More Information
Summary:A display device according to an embodiment of the present disclosure may include: a display panel; a data driver configured to be driven by dividing a driving period into an active period and a blank period, and to apply a stop voltage during the blank period; and a controller configured to change a driving frequency in frame units according to an input image, and to cause the frame to operate as a refresh frame for writing a data voltage according to the driving frequency, or to operate by dividing the frame into a refresh frame and a hold frame, in which a voltage level of the stop voltage is changed according to the driving frequency. Accordingly, it is possible to prevent stripe defects and improve uniformity of the display panel by reducing unevenness of the stop voltage, thereby improving image quality. 根据本公开内容的实施方式的显示装置可以包括：显示面板；数据驱动器，其被配置成通过将驱动时段划分为激活时段和空白时段来驱动，并且在空白时段期间施加停置电压；以及控制器，其被配置成：根据输入图像以帧为单位改变驱动频率，并且根据驱动频率使帧作为用于写入数据电压的刷新帧进行操作，或者通过将帧划分为刷新帧和保持帧来进行操作，其中，停置电压的电压水平根据驱动频率而改变。因此，可以通过降低停置电压的不均匀来防止条纹
