S6D0110 132 RGB SOURCE & 176 GATE DRIVER WITH INTERNAL RAM FOR 65K COLORS TFT-LCD
Preliminary

INTRODUCTION
The S6D0110 is 1-chip solution for TFT-LCD panel: source driver with built-in memory, gate driver, power IC are
integrated on one chip. This IC can display to a maximum of 132-RGB x 176-dot graphics on 65k-color TFT panel.
The S6D0110 also supports bit-operation functions, 8/16-bit high-speed bus interface, and high-speed RAM-write
functions enable efficient data transfer and high-speed rewriting of data to the internal GRAM.
The moving picture area can be specified in internal GRAM by window function. The specified window area can be
updated selectively so that moving picture is able to displayed simultaneously independent of still picture area.
The S6D0110 has various functions for reducing the power consumption of a LCD system: It operates at low voltage
(minimum 1.8V) and the IC has an internal GRAM to store 132-RGB x 176-dot 65k-color image. In addition, it has
the internal booster that generates the LCD driving voltage, breeder resistance and the voltage follower circuit for
LCD driver.
This LSI is suitable for any medium-sized or small portable mobile solution requiring long-term driving capabilities,
such as digital cellular phones supporting a web browser, bi-directional pagers, and small PDAs.
