1. A method for compensating a brightness error of a flat panel display, comprising:

  • inputting a series of gray level signals (Gray) to a flat panel display under a fixed sustain frequency (fs), and measuring an output brightness of said flat panel display to obtain an actual output brightness Ymea (fs Gray);

    calculating an ideal output brightness Yideal (fs, Gray) corresponding to said gray level according to the linear proportional relation between said input gray level and said ideal output brightness;

    creating a look up table according to said actual output brightness Ymea (fs Gray) and said ideal output brightness Yideal (fs, Gray), and said look up table comprises a series of converted gray levels (Gray′

    ) and actual output brightness Ymea (fs Gray′

    ) corresponding to each of said converted gray levels, and said actual output brightness Ymea (fs, Gray′

    ) corresponding to said each converted gray level is closest to said ideal output brightness Yideal (fs, Gray) of said each input gray level, such that when a gray level is going to be inputted to said flat panel display, said look up table will be used to look up a corresponding converted gray level according to said gray level in advance and said converted gray level will be inputted to said flat panel display, so as to allow said flat panel display to output a gray level brightness closest to said ideal output brightness Yideal (fs, Gray).
