本发明的实施方式
下面详细描述本申请的实施方式,所述实施方式的示例在附图中示出,其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施方式是示例性的,仅用于解释本申请,而不能理解为对本申请的限制。
请参阅图1,图1为本申请提供的显示装置的第一种实施方式的结构示意图。本申请提供一种显示装置1,包括背光模组10、防窥膜20以及显示面板30。防窥膜20设置在背光模组10的出光侧的表面上,防窥膜20包括第一区域201和第二区域202,显示面板30设置在防窥膜20上,进一步的,显示面板30设置在防窥膜20的出光侧的表面上。背光模组10发出的光线经第一区域201后形成多个沿第一方向排列的第一子发光区203,背光模组10发出的光线经第二区域202后形成多个沿第二方向排列的第二子发光区204。在一些实施例中,该第一方向与第二方向垂直。
本申请提供的显示装置1,在背光模组10的表面上设置防窥膜20,该防窥膜20包括第一区域201和第二区域202,背光模组10的光线经过防窥膜20后,可以形成多个沿第一方向排列的第一子发光区203以及多个沿第二方向排列的第二子发光区204,因此,本申请提供的显示装置能够同时实现横屏显示和竖屏显示。
在一些实施例中,请参阅图2,图2为图1所示的背光模组的平面示意图。第一区域201包括多个第一子区域201A,第二区域202包括多个第二子区域202A。第一子区域201和第二子区域202A在列方向上交替排列,第一子区域201和第二子区域202A在行方向上交替排列,如图2所示。
进一步的,第一子区域201A包括多个沿第一方向排列的第一遮光条2011A,第二子区域202A包括多个沿第二方向排列的第二遮光条2021A。在实际使用过程中,背光模组10向显示面板30提供光线。背光模组10发出的光线经过第一子区域201A后形成多个沿第一方向排列的第一子发光区203,背光模组10发出的光线经过第二子区域202A后形成多个沿第二方向排列的第二子发光区204,即,光模组10发出的光线经过第一子区域201A后,由于第一子区域201A上有多个沿第一方向排列的第一遮光条2011A,第二子区域202A上有多个沿第二方向排列的第一遮光条2021A,因此,背光模组10发出的部分光线被多个沿第一方向排列的第一遮光条2011A遮挡,背光模组10发出的部分光线被多个沿第二方向排列的第二遮光条2021A遮挡,从而形成多个沿第一方向排列的第一子发光区203,以及形成多个沿第而方向排列的第一子发光区204。
在一些实施例中,多个第一遮光条2011A间隔排布,多个第二遮光条2021A间隔排布,且相邻第一遮光条2011A之间的距离等于相邻第二遮光条2021A之间的距离。
例如,多个第一遮光条2011A间隔排布,且相邻第一遮光条2011A之间的距离等于1微米,多个第二遮光条2021A间隔排布,且相邻第二遮光条2021A之间的距离也等于1微米,在实际使用时,背光模组10经过第一子区域201A后形成的多个第一子发光区203的发光亮度,等于背光模组10经过第二子区域202A后形成的多个第二子发光区204的发光亮度,即,背光模组10发出的光线经过第一子区域201A,并射入显示面板30后所形成的第一显示画面的亮度,与背光模组10发出的光线经过第二子区域202A,并射入显示面板30后所形成的第二显示画面的亮度相等,因此,提高了显示装置1的显示效果。
在一些实施例中,每个第一子区域201A的面积均相等,每个第二子区域的面积202A均相等,且第一子区域201A的面积等于第二子区域202A的面积。
比如,每个第一子区域201A的面积均为5平方毫米,每个第二子区域的面积202A也均为5平方毫米,这样便于工程设计,进而提高显示装置1的生产效率。
进一步的,请继续参阅图1以及图2,为了使显示装置1能够同时实现横屏显示和竖屏显示,可以采用多个光源分区域调节第一子区域201A和第二子区域202A发出的光线,即可以采用直下式背光模组,也即,在一些实施例中,背光模组10可以包括底板101、胶框102、扩散板103、第一光源104以及第二光源105。
其中,底板101与扩散板103相对设置,胶框102设置在底板101与扩散板103之间,且扩散板103通过胶框102与底板101连接。多个第一光源104和多个第二光源105均设置在底板101朝向扩散板103的表面上,每个第一光源104均对应一个第一子区域201A,每个第二光源105均对应一个第二子区域202A。
比如,背光模组10包括5个第一光源104以及5个第二光源105,防窥膜20具有5个第一子区域201A以及5个第二子区域202A,在实际使用过程中,当某个第一光源104或某个第二光源105出现故障时,不会影响到其余第一光源104以及第二光源105,并且,只需要更换损坏的第一光源104或第二光源105,不会造成其余第一光源104以及第二光源105的浪费。
另外,还需要说明的是,第一光源104和第二光源105可以同时发光,也可以不同时发光,即,在一些实施例中,请参阅图3,图3为本申请提供的显示装置的第二种实施方式的结构示意图,图3的显示装置1与图1的显示装置1的区别在于:显示装置1还包括控制模组40。
其中,多个第一光源104通过第一连接线501与控制模组40连接,控制模组40用于控制多个第一光源104发光或不发光。多个第二光源105通过第二连接线502与控制模组40连接,控制模组40用于控制多个第二光源105发光或不发光。
比如,该显示装置1具有三种工作模式,包括:第一模式、第二模式以及第三模式。在第一模式时,第一光源104发光,第二光源105不发光。在第二模式时,第一光源104部发光,第二光源105发光。在第三模式时,第一光源104发光,第二光源105发光。具体根据实际情况进行设置,在此不再赘述。
即,在一些实施例中,在显示装置1处于第一模式下时,控制模组40控制多个第一光源104发光,并控制多个第二光源105不发光。在显示装置1处于第二模式下时,控制模组40控制多个第二光源105发光,并控制多个第一光源104不发光。在显示装置1处于第三模式下时,控制模组40控制多个第一光源104和多个第二光源105发光。
在一些实施例中,第一光源104和第二光源105均为发光二极管或冷阴极荧光灯管。
本申请提供的显示装置1,在背光模组10的表面上设置具有第一区域201和第二区域202的防窥膜20,背光模组10的光线经过防窥膜20后,可以形成多个沿第一方向排列的第一子发光区203以及多个沿第二方向排列的第二子发光区204,因此,本申请提供的显示装置能够同时实现横屏显示和竖屏显示。
另外,在一些实施例中,请参阅图4,图4为本申请提供的显示装置的第三种实施方式的结构示意图。本申请还提供一种显示装置1,图3的显示装置1与图1的显示装置1的区别在于:背光模组10包括胶框110、光源120、导光板130、反射片140和光学膜片150。
反射片140设置在胶框110的底部,光源120、导光板130以及光学膜片150均设置在胶框110内。光源120位于导光板130的入光处,光学膜150片位于导光板130的出光处。
在一些实施例中,第一区域201的面积等于第二区域202的面积,如图5所示。
本申请提供的显示装置1,在背光模组10的表面上设置具有第一区域201和第二区域202的防窥膜20,背光模组10的光线经过防窥膜20后,可以形成多个沿第一方向排列的第一子发光区203以及多个沿第二方向排列的第二子发光区204,因此,本申请提供的显示装置能够同时实现横屏显示和竖屏显示。
以上对本申请实施例提供的显示装置进行了详细介绍,本文中应用了具体个例对本申请的原理及实施方式进行了阐述,以上实施例的说明只是用于帮助理解本申请。同时,对于本领域的技术人员,依据本申请的思想,在具体实施方式及应用范围上均会有改变之处,综上所述,本说明书内容不应理解为对本申请的限制。
