1.5吋 128x128 支援灰階方形OLED顯示器模組

Model No. REX128128H

這款方形 OLED 顯示器AA尺寸為 1.5 吋，模組外觀尺寸為 33.8×36.5 mm，解析度128x128 像素。 REX128128H 方形OLED模組為COG結構，內建 CH1120 IC可支援4bits灰階，OLED具有較高的對比度為10,000:1。此型號方形OLED顯示器模組有8080、SPI、I2C等多種介面可選擇。

邏輯電源電壓範圍為1.65V-3.3V，典型值為3.0V。模組工作溫度範圍為-40~80℃；儲存溫度範圍為-40~+85°C。 OLED顯示器不需要背光，因為它本身會發光，這使得OLED顯示器具有輕薄、高對比度和低功耗的特點。 REX128128H OLED 發光顏色有白色和黃色。

符號

功能說明

ESD_GND

This pin should be connected to GND.

VPP

This is the most positive voltage supply pin of the chip.
It should be supplied externally.

VCOMH

This is a pin for the voltage output high level for common signals.
A capacitor should be connected between this pin and GND.

VDD

Power supply for logic

No connection

IM1

These are the MPU interface mode select pins.

	8080	3-wire SPI	4-wire SPI	I2C
IM1	1	0	0	1
IM2	1	1	0	0

These pins must be connected to “H” or “L”.

IM2

VSS

Ground for logic and analog. This pin should be connected to GND externally.

IREF

This is a segment current reference pin.
A resistor should be connected between this pin and GND.

CSB

This pin is the chip select input. When CSB = “L”, then the chip select becomes active, and data/command I/O is enabled.
When in I2C interface, this pin is not used, so it must be connected to “L”.

RESB

This is a reset signal input pin. When RESB is set to “L”, the settings are initialized. The reset operation is performed by the RESB signal level.
This pin internal pull high.

This is the Data/Command control pin that determines whether the data bits are data or a command.
A0 = “H”: the inputs at D0 to D7 are treated as display data.
A0 = “L”: the inputs at D0 to D7 are transferred to the command registers.
In I2C interface, this pin serves as SA0 to distinguish the different address of OLED driver.
When in 3-wire interface, this pin is not used, so it must be connected to “L”.

WRB

This is a MPU interface input pin.
When connected to an 8080 MPU, this is active LOW. This pin connects to the 8080 MPU WR signal. The signals on the data bus are latched at the rising edge of the WR signal.
When in 3-wire.4-wire & I2C interface, this pin is not used, so it must be connected to “L”.

RDB

This is a MPU interface input pin.
When connected to an 8080 series MPU, it is active LOW. This pin is connected to the RD signal of the 8080 series MPU, and the data bus is in an output status when this signal is “L”.
When in 3-wire.4-wire & I2C interface, this pin is not used, so it must be connected to “L”.

This is an 8-bit bi-directional data bus that connects to an 8-bit or 16-bit standard MPU data bus.
When the serial interface(SPI) and I2C is selected, then D0 serves as the serial clock input pin (SCL) and D1 serves as the serial data input pin (SI). At this time, D2 to D7 are set to high impedance. D7~D2 is recommended to connect the VDD or GND. It is also allowed to leave D7~D2 unconnected.

VPP

This is the most positive voltage supply pin of the chip.
It should be supplied externally.

ESD_GND

This pin should be connected to GND.
