Active-matrix OLED. AMOLED (active-matrix organic light-emitting diode) is a display technology for use in mobile devices and televisions.
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. As of 2012[update], AMOLED technology is used in mobile phones, media players and digital cameras,[1] and continues to make progress toward low-power, low-cost and large-size (for example, 40-inch) applications.[2][3][4] Design[edit] Schematic of an active-matrix OLED display An AMOLED display consists of an active matrix of OLED pixels that generate light (luminescence) upon electrical activation that have been deposited or integrated onto a thin-film-transistor (TFT) array, which functions as a series of switches to control the current flowing to each individual pixel.[5] TFT backplane technology is crucial in the fabrication of AMOLED displays.

Future development[edit] Amoled. Een amoled-scherm (active-matrix organic light-emitting diode) is een technologie die voortkomt uit oled-schermen.
Werking[bewerken] Een amoled-scherm bestaat uit oled-pixels die verwerkt zijn in een thin film transistor (tft). De pixels kunnen geïntegreerd zijn in de dunne laag van de tft of hierop geplaatst zijn. De pixels zijn zo gerangschikt dat ze een rooster van pixels vormen. Tussen de tft-laag en de kathodelaag is er een laag met organisch materiaal dat zal oplichten als er een elektrische activering plaatsvindt. Voordelen[bewerken] Nadelen[bewerken] Het grootste nadeel van amoled-schermen is het feit dat het een complex ontwikkelingsproces is. Toepassingen van amoleds[bewerken] Amoled-Son Dam Bi[bewerken] Toen Samsung de eerste mobiele telefoon met amoled op de markt bracht, zorgde Son Dam bi met het liedje 'Amoled' voor de promotie in Zuid-Korea. What is AMOLED? AM-OLED means Active matrix organic light emitting diode; an OLED Display is a series of organic thin films between two conductors.
If electric current is applied in a pixel, light is emitted. Every single pixel will be activated (electrical) via a Thin Film Transistor TFT array. To start the luminescence of one pixel the manufacturer uses two TFTs. There are two Thin Film backplane technologies: Polycrystalline Silicon (poly-Si)Amorphous Silicon (a-Si) Both of these TFT technologies have the advantage that they can produce the backplanes at a temperature under 160 Celsius.
One of the key points to note is that an Organic light emitting diode does not have to be a backlight like LCD. What kind of products can be produced with OLED?
