Abstract

The embodiment of the invention provides a display device and a mura processing method, relates to the technical field of display, and can dynamically adjust the demura data of the display device to eliminate dynamically changing mura so as to provide better uniformity use experience for users. The method comprises the following steps: receiving a brightness correction instruction; the brightness correction instruction is used for indicating to optimize the brightness of the display; in response to the brightness correction instruction, determining the demura data of the mura area in the display according to the first accumulated display time; the first accumulated display time is used for indicating the accumulated starting time of the display, and the demura data is related to the first accumulated display time; and adjusting the brightness of the mura area according to the demura data. The method is used for brightness correction of the display equipment.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a display device and a mura processing method. Background technique [0002] The brightness uniformity of a liquid crystal display device is an important indicator to measure its display effect. The light spot caused by the uneven brightness of the screen during the use of the liquid crystal display device will lead to a decrease in the user experience. The light spots that appear due to uneven brightness of the liquid crystal display device during use are called mura. [0003] In view of the mura problem of liquid crystal display devices, demura data is usually stored in the internal memory chip of the liquid crystal display device when it leaves the factory to eliminate the mura problem. When the liquid crystal display device is turned on, the mura can be corrected by calling the demura data to compensate for Eliminate mura. However, since these demura data are ...
