Toshiba Matsushita Display: an LCD display to capture images?
Toshiba Matsushita Display Technology, a monitor development and production joint-venture of Toshiba and Matsushita, informed that its engineers succeeded in making a... scanning device out of usual low-temperature polysilicon display!
The screen of new 3.5" LTPS transmissive display – Input Display – is actually an optical sensor matrix with every pixel being an active element. So, this QVGA (320x240) panel provides b/w capture at 960x240 resolution.
According to the company, this effect is possible due to high movability of LTPS display crystals that allows to reduce the size of pixel transistors and as a result provides higher photosensitivity of these devices comparing to usual TFT panels on amorphous silicon.
Of course, industry will not miss such an important breakthrough. At least, Toshiba Matsushita Display expects the serious demand for such devices. The simplest appliance is user fingerprint authentification without additional sensors.
For now we don’t have any photos of the Input Display sample, but we hope to get it along with specifications at days of EDEX 2003 to take part in Tokyo, on April 9-11.
