Description

一种显示装置 技术领域
本发明的实施例涉及显示器技术领域， 尤其涉及一种显示装置。 背景技术
遥控技术已经成为当今家用电器中普遍采用的技术，在众多遥控技术中， 红外遥控是比较常用的一种， 如电视机的遥控器通常为红外遥控器。 红外控 制信号作为光信号的一种， 具有方向性。 在使用时， 需使红外遥控器和红外 接收器保持在同一直线上。
图 1和图 2示出了现有技术下的显示装置， 其中， 图 1为现有技术下的 一种显示装置结构示意图， 图 2为图 1所示的显示装置从 A向看到的结构示 意图， 显示装置包括： 显示屏 01 , 设置在显示屏 01周边的不透明边框 02、 设置在不透明边框 02底面的导光件 03 , 该导光件 03的厚度与不透明边框厚 度相同、 以及与导光件 03的入射面 031对应设置的红外接收器 04。 当然， 也 存在另一种结构的显示装置， 导光件 03设置在不透明边框内， 如图 3所示。
上述两种结构的显示装置， 在使用时， 红外遥控器发射出的红外控制信 号经导光件 03传输到红外接收器 04, 从而使红外接收器 04能够接收到红外 遥控器发出的红外控制信号。
本发明的发明人发现， 当前这两种结构的显示装置的下边框有凸起或者 边框过宽， 限制了显示装置的边框的进一步变窄。 发明内容
本发明的实施例提供了一种显示装置， 用以解决惯常技术中显示装置的 下边框过宽的问题。
为解决上述技术问题， 本发明的实施例提供了如下技术方案：
一种显示装置， 包括： 显示屏、 围绕所述显示屏设置的边框， 还包括： 红外接收器； 以及导光件；
其中， 所述导光件具有固定面， 通过该固定面固定至所述边框， 所述导 光件还具有接收端和出光面， 所述接收端形成在所述显示屏的显示侧， 所述 接收端在垂直于所固定到的边框的方向上的宽度比所述出光面的在该方向上 的宽度窄。
所述接收端具有第一接收面和第二接收面， 第一接收面与所述固定面相 交并平行于所述显示屏， 第二接收面与第一接收面相交并与所述固定面相对， 但不与所述显示屏平行。
根据本发明的一个实施例， 所述导光件具有凹槽， 用于容纳所述红外接 收器， 所述红外接收器朝向所述导光件的出光面。
在一些可选的实施方式中， 所述接收端接收红外控制信号并改变其传输 方向以将其传输到所述红外接收器， 且从所述第一接收面到所述出光面， 在 垂直于所述边框的方向上， 所述第二接收面与所述固定面之间的距离逐渐增 大。
在一些可选的实施方式中， 所述第二接收面为弧面。
在一些可选的实施方式中， 所述第二接收面为平面， 且所述第二接收面 与所述接收端的固定面之间的夹角为 30° ~70° 。
在一些可选的实施方式中， 所述导光件由透明材料制成。
在一些可选的实施方式中， 所述透明材料为玻璃、 树脂、 聚曱基丙烯酸 曱酯或塑料。
在一些可选的实施方式中， 所述固定面贴附于所述边框。
在一些可选的实施方式中， 所述导光件与所述边框通过螺釘固定连接。 在一些可选的实施方式中，所述红外接收器通过螺釘固定于所述凹槽内。 在一些可选的实施方式中， 所述红外接收器贴附于所述凹槽内。
本发明提供的显示装置， 通过设置导光件的接收端来改变红外控制信号 的传输方向， 使得在红外接收器的设置位置后移的情况下 （即向靠近显示装 置的背面移动）， 红外接收器同样可以接收到红外控制信号， 且由于接收端在 垂直于所述边框的方向上的宽度比导光件的出光面在该方向上的宽度窄， 人 目艮在看显示屏时， 只能看到导光件较窄的部分， 所以， 本发明提供的显示装 置， 提高了显示装置窄边框的显示效果。 附图说明
为了更清楚地说明本发明实施例的技术方案， 下面将对实施例的附图作 筒单地介绍， 显而易见地， 下面描述中的附图仅仅涉及本发明的一些实施例， 而非对本发明的限制。
图 1为惯常技术提供的一种显示装置结构示意图；
图 2为图 1所示的显示装置的从 A向看的结构示意图；
图 3为惯常技术提供的另一种显示装置结构示意图；
图 4为本发明实施例提供的第一种显示装置的结构示意图；
图 5为本发明实施例提供的第二种显示装置的结构示意图；
图 6为本发明提供实施例的第一种显示装置中的导光件的接收端内的光 路传播图。 具体实施方式
为使本发明实施例的目的、 技术方案和优点更加清楚， 下面将结合本发 明实施例的附图， 对本发明实施例的技术方案进行清楚、 完整地描述。 显然， 所描述的实施例是本发明的一部分实施例， 而不是全部的实施例。 基于所描 述的本发明的实施例， 本领域普通技术人员在无需创造性劳动的前提下所获 得的所有其他实施例， 都属于本发明保护的范围。
请参考图 4, 图 4为本发明实施例提供的第一种显示装置结构示意图，该 显示装置包括： 显示屏 2、 设置在显示屏 2周边的边框 1 , 还包括： 红外接收 器 3; 以及导光件 4;
其中， 所述导光件具有固定面 40, 通过该固定面 40固定至所述边框 1 , 所述导光件 4还具有接收端 42和出光面， 所述接收端形成在所述显示屏的显 示侧， 所述接收端在垂直于所固定到的边框的方向上的宽度比所述出光面的 在该方向上的宽度窄。
在实际中， 通常将导光件设置在边框 1 的底面， 但也可以将导光件设置 在边框的其他面上， 例如， 顶面或者侧面。 边框 1 的底面为显示装置如图 4 所示方向放置时的底面。
根据本发明实施例的导光件的接收端包括第一接收面和第二接收面， 第 一接收面与导光件的固定面相交并平行于所述显示屏的显示侧， 第二接收面 与第一接收面相交并与固定面相对。
此处说明， 接收端 42如图 4所示位置放置时， 接收端 42面向人眼的一 面为接收端 42的第一接收面， 导光件通过固定面固定到边框， 与第一接收面 相交并与固定面相对的一面为第二接收面。 本发明的实施例提供的显示装置，通过导光件 4的接收端 42的第一接收 面和第二接收面来接收红外控制信号并改变其传输方向， 使得在保证红外接 收器 3可以接收到红外控制信号的情况下将红外接收器 3的设置位置后移（即 向靠近显示装置的背面移动 ), 且由于接收端在垂直于所固定到的边框的方向 上的宽度比所述出光面的在该方向上的宽度窄， 从显示屏的正面观看时只能 看到导光件 4较窄的部分（即接收端 42的第一接收面）。
所以， 本发明提供的显示装置， 提高了显示装置窄边框的显示效果。 进一步地， 为了便于红外接收器 3接收到信号， 接收端 42接收红外控制 信号并能够改变红外控制信号的传输方向以将其传输到红外接收器 3 ,且在垂 直于所固定到的边框的方向上，接收端 42的第二接收面与接收端的固定面之 间的距离逐渐增大。
接收端 42的具体结构可以有多种：
请继续参考图 4, 在该实施例中，接收端 42的第二接收面为弧面。 当然， 弧面的形状不限于图 2所示的弯曲形状， 只要第二接收面的弧面满足人眼看 过去， 只能看到导光件 4的最窄的部分（即第一接收面 ), 且接收端 42可将 接收到的红外控制信号传输给红外接收器 3即可。
请参考图 5 , 图 5为本发明的实施例提供的第二种显示装置的结构示意 图， 在该实施例中， 接收端 42的第二接收面为平面， 且接收端 42的第二接收 面与接收端 42的固定面之间的夹角为 30° ~70° 。 例如： 该夹角可以为 30° 、 40。 、 50。 、 60。 、 70。 等， 这里不再——赘述。
为了便于理解接收端 42内的光路传播路线， 下面以图 4所示结构的显示 装置为例， 结合图 6, 对光在接收端 42内的传播路径进行描述， 其中， 图 6 为本发明的实施例提供的第一种显示装置中的导光件的接收端内的光路图。 同时， 为了便于对光路进行描述， 下文引入术语第一界面、 第二界面、 第三 界面， 其分别为对应于第二接收面 421、 固定面 422和出光面 423。
请参考图 6,当遥控器发射的红外光线垂直于第一接收面 420入射时，即， 如图 6所示的第一入射光线 b, 第一入射光线 b不发生任何折射或反射， 直线 进入红外接收器 3;
当遥控器发射的红外光线射入接收端 42的第二接收面 421时， 即为如图 6所示的第二入射光线 c时， 第二入射光线 c将在第一界面 （即第二接收面 421 )发生第一次折射后照射在第二界面 （即固定面 422 )上， 并在第二界面 上发生第一次反射后再次照射在第一界面（即第二接收面 421 )上， 再在第一 界面 （即第二接收面 421 )上发生第二次反射后照射在第三界面 （即出光面 423 )上， 最后在第三界面 （即出光面 423 )上发生第二次折射后入射在红外 接收器 3上。
为提高红外光线的利用率， 希望第二入射光线 b在第二界面 422和第一 界面 421 处的第一次反射和第二次反射都为全反射， 以提高红外光线的利用 率。
全反射指的是光由光密 （即光在此介质中的折射率大的）媒质射到光疏 (即光在此介质中折射率小的）媒质的界面时， 全部被反射回原媒质内的现 象。
当遥控器发射的红外光线未进入接收端 42而射入外界介质面（例如地面、 桌面等） 时， 即为如图 6所示的第三入射光线 d时， 第三入射光线 d将在介 质面上发生第一次反射后入射在第一界面（即第二接收面 421 )上， 在第一界 面上发生第一次折射后入射在第三界面（即出光面 423 )上， 最后在第三界面 上发生第二次折射后入射在红外接收器 3上。
当然， 由于入射光线的角度可以有多种， 不限于以上三种传播方式， 但 总的原理都是光线在接收端内发生反射和 /或折射（除垂直入射光线）后， 入 射在红外接收器上。 本文列举三种具有代表性的光线传播方式， 对于其它角 度的入射光线在接收端内的传播方向， 这里就不再一一赘述。
为方便光线在其中传输， 上述几种结构的导光件由透明材料制成。 进一 步地， 透明材料为玻璃、 树脂、 聚曱基丙烯酸曱酯或塑料。 当然， 透明材料 不限于上述列举的这些， 在这里就不再一一赘述。 若导光件材质为聚曱基丙 烯酸曱酯， 折射率为 1.49, 则入射角度大于等于 42.2° 的光线都会发生全反 射。
可选地，导光件 4的固定面贴附于边框 1的底面。或者导光件 4与边框 1 通过螺釘固定连接。 当然， 导光件 4与边框 1也可以通过卡扣和卡口固定连 接， 卡口可以设置在边框 1的固定面上， 卡扣设置在导光件 4上， 或者卡扣 可以设置在边框 1 的固定面上， 卡口设置在导光件 4上， 这里对于导光件 4 和边框 1的固定方式就不再——赘述。
可选地， 红外接收器 3可以通过螺釘固定于凹槽 41内。 或者红外接收器
3贴附于凹槽 41内。 当然， 同理， 红外接收器 3与凹槽 41也可以通过卡扣和 卡口固定连接， 卡口可以设置在红外接收器 3上， 卡扣设置在凹槽 41内， 或 者卡扣可以设置在红外接收器 3 , 卡口设置在凹槽 41内， 这里对于红外接收 器 3和凹槽 41的固定方式就不再——赘述。
本发明实施例中提供的显示装置可以为液晶电视。 也可以为其它需要红 外遥控的显示装置， 这里就不再——赘述。
以上所述仅是本发明的示范性实施方式， 而非用于限制本发明的保护范 围， 本发明的保护范围由所附的权利要求确定。
