TOUCH PANEL AND DRIVING METHOD OF TOUCH PANEL

摘要

Disclosed is a touch panel including a plurality of pixels each including a display element and a photosensor. The display element includes a transistor having an oxide semiconductor layer. The photosensor includes a photodiode, a first transistor, and a second transistor, and the first and second transistors include an oxide semiconductor layer. A driving method of the touch panel is also disclosed by which high-speed imaging is realized.
