Description

]¾于固定显示器的量子条的装置 技术领域
本发明渉及液晶显示技术领域， 尤其涉及一种用于固定显示器的量子条的装 置。 背景技术
液晶显示器 (LCD)占据着电视和移动电子产品市场的主导地位。多年以来， 制 造商们专注于不断降低大规模制造液晶显示器 (LCD)的成本， 使得它们成了随处 可见的日用品。
通常，要让液晶显示器 (LCD)具有更丰富的色彩是可以通过技术实现的，不过 成本高昂。例如， 基于有机发光二极管 (OLED)的显示技术也已经出现。这种技术 可以提供更丰富的色彩， 在某些情况下能耗也较低， 不过价格要更高。
而只要添加上一层纳米材料也可以达到同样的效果。 例如嵌入了纳米尺寸球 状量子点的量子条就可以提升显示效果。 加入了它的液晶显示器 (LCD)具有可与 有机发光二极管 (OLED)相媲美的色域， 而在制造工艺上则不需要任何改变，成本 也不会增加太多。
如今移动电子设备上使用的液晶显示器 (LCD)都是以设备背面的一组发光二 极管作为白光光源。 液晶控制光的通过， 滤色片为其增加了色彩。 然而白光光源 价格昂贵， 所以显示屏一般都使用蓝光发光二极管， 覆盖上荧光粉把发出的光转 化为白光。
而上述量子条可以替代荧光粉。 量子条中的量子点可以把部分由背光源发出 的蓝色光转化为红光和绿光。 与传统液晶显示器 (LCD)的背光源所发出的白光相 比， 有更多的红、 绿、 蓝色光透过滤色片， 因而显示更加明亮， 色彩更丰富。
图 : 显示了现有技术中常见的量子条的纵向剖视图； 图 2显示了现有技术中 常见的量子条的沿横截面的剖视图。参照图 2, 量子条 10通常包括位于内部的发 挥作 ffl的功能部分 15和包裹着功能部分 15的封装部分 14, 功能部分 15通常由 构成量子点的材料制成， 封装部分 14通常由玻璃材料制成。
因此参照图 1 , 可以看出量子条 10在其纵向上分为位于中部的发挥作用的有 效区 11和分别位于两侧的长无效区 12和短无效区 13。
根据现有技术中的实际情况， 由于短无效区 13的纵向长度较短， 暂且不会对 显示器的显示效果造成较大影响。 而长无效区 12纵向长度较长， 如果不能合理 设置量子条 10的位置，则长无效区 12可能影响整个背光源所发出的光线的质量， 从而导致整个显示器显示效果达不到要求。
另一方面， 由于技术条件和成本的限制， 量子条 10的纵向长度也受到限制。 如果将其生产得过长， 则会造成成本高昂、 组装难度增大， ^而抬升了生产成本 和失败风险； 如果量子条 10 的纵向长度设计成相对短的， 剣需要相应考虑其拼 接方式和固定方式。 发明内容
