Abstract
The present disclosure provides a photosensitive structure, a photosensitive display substrate, and fabrication and control methods of the photosensitive display substrate. The photosensitive structure includes a first conductive layer; a second conductive layer; and a photoconductive material layer, sandwiched there-between. In response to a light illumination, the photoconductive material layer is capable of changing from an insulating state to a conductive state. One or more first constant voltage sources are configured in a periphery of the first conductive layer to charge the first conductive layer in different directions to maintain a first voltage there-on. Each current measurement unit is disposed between one first constant voltage source and the first conductive layer and configured to measure a charging current between the first constant voltage source and the first conductive layer, and configured to output current signals corresponding to the first constant voltage sources. A touch signal determination unit is connected to the current measurement units to determine a touch position.
