Next Toshiba is loose indication that technical company development succeeded is no matter dim indoor bright still outdoors the handwritten input that all can undertake is based on smooth sensor feels liquid crystal face plate. The sensitivity of the optical sensor that goes up through raising liquid crystal face plate and same glass motherboard and optimize signal processing, be in dim indoor can illuminate the lamp to detect through the back the reflex that gives finger, in bright outdoors can detect the finger shadow that external light forms.

This the face plate of trial-produce is used2.8 inches(diagonally7.1cm) WQVGA (400 × 240 like element) Si of silicon of microtherm much crystallization (P-Si) TFT is passed through model liquid crystal face plate, indication color counts 5000 kinds about 60 thousand. The surroundings intensity of illumination that can have handwritten input arrives from 0 lux 100 thousand lux. Can know way according to circumstance changeover (perhaps have external light point to shadow identifying, the finger reflex that perhaps undertakes back reflecting the light identifies) , can undertake discriminating inside range of bigger intensity of illumination so. Can judge not only point to a shadow, the pen inputs usable still light.

This face plate will be exhibited in international flat monitor " Display2007 "(On April 11, 2007～ is held 13 days in Tokyo BigSight international exhibition center) on reveal.
