Abstract :
A novel method is proposed for the normal black (NB) TFT-LCD white point adjustment. The method provides an easy way to adjust the white point by LCD gamma voltage re-setting when the LCD color filter and backlight are fixed design. An example is given to explain the method in details. The example results show that we can obtain bluish white point chromaticity coordinate deviation by slightly optimizing the gamma voltage settings.
