Description

Composite Reflective Projection Screen (2)

This creation is a composite reflective projection screen, especially a composite reflective projection screen that can reflect light evenly.

With the advancement of technology, people can not only watch TV programs, movies or materials through monitors, but also use a projector to project images onto a blank wall. The projector emits light through a light source installed inside. Projecting to the forward projection area, when the projection area of the projector is facing the wall, the image can be projected onto the wall for the viewer to view the image on the wall.

Among them, many people will set a high-reflection projection screen in the projection area of the projector. The effect of reflecting light from the high-reflection projection screen is better than that of ordinary walls, and it can improve the brightness of the image. When the projection screen is presented, the viewer can watch a relatively clear image, but when the light from the surrounding environment shines on the high-reflection projection screen, it will affect the image presented on the high-reflection projection screen, resulting in the clarity of the image and the high-reflection projection screen. The contrast ratio is reduced, so the projector needs to emit bright light to project the image, in order to avoid the image on the highly reflective projection screen from being disturbed by the light in the environment.

However, as shown in FIG. 11 , since the light emitted by the projector 90 is concentrated and projected at the center of the high-reflection projection screen 80, and the light reflected by the high-reflection projection screen 80 is not uniform, when the brightness of the light is higher than When it is strong, a bright area 81 will be formed in the central part of the high-reflection projection screen 80, which will affect the viewing effect, and cause the parts on both sides of the high-reflection projection screen 80 to have low brightness and blurred images. Therefore, It is also difficult for viewers located on both sides of the high-reflection projection screen 80 to clearly see the images on the high-reflection projection screen 80 , so that the high-reflection projection screen 80 can provide viewers with a narrow viewing angle.

In addition, as shown in FIG. 12 , since the high-reflection projection screen 80 is perpendicular to the ground when it is installed, and its incident angle to light is approximately equal to the reflection angle, when the projector 90 is placed on a table or on the ground, it will automatically The high-reflection projection screen 80 projects light below the front side, and when the light is reflected from the high-reflection projection screen 80, some of the light will be reflected upward, and a bright band 91 will be formed on the ceiling, so that the projection light cannot be effectively used, and The brightness of the high-reflection projection screen 80 is affected, and therefore, the high-reflection projection screen still has room for improvement.

The main purpose of this creation is to provide a composite reflective projection screen, hoping to improve the uniformity of the light reflected by the current high-reflection projection screen, resulting in a narrow viewing angle, and when the projector is from the high When light is projected on the lower side of the front side of the reflection projection screen, the projection light cannot be effectively utilized, which affects the viewing effect of the high reflection projection screen.
