LED lighting design needs to consider the following factors oled module

LED driver circuit design parameters including input voltage range, the number of the LED driver, LED current, isolation, EMI suppression, and efficiency. Overall LED lighting design needs to consider the following factors:Lcd display modules 
Output Power: LED forward voltage range, current and LED arrangement involved
Power Supply: AC-DC power supply, DC-DC power supplies, AC power drive
Functional requirements: the requirements of the dimming, dimming mode (analog, digital, or multi-stage), lighting control
Other requirements: energy efficiency, power factor, size, cost, fault handling (protection features), to follow the standard and reliability
More considerations: mechanical connection, installation, repair / replace, life cycle, logistics, etc.

LED lighting driver
LED lighting energy saving and environmental protection trend, the outlook is more uncertain, although the backlight display technology development for many years, the program is relatively mature, but the market heat better lighting, and in many consumer electronics market (such as mobile phones backlight) the intensity of competition, cost requirements, frequent price war, profit margins are more restricted. Some people think that perhaps in 2-3 years, LED lighting technology breakthrough, the market will start a large-scale. At the same time the application of LED lighting continuously expanding, and new markets are emerging.lcd module
