Description

一种抗强光正投影涂料、正投影屏幕Anti-glare front projection paint and front projection screen 技术领域Technical field
本发明涉及一种抗强光正投影涂料、正投影屏幕。The invention relates to an anti-glare front projection paint and a front projection screen.
背景技术Background technique
随着投影技术的日益发展，投影机搭配光学膜片呈现的图像效果越来越完美，受到了越来越多追求超大画面效果的消费者的喜爱，然而要达到精美的画面呈现效果，除了需要优质的投影机之外，一块精致的光学屏幕更加必不可少。可以说在投影机技术越来越同质化的今天，投影屏幕的好坏就直接决定了投影画面的完美程度。With the increasing development of projection technology, the image effect presented by the projector with optical film is becoming more and more perfect, and it is favored by more and more consumers who are pursuing super-large image effects. In addition to a high-quality projector, an exquisite optical screen is even more essential. It can be said that in today's increasingly homogeneous projector technology, the quality of the projection screen directly determines the perfection of the projection screen.
光学投影屏幕：光学投影屏幕是由一系列微细光学结构组成的可以使投影机光强和环境光强在屏幕结构中重新分布的投影屏幕。其特点是可以有效的减弱环境光强和增强投影机投射的光强，提升画面对比度、亮度增益、色彩还原性、分辨率等，满足人们对超高画质的需求。Optical projection screen: An optical projection screen is a projection screen composed of a series of fine optical structures that can redistribute the light intensity of the projector and the ambient light in the screen structure. Its characteristic is that it can effectively reduce the ambient light intensity and enhance the light intensity projected by the projector, and improve the picture contrast, brightness gain, color reproduction, resolution, etc., to meet people's needs for ultra-high picture quality.
现有的正投影主要由白色、灰色或者黑色的布料或者塑料制成。而白色的屏幕无法在强光下保持亮度和色彩，灰色或者深色的屏幕在强光下无法保持亮度和色彩。人们在投影屏幕上使用了菲涅尔透镜可以改变投影机主光线在观看空间的合理分布，还能消除环境光的影响，提高屏幕的对比度，散射剂则提供观看视角，但是单独采用该结构的屏幕尺寸受到限制。The existing orthographic projection is mainly made of white, gray or black cloth or plastic. A white screen cannot maintain brightness and color under strong light, and a gray or dark screen cannot maintain brightness and color under strong light. People use the Fresnel lens on the projection screen to change the reasonable distribution of the main light of the projector in the viewing space, eliminate the influence of ambient light, and improve the contrast of the screen. The scattering agent provides the viewing angle, but the structure is used alone. The screen size is limited.
