Brightness control device for controlling display screen brightness of liquid crystal display device, program for brightness control device, and liquid crystal display device

摘要

PROBLEM TO BE SOLVED: To provide a technology to control luminance of a display screen of a liquid crystal display device that takes a light source determining the luminance of the display screen as a heat source and is adapted to heat source characteristics of the light source.SOLUTION: A luminance control device controlling luminance of a display screen of a liquid crystal display device acquires information on the temperature of the inside or the surroundings of the liquid crystal display device (step S110), and controls the luminance of the display screen on the basis of the acquired information on the temperature (step S120).SELECTED DRAWING: Figure 2
