Leds are semiconducting light sources that function through electroluminescencethat is they. This organic layer is situated between two electrodes.

The oled in oled tv stands for organic light emitting diode oleds have the unusual property of being able to produce both light and color from a single diode when theyre fed electricity.
Organic light emitting diode oled screens. When people talk about organic things these days theyre usually referring to food and clothing produced in an environmentally friendly way without the use of pesticides. Oled stands for organic light emitting diode. Oled organic light emitting diodes is a flat light emitting technology made by placing a series of organic thin films between two conductors.
The basic structure of an oled is an emissive layer sandwiched between a cathode which injects electrons and an anode which removes electrons. Organic light emitting diodes devices or oleds are monolithic solid state devices that typically consist of a series of organic thin films sandwiched between two thin film conductive electrodes. An organic light emitting diode oled screen is a low power high resolution monochrome display.
The most basic difference is that each pixel provides its own. 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. Each pixel in an oled display is made of a material that glows when you jab it with electricity.
In this example we use an inexpensive 128 x 64 pixel oled screen 128 columns and 64 rows with an onboard ssd1306 controller chip as can be found on hobbyist websites. The main component in an oled display is the oled emitter an organic carbon based material that emits light when electricity is applied. Kind of like the heating elements in a toaster but.
Typically at least one of these electrodes is transparent. Oled or organic light emitting diodes are an offshoot of existing conventional led technology. When electrical current is applied a bright light is emitted.
The exception is oled. Televisions based on organic light emitting diode display technology are fundamentally different from lcd tvs. An introduction to oled displays what is an oled.
An oled is simply an led where the light is produced emitted by organic molecules.
