AMOLED
display technology for use in mobile devices and televisions
Active-matrix organic light-emitting diode (AMOLED) screens are 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.
Since 2010, AMOLED displays have been used in mobile phones, media players, TVs, and digital cameras. Development of the technology focuses on reducing power usage, lowering manufacturing costs, and increasing screen resolutions (e.g., 8K).
Design
An AMOLED display consists of an active matrix of OLED pixels generating 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.
Typically, this continuous current flow is controlled by at least two TFTs at each pixel (to trigger the luminescence), with one TFT to start and stop the charging of a storage capacitor and the second to provide a voltage source at the level needed to create a constant current to the pixel, thereby eliminating the need for the very high currents required for passive-matrix OLED operation.
TFT backplane technology is crucial in the fabrication of AMOLED displays. In AMOLEDs, the two primary TFT backplane technologies, polycrystalline silicon (poly-Si) and amorphous silicon (a-Si), are currently used offering the potential for directly fabricating the active-matrix backplanes at low temperatures (below 150 °C) onto flexible plastic substrates for producing flexible AMOLED displays.
History
AMOLED display research was initiated by Steven Van Slyke and Ching Wan Tang, who pioneered the organic light-emitting diode (OLED) technology at Eastman Kodak Co. in 1979.
The public source identifies “AMOLED” as display technology for use in mobile devices and televisions. This brief keeps that definition visible, then builds a research path around AMOLED, display and technology.
Why this record matters
A short description can identify a subject without explaining its stakes. For “AMOLED”, the useful work is to connect “display technology for use in mobile devices and televisions” to the records capable of establishing context and consequence.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Sep 4, 2026. The linked authority identifier is Q527747. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2010 and 1979.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
