实施例一
图1为本发明实施例一所提供的一种显示面板的结构示意图。如图1、图2以及图3所示，一种显示面板包括：第一发光区域101以及至少一个反射镜；其中，第一发光区域101包括至少一个矢量像素102；至少一个矢量像素102包括至少一个矢量子像素，矢量子像素发出至少一个角度的入射光线；至少一个反射镜设置在显示区域的第一边缘处，矢量子像素发射的入射光线经至少一个反射镜反射后按照预设的路径射出，形成与矢量子像素相对应的虚像。
需要说明的是，矢量子像素发出至少一个角度的入射光线中的“角度”是指，矢量子像素发射入射光线的圆锥区域的轴线在三维空间内的指向角度；矢量子像素发出预设角度的入射光线，可以被理解为，矢量子像素发出预设方向的入射光线。
继续参见图1、图2以及图3，在介绍本发明实施例技术方案之前，先介绍一下矢量像素102。矢量像素102是满足预设条件的光学器件。预设条件可以是：第一，矢量子像素窄光线，也就是说相对于较大的显示面积，可以将矢量像素 102近似看成为由一个个发光的光源构成；矢量像素102向空间发射的至少一束光线有如下特点：参见图2，矢量像素发出的光线可以理解为以光源为圆心的圆锥体；如果以光强下降到此光线的百分之五十为该光线边界，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度；第二，矢量像素102可以向至少100个可被区分的方向上进行投影；第三，矢量像素102可以同时向两个或两个以上的方向上发射光线，也就是说，矢量像素102中可能存在两个或者两个以上的子像素同时工作；第四，矢量像素102的光线亮度可以调节，即一个矢量像素102中每个矢量子像素发射光线的亮度是可以调节的。
在一些实施例中，可参见图3，矢量像素102是由密集显示器件和光学模块组成，密集显示器件的基础发光单元称为矢量子像素，每个矢量子像素发出的光线经矢量像素的光学模块调制后可以形成指向空间特定方向的光线。由于矢量子像素的光线角通常很小，当利用显示***中设置的人眼追踪模块确定用户的瞳孔位置后，就可以确定被点亮的一个或者多个矢量子像素。在一些实施例中，矢量像素102由至少一个矢量子像素构成，每一个矢量子像素发射出的光线具有一定指向性。
需要说明的是，可以将显示装置中视频播放或者图像展示的界面称为显示界面，也就是本实施例中的第一发光区域101。第一发光区域101的大小以及形状，用户可以根据实际需求进行设置。可选的，第一发光区域101为呈弧形、平面、或者是曲面等设置。第一发光区域101显示的画面可以通过铺设在第一发光区域101的矢量像素102来实现。上文已简单介绍了矢量像素102，可以确定的是，矢量像素102由至少一个矢量子像素构成，每一个矢量子像素可以向不同的角度发出光线，并且在显示装置中可以设置人眼追踪模块，根据用户的瞳孔位置可以确定哪一个矢量像素中的矢量子像素发光。
为了扩大显示界面的显示面积，可以在第一发光区域101的预设位置处设置至少一个反射镜。反射镜是一种利用反射定律工作的光学元器件。反射镜按形状可分为平面反射镜、球面反射镜和非球面反射镜三种；按反射程度，可分成全反反射镜和半透半反反射镜(又名分束镜)。本实施例中，可以采用平面、全反射镜。所述至少一个反射镜的数量可以是一个、两个、或者多个，用户可以根据需要扩大的显示面积来设置反射镜的数量。
反射镜在显示面板中的设置方式可以是：在第一发光区域的至少一个边缘处设置，反射镜的长度与显示面板的边缘相等，反射镜的最小宽度可以满足，使反射镜可以接收到第一发光区域边缘处设置的矢量像素出射的光束。
先介绍一下矢量像素中每个矢量子像素经平面镜反射成像的原理，也就是第一发光区域中矢量像素工作的原理。当用户直接观看显示屏幕上，铺设在显示界面上的矢量像素可以被点亮并且被用户看到。参见图4，示例性的，被点亮的矢量像素102中第一个矢量子像素1021发出的光线可以直接进入用户的眼睛，即用户可以观察到此矢量像素102中第一个矢量子像素1021被点亮。相应的，选择合适的矢量像素102中第二个矢量子像素1022被点亮，即根据人眼追踪装置确定的用户瞳孔位置后，相应的处理装置可以确定合适的第二个矢量子像素1022，第二个矢量子像素1022的光线经平面镜1024反射后改变传播方向进入用户的眼睛，用户就可以看到矢量像素102中第二个矢量子像素1022被点亮。第三个矢量子像素1023发射的光线无法被用户看到。由于可以单独控制矢量像素102中矢量子像素亮暗状态，因此可以认为矢量子像素102和与矢量像子像素相对应的虚像为两个独立的像素。由于矢量子像素的光线角很小，平面镜大小有限，并且观察者距第一发光区域101的距离有限，所以根据人眼追踪设备可以确定的矢量像素中一个子像素可以被用户看到。若经计算矢量像素中一个 子像素发射的出射光线经镜面反射后，反射光线可以射入用户的眼睛，则该矢量子像素直接出射的光线是指向镜面而不是用户的方向，这样用户看到的真实显示屏和经镜面成像后的虚像显示屏是相互独立的，两者的显示像素不会相互影响，从而实现了扩展显示面积的技术效果。
在上述技术方案的基础上，可以将反射镜应用到矢量像素显示屏中，来实现扩大显示面积的技术效果。
以第一发光区域101为曲面为例来介绍该方案，结合图1至图4，曲面屏上设置有矢量像素102，两个反射镜分别设置在曲面型发光区域的曲线边缘处，相应的，第一边缘可以理解为曲线发光区域的曲线边缘。显示***中的人眼追踪模块可以获取用户的瞳孔位置，并将用户的瞳孔位置发送至显示***中的处理装置，处理装置可以根据用户的瞳孔位置确定矢量像素显示屏上待发光的矢量子像素，部分矢量子像素可以经上边缘设置的平面镜反射后形成与部分矢量子像素相对应的虚像，得到第一虚像面1011，相应的，还有部分点矢量子像素可以经下边缘设置的平面镜反射后形成与矢量子像素相对应的虚像，得到第二虚像面1012，此时得到的显示面积可以是显示屏面积的三倍。
还需要说明的是，即使要显示画面为同一副图像，当用户所处的位置不同时，可能被点亮的矢量子像素可能相同也可能不同。是哪一个矢量子像素被点亮主要由设置在显示装置中的处理装置，对人员追踪模块获取到的瞳孔位置以及显示装置的参数信息进行计算，确定被点亮的矢量子像素是哪些。
参见图5，若第一发光区域101为平面型，可以将反射镜103设置在平面型显示屏的左右两侧。用户所处的位置不同，显示装置中设置的人眼追踪模块可以确定用户的瞳孔位置，并根据用户的瞳孔位置确定与用户的瞳孔位置相对应的矢量子像素被点亮。也就是说，可以根据用户所处的位置，选择合适的子像 素点亮使其经平面镜103反射的光线可以进入用户的瞳孔，用户观看矢量像素显示屏的同时也可以透过平面镜看到矢量像素经平面镜所成的虚像，这样就可以达到扩大视野的效果，即此时的显示面积为显示屏显示面积的三倍。
需要说明的是，安装本实施例提供的显示面板的显示装置中还包括人眼追踪模块、以及处理装置。其中，人眼追踪模块用于获取用户的瞳孔位置，处理装置用于根据用户的瞳孔位置确定第一发光区域中待发光的目标矢量子像素。
至少一个反射镜设置在第一发光区域边缘处扩大显示面积的原理是：当矢量子像素发出发射光线且与反射镜之间存在夹角时，发射光线可以经反射镜反射后进入用户的瞳孔，并在反射镜面中形成与发射光线的矢量子像素相对应的虚像，从而扩大了显示面积。
在上述技术方案的基础上，还需要说明的是，由于经反射镜反射后进入用户瞳孔的光线可能存在光能的损失，所以需要对经反射镜反射后用户观看到的矢量子像素进行亮度补偿。此时，显示装置中设置的人眼追踪模块可以根据定位到的瞳孔位置信息，还可以确定用于补偿光能损失的矢量子像素，进而根据显示屏幕上显示的内容对发光的矢量子像素进行亮度的补偿。
本发明实施例的技术方案，通过将至少一个反射镜设置在所述第一发光区域的边缘处，用于将所述矢量子像素发射的入射光线经所述至少一个反射镜反射后按照预设的路径射出，形成与所述矢量子像素相对应的虚像，解决了相关技术中为提高显示屏幕的观看面积，通常会增大显示屏幕的物理面积，当大屏显示时，需要在显示界面上设置较多矢量像素，导致存在成本较高，资源浪费的技术问题，既增大了显示界面面积，又降低了生产成本，并且提高用户体验。
实施例二
在上述技术方案的基础上，为了扩大显示面积还可以将至少两个发光区域进行拼接，在本实施例中以两个发光区域拼接为例。
图6为本发明实施例二所提供的一种显示面板结构示意图。参见图6、图3和图4，该界面面板上还包括：第二发光区域201、至少一个反射镜103设置在第一发光区域101以及第二发光区域201的第二边缘处，用于将至少一个矢量子像素发出的入射光线进行反射出射到用户的瞳孔。需要说明的是，本发明实施例中所提及的第一发光区域、第二发光区域、均是安装有矢量像素的区域，在本实施例中仅是针对平面镜的不同设置方式，将显示面板的发光区域进行划分。
为了扩大矢量像素显示屏的面积，除了采用实施例一所提及到的技术方案，还可以是将至少两个矢量像素显示屏进行组合，也就是将两个发光区域进行组合。
在具体实现中，组合方式可以是将两个矢量像素显示屏，或者多面矢量像素显示屏封装在同一水平面上，还可以是封装在不同的水平面上。在实际应用的过程中，将两个矢量像素显示屏封装在同一个平面上仅是理想的状态，大部分是将两个或者多个面矢量像素显示屏封装在多个平面上。可选的，将两个矢量像素显示屏封装在两个平面上。也就是说，第一发光区域101和第二发光区域201拼接时，封装在不同平面上。继续参见图7，可选的，第二发光区域201设置在第二平面上，第一发光区域101设置在第一平面上，第一平面与第二平面之间互相平行。在一些实施例中，第一平面与第二平面之间存在一定的高度差，可以是第一平面的垂直高度高于第二平面，也可以是第二平面的垂直高度高于第一平面。在本实施例中，可以是第二平面的垂直高度高于第一平面的垂直高度，还可以理解为，以用户所处的观看位置为准，第一水平面近离观看测， 第二水平面远离观看测。在拼接的过程中，只要第一发光区域与第二发光区域不在同一水平面上，不管第一发光区域101与第二发光区域201之间采用怎么样的设置放置，第一发光区域101与第二发光区域201均存在缝隙的问题。
当用户在观看显示界面的过程中，可能出现由于用户与矢量像素显示屏法线方向之间的角度较大，导致看到矢量像素第二发光区域201与第一发光区域101之间的缝隙，从而使显示界面不完整，导致存在用户体验较差的问题。示例性的，参见图7，第一发光区域101与第二发光区域201之间的设置方式可以如图所示，当用户在A视点观看时，用户可以看到完美的显示屏，当用户在B视点观看时，可能会看到第二发光区域201和第一发光区域101之间的缝隙，显示效果较差。在上述技术方案的基础上，可以在第二发光区域201和第一发光区域101之间的缝隙处，设置至少一个反射镜103，继续参见图6，也就是说在第一水平面与第二平面的间隙处垂直设置一个平面镜103。当显示***中的人眼追踪模块，检测到用户的瞳孔位置后，显示***中的处理装置可以根据用户的瞳孔位置确定第二发光区域201中，哪一个矢量子像素经反射镜103作用后，可以进入用户的瞳孔，从而避免用户看到第二发光区域201与第一发光区域101之间的缝隙。也就是说，第二发光区域201上矢量子像素发射的光线出射到反射镜103，可以经反射镜103作用后进入用户的瞳孔，并由于光线的可逆性，可以形成与发光矢量子像素相对应的虚像，这样设置的好处在于有效的遮挡了第二发光区域201和第一发光区域101的缝隙，并且实现了不论用户在处于哪一个位置均可以看到完美的显示屏幕。
本发明实施例还提供了一种显示***，显示***中包括人眼追踪装置、处理装置以及本发明实施例所提供的显示面板，当采用本实施例所提供的显示面板是，可以实现扩大显示面显示面积，广场裸眼3D显示以及提高用户体验的技 术效果。
本发明实施例的技术方案，通过将至少一个反射镜放置在至少两个发光区域的缝隙处，用于将至少一个矢量子像素的发出的入射光进行反射出射到用户的瞳孔，解决了相关技术中为了扩大显示面将至少两个发光区域进行拼接时，若用户所处的位置比较计算时，观看到的显示界面效果不佳的技术问题，实现了通过设置在缝隙处的反射镜既扩大了显示面积，又达到了显示界面的完整性，从而提高了用户体验的技术效果。
