    • A video display device including an integrated atypical/typical defect compensation circuit is disclosed. The video display device includes a display panel, a memory storing atypical/typical defect information used to compensate atypical/typical defect regions of the display panel, and an integrated atypical/typical compensation circuit including a first compensator for compensating input data to be displayed on the atypical/typical defect regions, using the atypical/typical defect information from the memory, and a second compensator for finely compensating the data compensated by the first compensator, using first and second dithering patterns. The compensation circuit supplies data to be displayed on normal regions, without compensation. The video display device also includes a timing controller including a dithering unit for finely compensating data output from the integrated atypical/typical compensation circuit, using a third dithering pattern different from the first and second dithering patterns, and a panel driver for driving the display panel under a control of the timing controller.
    • 公开了一种包括集成的非典型/典型缺陷补偿电路的视频显示装置。 视频显示装置包括显示面板,存储用于补偿显示面板的非典型/典型缺陷区域的非典型/典型缺陷信息的存储器,以及集成的非典型/典型补偿电路,包括用于补偿要显示的输入数据的第一补偿器 使用来自存储器的非典型/典型缺陷信息的非典型/典型缺陷区域,以及第二补偿器,用于使用第一和第二抖动模式精细补偿由第一补偿器补偿的数据。 补偿电路提供要在正常区域显示的数据,无需补偿。 视频显示装置还包括定时控制器,该定时控制器包括抖动单元,用于使用不同于第一和第二抖动模式的第三抖动模式,精细地补偿从集成的非典型/典型补偿电路输出的数据;以及面板驱动器,用于驱动显示面板 在时序控制器的控制下。
