Abstract

本实用新型提供了一种新型投影屏幕,利用荧光材料被照射时能发出荧光的性质,在普通投影屏幕的表面均匀覆盖一层荧光材料的薄膜,当光线照射到投影屏幕表面时,屏幕表面的荧光材料会发出荧光,使屏幕显示更加清晰。

Description

一种新型投影屏幕
技术领域
本实用新型涉及一种投影屏幕,尤其涉及一种高清晰度的投影屏幕。
背景技术
投影仪已成为课堂教学、作品展示、休闲娱乐等不可或缺的工具,然而由于投影距离的限制或者当投影仪使用过久时,投影仪在投影屏幕上的影像的清晰度会下降。
由此可见,现有技术有待于更进一步的改进和发展。
实用新型内容
本实用新型为解决上述现有技术中的缺陷提供一种新型投影屏幕,该投影屏幕在超过普通投影距离或投影仪使用过久的情况下,仍能显示非常清晰。
为解决上述技术问题,本实用新型方案包括:
一种新型投影屏幕,在普通投影屏幕的表面均匀覆盖一层荧光材料薄膜,利用荧光材料被照射时能发出荧光的性质,使投影屏幕显示更加清晰。
附图说明
此图为本实用新型中的一个新型投影屏幕的结构简图;
具体实施方式
本实用新型提供了一种新型投影屏幕,为了使本实用新型的目的、技术方案以及优点更清楚、明确,以下将结合附图与实施例,对本实用新型进一步详细说明。
本实用新型提供的新型投影屏幕,由普通的投影屏幕改造而得,在普通投影屏幕的表面均匀覆盖一层荧光材料的薄膜,当光线照射到投影屏幕表面时,屏幕表面的荧光材料会发出荧光,使屏幕显示更加清晰。如图所示,新型投影屏幕包括幕布1、电动卷幕机2和屏幕端杆3。幕布1表面均为覆盖有荧光材料。投影屏幕启动后,电动卷幕机2匀速的将幕布1降落下来。当投影机把影响投影到屏幕上时,覆盖有均为的荧光材料的幕布1会吸收投射来的一部分光线,发出更加明亮的光线,从而增加了屏幕显示的亮度和清晰度,满足了用户对视觉效果的要求。
