Patent ID: 11776299

Abstract:
A photoelectric sensor and a method for driving the same, and a display apparatus are provided. The photoelectric sensor includes a photosensitive circuit including a photoelectric diode, a reset transistor, a voltage conversion transistor, a read control transistor, and a read transistor that is a p-type transistor. The reset transistor, a first electrode of the photoelectric diode, and a control electrode of the voltage conversion transistor are electrically connected to a first node. The voltage conversion transistor, read control transistor, and a control electrode of read transistor are all electrically connected to a second node. The reset transistor is turned on by its control electrode to reset the first node. The voltage conversion transistor and read control transistor are turned on by their control electrodes, respectively, to control a voltage of the second node. The read transistor outputs a detection signal under control of its control electrode.
