Description

三维显示装置
本申请要求在2017年3月24日提交中国专利局、申请号为201710184001.X、发明名称为“一种三维显示装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及三维显示机技术领域，尤其涉及一种三维显示装置。
背景技术
液晶显示面板(Liquid Crystal Display，LCD)具有重量轻、厚度薄、功耗低、易于驱动、不含有害射线等优点，已经广泛应用在电视、笔记本电脑、移动电话、个人数字助理等现代信息设备。但是，由于LCD显示面板自身不发光，因此，需要通过耦合外部光源来实现显示，导致LCD显示装置较厚。
为了适应显示面板轻薄化的发展趋势，在LCD之后出现了有机电致发光二极管(Organic Light-Emitting Diode，OLED)显示面板，其具备自发光，不需背光源、对比度高、厚度薄、视角广、响应速度快、可用于挠曲性面板、使用温度范围广、构造及制程较简单等优异的特性。
随着显示面板的更新换代，现在市场上出现了一种新型的显示技术——微发光二极管(Light-Emitting Diode，LED)显示技术，其也属主动发光器件，且相较于OLED显示面板，其响应速度更快、使用温度范围更广、光源利用率更高、寿命更长、成本更低，这些优势使得微LED显示技术有望成为未来显示技术的主流。

具体实施方式
下面结合附图，对本公开实施例提供的三维显示装置的具体实施方式进行详细的说明。
附图中各膜层的厚度和大小形状不反应显示装置的真实比例，目的只是示意说明本公开内容。
本公开实施例提供的一种三维显示装置，如图1至图3所示，包括：微LED显示面板101，设置于微LED显示面板101出光侧的控光部件102，以及分别与微LED显示面板101和控光部件102电连接的控制部件103；其中，
控制部件103，用于在三维显示模式下，控制微LED显示面板101进行显示，同时控制控光部件102产生与微LED显示面板101相匹配的视差挡板；其中，视差挡板由交替排列的遮光条纹和透光条纹构成。
本发明实施例提供的三维显示装置，由于控制部件103控制微LED显示面板101进行显示的同时，可以控制控光部件102产生与微LED显示面板101相匹配的视差挡板，当微LED显示面板101发出的光线通过视差挡板时，便会实现三维显示。因此，实现了基于微LED显示面板101的三维显示。
可选地，在本公开实施例提供的三维显示装置中，控制部件103具体用于在三维显示模式下，根据检测到的观看者与微LED显示面板101的相对位置关系，控制微LED显示面板101进行横屏或竖屏显示，同时控制控光部件102产生与横屏或纵屏显示相匹配的视差挡板；其中，视差挡板由交替排列的遮光条纹和透光条纹构成。
由于控制部件103可以根据检测到的观看者与微LED显示面板101的相对位置关系，控制微LED显示面板101进行横屏或竖屏显示，因此，实现了微LED显示面板101在横屏或竖屏方向上的二维显示。进一步地，控制部件103还可以在控制微LED显示面板101实现在横屏或竖屏方向上的二维显示的同时，控制控光部件102产生与横屏或纵屏显示相匹配的视差挡板，当微 LED显示面板101发出的光线通过视差挡板时，便会实现在横屏或竖屏方向的三维显示。因此，实现了基于微LED显示面板101的在不同方向上的三维显示。
具体地，以本公开实施例提供的上述三维显示装置为手机为例，当观看者是横屏观看手机时，控制部件103根据检测到的观看者与微LED显示面板101的相对位置关系，控制微LED显示面板101进行横屏显示，同时控制部件103控制控光部件102产生与横屏显示相匹配的视差挡板，从而实现横屏方向的三维显示。同理，当观看者是竖屏观看手机时，控制部件103根据检测到的观看者与微LED显示面板101的相对位置关系，控制微LED显示面板101进行竖屏显示，同时控制部件103控制控光部件102产生与竖屏显示相匹配的视差挡板，从而实现竖屏方向的三维显示。
可选地，在本公开实施例提供的上述三维显示装置中，控光部件102的实现方式可以有多种，例如如图2所示，控光部件102，具体可以包括：相对而置的第一基板201和第二基板202，设置于第一基板201与第二基板202之间的电极结构204以及用于根据电极结构204电压变化实现视差挡板的调光层203。
需要说明的是，在本公开实施例提供的上述三维显示装置中，可以将第一基板201设置于第二基板202与微LED显示面板101之间；或者，如图2所示，还可以将第二基板202设置于第一基板201与微LED显示面板101之间，在此不做限定。以下均以第二基板202位于第一基板201与微LED显示面板101之间为例进行说明。
可选地，为了光线可以透过控光部件102，第一基板201和第二基板202的材料可以为玻璃、聚甲基丙烯酸甲酯等透明材料。
可选地，在本公开实施例提供的上述三维显示装置中，调光层203的材料可以为液晶材料或电致变色材料。当然也可以采用其他方式实现对光线的调节，在此不做限定。
可选地，为了增强控光部件102中调光层203的抗压能力，如图2所示， 控光部件102还可以包括：设置在第一基板201和第二基板202之间的多个透明的隔垫物205。
可选地，在本公开实施例提供的上述三维显示装置中，如图2和图4所示，电极结构204，具体可以包括：设置于第一基板201面向第二基板202一侧的异面交叉且相互绝缘的多个横向条状电极2041和多个纵向条状电极2042，以及设置于第二基板202面向第一基板201一侧的面状电极2043。当然，还可以将面状电极2043设置于第一基板201面向第二基板202的一侧，同时将异面交叉且相互绝缘的多个横向条状电极2041和多个纵向条状电极2042设置于第二基板202面向第一基板201的一侧，在此不做限定。
可选地，为了不影响光线从控光部件102透过，横向条状电极2041、纵向条状电极2042和面状电极2043的材料可以为氧化铟锡ITO、氧化铟锌IZO、石墨烯等透明导电材料，在此不做限定。
可选地，为了保证横向条状电极2041和纵向条状电极2042具有相同的透光性，在本公开实施例提供的上述三维显示装置中，相邻的两条横向条状电极2041之间的间距与相邻的两条纵向条状电极2042之间的间距相同，具体地，可以为几微米。
具体地，可以根据三维显示所需的分辨率和微LED显示面板101的长宽比，合理设置横向条状电极2041的数量和纵向条状电极2042的数量。此外，横向条状电极2041的宽度和纵向条状电极2042的宽度相近，大约为一百微米。
可选地，为了实现各横向条状电极2041与各纵向条状电极2042之间相互绝缘，在本公开实施例提供的上述三维显示装置中，控光部件102，还可以包括：设置于各横向条状电极2041与各纵向条状电极2042之间的绝缘层206。其中，绝缘层206可以为单层结构，也可以为多层结构，在此不做限定。
可选地，为了提高三维显示的亮度，在本公开实施例提供的上述三维显示装置中，如图2所示，还可以包括：设置于微LED显示面板101与控光部件102之间的透明胶层207，以降低控光部件102对微LED显示面板101发 出的光的反射作用，从而提高三维显示的亮度。且该透明胶层207可以为光学胶。
具体地，在本公开实施例提供的上述三维显示装置中，如图1所示，控制部件103，可以包括：捕获元件1031和控制元件1032；其中，
捕获元件1031，用于确定观看者的视线与微LED显示面板101的相对位置，或确定三维显示装置的重力感应方向；
控制元件1032，用于根据确定出的观看者的视线与微LED显示面板101的相对位置，或根据确定出三维显示装置的重力感应方向，确定三维显示装置所需的三维显示方向，之后，控制微LED显示面板101进行横屏或竖屏显示，同时控制控光部件102产生与横屏或纵屏显示相匹配的视差挡板。
具体地，在本公开实施例提供的上述三维显示装置中，捕获元件1031为摄像头或重力传感器。
下面以捕获元件1031为摄像头为例，结合图5a和图5b所示，进行说明采用本公开实施例提供的三维显示装置实现三维显示的详细过程：
摄像头30确定观看者的视线与微LED显示面板101的相对位置；
控制元件(如图5a和图5b未视出)根据确定出的观看者的视线与微LED显示面板101的相对位置，确定三维显示装置所需的三维显示方向；例如图5a确定三维显示装置所需的三维显示方向为横向X，图5b确定三维显示装置所需的三维显示方向为竖向Y；
如图5a所示，当三维显示方向为横向X时，控制元件控制微LED显示面板101进行横屏显示，同时控制控光部件中的各纵向条状电极2042和面状电极2043之间形成正压差，从而控制调光层中的液晶或电致变色材料发生偏转，以形成纵向遮光条纹和纵向透光条纹组成的视差挡板，进而实现横屏三维显示。
如图5b所示，当三维显示方向为竖向Y时，控制元件控制微LED显示面板101进行横屏显示，同时控制控光部件中的各横向条状电极2041和面状电极2043之间形成正压差，从而控制调光层中的液晶或电致变色材料发生偏 转，以形成横向遮光条纹和横向透光条纹组成的视差挡板，进而实现竖屏三维显示。
具体地，在实现三维显示时，在本公开实施例提供的上述三维显示装置中，视差挡板中的遮光条纹和透光条纹分别与微LED显示面板101中的至少一列或一行像素对应。即当遮光条纹和透光条纹为横向条纹时，一个横向条纹对应微LED显示面板101沿横向排列的至少一行像素，当遮光条纹和透光条纹为纵向条纹时，一个纵向条纹对应微LED显示面板101沿纵向排列的至少一列像素。
可选地，为了获得较好的三维显示效果，视差挡板中的遮光条纹和透光条纹分别与微LED显示面板101中的一列或一行像素对应。
具体地，在本公开实施例提供的上述三维显示装置中，如图3所示，视差挡板中的遮光条纹的宽度Wb和透光条纹的宽度Ww相等，且约为几百微米。可选地，视差挡板中的遮光条纹的宽度Wb和透光条纹的宽度Ww等于像素尺寸Wp，即Wb＝Ww＝Wp。
此外，如图6所示，微LED显示面板101与控光部件102形成的视差挡板40之间的距离D与像素尺寸Wp之间的关系如下：
D＝Wp*L/(Q+Wp)
其中，L为观看者的眼睛位置与微LED显示面板101之间的距离，Q为观看者的视点间距，即观看者两眼瞳孔之间的距离。
且以三维显示装置的可视距离为30cm为例，即L＝30cm，D的数值约为1cm，此时，D的数值约为Ww数值的一百倍。
进一步地，试验证明，在本公开实施例提供的上述三维显示装置中，微LED像素所占面积与显示区域总面积的比例为1/100时，即可实现亮度需求。
本公开实施例提供的上述三维显示装置，包括：微LED显示面板，设置于微LED显示面板出光侧的控光部件，以及分别与微LED显示面板和控光部件电连接的控制部件；其中，控制部件，用于在三维显示模式下，控制微LED显示面板进行显示，同时控制控光部件产生与微LED显示面板相匹配的视差 挡板；其中，视差挡板由交替排列的遮光条纹和透光条纹构成。由于控制部件控制微LED显示面板进行显示的同时，可以控制控光部件产生与微LED显示面板相匹配的视差挡板，当微LED显示面板发出的光线通过视差挡板时，便会实现三维显示。因此，实现了基于微LED显示面板的三维显示。
