Description

Digital economy is with holographic projection screen

Technical Field

The utility model relates to a holographic projection screen technical field specifically is a digital economy uses holographic projection screen.

Background

Digital economy refers to an economic system in which digital technology is widely used and thus brings about fundamental changes in the overall economic environment and economic activity. Digital economy is also a completely new system of socio-politics and economy where both information and business are digitized. Transactions between businesses, consumers, and governments over networks are growing rapidly. Digital economy has dominated the search for goods and services that rely on digital technology for production, distribution, and sale. The business model of the digital economy works well in itself because it creates a win-win environment for both the business and the consumer.

Holographic projection technology (front-projected holographic display), also known as virtual imaging technology, is a technology that uses the principles of interference and diffraction to record and reproduce a true three-dimensional image of an object. The holographic projection technology can not only generate a stereoscopic aerial illusion, but also enable the illusion to interact with performers to complete performance together, and generate shocking performance effects. The method has the advantages of wide application range, product exhibition, automobile clothing release, stage programs, interaction, bar entertainment, place interactive projection and the like.

The current digital economic holographic projection screen has poor imaging effect and needs to be improved.
