How many kinds of holographic projection films are there? Where are they used?

1. Window display: The monotonous glass window has since become a large-area transparent TV projection film, which will not prevent consumers from watching the exhibits and scenery in the store through the window while playing promotional advertisements and promotional information in high definition. The magical transparent display effect will greatly attract the attention of passing consumers and achieve greater publicity benefits.

2. Interactive display: The thin and transparent features make the holographic projection film not limited by the venue and design, and it is competent for the display tasks of exhibitions, event sites, performances and other venues. Without affecting the exhibits and personnel's explanation and performance, we can fully interact with the audience through images, increase the sense of space and technology at the scene, and strengthen the audience's sense of participation and intimacy.

3. Independent display: Independent display or hanging anywhere becomes a holographic image system, which not only plays a powerful role of attraction and display, but also becomes the crowning touch to enhance the design and taste of the venue because of its crystal clear vision.

4. The projection film combined with the nano-touch film realizes that ordinary advertising windows can also be clicked interactively, which increases the content and initiative of advertising windows.

Extended data

The key reason for the rapid development of holographic projection in a short time is the mass production of low-cost solid-state lasers, such as those used in DVD players and other common devices.

These lasers have also greatly promoted the development of holographic projection. These cheap and small solid-state lasers can compete with those large and expensive gas lasers originally used for holographic projection under certain conditions, so researchers, artists and even amateurs with low budgets can participate in holographic projection research.

In addition to smart phones, the three-dimensional holographic projection chip developed by the company will also enter various display devices, such as televisions, smart watches and even "holographic desktops". At that time, the era of three-dimensional holographic projection will really come.
