具体实施方式
下面结合附图和实施例,对本发明的具体实施方式作进一步详细描述。以下实施例用于说明本发明,但不用来限制本发明的范围。
请参图1和图2,本发明实施例中提供的触控显示屏,包括触控模组1、显示模组2和贴合层3。触控模组1与显示模组2经贴合层3粘合在一起形成整体结构。其中,贴合层3包括微纳结构31及环绕在微纳结构31周边用于粘合触控模组1与显示模组2的粘贴部32。
在本实施例中,贴合层3设置在触控模组1的表面,微纳结构31的凸起的截面形状为两弧形边由靠触控模组1一侧朝显示模组2延伸相交形成。
在其它实施例中,贴合层3设置在显示模组2的表面,微纳结构31的凸起的截面形状为两弧形边由靠显示模组2一侧朝触控模组1延伸相交形成。
粘贴部32的材质为OCA光学胶;粘贴部32呈口字型。
贴合层3的厚度略大于微纳结构31的高度,贴合层3的厚度与粘贴部32厚度相等。具体地,贴合层的厚度为20~200μm,优选的,贴合层的厚度为50μm。
触控模组1还包括基底11、第一结构层12、绝缘支撑层13和第二结构层14。基底11的材质为透明的PET或PC或PMMA;绝缘支撑层13的材质为UV固化 胶。
第二结构层14设置在贴合层3远离显示模组2一侧的表面;绝缘支撑层13设置在第二结构层14远离贴合层3一侧的表面;第一结构层12设置在绝缘支撑层13远离第二结构层14一侧的表面;基底11设置在第一结构层14远离所述绝缘支撑层13一侧的表面。
第一结构层12包括第一光胶层121和第一导电层123,第一导电层123设置在第一光胶层121上;第二结构层14包括第二光胶层141和第二导电层143,第二导电层143设置在第二光胶层141上。
第一光胶层121上设有第一图形凹槽1213,第一导电层123嵌设在第一图形凹槽1213内;第二光胶层141设有第二图形凹槽1413,第二导电层143嵌设在第二图形凹槽1413内。
由于在第一光胶层121和第二光胶层141上均设置相应的图形凹槽,使第一导电层123与第二导电层143之间的起绝缘隔离作用的第二光胶层141较薄,会造成导电材料的贯穿渗透,从而容易引发导电层短路,使产品良品率太低,无法实际量产。因此,通过在第一光胶层121与第二光胶层141之间设置绝缘支撑层13,大幅度提高第一导电层123与第二导电层143之间的绝缘效果,有效地防止导电层的短路;同时在控制触控模组1厚度不变或更薄的前提下,可以实现将第一光胶层121和第二光胶层141适当做薄,留出厚度空间来单独设置的绝缘支撑层13进行绝缘隔离,这样可以进一步加强绝缘效果。
触控模组1还包括表层15,表层15设置于基底11远离第一结构层12的表面,其可以通过涂布或者压印等方式形成在基底的表面上。具体地,表层15为硬化层,该硬化层15可以起到保护基底表面的作用。
在其它实施例中,表层15为防眩光层,该防眩光层能够减少触控显示屏表面的眩光。当然,表层15还可以为具有其他功能性的膜层。

本发明第二实施例提供的触控显示屏制作方法与上述第一实施例的区别在于,在本实施例中,第一导电层直接制备在透明基底上。
在本实施例中,制备第一导电层的具体步骤为:采用压印的方式在透明基底上形成第一图形凹槽;在第一图形凹槽内填充导电材料,固化后形成第一导电层。
在其它实施例中,制备第一导电层的具体步骤为:在透明基底上采用印刷方式将导电材料印刷在透明基底上,固化后形成第一导电层。
第三实施例
本发明第三实施例提供的触控显示屏的制作方法与上述第一实施例的区别在于,在本实施例中,贴合层制备在显示模组表面。
在本实施例中,制备微纳结构的具体步骤为:在显示模组表面涂布一层UV固化胶;压印并固化后,形成微纳结构。
本发明有许多优点。
1、通过设置微纳结构及环绕微纳结构的粘贴部,使触控显示屏在具有全贴合效果的同时,还能够降低粘贴部使用成本和支撑触控模组或显示模组, 并且,由于粘贴部设置在微纳结构的周围,还能够减少贴合的不良率,从而降低返工的概率;同时,通过采用此种设计的贴合层将触控模组与显示模组进行粘贴,能够有效降低触控显示结构厚度。
2、通过微纳结构的凸起的截面形状为两弧形边朝显示模组或朝触控模组延伸相交,微纳结构在起到支撑缓冲显示模组或触控模组的作用同时,还在触控模组和显示模组贴合时,防止气泡产生,增强了贴合牢度和触控显示屏触控灵敏度。
3、在第一结构层与第二结构层之间设置绝缘支撑层,在加强绝缘的作用的同时,绝缘支撑层与第一结构层和第二结构层形成复合层结构,增加了导电膜耐弯折的性能,进一步提升了产品的稳定性,也扩大了产品的应用场景,适合柔性屏等多点触控的需求。
在附图中,为了清晰起见,会夸大层和区域的尺寸和相对尺寸。应当理解的是,当元件例如层、区域或基底被称作“形成在”、“设置在”或“位于”另一元件上时,该元件可以直接设置在所述另一元件上,或者也可以存在中间元件。相反,当元件被称作“直接形成在”或“直接设置在”另一元件上时,不存在中间元件。
在本文中,用于描述元件的序列形容词“第一”、“第二”等仅仅是为了区别属性类似的元件,并不意味着这样描述的元件必须依照给定的顺序,或者时间、空间、等级或其它的限制。
以上所述实施例的各技术特征可以进行任意的组合,为使描述简洁,未对上述实施例中的各个技术特征所有可能的组合都进行描述,然而,只要这些技术特征的组合不存在矛盾,都应当认为是本说明书记载的范围。
在本文中,术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含,除了包含所列的那些要素,而且还可包含没有明确列出的其他要素。
以上所述,仅为本发明的具体实施方式,但本发明的保护范围并不局限于此,任何熟悉本技术领域的技术人员在本发明揭露的技术范围内,可轻易 想到变化或替换,都应涵盖在本发明的保护范围之内。因此,本发明的保护范围应以所述权利要求的保护范围为准。
