OLED stands for Organic Light-Emitting Diode (Organic Light-Emitting Diode), also known as Organic Electroluminesence Display (OELD). OLED is considered to be the most advanced technology due to its self-illumination, no need for backlight, high contrast, thin thickness, wide viewing angle, fast response speed, flexible panel, wide operating temperature range, and simple structure and manufacturing process. Next-generation flat-panel display emerging application technology. OLED display technology has the characteristics of self-illumination. It uses very thin organic material coating and glass substrate. When current passes through, these organic materials will emit light. Moreover, OLED display screen has a large viewing angle and can save power. Since 2003 This display device has been used in MP3 players since 1990. LCDs all need a backlight, OLED doesn't because it's self-illuminating. In this way, the same display, the OLED effect is better.
Some information and precautions about the OLED screen
1) The module is available in single-color and double-color, the single-color is pure blue, and the double-color is yellow-blue. Each pixel of the monochrome module has only two situations: on and off, and there is no color distinction.
2) The size is small, the display size is 0.96 inches, and the size of the module is only 27mm 26mm.
3) High resolution, the resolution of this module is 128 64.
4) A variety of interface methods, the module provides a total of 4 interfaces including: 6800, 8080 two parallel interface methods, 4-wire through SPI interface method, and IIC interface method (only 2 wires are needed to control OLED! ).
5) No need for high voltage, just connect 3.3V directly to work.
Here I want to remind everyone that this module is not compatible with the 5.0V interface, so please be careful when using it, and don’t connect it directly to the 5V system, otherwise the module may be burned.
Take font
Use PCtoLCD2002 software to extract OLED fonts.

Hardware IIC control mode
Features of hardware IIC communication:
1. The speed of hardware IIC is faster than analog, and the speed can reach 300KHz.
2. The hardware IIC is relatively stable.
