Abstract:
Provided are a photoelectric detection circuit and a driving method thereof, a display apparatus and a manufacturing method thereof. The photoelectric detection circuit includes: a first reset sub-circuit, a second reset sub-circuit, a first storage sub-circuit, a data read sub-circuit and a photosensitive device. A first terminal of the data read sub-circuit, a first terminal of the first storage sub-circuit, a first electrode of the photosensitive device and a first terminal of the first reset sub-circuit are connected to a first node. A second electrode of the photosensitive device is connected to a common voltage line. The data read sub-circuit is configured to transmit a voltage of the first node to a data read line in response to a signal of a scan line. The first reset sub-circuit is configured to reset the voltage of the first node.
