GAMMA CURVE ADJUSTING METHOD AND DEVICE

摘要

The present disclosure provides gamma curve adjusting method and device, and the method includes: substituting a preset maximum brightness value, a preset gamma value and gray-scale values into a standard gamma curve calculation formula, to obtain brightness values corresponding to the gray-scale values; selecting N gray-scale values from the gray-scale values, and actually measuring, in the condition of the selected N gray-scale values, gray-scale voltage values required to reach brightness values, respectively corresponding to the selected N gray-scale values, calculated according to the standard gamma curve calculation formula, where N is a positive integer; obtaining a function formula between gray-scale voltage value and brightness value according to brightness values respectively corresponding to the selected N gray-scale values and the actually measured gray-scale voltage values; and calculating gray-scale voltage values corresponding to brightness values smaller than or equal to the preset maximum brightness value, according to the obtained function formula.
