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.
