LIQUID CRYSTAL DISPLAY DEVICE, LIGHT SOURCE DEVICE, AND LIGHT SOURCE CONTROL METHOD

摘要

A liquid crystal display device includes a liquid crystal display panel which periodically performs graduation display and non-graduation display, a backlight which illuminates the liquid crystal display panel, and a light source control circuit which sets an illumination period that allows illumination of the backlight for the gradation display and drives the backlight unit during the illumination period. The light source control circuit is configured to drive the backlight intermittently during the illumination period in limiting the luminance of the backlight.
