具体实施方式
本申请实施例所述的显示面板尤指矢量像素显示面板，矢量像素显示面板通常包括至少一个的矢量像素，通过控制矢量像素的发光亮度和灰阶可以实现画面的显示。在介绍本申请实施例的技术方案之前，首先对矢量像素做如下介绍。
图1是矢量像素的发光示意图。参见图1，矢量像素100是一种满足预设条件的光学器件。该预设条件可以是：第一，矢量子像素窄光束，也就是说相对于较大的显示面积，可以将矢量像素100近似看成为由一个个发光的光源(矢量子像素)构成，每个光源可向空间发射窄光束；矢量子像素向空间发射的光束有如下特点：矢量子像素发出的光束可以理解为以光源为圆心的圆锥体(参见图1)；如果以光强下降到此光束的百分之五十为该光束边界，以光源为圆心，能包括所有边界的最小空间球面角度小于10°，通常仅为1°；第二，矢量像素100可以向多个可被区分的方向上进行投影，换句话说，每个矢量子像素的出射光束80的方向不同(参见图1)；第三，矢量像素100可以同时向至少两个方向上发射光束，也就是说，矢量像素100中可能存在至少两个矢量子像素同时工作，每个矢量子像素的工作情况可以被单独控制；第四，矢量像素100的光束 亮度可以调节，即一个矢量像素100中每个矢量子像素发射光束的亮度是可以调节的。矢量像素100由至少两个矢量子像素构成，每一个矢量子像素发出的光束具有一定指向性。由矢量像素发光的显示装置通常包括人眼追踪模块，首先根据人眼追踪模块确定用户眼睛的位置，然后确定需要被点亮的矢量子像素，该矢量子像素的光束直接朝向人眼所在位置。
示例性的，本申请的任一实施例中，矢量像素由密集显示器件和光学组件构成。其中，密集显示器件由至少两个发光元件构成，每个发光元件可称为一个矢量子像素，每个矢量子像素发出的光经光学组件调制后可以形成指向空间特定方向的光束。
需要说明的是，矢量像素还可以通过其他方式实现，本申请实施例对此不作限定，凡是采用下述方案扩展矢量像素的视角的方案均在本申请的保护范围之内。
本申请实施例通过增设反射组件扩展矢量像素的视角，在此将矢量像素和反射组件的组合称之为矢量像素单元。示例性的，显示面板包括至少一个矢量像素单元。图2是本申请一实施例提供的矢量像素单元的结构示意图，参见图2，矢量像素单元10包括矢量像素100(如图2所示密集显示器件110和光学组件120)和反射组件(如图2所示第一反射镜210)，反射组件至少设置为反射矢量像素发出的光束；矢量像素单元10发出的光束所形成的视角为扩展视角30(如∠A”OB”)，矢量像素发出的光束所形成的视角为原始视角40(如∠A’OB’)，扩展视角30大于原始视角40。
需要说明的是，图2所示矢量像素单元10的结构仅为本申请其中一个实施例提供的矢量像素单元10的结构，在此仅用于示例性地展示矢量像素单元10的组成部件，并非对其结构的限定。
其中，反射组件除了能够反射矢量像素发出的光束以外，还可以具有其他功能，例如还可以透射矢量像素发出的一部分光束。本申请实施例主要利用反射组件的反射功能改变矢量像素发出的光束的方向，以求扩展矢量像素发出光 束所形成的视角，使显示面板能够满足用户大角度观看的需要。
矢量像素可以发出指向空间多个方向的光束，因此，矢量像素发出的光束所形成的视角即人眼所能看到的矢量像素发出的光束的最大空间分布角度。其中，原始视角表示未设置反射组件时矢量像素发出的光束的最大空间分布角度。扩展视角表示矢量像素单元(设置反射组件改变光束方向后的矢量像素)发出的光束的最大空间分布角度。从图2可以看出，经反射组件改变光束出射方向后，矢量像素发出光束的扩展视角大于其原始视角。后续将详细介绍反射组件的类型及其设置位置和作用机理，在此不再赘述。
如此设置，当显示装置根据人眼追踪模块确定人眼所在位置与显示面板出光面的法线夹角为大角度(例如近90°)时，即可选择合适的矢量子像素发光，该矢量子像素出射的光束经光学组件以及反射组件后可以指向人眼，使人眼观测到该被点亮的矢量子像素，从而满足了用户大角度观看的需要。
本申请实施例通过为矢量像素配置反射组件以组成矢量像素单元，利用反射组件改变矢量像素发出的光束的方向，使矢量像素单元发出的光束所形成的扩展视角大于矢量像素发出的光束所形成的原始视角，从而扩展了相关技术中的矢量像素出射光束的最大空间分布角度，使显示面板能够满足用户大角度观看的需要。
下面介绍3种矢量像素单元10的结构，并详细说明其扩展矢量像素发出的光束的视角的机理。
可选的，反射组件包括反射镜组件，即反射组件仅具备反射功能。示例性的，图4是本申请又一实施例提供的矢量像素单元的结构示意图，图2和图4分别示出了反射组件为反射镜组件时的两种实现方式。图3是图2所示矢量像素单元的工作原理示意图，图5-图7是图4所示矢量像素单元的工作原理示意图。在此，首先结合图2和图3介绍第一种矢量像素单元的结构及其工作机理。
参见图3，矢量像素包括密集显示器件110和光学组件120；密集显示器件110包括至少两个发光元件，至少两个发光元件包括第一发光元件111和第二发 光元件112，第一发光元件111发出的光束经光学组件120出射后形成第一原始光束(如AA’)，第二发光元件112发出的光束经光学组件120出射后形成第二原始光束(如BB’)；第一原始光束和第二原始光束形成原始视角40(如∠A’OB’)；第一发光元件111发出的光束经光学组件120和反射镜组件(如第一反射镜210)出射后形成第一扩展光束(如ACA”)，第二发光元件112发出的光束经光学组件120和反射镜组件(如第一反射镜210)出射后形成第二扩展光束(如BDB”)；第一原始光束(如AA’)、第二原始光束(如BB’)、第一扩展光束(如ACA”)以及第二扩展光束(如BDB”)中的任意两条光束形成多个第一视角，多个第一视角中的最大值为扩展视角30(如∠B’OB”)。
密集显示器件中至少包括两个发光元件，在此，以第一发光元件111和第二发光元件112表示所有发光元件中出射光束的空间指向角最大的两个发光元件，其中，光束的空间指向角可以理解为该光束与发光元件的出光面的垂线(即发光元件的出光面的法线)之间的夹角。如此，由第一发光元件111出射的第一原始光束(AA’)和第二发光元件112出射的第二原始光束(BB’)所形成的视角即矢量像素发出的光束的最大空间分布角度，即原始视角40。由于密集显示器件中的其他发光元件发出的光束均位于原始视角40内，因此，在此仅以第一发光元件111和第二发光元件112为例，介绍矢量像素的视角扩展机理。
示例性的，图3所示结构中，反射镜组件包括至少一个第一反射镜210；至少一个第一反射镜210设置于密集显示器件110和光学组件120之间，第一反射镜210的反射面与密集显示器件110的底面相交；第一发光元件111发出的光束经第一反射镜210反射，再经光学组件120出射后形成第一扩展光束(ACA”)；第二发光元件112发出的光束经第一反射镜210反射，再经过光学组件120出射后形成第二扩展光束(BDB”)。
本实施例中，第一反射镜210设置于密集显示器和光学组件120之间，第一反射镜210设置为反射发光元件发出的光。图3仅以一个反射镜组件包括一个第一反射镜为例进行示意。可以理解的，由于发光元件(例如发光二极管) 发出的光是发散的，因此，发光元件发出的一部分光束会直接经光学组件120出射，形成原始光束；发光元件发出的另一部分光束会先照射到第一反射镜210上，被第一反射镜210反射，然后再经光学组件120出射，形成扩展光束。例如，第一发光元件111发出的光束经第一反射镜210反射，再经光学组件120出射后形成第一扩展光束(ACA”)，第二发光元件112发出的光束经第一反射镜210反射，再经过光学组件120出射后形成第二扩展光束(BDB”)。从图3可以看出，矢量像素单元10发出的光束所形成的扩展视角30(∠B’OB”)大于矢量像素发出的光束所形成的的原始视角40(∠A’OB’)，矢量像素发出光束的最大空间分布角度得到扩展。
参见图2，可选的，至少两个发光元件包括多个发光元件，多个发光元件形成发光元件阵列(图2未示出)；至少一个第一反射镜210围绕发光元件阵列设置，且至少一个第一反射镜210的反射面均与密集显示器件110的底面垂直。
示例性的，发光元件阵列的形状可以为任意多边形，例如，矩形。可选的，反射镜组件可以包括多个第一反射镜210，多个第一反射镜210围绕发光元件阵列设置，每个第一反射镜210的边长与发光元件阵列中对应边的边长相等。以矩形设置的发光元件阵列为例，通过将第一反射镜210围绕发光元件阵列设置，可以使发光元件发出的光同时被4面第一反射镜210反射，反射光束经光学组件120出射后可形成4个指向不同方向的第一光束，从而形成立体光束，满足用户从任一位置大角度(用户与显示面板法线之间的夹角)观看的需要。设置第一反射镜210的反射面与密集显示器件110的底面垂直，可使工艺更为简单，也更有利于设计每一个发光元件最终出射光束的方向。
需要说明的是，虽然增设第一反射镜210后，每个发光元件会从光学组件120处出射5束光束(4束扩展光束和1束原始光束)，但是，由于矢量子像素出射光束的发散角仅为平面角1°左右，因此，非用户观看位置处的出射光束(非目标光束)会产生视觉干扰的几率很小，可忽略不计。
下面，结合图4-图7介绍第二种矢量像素单元的结构及其工作机理。参见 图4，可选的，反射镜组件包括中空锥台220，中空锥台220包括第一开口221、第二开口222以及连接第一开口221和第二开口222的锥台侧壁223，中空锥台220包括相对设置的第一表面和第二表面以及相对设置的第三表面和第四表面，第一表面与第一开口位于同一平面，第二表面与第二开口位于同一平面，第三表面为锥台侧壁的内表面，第四表面为锥台侧壁的外表面，第一表面、第二表面和第三表面设置有吸光膜，第四表面设置有第二反射镜2231；中空锥台220设置于矢量像素的出光面上，且第二开口222位于第一开口221背离矢量像素的出光面的一侧，第二开口222在矢量像素的出光面上的垂直投影覆盖第一开口221在矢量像素的出光面上的垂直投影；第一发光元件发出的光束经光学组件120出射，再经第二反射镜2231反射后形成第一扩展光束(未示出)；第二发光元件发出的光束经光学组件出射，再经过第二反射镜2231反射后形成第二扩展光束(未示出)。
与上一实施例的区别在于，本实施例中第二反射镜对经过光学组件120调制后出射的光进行反射，而上一实施例中第一反射镜210直接对发光元件发出的光进行反射，然后再经过光学组件120出射。
如前所述，经光学组件120调制后的光束指向一特定方向，可视为近平行光束，且不同发光元件发出的光束经光学组件调制后的空间指向角不同。在此，图5-图7以具有不同空间指向角的出射光束为例，示出了该光束的空间指向角被扩展的机理。需要说明的是，图5-图7仅示出了发光元件发出的光束经光学组件120出射以后的光路示意图。从图5-图7可以看出，从光学组件120的出光面出射的光束被锥台侧壁223的第二反射镜2231反射，从而改变出光方向，使其空间指向角增大。可以理解的，若任一矢量子像素出射光束的空间指向角增大，那么，矢量像素出射的光束所形成的原始视角即可得到扩展，使显示面板满足用户大角度观看的需要。
图5和图6示出了出射光束的空间指向角小于锥台侧壁223倾斜角时的光路示意图，锥台侧壁223倾斜角为图5及图6中锥台侧壁223与光学组件120 的出光面的法线的夹角∠E，其中一部分原始光束60直接从中空锥台220的开口和外侧射出，另一部分原始光束60被第二反射镜2231反射后形成扩展光束70，扩展光束70的空间指向角大于原始光束60的空间指向角。图7示出了出射光束的空间指向角大于于锥台侧壁223倾斜角时的光路示意图，可以看到扩展光束70几乎沿水平方向出射，扩展光束70的空间指向角大于原始光束60的空间指向角。从图5-图7可以看出，本方案能够增加任意出射光束的空间指向角，因而可以扩展矢量像素的视角。
由于从光学组件120出光面出射的光束的空间指向角各不相同，本实施例通过在锥台侧壁223的第一表面、第二表面和第三表面设置吸光膜，使得进入中空锥台220内部的部分光束可以被吸光膜吸收(参见图7)，从而减小了非目标光束的干扰。此外，示例性的，第一开口221和第二开口222的形状可以为矩型，可以与显示面板的形状对应，如此，从光学组件120出光面出射的光束可以被多个第二反射镜2231反射，从而形成多束扩展光束。参照上一实施例的描述，由于各光束的发散角都很小，因此，为了产生朝向人眼的大空间指向角的光束而产生的其他方向的光会产生视觉干扰的几率很小，可以忽略不计。
可选的，第一开口221和第二开口222平行设置，且第一开口221和第二开口222之间的间距为第一预设距离；锥台侧壁的第四表面与矢量像素的出光面(即光学组件120出光面)之间具有第一预设夹角(即∠E的余角)。
通过合理设置中空锥台220的高度、锥台侧壁223的倾斜角度以及第一开口221和第二开口222的边长，可以实现均衡各方向的出光亮度，本领域技术人员可自行设定第一预设距离和第一预设夹角，本申请实施例对此不作限定。
综上，反射组件可以由反射镜组件构成，可以设置于密集显示器件与光学组件之间，也可以设置于光学组件(矢量像素)的出光侧。除上述由反射镜组件构成反射组件的方案以外，可选的，反射组件包括半透半反组件；矢量像素发出的光束经半透半反组件反射后出射的光束所形成的视角为反射视角50，矢量像素发出的光束经半透半反组件透射后出射的光束所形成的视角为原始视角 40；反射视角50与原始视角40交叠，扩展视角30为原始视角40与反射视角50之和。
因为半透半反组件可以使一部分入射光透过，另一部分光被反射，以改变一部分光束的方向，所以，只要合理设置半透半反组件的位置，使反射光束和透射光束交叠，即可达到扩展矢量像素视角的目的。
示例性的，图8是本申请又一实施例提供的矢量像素单元的结构示意图及其工作原理示意图。参见图8，可选的，半透半反组件包括第一半透半反射镜230；第一半透半反射镜230设置于矢量像素100的出光侧，第一半透半反射镜230覆盖矢量像素100发出的原始视角40内的光束，且第一半透半反射镜230的反射面面向矢量像素100的出光面，第一半透半反射镜230的反射面与矢量像素100的出光面相交。
如图8所示，通过在矢量像素出光侧的前方设置第一半透半反射镜230，可以使矢量像素发出的原始视角40内的一部分光束直接透过第一半透半反射镜230出射到空间，该部分光所形成的视角仍为原始视角40，另一部分光束则经第一半透半反射镜230反射改变传播方向，该反射的光束形成反射视角50，且反射视角50与原始视角40之间存在交叠。如此，反射视角50与原始视角40之和即为扩展视角30，从而实现了扩展矢量像素视角的目的，使显示面板满足用户大角度观看的需要。
从图8可以看出，该方案中增加的反射视角内出射光束的虚拟光源位置位于矢量像素100相对于第一半透半反射镜230的对称的虚像位置100’处，如此，矢量像素在半透半反射镜的虚像可作为光源像素使用，这相当于增加了矢量子像素的数目，基于此原理，可以利用半透半反射镜以及反射镜增加显示面板的显示层数，实现3D视觉效果。示例性的，图9是本申请又一实施例提供的显示面板的结构及其多层显示效果示意图，参见图9，可选的，显示面板为透明显示面板，显示面板还包括显示叠加组件，显示叠加组件包括第三反射镜02和第二半透半反射镜03；第三反射镜02设置于显示面板的非显示侧，且第三反射镜 02的反射面面向显示面板的非显示面，第三反射镜02的反射面与显示面板的显示面平行；第二半透半反射镜03设置于显示面板的显示侧，且第二半透半反射镜03的反射面面向显示面板的显示面，第二半透半反射镜03的反射面与显示面板的显示面之间相距第二预设距离且具有第二预设夹角，需要说明的是，将经过第二半透半反射镜03的底边且与显示面板的显示面平行的平面称为第一平面，则第二预设距离指的是第一平面和显示面板的显示面之间的距离。
参见图9，矢量像素单元10所在区域构成显示面板的发光区域，该发光区域内可以设置至少一个矢量像素单元10，用来显示待显示的图像，相应的，该发光区域可称之为矢量像素显示屏01，矢量像素显示屏01为透明显示屏，以矢量像素显示屏01的出光面表示显示面板的显示面，以矢量像素显示屏01的非出光面表示显示面板的非显示面。
本实施例中，第三反射镜02设置于矢量像素显示屏01非出光面的一侧，第三反射镜02与矢量像素显示屏01平行设置，且与矢量像素显示屏01距离很近几乎可以忽略不计。第二半透半反射镜03设置于矢量像素显示屏01出光面的一侧，且与矢量像素显示屏01的出光面之间相距第二预设距离且具有第二预设夹角。可选的，第二预设距离小于10mm，第二预设夹角小于5°。
如上所述，当人眼追踪模块确定用户的瞳孔位置后，可以确定矢量像素中需要被点亮的矢量子像素。示例性的，参见图9，假设P1位置处的矢量像素单元10的多个矢量子像素被点亮，其中，某一个矢量子像素发出的光束可沿光线1直接透过第二半透半反射镜03到达用户的眼睛，另一个矢量子像素发出的光束首先被第二半透半反射镜03反射后到达第三反射镜02，再经第三反射镜02反射后沿光线2到达用户的眼睛。示例性的，图9中虚像A是矢量像素显示屏01经第二半透半反射镜03透射后所成的虚像，此时得到的虚像A不能被处于第二半透半反射镜03一侧的用户观看到。虚像B为虚像A经第三反射镜02反射后所成的虚像，当用户和显示屏处于比较暗的环境中时，眼睛就可以看到在虚像B的位置有一层显示效果。这是因为，矢量子像素发出的光束发散角很小， 而形成虚像B的矢量子像素集合与人眼直接观看到的矢量像素显示屏01的矢量子像素集合不相同，因此，用户只能在矢量像素显示屏01上看到发出光线1的矢量子像素而不会看到发出光线2的矢量子像素，而在虚像B处只能看到形成光线2的矢量子像素虚像而不会看到发出光线1的矢量子像素虚像，从而实现了增加显示层的效果。
同理虚像B依次经第二半透半反射镜03和第三反射镜02后会在虚像B后方再形成新的显示层，依此类推，点亮N个矢量像素子像素就可以形成N个显示层。
需要说明的是，由于被点亮的矢量子像素是根据人眼追踪模块来确定的，因此确定被点亮的矢量子像素经第二半透半反射镜03以及第三反射镜02作用后，均可以进入到用户的瞳孔。
需要说明的是，在通过增设的第二半透半反射镜03和第三反射镜02来增加显示层的方案中，人眼追踪模块可以根据用户的瞳孔位置，确定矢量像素显示屏01上需要被点亮的矢量子像素，通常被点亮的矢量子像素发射的光线在镜面发生反射后不会影响前一层的显示。但是，由于矢量像素子像素发光光束有一定的发散角，那么第N+1层的子像素光束宽度会大于第N层的子像素的光束宽度，此时可能会发生显示层扩展冲突。参见图9，在用户距离矢量像素显示屏01的距离较远时，可能出现经镜面反射后出射的光线2可能经过P1点且光线的传播方向几乎相同，此时的观看效果就会出现P1点和P2点相互遮挡影响。为了避免扩展显示层存在冲突的情形，现提出以下扩展冲突处理规则：示例性的，在显示的过程，若显示装置中的处理模块检测到两个矢量子像素亮度一致时，则将两个矢量子像素均点亮；若矢量子像素的亮度不一致时，则点亮用于显示前一显示层的矢量子像素。总的来说，当发现扩展显示层会发生冲突时，要保证前一显示层的亮度大于后面显示层的亮度，以避免扩展显示层冲突，影响用户视觉效果。
还需要说明的是，若要显示较多层数时，可以适当调节显示装置所处的环 境亮度。这是因为当用户所处的环境比较亮时，用户可以在反射镜中观看到用户自身的像以及用户所处环境的像，因此需要对用户所处的亮度情况进行限定，其限定程度可以与扩展显示层数有关，当扩展的显示层亮度大于用户所处的环境亮度时，用户即可看到该显示层。
还需要说明的是，本实施例中，矢量像素可以采用上述任一方法扩展视角，由至少一个矢量像素单元10形成矢量像素显示屏01，在此基础上，再通过增设第二半透半反射镜03和第三反射镜02，实现显示层数目的增加。在实际的产品中，若矢量像素发出的光束所形成的视角足以满足用户观看需要，矢量像素显示屏01中的矢量像素也可以不作扩展视角的处理，即不设置反射组件，本申请实施例对此不作限定。凡是通过半透半反射镜和反射镜配合实现增加显示层效果的方案，均在本申请的保护范围之内。
此外，本申请实施例还提供了一种显示装置，该显示装置包括上述任一实施例提供的显示面板，在此不再赘述。
