General Description
The NT3980 is a data driver IC for a color TFT LCD panel, XGA and SXGA applications. It receives 8 bit per-pixel digital display
data,and generates output voltage for 256 grayscales ,enabling a maximum of 16.77M display colors . For better performance,
dot inversion and a wide range voltage output, 10V, 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.
