OLED 1.3 inch 4pin RG128x64 Display Blue

This 4-pin RG128x64 display is an OLED module measuring 1.3 inches in blue. It can be easily connected to any microcontroller through SPI/IIC protocols. With a resolution of 128x64, this package contains a display board, display, and pre-soldered 4-pin male header. OLED (Organic Light-Emitting Diode) technology, composed of a thin, multi-layered organic film sandwiched between an anode and cathode, is self-luminescing and eliminates the need for a backlight. Known for its high application potential, OLED is considered to be the superior technology for flat-panel displays. Its organic materials, including the Hole Transporting Layer (HTL), Emission Layer (EML), and Electron Transporting Layer (ETL), are held between a transparent, electrically conductive anode made of Indium Tin Oxide (ITO) and a cathode. By applying a specific electric voltage, the EML
