LCD launched with LED module, all components are lead-free environmental protection

Recently, the Taiwan area distributor Mao Lun (GFEC) agent on birch (YoHua) white LED and ipon (YoBon) Driver IC developed by LED collocation LCD backlight module, the product will use a different specification according to customer demand for the number of white LED (3020/3528/5050) for NB/PC, such as high CRI / high color saturation can also be RGB LED (3528/5050 RGB) collocation for LCD TV/PC.

According to reports, the backlight circuit adopts ipon (YoBon) Driver IC (YB1303) Low Dropout three series and the constant current source design, every output current accuracy is less than 2%, with good uniformity, LED does not need to choose VF, not with resistance. There is no inductance / capacitance component, so there is no switching noise and EMI problem, and has two sets of control signals: PWM Control and DC Control.

The lighting circuit is arranged on the LED Light Bar and is arranged in the backlight module, and the LCM (LED backlight type) power supply specification can be standardized, the customer can shorten the design and verification time, and reduce the development cost. Operating voltage range of 10V-12V, suitable for all brands of NB lithium batteries, circuit efficiency greater than 90%, low power consumption. All components are lead-free environmentally friendly products, can be widely used in LCD backlight, LED lighting.
