Abstract:
A method for controlling a backlight luminance in which a reference voltage is set, a sampling voltage is generated based on the reference voltage, and a net photo current signal is generated by a photo current sensing element and a dark current sensing element. The net photo current signal is generated independently of temperature variations. A luminance control signal is generated based on the sampling voltage. The luminance of the backlight assembly is controlled using the luminance control signal. Therefore, variation of the luminance of the backlight assembly may be minimized, although external luminance, temperature, and variation between different photo sensors, the deterioration of the elements, and the like, may be changed.

A shift register includes a plurality of stages each generating an output signal in sequence and including a buffering section, a driving section, a first charging section, and a charging control section. The buffering section receives one of a scan start signal and an output signal of a previous stage so that the driving section generates the output signal of a present stage. The first charging section includes a first terminal electrically connected to the driving section and a second terminal electrically connected to a first source voltage. The charging control section applies the output signal of a next stage to the first charging section. Therefore, a gradual failure of TFT is reduced.

The light sensing device includes a control electrode that is electrically connected to the scan line to receive the scan signal, a first current electrode that is electrically connected to the power source line to receive the bias voltage, and a second current electrode that is electrically connected to the readout line to apply a light sensing signal to the readout line when the light sensing signal senses an external light.
