Toshiba Matsushita display technology cable company recently released a long life LED backlight source lamp, mainly used for measuring instruments and medical devices using high-definition TFT LCD module. New product support screen size is divided into 5.7, 6.5, 8.4 and 10.4 inches in 4 categories, a total of 5 models, and are available in the distribution of membrane resistance touch screen.
The company through the use of long-life LED, while the use of mobile notebook PC field LED backlight optimized thermal design, developed the average life expectancy of more than the previous long-lived CCFL (cold cathode fluorescent tube) up to 70 thousand hours of high-definition TFT LCD module. The utility model adopts the structure of a replaceable back light unit, in consideration of the long-term use and the adaptability to the harsh environment.
Compared with CCFL type, LED backlight has the advantages of light weight, low noise, low power consumption, large brightness adjustment and so on. In addition, because Mercury is not used, the environmental load in two aspects of material and energy is smaller. Coupled with no inverter, such as high voltage circuit, but also in the structure, safety, high degree of freedom to achieve the fuselage design.
It is reported that the series will be 6.5 inches of products as a starting point, from May to gradually put into mass production in 08, in September last year, put into operation the last 10.4 inches of.
