Description

一种量子点材料玻璃板及其制作方法 技术领域
本发明涉及一种显示设备技术，特别是一种量子点材料玻璃板及其制作方法。
 背景技术
量子点材料是以半导体晶体为基础的，尺寸在1~100纳米之间，每一个粒子都是单晶。量子材料的优势来源于半导体纳米晶的量子限域效应，或者量子尺寸效应。当半导体晶体小到纳米尺度（1纳米大约等于头发丝宽度的万分之一），不同的尺寸就可以发出不同颜色的光。因此在现有新型材料中，量子点材料多应用于电子领域，如照明设备、移动设备及电视设备等。
在目前常见的白光LED背光中，其发光原理为蓝光LED激发黄色荧光粉，其色域饱和值（NTSC值）约在60%~80%之间。目前已有一种蓝光LED，激发纳米级的量子点，利用量子效应，可使NTSC达到100%以上，从而提升面板的显示品质。但这种量子点材料的封装是当前研究的重要命题，传统的做法是将量子点材料封装在玻璃管内，其制程较为复杂，且玻璃管封口处的无效发光区域比较宽，占用多余空间较大，不利于窄边框设计。按照显示模组的窄边框设计理念，玻璃板周围部件（不能显示影像的边框部分）的表面积越小越好。因此，如何能在保证量子点材料封装效果的前提下，尽可能地减少无效区域（非显示区域）。
 技术问题
本发明的目的在于，解决现有技术的量子点材料玻璃板在封口处无效发光区过宽、不利于窄边框设计、制程比较复杂等技术问题。
 技术解决方案
为实现上述目的，本发明提供一种量子点材料玻璃板，包括一第一玻璃基板；一第二玻璃基板，与所述第一玻璃基板平行设置，其形状与所述第一玻璃基板相应；一胶层，设置于所述第一玻璃基板与所述第二玻璃基板之间，其边沿与所述第一玻璃基板、所述第二玻璃基板的边沿相应；其中，所述胶层包括至少一并排设置的胶框，每一胶框包括至少三个首尾依次相连的边框，每一胶框内均匀分布有量子点材料。
其中，所述第一玻璃基板、所述第二玻璃基板的形状、尺寸相同，位于同一胶层内的至少一胶框的形状、尺寸相同，所述胶框为矩形环状结构。所述边框的宽度范围为0.1mm~1mm，任意两个相邻胶框之间的距离为0.1mm~0.5mm，所述胶层边沿与所述第一玻璃基板边沿的距离范围为0.1mm~0.5mm。
为实现上述目的，本发明还提供一种量子点材料玻璃板的制作方法，包括如下步骤：获取一第一玻璃基板、一第二玻璃基板，二者平行设置；在所述第一玻璃基板朝向第二玻璃基板一侧的表面上设置一胶层，其边沿与所述第一玻璃基板的边沿相应；所述胶层包括至少一并排设置的胶框，每一胶框包括至少三个首尾依次相连的边框；在每一胶框内涂布量子点材料；将所述第二玻璃基板通过所述胶层贴合至所述第一玻璃基板；固化所述胶层，形成一复合玻璃板；沿着相邻两个胶框的交界处，将所述复合玻璃板切割成至少一量子点材料玻璃板；以及对所述量子点材料玻璃板进行磨边处理。
 有益效果
本发明的优点在于，可以有效封装纳米级的量子点，有利于提高色域，增强显示效果；同时，大幅减小量子玻璃板无效发光区域的宽度，可适于窄边框模组。本发明根据胶框的位置将整体玻璃板切割成多个量子玻璃板，可以大幅提高生产效率，降低加工成本。本发明只要对现有设备进行简单改造即可实现，灵活性高，工艺改造成本较低，适合大规模推广应用。

 本发明的最佳实施方式
以下参考说明书附图介绍本发明的一个优选实施例，证明本发明可以实施，这些实施例可以向本领域中的技术人员完整介绍本发明，使其技术内容更加清楚和便于理解。本发明可以通过许多不同形式的实施例来得以体现，本发明的保护范围并非仅限于文中提到的实施例。
在附图中，结构相同的部件以相同数字标号表示，各处结构或功能相似的组件以相似数字标号表示。附图所示的每一组件的尺寸和厚度是任意示出的，本发明并没有限定每个组件的尺寸和厚度。为了使图示更清晰，附图中有些地方适当夸大了部件的厚度。
当一个组件被描述为“安装至”或“连接至”另一组件时，二者可以理解为直接“安装”或“连接”，或者一个组件通过一中间组件间接“安装至”、或“连接至”另一个组件。
如图1、图2所示，本实施例涉及一种量子点材料玻璃板，包括一第一玻璃基板1及一第二玻璃基板2，两块玻璃基板平行设置，二者形状、尺寸相同，位置相应。
第一玻璃基板1、第二玻璃基板2的形状、尺寸相同，位于同一胶层内的多个胶框的形状、尺寸相同，本实施例优选5个，胶框4为矩形环状结构。第一玻璃基板1及一第二玻璃基板2可以选用特殊的强化玻璃，如经过化学强化处理的强化玻璃，可以提高量子板的强度。
本实施例包括一胶层3，设置于第一玻璃基板1与第二玻璃基板2之间，其边沿与第一玻璃基板1、第二玻璃基板2的边沿相应。胶层3边沿与第一玻璃基板1边沿的距离范围为0.1mm~0.5mm，本实施例优选0.3mm。
胶层3包括多个并排设置的胶框4，本实施例中优选五个，生产厂家可以根据需要调整胶框数量。本实施例中，胶框4即为用胶涂布成矩形环状的框，胶层3、胶框4采用的胶为UV光固化胶或电子束固化胶或热固化胶。每一胶框内均匀分布有量子点材料5，量子点材料包括但不限于铜铟硒材料、铜铟镓硒材料或碲化镉材料。任意两个相邻胶框4之间的距离为0.1mm~0.5mm，本实施例中优选为0.5mm。便于后续的切割操作，确保切割后量子点材料密封良好无泄漏，同时可以确保切割后无效区域较小，提高了整块玻璃基板的利用率。
每一胶框包括四个首尾依次相连的边框41，边框41的宽度范围为：0.1mm~1mm，本实施例中优选为0.5mm。相对于现有技术，边框宽度有了明显的减小，可以提高整块玻璃基板的利用率使得无效区间尽量小。
如图3所示，本实施例还提供一种量子点材料玻璃板的制作方法，包括以下步骤。
步骤S1）获取一第一玻璃基板、一第二玻璃基板，二者平行设置。第一玻璃基板1及一第二玻璃基板2可以选用特殊的强化玻璃，如经过化学强化处理的强化玻璃，可以提高量子板的强度。
步骤S2）在所述第一玻璃基板朝向第二玻璃基板一侧的表面上设置一胶层，其边沿与所述第一玻璃基板的边沿相应，也即第一玻璃基板、第二玻璃基板、胶层的边沿对齐。本实施例中，所述胶层包括四个并排设置的胶框，每一胶框为一矩形环状框，包括四个首尾依次相连的边框。胶层、胶框采用的胶为UV光固化胶或电子束固化胶或热固化胶。胶层3边沿与第一玻璃基板1边沿的距离范围为0.1mm~0.5mm，本实施例优选0.3mm。
步骤S3）在每一胶框内涂布量子点材料。量子点材料，又称为纳米晶，是一种由II-VI族或III-V族元素组成的纳米颗粒，量子点粒径一般介于1～10nm之间，量子点具有宽的激发谱和窄的发射谱，量子点发射光谱可以通过改变量子点的尺寸大小来控制，通过改变量子点尺寸和它的化学组成可以使其发射光谱覆盖整个可见光区。量子点材料包括但不限于铜铟硒材料、铜铟镓硒材料或碲化镉材料。
步骤S4）将所述第二玻璃基板通过所述胶层贴合至所述第一玻璃基板，两层玻璃基板通过胶层紧密贴合。
步骤S5）固化所述胶层，形成一复合玻璃板。固化过程是根据胶层所用的胶的类型来选择固化方式。若胶层为UV光固化胶，此处采用UV固化方式；若胶层为电子束固化胶，此处采用电子束固化方式；若胶层采用热固化胶，此处采用热固化方式。
步骤S6）沿着相邻两个胶框的交界处，将所述复合玻璃板切割成至少一量子点材料玻璃板。每一切割线皆为两个胶框之间的连接处，由于胶框为环状结构，其中的量子点材料也被密封良好。
步骤S7）对所述量子点材料玻璃板进行磨边处理，切割后的玻璃板边缘处有毛刺，需要打磨光滑。
经过步骤S1）-S7）的工艺过程，即可以制成合适的量子点材料玻璃板，接下来只要进行包装出货即可。
如图4所示，现有技术中的量子点材料玻璃板100包括第一无效区域101、第二无效区域102；本实施例制成量子点材料玻璃板200包括第一无效区域201、第二无效区域202；相同尺寸的两块量子点材料玻璃板，其结构不同，二者两部分无效区域的宽度有明显区别。 本实施例制成的量子点材料玻璃板200与现有技术中的量子点材料玻璃板100对比，无效区域的宽度明显减小，使得玻璃板上可以显示影响的有效区域更大，适合窄边框的设计理念。
本发明的优点在于，可以有效封装纳米级的量子点材料，有利于提高色域，增强显示效果；同时，大幅减小量子玻璃板无效发光区域的宽度，可适于窄边框模组。本发明根据胶框的位置将整体玻璃板切割成多个量子玻璃板，可以大幅提高生产效率，降低加工成本。本发明只要对现有设备进行简单改造即可实现，操作方便，灵活性高，工艺改造成本较低，适合大规模推广应用。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
