OLED lighting: American R & D strength inside

Editor's note: OLED lighting is considered to be the next generation of lighting technology, lighting or even replaced with LED meet as equals in strength, has become the hot research in developed countries, Germany, Japan continues to accumulate strength, and as a global technology leader in science and technology - the United States is how to treat the OLED, what kind of research plans and goals, please see the article.

First, the

The United States is actively developing new lighting devices, so in the national plan has a solid state lighting (Solid State Lighting, SSL) project, its solid-state lighting is divided into two categories, one for LED technology, and the other for OLED technology. In the OLED lighting project goal to reach 75-150 lm/W, and the service life is 10000 hours, and from 2004 to 2010, the total investment of $51 million 550 thousand in research funding for research and development, from the core research direction of the project, we can find the research scope from the production of material properties to the device material and performance test of upstream. Have related project research and development, R & D layout is the comprehensive.

Two, R & D

In 2008, the United States solid state lighting a total of 51 project, a total funding of $74 million 700 thousand (Figure 1), OLED lighting has a total of 25 projects, total funding of $36 million 900 thousand, accounting for 49.4% of all projects, including the U.S. Department of energy investment of $27 million 900 thousand, and apply to participate in the planner is $9 million; a total of LED 26 projects, total funding of $37 million 800 thousand, accounting for 50.6% of all projects, including the U.S. Department of energy investment of $28 million 900 thousand, and apply to participate in the planner is $8 million 900 thousand. From the distribution of research funding for OLED lighting and LED, we can find that OLED lighting project proportion (49.4%) is equivalent to the LED project, although OLED lighting OLED lighting has not mass production, but the bright younger generation trend, so although the United States into the research on the technology of LED lighting, OLED lighting R & D also increased, the United States is more and more visible pay attention to OLED lighting.

Three, OLED lighting project

The United States in the OLED lighting project plans a total of 25, with the core technology of OLED lighting projects 15, invested a total of $20 million 300 thousand in research funding, OLED lighting product development projects 10, invested a total of $16 million 600 thousand in research funding. The study on luminescent materials have 7 R & D projects, the investment funds of $8 million 600 thousand, accounting for 28% of all OLED lighting project, the largest investment for research projects and funding the project (Figure two); Study on the transparent conductive layer also has 5 R & D projects, the investment funds of $5 million 200 thousand, accounted for OLED lighting project 20%, R & D investment projects and funding for the project second. The remaining inputs in the material surface improvement, OLED lighting device applications, low-cost packaging and OLED lighting product development projects, a total investment of $23 million 100 thousand R & D funding. From the OLED lighting project and the number of R & D expenditure distribution, visible OLED lighting is now the main difficulties for the promotion of OLED lighting luminescent material characteristics and improve the transparent conductive layer, so the United States Department of energy to invest more resources, the establishment of more research projects, in order to solve the problems encountered in OLED lighting as soon as possible.

Four, the

OLED lighting and LED belong to the same type of solid-state lighting, although LED has been successfully produced, but the potential of OLED lighting in the future lighting market can not be ignored. Put LED and OLED lighting project from the United States to observe, OLED lighting in the future is promising, and the United States Department of energy and the participating manufacturers are willing to invest more resources to accelerate the research and development of OLED lighting, believe in overweight lighting research under OLED, OLED lighting has not far in the future, belong to light and soft light OLED lighting, will appear in the lighting environment in our daily.
