The Great Potential Of LED and OLED in the near furture

According to market research SBI (SpecialistsinBusinessInformation) estimates that the global LED and OLED current size of the market has more than 5 billion U.S. dollars, while the United States alone accounts for one billion U.S. dollars market value. This compared with 2007, a full growth of over 50%. SBI further expects 2013 global LED and OLED market will reach 14 billion U.S. dollars, while the United States up to three billion U.S. dollars of the size of the market.

Why LED and OLED technology, the best potential for future growth can be one of the industries? Because the current global efforts for the green energy industry, but also a lot more than ever before. This is thanks to first half of 2008 of oil, and other resources are constantly rising prices and global climate change had a tremendous impact on human.

LED compared to traditional incandescent bulbs in the conversion of energy is also efficient. In general, LED conversion efficiency of 80%, while only 20% of incandescent lamps. For example: use of LED traffic lights than the use of incandescent traffic lights, can be reduced to 92% of energy use.

The long term, the establishment of more of the LED, or OLED application markets, then in many parts of the world will no longer need to build too many power plants, even if the global population, more and more demand for electricity and the higher the circumstances. Because the LED and OLED will be able to reduce the power consumption of each of them even users, so once the higher penetration rate of LED lighting, then the existing power plants is sufficient to meet demand.

However, SBI also warns that even if the benefits of LED and OLED so much, but its cost reduction still takes time.

So, currently impeding the popularization of LED and OLED one of the keys is the cost. Once the rapid price declines, and perhaps the market size of LED and OLED will be larger and more popular.

Taiwan is now also actively strive to create LED market. “Ministry of Economic Affairs Bureau of Energy,” has already allocated NT 2-300000000 yuan budget for LED street lamps in the standard-setting, it will start LED streetlight replacement program. According to LEDinside estimates, Taiwan’s LED market as a whole will have a size of 400-500 billion in business opportunities.

What is OLED and PLED?

OLED is short for organic light-emitting diode, a display device that sandwiches carbon-based films between two charged electrodes, one a metallic cathode and one a transparent anode, usually being glass. The organic films consist of a hole-injection layer, a hole-transport layer, an emissive layer and an electron-transport layer. When voltage is applied to the OLED cell, the injected positive and negative charges recombine in the emissive layer and create electro luminescent light. Unlike LCDs, which require backlighting, OLED displays are emissive devices – they emit light rather than modulate transmitted or reflected light.
 
OLED technology was invented by Eastman Kodak in the early 1980s. It is beginning to replace LCD technology in handheld devices such as PDAs and cellular phones because the technology is brighter, thinner, faster and lighter than LCDs, use less power, offer higher contrast and are cheaper to manufacture.

PLED is short for polymer, or polymeric, light-emitting diode, a backlighting, illumination and display technology. Polymers are substances formed by a chemical reaction in which two or more molecules combine to form larger molecules. PLEDs are thin film displays that are created by sandwiching an undoped conjugated polymer between two proper electrodes at a short distance. The polymer emits light when exposed to electricity. PLEDs enable full-spectrum color displays and are relatively inexpensive compared to other display technologies such as LCD or OLED and require little power to emit a substantial amount of light.
