The main difference between constant current and constant voltage led display

What is the main difference between constant current and constant voltage of led display? The main difference between constant current and constant voltage of led display:



The output current of the constant current drive is constant, but the output DC voltage will change within a certain range with the load resistance value. The smaller the resistance value is, the lower the output voltage is, and the larger the resistance is, The output voltage is also higher.



The constant voltage drive is that its output voltage is fixed, but its output current will change with the increase or decrease of the load.



Generally speaking, products driven by constant current will be better and more expensive at the same time. Because of the constant current drive product, it has more circuits and chips, so that the current can be kept constant, which increases the service life and stability of the LED display.
