Embodiment Construction

[0057] Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

[0058] figure 1 It is a block diagram illustrating the elements and manufacturing process of the screen according to the present invention.

[0059] Such as figure 1 As shown in, the present invention includes: selecting a non-flammable metal alloy (A1), coordination of scattering and reflection (A2), selecting the shape of the screen according to its application (A3), strengthening the hardness of the screen surface (A4) and executing the screen To zoom in (A5).

[0060] According to an embodiment of the present invention, a surface reflective screen formed of a non-combustible metal has a silver-white non-combustible metal sheet, wherein the metal sheet is made of an alloy of iron (Fe) and chromium (Cr), or iron (Fe) and It is formed by an alloy of chromium (Cr) and a small amount of nickel (Ni).

[0061] Through buffing, spraying,...

Abstract

The invention relates to a screen for displaying an image projected from a beam projector. The screen base is formed from a silver-white non-combustible metal sheet to display images projected from the light source in natural colors. A polished surface is formed on the screen substrate by polishing the screen substrate so that the surface of the screen substrate has a predetermined reflectance. The surface of the screen base is surface-hardened by pickling treatment or anodizing treatment. The surface reflection type screen formed of non-combustible metal according to the present invention has excellent surface hardness, corrosion resistance and acid resistance, thereby making the screen easy to repair and maintain. In addition, in the event of a fire, the screen does not generate toxic gas, and it is also capable of displaying high-quality images on the screen.

Description

Technical field [0001] The present invention relates to a projection screen for displaying images emitted from a light source and a manufacturing method thereof. More specifically, the present invention relates to a large-size screen that can be used in places where a large number of people move and gather, and a method of manufacturing the same. Background technique [0002] Conventional projection screens are easily melted at high temperatures because the image area of ​​the screen is made of combustible materials such as polyvinyl chloride (PVC) and plastic. In addition, conventional screens cannot be used in closed spaces used by many people, such as subways and department stores. This is due to the fact that the screen melts in a closed space in the event of a fire, thereby producing toxic gases that can kill many people. [0003] In the spherical screen using an aluminum film disclosed in Korean Patent No. 100127, the aluminum film should have ductility in order to form the...
