History[ edit ] Discoveries and early devices[ edit ] Green electroluminescence from a point contact on a crystal of SiC recreates Round 's original experiment from Electroluminescence as a phenomenon was discovered in by the British experimenter H. Round of Marconi Labsusing a crystal of silicon carbide and a cat's-whisker detector.
OLED Organic Light Emitting Diodes is a flat light emitting technology, made by placing a series of organic thin films between two conductors. When electrical current is applied, a bright light is emitted.
OLEDs are emissive display that do not require a backlight and so are thinner and more efficient than LCD displays which do require a white backlight.
OLED displays are not just thin and efficient - they provide the best image quality ever and they can also be made transparentflexiblefoldable and even rollable and stretchable in the future. OLEDs represent the future of display technology! Improved image quality - better contrast, higher brightness, fuller viewing angle, a wider color range and much faster refresh rates.
Simpler design that enables ultra-thin, flexible, foldable and transparent displays Better durability - OLEDs are very durable and can operate in a broader temperature range The future - flexible and transparent OLED displays As we said, OLEDs can be used to create flexible and transparent displays.
This is pretty exciting as it opens up a whole world of possibilities: The future will bring us much more exciting displays, so stay tuned!
How do OLEDs work? An OLED is made by placing a series of organic thin films between two conductors. Click here for a more detailed view of the OLED technology. So what's organic about OLEDs? OLEDs are organic because they are made from carbon and hydrogen.
There's no connection to organic food or farming - although OLEDs are very efficient and do not contain any bad metals - so it's a real green technology.
OLEDs are used in mobile devices today because they are thin, efficient, flexible and bright. OLEDs carry a price premium over LCDs, but companies are using these displays more and more as performance increases and prices decrease.
Here's our list of products and gadgets with an OLED display. OLEDs have limited lifetime like any display, reallythat was quite a problem a few years ago.
But there has been constant progress, and today this is almost a non-issue. OLEDs can also be problematic in direct sunlightbecause of their emmissive nature.
Can OLEDs produce white lighting? Yes, OLEDs actually make for a great light source.
OLEDs offer diffuse area lighting and can be flexible, efficient, light, thin, transparent, color-tunable and more. OLEDs will probably be used in completely new lighting designs.
Many companies are already offering samples and low-volume panels, but prices are still very high as production volume is low.

Let the 1-percenters buy these first-generation panels, driving down the cost for the rest of us. Discuss: What is. For OLED panels intended to be supplied by a power source beyond the limits of Section 12, see the Supplemental Requirements for Higher Power OLED Panels, Annex a.
An OLED panel mounted within the frame structure of a fixed or portable luminaire per (b) or (c) need not comply with the requirements in this standard where the risk of fire. Organic Light Emitting Diode (OLED) Panels UL Certification Backed by more than a century of proven safety science expertise, businesses, consumers and regulatory authorities around the world recognize the trusted rigor and technical excellence of UL certifications.
AMOLED (active-matrix organic light-emitting diode, / ˈ æ m oʊ ˌ l ɛ d /) is a display technology used in smartwatches, mobile devices, laptops, 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.
A light-emitting diode (LED) is a two-lead semiconductor light source.
It is a p–n junction diode that emits light when activated. In an organic light-emitting diode, the electroluminescent material composing the emissive layer of the diode is an organic compound.
