The LED backlight is light and power-saving, and the LED backlight of the high-end products can be extended by one and a half hours. The thickness of the LED laser light guide can also be appropriately reduced, so that the weight of the whole computer is reduced. The led application backlight replaces the traditional CCFL as a light source.
But led application also has certain shortcomings, the first is the price factor, the cost is too high is the biggest obstacle of the LED backlight module, compared with the CCFL there is still a certain price gap, and the high power LED light particles heat dissipation problem, in the large size The application of TV light guides also requires the addition of a heat sink substrate, which is another additional expense.
The current investment in the led factory is not for the production capacity but the core technology for the future development of LED. In the packaging technology, the package form, the wavelength of the light and other factors will affect the backlight module. The panel manufacturer and the backlight module factory need to cooperate with the LED manufacturers with close relationship to provide special specifications for various experiments and reliability tests.
Although there is a short-term downturn in the led industry, there are still certain market opportunities at home and abroad. It depends on how the company develops its advantages to win business opportunities. In the current LED industry, product quality is a large part of the important factors, especially for export companies, LED lighting has not achieved the best results is difficult to accept.
According to the actual situation, led is mainly used in small and medium size below ten inches, and the terminal application products of LED backlight modules still need to wait for further adjustment, so as to better expand the market.
