Patent ID: 8207919

Claim:
A method for adjusting white balance in a field sequential display (FSD) comprising: generating a first matrix according to values in axes of a color gamut corresponding to optical characteristics of at least one first red light emitting diode (LED), at least one first green LED, and at least one first blue LED respectively; storing the first matrix; generating a second matrix according to values in the axes of the color gamut corresponding to the optical characteristics of the at least one first red LED, the at least one first green LED, and the at least one first blue LED respectively while in white balance; storing the second matrix; generating a third matrix according to values in the axes of the color gamut corresponding to optical characteristics of at least one second red LED, at least one second green LED, and at least one second blue LEDs respectively; storing the third matrix; generating a calibration matrix by multiplying the second matrix with an inverse of the first matrix; generating a fourth matrix by multiplying the third matrix with the calibration matrix; and adjusting the optical characteristics of the at least one second red LED, the at least one second green LED, and the at least one second blue LED according to a calculation result corresponding to numerical differences between the second and fourth matrices.
