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 www.DataSheet4U.com used. This chip supplies 10 sections of voltage -reference for Gamma correction.
