Abstract: A display device includes: a display panel including a first display area and a second display area; and a panel driving block which provides, to the first display area, a first data signal generated by converting a first image signal, which corresponds to the first display area, based on a first reference color coordinates in a color space, and provides, to the second display area, a second data signal generated by converting a second image signal, which corresponds to the second display area, based on second reference color coordinates in the color space. The second reference color coordinates are color coordinates obtained by shifting the first reference color coordinates in the color space.

Abstract: A display device may include a data driver, a data line, a display panel that includes a first sub-pixel and a second sub-pixel both connected to the data line and respectively positioned in a first region and a second region of the display panel, and a timing controller that may receive first-type image signals and second-type image signals. The first-type image signals may correspond to a first gray-scale and may correspond to the first region. The second-type image signals may correspond to a second gray-scale and may correspond to the second region. The timing controller may use the first gray-scale to generate a compensated gray-scale if a difference between the first gray-scale and the second gray-scale is greater than a reference value. The data driver may generate a gray-scale voltage according to the compensated gray-scale and may provide the gray-scale voltage through the data line to the first sub-pixel.

Abstract translation: 显示装置可以包括数据驱动器，数据线，显示面板，其包括连接到数据线并分别位于显示面板的第一区域和第二区域中的第一子像素和第二子像素 以及可以接收第一类型图像信号和第二类型图像信号的定时控制器。 第一类型图像信号可以对应于第一灰度级并且可以对应于第一区域。 第二类型图像信号可以对应于第二灰度级并且可以对应于第二区域。 如果第一灰度级和第二灰度级之间的差大于参考值，则定时控制器可以使用第一灰度级来生成补偿的灰度级。 数据驱动器可以根据补偿的灰度级产生灰度级电压，并且可以通过数据线将灰度电压提供给第一子像素。
