Samsung demos e-paper
Samsung this week will display its new e-paper concept prototypes along with its display products at the 45th annual Society for Display (SID) 2007 exhibition in Long Beach, California (May 22-24). The company is exhibiting its 40-inch LCD TV with LED backlight, which offers a contrast ratio of 10,000:1--almost five times higher than that of LCD panels with a CCFL backlight, the company claims. In addition, it says that color saturation is also 105 percent of the NTSC standard.
The company is also exhibiting the world's largest (A4-sized, 14.3-inch diagonal) color "electronic paper", a plastic, flexible display that it claims can deliver undistorted color images even when the surface is bent. The e-paper device also continues to show a static image after power has been shut off. For the "concept" model, the company used 130-degree celsius low-temperature amorphous (non-crystalline) silicon processing to prevent distortion of the plastic substrate.
In addition, it is also exhibiting a 40-inch black-and-white e-paper concept device, which it says is the world's largest EPD (electrophoretic display); it can be used for creating extra-large digital information displays (DIDs) that features HD resolution (1,366 X 768 pixels) and ultra-low power consumption: 300mW at one frame per minute--about 1/500 that of a conventional LCD display.
Other products being exhibited at this year's SID include a 24-inch LCD monitor panel with LED backlight, with room for two A4 pages side-to-side and two more inches for the Windows Vista sidebar panel. The company is also exhibiting a double-sided 2.22-inch LCD panel for mobile phones.
