ABSTRACT:
A display includes a liquid crystal display panel, a back light, an inverter that supplies electric power to the back light and adjust an intensity of illumination of the back light, a selector that selects a function to adjusts the intensity of illumination of the back light, a brightness distribution data detector that detects the brightness distribution data of the inputted video signal, a sensor that senses the environmental intensity of illumination, and a controller that determines the lightness of an image based on at least one of the environmental intensity of illumination sensed by the sensor for an environmental intensity of illumination and the brightness distribution data detected by the brightness distribution data detector according to the selector, and that controls the inverter to adjust the intensity of illumination of the back light according to the determined lightness.
