Description

液晶显示器及其液晶显示模组
【技术领域】
本发明涉及液晶显示的技术领域,具体是涉及一种可切换视角的液晶显示模组及其液晶显示器。
【背景技术】
目前,由于使用液晶显示器的移动产品应用的普及,人们对产品的品质与人性化的设计提出了越来越高的要求。有时候,用户需要与他人共享便携式电子设备显示的图像,而有时用户出于对个人隐私的保护又不希望他人看到显示的图像,这就需要有一种能够实现宽、窄视角转换的显示器来同时满足这两种需求。
【发明内容】
本发明实施例提供一种可切换视角的液晶显示模组及其液晶显示器,以解决现有技术中的液晶显示器无法实现宽、窄视角显示转换的技术问题。
为解决上述问题,本发明实施例提供了一种可切换视角的液晶显示模组,所述液晶显示模组包括依次平行且层叠设置的背光单元、液晶显示单元以及视角调节单元,其中,所述背光单元设于底部,用于提供背光光源,所述液晶显示单元设于所述背光单元和所述视角调节单元之间,所述背光单元发出的光依次通过所述液晶显示单元和所述视角调节单元。
根据本发明一优选实施例,所述视角调节单元包括上玻璃基板、下玻璃基板以及设于所述上、下玻璃基板之间的电极和液晶体。
根据本发明一优选实施例,所述电极的数量为多个,且相互间隔设置在所述上玻璃基板和所述下玻璃基板之间,所述电极之间形成多个所述液晶体的容置腔,所述液晶体分别设于所述多个容置腔内。
根据本发明一优选实施例,邻近的电极之间上采用极性相反的电压信号,以在所述邻近电极之间形成水平电场,通过选择在所述电极上是否施加电压信号来实现所述液晶显示模组在宽视角和窄视角之间切换。
根据本发明一优选实施例,所述电极的端面形状为柱状。
根据本发明一优选实施例,所述液晶体为正性液晶材料,所述液晶体的初始采用竖直取向。
根据本发明一优选实施例,所述电极包括基体和在所述基体上设置的导电层。

为解决上述技术问题,本发明还提供一种液晶显示器,所述液晶显示器包括上述实施例中所述的液晶显示模组。
相对于现有技术,本发明提供的液晶显示器及其液晶显示模组,通过在上、下玻璃基板之间设置柱状电极,使相邻电极之间产生水平电场。当在相邻电极之间没有施加电压时,液晶体处于竖直的取向状态,从背光单元射入的光线可以不受影响的(即平行的)穿过视角调节单元,显示为窄视角的画面;而当在相邻电极之间施加电压时,位于期间的液晶体会发生水平偏转,而水平排布的液晶体会对光线产生相位延迟,使平行入射的光线改变原来的传播方向而处于多角度的散射状态,以此会产生宽视角的效果;因此实现了液晶显示器在宽、窄视角之间的切换,使液晶显示器同时具备了视角调整的功能;起到很好的避免隐私泄漏的作用。另外,本发明所采用的方法相比于现有技术,具有制作工艺简便、成本低、宽、窄视角的转换效果好以及操作简单等优点。

具体而言,电极的数量可以为多个,且相互间隔设置在上玻璃基板310和下玻璃基板320之间,相邻电极330之间形成多个液晶体340的容置腔350,优选地,该容置腔350的容积设置为相同;液晶体340分别设于多个容置腔350内。其中,相邻电极330之间采用极性相反的电压信号,以在相邻电极330之间形成水平电场,通过选择在相邻电极330上是否施加电压信号来实现液晶显示模组在宽视角和窄视角之间的切换。
优选地,电极330的端面形状为柱状。当然,在其他实施例中,电极的端面形状可以不限于柱状,譬如可以为长方体等,在本领域技术人员能够理解的范围之内,此处不再一一列举。液晶体340优选为为正性液晶材料,液晶体340的初始状态采用竖直取向。
电极330由基体和在基体上设置的导电层(图中未示)。具体而言,该基体的材质为树脂,导电层通过溅射的方式设置在基体上。
下面对该液晶显示模组分别在宽视角和窄视角显示模式下的工作原理进行简单介绍。
该相邻柱状电极330之间采用极性相反的电压信号,由此产生水平电场。在由电极330间隔出的容置腔350之间注入正性液晶材料,初始状态需要对正性液晶体340进行竖直取向(该竖直方向定义为垂直上、下玻璃基板(310、320)的方向),液晶体340初始处于垂直方向的状态。在窄视角的模式下,不给电极330施加电压,所以正性液晶体340会保持初始的垂直取向性态,如图2所示。此时,从下面(背光单元100)射入的光线,穿过视角调节单元300,垂直取向的液晶体340不会对光线产生相位延迟,平行入射的光线仍然保持原来的方向传播。所以此时不会产生光线散射的效果,显示为2D画面。
在宽视角的模式下,给两层玻璃基板之间的柱状电极330上采用极性相反的电压信号,由此产生水平电场。正性液晶体340由于水平电场的作用,会沿水平方向排布,如图3所示。此时,从下面(背光单元100)射入的光线,穿过视角调节单元300,水平排布的液晶体340会对光线产生相位延迟,即使平行入射的光线改变原来的传播方向,呈现出散射的状态。所以此时会产生宽视角的效果。其中,图2和图3中箭头表示光线的传播情况。
相对于现有技术,本发明提供的液晶显示器及其液晶显示模组,通过在上、下玻璃基板之间设置柱状电极,使相邻电极之间产生水平电场。当在相邻电极之间没有施加电压时,液晶体处于竖直的取向状态,从背光单元射入的光线可以不受影响的(即平行的)穿过视角调节单元,显示为窄视角的画面;而当在相邻电极之间施加电压时,位于期间的液晶体会发生水平偏转,而水平排布的液晶体会对光线产生相位延迟,使平行入射的光线改变原来的传播方向而处于多角度的散射状态,以此会产生宽视角的效果;因此实现了液晶显示器在宽、窄视角之间的切换,使液晶显示器同时具备了视角调整的功能;起到很好的避免隐私泄漏的作用。另外,本发明所采用的方法相比于现有技术,具有制作工艺简便、成本低、宽、窄视角的转换效果好以及操作简单等优点。
另外,本发明实施例还提供一种液晶显示器,该液晶显示器包括上述实施例中的液晶显示模组,而关于液晶显示器的其他部分结构特征在本领域技术人员能够理解的范围之内,此处不再赘述。
以上所述仅为本发明的一种实施例,并非因此限制本发明的保护范围,凡是利用本发明说明书及附图内容所作的等效装置或等效流程变换,或直接或间接运用在其他相关的技术领域,均同理包括在本发明的专利保护范围内。
