a-Si TFT LCD Single Chip Driver
320RGBx480 Resolution and 262K color
ILI9481
1. Introduction
ILI9481 is a 262,144-color single-chip SoC driver for a-TFT liquid crystal display with resolution of 320RGBx480
dots, comprising a 960-channel source driver, a 480-channel gate driver, 345,600 bytes GRAM for graphic data
of 320RGBx480 dots, and power supply circuit.
The ILI9481 supports 18-/16-/9-/8-bit data bus interface (DBI) and serial peripheral interfaces (SPI). It also
supplies 18-bit, 16-bit or 6-bit RGB interface (DPI) for driving video signal directly from application controller. 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.
ILI9481 can operate with 1.65V I/O interface voltage, and an incorporated voltage follower circuit to generate
voltage levels for driving an LCD. The ILI9481 also supports a function to display in 8 colors and a sleep mode,
allowing for precise power control by software and these features make the ILI9481 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.
