CLK clock signal: the shift pulse provided to the shift register, each pulse will cause the data to be shifted in or out of one bit. The data on the data port must be coordinated w

In the bandgap reference module, because the operational amplifier is not completely symmetrical in actual conditions, there are offset voltages and low-frequency noise; at the sam

Aiming at the problem of LED failure. First of all, starting from the application design, it is necessary to select an appropriate circuit to reduce the threat of static electricit

One, the basic idea 1. Use the least LED to develop a new type of stereo display screen, which can enjoy the displayed content from all directions, and the power consump

Presumably everyone knows that the LED display PCB should use conformal paint. As for why this is, many people don't know. Below Fly LED LTD takes you to understand the mystery.

In the full-color LED display engineering application, there are single display projects, but more are multiple display projects. For a single display screen, the control software

1. Keep the LED pixels driven by constant current under certain conditions. The voltage change of the LED group caused by the load change of the display screen will affect the pixe
