led

led, the world's most high-profile new generation of light source, called as the most promising green lighting light source in 21st century because of its advantages such as high brightness, long life, non-toxic, recyclable features. as the demand became larger in global market, led industry in china is facing a huge opportunity in the future. behind the infinite prosperity, there exists huge embarrassment in the development of chinese led industry, and that is the leds made in china have poor quality and low reliability.

mtt has rich experience in the led quality evaluation, failure analysis, and other fields. we provide a series of services for our customers in the phasesof research, application,reliability tests and after-sales. our services can shorten development cycle of products, optimize the production process, promote the product upgrading, and improve the efficiency of enterprise production.
