Japan factory Toshiba Matsushita display ultra long life LED backlight source lamp

Recently, Toshiba Matsushita Display Technology Co., Ltd. issued a long life LED backlight source lamp, mainly used for measuring instruments and medical devices using high-definition TFT LCD module. The new product support screen size is divided into 5.7, 6.5, 8.4 and 10.4 inches of the 4 types, a total of 5 models, and are available in the distribution of film resistance touch screen.

It is reported that 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 understood that the series to 6.5 inches of products as the beginning, in May 2008 began to gradually put into mass production in September 2008 last year, the production of the last 10.4 inches of products.
