The driving circuit is an important part of LED (light emitting diode) products. The choice of driving circuit technology architecture should match the specific application in lighting, backlight and display area. The light-emitting principle of LED is to add a forward voltage to its two ends, so that the minority and majority of carriers in the semiconductor compound, giving off excess energy, thus causing the emission of photons.

The other is direct constant current power supply, LED series or parallel operation. It has the advantage of low cost, but poor flexibility, but also to solve a LED failure, does not affect the operation of other LED problems. The two forms, for some time, coexisted. Multi-channel constant current output power supply, in terms of cost and performance will be better. Maybe it's going to be the mainstream.

Large size LED backlight: From 2009 to 2012, LED backlight modules began to take advantage of light efficiency and volume compared with CCFL (cold cathode fluorescent tube), and LED backlight modules were reduced by about 2/3 in three years, rapidly eliminating the cost disadvantage. As a result, LED backlights quickly replaced CCFLS in large-size areas such as laptops, monitors, and TVS. LED universal lighting: Similar to LED entry backlighting, LED lighting began to replace incandescent and fluorescent lamps (CFLS) in 2010-2012. As the global government ban on white lighting came into effect in 2013-2014, LED lighting penetration accelerated.
