1. Introduction
a-Si TFT LCD Single Chip Driver
320RGBx480 Resolution and 262K-color
ILI9486L
ILI9486L is a 262,144-color single-chip SoC driver for a-Si TFT liquid crystal display with resolution of
320RGBx480 dots, comprising a 960-channel source driver, a 480-channel gate driver, 345,600bytes GRAM for
graphic data of 320RGBx480 dots, and power supply circuit.
The ILI9486L supports parallel CPU 8-/9-/16-/18-bit data bus interface and 3-/4-line serial peripheral interfaces
(SPI). The ILI9486L is also compliant with RGB (16-/18-bit) data bus for video image display.
ILI9486L can operate with 1.65V I/O interface voltage and support wide analog power supply range. ILI9486L
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 ILI9486L as 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.
