In order to eliminate the Mura defect of the display panel, the display panel is usually further processed by a DeMura (brightness non-uniformity compensation) process at present. DeMura is a process for compensating Mura, and mainly comprises the following steps: the method comprises the steps of shooting a picture of a display panel by using a camera to obtain Mura information in the display panel, then extracting and correcting Mura through a corresponding algorithm to obtain a compensation table (DeMuraTable) for hardware (such as a processor) to interpolate and call, and finally compensating abnormal pixels according to the compensation table, so that the Mura defect is eliminated, and the display panel reaches a display standard.
However, in the actual production process, the DeMura device inevitably generates vibrations during operation and manual operation, and these vibrations affect the shooting definition and accuracy of the display panel, further affect the accuracy of the Mura test result, and finally affect the effect of the DeMura, so how to eliminate the influence of the vibrations on the Mura test result is always a technical problem in the field.
