Method for using vehicle projection film

Abstract

The invention provides a method for using a vehicle projection film. The method comprises: a vehicle projection film is attached to window glass; and after a projection device projects an image to thevehicle projection film, the vehicle projection film reflects the image to the surface of the window glass to realize imaging on the window glass. The vehicle projection film uses a transparent-material-based projection film as a bottom film and a planar and a three-dimensional pattern or a planar or a three-dimensional pattern are or is arranged on the bottom film. According to the method provided by the invention, micro printing or micro modelling processing is carried out on the surface of the film, so that most of light projected by an in-vehicle or external projection device stays on thesurface of the film and the image projected by the projection device is displayed on the film; and because the film is pasted on the window, the image projected by the projection device is displayedon the window, so that the window becomes a projection curtain.

Description

technical field [0001] The invention relates to the field of automotive electron optics, in particular to a method for using a projection film for a vehicle. Background technique [0002] With the development of the automobile industry, the use of automobiles is becoming more and more popular. People pay more and more attention to the development and application of automobile peripheral products, and the demand for automobile advertisements is also increasing. At present, advertisements in the domestic market are still concentrated on PET films. Or stickers are pasted on the rear window glass of the car or on the car shell. Such advertisements cannot be updated in real time, and the materials cannot be reused. Each replacement requires a lot of manpower, material resources, and time. Car electronic screen advertisements can be replaced and reused in real time, but traditional LED screens have high power consumption, low resolution, rough imaging, and the screens are made of ...

AI Technical Summary

Problems solved by technology

[0003] Existing projection film imaging systems are generally realized by using computers, traditional projectors, and holographic projection film equipment, but are easily affected by ambient light. Therefore, projectors with higher brightness are generally required, and they are used in places with darker light. , in order to obtain a better effect

As a result, the imaging application of projection film is greatly limited

[0004] Traditional projection film has never been used on a carrier such as a car, so traditional projection film has not considered the design and use of high and low temperature, vibration, high humidity, high dust and other operating vehicle environments
