Sanyo Epson today said that it has developed a 2.2" cellphone display that is just 1.1 mm thick and can display QVGA (320 x 240 pixel) resolution. The new device is based on amorphous silicon (a-Si) technology and reaches a brightness of 350 candelas per square meter.

The company confirmed that it will be mass-producing the display but declined to specify when the device will be available. Samsung also recently revealed higher-resolution mobile displays, including a 3" device that supports full VGA (640x480 pixel).
