PHOTOSENSITIVE UNIT, ARRAY SUBSTRATE OF DISPLAY PANEL AND MANUFACTURING METHOD THEREOF

摘要

The present disclosure relates to a photosensitive unit, an array substrate of a display panel and a manufacturing method thereof. In the photosensitive unit, a PIN structure is adopted for photoelectric conversion, and the generated photocurrent has low probability of dramatic change due to the fluctuation of a working voltage, and thus the accuracy is relatively high. In addition, because the photosensitive unit preferably has the PIN structure arranged longitudinally, when the photosensitive unit is configured on the array substrate of the display panel, the sizes of the length, width and height of the intrinsic region can be designed in a more flexible manner. Therefore, the photosensitive region of the photosensitive unit can be enlarged to a maximum extent, and the photoelectric conversion efficiency can be improved. Consequently, the array substrate of the display panel including the photosensitive unit and the display panel have better ambient light sensing capability, high sensitivity and high reliability. The present disclosure is applicable to various display panels.
