0.96 inch white OLED display module. The display module can be interfaced with any microcontroller using SPI/IIC protocols. It is having a resolution of 128x64 . The package includes display board,display, 6 pin male header presoldered to board. OLED (Organic Light-Emitting Diode) is a self light-emitting technology composed of a thin, multi-layered organic film placed between an anode and cathode. In contrast to LCD technology, OLED does not require a backlight. OLED possesses high application potential for virtually all types of displays and is regarded as the ultimate technology for the next generation of flat-panel displays. OLEDs basic structure consists of organic materials positioned between the cathode and the anode, which is composed of electric conductive transparent Indium Tin Oxide (ITO). The organic materials compose a multi-layered thin film, which includes the Hole Transporting Layer (HTL), Emission Layer (EML) and the Electron Transporting Layer (ETL). By applying the appropriate electric voltage, holes and electrons are injected into the EML from the anode and the cathode, respectively. The holes and electrons combine inside the EML to form excitons, after which electro luminescence occurs. The transfer material, emission layer material and choice of electrode are the key factors that determine the quality of OLED components.

One problem with using a typical LCD display is that you give up a lot of GPIO pins to talk to the LCD. Four pins are used to send data, two pins are used for write and clock signals, and another pin or three are used for the backlight for a total of ~6-9 total pins! With an integrated MCP23017 16-bit IO port expander you can add a full display capability to your project with only 2 pins of the I2C port. The 16×2 translates of a display 16 characters per line in 2 such lines.
