Description

用于固定显示器的量子条的装置及显示器 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 置及显示器。 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 1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 常见的量子条的沿橫截面的剖视图。参照图 2， 量子条 10通常包括位于内部的发 挥作 ^的功能部分 13和包裹着功能部分 13的封装部分 14 , 功能部分 13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 L 可以看出量子条 0在其纵向上分为位于中部的发挥作用的有 效区】】和位于两侧的无效区 12。 如果有效区 11偏移、 旋转、 被遮挡， 则会影响 背光源的发光效果； 如果封装部分 14破损， 则功能部分 13会受到物理性伤害， 或被显示器内部散发的热量所损坏。 可见， 量子条的设置也造成了一些风险， 而 目前现有技术中的液晶显示器并不能有效规避这些风险。
首先， 由于量子条通常采用玻璃封装处理， 因此容易破损； 第二， 由于显示 器工作过程中会散发一定的热量， 量子条可能被该热量伤害； 第三， 在显示器的 制造、 运输、 移动等过程中， 量子条有可能发生移位、 弯曲或偏转等。 上述情况 均会导致整个显示器的背光源所发出的光线不符合要求， 最终导致整个显示器的 显示效果不理想。 发明内容
如上所述， 在现有技术中， 首先， 由于量子条通常采用玻璃封装处理， 因此 容易破损； 第二， 由干显示器工诈过程中会散发一定的热量， 量子条可能被该热 量伤害； 第 ， 在显示器的制造、 运输、移动等过程中， 量子条有可能发生移位、 弯曲或偏转等。 上述情况均会导致整个显示器的背光源所发出的光线不符合要 求， 最终导致整个显示器的显示效果不理想。

主体可以采 适合的材料以对量子条进行物理性防护和隔热保护； 连接结构 将其固定到显示器的固定位置处； 配合面的紧密夹持防止了量子条的位移。

上述技术特征可以各种技术上可行的方式组合以产生新的实施方案， 只要能 够实现本发明的目的。 附图说明
在下文中将基于仅为非限定性的实施例并参考^图来对本发明进行更详细的 描述。 其中：
图 1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；
图 3显示了根据本发明的用干固定显示器的量子条的装置；
图 4显示了根据本发明的用于固定显示器的量子条的装置的进一步的改进。 在图中， 相同的构件由相同的附图标记标示。 ^图并未按照实际的比例绘制。 具体实施方式
下面将参照對图来详细地介绍本发明。 图 3显示了根据本发明的用于固定显示器的量子条 10的装置 20。
装置 20包括装置的主体。 主体具有用于容纳量子条 10的腔体。 主体可以采 用适合的材料以对量子条 10进行物理性防护和隔热保护。
在主体的表面上具有用于夹持量子条 10的配合面，其构成上述腔体的周壁的 一部分。 配合面能够与量子条 10的外表面紧密接合。 在图 3所示的实施例中， 配合面的形状为沿第一直线的第一方向延伸的凹槽。图 3显示的为凹槽的横截面， 在图 3中， 第一方向即垂直于纸面的方向。 因此由图 3的剖视图可见， 配合面的 横截面为圆弧形。 这与现有技术中常见的量子条的形状相适配。
装置 20还包括用于将主体固定到显示器的壳体的连接结构。
可见， 装置 20可以通过配合面来夹持量子条 ), 并通过连接结构将装置 20 的主体以及量子条 10固定到显示器的适当位置处，完成了圏定量子条 10的功能, 同时装置 20的主体包裹量子条 10, 对其进行保护， 防止其破裂或受热过度。 配 合面与量子条】0的夕卜表面紧密接合， 可以防止量子条 10松动， 影响背光源的出 光效果。
在图 3所示的例子中， 主体包括第一主体部分 2i和第二主体部分 22; 而配 合面包括第一配合面 26和第二配合面 27。 量子条 i0被紧密夹持在第一配合面 26和第二配合面 27之间。如此可以防止量子条 10沿其轴向平移、沿其周向旋转 或被偏置、 弯曲， 保证了背光源的出光效果； 同时装置 20 的主体包圈着量子条 10, 只要适当选择主体的材料， 就能够对量子条 10迸行热保护， 防止显示器内 部的散热对量子条 10造成伤害。
在图 3中， 第一配合面 26和第二配合面 27均沿第一方向 （垂直于纸面的方 向） 延伸， 旦在第一方 ^上的相对应的位置处， 第一配合面 26和第二配合面 27 的凹陷方向位于同一第二直线上且指向相反， 所述第二直线垂直于所述第一直 线。 在图 3所示的例子中， 第二直线即沿着虚线 B的方向。 如此设置制造工序最 为简单， 空间结构最为紧凑， 旦与现有技术中常见的量子条的形状相适配。
图 3显示了第一配合面 26和第二配合面 27的横截面。 在图 3中， 第一方向 即垂直于纸面的方向。 因此由图 3的剖视图可见， 第一配合面 26和第二配合面 27的橫截面均为圆弧形。然而， 并不限于此， 它们的横截面也可以为矩形、方形、 梯形、 三角形甚至是多边形， 只要其与量子条 10 的外表面相适配， 能够紧密夹 持量子条 10, 即可达到本发明的目的。 从图 3中可见， 第一主体部分 21包括第一配合面 26和卡钩连接结构 23， 第 二主体部分 22包括第二配合面 27和螺纹连接结构 24。
卡钩连接结构 23包括.从第一主体部分 21上延伸出来的卡接件， 所述卡接件 具有延伸部 29和位于延伸部 29的端部处的弯折端部 28， 延伸部 29和弯折端部 28呈直角或锐角。 如图 3所示， 延伸部 29从第一主体部分 21水平向外延伸， 而 弯折端部 28从延伸部 29的端部处竖直向下延伸。
显示器包括集成到光源板体 30上的多个发光二级管 31。 由图 3可见， 光源 板体 30的边缘顶靠着延伸部 29, 光源板体 30的边缘夹持到弯折端部 28的内 侧。
如此地， 装置 20可以紧固到发光二级管 31的光源板体 30, 有效将量子条 10 圏定到发:光二级管 3】 付近， 以实现整个背光源的功能。 同时可以在发光二级管 31和量子条 10之间保持一定的耦光距离， 以增强光的利用率并使得背光源所发 的光线更加均匀。
图 4显示了装置 20的一个优选的实施例。 在图 4中， 第一主体部分 21和第 二主体部分 22通过多个连接部 25彼此连接， 且多个连接部 25在第一方向 （垂 直于纸面的方向） 上间隔开。
连接部 25可以包括将第一主体部分 21和第二主体部分 22连接起来的单独的 连接件， 或者连接部 25也可以与第一主体部分 21和第二主体部分 22—体式构 造。 采用单独的连接件使得一主体部分 21和第二主体部分 22的装配更加灵活， 生产工序更简单， 成本低廉； 采用一体式构造使得装置 20 能够牢固地固定住量 子条 10, 并对其进行物理性防护和隔热保护。
本发明还提出了一种包括装置 20的显示器。
再次参照图 3 , 显示器包括集成到光源板体 30上的多个发光二级管 3】， 且光 源板体 30的边缘顶靠着延伸部 29， 且光源板体 30的边缘夹持到弯折端部 28的 内侧。 如此地， 第一主体部分 2 Γ可以通过卡接结构紧固到发光二级管 31的光源 板体 30,有效将量子条 10固定到发光二级管 31 近，以实现整个背光源的功能。 同时可以在发光二级管 31和量子条 10之间保持一定的耦光距离， 以增强光的利 ^率并使得背光源所发的光线更加均匀。
参照图 4， 连接部 25位于多个发光二极管 31 的间隙中， 且在与发光二级管 31相对应的位置处间隔开。 如此， 一方面， 连接部 25能够将第一主体部分 21和 第二主体部分 22连接到一起， 以实现对量子条 10的紧密夹持； 同时连接部 25 在与发光二级管 31相对应的位置处间隔开， 如此保证不会阻挡发光二级管 31的 光路， 使得发光二级管 31的光线能够直接投射到量子条】 0上， 保证了整个背光 源能够发出充足 ϋ颜色足够饱满的光线。
第二主体部分 22的螺纹连接结构 24包括螺纹孔和穿过所述螺纹孔的螺钉， 所述第二主体部分 22通过所述螺钉固定到显示器的壳体。 从而， 将整个装置 20 和量子条 10—起紧固到显示器的壳体。
本发明提供了一种用于固定显示器的量子条的装置及显示器， 有助于固定量 子条。 可以配合背光源迸行固定， 通过卡钩连接结构卡住光源板体的边缘， 在发 光二级管和量子条之间留出足够的耦光距离， 保证了:光线的均匀； 同时配合面的 紧密夹持防止了量子条翻转、 平移， 以防影响背:光源的出:光效果， 保证了显示器 的显示质量； 另外， 装置的主体包裹量子条， 起到了热保护的作用。
虽然已经参考优选实施飼对本发明进行了描述， 但在不脱离本发明的范围的 情况下， 可以对其进行各种改进并且可以用等效物替换其中的部件。 本发明并不 局限于文中公开的特定实施例， 而是包括落入权利要求的范围内的所有技术方
