In addition, due to the use of mercury, in the material, energy two aspects of environmental load is small, and there is no inverter and other high voltage circuit, so you can achieve a higher degree of freedom in the structure, safety of the fuselage design. 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. The series will be 6.5 inches of products as a starting point, from May 2008 to gradually put into mass production, in September 2008 put into operation the last 10.4 inches of products. In addition, the product in May 14, 2008 to 16 in Tokyo on the International Exhibition Center held the "Eleventh embedded system development technology exhibition" on display and in May 20, 2008 to 22 in the United States of Losangeles organized by the "SID2008InternationalSympo-sium SeminarandExhibition show".
