Abstract: A method of driving a display panel includes dividing an input image into a plurality of segments; generating flicker levels of respective ones of the segments; determining a frame rate of the display panel based on the flicker levels of the segments; and outputting a data voltage to the display panel at the frame rate.

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。

Abstract: A display device includes: a display unit including a plurality of pixels and a plurality of division areas; a data driver configured to apply a data signal corresponding to image data to the display unit, and to control a slew rate of the data signal, based on a bias voltage; and a bias controller configured to control the data driver so that the slew rate of the data signal is changed for each division area, based on a luminance variation of the image data corresponding to each of the division areas.
