General Description
The NT3966 is a data driver IC for a color TFT LCD panel, SXGA+(1400*1050) applications. For better performance, dot
inversion and a wide range voltage output have been designed into this chip, and for reducing EMI, data inversion control has
been incorporated. This chip supplies 10 sections of voltage-reference for Gamma correction.
