1.5 inch OLED Display Module, OLED 1.5 inch

Model No. REA128128A

REA128128A is a graphic COG OLED display module with resolution 128x128 pixels. Module size is 34.2x45.5 mm; Active area size is 26.86x26.86 mm (1.5 inches diagonal). The additional PCB on this 1.5” 128x128 OLED display allows users to connect cables and save time on developing PCB on their own.

To make the module more user-friendly, we've also integrated the setting of interface and VCC circuit. There are 4 screw holes on the PCB for easy assembly and quick mounting. This OLED module has built-in IC SSD1327 supporting 4-line SPI/I2C interfaces. Our OLED boasts high contrast ratio 10,000：1 making the visual performance stand out from traditional displays. The module works within temperature from -40℃ to +80℃; Storage temperature range is -40℃ to + 85℃.

Raystar provides three OLED emitting colors for you to choose from: white, yellow, and sky blue. On top of it, it also supports grayscale. REA128128A is a good fit for applications such as smart home appliances, medical equipment, dashboards, etc.

No. Symbol Function
1 GND This is a ground pin.
2 VCC Power supply for panel driving voltage. This is also the most positive power voltage supply pin. It is supplied by external high voltage source.
3 D0 These pins are bi-directional data bus connecting to the MCU data bus.
Unused pins are recommended to tie LOW.
When serial interface mode is selected, D0 will be the serial clock input: SCLK; D1 will be the serial data input: SDIN and D2 should be kept NC.
4 D1
5 RES# This pin is reset signal input.
When the pin is pulled LOW, initialization of the chip is executed.
Keep this pin pull HIGH during normal operation.
6 D/C# This pin is Data/Command control pin connecting to the MCU.
When the pin is pulled HIGH, the data at D[7:0] will be interpreted as data.
When the pin is pulled LOW, the data at D[7:0] will be transferred to a command register.
7 CS# This pin is the chip select input connecting to the MCU.
The chip is enabled for MCU communication only when CS# is pulled LOW (active LOW).
