55.2: Integrated Active Matrix Capacitive Sensors for Touch Panel LTPS-TFT LCDs

We have developed active matrix capacitive sensors for detecting touch events in low-temperature polycrystalline silicon (LTPS) TFT LCDs with Fringe-Field Switching (FFS) technology. These sensors enable touch events to be detected regardless of ambient light and enable touch events to be input simultaneously at 3 or more points.
