OLED-TV Display/Monitor Technology News

UPDATE 23.04.2008 --> Samsung-SDI see that AMOLED comes in more medium and large-size applications – such as for monitor, notebook and TV – will adopt AMOLED panels in 2009, and in 2010, flexible display applications!

OLED-TV News at the CES-2008
Howard Stringer at the CES-2008 press conference Sonys OLED XEL-1 in USA, and Samsungs 14 and 31-inch OLED-TV:

The primary benefit of OLED displays over traditional LCDs is that OLEDs do not require a backlight to function, and consume less power during operation. OLED displays are expected to be more efficiently manufactured than LCDs and plasma displays.

The AMOLED technology have full layers of cathode, organic molecules and anode, the anode layer overlays a thin film transistor (TFT) array that forms a matrix. The TFT array itself is the circuitry that determines which pixels get turned on to form an picture.
The fledgling technology of making ultra-thin displays using organic light-emitting diodes (OLED) is starting to bear fruit finally with Sony, Samsung SDI and other makers introducing new applications.

Sony says that it is going to sell 11-inch OLED TVs for the first time in the world this year. Korean firms such as Samsung Electronics, Samsung SDI, LG Electronics, LG.Philips LCD and Neoview Kolon are also investing in the technology, which should replace the current LCD and plasma panels in the long term, becoming the norm for digital displays.

Samsung Electronics Digital Media President Park Jong-woo said that organic displays can be a breakthrough in its TV business, as the competition for creating bigger screens now does not carry much meaning to consumers.


"No matter how better and bigger TVs get, people are not going to want a 100-inch TV in their bedrooms. So I think that Internet TVs or OLED TVs will be the product for creative management,'' Park said at a meeting with the press Tuesday.

OLED panels use certain organic compounds that emit red, green and blue lights in response to electric signals. Unlike LCD and plasma screens, OLED panels do not need an additional light source, or "backlight,'' so they are slimmer and more energy-efficient, and capable of showing clearer, fast-responding images.

Cambridge Display Technology (CDT) [Nasdaq: OLED] has announced another important step in the development of polymer light emitting diode (P-OLED) display technology with the production of a number of 14 inch full color displays using ink jet printing. The displays were produced at CDT's Technology Development Centre in the UK, and feature a resolution of 1280 x 768 pixels x RGB, equivalent to almost three million sub-pixels, or over 30 million ink jet drops.

The active matrix panels use an amorphous silicon backplane, and were made using a multi-nozzle approach - up to 128 nozzles - with no interlacing, and are believed to be the first of their kind ever produced.

Seiko Epson developed the so far largest full-colored OLED display (Organic Light Emitting diode display) with the help of conventional ink printing. The prototype 40 tariff large, particularly thin and easy displays is itself by particularly high contrast, large point of view and quick response times distinguishing quantity production not 2007 ago planned.

SAMSUNG 40 Zoll PROTOTYPE OLED-TV
Samsung uses the International Meeting on Information Display 2005 conference, currently held in Seoul, to show its most recent devices. Among the products are several products that have been part of press releases but have not been shown to the public. This includes a monstrous 82-inch LCD TV panel that offers 180-degree viewing angles and a color saturation of 92 percent, according Samsung.
Full-color AMOLED displays based on a white emitter with an RGB color-filter array have been reported as an alternative technology to those displays with patterned RGB emitters due to their relatively higher cost. RGB displays based on a white emitter have a disadvantage in power consumption because part of the energy of the white light is absorbed by the color filters. Recently, a white-emitter-based AMOLED display with an RGBW pixel format has been demonstrated.

Also on display is a thin 40-inch active matrix OLED with a resolution of 1280 x 800, a brightness of 600, a contrast ratio of 5000:1 and color saturation of 80 percent. And there is news for mobile phones: Samsung demos an "always-on" section display that requires virtually no power on standby mode, according to the company: A dual-window structure divides the "indicator" display and main window. The indicator window, which only consumes 0.45mw of power, shows the time, day of week, remaining battery life, antenna status and mailbox status.

Sony OLED-TV
Sony is demonstrating two slim TVs that incorporate OLED (organic light-emitting diode) technology at CES 2007 in Las Vegas .

The 11- and 27-inch TVs are about 3mm and less than 10mm thin, respectively, according to a company press release. The 27-inch model features a full high-definition (HD) panel while the 11-inch TV is designed with a wide-SVGA panel.

The resolution of the 27-inch OLED TV is 1920x1080, the contast ratio is greater than 1,000,000:1, brightness : all white 200cd/m2, peak greater than 600cd/m2. Colors - 10 bit RGB.

11" - The resolution is 1024x600, the other technical data like the 27-inch OLED
Sony sees the chance to bring OLED Tv on the market in 2007.

01.10.2007
Sony shows their first commercial OLED TV named XEL-1.

The XEL-1 is an 11 inch display that is only 3mm thin. The measurements of the XEL-1 are 287×253×140mm.
Sony has put the ultra-thin display on a pedestal with a flexible arm. At 11 inch the Sony XEL-1 is a nice stylish desk accessory.
The latest OLED TV (XEL-1), which weighs two kilograms and is about 3mm thin, features a resolution of 940×540 and contrast ratio of 1,000,000:1, stated Sony.

The XEL-1 will be exhibited at the Sony exhibition booth at Ceatec Japan 2007 starting from October 2.

Update December 2007 Toshiba Corp said on Tuesday it had shelved plans to sell ultra-thin TVs with organic light-emitting diode (OLED) displays in 2009/10 because of the cost of mass production.
