1. Introduction

This data sheet is to introduce the specification of LZ9GF16,

timing control IC for TFT-LCDmodule.

The functions and the uses

Timing control IC for 5” size and 5.6” size TFTlLCDmodule

Horizontal frequency driver(NTSC:600 divided frequency /PAL:604 divided frequency) and

phase comparator circuit for the PLL circuit are built in.

By adding voltage Controlled Oscillator(VC0) and LowPass Filter(LPF) to this IC to makethe

PLL circuit, following signals synchronized with input composite sync.

Signal(SYN1) and vertical sync. Signal(VIN) conforming to NTSCor PALare generated.

1) Driving signal for source driver

2) Control signal for source driver

3) Driving signal for gate driver

4) Control signal for gate driver

5) Control signal for gate driver power supply making

6) Polarity alternating signal for commonelectrode driving

7) Polarity alternating signal for video signal

8) Control signal for the backlight PWMbrightness control
