AI Technical Summary

Problems solved by technology

At present, the traditional projection screen display image picture is relatively poor, the color is not bright enough, and the brightness and contrast of the picture are also low.
Generally speaking, the quality of the image displayed on the projection screen will deteriorate as the brightness of the environment increases. In a dark environment or in a dark room, the projection screen can provide a better image display effect; while in an outdoor or strong light environment Under lower conditions, the display image effect is poor, the image is not clear, and the color is not bright enough
In order to display clear and high-contrast images outdoors or under strong ambient light, the general method is to reduce the brightness of the ambient light, such as drawing the curtains and turning off the indoor lights, etc., but this method is not universal
At the same time, most of the traditional super-large projection screens are bulky, difficult to install, difficult to move, and require multiple screens to be spliced, which has the disadvantage of splicing lines and is expensive
Since traditional projection screens cannot adapt well to various complex environments, it is of practical significance to need a projection technology that can well adapt to various environments

Description

technical field [0001] The invention belongs to the field of projection equipment and relates to a projection paint and its preparation method and application, in particular to a high-definition projection paint and its preparation method and application. Background technique [0002] The projection screen is the carrier of the image in the projection system. A flat surface such as white cloth, wall, etc. can be used as a projection screen. The projection screen can reflect or scatter the projection light generated by the projector. When the reflected light or scattered light enters the eyes of the observer, the observer can see the image displayed on the projection screen. At present, traditional projection screens display poor images, the colors are not bright enough, and the brightness and contrast of the screen are also low. Generally speaking, the quality of the image displayed on the projection screen will deteriorate as the brightness of the environment increases. I...
