This is the 1.3-inch blue OLED display module. Using I2C protocols, the display module can communicate with any microcontroller. It has a resolution of 128x64. OLED (Organic Light-Emitting Diode) is a self-lighting technology that consists of a thin, multi-layered organic film sandwiched between an anode and a cathode.
OLED, unlike LCD technology, does not require a backlight. This has a wide range of applications and is widely regarded as the ultimate technology for the next generation of flat-panel displays.
The basic structure of an display module is made up of organic materials sandwiched between the cathode and the anode, which is made of electric conductive transparent Indium Tin Oxide (ITO).
The organic materials combine to form a multi-layered thin film that includes the Hole Transporting Layer (HTL), Emission Layer (EML), and Electron Transporting Layer (ETL) (ETL). By applying the appropriate electric voltage, holes and electrons from the anode and cathode are injected into the EML.
Inside the EML, holes, and electrons combine to form excitons, which cause electroluminescence. The key factors that determine the quality of OLED components are the transfer material, emission layer material, and electrode selection.
If you want to use this 1.3 inch OLED display module in your Arduino project, that you will need a few essential components like
