Aging compensation method for a liquid crystal display device, the aging compensation apparatus for a liquid crystal display device, a computer program, and a liquid crystal display device

摘要

A liquid crystal display device includes a liquid crystal display panel which is driven by liquid crystal drive output signals according to input image input signals Sin respectively corresponding to plural colors and displays a desired display image Lim, a backlight unit as a light source for transmitted light (display image Lim) from the liquid crystal display panel, a microcomputer which executes various kinds of control and processing(arithmetic operations, driving, etc.), a liquid crystal drive circuit, a backlight drive circuit, and luminance sensors (white luminance sensor, red luminance sensor, green luminance sensor and blue luminance sensor). An aging-originated change (aging change) in the display characteristics of the liquid crystal display device is automatically compensated for.
