240RGB x 320dot, 262,144-color

TFT Controller Driver with Internal RAM

1. Introduction

NV3029S 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, GRAM for graphic display

data of 240RGBx320 dots, and power supply circuit.

NV3029S supports 8-/9-/16-/18-bit data bus parallel interface, 6-/16-/18-bit data bus RGB interface and 3-/4-wire

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.

NV3029S can operate with 1.65V ~ 3.6V I/O interface voltage and an incorporated voltage follower circuit to

generate voltage levels for driving an LCD. NV3029S supports full color, 8-color display mode and sleep mode for

precise power control by software and these features make the NV3029S 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.

2. Features

 One-chip controller driver for 240RGB x 320 dot graphics display in 262,144 colors on TFT panel

 One-chip solution for a-Si TFT panel

 System interface

– 8-, 9-, 16-, 18-bit parallel ports

– 3-/4-wire serial peripheral interface

 Moving picture display interface

– RGB interface (VSYNC, HSYNC, DOTCLK, ENABLE, DB17-0) via 6-, 16-, 18-bit ports

 Window address function to specify a rectangular area in the internal RAM to write data

– Writes data within a rectangular area on the internal RAM via moving picture interface

– Reduces data transfer by specifying the area on the RAM to rewrite data

– Enables displaying the data in the still picture RAM area with a moving picture simultaneously

 Display Colors (Color Mode)

– Full Color:262K, RGB=(666)max.,Idle Mode Off

– Color Reduce: 8-color, RGB=(111),Idle Mode On

 Low–power consumption architecture (allowing direct input of interface I/O power supply)

– 8-color display function

– Input power supply voltages: VCCIO = 1.65V ~ 3.6V(interface I/O power supply)

VCI = 2.5V ~ 3.3 V (liquid crystal analog circuit power supply)

 Driving Algorithm

‐ Dot Inversion

‐ Column Inversion

 On-Chip Power System

‐ Source Voltage (VAP to VAN): +6.4~ -4.6V
