The discussion on the prospects of LED backlights has become a cliché. Due to the outstanding advantages of long life, low energy consumption, small size, fast response, earthquake resistance, low temperature resistance, and low pollution, its application fields are extremely broad. According to preliminary calculations, in the future, the electricity saved by LED lighting in China each year is equivalent to the annual power generation of the Three Gorges Power Station, and it can also reduce 80 million tons of CO2, 650,000 tons of SO2 and 320,000 tons of NO2 emissions, which is called "the history of human lighting. "Revolution" is not an exaggeration.
Laut G3 Comprehensive Report: Aus Sicht der IT sind LED-Hintergrundbeleuchtungen ein wichtiges Jahr für die Entwicklung im Jahr 2010. LED-Hintergrundbeleuchtungen verlassen sich auf quecksilberfreie-grüne Umweltschutzmaßnahmen, regionale dynamische Steuerung von Hintergrundbeleuchtungen und niedrige-Kohlenstoffemissionen Energieeinsparung, ultra-dünnes, stromlinienförmiges Erscheinungsbild, hoch Die Vorteile der Farbwiedergabe und lebendigen Anzeige haben den Ersatz von CCFL durch LED stark gefördert. Verschiedene Hintergrundbeleuchtungshersteller haben eine Kooperationsbeziehung mit LED-Hintergrundbeleuchtungsherstellern aufgebaut, um gemeinsam einen Plan zur Kombination der neuesten Technologie von großen -Lichtleitplatten vorzuschlagen. Ultra-dünne, energiesparende, umweltfreundliche und-hochwertige LED-Hintergrundbeleuchtungen werden der nächste starke Trend in der Entwicklung von Hintergrundbeleuchtungen.
However, the LED backlight module is not without its shortcomings. The problem of power consumption is still an important issue that the LED backlight module must overcome. Due to the use of more LEDs, in addition to the increase in power consumption, it also causes the problem of temperature rise. Therefore, cooling systems and sensors must also be added to solve this problem. Therefore, the thickness is thicker than that of products with CCFL backlight. .
The development of semiconductor lighting is very rapid. Statistics show that since its inception in the 1960s, the cost of LEDs has dropped tenfold and the luminous efficiency has increased tenfold every ten years. And technological progress always exceeds market expectations. Especially in 2008, the Beijing Olympic Games gave LED a doping shot. The "dream scroll" at the opening ceremony was displayed on more than 4,500 square meters, which can be called the world's largest single full-color LED backlight. When the "Five Rings of Dreams" arranged by LEDs took off, Chinese people's enthusiasm for LEDs reached a new high.
