All about Light Emitting Diodes and Organic LEDs. How they work, the difference between them. We go to the Moser Baer lab to look at OLEDs under review. Learn about the inventors of the lights at the end of the program. LEDs use pn junctions where holes and free electrons combine to form a photon at the boundary between the p and n type materials. The OLED uses thin organic (molecule with carbon) layers evaporated or deposited on a flat substrate material. The LED was invented in 1961 at Texas Instruments and the first OLED was developed at Kodak in the 1980s.
Organic Light Emitting DiodesOrganic Light-Emitting Diode technology, also abbreviated OLED, is relatively new but very promising, especially what concerns design of data display devices. OLEDs' main difference from other LEDs is that they are made of organic compounds which emit light in response to an electric current. This feature determines their main properties.OLEDs are made of special thin-film multilayer structures. These layers are special polymers. There is anode and cathode. Electrons can flow between them. When positive voltage is applied to the anode then electrons from the cathode start moving towards it. That means that the cathode emits them into the emissive layer while the anode gets them from a conductive layer. As the result of the flow of charged particles the layers a...
Organic light emitting devices, or OLEDs, are very thin (nanometer) devices made primarily with carbon-containing dye compounds. They are extemely attractive due to their simplicity, flexibility, light weight, and ultrahigh efficiency. Following their invention 30 years ago, OLEDs are now exploding into the marketplace, with prospects of ultimately replacing liquid crystal displays for mobile applications, virtual and augmented reality systems, as well as monitors and in televisions. Equally exciting is their imminent entry into the world of lighting. Yet before this revolutionary technology can dominate these applications, there are still several challenges that must be overcome. These challenges include improving their useful lifetime, improving light outcoupling using cost effective and...
OLED means Organic Light Emitting Diode, is not a new technology but many advancements are going on in this field. Many companies like LG, Samsung etc. are trying to innovate this technology to shape the future for the betterment of mankind. CES provided a platform to all these companies to display their prototype on which they are working so that they can create a buzz among their potential customer. CES (Consumer Electronic Show) is an annual trade show organized by Consumer Technology Association (CTA). In CES 2017, Many companies showed their future projects. LG was one among them. But future displays of LG steal the show. Everyone looked so impressed by the OLED's displayed by LG. In this video, I explained advantages of OLED over normal LCD. I also discussed the show-stealing OLED's ...

LG Electronics sister company LG Display, world leading developer and producer of OLED showed some exciting new concepts during a media conference held in Seoul on May 19th 2015, including 1mm wallpaper OLED TV! Wouldn’t you like to have this in our living room at home? This display is still a future concept, but a nice look into the future of TV while OLED continues to make its way to the consumer market. LG Electronics have been providing Full HD OLED TV’s in big sizes to consumers in the Nordics for over 1.5 years now, and in 2015 the first 4K OLED TV’s will be sold in the Nordics.

Carbon Nanotube Driver Circuit for 6 × 6 Organic Light Emitting Diode Display. Jianping Zou et al (2015), Scientific Reports http://dx.doi.org/10.1038/srep11755 Single-walled carbon nanotube (SWNT) is expected to be a very promising material for flexible and transparent driver circuits for active matrix organic light emitting diode (AM OLED) displays due to its high field-effect mobility, excellent current carrying capacity, optical transparency and mechanical flexibility. Although there have been several publications about SWNT driver circuits, none of them have shown static and dynamic images with the AM OLED displays. Here we report on the first successful chemical vapor deposition (CVD)-grown SWNT network thin film transistor (TFT) driver circuits for static and dynamic AM OLED displa...

Speaker: Hagen Klauk, PhD, Director of the Max Planck Research Group Organic Electronics, http://www.fkf.mpg.de/oe Active-Matrix Organic Light-Emitting Diode (AMOLED) displays are among the most exciting developments in consumer electronics in the past decade. 250 million AMOLED displays with a total area of 1.6 square kilometers and a total value of 12 billion Euros were manufactured in 2013, mainly for mobile phones and small tablets. Current trends in AMOLED displays include higher resolution (beyond HD), larger screen size (55 inch diagonal) and the development of flexible backplanes for rollable or foldable displays. The latter will benefit from a technology which allows the thin-film transistors (TFTs) that control the individual display pixels to be fabricated at temperatures compa...
