An LCD panel, a terminal device and a photo-sensing control method are provided. The LCD panel includes: a backlight source, an array substrate disposed on the backlight source; a photosensitive device array disposed on the array substrate; and a control circuit coupled to the photosensitive device array. By disposing the photosensitive device array on the array substrate of the LCD panel, a front panel of the terminal device is not required to be divided into multiple regions. Therefore, the camera function can be integrated into the LCD panel, and only the LCD panel is needed in the front panel of the terminal device which has both the display function and the camera function. The integration and appearance of the front panel of the terminal device is thus improved.
