According to statistics, the average lighting equipment used in a car needs to use about 300 LEDs. Chongqing is the largest city for the production of Chinese cars and motorcycles. In 2011, the annual output of Chongqing cars will reach 2.6 million vehicles. It accounts for 14-15% of China's mainland. The annual output of Chongqing's motorcycle companies including foreign investment factories is nearly 10 million. If you multiply the average LED lighting consumption of each car, the future demand for LED lighting in Chongqing is amazing. .
The demand for LEDs with large backlights and illumination is bound to make the "LED" industry the next hot industry in Chongqing. Chongqing has attracted the attention of LED manufacturers.
China Silian Group spent RMB 2.1 billion to acquire Honeywell's sapphire business in Canada and to build China's largest sapphire substrate manufacturing base and an important production base for new light sources in Chongqing.
At present, in addition to Silian Optoelectronics, there are no heavyweight enterprises in the country from upstream chips, midstream packaging, and downstream lighting systems.
Tuoba expects that the investment action of Silian Group will attract upstream and downstream manufacturers such as sapphire substrates, chip packaging, integrated applications and related technologies to gather in Chongqing, and a new LED industry cluster is taking shape. 
Demand for backlight and lighting will be a hot spot for LED industry investment
At present, the world's three major notebook brands HP, Acer, Asus, and six major notebook manufacturers Foxconn, Inventec, Quanta, Wistron, Compal, and Heshuo have successively invested in Chongqing, which will drive the region. Notebook computer LED backlighting needs.
