Toshiba Matsushita Display Technology Co.,Ltd.(TMD) developed low temperature p-Si TFT display allowing direct input function (touch panel function) with a finger on the screen.

Since the touch panel functions in themselves are incorporated on the glass by SOG technology, it is not necessary for attachment of the touch screen like the conventional display with touch input function as an external option, and enables thinner, smaller, and lighter.

Also, through improvement of high speed switching, light sensor, and signal processing, special and unique to low temperature p-Si, short time reading of information input and signal processing were achieved.
