challenge of China
OLED illuminates a technique:The opportunity and challenge of China
The 16th international lighting exposition in Guangzhou opens in the Chinese importer-exporter article commodity fair exhibition building(Ba continent) on June 9-12.Take"the industry technique guides low carbon to illuminate a life" as topic,led lighting design initiate a lighting technique the innovation promote low carbon environmental protection of the third lighting industry the latest technique and result high peak forum also the same period successfully hold.This time forum cause from domestic and international lighting product technique the engineer, manufacturer represent, lamp designer etc. the profession personage take part in and inquiry into lighting the most advanced technique of profession together, its study scope covers light source, lamp and kit 3, and brought the world-wide locations lighting the industry to lately study a result.
On June 9, come from Hong Kong to immerse giving out light of meeting university material professor expert, Chen Jin Xin,12 volt led lightingto organic technique characteristics and advantage, existent problem for giving out light diode(OLED) lighting, and did overall analysis in the development of China.Chen Jin Xin is called one of"OLED Chinese people three heroses"s and get American Russia carat in 1971 state university organic chemistry Doctor of He Ma, carry on post-doctorate studies with Nobel laureate and R.B.Woodward professor’s cooperation in Harvard University later on.He has already acquired more than 35 OLEDs that American patents invent many keys currently in the optoelectronics realm material.
Chen Jin Xin thinks that the OLED lighting has already hoped to become to will illuminate main current in the future.For the sake of economical energy consume, find out 1 kind in the meantime have Gao to give out light rate and the longevity life two kinds of lighting tools of advantages to seem to be is urgent.But the fluorescent lamp tube that use widespreadly currently again because belong to line light source, can not provide big area and even lighting light source.Therefore, have OLED of light, thin, soft and transparent etc. characteristic lighting, become suitable big area lighting and own the lighting of even bright degree to lately spoil.
Greet challenge OLED advantage obviously but still need a perfect technique
OLED, namely organic the laser giving out light diode, and then being called an organic electricity show.Its principle clips between two electrodes up organic give out light a layer, be plus or minus pole the electronics meet in this organic material will give out light.Chen Jin Xin says that OLED shows a technique according to drive a way different, can is divided into to have no source to drive OLED(PM-OLED) and have a source to drive OLED(AM-OLED).Compared with the PM-OLED, the AM-OLED has more advantages:The AM-OLED adoption making has thin film transistor(TFT) carrying on the back of sketch the plank is to show a board, can acquire to largerly show capacity and more excellently show quality, longer life span,led home lighting can carry out OLED thus the television show.In the aspects of economizing on energy, the AM-OLED displayed a dissimilarity more usually of advantage, 29 inch cathode ray tube(CRT) televisions of achievement consume about 100 tiles, 40 the inch TFT-LCD LCD TV of achievement consume about 200 tiles, 50 inch PDPs of achievement consume above 500 tiles, but the AM-OLED of one set 40 inches television, achievement consume will below 100 tiles, in view of the fact self-moving physically use only achievement consume also much lower.Chen Jin Xin said that the AM-OLED display will become market main current in 2015.
But, in the service life and give out light an efficiency two greatest problem up, OLED still needs to be continued perfect.Generally raise to give out light service life to reach to for more than 10000 hourses, give out light an efficiency then have to raise to a 30 lms|w, but the OLED light hasn’t reached this standard.Secondly, OLED creates a yield still the beard notices the whole noodles bright degree even degree and plays a color(CRI) and play a color more high, the color seen by sense of vision is just more true.Only work out an above problem as soon as possible, China then can outstrip its country on the market in OLED.In addition, Chen Jin Xin thinks that the biggest problem of OLED light lies in cost to lead Gao and only has to work out a cost problem, OLED then can make widely available in the market.
Hold tight opportunity OLED the market foreground is limitless
Because the OLED light may become the new main current that will illuminate in the future, not a few manufacturers actively throw in a development.Chen Jin Xin points out that Europe and Germany, the United States and Japanese etc. nations all adopts an item method to carry on a research.The item research mainly takes high-efficiency and high life span as to develop a principal axis, like European OLED100. eu item.Remarkable BE, in order to beg OLED lighting to commercialize soon, the European OLED100. eu item even is also included in price to develop consideration in, emphasize each square OLED to illuminate selling price for 100 euros, urge OLED the lighting has a market competition price.Participate in the manufacturer of this item to include Siemens, Philip and Europe to take charge of Lang etc., don’t lack international lighting big factory among them, but these manufacturers even still include the upper stream material company and equipments company, be good enough to see OLED illuminate development the foreground is limitless.
Chen Jin Xin points out that the lighting market scale of the whole world is about USD 7,900,000,000 currently and grow up to USD 10,000,000,000 around in 2020.Shine on the words that this is calculating, whole lighting market year reunites growth rate(GAGR) on the average only 2.1% around, among them, OLED occupy 14% markets around, namely the production value of USD 1,400,000,000.In 2020, from application category to see, generally illuminate, demonstration illuminate and carry on the back light source to have around OLED illuminate of 35%, 25% and 25%, the production value is about USD 500,000,000, USD 350,000,000 and USD 350,000,000.
Under the trend that give out light a technique to continuously improve, the industry think factory thinks, OLED may get into to commercialize a yield stage this year, and OLED illuminates market scale to quickly increase in 2011.Illuminated a development blue print to see from each OLED that the manufacturer programed, the OLED lighting market might obtain breakthrough this year progress.But the international archduke department it is more likely to cross in its patent the beginning sees clues in the middle of the authorization to the aggressive layout that the new light sources, such as OLED and LED…etc. applies, led lighting residentialthis contribute to OLED and LED lighting of market application expansion.Be showed from this, OLED market foreground will limitless.China currently to the total investment of OLED industry already more than 3,000,000,000 dollars, believe 2011 will be a year that the development of China OLED gives dint.
