Abstract
The invention provides a method for storing compensation table of OLED display panel, by obtaining the first and second sub-pixel compensation tables and defining the first sub-pixel compensation table as the benchmark table, and containing at least a calibration table based on the first and second sub-pixel compensation tables and a default compensation table translation formula, and guaranteeing the sum of the information entropy of the calibration tables being less than the information entropy of the second sub-pixel compensation table, and storing the compressed benchmark table and calibration table. As such, the present invention can eliminate the correlation among different sub-pixel compensation table before compression to achieve better compression efficiency and smaller size, the system storage space occupied by the compensation table is reduced and the time of transmitting and burning data on production line is shortened.
