CES: Sony shows 55in, full HD “Crystal LED” self-emitting display
Sony has developed a self-emitting display technology, dubbed Crystal LED Display, which it demosntrated in a full HD, 55-inch prototype model at the International Consumer Electronics Show (CES) in Las Vegas, writes Richard Wilson.
It is claimed to be the first 55-inch full HD self-emitting display using LEDs as the light source.
The self-emitting display uses ultrafine LEDs in each of the red-green-blue (RGB) colours, equivalent to the number of pixels (approximately six-million LEDs for Full HD).
The RGB LED light source is mounted directly on the front of the display, which the company claimed improved the light use efficiency.
“This results in images with strikingly higher contrast (in both light and dark environments), wider color gamut, superb video image response time, and wider viewing angles when compared to existing LCD and plasma displays, with low power consumption,” said Sony.
According to Sony, when compared to its existing LCD displays, the 55-inch prototype exhibited at CES is has approximately 3.5 times higher contrast in light environment, approximately 1.4 times wider color gamut, and approximately 10 times faster video image response time.
Power consumption is approximately 70W.
Sony said it will continue its development and commercialisation of organic light emitting diode (OLED) displays.
