A photosensitive unit, an array substrate of a display panel, and a manufacturing method therefore. According to the photosensitive unit, optical-to-electrical conversion is performed by using a P-type doping region, intrinsic region, and N-type doping region structure, so that a light current generated does not change dramatically easily due to the fluctuation of a working voltage, and the degree of accuracy is high. In addition, because the P-type doping region, intrinsic region and N-type doping region structure is disposed longitudinally preferably, the size of an intrinsic region can be set more flexibly, the sensing region is increased, the optical-to-electrical conversion capability is improved, a higher in ambient light sensing capability is provided, and the reliability and the sensitivity are improved. |
