0.96in 6 pin OLED Display This is the 0.96 inches (2.44 cm) OLED Display Module is a precise small, This OLED module can be interfaced with any microcontroller using SPI protocol. It is having 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. OLED 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 OLED 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 form a multi-layered thin film that includes the Hole Transporting Layer (HTL), Emission Layer (EML), and Electron Transport 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. It can be used with either an SPI or a USB interface, which can be selected by soldering two jumpers on the back. The design is entirely 5v-geared, with an onboard regulator and built-in raise converter. It's now easier than ever to connect your 3v or 5v microcontroller without the use of a stage shifter. If you want to use this OLED display module in your Arduino project, for that you will need few essential components like Jumper wires Breadboard Batteries or power supply
