Abstract
The invention discloses a method for correcting screen display based on negative feedback. Correction of the G channel value, the B channel value and the R channel value in turn is marked as a correction of the working parameters of the screen. Measuring if the luminance, color temperature y-axis coordinate and color temperature x-axis coordinate of the screen display simultaneously reach the corresponding target values after correcting the working parameters for one time; if yes, the current gray scale correction is ended; otherwise, correcting the working parameters of the current gray scale again by starting from correction of the G channel value. The R channel value, the G channel value and the B channel value are corrected in a separate manner based on the feedback, and the correction process is simplified, such that the accuracy of a single correction is higher and the correction speed is improved.
