Definitions
- the present application relates to the field of display technology, and in particular to a display device and a display terminal.
- Display technology is developing from two-dimensional display to three-dimensional display.
- the three-dimensional display scheme uses the observer's left and right eyes to observe slightly different two-dimensional images, and then synthesizes a three-dimensional image in the brain. Due to the different positions of the images observed by both eyes and the three-dimensional images synthesized in the brain, long-term observation will cause a conflict between the convergence and accommodation functions of the eye lens (VAC, Vergence and Accommodation Conflict).
- the related technology increases the viewpoint so that a single eye can see the three-dimensional effect, and the positions of the three-dimensional images observed by a single eye and two eyes are consistent, thereby avoiding the conflict between the convergence and accommodation functions, but this will result in a decrease in resolution (PPI, Pixel Per Inch, pixels per inch).

- the present application provides a display device, the display device comprising:
- a micro lens array located on one side of the display surface of the display screen and opposite to the display screen, the micro lens array comprising a plurality of lens structures;

- the distance between any one of the first viewpoint and the second viewpoint and any one of the third viewpoint and the fourth viewpoint is greater than 8 mm. That is to say, the distance between any one of the first viewpoint and the second viewpoint and the third viewpoint is greater than 8 mm, and the distance between any one of the first viewpoint and the second viewpoint and the fourth viewpoint is greater than 8 mm.

Description
本申请要求于2023年11月13日提交的申请号为202311516945.4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。
本申请涉及显示技术领域，尤其涉及一种显示装置及显示终端。
显示技术从二维显示朝着三维显示发展，通常，三维显示方案是利用观察者的左眼和右眼观察到稍有不同的二维图像，然后在大脑中合成三维图像。由于双眼观察到的图像和大脑中合成的三维图像的位置不同，长时间观察会引起眼睛晶状体辐辏和调节功能之间的冲突（VAC，Vergence and Accommodation Conflict）。
为了克服VAC效应，相关技术中通过增加视点使单眼能够看到三维效果，且单眼和双眼观察到的三维影像的位置一致，从而避免了辐辏和调节功能冲突，但是这样会导致分辨率（PPI，Pixel Per Inch，每英寸的像素数）下降。
因此，亟需改善上述技术问题。
本申请提供一种显示装置及显示终端，能够提升显示装置的三维显示的显示分辨率。
为解决上述技术问题，本申请提供的技术方案如下：
本申请提供一种显示装置，所述显示装置包括：
显示屏；
微透镜阵列，位于所述显示屏的显示面一侧且与所述显示屏对置，所述微透镜阵列包括多个透镜结构；
其中，所述显示屏与所述微透镜阵列的间距为第一间距，所述第一间距大于所述透镜结构的焦距且小于2倍所述透镜结构的焦距。
在本申请还提供一种显示终端，显示终端包括显示装置，所述显示装置包括：
显示屏；
微透镜阵列，位于所述显示屏的显示面一侧且与所述显示屏对置，所述微透镜阵列包括多个透镜结构；
其中，所述显示屏与所述微透镜阵列的间距为第一间距，所述第一间距大于所述透镜结构的焦距且小于2倍所述透镜结构的焦距。

下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。此外，应当理解的是，此处所描述的具体实施方式仅用于说明和解释本申请，并不用于限制本申请。在本申请中，在未作相反说明的情况下，使用的方位词如“上”和“下”通常是指装置实际使用或工作状态下的上和下，具体为附图中的图面方向；而“内”和“外”则是针对装置的轮廓而言的。
如图1和图2所示，本申请提供一种显示装置，显示装置包括显示屏11和微透镜阵列12，微透镜阵列12位于显示屏11的显示面一侧且与显示屏11对置，微透镜阵列12包括多个透镜结构120；其中，显示屏11与微透镜阵列12的间距为第一间距g1，第一间距g1大于透镜结构的焦距f1且小于2倍透镜结构的焦距f1。
在本实施例中，显示装置为三维显示装置，可用于观看三维画面。
在本实施例中，显示屏11可以为LCD面板、OLED面板、Mini-LED面板、Micro-LED面板等。显示屏11包括显示区AA，显示区AA设有多个像素。
在本实施例中，微透镜阵列12设置于显示屏11的显示面一侧，微透镜阵列12覆盖显示面。微透镜阵列12包括多个透镜结构120，每一个透镜结构120具有相同的焦距、相同的形状、相同的尺寸。需要说明的是，由于微透镜阵列12的制造工艺的影响，每一个透镜结构的焦距f1、形状、尺寸可能存在一定偏差，此时也应理解为透镜结构120相同。多个透镜结构120可以连接设置，从而简化显示装置与微透镜阵列12的组装工艺。
微透镜阵列12与显示屏11的间距为第一间距g1，需要说明的是，第一间距g1为透镜结构120的光心至显示屏11的显示面之间的间距。多个透镜结构120的光心与显示屏11的显示面的间距相同。
第一间距g1大于透镜结构的焦距f1且小于2倍透镜结构的焦距f1，即f1<g1<2*f1。因此，显示屏11的画面经微透镜阵列12汇聚后形成位于微透镜阵列12背离显示屏11一侧的实像，即显示屏11和实像位于微透镜阵列12的两侧。由于第一间距g1一定时，实像的图形的尺寸相较于虚像的图形的尺寸更小，即实像的每英寸的像素数大于虚像的每英寸的像素数，从而提升显示装置的分辨率。
由于双眼观察到的图像和大脑中合成的三维图像的位置不同，长时间观察会引起VAC效应。
为了克服VAC效应，在本申请的显示装置中，如图1至图3所示，显示屏11包括多个第一像素p1和多个第二像素p2，一个透镜结构120至少对应于一个第一像素p1和一个第二像素p2；其中，第一像素p1发出的光线经透镜结构120汇聚于第一视点，第二像素p2发出的光线经透镜结构120汇聚于第二视点，第一视点和第二视点间隔设置，第一视点和第二视点的间距大于或等于2毫米且小于或等于8毫米。
在本实施例中，一个透镜结构120至少对应于一个第一像素p1和一个第二像素p2，即一个透镜结构120至少在显示屏11的显示面上的正投影至少覆盖一个第一像素p1和一个第二像素p2，第一像素p1和第二像素p2出射的光线经同一个透镜结构120汇聚。其中，第一像素p1发出的光线经透镜结构120汇聚于第一视点，第二像素p2发出的光线经透镜结构120汇聚于第二视点。
人眼的瞳孔在水平方向的活动范围通常为2毫米至8毫米，为了使单眼能够看到三维效果，需要使第一视点和第二视点的间距位于瞳孔的活动范围内。这也就是说，第一视点和第二视点的间距大于或等于2毫米且小于或等于8毫米。
在本实施例中，第一像素p1和第二像素p2发出的光线略有差异，从而使第一视点和第二视点观看到的图像略有差异，经由视差产生三维效果。
在本申请的显示装置中，如图1和图2所示，显示屏11包括多个第三像素p3和多个第四像素p4，一个透镜结构120至少对应于一个第三像素p3和一个第四像素p4，第三像素p3发出的光线经透镜结构120汇聚于第三视点，第四像素p4发出的光线经透镜结构120汇聚于第四视点，第三视点和第四视点间隔设置；其中，第三视点和第四视点的间距大于或等于2毫米且小于或等于8毫米，第一视点、第二视点中的任一者与第三视点、第四视点中的任一者的间距大于8毫米。
在本实施例中，显示屏11还包括第三像素p3和第四像素p4，一个透镜结构120至少对应于一个第三像素p3和一个第四像素p4。即一个透镜结构120至少在显示屏11的显示面上的正投影至少覆盖一个第三像素p3和一个第四像素p4，第三像素p3和第四像素p4出射的光线经同一个透镜结构120汇聚。
类似地，第三视点、第四视点的间距大于或等于2毫米且小于或等于8毫米，从而使单眼能够看到第三视点和第四视点，进而能够看到三维效果。
第一视点、第二视点中的任一者与第三视点、第四视点中的任一者的间距大于8毫米。这也就是说，第一视点、第二视点中的任一者与第三视点的间距大于8毫米，且第一视点、第二视点中的任一者与第四视点的间距大于8毫米。
通过上述设置，可以使第一视点、第二视点被同一只眼睛观察到，使第三视点、第四视点被另一只眼睛观察到，从而使不同观察视角上观察到图像，提升三维场景的视角连续性。
在本申请的显示装置中，如图2和图4所示，显示装置还包括主透镜13，主透镜13设置于微透镜阵列12背离显示屏11的一侧；其中，微透镜阵列12使显示屏11的图像形成第一实像v1，主透镜13位于第一实像v1背离微透镜阵列12的一侧，且第一实像v1与主透镜13的间距为第二间距g2，第二间距g2大于零且小于主透镜的焦距f2。
在本实施例中，显示装置可以为VR（Virtual Reality，虚拟现实）显示设备。
在本实施例中，显示装置包括主透镜13，主透镜13设置于微透镜阵列12远离显示屏11的一侧。显示屏11的画面经微透镜阵列12汇聚后形成位于微透镜阵列12背离显示屏11一侧的第一实像v1。第一实像v1位于微透镜阵列12与主透镜13之间，且第一实像v1位于主透镜的焦距f2内。
第一实像v1与主透镜13的间距为第二间距g2，需要说明的是，第二间距g2是第一实像v1到主透镜13的光心的间距。由于第二间距g2大于零且小于主透镜的焦距f2，即0<g2<f2，第一实像v1经主透镜13汇聚后形成第二虚像v2。第二虚像v2位于显示屏11背离主透镜13一侧，第二虚像v2为最终成像。此时，第二虚像v2、显示屏11位于微透镜阵列12的同一侧，第一实像v1、主透镜13位于微透镜阵列12的另一侧。
图4示出了虚实结合模式。虚实结合模式是指经微透镜阵列12形成的为第一实像v1，第一实像v1经主透镜13形成第二虚像v2，第二虚像v2为最终成像。在虚实结合模式中，f1<g1<2*f1，0<g2<f2。
本实施例通过采用虚实结合模式，相较于双虚像模式，能够显著提升显示分辨率。这是因为，实像模式下的显示分辨率高于虚像模式下的显示分辨率。
下面结合图5和图6对此进行说明。如图5所示，图5中的（a）示出了实像模式，（b）示出了虚像模式；实像模式与虚像模式的其他条件一致，其区别在于（a）中显示屏11与微透镜阵列12的间距为g1，（b）中显示屏11与微透镜阵列12的间距为g1’。
在实像模式中，第一实像v1与显示屏11分别位于微透镜阵列12的两侧，且f1<g1<2*f1；其中，f1为透镜结构的焦距f1。
在虚像模式中，第一虚像v3与显示屏11位于微透镜阵列12的同一侧，且0<g1’<f1。其中，f1为透镜结构的焦距f1。
根据高斯成像公式和相似三角形公式结合，能够求出实像模式下第一实像v1的显示像素尺寸为x1=(L1-f1)u1/f1；在虚像模式下第一虚像v3的显示像素尺寸为x3=(L1’+f1)u1/f1。
其中，L1是第一实像v1与微透镜阵列12的间距，L1’是第一虚像v3与微透镜阵列12的间距，f1是透镜结构的焦距f1，u1是显示屏11的像素尺寸，由上述公式可得，第一虚像v3的像素尺寸x3大于第一实像v1的像素尺寸x1，因此第一虚像v3的分辨率较低。
如图6所示，图6为相关技术中的双虚像模式的显示原理说明图。双虚像模式是指经微透镜阵列12形成的为第一虚像v3，第一虚像v3经主透镜13形成第三虚像v4。第三虚像v4为最终成像。为便于比较说明，在图6中，显示屏11、微透镜阵列12、主透镜13与图4中的相同，其不同之处在于显示屏11与微透镜阵列12的间距为g1’、第一虚像v3与微透镜阵列12的间距L1’，也即g1’≠g1，L1’≠L1。在双虚像模式中，0<g1’<f1，0<g’2<f2。
由于第一虚像v3的像素尺寸x3大于第一实像v1的像素尺寸x1，因此，虚实结合模式的最终成像的像素尺寸小于双虚像模式的最终成像的像素尺寸，即虚实结合模式的分辨率大于双虚像模式的分辨率。
图7示出了本申请的实施例提供的显示装置的分辨率提升数据图。假设在双虚像模式和虚实结合模式下的透镜结构的焦距f1均为f1，主透镜的焦距f2均为f2，且g2=g2’。最终成像面位置相同，即第二虚像v2与主透镜13的间距L2等于第三虚像v4与主透镜13的间距L2’。在双虚像模式中0<g1’<f1,0<g2’<f2；在虚实结合模式中，f1<g1<2*f1，0<g2<f2。
例如，当f1=5毫米，f2=65毫米，g2=g2’=61毫米，L2=L2’=1000毫米时，设g1分别设计为3.8毫米至4.6毫米、g1’=6毫米。由计算可得，虚实结合模式方案相较双虚像模式方案在最终成像面之间的分辨率比值分别为1.9至5.6倍。
请参阅图7，横坐标为第一间距g1，纵坐标为虚实结合模式的最终成像的分辨率与双虚像模式的最终成像的分辨率的比值。虚实结合模式方案相较双虚像模式方案在最终成像面之间的分辨率比值分别为1.9至5.6倍。例如，当g1为4.2毫米时，虚实结合模式方案相较双虚像模式方案在最终成像面之间的分辨率比值为2.8倍，也即本申请的虚实结合模式可显示提升显示分辨率。
在本申请的显示装置中，透镜结构的焦距f1小于主透镜的焦距f2，第一间距g1小于第二间距g2。
在本实施例中，透镜结构120用于使显示屏11的画面形成三维显示，透镜结构的焦距f1范围为1毫米至20毫米。
在本实施例中，主透镜13用于使三维图像放大，主透镜的焦距f2范围为20毫米至100毫米。
需要说明的是，透镜结构的焦距f1、主透镜的焦距f2可以根据显示屏11的尺寸及观看者的位置进行调整，本申请对此不作限制。
在本申请的显示装置中，透镜结构120为条状凸透镜，多个条状凸透镜沿第一方向D1排布且沿第二方向D2延伸；其中，在第一方向D1上，条状凸透镜的短边的长度等于显示屏11中像素的宽度的整数倍。
在本实施例中，透镜结构120可以为条状凸透镜。条状凸透镜的长轴方向为第二方向D2，多个条状凸透镜沿第一方向D1排布。条状凸透镜在垂直于第二方向D2上的截面形状至少包括一段弧形。条状凸透镜可以为平凸透镜或双凸透镜。
通常，三维显示装置的水平方向需要设置多个视点，以提供不同的观看者观看，而在竖直方向上，视点的数量可以较小。因此，在部分实施例中，第一方向D1可以为水平方向，第二方向D2可以为竖直方向。从而实现水平方向上多个视点，满足多个观看者的观看需求。
在本实施例中，条状凸透镜在第一方向D1上的边长为短边。条状凸透镜的短边的长度等于显示屏11中像素的宽度的整数倍。像素的宽度是指像素在第一方向D1上的尺寸。通过上述设置，能够使多个像素经同一个条状凸透镜汇聚而成像，实现单眼可观看到三维效果。
可选地，在部分实施例中，第二方向D2与第一方向D1的夹角为90度。即第一方向D1与第二方向D2垂直。例如，第一方向D1可以为水平方向，第二方向D2可以为竖直方向，但不限于此。
可选地，在部分实施例中，第二方向D2与第一方向D1的夹角大于0度且小于90度。通过上述设置，可以改善显示屏11与微透镜阵列12产生的光学干涉，改善摩尔纹现象。
在本申请的显示装置中，透镜结构120为凸透镜，多个凸透镜至少沿两个方向排布，显示屏11包括多个像素，凸透镜与像素对位设置。
在本实施例中，透镜结构120为凸透镜，凸透镜至少沿两个方向排布。两个方向的夹角可以大于0度且小于或等于90度。凸透镜可以为块状凸透镜，多个凸透镜连接设置，从而可以简化凸透镜与显示屏11的组装工艺。
凸透镜在显示屏11的显示面上的正投影可以为圆形、矩形、三角形、五边形等。本申请对凸透镜的形状不作限定。凸透镜与像素对位设置，这也就是说，凸透镜在显示屏11上的正投影与像素对位，至少一个像素位于凸透镜在显示屏11上的正投影内。
应当理解的是，凸透镜的形状可以根据像素的形状适应性地设置，从而使凸透镜与像素对位设置。
在本申请还提供一种显示终端，显示终端包括上述的显示装置。
在本实施例中，显示终端可以为：手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪、VR设备等任何具有显示功能的产品或部件。
在上述实施例中，对各个实施例的描述都各有侧重，某个实施例中没有详述的部分，可以参见其他实施例的相关描述。
