Description

Summary

OLED display modules with different specifications and driver circuits, which can be driven in your circuit through the IIC or SPI bus. The drive board has integrated auto reset circuit, IIC bus pull-up resistor, boost charge pump, and other functional units, ensuring that the module can operate stably for a long time.

Main Features

Display Resolution: 128 x 64;
Onboard power-on reset circuit；
I2C (2.54 x 4) or SPI (2.54 x 6) interface optional;
1.0 x 4 FFC footprint (I2C only);
Default I2C address: 0x3C, for some MCU with 8-bit I2C register, the I2C address should be 0x78 (0x3C << 1).

Description

High light

Flexible installation

4 elliptical fixed holes (fit M2 screw), makes it can flexibly fit to your product shell.

External charge pump

The 1.3“ IIC comes with an external charge pump version to ensure sufficient power supply for the LCD panel and more stable modules,

Organic electroluminescence display

Compared to traditional LCDs, the pixel units of OLED displays are self illuminating and no longer use backlight, which makes their imaging performance better, especially in strong light environments such as direct sunlight, where the display effect is much better than LCD displays.

FAQ

What is the maximum rate of communication between IIC and SPI?

Both IIC and SPI, the maximum communication rate is 400 KHz.

If one corner of the display screen breaks, can it still work properly?

No, the LCD panel of OLED is a whole. If one of its corners is broken, it will affect the integrity of its panel and will no longer be able to display normally. Can cause incomplete display images.

Is there a complete protective packaging when purchasing in bulk?

Yes, for customers who buy in bulk, we will provide special EPE foam protective packaging

What is the working life？

The theoretical data is over 30,000 hours.
