Luminance control method and display

Abstract

A display device includes a display panel, a light emitting device that provides backlight to the display panel, and a control device that determines the brightness of the backlight that the light emitting device should provide. The control device detects a timing when the brightness of the backlight illuminating the display panel is switched; recognizes an updated brightness level that should replace, as the one to be applied, an initial brightness level representing the brightness of the backlight at the detection timing; and changes the brightness of the backlight step by step after the detection timing from the initial brightness level to the updated brightness level.
