Caption: Television screen technology. Artwork comparing two forms of flat-screen television technology. At left is a field emission display (FED) screen. At right is an organic light-emitting diode (OLED) screen. A FED screen has an array of electron beams that strike colored phosphor on the screen in front of them, producing the desired colour. An OLED screen consists of light emitting diodes (LEDs) that have an electroluminescent layer. This layer emits light when triggered by electrodes.
