Abstract: A method for correcting color characteristics of a flat panel display comprises the steps of using a signal generating device to generate an input signal to the display and a color measurement instrument to measure color displayed by the display to obtain an output value; obtaining corrected color characteristic values necessary for the display to display a target output value Txyz through the relation of an inverse function RGB=f?1(XYZ) between the input signal RGB and output value XYZ, and storing the corrected color characteristic values and an identification code of the display into a storage medium. The corrected color characteristic values are downloaded to a hard disk of a computer from the storage medium according to the identification code; and the computer uses a driver of the display to activate the flat panel display to display a corrected color according to the corrected color characteristic values.

Abstract: The present invention discloses a method and an apparatus for correcting color mixing errors, which lets a color display device adopt a virtual material quantity concept and use at least one set of predetermined virtual primary colors to analyze mixed color signal values displayed on the color display device and establish a corresponding material characteristic functions between color control signal values and corresponding virtual control signal values, and eventually establish nonlinear color correction functions between a series of known control signal values corresponding to desired color signal values of the color display device, in such a way that when the color display device performs a video color conversion, the control signal values actually entered into the color display device are corrected to the corresponding target control signal values for allowing the color display device to display desired color signal values.
