Abstract: PURPOSE: A display having a function of controlling the brightness of a back light and a method of controlling the display are provided to control the back light in response to the luminance of an input video signal to improve picture quality of the display. CONSTITUTION: A display includes a video signal processor(110) for processing an input video signal, a color signal extractor(120) that extracts color signals from the input video signal processed by the video signal processor, and a display panel(140) that drives a display screen according to the color signals and has a back light(147) for irradiating lights on the display screen. The display further includes a color signal average value calculator(160) that receives the color signals and calculates an average brightness of the input video signal, an inverter(150) that switches currents to the back light, an inverter current limiter(170) for limiting current supplied to the inverter, and a controller(180) that controls the inverter current limiter to control the quantity of current supplied to the back light through the inverter according to the average brightness of the input video signal.
