Description

Projection display device and system

A display device, especially a projection display device and system

Commodity display is one of the important means of physical commodity sales. Generally, commodities are placed on display shelves for sale. For some products, when you want to show the design idea or market positioning of the product, you will use an independent display cabinet or window, which is especially common on high-priced products such as well-known brands or 3C products.

The more common display windows are mostly arranged with the background to display the design ideas of the products. For the window display method, the visual effect is single, which requires more space and requires more time for the layout. Although the display cabinet does not take up space, the visual effect is more simple. Although the relevant industry has also introduced holographic projection display cabinets, the setup cost of holographic projection is high and requires special images to be used.
