UC1697v
Single-Chip, Ultra-Low Power
128COM x 128RGB Matrix
Passive Color LCD Controller-Driver
INTRODUCTION
UC1697v is an advanced high-voltage mixed-
signal CMOS IC, specially designed for the
display needs of low power hand-held devices.
In addition to low power COM and SEG drivers,
UC1697v contains all necessary circuits for high-
V LCD power supply, bias voltage generation,
temperature compensation, timing generation,
and graphics data memory.
UC1697v employs UltraChip’s unique DCC
(Direct Capacitor Coupling) driver architecture
and LRM (Line Rate Modulation) gray-shade
modulation scheme to achieve well balanced
shading, vivid colors, and natural-looking images.
With UC1697v, LCD makers can now achieve
TFT-like image quality, while maintaining the
same STN advantages in power consumption,
unit cost, ease of customization and production
flexibility.
