Abstract

The embodiment of the invention provides a display panel compensation circuit structure and a display device. The display panel compensation circuit structure comprises at least two first storages, atleast two second storages, at least two third storages, at least two fourth storages, at least two fifth storages and at least two sixth storages, the second memory is used for storing the distribution information of the Demura data in at least two first memories; and the logic control panel is used for simultaneously reading the corresponding Demura data from the at least two first memories according to the distribution information so as to compensate the display panel. According to the embodiment of the invention, the method can improve the compensation speed through achieving the quick reading of the Demura data, and can improve the user experience.

Description

technical field [0001] The present application relates to the field of display technology, in particular, to a display panel compensation circuit structure and a display device. Background technique [0002] With the increasing size of display panels, many panel makers are currently developing 55-inch to 85-inch panels, and the resolution is getting higher and higher. From HD to FHD and UD, now to 8K resolution. Because, during the manufacturing process of the display panel, based on various manufacturing processes or unfavorable factors that need splicing of large-size panels, it may cause bad mura phenomenon on the panel. At present, many panel factories will do mura in the production process of the panel. compensation. The method is to take pictures with a precision camera and then generate the mura compensation table through algorithm processing, and then burn the mura compensation table into the memory on the panel. When the logic control board is powered on, it will ...
