Abstract

一种导光板，包括中空的本体，所述本体上设置有若干导光单元，所述导光单元排列形成环形，所述每一个导光单元具有一个光耦合部。导光板的本体上具有环形排列的导光单元，从而使得导光板具有环形的显示区域。本发明还涉及一种包含上述导光板的显示装置。

Description

导光板及显示装置
技术领域
本发明涉及导光板及显示装置，尤其涉及一种动态显示的导光板及显示装置。
背景技术
现有的导光板一般为平板结构或者楔形，其配备线光源或点光源，以实现显示效果。如果想要实现环形动态显示效果，需要设计复杂的电路使得线光源或点光源具有动态效果，如此，增加了设计成本和电路的复杂度，进而也使得显示装置结构复杂。
发明内容
有鉴于此，有必要提供一种结构简单且可实现动态显示的导光板及显示装置。
一种导光板，包括中空的本体，所述本体上设置有若干导光单元，所述导光单元排列形成环形，所述每一个导光单元具有一个光耦合部。
一种显示装置，其包括导光板及若干个光源，所述导光板包括中空的本体，所述本体上设置有若干导光单元，所述导光单元排列形成环形，所述每一个导光单元具有一个光耦合部，每一个所述光耦合部设置有一个所述光源，所述光源发出的光经所述光耦合部进入所述导光单元。
本实施例的的导光板具有环形的本体，本体上具有环形排列的导光单元，从而使得导光板具有环形的显示区域；不同的光源或者光源具有不同的工作状态时，可实现环形的动态显示效果。
附图说明
图1是本发明第一实施例显示装置的示意图。
图2是本发明第二实施例显示装置的示意图。
图3是本发明第三实施例显示装置的示意图。
图4是本发明第四实施例显示装置的示意图。
具体实施方式
下面将结合附图，对本发明作进一步的详细说明。
请参阅图1，本发明第一实施例提供的显示装置10。显示装置10包括导光板11和四个光源12，每一个光源12可单独控制。光源12可以为发光二极管、有机发光二极管、激光二极管等。
导光板11具有一个中空的矩形本体110。本体110的四角分别向内突出形成导光单元111，导光单元111排列成环形。导光单元111具有光耦合部112、出光面113、与出光面113相对的底面(图未示)和侧面114，光耦合部112朝向本体10内部。
每一个导光单元111对应一个光源12，光源12位于光耦合部112处。光源12发出之光经光耦合部112进入导光单元111，被侧面114和底面反射后由出光面113出射。
可选择地，底面和侧面114上设置有微结构；本体11的形状并不限于本实施例的矩形，其可以为三角形、菱形等。
光源12工作时(点亮、熄灭或闪烁等)，导光单元111所对应的本体110便可呈现相应的工作状态。因此，该显示装置10可以选择性使任意光源12工作，或者光源12具有不同的工作状态，从而可使得显示装置10呈现环形的动态视觉显示。
如图2所示，本发明第二实施例提供的显示装置20。显示装置20包括导光板21和若干个光源22。
导光板21具有呈矩形的本体210，本体210向外突出形成若干三角形导光单元211，每一个导光单元211对应一个光源22。
如图3所示，本发明第三实施例提供的显示装置30，显示装置30与显示装置20基本相同，不同之处在于：本体310向内突起形成若干圆弧形导光单元311。
如图4所示，本发明第四实施例提供的显示装置40。显示装置40包括圆环形导光板41和若干光源42。
导光板41包括外环410和内环420，外环410向外突出形成若干第一导光单元411，内环420向内突出形成数量与第一导光单元411相同的第二导光单元421，每一个第一导光单元411和第二导光单元421均对应一个光源42。第一导光单元411和第二导光单元421间隔分布，其形状可以相同也可以不同。
另外，本领域技术人员还可在本发明精神内做其它变化，当然，这些依据本发明精神所做的变化，都应包含在本发明所要求保护的范围的内。
