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.

The present invention proposes a driving circuit and a shift register. The driving circuit includes shift register circuits disposed in cascade. Each of shift register circuits includes a clock control transmittance circuit and a latch circuit. The clock control transmittance circuit is triggered by a first clock pulse. A driving pulse of a Q node at previous two stages is transmitted to the latch circuit and latched by the latch circuit. Further, the latch circuit is triggered by a second clock pulse, and then a gate driving pulse and a driving pulse of the Q node is output. So the present invention can be used in the CMOS process owing to the features of low consumption and wide noise margin.
