    • A self light emitting display device is provided which includes a panel driver which changes a maximum voltage supplied to the self light emitting display panel according to the necessary maximum brightness, a storage unit which holds data related to a reverse gamma characteristic that is opposite to a gamma characteristic between an amount of light emitted from the self light emitting display panel and a voltage supplied from the panel driver to the self light emitting display panel, and a panel gamma generation unit which generates an output signal based on the reverse gamma characteristic by changing an applicable range of the reverse gamma characteristic according to the necessary maximum brightness while maintaining the same gradations as those when the self light emitting display panel emits light at a displayable maximum brightness. The panel driver drives the self light emitting display panel based on the output signal.
    • 提供了一种自发光显示装置,其包括:面板驱动器,其根据所需的最大亮度改变提供给自发光显示面板的最大电压;存储单元,其保存与反向伽马特性相关的数据,该反向伽马特性与 从自发光显示面板发射的光量与从面板驱动器供给到自发光显示面板的电压之间的伽马特性,以及面板伽马生成单元,其通过改变反向伽马特性来生成基于反向伽马特性的输出信号 根据必要的最大亮度,反转伽马特性的适用范围,同时保持与自发光显示面板以可显示的最大亮度发光的那些相同的等级。 面板驱动器基于输出信号驱动自发光显示面板。
