    Abstract: A display apparatus includes an image analyzer that analyzes image data and outputs an interrupt signal at a period during which the image data of a low frequency change to the image data of a high frequency, a frequency detector that detects the high frequency, a frame rate controller that outputs a vertical synch signal of the high frequency in response to the interrupt signal, a polarity compensation controller that determines a last frame of the low frequency based on an interrupt period at which the interrupt signal is generated, generates a reversed polarity signal with respect to a polarity signal of the last frame and outputs the reversed polarity signal during a polarity compensation period close to the interrupt period, and a data driver circuit that outputs a data signal based on the reversed polarity signal to a data line during the polarity compensation period.

    Abstract: A method of compensating an image to be display on a display panel is disclosed. In one aspect, the method includes receiving a first input image and adjusting a contrast sensitivity of the first input image. The method also includes calculating a first derivative of luminance of a pixel included in the adjusted image, calculating a second derivative of the luminance of the pixel, and accumulating the first and second derivatives. The method further includes determining a burn-in causing boundary based at least in part on the accumulated first and second derivatives, receiving a second input image, and comparing the burn-in causing boundary to a boundary of the second input image to determine whether to apply burn-in compensation. The method finally includes compensating a portion of the second input image corresponding to the burn-in causing boundary based at least in part on an unsharpening filter.

    Abstract: A method of driving a display panel includes determining whether an input data signal represents a video image or a static image, determining whether the input data signal has a color difference generating pattern and outputting an output data signal. The output data signal has a first frequency if the input data signal represents a video image. The output data signal has the first frequency if the input data signal represents a static image and the input data signal includes the color difference generating pattern. The output data signal has a second frequency lower than the first frequency if the input data signal represents a static image and the input data signal does not include the color difference generating pattern.

    Abstract translation: 驱动显示面板的方法包括：确定输入数据信号是表示视频图像还是静态图像，确定输入数据信号是否具有色差产生模式并输出输出数据信号。 如果输入数据信号表示视频图像，则输出数据信号具有第一频率。 如果输入数据信号表示静态图像，并且输入数据信号包括色差产生模式，则输出数据信号具有第一频率。 如果输入数据信号表示静态图像，并且输入数据信号不包括色差产生模式，则输出数据信号具有低于第一频率的第二频率。
