Method for adjusting white balance in a field sequential display and device thereof
A method for adjusting white balance includes generating a first matrix according to values in axes of a color gamut corresponding to optical characteristics of a plurality of first LEDs; generating a second matrix according to values in the axes of the color gamut corresponding to optical characteristics of the plurality of first LEDs while in white balance; generating a third matrix according to values in the axes of the color gamut corresponding to optical characteristics of a plurality of second LEDs; storing the first matrix, second matrix, and 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. As a result, the optical characteristics of the plurality of second LEDs can be effectively and rapidly adjusted simply referring to the differences between the second and fourth matrices.
