14 DAY TRIAL // Samsung Electronics announced yesterday the developing of the first 40 inch single-sheet OLED designed for TV sets. The prototype, which is compatible with the high-definition technology, offers a resolution of 1280 x 800 pixels (WXGA) and is based on an a-Si (amorphous silicon) active matrix that allows a quick response with minimum power requirements.
The first display build around this technology was announced by Samsung in January, but the size of that model was only 21 inches.
The OLED technology is considered the substitute of LCDs and PDPs (plasma display panel), but until recently, technological limitations prevented the correct implementation of organic LEDs into high definition displays.
Considering that this 40 inch model has been developed using an a-Si structure, similar to the one used in LCDs, it's possible that OLEDs will be assembled in the same locations and with the same production lines, only minor changes being necessary.
The improvements are not related only to the dimension of the display, its luminosity increasing from 400 to 600 cd/m2, while ensuring a contrast of 5,000:1. The ultra-thin design of this prototype and of the one from January enables the Korean producer to say that this solution, capable of ensuring thicknesses of only 3 cm, will replace current LCD TV sets.
The 40 inch OLED will be exhibited during the conference Society for Information Display, organized in Boston between May 24 and 27.
