Qingdao LED display unit board led display, LED display module, or simply known as the cell plate is the main component unit LED display led display control card, the LED light-emitting diode and driver circuit, the driver IC and plastic packages constitute. LED display industry, LED unit board now divided into two categories. Indoor unit board industry commonly referred to as surface mount (triple paste); outdoor and semi-outdoor commonly referred to as modules. Indoor surface mount features: Wuhan led display high-definition images, rich in color and inadequate that the price is too high; outdoor and semi-outdoor module unit board characteristics: high brightness, waterproof, colorful, less than that required for installation technology guidance. LED lighting products need to choose small, small components, long life driving scheme common LED driver circuit architecture can score many categories, such as with a current-limiting resistor circuit architecture, or the use of switching power supply circuit architecture design, or use linear The LED drive current driving circuit architecture. But limiting circuit architecture is through the resistance line series resistance, LED light source device for controlling the flow of forward current amount, but there are a lot of disadvantages of this design approach has gradually switched linear constant current LED driver architecture light driven design.
