LED 27 inch LCD TV with odd push

Taiwan famous LCD panel manufacturers (Chi Chi Mei Industrial Company) a subsidiary of Qiling science and technology company, before the date of trial produced by using LED as the backlight of the 27 inch LCD TV, and held in the city of Taipei "COMPUTEX TAIPEI 2006" Exhibition on the show. A total of 30 sets of LED lights were used for each of the exhibits, each consisting of 4 LED lights, including 1 red LED lights, 2 green LED lights and 1 blue LED lights. Other parts of the LCD panel, such as backlighting, still seem to use the existing products. Prototype power consumption is 125W. According to the published product specifications, the backlight brightness of its own 4500cd/m2, brightness uniformity of 80%, color performance compared with NTSC was 100%.

Topics include cost, uniformity and manufacturing methods". Qi Ling science and technology, said it is stepping up the development of equipped with LED backlight LCD TV, and strive to put into operation in 2007. As before the project should be resolved, the company staff mentioned 3 points. Including the cost of LED, LED quality instability, and the establishment of mass production methods.

For the cost of LED, the prototype using LED lights each up to about $5, "if the purchase cost current into production, 27 inch product prices will reach $5000 to $6000, and the price of about $1000 in common LCD TV gap is too great. Need to further reduce costs". In addition, the quality of the delivered LED is not stable, in order to make the entire screen uniform luminescence must further improve the quality of LED. As for the manufacturing method, in the 3 to 10 inches of small and medium size LCD display has been established mass production technology, but there is no available to be applied to large-size LCD panel technology".

And in terms of temperature, even in the exhibition on the day, the temperature can be maintained at a stable 40 ~ 45 degrees. The extent of this impact on the LED backlight life is very small, it is estimated that not a big problem". In addition, a 17 inch LCD technology Ling also exhibited a picture brightness up to 1000cd/m2, and a 47 inch LCD at a resolution of 1920 x 1080 equipped with touch panel and watercolor drawing software system and other products.
