A projection application method

Abstract

The invention relates to a projection application method applied to new media. The method comprises the following steps: taking a plane as an advertising medium, projecting a pattern plate to the surface of the plane from different angles and different directions by one projection lamp or a multi-projection-lamp combination through a fixed light source to form a new one-color, multi-color or full-color text, mark or image, generate a static, dynamic, two-dimensional or three-dimensional image combination, and display a complete multi-color multi-graph artistic vision image, wherein the pattern plate is formed by removing filter membranes unneeded by the one-color image on filter membrane substrates by laser or reducing the thickness of the filter membranes at different parts of the one-color image according to image information. Compared with the prior art, the projection application method has the advantages that the saturability and the texture of the image are improved, the space is effectively utilized, and the advertising cost is reduced.

Description

technical field [0001] The invention relates to a projection application method, in particular to a projection application method applied to new media. Background technique [0002] Existing advertising media include newspapers, radio stations, television stations, street signs, banners, car bodies, etc. Using radio stations, TV stations, newspapers, etc. to advertise requires the audience of the radio station and TV station to be watching, and television sets and radios are indispensable. Readers of a newspaper must subscribe to the newspaper in order to see the advertisement. Street signs and banners occupy three-dimensional space. Radio stations, TV stations, street signs, and banners all need to be specially set up, which increases a lot of costs. [0003] In large-scale activities, projection devices are also used to project advertisements, but usually a special projection receiving device is required to display images, and most of the existing projectors use the pri...

Problems solved by technology

However, increasing the color wheel will increase the size, weight and noise of the projection equipment, so this problem becomes a burden for the miniaturization and weight reduction of the projection equipment

[0007] Moreover, on a circular color wheel, it takes a lot of money to evenly coat the color, and the reject rate is high

[0008] In addition, the color wheel is a rotating part, which is less reliable than the fixed part and has a high wear rate, so it is more prone to failure

[0009] Moreover, the filters used in the color wheel are usually made by methods such as dyeing, pigment dispersion, printing, electroplating, and inkjet methods, which cannot meet the requirements of simple process, high precision, and low cost.
