ADJUSTMENT METHOD FOR COLOR LIQUID CRYSTAL MODULE

摘要

PROBLEM TO BE SOLVED: To provide an adjustment method for a color liquid crystal module which is devised for an easy adjustment of a white balance. SOLUTION: A brightness adjustment signal is adjusted so that a center value of a voltage variation range corresponding to any color in a status to direct a black display or in the status to direct a white display can coincide with the center value of the voltage variation range in an adjustment target set in advance for a picture signal input to the color liquid crystal driver (Fig. 1(b)). Then, a contrast adjustment signal is adjusted without changing the center value of the voltage variation range so that the voltage variation range in the above described adjustment target can coincide with an output voltage of the color liquid crystal driver (Fig. 1(c)).
