Abstract: A display device includes a display panel, a mold frame, and graphite sheets. The mold frame includes a mold slot portion therethrough to support the display panel. The graphite sheets include a central portion on a rear surface of the display panel, and end portions passing through the mold slot portion to be on the rear surface of the mold frame. The graphite sheet is rolled and arranged in a mounting space between the display panel and a back cover, such that heat generated from the display panel may be dissipated to the outside via the graphite sheet and the back cover.

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。
