Abstract:
A compensation method of mura phenomenon of a curved liquid crystal panel is provided, including first, obtaining image mura compensation data of the curved liquid crystal panel according to a collected image of a camera, the image mura compensation data including: a mura compensation value and a compensation point location corresponded with the mura compensation value, the compensation point location being a location of a compensation point in the collected image of the camera; then implementing correction to the compensation point location in the obtained image mura compensation data to acquire a compensation point location after correction, which is employed to replace the compensation point location in the image mura compensation data to obtain plane mura compensation data of the curved liquid crystal panel; and finally, implementing mura compensation to the curved liquid crystal panel according to the plane mura compensation data.

Claim (Index 8):
A compensation method of mura phenomenon of a curved liquid crystal panel, comprising the following steps:\n Step  1 , providing a curved liquid crystal panel and a camera; shooting the curved liquid crystal panel that shows a screen image with the camera to collect a plane image of the curved liquid crystal panel, and obtaining image mura compensation data of the curved liquid crystal panel according to the collected plane image, wherein the image mura compensation data comprises: a mura compensation value and a compensation point location corresponding to the mura compensation value, and the compensation point location is a location of a compensation point in the collected plane image of the camera; Step  2 , implementing correction to the compensation point location in the image mura compensation data obtained in Step  1  to acquire an after-correction compensation point location, such that a corrected position of the compensation point on a plane development diagram of the curved liquid crystal panel is determined according to the after-correction compensation point location and the image mura compensation data is corrected to obtain plane mura compensation data by changing the compensation point location in the collected plane image to the corrected position on the plane development diagram; and Step  3 , implementing mura compensation to the curved liquid crystal panel according to the plane mura compensation data obtained in Step  2 , wherein the compensation point on the curved liquid crystal panel that defines the compensation point location on in the plane image collected by the camera is corrected to the corrected position on the plane development diagram of the curved liquid crystal panel; wherein the camera is set at a fixed position for shooting the curved liquid crystal panel; and wherein the camera shoots the curved liquid crystal panel three times, and gray scales of images as shooting the curved liquid crystal panel for the three times are different, so that three copies of the image mura compensation data are provided.
