| 摘要 |
The present disclosure provides a photosensitive array substrate, an optical touch screen including the photosensitive array substrate, and a display device including the optical touch screen. The photosensitive array substrate includes a plurality of gate lines for providing a gate line scanning signal, a plurality of common electrodes, a plurality of touch sensing read lines, and a plurality of photosensitive sensing units coupled to the gate lines, the common electrodes, and the touch sensing read lines for providing corresponding touch sensing control signals over the touch sensing read lines based on an intensity of external light shined on the photosensitive sensing units and controlled by the gate line scanning signal. |
