Tips about the current of LED display

LED display manufacturer introduced the screen controller with PC and HUB module and screen connected properly, you need to provide +5V power controller to make it work. Electric instant-on, bright line will appear on the screen in a few seconds or "splash screen" bright line "or" screen "are normally tested phenomena, remind the user screen is about to start work.

However, parameters, there are some differences between the devices and the LED forward voltage drop as temperatures rise, different LED differences may because the thermal conditions and an operating current If differences.

Central management software to accomplish the function of management, control of more than one screen, to edit the displayed data storage. Meanwhile, software for remote control and remote data acquisition of all terminals. LED screen Center management software and complete the information storage and management. On the same Center, information on multiple terminals and State control.

We believe life test LED, connected in series with constant-current drive and works better. Common power supply IC consisting of 78 series LED constant current drive circuit, which is characterized by low cost and simple structure, high reliability through adjust the potentiometer resistance value, convenient adjustment constant current application-wide supply voltage range.
