Zhao Wei of director of research center of engineering of indication technology of Shaanxi province flat shows in 2007 China flat industrial technology peak did a problem be on the meeting ” new progress of PLED indication technology and industry are looked into ” report. Zhao Wei says, PLED/OLED is the skill that material of organic semiconductor glow allots light in voltaic drive and implementation demonstrates, according to use organic data different cent is PLED and OLED. The technology of PLED/OLED monitor goes easily simplier than LCD. TFT-LCD craft makes Cheng want to experience many 200 working procedure, OLED reduces many 80, and the methodological scroll that PLED shows to screen can use ink jet to print pressworks, the manufacturing technology that compares OLED is more simple, produce cost consequently efficiency of lower, production is taller, especially PLED is making big screen advantage of high-definition TV respect is clear, flat be consideringed as indicates technical future. Of course, PLED indication technology also faces many difficult problem in the process that realizing industrialization: It is life problem, the integrated glow life of PLED is close 10 thousand hours, mix under CRT far 25 thousand hours of above of LCD; 2 it is technology issue, below current craft condition, the organic film that PLED shows parts of an apparatus is medium is made use multilayer structure, the between class of organic film layer each other dissolve in the process that make film and material of red green blue glow need to used the technical difficult problem such as different cathode material to increase PLED to produce the complex rate of craft; 3 it is cost issue, because craft is insufficient mature, the fine in producing a course tastes rate on the low side, industrialization of unfulfilment of product of together with PLED, the raw material, standardization rate that produces equipment is low, the price is high, product cost on the high side. He says, the occurrence of the problem means the presence of the opportunity, be aimed at afore-mentioned difficult problem, the researcher inside PLED course of study is exploring the way that settle ceaselessly. Professor Cao Yong and Professor A.J.Heeger research and development gave Polymer-LEC technology 1995, the application of this technology makes parts of an apparatus has monolayer organic film structure, driving voltage is low, glow efficiency is tall, in the meantime, parts of an apparatus asks to organic film ply and uniformity also the PLED/OLED of unlike tradition is so strict. Be short of regret exclusively is LEC technology makes the response of parts of an apparatus rate is slower. Shaanxi saves flat to show technical engineering research center is over the foundation of LEC technology, the advantage of integrated PLED and LEC technology, through using the means with inorganic impure salt, in hold LEC technology dominant position while, the response that raised parts of an apparatus speed. Zhao Wei thinks, the effort that expands PLED industry of China to rely on enterprise and place of scientific research courtyard only is insufficient, still need a government relevant section takes up a political career the supportive strength that each respect such as plan, capital, technology, talent enhances pair of industries to develop, resource of aggrandizement basic research, occupation standard, industry is integrated, forming domestic area to develop characteristic and international market to extend etc the respect is timely provide strategic guidance, support core technology research and development, support research and development of technology of industrial catenary key, especially the research and development of circuit of organic glow material, drive. The industrialization of PLED should from which product of small size face plate begins, because in the technical difficult problem of small size product is solved relatively easily. As the progressively development that research and development works, with monochromatic product of PLED of small face plate serves as cut a point from it is difficult to arrive easily, make workmanship moves toward maturity, it is the only way that realizes PLED industrialization.

Yong Jun of stone of assistant of president of thunder person illume discloses 19 days to LED Flashlights author, plan to offer 200 million yuan of market to award letter forehead to spend to channel business, help up in order to help overshoot economic crisis. But the analysis inside course of study, this action of thunder person illume, also have the idea that uses economic winter to quicken industry conformity. 200 million yuan, this number is equal to the sale outstanding achievement that dimensions lighting company waits for 1 year in home almost. “Before the power that big project sheet leans him channel is finished very hard independently, for example this kind of ten million estimates place of Beijing Olympic Games the project of class. Had big after the forehead that give a letter is spent, channel business can seize more market opportunity, develop quickly. ” Wu Changjiang of president of thunder person illume says, “We use agency of 200 million yuan of allowance this, should assist them to do namely do greatly strong, rangleishi is done weller in the market competition of next year. ” the target that Lei Shi gives a letter 200 million yuan this covers brand shop of many 2200 center of 36 operation of countrywide, brand and more than 1500 agency, the form includes cash and goods. Go up month, thunder person illume obtains Gao Cheng 37 million dollar is noted endowment, gao Chengcheng is the 3rd large stockholder of company. But Shi Yong army says to be below the condition that at present economic environment uncertainty adds, the profit that Lei Shineng takes out annual fills continuously channel business, still be not simple. Shi Yong army says, guangdong is in book lighting company has many 8000, add factory of small mill, mountain fastness to wait for more than 10 thousand. But because enterprise great majority devotes oneself to OEM and low end the production of the product, enter since 2008, suffer a RMB to appreciate, raw material rises in price and the influence of global economy crisis, a lot of enterprises already stop production closes. “Data shows, only Guangdong has 339 illumination first half of the year the enterprise closes down or close a business. ” although global economy puts delay, but Shi Yong army says illume course of study should be met have new development opportunity. Above all, urban construction and infrastructure and safeguard sex housing build brought opportunity. Next, strengthen lighting division to fulgurite manages and reduced urban illume to offer new opportunity for the industry with report. Occupy the data that Shi Yong army provides, outstanding achievement grew thunder person illume compared to the same period first half of the year 2008 76% , overseas sales volume grows 300% compared to the same period, yuan Chao industry is average level.

This is a heartrending times, also be a period that makes a person excited. Face market depression and dilemma of broad medium and small businesses, adjusting control of monetary policy of governmental second half of the year will ” have retain pressure ” , cooperate transition of medium and small businesses with policy of active wealth tax, blow warm wind for the market ceaselessly; Enter August, illume industry enters traditional Jin Jiuyin 10 busy season, in all previous classics successive after the sale of much month is off-season, the market gradually get warm again after a cold spell, haze drops off gradually, around Gu Zhenguo of · of the 7th China border lamp LED Strip Lights the role of exposition one year big fight also fadein war. Because market whole is fatigued and weak this year, a few be in go bankrupt and break down the enterprise of the brim, oneself only a bit energy rises centrally, send look at the risk one’s life in a few months finally one wrestle.

Drive the green train that takes energy-saving environmental protection, LED crosses illume industry to give off light to the world, the there’s no one who doesn’t or isn’t of development latent capacity that LED manufacturer applies to illume expresses great expectations, expect to drive LED to march toward the dream of -727379968 industries. However, although world each country makes the illume policy with energy-saving environmental protection in succession, predicting 2010~2012 year will ban use or discard changes incandescent lamp, but incandescent lamp takes the history, may not can make sure LED replaces immediately, before LED illume times comes, traditional light source still has many respected opponent, indoor illuminative brunt still difficult between one evening dynastic changes. LED makes Cheng make one’s fortune from semiconductor, be known as is revolution of industry of 21 centuries light, but in fact, the illumination that has in a large number of heroes changes times, be not every kinds of illuminant applicable LED is replaced. Progress of LED glow efficiency is rapid in recent years, but cost is general and at present exorbitant, bring about LED illume product to still cannot walk along illume of general family expenses, industry thinks, LED will be preferential cut not high to price susceptibility quotient to use illume, and its environmental protection does not have mercuric, life the character with point to a design long, easy solely, provide labor force to wait for the appearance of a dark horse of hair quite. But even if commercial illume domain, whether does the advantage of LED have enough driving force, conquer conventional lighting uses the market? Be afraid still have doubt, LED industry always likes to emphasize LED environmental protection saving electric advantage, but the fluorescent tube with frivolous and at present short run, still be mainstream of commercial office illuminative. Especially T5 is efficient the glow efficiency that exceeds thin solar tube is tall, sex performing color amounts to Ra85, jiashangguang outputs stability, light declines to still maintain in smooth output of 10 thousand hours in 91% , conversely, the defect that light declines to contend hard for LED; In addition, t5 tube diameter decreases, decrease by existing T9(29mm) to T5(16mm) , also can achieve the result that reduces environmental pollution, accordingly, GE of illume big plant thinks, the T5 fluorescent lamp of tall colour rendering is in future still can be indoor illuminative brunt inside 10 years, LED still has a paragraph of pursuant space. Riverside of flying benefit of another illume big plant (Philips) also thinks, LED illume market just just started, but province bulb is the person be benefited directly below energy-saving trend however, flying benefit riverside is forecasted, the yield that according to saves bulb at present can, the whole world will be in 2~3 is achieved inside year supply saturation, if did not last,enlarge is produced, produce after 4 years can will can’t supply market need. As to LED manufacturer appetent the accent lighting domain that razzia, also will surely not receive the market of traditional and haloid lamp smoothly, for example the ceramics that big plant of traditional lamps and lanterns makes with design of data of pottery and porcelain answer metallic lamp, illuminant colour rendering is Ra80~90, colour temperature stability beautiful, the pottery and porcelain of small wattage answer 50% what metallic light power consumption is haloid lamp, mean life is 4 times, in tie-in high-powered electron stable implement hind, can produce lighting quality not only, also but give attention to two or morethings is energy-saving, can saying is the semifinished product between new light source of traditional and haloid lamp and LED. GE was aimed at the whole world a few days ago furniture of the biggest chain sells undertake an analysis, with 1, 500 20 made of baked clay pottery and porcelain answer metallic lamp is replaced 2, 700 50 haloid bulb, horary will can save 118KW bulb to consume electric power, add air conditioning to consume electric power, annual a shop can save charge of electricity to amount to 600 thousand yuan about about, can reduce discharge capacity of 250 tons of carbon dioxide every year, in order to reduce greenhouse effect. Will look with this, who says green appeals to energy-savingly beg can you outshine the rest by LED only? But LED illume is not devoid opportunity, the norms of source of traditional after all light, market already country is touched calm, but LED illume still muddy Dun not bright, it is a challenge also be the opportunity that turn over, in commercial illume domain, LED is using the character of its colour diversity and directivity illuminant, reveal in commodity, adornment illume, outside wall billboard illume shine LED Lights jump the confine of traditional lamps and lanterns, make free with oneself the short ability of long, filling oneself is instantly the course of action of the soliddest Wu.

Be in an emergency in DRAM industry capital, cut capital expenditure leaves next year LED Light Bulbs face plate industry, big plant of DRAM and face plate is evaluated defer LED upper reaches invests a plan related denotative factory, LED facility plant discloses, after the manufacturer begins to cancel order to perhaps be delayed. The enlarge of the person that this depression already threatened business of shutout of photograph of block face plate and industry of LED of our country mainland produces plan, to benign development will be the LED industry of supply exceeds demand at present.
