An organic light-emitting diode (OLED or Organic LED), also known as an organic EL (organic electroluminescent) diode, is a light-emitting diode (LED) in which the emissive electroluminescent layer is a film of organic compound that emits light in response to an electric current.

An OLED display works without a backlight because it emits visible light. Thus, it can display deep black levels and can be thinner and lighter than a liquid crystal display (LCD). In low ambient light conditions (such as a darkroom), an OLED screen can achieve a higher contrast ratio than an LCD, regardless of whether the LCD uses cold cathode fluorescent lamps or an LED backlight.

SSD1306 is a single-chip CMOS OLED/PLED driver with a controller for organic/polymer light-emitting diode dot-matrix graphic display system. It consists of 128 segments and 32 commons. This IC is designed for the Common Cathode type OLED/PLED panel. The SSD1306 embeds with contrast control, display RAM, and oscillator, which reduces the number of external components and power consumption. It has 256-step brightness control. A major area of research is the development of white OLED devices for use in solid-state lighting applications.

OLEDs are used to create digital displays in devices such as television screens, computer monitors, portable systems such as smartphones, handheld game consoles, and PDAs.
