湖南商场广告牌批发
I、A few days ago, I saw a billboard on the roof of a mobile building in Zhuzhou, Hunan. It was clearly an inkjet advertisement during the day, but why did it turn into an LED display at night?
This billboard is an LED billboard that flips on both sides. During the day, it has two printing surfaces. At night, the third side automatically turns out to be a full-color screen. This kind of advertising screen does not need to be equipped with a cooling air conditioner, so it is environmentally friendly and energy-saving. . The manufacturer of this screen is Hunan Xinyuan Electronic Technology Group.
