TOUCH PANEL AND DRIVING METHOD THEREOF

摘要

An object is to provide a touch panel with high-accuracy and high-speed operation. A touch panel includes a plurality of pixels each including a display element and a photo sensor, a photo sensor reading circuit to which an output signal of the photo sensor is provided, a display element select circuit which provides an image signal to the display element, a plurality of edge sensitive latches provided in series, and a logic circuit. The logic circuit generates a signal by performing a logic operation on an output signal of the plurality of edge sensitive latches and provides the generated signal to the photo sensor reading circuit.
