  • Publication number: 20240029614
    Abstract: A display device and a driving method are proposed to obtain the gray value difference data of the display device when the gray value of the display device changes. So, the display device could determine the corresponding compensation data according to the gray value difference of the display device and then the compensation data and the driving data are used to drive the display device. In this way, the driving data are compensated when the display device has a variance of gray value such that the charging operation becomes sufficient to charge the display device. For example, the charging speed becomes faster to allow the display device to reach sufficient luminance such that the issues of color shifts or insufficient luminance could be avoided.
