LUMINANCE CONTROL DEVICE AND DISPLAY DEVICE COMPRISING THE SAME

A display device is disclosed in which a luminance control device includes a temperature sensor that detects a temperature of a display device; an average picture level part that calculates an average picture level, which defines an average brightness of an image input into the display device; and a...

description A display device is disclosed in which a luminance control device includes a temperature sensor that detects a temperature of a display device; an average picture level part that calculates an average picture level, which defines an average brightness of an image input into the display device; and a luminance control part that generates a temperature-dependent peak luminance, which varies with temperature and average picture level, based on a top gain curve defining how a maximum luminance decreases as the temperature of the display device rises and a bottom gain curve defining how a minimum luminance decreases as the temperature of the display device rises, wherein the luminance control part fixes the temperature-dependent peak luminance at a specific luminance level, regardless of changes in average picture level, at a specific temperature in a high-temperature range which is higher than a room-temperature range.
