Abstract
A method, an apparatus and a system for display compensation relate to the field of display technique. The method for display compensation includes: measuring luminance of each of pixels in a full-color test picture outputted from a display apparatus in a uncompensated status when the display apparatus outputs the full-color test picture; obtaining a reference luminance value according to the measured luminance values of the respective pixels; obtaining compensation coefficients for the respective pixels according to the reference luminance value and the luminance values of the respective pixels; performing a compensation and correction on signals inputted to the respective pixels respectively according to the compensation coefficients. By utilizing the method, the issue of the non-uniformity of the display effect in the display apparatus can be addressed effectively.
