1. Introduction
a-Si TFT LCD Single Chip Driver
240RGBx320 Resolution and 262K color
ILI9341V
ILI9341V is a 262,144-color single-chip SOC driver for a-TFT liquid crystal display with resolution of
240RGBx320 dots, 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.
ILI9341V 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). 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.
ILI9341V 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. ILI9341V supports full color, 8-color display mode and sleep mode
for precise power control by software and these features make the ILI9341V 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.
