具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附图，对本公开实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本公开保护的范围。
除非另外定义，本公开使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。
在研究中，本申请的发明人发现：将通常的显示面板应用于集成成像显示技术时，显示面板上往往有大量的像素处于关闭状态，造成显示面板的像素利用率低。并且，由于通常的显示面板上的像素均匀排布，很难再增加显示面板 的分辨率或PPI(Pixel Per Inch)。
本公开实施例提供一种显示面板和显示装置。该显示面板包括多个像素岛区域，各像素岛区域包括至少两个像素单元的有效显示区，各像素岛区域中相邻的像素单元之间的距离小于相邻的像素岛区域之间的距离。也就是说，该显示面板将多个像素单元的有效显示区设置在多个像素岛区域中，并且各像素岛区域包括至少两个像素单元的有效显示区；当该显示面板用于集成成像显示技术时，多个像素岛区域可用于显示，而像素岛区域之间的区域不用于显示，不设置像素单元的有效显示区，从而可提高该显示面板的像素利用率。另外，由于像素岛区域之间的区域不设置像素单元的有效显示区，可将像素单元的一些驱动元件设置在此区域中，从而可降低设置在各像素岛区域中的像素单元的面积，从而可在像素岛区域中设置更多的像素单元的有效显示区，从而可提高各像素岛区域的分辨率或PPI。
下面，结合附图对本公开实施例提供的显示面板和显示装置进行详细的说明。
本公开一实施例提供一种显示面板。图1为根据本公开一实施例提供的显示面板的平面示意图。如图1所示，该显示面板包括多个像素岛区域120，各像素岛区域120包括至少两个像素单元110的有效显示区112，各像素岛区域120中相邻的像素单元110之间的距离小于相邻的像素岛区域120之间的距离。需要说明的是，上述的有效显示区是指像素单元可发光或透光并进行显示的区域。
在本实施例提供的显示面板中，显示面板的像素单元的有效显示区被分布于显示面板的多个像素岛区域，像素岛区域之间可不设置像素单元或者不设置像素单元的有效显示区。当该显示面板用于集成成像显示技术时，多个像素岛区域可对应微透镜阵列或者针孔阵列设置，此时，多个像素岛区域可用于显示，而像素岛区域之间的区域不用于显示并且不设置像素单元或者不设置像素单元的有效显示区，从而可在实现集成成像的同时，提高该显示面板的像素利用率，例如，该显示面板的像素利用率可达100％。另外，由于像素岛区域之间的区域不设置像素单元，并且各像素岛区域可仅包括至少两个像素单元的有效显示区，可将像素单元的一些驱动元件(例如薄膜晶体管)设置在像素岛区域之间，而不设置在像素岛区域中，从而可在像素岛区域中设置更多的像素单元的有效显示区，从而可提高各像素岛区域的分辨率或PPI。
需要说明的是，在本实施例提供的显示面板中，各像素岛区域包括至少两个像素单元的有效显示区，各像素岛区域内的至少两个像素单元的有效显示区可分别发出不同视点的光。例如，各像素岛区域包括两个像素单元的有效显示区；对于各像素岛区域，两个像素单元的有效显示区中的一个像素单元的有效显示区可发出第一视点的光，并通过微透镜或针孔的投射被左眼接收，另一个像素单元的有效显示区可发出第二视点的光，并通过微透镜或针孔的投射被右眼接收，通过对像素进行特定的图像渲染，从而可实现3D显示。值得注意的是，上述的“不同视点的光”可指同一物体上同一点在不同视点下的像素点，或者同一物体上不同点在不同视点下的像素点。
例如，如图1所示，在各像素岛区域120中，相邻的像素单元110之间的距离为D1；在该显示面板中，相邻的像素岛区域120之间的距离为D2；如图1所示，D2大于D1。例如，在一些示例中，D2大于D1的n倍，其中，n大于等于3。
例如，在一些示例中，如图1所示，多个像素岛区域120可非均匀设置。当该显示面板用于集成成像时，多个像素岛区域与微透镜阵列中的多个微透镜或针孔阵列中的多个针孔一一对应设置，各像素岛区域发出的光需要通过对应设置的微透镜或针孔投射到人眼观察范围里，因此位于显示面板不同位置的各像素岛区域与对应设置的微透镜或针孔的相对位置关系不同，因此，多个像素岛区域非均匀设置。例如，当人眼观察范围在显示面板的正投影位于显示面板的中间区域时，位于显示面板各边缘的像素岛区域需要偏离对应设置的微透镜或针孔的中心以保证其发出的光可投射到人眼观察范围中。需要说明的是，显示面板上各像素岛区域的具体位置可根据显示面板的尺寸和人员观察范围的位置和大小进行设置。
图2为根据本公开一实施例提供的显示面板的局部示意图。如图2所示，该显示面板还包括围绕多个像素岛区域120设置的间隔区域130；间隔区域130为非显示区域，也就是说，间隔区域130不设置像素单元110或者不设置像素单元110的有效显示区112，不进行发光或透光显示。相对于通常的显示面板，当本实施例提供的显示面板用于集成成像时，间隔区域内不设置像素单元的有效显示区，一方面可提高像素单元的利用率，另一方面可节省材料和成本。
例如，在一些示例中，各像素单元还包括液晶层或有机发光层。也就是说，该显示面板的类型可为液晶显示面板或有机发光二极管显示面板。
例如，在一些示例中，如图2所示，各像素单元110可包括驱动元件114；驱动元件114可位于间隔区域130中，也就是说，驱动元件114可设置在像素岛区域120之外。由此，可在像素岛区域中设置更多的像素单元的有效显示区，从而可提高各像素岛区域的分辨率或PPI。
例如，在一些示例中，如图2所示，各驱动元件114可通过导线116与对应的像素单元110的有效显示区112相连。
例如，当该显示面板的类型为液晶显示面板时，驱动元件114可包括薄膜晶体管，用于控制像素单元的开关；然而，由于薄膜晶体管通常为不透明的，需要在薄膜晶体管上设置黑矩阵，此时该驱动元件所对应的区域就不能用于透光显示。通过将驱动元件114设置在间隔区域130中，可在各像素岛区域120仅设置像素单元110的有效显示区112，从而可在同样面积的像素岛区域中设置更多的像素单元110的有效显示区112，进而可提高各像素岛区域的分辨率或PPI。
例如，在该显示面板的类型为有机发光二极管显示面板时，驱动元件114可包括各种用于驱动有机发光二极管像素单元发光的薄膜晶体管和电容等元件。同样地，通过将驱动元件114设置在间隔区域130中，可在各像素岛区域120仅设置像素单元110的有效显示区112，从而可在同样面积的像素岛区域中设置更多的像素单元110的有效显示区112，进而可提高各像素岛区域的分辨率或PPI。值得注意的是，由于有机发光二极管显示面板的驱动元件所占的面积较大，因此当在该显示面板的类型为有机发光二极管显示面板时，通过将驱动元件设置在间隔区域提升的分辨率或PPI较大。
需要说明的是，本公开实施例提供的显示面板的类型并不限于上面描述的液晶显示面板和有机发光二极管显示面板，还可为其他类型的显示面板，例如：电子纸显示面板。另外，当将驱动元件设置在间隔区域时，各像素岛区域中除了各像素单元的有效显示区之外，还可设置的必要的像素限定结构，例如像素限定层或用于像素限定的黑矩阵(不包括遮挡驱动元件的黑矩阵)。
例如，在一些示例中，如图1和图2所示，各像素岛区域120设置至少三个像素单元110的有效显示区112，各像素岛区域120内的像素单元110的有效显示区112阵列排布。由此，各像素岛区域可分别发出至少三种视点的光，从而可实现光场显示。另外，当该显示面板用于集成成像显示装置时，由于各像素岛区域的分辨率或PPI的提高，各像素岛区域可设置更多的像素单元的有 效显示区，从而使得该显示面板可提供更多的视点的光，从而可提高采用该显示面板的集成成像显示装置的可视范围。
例如，在一些示例中，各像素岛区域内的像素单元的有效显示区可分别发出不同视点的光。例如，当各像素岛区域包括三个像素单元的有效显示区；对于各像素岛区域，三个像素单元的有效显示区中的一个像素单元的有效显示区可发出第一视点的光，并通过微透镜或针孔的投射被左眼接收，另一个像素单元的有效显示区可发出第二视点的光，并通过微透镜或针孔的投射被右眼接收，从而可实现3D显示；此外，另一个像素单元的有效显示区可发出第三视点的光，可在用户的眼睛发生移动时，通过微透镜或针孔的投射被左眼或右眼接收，从而提供更多的视点的光。
本公开一实施例还提供一种显示装置。图3为根据本公开一实施例提供的一种显示装置的示意图。如图3所示，该显示装置包括显示面板100，该显示面板100可采用上述的任一显示面板。
在本实施例提供的显示装置中，显示面板的像素单元被分布于显示面板的多个像素岛区域，像素岛区域之间可不设置像素单元或者不设置像素单元的有效显示区。当该显示装置用于集成成像显示技术时，多个像素岛区域可对应微透镜阵列或者针孔阵列设置，此时，多个像素岛区域可用于显示，而像素岛区域之间的区域不用于显示并且不设置像素单元或者不设置像素单元的有效显示区，从而在实现集成成像的同时，提高该显示面板的像素利用率。另外，由于像素岛区域之间的区域不设置像素单元，并且各像素岛区域可仅包括至少两个像素单元的有效显示区，可将像素单元的一些驱动元件(例如薄膜晶体管)设置在像素岛区域之间，而不设置在像素岛区域中，从而可在像素岛区域中设置更多的像素单元的有效显示区，从而可提高各像素岛区域的分辨率或PPI。
例如，在一些示例中，如图3所示，该显示装置还包括微透镜阵列210，包括多个微透镜212；多个微透镜212与多个像素岛区域120一一对应设置，各微透镜212可将各对应设置的像素岛区域120发出的光投射至人眼观测范围500。
例如，如图3所示，各像素岛区域120包括至少三个像素单元110的有效显示区112；各像素岛区域120内的至少三个像素单元110的有效显示区112可分别发出不同视点的光。以各像素岛区域120包括三个像素单元110的有效显示区112为例，对于各像素岛区域120，三个像素单元110的有效显示区112 中的一个像素单元110的有效显示区112可发出第一视点的光，并通过对应设置的微透镜212的投射被左眼410接收，另一个像素单元110的有效显示区112可发出第二视点的光，并通过对应设置的微透镜212的投射被右眼420接收，从而可实现3D显示；此外，另一个像素单元110的有效显示区112可发出第三视点的光，可在用户的眼睛发生移动时，通过对应设置的微透镜212的投射被左眼或右眼接收，从而提供更多的视点的光。
例如，在一些示例中，各微透镜可使各对应设置的像素岛区域的至少两个像素单元的有效显示区发出的光投射到不同视点。也就是说，当各像素岛区域内的至少二个像素单元的有效显示区分别发出不同视点的光时，各微透镜可使各对应设置的像素岛区域的至少两个像素单元的有效显示区发出的光投射到不同视点。由此，可使得各像素岛区域内的至少二个像素单元的有效显示区分别发出不同视点的光被投射到不同视点。
例如，在一些示例中，微透镜阵列可使多个像素岛区域的至少两个像素单元的有效显示区发出光聚焦在人眼观察范围的至少两个视点。
例如，在一些示例中，如图3所示，各像素岛区域120设置的至少两个像素单元110的有效显示区112包括第一像素单元有效显示区1121、第二像素单元有效显示区1122和第三像素单元有效显示区1123，微透镜阵列210可将多个像素岛区域120设置的第一像素单元有效显示区1121发出的光聚焦在人眼观察范围500的第一视点510，第二像素单元有效显示区1122发出的光聚焦在人眼观察范围500的第二视点520，第三像素单元有效显示区1123发出的光聚焦在人眼观察范围500的第三视点530。
例如，如图3所示，多个像素岛区域120在显示面板的显示面内可非均匀设置。由于各像素岛区域发出的光需要通过对应设置的微透镜或针孔投射到人眼观察范围500里，因此位于显示面板100不同位置的各像素岛区域120与对应设置的微透镜212的相对位置关系不同，因此，多个像素岛区域120非均匀设置。例如，如图3所示，人眼观察范围500在显示面板100的正投影位于显示面板100的中间区域时，位于显示面板100边缘的像素岛区域120需要偏离对应设置的微透镜212的中心以保证其发出的光可投射到人眼观察范围500中。图4为根据本公开一实施例提供一种像素岛区域和人眼观察范围的几何光学关系示意图。如图4所示，当人眼观察范围500位于显示装置一个微透镜212的中心轴的上侧，且人眼观察范围500的边缘距离该微透镜212的中心轴的距 离为H时，与该微透镜212对应设置的像素岛区域120需要偏离对应设置的微透镜212的中心轴h，以保证其发出的光可投射到人眼观察范围500中。并且，当像素岛区域120与微透镜212的距离为d，人眼观察范围500与微透镜212的距离为D时，h的大小可根据下列公式算出：

图6为根据本公开一实施例提供的另一种显示装置的像素岛区域和微透镜阵列的位置关系示意图。如图6所示，微透镜212可为矩形微透镜，矩形微透镜212密集排列以形成微透镜阵列210。多个微透镜212与像素岛区域120一一对应设置；并且，像素岛区域120非均匀设置。另外，如图6所示，矩形微透镜212的轮廓215并不构成对与其对应设置的像素岛区域120的限制，也就是说，像素岛区域120并不一定要设置在对应设置的矩形微透镜212的轮廓215所围成的区域内，只要像素岛区域120发出的光可通过对应设置的矩形微透镜212投射到人眼观察范围即可。
