Title: BRIGHTNESS COMPENSATION METHOD OF MURA REGION AND METHOD OF DESIGNING BRIGHTNESS OF MURA PIXEL
Abstract:
A brightness compensation method of a Mura region and method of designing the brightness of a Mura pixel. The method comprises: searching for most proximate normal pixels on the right of and below a specified Mura pixel, and respectively recording the brightness of the normal pixels on the right of and below the specified Mura pixel and the distances of said normal pixels to the specified Mura pixel; combining the brightness of proximate normal pixels on the left of and above the specified Mura pixel, performing weighted computation on the brightness of the normal pixels on the right of, below, on the left of and above the specified Mura pixels by using distances as weights, so as to obtain ideal brightness of the specified Mura pixel; and replacing the original brightness of the specified Mura pixel with the obtained ideal brightness, such that brightness compensation of a Mura region can be completed. The method achieves a smooth brightness transition in a compensated Mura region.
