Embodiment Construction

[0032] Below in conjunction with accompanying drawing, this technical scheme will be further described:

[0033] Such as figure 1 As shown, a high-definition screen includes a flexible film 1, a metal film 2, a scattering and diffusion composite film 3, and sound-permeable holes.

[0034] First, the flexible film 1 with a thickness of 45-55 filaments is used as a substrate and placed on the bottom layer. The flexible film 1 is generally a tough polymer sheet with a certain thickness. Its good water impermeability allows the flexible film 1 to Used as a substrate.

[0035] Furthermore, the flexible film 1 can be a flexible film 1 of various materials such as PET and PC, but PET film and PC film are the first choice, firstly because PET film has excellent physical properties, chemical properties and dimensional stability , transparency, and recyclability. Secondly, PC film also has excellent physical properties, especially excellent impact resistance, high tensile strength, be...

Abstract

The invention discloses a high-definition screen which comprises a flexible film, a metal film and a scattering diffusion composite film. The flexible film acts as the substrate to be arranged on thelowest layer. The metal film is is plated on the surface of the flexible film by a vacuum plating mode. The scattering diffusion composite film covers the metal film. The high-definition screen also comprises sound-transmitting holes, a frame and fixing holes. The sound-transmitting holes are uniformly and densely distributed on the screen and penetrate through the screen. The frame tightly stretches around the screen for the fastening effect. The frame is provided with the fixing holes for installation. The high-definition screen has the gain value and the high-definition degree that the conventional metal screen cannot reach, and the color restoring effect of the picture is good so that the problem that the conventional metal screen is liable to oxidize can be thoroughly changed, the service life of the screen can be greatly prolonged, and the high-definition screen is worth of popularization and use.

Description

technical field [0001] The invention relates to the field of projection devices and equipment, in particular to a high-definition screen with high gain, good color reproduction and strong oxidation resistance. Background technique [0002] During the projection process of the projector, the light of the projector is usually projected on the metal coating on the surface of the screen, forming diffuse reflection and then forming an image on the screen. [0003] The traditional screen adopts a spraying process, and the surface presents continuous micro-metal powder particles to achieve 3D effects and diffuse reflection functions, and has a certain viewing angle. But such a process will cause a lot of attenuation waste to the light source of the projector, and the brightness of the picture is low. The metal particles sprayed on the surface are obvious, which affects the resolution of the projected picture and cannot achieve a true high-definition picture. [0004] At the same ...
