Description
技术领域
本发明涉及一种投影幕组合涂料及投影幕的制备方法,属于显示屏幕制造技术领域。
背景技术
随着激光投影技术的不断发展,激光电视凭借其体积小、投影面积大、成本低等优势,得到消费者的广泛关注和认可,市场逐年扩大。虽然目前激光电视的光通量已经可以达到很高的水平,但在环境光的影响下,投影画面对比度不尽如人意。目前市场上已经出现了多种具有抗光效果的屏幕,其中黑栅型投影幕因抗光效果好,相对成本低等优势,受到了普遍关注和使用。
中国专利文献CN107297928中公开了一种光学布及涂布装置和涂布方法,其首先通过压铸或者UV固化(紫外固化)转印技术在亚克力的表面精确制备出具有棱镜结构的无色透明微棱镜光栅,然后在棱镜结构的一个斜面喷涂反光涂料,同时尽量避免棱镜结构的另一个斜面被涂料溅射;在反光涂料干燥完成后,再在另一斜面喷涂黑色吸光涂料,且需防止黑色吸光涂料溅射到反光涂料上。因为棱镜结构比较微小,人工很难完成上述工艺的喷涂操作,需要使用极其精密的机械才可以实现黑栅型投影幕的制备,其生产成本高,生产效率低。
中国专利文献CN2718623Y中公开了一种黑栅精显投影屏幕,其棱镜结构吸光面由渡染方法得到,而渡染的方式工艺复杂且成本较高。

下面具体说明本发明抗光幕的制备方法
图1为本发明投影幕制备方法的工艺流程图。如图1所示,本发明还提供一种上述投影幕的制备方法,所述制备方法包含如下步骤:
S1:制备具有多个棱镜微结构的投影幕基板10,每个所述棱镜微结构均具有相交的第一平面11和第二平面12;
S2:将吸光涂料和反光涂料中的一种涂料涂布在投影幕基板具有棱镜微结构的一侧,光固化位于第一平面11上的涂料,固化完成后,采用清洗溶剂洗除位于第二平面12上的涂料;
S3:将吸光涂料和反光涂料中的另一种涂料涂布在投影幕基板具有棱镜微结构的一侧,光固化位于第二平面12上的涂料,固化完成后,采用清洗溶剂洗除位于第一平面11上的涂料。
在S1中,具体地,多个所述第一平面11相互平行,多个所述第二平面12相互平行,所述第一平面11和所述第二平面12交替设置投影幕基板的一侧,共同形成投影幕基板一侧的外表面,本发明并不限制第一平面11、第二平面12以及投影幕基板10之间的夹角,本领域技术人员可以根据实际需要进行调整。具有多个棱镜微结构的投影幕基板可采用现有技术中的多种方式制得,本发明不再赘述。
将涂料涂布到投影幕基板上的方式包括但不限于喷涂、辊涂、刮涂、丝网印刷,优选喷涂和丝网印刷,进一步优选为喷涂。
在S2和S3中,光固化的光源可以为紫外光,也可以为可见光,其与吸光涂料和反光涂料中光引发剂的种类相关。本发明并不限定光固化的工艺参数,本领域技术人员可以根据吸光涂料和反光涂料的种类选择合适的光固化工艺。
清洗未固化的涂料时,可以采用溶剂进行清洗,优选选用吸光涂料或反光涂料中的溶剂。
下面结合具体实施例对本发明投影幕组合涂料的涂覆方法作进一步地介绍。
首先制备具有多个棱镜微结构的投影幕基板,将吸光涂料喷涂在投影幕基板具有棱镜微结构的一侧,光固化位于第一平面上的吸光涂料,固化完成后,清洗位于第二平面上的吸光涂料,从而在投影幕基板上形成吸光层;将反光涂料喷涂在投影幕基板具有棱镜微结构的一侧,光固化位于第二平面上的反光涂料,固化完成后,清洗位于第一平面上的反光涂料,从而在投影幕基板上形成反光层。
综上所述,本发明利用光固化技术对棱镜微结构的不同侧面进行分次涂布,并提供了一种适用于分次涂布的投影幕组合涂料,采用该方法制备的投影幕无需渡染工艺,也不需要复杂的平面辊装置,便可制得具有良好的抗光效果的光学屏幕,从而实现激光电视投影画面的高亮度和高对比度,与现有技术相比,具有节能环保、工艺简便以及成本低廉的优点。
