1. 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, green, and blue light emitting diodes (LEDs) 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, green, and blue LEDs 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, green, and 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, green, and blue LEDs referring to differences between the second and fourth matrices.
