General Description
The NT3967 is a data driver IC for a color TFT LCD panel, SVGA(800*600) and UXGA(1600*1200) applications. For better
performance, dot inversion and a wide range voltage output are designed in this chip and for reducing EMI, data inversion
control is used. This chip supplies 10 sections of voltage-reference for Gamma correction.
