Description

一种环保型投影透射屏及其制备方法Environment-friendly projection transmission screen and preparation method thereof 技术领域Technical field
本发明涉及一种环保型投影透射屏及其制备方法，具体而言涉及一种环保领域的新材料。主要应用于广告户外、室内外装饰装修、展览展示中。The invention relates to an environment-friendly projection transmission screen and a preparation method thereof, in particular to a new material in the field of environment protection. Mainly used in outdoor advertising, indoor and outdoor decoration, exhibition and display.
背景技术Background technique
目前，投影系统广泛应用于商业演示、多媒体会议室、教室、体育场馆等场合，所采用的投影方式主要有正投和背投。相应地，投影屏幕从投影方式上也可以分为正面投影屏幕(反射式)和背面投影屏幕(透射式)。所谓正投就是投影机的安装位置与观众在投影屏幕的同侧，投影机发出的光线投射到投影屏幕，在投影屏幕上形成图像，然后光线再反射到人眼睛。类似地，所谓背投就是投影机的安装位置与观众分别位于投影屏幕的两侧，投影机发出的光线从投影屏幕的一侧直射到投影屏幕，光线透过投影屏幕进入观众眼睛。正投屏幕不受尺寸的限制，但需要控制环境光才能得到很好的观看效果，在环境光线和照明很好的环境下会造成画面对比度的严重下降。而背投屏幕画面整体感较强，画面色彩艳丽，形象逼真，且不需要控制环境光，适用于环境光线和照明很好的环境，但是背投屏幕在尺寸上不如正投，且需要足够的背部空间，以确保投影距离。并且，目前并没有能同时用于正投和背投的双面高清屏幕。At present, projection systems are widely used in commercial presentations, multimedia conference rooms, classrooms, stadiums and other occasions. The projection methods used are mainly front projection and rear projection. Correspondingly, the projection screen can also be divided into a front projection screen (reflective type) and a rear projection screen (transmissive type) from the projection mode. The so-called front projection is that the installation position of the projector and the audience are on the same side of the projection screen, the light emitted by the projector is projected onto the projection screen, an image is formed on the projection screen, and then the light is reflected to the human eye. Similarly, the so-called rear projection is that the installation position of the projector and the audience are located on both sides of the projection screen, and the light emitted by the projector is directed from the side of the projection screen to the projection screen, and the light enters the eyes of the audience through the projection screen. The front projection screen is not limited by the size, but it needs to control the ambient light to get a good viewing effect. Under the environment with good ambient light and lighting, it will cause a serious decline in the contrast of the picture. The rear projection screen has a strong overall feeling, the picture is colorful, the image is realistic, and does not need to control the ambient light. It is suitable for environments with good ambient light and lighting, but the rear projection screen is not as good in size as the front projection, and it needs sufficient Back space to ensure projection distance.
