1. Introduction
The GC9307 is a 262,144-color single-chip SOC driver for a-TFT liquid crystal display with
resolution of 240RGBx320dots, comprising a 720-channel source driver, a 320-channel gate
driver, 172,800 bytes GRAM for graphic display data of 240RGBx320 dots, and power supply
circuit.
The GC9307 supports parallel 8-/9-/16-/18-bit data bus MCU interface, 6-/16-/18-bit data bus
RGB interface and 3-/4-line serial peripheral interface (SPI) and 2 lane SPI data transmission.
The moving picture area can be specified in internal GRAM by window address function. The
specified window area can be updated selectively, so that moving picture can be displayed
simultaneously independent of still picture area.
The GC9307 can operate with 1.65V ~ 3.3V I/O interface voltage and an incorporated voltage
follower circuit to generate voltage levels for driving an LCD. GC9307 supports full color,
8-color display mode and sleep mode for precise power control by software and these features
make the GC9307 an ideal LCD driver for medium or small size portable products such as digital
cellular phones, smart phone, MP3 and PMP where long battery life is a major concern.
