==Introduction==The growing number of electronic devices using This report presents a brief introduction to OLED (organic light emitting diode displays shows that after years of promise, the technology is increasingly finding place in many products) and technologies available for top emission OLED. But while A detailed taxonomy for OLED displays might challenge LCDs as is presented covering parts of the screens type of choice for smaller gadgets, the technology may not become mainstream for notebook PCs or TVs within this decade. OLED displays use organic compounds that emit light when exposed to an electric current. They are brighter, have better contrastmaterial used, offer wider viewing angles, use less powermanufacturing, applications among others. A detailed landscape analysis of patent and provide faster response times than liquid crystal displays. OLED screens' thickness non-patent literature is done with a third focus on Top Emission OLED (TEOLED). The product information of that major players in the market is also captured for OLED. The final section of LCDs, since they don't need a back-light, the report covers the existing and that makes them a good fit future market predictions for portable OLED.[[Image:OLED.png|right|thumb|800px| '''[http://electronics devices.howstuffworks.com/oled2.htm OLED Working Principle]]]=Introduction=Rationale==*Unlike LCDs, which require backlighting, OLED displays are "emissive" devices, meaning they emit light rather than modulate transmitted or reflected light.
*OLED technology was firstly developed in 1987 at Eastman Kodak Company by Tang and Van Slyke using small-molecule (sm-OLED). In 1990 Richard Friend, Jeremy Burroughes and Donal Bradley discovered electroluminescence capabilities from conjugated polymers so laying down the foundations for a new generation of flat panel displays.
*The growing number of electronic devices using organic light emitting diode displays shows that after years of promise, the technology is increasingly finding place in many products. But while OLED has displays might challenge LCDs as the potential to revolutionize screens of choice for smaller gadgets, the world's $100 billion lighting industry.[http://wwwtechnology may not become mainstream for notebook PCs or TVs within this decade.time.com/time/magazine/article/0,9171,2005725,00.html source]*A light source OLED displays use organic compounds that could put the traditional emit light bulb in the shade has been invented by US scientistswhen exposed to an electric current.[http://news.bbc.co.uk/2/hi/sci/tech/4906188.stm source]*OLEDs can provide They are brighter, crisper displays on electronic devices and have better contrast, offer wider viewing angles, use less power , and provide faster response times than conventional light-emitting diodes (LEDs) or liquid crystal displays (LCDs) used today.[http://OLED screens' thickness is a third of that of LCDs, since they don't need a back-light, and that makes them a good fit for portable electronicsdevices.howstuffworks.com/oled.htm source==Read More? ==Click on [[OLED Background]] to read more about OLED.
==OLED Components==[[Image:oled structureTraditional light bulbs were invented more than 130 years ago.png|thumb|center| 300 px|]]An OLED consists Since then the basic principle of creating light remains the following parts:*Substrate (clear plasticsame, glass, foil) - The substrate supports although the OLEDdesign has been tweaked.* Anode (transparent) - The anode removes electrons (adds electron "holes") when a An electric current flows passing through the devicea tungsten wire causes it to heat up and glow white hot.* Organic layers - These layers are made Today, more than 20% of organic molecules or polymers.**Conducting layer - This layer is made of organic plastic molecules that transport "holes" from the anode. One conducting polymer electricity used in OLEDs US buildings is polyaniline.**Emissive layer - This layer is made of organic plastic molecules (different ones from the conducting layer) eaten up by lights and nearly half that transport electrons from the cathode; this amount is where light is made. One polymer used in the emissive layer is polyfluorene.* Cathode (may or may not be transparent depending on the type of OLED) - The cathode injects electrons when a current flows through the device.==Working of OLED'S==[[Image:oled WORKING.png|thumb|center| 400 px|]]*OLEDs emit by traditional, incandescent light in a similar manner to LEDs, through a process called electrophosphorescencebulbs.*The process is as follows:#The battery or power supply of the device containing the OLED applies It has been a voltage across the OLED.#An electrical current flows from the cathode to the anode through the organic layers (an electrical current is a flow long-term goal of electrons).#* The cathode gives electrons scientists to the emissive layer of organic molecules.#* The anode removes electrons from the conductive layer of organic molecules. (This is the equivalent to giving electron holes to the conductive layer.)#At the boundary between the emissive and the conductive layers, electrons find electron holes.#* When an electron finds an electron hole, the electron fills the hole (it falls into an energy level of the atom come up with something that's missing an electron).#* When would reduce this happens, the electron gives up mammoth energy in the form of a photon of light (see How Light Works).# The OLED emits light.# The color of the light depends on the type of organic molecule in the emissive layer. Manufacturers place several types of organic films on the same OLED to make color displays.# The intensity or brightness of the light depends on the amount of electrical current applied: the more current, the brighter the lightdemand.
==OLED Types==There are several types of The OLEDs * Passive-matrix OLED * Active-matrix OLED * Transparent OLED * Top-emitting OLED * Bottom-emitting OLED* Foldable OLED * White OLED do not heat up like today's light bulbs and so are far more energy efficient and last longer.They also produce a light that is more akin to natural daylight than traditional bulbs. The new polymer uses a fluorescent blue material instead which lasts much longer and uses less energy.
===Passive-matrix Top Emission OLED - PMOLED==: Search Strategy=PMOLEDs have strips of cathode, organic layers and strips of anode. The anode strips are arranged perpendicular to present study on the cathode strips. The intersections of IP activity in the cathode and anode make up the pixels where light is emitted. External circuitry applies current to selected strips area of anode and cathode, determining which pixels get turned OLED with focus on and which pixels remain off. Again, the brightness of each pixel '''''Top Emission OLED (TEOLED)''''' is proportional to the amount of applied currentbased on a search conducted on Micropat.
PMOLEDs are easy to make, but they consume more power than other types of OLED, mainly due to the power needed for the external circuitry. PMOLEDs are most efficient for text and icons and are best suited for small screens (==Control Patents=={|border="2" cellspacing="0" cellpadding="4" width="100%"| style="background- to 3-inch diagonal) such as those you find in cell phones, PDAs and MP3 playerscolor:#4f81bd;padding:0.

| style="padding:0.079cm;"| Device for depositing patterned layers in OLED displays
| style="padding:0.079cm;"| To achieve color pixelation in OLED imaging panels, fabrication of a multicolor OLED imaging panel using a shadow masking method is used. A multicolor organic electroluminescent ("EL") medium is vapor deposited and patterned by controlling an angular position of a substrate with respect to a deposition vapor stream. The positioning an element in direct contact with a surface of a substrate can invite problems of abrasion, distortion, or partial lifting, this may cause abrasion, distortion, or partial lifting of the first-color pattern.
