Description

一种背光模组及喷涂治具 技术领域
本发明涉及显示技术领域，尤其涉及一种背光模组及喷涂治具。
背景技术
随着中小尺寸电子产品技术的发展，窄边框背光设计成为了影响模组边框设计的重要技术。在传统的产品设计中，通常是在背光源的表面粘贴黑色双面胶以固定显示面板，由于黑色双面胶为一种有基材的胶体，需要进行机械裁切，且裁切后需要人工或机械进行贴附，导致双面胶的宽度不能做到极窄；如果太窄则无法裁切或贴附，因而影响显示产品的边框尺寸。
发明内容
鉴于现有技术存在的不足，本发明提供了一种结构简单、能够实现窄边框设计的背光模组。
为了实现上述的目的，本发明采用了如下的技术方案：
一种背光模组，包括用于产生背光源的背光组件，所述背光组件的上表面为光学膜片，所述光学膜片上表面的四周喷涂有一层遮光层。
其中，所述光学膜片上表面还包括在所述遮光层的内侧相邻设置的透明的双面粘贴层。
其中，所述双面粘贴层为OCA。
或者，所述双面粘贴层为OCR。
其中，所述遮光层为染料。
本发明还提供了一种喷涂治具，用于喷涂上述背光模组的所述遮光层，包括矩形的第一遮板和第二遮板，所述第二遮板为框体结构，且所述第一遮板位于所述第二遮板内，所述第一遮板和所述第二遮板通过连接条连接形成位于所述第一遮板和所述第二遮板之间的间隔槽，通过所述间隔槽可进行喷涂。
其中，所述连接条为多个，将所述间隔槽间隔成多个孤立的区域。
其中，所述第一遮板中部开设有镂空槽。
本发明的背光模组的光学膜片四周喷涂有遮光层，很好地解决了现有技术黑色双面胶在机械裁切时工艺复杂、不能做到窄边框显示的缺陷，同时提升了显示产品的光学品味。
附图说明
图1为本发明实施例1的背光模组的俯视图。
图2为本发明实施例1的背光模组的侧视图。
图3为本发明实施例2的背光模组的喷涂治具结构示意图。
具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
实施例1
参阅图1和图2，本发明提供了一种背光模组，包括用于产生背光源的背光组件10，背光组件10的上表面为光学膜片，光学膜片上表面的四周喷涂有一层遮光层20。
遮光层20形成于背光组件10最上面一层的光学膜片的四周边上，用于吸收背光组件10四周产生的多余光线，消除光污染的同时避免产生高亮区域。
为了将液晶面板粘贴于背光组件10上，光学膜片上表面在遮光层20的内侧相邻设置有透明的双面粘贴层30。其中，双面粘贴层30为OCA(Optically Clear Adhesive，固态透明光学胶)或OCR(Optical Clear Resin，液态透明光学胶)。考虑到双面粘贴层30的可压缩性，本实施例的双面粘贴层30的厚度略大于遮光层20，液晶面板与背光组件10粘贴后双面粘贴层30与遮光层20高度相同。可以理解的是，双面粘贴层30的厚度也可以设置为与遮光层20相同。
具体地，为了达到遮光吸光效果，遮光层20为黑色的染料或墨水等。
实施例2
如图3，为了提高遮光层20的喷涂精度和喷涂效率，本发明还提供了一种喷涂治具100，包括矩形的第一遮板101和第二遮板102，第二遮板102为框体结构，第二遮板102的外形尺寸大于背光组件10，且第一遮板101位于第二遮板102内，第一遮板101和第二遮板102通过多个连接条105连接形成位于第一遮板101和第二遮板102之间的间隔槽103，通过间隔槽103可进行喷涂。
多个连接条105间隔设置在第一遮板101和第二遮板102之间，用于对二者进行连接，将间隔槽103间隔成多个孤立的沟槽区域。
同时，为了降低喷涂治具的制造成本以及重量，第一遮板101中部开设有镂空槽104。
具体喷涂时，将喷涂治具100盖设于背光组件10的光学膜片的上表面，确定好喷涂位置后即可对准间隔槽103进行喷涂，形成遮光层20。
本发明的背光模组通过在光学膜片四周喷涂有遮光层20，很好地解决了现有技术黑色双面胶在机械裁切时工艺复杂、不能做到窄边框显示的缺陷，同时避免了光污染，提升了显示产品的光学品味。
以上所述仅是本申请的具体实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本申请的保护范围。
