NT3966
NT3966 is TFT LCD Source Driver manufactured by Novatek.
Features n Output : 420 output channels n 6-bit resolution /64 gray scale n Dot inversion with polarity control n V1 ~ V10 for adjusting Gamma correction n Power for analog circuit : 6.5 ~ 10 V n Output dynamic range : 0.1 ~ AVDD-0.1V n Power consumption of analog circuit : 3m A 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. n Power for interface circuit : 2.5~3.6V n Operating frequency : 65MHz n Output deviation : 10 ~ 20m V n Data inversion for reducing EMI n Cascade function with bi-direction shift control n CMOS silicon gate ( p-type substrate ) n TCP package
