Compensation method of mura phenomenon of curved liquid crystal panel

A compensation method of Mura phenomenon of a curved liquid crystal panel, comprising steps of:

• step 1, providing the curved liquid crystal panel and a camera, and shooting the curved liquid crystal panel of showing an image with the camera, and obtaining image Mura compensation data of the curved liquid crystal panel according to a collected image;
• the image Mura compensation data comprises:
• a Mura compensation value and a compensation point location corresponded with the Mura compensation value, and the compensation point location is a location of a compensation point in the collected image of the camera;
• step 2, implementing correction to the compensation point location in the image Mura compensation data obtained in the step 1 to acquire a compensation point location after correction, and the compensation point location after correction is a position of the compensation point in a plane development diagram of the curved liquid crystal panel, and the compensation point location after correction 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;
• step 3, implementing Mura compensation to the curved liquid crystal panel according to the plane Mura compensation data obtained in the step 2;
• wherein in the step 1, the camera is in a fixed position for shooting the LCD panel;
• wherein in the step 1, 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, and there are three copies of the obtained image Mura compensation data.
