    Abstract: A display device includes a display panel, a dimming controller, and a panel driver. The display panel includes a plurality of pixels. The dimming controller generates at least one temporary voltage set by performing a first interpolating operation using a (j)th band voltage set and a (j+1)th band voltage set among first through (i)th band voltage sets corresponding to first through (i)th dimming bands, respectively, and generates a grayscale gamma voltage set corresponding to target luminance by performing a second interpolating operation using the temporary voltage set and the (j)th band voltage set. The panel driver drives the display panel by converting image data into a data signal based on the grayscale gamma voltage set and by providing the data signal to the pixels.

    Abstract: Methods of correcting gamma and a display device employing the same are disclosed. In one aspect, the method includes periodically measuring, at a plurality of predetermined times, a single color measurement luminance related to a single color component that is displayed on the display panel. The method further includes calculating a luminance difference between the single color measurement luminance and a single color target luminance. The single color target luminance is a target luminance of the single color component at each of the predetermined times. The method also includes changing a gamma setting for a plurality of data signals provided to the display panel based on the luminance difference.

    Abstract translation: 公开了修正伽马的方法和采用该方法的显示装置。 在一个方面，该方法包括在多个预定时间周期性地测量与在显示面板上显示的单一颜色分量相关的单一颜色测量亮度。 该方法还包括计算单色测量亮度和单色目标亮度之间的亮度差。 单色目标亮度是每个预定时间的单色分量的目标亮度。 该方法还包括基于亮度差来改变提供给显示面板的多个数据信号的伽马设置。
