4. Function Specifications

4.1 Basic Setting

To drive the LCD module correctly and provide normally display, please use the following setting

- Internal Oscillator = ON

- DC-DC Booster (VB)= ON

- Voltage Follower (VF) = ON

- Reference Voltage (VR) = ON

- Clock Divider (CL) = ½

- Driver duty = 1/160

- FI = 0

- FR Inverse-Set Value (LF) = 0

- COMMON Scan Mode = 001(binary)

- Direction of the Line Address (LI) = Inverse

- Direction of the Column Address (CL) = Normal

- Address-scan direction (C/L) = column direction

- P1, P2, P3 arrangement (CLR) = Normal (P1, P2, P3)

- Gray Scale Display Mode = 3Bit per 3Pixel mode

- OSC Frequency = 19.3kHz

- Booster Efficiency Set = 00(binary)

- LCD Bias Set = 1/12

- Display ON/OFF = ON

Note:

*1. These setting/commands should issue the LCD module while start up.

*2. See the Display Commands section for details.

4.2 Resetting the LCD module

The LCD module should be initialized by using /RST terminal.

While turning on the VDD and VSS power supply, maintain /RST terminal at LOW level.

After the power supply stabilized, release the reset terminal (/RST=HIGH)

Pixel mapping (Top View)

Based on the top view of the LCD module,

X = COLUMN, Y = Line

0, 0 (x, y) pixel is the upper-left pixel;

239, 159 (x, y) pixel is the lower-right pixel.

Note:

4.4.5 Power off the LCD Module

It recommends that enter sleep mode before power off the LCD module.

4.4.6 Refreshing The LCD Module

It recommends that the operating modes and display contents be refreshed periodically to prevent

the effect of unexpected noise.

4.4.7 Using Read EEPROM function for contrast

It recommends to use EPMRD function to ensure the contrast consistencyin batch.

Please refer to ST7529 datasheet for the details of operation.
