There're two buttons on the side of the light box, one will control the lights to enlighten the poster and one will control the LED display screen.
Our Type A light box has a 53*8cm LED screen on the top.
We made the belts wide enough to decrease the user's burden and make the carrying easy. We also put reflective sign panels on it to make it safer in night time use.
We make the feet of the light box with high-denstiy rubber material, which will avoid the slide when the light box is standing.
The frames are all made of aluminum alloy, which will be light and easy to open up for replacing the posters inside.
