Abstract

Disclosed here is a method of color matching of TFT-LCD panels. TFT-LCD panels are composed of Liquid Crystal Cell, Source line driver IC, Gate line driver IC, Timing controller, DCDC converter and analogue circuit to generate several reference voltages etc. Source line driver IC has many input terminals of digital data and analogue reference voltage (VREFs) like fig.1.
