An organic light-emitting diode (OLED), also known as organic electroluminescent (organic EL) diode, [1] [2] is a type of light-emitting diode (LED) in which the emissive electroluminescent layer is an organic compound film that emits light in response to an electric current.
Major technologies are CRT, LCD and its derivatives (Quantum dot display, LED backlit LCD, WLCD, OLCD), Plasma, and OLED and its derivatives (Transparent OLED, PMOLED, AMOLED). An emerging technology is Micro LED. Cancelled and now obsolete technologies are SED and FED.
1987 optical micro-electro-mechanical technology that uses a digital micromirror device. While the Digital Light Processing (DLP) imaging device was invented by Texas Instruments, the first DLP-based projector was introduced by Digital Projection Ltd in 1997.

Sony unveiled Crystal LED display technology in the CES 2012. [3] [4] The following year, the company was deciding between CLED and OLED, and did not display CLED at the 2013 CES, but produced an OLED instead.

In the early 1990s, Shuji Nakamura, Hiroshi Amano and Isamu Akasaki invented blue light-emitting diodes that were dramatically more efficient than their predecessors, bringing a new generation of bright, energy-efficient white lighting and full-color LED displays into practical use and winning the 2014 Nobel Prize in Physics.
AMOLED (active-matrix organic light-emitting diode; / ˈ æ m oʊ ˌ l ɛ d /) is a type of OLED display device technology. OLED describes a specific type of thin-film-display technology in which organic compounds form the electroluminescent material, and active matrix refers to the technology behind the addressing of pixels.
