OLED commercially available
Von mademms, 27.06.2012, 06:27OLED commercially available since 1997has been effective development,LED Bulb Brandup to1-3inch small size monochrome and color passive driving panel has been in the mobile phone auxiliary screen and screen, a small music player and other aspects of the application, the annual output more than7000W, but we cannot expect the future passive drive OLED in the display area will be large scale development, because of its large size and high definition of the existence of technical limitations, so that applications are significantly limited.
The future mainstream should be active drive OLED, South Korea Displaybank announced the first quarter of 08 was an active matrix type OLED panel supply performance findings, supply capacity of 27200003000, increased to28 in the same period last year times, enough to see its development is rapid. Active driving OLED another significant advantage is high opening rate, while reducing power consumption to improve life.
For the active drive OLED,beauty361 dab4d55ck people often use top emission, inversion and micro cavity structure of the device and high contrast device and their combination, the current products are mostly adopts the top emission or top emission + micro cavity structure device. In 2007December listed company Sony11 "OLED" XEL-1" TV is the top emission + Color + micro cavity structure. This market also opens the OLED television era, into the organic semiconductor industry a powerful driving force for development, to step in the concept put forward20 years later to the industrialization of a solid first step.
For OLED applications in display, from a performance point of view, fluorescent organic molecular material system has sufficient to satisfy a requirement, fluorescent organic molecular material with high stability, the device structure design and related auxiliary materials matching, red, green, blue fluorescent organic molecular material device efficiency reached 12cd/A,36.3 cd/A and 11.4 cd/A,1000CD per square metre of initial brightness, life expectancy reached 150000,62000 and20000 hours, even fluorescent type white light OLED, also its efficiency reaches 16 cd/A, life for more than 70000hours.
In the future, in addition to further improve the performance of materials and devices, particularly blue-emitting material device performance,LED Lighting supplier the development of new materials system, on a display panel of local uniform and mainly solves the problem of uneven panel, panel resolution problem, panel of ultrathin films of the problem, here is the film package and low cost technology problems. In fact, with the liquid crystal display in the display area of a decision, to be solved ultimately is cost issue, at present, companies are using the3.5 generation or the generation 4.5half cut ( half ) glass substrate, to reduce the cost of organic display panel, must use the full size of the glass substrate, but also need to to further improve the production cycle, improve production. In order to expand the production scale and expanding the board size, manufacturing equipment manufacturers need to organic display industry to provide greater equipment. Also, improve the utilization rate of materials is also facing a problem of reducing cost, because the material utilization rate of less than 5% at least, to increase to more than 20% in order to meet the demand, obviously these are and liquid crystal display for the competition must be faced with the difficult challenge.
