Embodiment Construction

[0023] In order to enable those skilled in the art to fully understand the purpose, features and effects of the present invention, the present invention will be described in detail through the following specific embodiments together with the accompanying drawings.

[0024] see Figure 4 . The projection screen of the present invention is a soft curtain in the reflective screen used in the front projection system, and the structure of the screen is divided into three parts: the screen surface, the screen base, and the screen bottom. The screen base is a multi-layer structure, and the screen base layer Adhesive with sticky material. In actual production, general viscous materials can achieve the purpose. Both the curtain surface and the curtain bottom are attached to the curtain base, and the curtain base plays a supporting role. The curtain surface diffuses light and is attached to the curtain base. According to the reflection effect of the curtain surface and the different...

Abstract

The invention discloses a translucent screen, wherein, a screen base of the screen takes the structure of a plurality of layers or two layers and the layers of the screen base adhere to each other by adhesive materials. Because the concave and the convex formed by curliness of the screen for a long term can be stretched to be straight under the action of gravity after the screen is hung and unfolded and the local deformation of any screen base layer can be constrained by other layers, the breadth for fluctuation of the screen can be greatly reduced and then V-shaped waves are difficult to occur in the screen of the technical proposal, thereby the problem of smoothness of the translucent screen is well solved.

Description

technical field [0001] The invention relates to a projection equipment, in particular to a projection screen. Background technique [0002] According to the projection method, the projection system can be divided into reflective projection system (also known as front projection system, front projection system, referred to as front projection system) and transmissive projection system (also known as rear projection system, rear projection system, referred to as rear projection system) . The front projection system enables the light to be projected onto the screen surface and then imaged after reflection, and the projection light source and the audience are on the same side. Its screen is opaque and has a strong ability to reflect light. The rear projection system makes the light penetrate the screen and form an image. The screen has a high light transmittance, and the projection light source and the audience are separated on both sides of the screen. [0003] The reflectiv...
