NT3967
NT3967 is TFT LCD Source Driver manufactured by Novatek.
Features n Output: 402 output channels n 6-bit resolution /64 gray scales 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: 3 m A General Description
The NT3967 is a data driver IC for a color TFT LCD panel, SVGA(800- 600) and UXGA(1600- 1200) 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. 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
