from black levels. So if you are a night time, center view, movie watcher this may not be the best TV for you.

LG"s LED-LCD TVs are very easy to set up a great warm picture quality. The settings below get you very close to D65 without having to worry about a 10-point white balance adjustment. Obviously, if you are in a brightly lit room, try the Expert Bright Room Setting instead or just ramp up the backlight setting.

Sub-par color volume. The TV"s RGBW pixel structure prevents it from making bright colors anywhere near as bright as it makes white. The TV"s local dimming helps it darken dim colors, but its very low number of zones prevent it from darkening the center of our black-with-white-border slide, showing the poor black level of its IPS panel.

The UJ7700 has a 60Hz panel and can interpolate lower frame rate content by setting "TruMotion" to "User" and increasing the "De-Judder" slider. Fans of motion interpolation may be disappointed that it can"t produce as strong of a soap opera effect as 120Hz TVs such as the UH7700 from 2016.

The LG UJ7700 is great at displaying content without stutter, even low frame rate content such as 24p movies. The response time of the panel helps to smooth the transition between frames, which is good.

Back in 2016, to determine if the TV panel lottery makes a significant difference, we bought three different sizes of the Samsung J6300 with panels from different manufacturers: a 50" (version DH02), a 55" (version TH01), and a 60" (version MS01). We then tested them with the same series of tests we use in all of our reviews to see if the differences were notable.

Our Samsung 50" J6300 is a DH02 version, which means the panel is made by AU Optronics. Our 55" has an original TH01 Samsung panel. The panel in our 60" was made by Sharp, and its version is MS01.

Upon testing, we found that each panel has a different contrast ratio. The 50" AUO (DH02) has the best contrast, at 4452:1, followed by the 60" Sharp (MS01) at 4015:1. The Samsung 55" panel had the lowest contrast of the three: 3707:1.

These results aren"t really surprising. All these LCD panels are VA panels, which usually means a contrast between 3000:1 and 5000:1. The Samsung panel was quite low in that range, leaving room for other panels to beat it.

The motion blur results are really interesting. The response time of the 55" TH01 Samsung panel is around double that of the Sharp and AUO panels. This is even consistent across all 12 transitions that we measured.

For our measurements, a difference in response time of 10 ms starts to be noticeable. All three are within this range, so the difference isn"t very noticeable to the naked eye, and the Samsung panel still performs better than most other TVs released around the same time.

We also got different input lag measurements on each panel. This has less to do with software, which is the same across each panel, and more to do with the different response times of the panels (as illustrated in the motion blur section). To measure input lag, we use the Leo Bodnar tool, which flashes a white square on the screen and measures the delay between the signal sent and the light sensor detecting white. Therefore, the tool"s input lag measurement includes the 0% to 100% response time of the pixel transition. If you look at the 0% to 100% transitions that we measured, you will see that the 55" takes about 10 ms longer to transition from black to white.

All three have bad viewing angles, as expected for VA panels. If you watch TV at an angle, most likely none of these TVs will satisfy you. The picture quality degrades at about 20 degrees from the side. The 60" Sharp panel is worse than the other ones though. In the video, you can see the right side degrading sooner than the other panels.

It"s unfortunate that manufacturers sometimes vary the source of their panels and that consumers don"t have a way of knowing which one they"re buying. Overall though, at least in the units we tested, the panel lottery isn"t something to worry about. While there are differences, the differences aren"t big and an original Samsung panel isn"t necessarily better than an outsourced one. It"s also fairly safe to say that the same can be said of other brands. All panels have minute variations, but most should perform within the margin of error for each model.

In both LCD and OLED displays, producing these cells – which are highly complex – is by far the most difficult element of the production process. Indeed, the complexity of these cells, combined with the levels of investment needed to achieve expertise in their production, explains why there are less than 30 companies in the whole world that can produce them. China, for instance, has invested more than 300 billion yuan (approximately $45 billion USD) in just one of these companies – BOE – over the past 14 years.

Panox Display has been involved in the display industry for many years and has built strong and long-term partner relationships with many of the biggest OLED and LCD panel manufacturers.

Sony has many micro OLED model such as 0.23 inch, 0.39 inch, 0.5 inch, 0.64 inch, 0.68 inch, 0.71 inch. Panox Display used to test and sell many of them, compare to other micro OLED manufacuturers, Sony`s micro OLEDs are with the best image quality and highest brightness (3000 nits max).

LG Display has initially intended to halt LCD TV panel production in South Korea by the end of the 2020 while continuing production at its factory in Guangzhou, China.

LG Electronics was especially focused on procuring in-plane switching (IPS) LCD TV panels. LG Display specializes in the technology __ IPS allows for wider viewing angle and color range, as is used in premium LCD TVs.

LG Electronics initially expected that it could procure IPS panels from China’s HKC and Sakai SIO (previously Sharp). But COVID-19 delayed HKC’s ramp up of its H4, 8.6th-generation (2,250mm x 2,600mm) line in China. Sakai SIO in the meantime had difficultly procuring lasses for LCD panel production. Also, for HKC and Sakai SIO, Samsung Electronics is a more important customer than LG. These issues prompted LG Electronics to ask LG Display to extend LCD production.

LG Display produces LCD TV panels at its 7th-generation (1,950mm x 2,250mm) P7 line and 8.5th-generation (2,200mm x 2,500mm) P8 line at Paju. While both lines produce TV panels, P7 makes more of them compared to P8 which focuses on IT panels. Both lines are thought to have production capacities of 120,000 to 130,000 sheets per month.

The higher than expected demand for LCD also played a part in LG Display extending LCD production in Korea. In the third quarter, panel prices increased by 30% from the previous quarter. Price continues to go up.

Samsung Display has previously said it plans to end LCD production by 2020, it continuing to produce them. It has previously said it may extend production from Samsung Electronics’ request. Samsung Display specializes in vertical alignment (VA) LCD panels.
