Advantages Of LED As Backlight
Energy saving: the photoelectric efficiency of cold cathode lamp is about 60lm/w, while the luminous efficiency of commercial LED has reached more than 100lm / W; More environmentally friendly: toxic materials will be used in CCFL manufacturing to make TVs thinner: LED backlight changes the mechanical structure design of TV backlight, which can greatly reduce the thickness of light guide plate in traditional backlight, making LED backlight TVs thinner. Mobile phone backlight usually uses 4-5 LEDs, and laptop LED backlight requires an average of 45 LEDs; An LED TV needs 500 LEDs on average. LED backlight has penetrated into small and medium-sized displays. In mobile phone applications, 100% use LED backlight; DisplaySearch estimates that the penetration rate of LED backlight in notebook computers will reach 52% in 2009, and will grow rapidly to 81% in 2010. The penetration of LED backlight in LCD TV field has just begun, but it is of great significance.
