What is a stand-alone vertical LCD advertising machine

The stand-alone version of the advertising machine can be understood literally. This is a purely manual operation of the stand-alone system. It is not equipped with a network connection module, and a storage device such as a U disk will be delivered when it leaves the factory. The stand-alone version can only upload the advertising information to the machine for playback by inserting a U disk through the USB interface on the machine. If you need to update the advertisement in the later period, you also need to copy the advertisement picture or video to be released into the U disk, and put it on the advertising machine through the U disk storage device. Then use specific software to control, split-screen playback, broadcast time, etc. The stand-alone version cannot be managed and maintained in a unified manner, so it is only suitable for a small number of users with concentrated usage locations.
