The primary side scheme, by completely controlling the output power and current in the ac primary side, can achieve the most accurate constant current accuracy of 5%, the secondary side only needs a simple output circuit. The primary side mainly relies on the feedback of the secondary side to control the output voltage, the current control of the primary side depends on the current limiting resistance.

Leakage current LED is a unidirectional conductive light emitting body. If there is a reverse current, it is called leakage. LED with large leakage current has short life and low price. The light Angle of LEDs for different purposes is different. Special luminous Angle, higher price. If full diffuse Angle, the price is higher. The life span is different. The key to quality is life, life is determined by light decay. Small light decay, long life; Long life, high price.

Although the double primary color screen can not reach the full color display effect, it has been widely used because of its high performance and price. You can display text, pictures, animations, and video images. Full color: The luminous pixel of LED display has three colors: red, green and blue. Depending on the combination of different gray levels of the three primary colors, red, green and blue can better return the colors of nature, with rich expressive force. Theoretically speaking, its color reduction ability exceeds that of television. Will become the development direction of LED display.
