The thickness of less than 1/3! Stanley electric ultra-thin LED backlight

Stanley electric (STANLEY ELECTRIC) Japan successfully developed a thickness of less than the original 1/3 ultra-thin LED backlight components, and display in company technology exhibition. The new product does not use the current mainstream vertical structure, but the use of a number of wedge type light guide plate into a row of "series (Tandem)" structure, thus achieving the ultra-thin design. The trial production of backlight components support 37 Inch products. As a way of LED, each color is individually encapsulated in the RGB tricolor LED mode. LED by the company's own production, belonging to the power of 100mW ordinary products.

Stanley Electric is introduced, as a series of LED back light characteristics, in addition to ultra-thin design, but also has characteristics of good mixing and heat. Compared with the improvement of the light diffusion film, optical film and reflective plate to achieve the vertical structure of the color uniformity of the series structure using the light guide plate is easier to maintain the uniformity of color "(Stanley electric). In order to keep the color uniformity in the vertical structure, the distance between the LED light source and the optical film must be prolonged. At the same time to achieve the characteristics of thin and uniform series structure has more advantages. In terms of heat dissipation, the vertical backlight must be used to heat the air between the LED and the optical film. And there is no air layer series do not do so. The series type back light element is the inner contact frame of the LED, just need to heat up from here. In terms of cost, due to the cooling system is more simple, so "can reach the same level or below the vertical backlight" (Stanley electric). Stanley electric in May this year, "SID 2004" exhibition, demonstrated the use of a series of cold cathode fluorescent lamp element samples (New backlight LCD TV will be thinner and more electricity). This series of cold cathode fluorescent lamp series in December 2005 batch production.

In addition, in the backlight and lighting technology, white organic EL uses 45 inches and supports the cold cathode tube products are paid close attention to for lighting. The trial of the company's white organic EL on the arrangement of 3 sizes of 167mm x 47mm surface light source. Development goal is luminous efficiency 90lm/W, life 10 thousand hours. At present, the luminous efficiency of 10lm/W has been realized, and the batch production in 2010 is expected. In terms of luminous efficiency, by changing the organic EL material from the current fluorescent material to phosphorescent material, it is expected to reach 50lm/W. The life of the above sample is not announced. Support 45 inch cold cathode tube arrangement of the length of the 40 long 1470mm lamp, plans to mass production in 2005.
