Abstract
A touch panel includes a plurality of pixels. Each pixel includes a light sensing component, a pressure sensing component, and a switch. The light sensing component generates a first sensing signal when sensing light. The pressure sensing component generates a second sensing signal when sensing pressure. The switch transmits the first and the second sensing signals when receiving a gate driving signal.
