Abstract:
A method for regulating brightness and chromaticity of a display panel includes: obtaining original gray-scale data; regulating gray-scales of green, so that brightness values of pixels match a standard gamma curve; matching color coordinates of red and blue using the gray-scales of green; determining a weight coefficient according to a gradation of the gray-scales of green; and calculating and recording color coordinates of target gray-scales of red and blue using the determined weight coefficient.
