Outdoor full-color LED electronic high-definition display large screen so-called constant current refers to what?

If you want to buy an outdoor full-color display, what others tell you to buy is the constant-current display of the full-color LED electronic high-definition display, but you do not know what the constant current refers to. Then you buy outdoor color full-color LED electronic high-definition display large-screen display is really a constant current? Here is a small series for everyone to analyze what is the constant current?

We know that the color of the outdoor full-color LED electronic high-definition display large-screen display can be changed to colorful, are made of RGB (red, green, blue) mixed three primary colors.

Outdoor full-color full-color LED electronic high-definition display large-screen display What is the so-called constant current refers to?

The lamp current is mainly controlled by the driver IC. The constant current driver IC can achieve a constant current output and control the brightness of the lamp to protect the lamp and achieve a better display effect. The red, green, and blue colors of the lamp are three colors. The die current is controlled by three identical driver ICs. The difference is that the red die requires less drive voltage than the green and blue die.

Due to the large power of the outdoor color full-color LED electronic high-definition display large-screen display single module, in order to ensure a longer life of the red die, it is necessary to increase the elimination of the output of the driver IC controlling the red die, thereby achieving the following two points: :

1. Really realize the constant of the current reached by the red driver chip to ensure the lamp life and make the display more uniform;

2. Effectively share the power of the constant current driver IC and reduce the temperature of the driver IC, thereby reducing the defective rate of the driver IC.

However, there are many outdoor color full-color LED electronic high-definition display large-screen displays on the market and do not add exclusion for the red drive IC output, which is undoubtedly a kind of jerry-building behavior. Because this product without exclusion will cause the lamp and driver IC to shorten its service life and affect the uniformity of the product display effect, it can not be called a real sense of constant current full-color LED electronic high-definition display large-screen display Instead, "high current" full-color LED electronic high-definition display large-screen display. Therefore, please broaden the eyes of our customers, choose to add exclusion of outdoor color full-color LED electronic high-definition display large-screen display.
