Abstract
A semiconductor device includes first to fourth terminals, a switch circuit, and an integrating circuit. The integrating circuit includes an amplifier circuit having a (−) terminal, a first (+) terminal, and a second (+) terminal. The integrating circuit is configured to integrate an input signal of the (−) terminal using an average voltage of a voltage of the first (+) terminal and a voltage of the second (+) terminal as a reference voltage. The switch circuit is configured to electrically connect the (−) terminal to the second terminal, the first (+) terminal to the first terminal, the second (+) terminal to the third terminal the (−) terminal to the third terminal, the first (+) terminal to the second terminal, and the second (+) terminal to the fourth terminal. The present semiconductor device is used as a semiconductor device sensing a current flowing through a pixel in a display panel.
