  • Compensation method of Mura phenomenon
    Patent number: 9747851
    Abstract: The present invention provides a compensation method of Mura phenomenon. By dividing the LCD display panel into a plurality of display partitions, and selecting a pre-selected pixel dot of a determined position in each display partition and obtaining gray scale compensation data thereof at the respectively selected gray scales, and then, calculating the respective interpolation coefficients of the requested pixel dots in the corresponding display partitions, the compensation data of partial pixel dots in the respective gray scales and the respective interpolation coefficients of the requested pixel dots can be utilized to calculate the gray scale compensation data of all pixel dots in all gray scales. The calculation difficulty is reduced to lower the computation. The consumption of the hardware storage space is decreased and the Mura compensation result can be ensured. The time and effort can be saved and it can be simple and quick.
