Lighting industry LED is the direction of OLED is the future

Green, low carbon has become one of the main theme of technology innovation and development. February 3, 2010, general secretary Hu Jintao called for speeding up the transformation of economic development mode, improve domestic demand and the development of new and innovative industries in economic development

Use. China has begun to shift the focus of stimulus to industrial upgrading, to rely on scientific and technological progress, improve the quality of labor, management innovation to promote economic development. 37 "speed up" shows that the speech There was no parallel in history., is up to

So far, one of China's most vocal comments on how to change the way of economic development has shown that the shift in economic development has become a more pressing task. The green low-carbon economy will become economic growth,

One of the main driving force for industrial upgrading in order to truly achieve a green recovery. Core technology + scale application =LED industry king. LED has the characteristics of small volume, high luminous efficiency, low power consumption, long service life, high safety and reliability, energy saving and environmental protection

It is the best alternative to the traditional light source of green lighting, is considered to be one of the greatest inventions invented by Edison after the incandescent bulb. China's semiconductor lighting production enterprises more than 3000, of which the focus of 70%

In the downstream industry, and the technical level and product quality uneven. At present, China can batch production of chips and epitaxial films only 10 companies, and domestic LED epitaxial materials, chips in the low - based, more than 80% of the work

Rate LED chip, device dependent imports. IC lighting driver is still in the domestic R & D stage, there is no certain scale, there is no drive IC, LED lighting bulb into the homes of ordinary people. LED industry has three types of enterprises

The industry has a high investment value: the core intellectual property rights and the LED chip industry and technology tracking more successful enterprises; excellent downstream packaging and focus on the future of the LED general lighting business; LED

Industrial chain in the field of electronic materials and drive chip companies with economies of scale. A shares of listed companies to focus on the production of the core material of the upper reaches of the rich thermoelectric, LED system integration of the core competitiveness of the larger set

Group, with LIAN LED complete industrial chain.

OLED will be the future of the lighting star. The OLED is an organic light emitting display, which does not need a backlight, can emit light by itself, and has the advantages of high visibility, high brightness, thinner thickness and relatively simple structure

With flexible substrate, it can be changed into different shapes, known as the "dream display". If LED is the future direction of development, then OLED is the future of the future. There is no commercial OLED lighting products

Listed, the key lies in its high cost. It is expected that by 2020, due to OLED lighting brightness, luminous efficiency, price, etc. will be closer to the LED, will be accepted by the general lighting market consumers, the market size will reach

8 billion U.S. dollars, accounting for the proportion of the overall lighting market is about more than 1. 2008 OLED display flat panel display market share of less than 1%, is expected in 2015 will reach 5%, the annual compound growth rate reached

40%, much higher than the flat panel display market growth of 3%. A shares of listed companies are recommended to focus on the development of OLED leader in Sichuan Changhong, followed by OLED technology can focus on the field of high-tech research in the field of Nanjing.

Risk factors: whether LED or OLED field, the vast majority of the company has not yet achieved the production of related products, the future contribution of huge uncertainty.

Green lighting: the light source should meet the following main technical performance: (1) Gao Guangxiao, high brightness, high energy; (2) the sun light color, high color performance, light display surface color, no color cast, no color; (3) the flux stability, instability, no stroboscopic effect light pollution, but the current widely used traditional light sources are more or less with a stroboscopic effect.

LED, LCD, OLED interpretation

LED is the English abbreviation of LightEmittingDiode, after the birth in 1960s was identified as fluorescent tubes, bulbs and other lighting equipment terminator.

Following the incandescent lamp, fluorescent lamp and high intensity gas discharge lamp, LED light source is the fourth revolution in lighting technology.

LCD is a liquid crystal display (LiquidCrystalDisplay) in English, which itself can not emit light, the need to display the backlight image. LED replaces the traditional backlight source of cold cathode, which solves the defects of the traditional backlight lamp life, brightness, contrast, energy saving and so on, and prolongs the service life of LCD.

OLED is English organic light emitting display OrganicLightEmittingDisplay, OLED is different from the traditional LCD display mode, without backlight, by coating organic material is very thin, when a current is passed, these organic materials will be self luminous, known as the "dream display".
