Abstract: 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.

Abstract: An input signal from a Dsub connector and BNC connectors is selected by an analog switch. The frequency of horizontal and vertical synchronizing signals applied from one connector end is measured by a synchronizing frequency detection circuit. The frequencies of horizontal and vertical synchronizing signals applied from the other connector end are converted into voltage values by F/V converters. A microcomputer determines the presence of a synchronizing signal and selects an input signal from the connector end of a high priority level set in a non-volatile memory.
