Hitachi, Pixtronix demo new display at Ceatac
Tech-On are reporting that Hitachi are demoing a 2.5″ prototype MEMS screen:
The company plans to release the display from the end of 2011 to the beginning to 2012 for mobile phones, smart phones, tablet PCs, digital cameras and other mobile devices equipped with a 10-inch or smaller display.
Pixtronix's MEMS display consists of a MEMS shutter, a backlight unit using red, green and blue LEDs, driver elements (TFTs), a reflecting plate, etc. Color tones can be adjusted by opening and shutting the MEMS shutter at a high speed and changing the amounts of the light from the LED backlight unit and natural light,
Pixtronix’s display can be driven in three modes: the transparent mode, the reflectance mode and the semi-transmissive mode, which is a combination of the transparent mode and the reflectance mode.
