!A light box that does not need to be printed when changing the light box picturePreviously, in the residential building near the elevator to see security personnel in the light box inserted a U disk, and then update the light box after the change of the picture, no need to print pictures and the like. Now I need one badly, too!!! Experts in this field are requested to provide resources!
There are three common ways:1, computer connection control2, U disk control (need to be set on the computer first)3, wireless network control.
You can search on the Internet: advertisements or advertisements on color lcd.The U disk you're talking about is just a control.
This is a color LEd screen or LCD display advertising lamp bar!
