What is a projection film?
The Film Film Film Film is an updated 2011 technology on a standard type of film projector process that uses a polymer -based film that is adhered to by an acrylic or glass surface. The film has built -in microscopic materials that give it the ability to respond in a unique way to a light image screened from the video projector mounted behind it. The film shows the properties of optics such as reflection and diffusion of light, which makes the acrylic or glass surface a visual display and interactive medium. The surface can serve as a touch screen that responds to viewers' commands or a marketing system for products. One of the main advantages that such a film offers is that when the video projector is turned off, the glass or acrylic screen can be attached to the conventional window that is part of the retail device.
Rear projection film (RPF)JEK available in rolled leaves, which are approached themselves and can be easily cut at their own size and holding a glass or acrylic surface. It is designed to allow viewing of images from any angle, and can be easily removed from the surface or integrate with another built -in graphics that is already on the glass. Under the RPF itself, the type of touch screen film is often applied to provide the interactivity of the visual display. Large projection surfaces use a film for applications such as trade fair or digital brand displays in retail stores and organizations such as museums, where smaller versions are used to create interactivity in kiosks and for individual touch screens.
projection surfaces are less important in the quality of the images produced by a projection film than the video projector itself. While the film is versatile and will work with most of any video projector to create the results of the front projection or standard results from behindHill, the higher the quality of the projector, the better the image that is displayed by the film. The rear projection is often selected through the projection forward because it allows you to hide the video projector and eliminates the shadows that are formed when objects pass between a forward projector and a film.
The often decisive quality factor for the results of the image created by the projection glass surface is the amount of light or lumens that focus on the square area of the film from the video projector. 80 inches (2.03 meters) on one side screen shows a much more vivid image if the screen is located in an interior building far from outer light than the image with the same amount of lumens and size that forms the outer glass wall of the retail store. The type of illumination used by the projector also makes the difference, with standard bulbs different of the less lumens on the screen than the LED emitting diodes (LED).
The larger the surface of the projection movie is that it has to be that they have toBeing a video projector to occupy a clear picture on the film. This is known as the "throwing ratio" or "distance of throwing" for the projector and is a multiple of the screen width. Other decisive factors in the quality of the projection film image may include the sophistication of the film itself, because some materials are based on liquid crystal technology (LCD), which generates their own colors, contrast foils that depict darker images or standard white film, which mainly rely on the quality of the projector for satisfaction. Some types of projection films are also designed to simply display an opaque gray image when it turns off and becomes transparent when it is turned on as a form of a convenient personal data protection barrier in offices and houses.
