sxrd lcd panel made in china
Continuing to distance itself from involvement in LCD TV panel production, Samsung Display, the major global supplier of flat-panel display modules to Samsung Electronics and other global customers, revealed Monday that it has sold its majority stake in a Liquid Crystal Display (LCD) factory in Suzhou, China to CSOT.
In the deal, CSOT acquired a 60% stake in Samsung Suzhou LCD (SSL) and a 100% stake in Suzhou Display (SSM) for the equivalent of $1.08 billion, according to reports out of South Korea.
Samsung Suzhou LCD’s ownership structure is now divided between a 60% ownership position by CSOT, 30% by the Suzhou government and 10% owned by CSOT parent, TCL, according to a report on Korean business news site theelec.net.
Faced with declining profitability from LCD production as competitors, mostly from China, expanded and grew, Samsung Display previously announced its intention to exit the LCD business, while investing an announced 13 trillion won over five years in next-generation quantum dot (QD) displays.
It continues to own 7th-generation LCD factory lines in South Korea, but is in the process of changing over its Korean LCD production to new QD Display panels and small- to mid-sized organic light emitting diode (OLED) panels, the reports said.
Samsung Display will focus on production of foldable OLED panels and quantum dot nanorod displays (QNED) going forward, and expects to secure QNED production technology by 2021.
Travis, I also have the SXRD 60 inch tv with the greenish tint (started about Jan/Feb ’14) After investigating online, looks like options to replace by Sony have expired. I got one $500 estimate to repair. Might get another estimate. Most likely I’ll be replacing the TV with an 60″ LED type. It’d be more current on technology (Wi-Fi, more HDMI outputs, Smart, etc).
I just hung up with Sony on trying to get information about a green hue I have on my SXRD TV. The support tech actually lied to me 6 times before I was able to get ‘Dennis’ to admit the truth. Dennis stated that Sony has never had an ‘Optical block’ problem, that there had never been a class action suit on this issue, that they have never offered any kind of replacement, and the the internet had lied about all of this. I asked to be moved to a higher level and he stated that when he would transfer me that it would go to someone else of his level with the same information. How can you trust a company that lies to you right from the beginning?
Went TV shopping a few days ago. Sales tried to sell me a Sony. I’ll never buy another Sony! He asked why and I told him about my SXRD 60 inch.Had it since 2007. It was ok for 2 years,then went yellow.We have put up with this ever since,plus 3 proj. bulbs. Then he tells me about the consessions Sony has offered. Am I the only person on earth that didn’t know this?
Made contact with Sony and was offered three poor options..7 days to accept. Three days later I was blocked from getting any more help on my issues with the defective 2008 55″ KDS 55a3000 SXRD. What to do? Sony never even told me of this product built to fail.
I just worked with Sony on my 55″ SXRD tv issue that included a yellow tint to the picture. The offer I got was for a 55KDL500 for $300 or a 46″ model for $25. I took the $300 55″. Shame though that the picture on the new LCD is not as clear as the SXRD when working well.
The optical block failed about 2 months ago on my 4 year old 60″ SXRD (KDS60A2000 – manufactured Sept. 2006 ). I just got off the phone with Sony…the offers are:
Have a KDS-R60XBR1 with optical block problem. Called Sony about two weeks ago. They provided an event # and asked that I provide a pic of the TV with the event number and the seriel number tag from the back of the tv. You must carefully remove it and tape it on the paper. I took a pic of the tv during a Ford commercial which has lots of white screen space which clearly shows the green halo. I’m now waiting for the 60EX700 LCD HDTV to be shipped ($325+tx). Thanks everyone for your posts.
I have a 60″ SXRD XBR2 that has been “Fixed” 2 times , how did you hear about this deal ? How can i get this deal ? I know the extended warranty runs out in a month of whatever .. i paid $4300 for poop basicly
**The 2005 3LCD models are unique in that they are the only models between 2003 and 2007 that have not had a Sony warranty extension.***The expiration date of the extended warranty was originally 10/31/2008, but, based in part on the settlement of a class action lawsuit, on 11/12/2007, Sony extended the expiration date to 6/30/2009.
****The expiration date of these extended warranties was originally 6/30/2010, but, in mid-June 2010, Sony extended them to match those in the pending Cardenas SXRD2 class action lawsuit settlement.
liquid crystal on silicon (LCoS) technology ("SXRDTM" models).All of the 2002-2006 and some of the 2007 modelsuse the WEGATM video processing engine and are generally known as Grand WEGAs. The remaining 2007 models use the newer BRAVIATM engine and branding.
SXRD models (green, yellow, purple, pink, or magenta blob, stain, haze, halo, or tint, and other discolorations)Image of a yellow stain (lower-right of image) by Mightyp on AVS Forum:
The optical blocks in SXRD models appear to have defects that cause predominantly green blobs, green haze, and/or yellow stains, although other discolorations (e.g., magenta-colored tint) also occur.An Opinion and Order from a class-action lawsuit on the 2005 models provides unique insight into the causes of the discolorations. A majority of the green issues that appeared in the 2005 SXRDs (the green blobs) arose almost immediately after they were put into service, often occurring near the middle of the screen, sometimes being donut-shaped. Sony claims that they identified and fixed that issue ("temperature fluctuations at the calibration stage of the assembly line") within a month of the start of production. Sony claims that this only affected the first ~7,000 TVs to be produced.Sony also claims that other minor causes of green issues (the green haze) were identified and fixed by 1/2006, although no details were provided.
Most likely, all of the green discolorations occurred due to the presence of improperly polarized light in the green channel, arising from defective green polarizers and/or SXRD panels. There is more recent evidence from a subsequent SXRD class action lawsuit that green haze can be caused by skin oil or debris introduced during the manufacturing process (presumably, optical block assemblers touching the parts with their bare fingers). However, Sony claims that they cleaned such optical block parts in a clean room prior to releasing them.
Sony further claims that the yellow stains in the 2005 SXRDs, which tend to start in the upper or lower right corner, were caused by a "microscopic material" in the liquid crystal panels, disrupting their uniformity over time during prolonged exposure to UV light produced by the projection lamp. Sony claims that the extent of the discoloration depended on the amount of microscopic material present in the panel, which varied from TV to TV, and the frequency of usage by the consumer. They also claim that service records indicate that the issue always appeared within the first 3,000 hours of usage, if it was going to happen.
Sony convinced the Plaintiffs counsel and judge in the class-action lawsuit that virtually all of the defective TVs that were subject to the problems would have exhibited them by the optical block warranty extension expiration date (6/30/2009), given the claimed 0-3,000 hour time period to appearance. However, inconsistent with Sony"s claims, many 2005 SXRD owners have experienced the same failures on the allegedly re-engineered optical blocks. In addition, original optical blocks have continued to fail after the extended warranty date and the claimed 3,000 hours of usage. Furthermore, similar issues are now being reported by owners of both the 2006 and 2007 model year SXRDs, which were largely produced after the alleged 10/2006 fix on the 2005 models.
A variety of other discolorations also affect SXRD models, including magenta or purple or other colors "tinting" various parts of the image. Some discoloration may be evident when the TV is first turned on, but then it may change or disappear after a period of time. SXRD technology is highly reliant on precise light polarization, so smaller degrees of degradation of the parts in the optical block and/or temperature changes can affect the image in these ways.
The blue discolorations seem to be the most common, particularly in the earlier (2003-2005) 3LCD models, although they are also observed in the more recent 3LCD models, as well as the SXRD models. These discolorations can take the form of blue blobs, haze, lines, bands, dots, star pattern, etc. In some cases, the discoloration is centered around an oval-shaped anomaly in the middle of the screen. In many cases, the discoloration (e.g., haze) is most visible on a gray background, but in other cases, the discoloration is visible on a black background (e.g., blobs). Once they become evident, the discolorations tend to accumulate and spread across the entire screen over the course of a few weeks to months.
The precise cause(s) of these discolorations have not been revealed by Sony, but the problem is well-known in the industry.Thediscolorations tend to be bluish in color,because the parts in the blue light path (particularly the blue polarizing filters and liquid crystalpanels) aresubject to the highest energy light (including UV) and heat. Photochemical and heat-based degradation of the blue polarizing filters can allow stray, improperly polarized blue light to pass through the blue LCD panel and onto the screen, leading to blue blobs on images that should be black. Photochemical and heat-based degradation of compounds in the blue LCD panel (e.g., the liquid crystal itself and/or alignment layers) can cause irregular distribution and/or alignment of the of the liquid crystal. This can lead to improper polarization of blue light as it passes through the damaged areas of the panel, resulting in the projection of stray blue light onto the screen.
images--typically called burn-in on older CRT and plasma displays. For example, this can occur in areas of black bars (e.g., letterboxes), in news ticker areas, or when pausing a program on a DVR.As the liquid crystal panels degrade over time, the
While the 2003-2004 3LCD models tend to have primarily blue discolorations, as described above, they can also suffer from stains in the yellow range, and this seems even more common in the newer 3LCD models (e.g., 2005-2006), particularly the A10s. These discolorations tend to start on the edges or appear within oval-shaped anomalies, and to spread over time. Similar to the yellow stains in the SXRDTM models, the yellow color arises due to light being completely blocked in the blue light pathdue to photochemical and heat-based damage (e.g., darkened areas on the orange-colored polarizing filter in the blue light path). The improper blockage of blue lightleaves the predominantly yellow light from the combined green and red light paths. TriState Module sells the orange-colored polarizing filter for the blue light path and reports that it can fix yellow discolorations.
On top of the high risk for blue discolorations described above, some2003-2004 3LCD modelsare also susceptible to developing an opaque, non-moving pattern on the screen, which is particularly evident on white or light backgrounds. This is referred to variously as stationary scribble, squiggly, random line, or road-mapping, and tends to be a solid color such as yellow, purple, or blue-green on a white background, but it varies somewhat depending on the specific color of the image on the screen.The problem tends to grow worse over time.
For the most part, this problem seems to have been caused by defective materials in a specific lot of LCD panels that were installed in the optical blocks, whichare particularly sensitive to damage arising from hot-cold (on-off) cycling. The color of the scribbles likely correlates with the light path with the damaged LCD panel. For example, damage to the blue panel may selectively block blue light in the damaged areas, leading to a yellow scribble (green plus red), damage to the green panel may lead to a purple scribble (blue plus red), or damage to the red panel may lead to a blue-green scribble. In some cases, different colored scribbles appear in different areas on the same TV, suggesting damage to multiple panels.
There is some evidence that leaving the TV on for an extended period (e.g., several days) can, at least temporarily, resolve or reduce this issue, perhaps by causing the defective panel to heat up, but this is not a complete or permanent fix.
For reference,in addition to liquid crystal projection technology (3LCD andLCoS/SXRDTM), othernewer technologies at the time included digital light processing (DLP) projection,plasma flat-panel,and LCD flat-panel. In the large screen market, DLP and plasma were in direct competition with liquid crystal projection in its heyday, and LCD flat-panels have overtaken the market as prices have come down on larger panels.
An industry group of LCD projection manufacturers called the "3LCD Group" was formed in 2004 to help market the 3LCD microdisplay technology. Sony is a member of this marketing group, and, along with Epson, accounted for most of the production of the LCD microdisplay panels used in the projection models. Although the current 3LCD Group web site refers only to front projectors, it included rear-projection TVs when they were in production. For example, see this version of the 3LCD Group web site archived in January of 2005. Here is an excerpt from a 1/7/2005 3LCD Group press release:
“As the U.S. market leader in microdisplay televisions, Sony has always been committed to providing consumers with video products that exceed their expectations,” said Mike Fidler, senior vice president in Sony Electronics’ Home Products Division. “3LCD technology fulfills this role by offering an ideal balance between superior performance, overall reliability and manufacturing efficiency.”
Liquid crystal projection TV sales and marketing efforts attempted to steer customers away from competing plasma TVs by citing a short 10,000-20,000-hour lifespanof the plasma tubes (less than 10 years at 3-6 hours per day).In addition, the longevity of competing DLP projection TVs was questioned based on the use of moving parts (DLP technology uses a spinning color wheel with millions of hinged micromirrors). Consistent with this, Sony and its 3LCD Group have released marketing statements such as the following:
It is generally accepted that liquid crystal flat-panel displays have an expected life span of about 60,000 hours(about 27 years at 6 hours per day)(e.g., site 1, site 2, site 3). The liquid crystal microdisplay panels in Sony"s 3LCD and SXRDTM TVs are a bit different than flat-panels. However, Sony and the 3LCD Group do not differentiate LCD flat panels and microdisplays when speaking about reliability. For example, the following statement can be found on the 3LCD Group web site:
Reliable, Road-Tested Tecnology: LCD technology surrounds us – HDTVs, PDAs, mobile phones, monitors and more...this powerful and road-tested technology is an optimal way to achieve sharp, beautiful images. 3LCD systems are reliable and use a simple optical design: 3 chips and 1 prism.
Furthermore, the estimated 60,000-hour lifespan of an LCD flat panel is actually based more on the longevity of the fluorescent back-lighting than the liquid crystal components themselves. So, if the lighting systems were replaceable on these units, the lifespan could, theoretically, be much longer.In liquid crystal projection systems, the lamps are, in fact, user-replaceable, and Sony has exploited this to further promote the longevity of the technology. They strongly promoted that their TVs only needed a lamp change every several years to restore the TV to a like-new condition. Here are some quotes from some of Sony"s marketing:
The Fountain of Youth - User-Replaceable UHP Lamp. In the past, the gradual loss of picture quality was just part of owning a TV. Once the picture got to a point where it was unwatchable, the TV was replaced and the process started over. Sony recognizes the investment in time and money that a TV represents. That is the reason that Grand WEGA comes with an ingenious user-replaceable UHP lamp. After countless hours of enjoyment, simply replace the lamp and your Grand WEGA is as good as the day you bought it. In fact, with Sony"s renowned quality, Grand WEGA may be the last TV you ever own.The implication from these quotes is that liquid crystal rear-projection TVs could have an even longer life than a liquid crystal flat-panel display, and even CRT-based TVs, due to the user-replaceable lamps. In fact, a "white paper" from Sony on their projection systems directly suggests that liquid crystal microdisplay (fixed-pixel) projection panels offer "far longer life" than CRT-based TVs (e.g., see page 23):
CRTs have phosphors that are subject to burn-in when an image stays on the screen too long...Fixed-pixel projector display panels are immune to burn-in, offering far longer life. And the SXRD panel is particularly robust.However, unlike flat-panel liquid crystal displays with non-damaging fluorescent back-lighting, the UHP lamps in Sony"s rear-projection TVs create substantial direct heat, direct light (e.g., ultraviolet), and indirect heat (produced by conversion of reflected light). This damaging energy is focused on the small filters and liquid crystal panels within the optical block, significantly reducing lifespan.
Chinese display panel makers accounted for nearly half of the share in the global liquid crystal display TV panel market in the first half of this year, dominating the industry.
Beijing-based market researcher Sigmaintell Consulting said shipments of LCD TV panels worldwide totaled 140 million pieces in the year"s first half, up 3.6 percent compared with the same period a year ago.
The supply of TV panels though has surpassed demand due to the slowdown in the global economy and weaker consumer purchasing power. Manufacturers are facing severe challenges from falling panel prices, the Sigmaintell report said.
The shipment of BOE"s LCD TV panels stood at 27.6 million in the Jan-June period while LG Display followed with 22.7 million, down 4.5 percent year-on-year. Innolux Display Group was in third place, having shipped 21.9 million units.
Shenzhen China Star Optoelectronics Technology Co Ltd, a subsidiary of consumer electronics giant TCL Corp, ranked fourth, shipping 19.3 million pieces of TV panels. Chinese panel makers accounted for a 45.8 percent share in the global LCD TV panel market.
Sigmaintell estimated that the gap between supply and demand would widen further, and the panel market may face a long-term risk of oversupply. The industry may have to undergo a reshuffle given fierce market competition, it said.
The panel makers must reduce costs, optimize their internal structures, promote technological innovation and explore more innovative applications, the report by the consultancy said.
Separately, BOE"s Gen 10.5 TFTLCD production line has entered operation in Hefei, Anhui province. The plant will produce high-definition LCD screens of 65 inches and above.
CSOT also announced in November last year that its Gen 11 TFT-LCD and active-matrix OLED production line had officially began operation. The project will produce 43-inch, 65-inch and 75-inch liquid crystal display screens.
China is expected to replace South Korea as the world"s largest flat-panel display producer in 2019, a report from the China Video Industry Association and the China Optics and Optoelectronics Manufacturers Association said.
"The average size of TV panels is likely to increase 1.4 inches in 2019. The 65-inch dimension will become the most popular size of TV," Li Yaqin, general manager of Sigmaintell, said while adding the 65-inch TV will become the mainstream screen in people"s living rooms in the future.
Compared with traditional LCD display panels, OLED has a fast response rate, wide viewing angles, high-contrast images and richer colors. It is thinner and can be made flexible.
