General Description
The NT3965 is a data driver IC for color TFT LCD panel, XGA and SXGA 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.
