CSTN LCD DRIVER IC UC1693v

Single-Chip, Ultra-Low Power
96COM x 96RGB Matrix
Passive Color LCD Controller-Driver
with VSTN Support
INTRODUCTION
UC1693v is an advanced high-voltage mixedsignal
CMOS IC, specially designed for the
display needs of low power hand-held devices.
In addition to low power COM and SEG drivers,
UC1693v contains all necessary circuits for
high-V LCD power supply, bias voltage
generation, temperature compensation, timing
generation, and graphics data memory.
UC1693v employs UltraChips 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
while supporting very fast Liquid Crystal material
for video applications.
With UC1693v, LCD makers can now achieve
TFT-like image quality, support video applications
while maintaining the same STN advantages in
power consumption, unit cost, ease of
customization and production flexibility.
MAIN APPLICATIONS
Cellular Phones and other battery operated
hand held devices or portable instruments
