Problems solved by technology
The above optical defects will not affect the use, but will affect the taste of the display
[0003] The known optical compensation (DeMura) system only compensates for the imaging of a single angle of view, that is, it only corrects a single compensation value for a single angle
However, the imaging and changes of optical defects at side view angles are different from those at front view angles, and cannot be improved by a single compensation value at a single angle, and the imaging of optical defects at different gray scales is different, and cannot be improved by a single compensation value

An optical compensation system of a display and an optical compensation method thereof. The optical compensation method includes the following steps. The display panel of the display is photographed by a camera to obtain plane data of the display. The planar data is utilized by a processor of the host to generate first baseline data. The processor uses at least one mask pattern to mask the first baseline data to generate second baseline data. The processor uses the first baseline data and the second baseline data to superimpose to generate the third baseline data. A coefficient data is calculated by the processor using the third baseline data. The processor uses the coefficient data to set the look-up table of the display to set the display effect of the display.
Description
technical field [0001] The invention relates to an optical compensation technology, and in particular to an optical compensation system of a display and an optical compensation method thereof. Background technique [0002] With the advancement of semiconductor technology, the size of the display panel of the display is getting bigger and bigger, but with various process defects, the display panel may have various optical defects (mura). The above-mentioned optical defects will not affect the use, but will affect the display taste of the display. [0003] The known optical compensation (DeMura) system only compensates for the imaging of a single viewing angle, that is, only corrects a single compensation value for a single viewing angle. However, the imaging and changes of optical defects at side view angles are different from those at front view angles, and cannot be improved by a single compensation value at a single angle, and the imaging of optical defects at different g...
