According to data from market research firm NanoMarkets, OLED lighting market in 2013 will reach 45 billion dollar industry. The analyst said that in recent years thanks to advances in OLED performance and manufacturing, the forecast data has made tremendous leaps.
They said the price of OLED lights than ever before, not much changed, still better than the old traditional lighting to be expensive, but the cost will be the follow-up to balance, because the life and efficiency of OLED has been improved. In recent years, OLED life increased from 24Khrs to 100Khrs.
NanoMarkets report showed U.S. Department of Energy hopes the efficiency of OLED lighting in 2012 reached 150lm / W, rather than the forecast can be achieved by 2014.
OLED manufacturing process reportedly has made considerable progress. GE and the Fraunhofer Institute have begun the process to provide OLED lamp - process (R2R) manufacturing process, the ultimate goal of significantly improving the OLED production and assembly costs.
Low-cost molecular ink printing technology is expected to promote the use of large-scale OLED backlighting market access. NanoMarkets expects OLED backlighting market will reach 1.1 billion by 2015 size.
First of all, and because the current production of OLED lighting panel size is small, the researchers hope that the recent large-size OLED panels in Asia, the scale of the increase of production is expected to improve the basis for manufacturing OLED lighting systems, and in the next few years to the large size Development.
They claimed that the thin OLED flat and flexible features for high value-added lighting market opportunities, especially high-end consumer and construction markets. For example, they pointed out that the lighting design company IngoMaurer earlier this year provides a "multi-functional desk lamp" in OLED lighting, and GE researchers also aimed to light the curtains and wallpaper available lighting.
By 2015, NanoMarkets expects the construction and special industrial applications for the OLED lighting will reach 1.9 billion U.S. dollars in the market. The report also showed that the OLED solid-state lighting applications for new OLED display that provided the company created a diverse market, these companies in the OLED display market has been powerless to combat.
However, the market research firm warned that although the application of printed OLED lighting market, the device looks very easy, but specific to each case, "careful research will find the problem."
For example, OLED lighting may be in the soft light on the panel have been used, but in the end no one knows how much of this demand, and no one can prove that the price increase in the number of value added in the end.
Challenges and Solutions
Low-cost printing technology and the R2R fabrication process is seen as the potential to accelerate LED lighting applications, the focus is very exciting, however, the report also pointed out that so far, no one in a real production environment to achieve The materials technology and processes. OLED and other printed lighting technology is the biggest challenge appears normal lighting, the report questioned consumers relatively expensive OLED lights (if you can buy it) to pay higher charges for what the reason is, while the incandescent lamp and fluorescent lamp has is so cheap. The report emphasized that "on this issue has no clear answer."
Partly because, OLED display and lighting technology is at the foundation stage of development. Although the display technology has been listed for 10 years, compared to the product manufacturer generation LCD plant is much lower, while the largest size of the OLED screen is also only 11 inch (diagonal), is still the largest commercial 2 to 3 inches of the small screen.
OLED lighting is a recent topic, its brightness, efficiency and life expectancy had reached only the "good enough" stage, and OLED-based lighting products still in development stage.
The researchers also said the research for OLED lighting can draw on the basis of OLED display R & D results - on the materials, manufacturing and other aspects - and can go on forever. For example, you can learn from the challenges the next few years, OLED display PDF AMLCD and small screen size of a large television application of research results, the display panel manufacturers tend to use larger substrates, to increase the substrate can be cut each piece of the panel number.
The researchers said the production of large-size display board of the progress of manufacturing equipment for OLED lighting to provide a good opportunity, because the large area OLED lighting will cover a larger market.
The report also pointed out that not only ILED, incandescent or fluorescent light is OLED competitors, and other technology (including printing) will result in competition in some applications.
For example, in the keyboard or industrial panel backlight, the thick field to light (EL) lamp is another technique, EL do not like the brightness and efficiency of OLED as an occasion to consider very applicable. The technology has been launched in the market and has been proved that the kind of printing as OLED, flexible features and the application of variable shape is very useful.
The report also mentioned the carbon nanotube (CNT) lighting technology threats. CNT to provide more robust, easy to damage the structure. CNT lighting is also confirmed that the printing can be achieved, so the manufacturing cost can be reduced, CNT lighting can also be transparent.
