Toshiba Shows Off High-Def Displays for Phones
Toshiba Mobile Display today announced new displays intended for use in devices such as mobile phones. The displays in question use low temperature poly-silicon (LTPS) technology, also known as p-Si LCD panels. These types of displays can be thinner, lighter, and require less power than some competing screen technologies. One example of a new p-Si LCD revealed by Toshiba measures 4 inches across the diagonal and crams in 720 x 1280 pixels, which makes for 367 pixels per inch. Another display offers 480 x 864 (WVGA) pixels in a screen measuring 3.3 inches at 300 pixels per inch. The displays also reach contrast ratios of 1,500:1, offer wide viewing angles, and high color capabilities. Toshiba didn't say when these displays might appear in end-user devices.
