OLED – Organic Light Emitting Diode
CLCD – Crystal Liquid Crystal Display
CES – Consumer Electronics Show
Sony, LG / Samsung used the Consumer Electronics Show (CES) in Las Vegas to debut prototypes of new technology TVs.
LG/Samsung jointly launched their Organic Light Emitting Diode (OLED) technology, whereas Sony introduced to the world their Crystal Liquid Crystal Display (CLCD).
Rather than being quantum-shifts in technology, such as when Plasma screens were first launched, these new technologies are developments of already established ones.
Crystal Liquid Crystal Display (CLCD)
Although Sony, along with LG and Samsung is involved with developing TVs using the OLED technology, it appears to be commercialising its own CLCD systems. By blending the benefits of existing LCD and LED technologies, Sony is able to utilise LCD picture elements (pixels) to actually generate light. Historically LCD pixels simply act as shutters, allowing light from fluorescent tubes to pass through the screen to the viewer. Sony has managed to mount microscopic Light Emitting Diodes (LEDs) in each of the LCD pixels to generate the colours and light from the panel itself rather than depend on a backlight source. Typically on a higher definition screen, each pixel is subdivided into Red, Green & Blue, hence on a 1920 x 1080 pixel screen, there are over 6 million microscopic LEDs.
The new CLCD system was demonstrated at CES in Las Vegas and was seen to have a higher contrast (up to 3.5 times) than existing commercially available TVs and a pixel response time quoted at being 10 times faster than current models.
Organic Light Emitting Diode TVs (OLED)
During CES in Las Vegas, LG & Samsung heralded the arrival of their Organic Light Emitting Diode (OLED) technology flat screen TV screens.
As the names suggests, Organic relates to the use of carbon in this new TV technology, typically previous LEDs were of course manufactured from silicon. Organic LEDs produce the colours and the light directly from within themselves, they are not dependent on an external light source such as fluorescent light tubes. The biggest benefit of the OLED technologies is that they are incredibly thin, the screen can be as thin as just 5mm (3/16”), alongside the thinness on the screen, the weights can be significantly less, a 55” TV can be weigh less than 8kg. Samsung and LG claim that this new OLED produces the very best images of any TV ever produced, offering better colour saturation and even high contrast ratios, providing images with very high levels of true white and exceptionally levels of black. When the show-model at CES was displaying an image with a black background, it was impossible to see where the image ended and the screen bezel started (screen frame).
Neither of these two new technologies have yet to be commercialised, although models are being developed, there is no information available from any manufacturer regarding the launch of consumer models. Currently however, it is thought that these new technologies will supplement existing versions, they are not seen as replacement technologies. It is most likely that any commercial models that are launched will be found at the upper end of each manufacturer’s ranges of TVs, and will definitely be significantly more expensive.
Although both CLCD and OLED technologies will offer lighter weight TVs, until the specifications of consumer models are finalised, we cannot yet offer any advice on the potential mounting bracket implications.
