具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性 劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明的说明书和权利要求书及所述附图中的术语“第一”、“第二”等是用于区别不同对象，而不是用于描述特定顺序。此外，术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。
在本文中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本发明的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本文所描述的实施例可以与其它实施例相结合。
请参阅图1和图2，本发明第一实施例提供一种显示面板10，显示面板10包括集光器件100和光传感器200，集光器件100包括相对设置的第一表面110和第二表面120、以及连接第一表面110和第二表面120的第三表面130，至少部分外界光线L自第一表面110入射进集光器件100内部，并从集光器件100内部入射至第三表面130且被第三表面130反射后经由第二表面120出射至光传感器200。
其中，第一表面110为外界光线自显示面板10入射后到达集光器件100的表面，一般来说外界光线自第一表面110入射后，经过集光器件100内部到达与第一表面110相对设置的第二表面120，并经过第二表面120出射，入射到光传感器200。在本发明实施例中，在第一表面110和第二表面120之间设置第三表面130，可以使得不直接入射到第二表面120上的至少部分外界光线入射到第三表面130，且至少部分外界光线入射到第三表面130后被第三表面130反射，而反射后的外界光线再经由第二表面120出射至光传感器200。也就是说经过第三表面130反射的外界光线再次入射到光传感器200中。优选地，外界光线被第三表面130全反射后经由第二表面120出射至光传感器200。如果外界光线被第三表面130全反射，则全部光线从第三表面130出射，会进一步增加入射到光传感器200中的光线强度。
可以理解的是，显示面板10包括其他的膜层，例如覆盖层、触控层、显示功能层或者基底等，在图1中为了说明集光器件100和光传感器200设置在显示面板10中，而将集光器件100和光传感器200设置在基底800的下方，在其他实施例中集光器件100和光传感器200还可设置在其他膜层之间(请参阅图11至图16)。
本发明提供的显示面板10通过集光器件100中的第三表面130对至少部分外界光线全反射，可以提高入射到光传感器200的光线强度，进而提升光传 感器200的光线灵敏度。
可以为任意一种显示面板10中需要接收外界光线的器件，包括但不限于用于光学指纹识别、环境光感测、距离监测等功能的光传感器。所述显示面板10可以为液晶显示面板、有机电致发光显示面板或者柔性显示面板。
需要说明的是，集光器件100的结构形状不做限定，或者说第一表面110和第二表面120之间的高度、第三表面130与第二表面120之间的夹角、以及第二表面120的大小、集光器件100的材料等不做限定，只要能够实现至少部分外界光线入射到第三表面130后，被第三表面130全反射后经由第二表面120出射至光传感器200即可。请参阅图3中a图和b图，图3中示出其中两种结构以及光路图，本发明中的集光器件100的结构不限于图3中的两种。
请再次参阅图2，在进一步的实施例中，第一表面110的面积大于第二表面120的面积。第一表面110为外界光线入射到集光器件100的表面，将第一表面110的面积设置大于第二表面120的面积，可以增加入射第一表面110的外界光线。
优选的，第一表面110为平面，第二表面120为平面，如图2所示。当第一表面110和第二表面120均为平面时，且第一表面110的面积大于第二表面120的面积时，第三表面130与第二表面120之间具有一定的夹角。从图2中的光路图所示，外界光线L入射到第一表面110后，部分外界光线L1垂直入射到集光器件100中，并直接达到第二表面120，然后经由第二表面120出射到光传感器200中；部分外界光线L2垂直入射到集光器件100中，达到第三表面130，然后经由第三表面130反射后经由第二表面120出射到光传感器200中。在本实施例中，外界光线至少可以从上述两种路径到达光传感器200，进而增加入射到光传感器200的外界光线。
在进一步的实施例中，光传感器200包括第四表面210，第四表面210的面积大于或等于第二表面120的面积，第二表面120贴合在第四表面210上。将第四表面210的面积设置大于或等于第二表面120的面积，使得自第二表面120出射的光线能够完全入射到第四表面210上而被光传感器200接收，如果第四表面210的面积小于第二表面120的面积，那么会有部分光线自第二表面120与第四表面210不重叠的区域出射而不能入射到第四表面210上，进而造成光线损失。将第二表面120贴合在第四表面210上，相较于第二表面120和第四表面210具有空隙的设置，可以降低界面反射，避免入射到第四表面210上的光线损失。
请参阅图4，本发明第二实施例提供一种显示面板10a，图4中仅示出了集光器件100和光传感器200，可以理解的是，在显示面板10a中还包括其他功能膜层。在本实施例中，集光器件100由具有预设折射率材料制成，以使外界光线与第一表面110的垂直线O1之间呈现第一预设角度β入射到集光器件 100内部时，进入到集光器件100内部的外界光线能被第三表面130全反射。
其中第一预设角度可以为一个具体的角度，也可以为一个角度范围。当集光器件100的预设折射率不同时，第一预设角度也会不同。优选的，采用能够使外界光线以最大范围的第一预设角度入射到集光器件100内部，并能被第三表面130全反射时所具有的预设折射率材料制成集光器件100。也就是说，在选择以何种材料制成集光器件100时，优先考虑选择能够保证外界光线可以以最大范围的第一预设角度入射到集光器件100内部并能被第三表面130全反射的材料，该材料所具有的折射率即为所述预设折射率。本实施例的上述设置，可以保证外界光线以最大入射角范围入射第一表面110，进而增加入射到第一表面110且能够被第三表面130全反射的外界光线。
在进一步的实施例中，第二表面120包括相对设置的第一边缘线121和第二边缘线122，第三表面130与第二表面120于第一边缘线121相交，第二边缘线122各位置与第一边缘线121各位置之间至少具有第一预设距离D，第三表面130与第二表面120之间具有第二预设角度θ，第一表面110和第二表面120之间具有第二预设距离H，以使自第三表面130入射的外界光线L被全反射后经由第二表面120出射至光传感器200。也就是说通过对上述条件的设置而使得外界光线L能够更多的被第三表面130全反射后经由第二表面120出射至光传感器200。具体通过下述实施例来说明。
请参阅图5，在本实施例中，集光器件100设为圆棱台形，即第一表面110和第二表面120为圆形，且第一表面110与第二表面120平行设置，其中第二表面120中的第一边缘线121和第二边缘线122首尾连接而形成圆形。在本实施例中，第三表面130即为第一表面110和第二表面120之间的表面，将第三表面130铺展时，第三表面130为扇面。图4中的集光器件100结构为图5中的集光器件100沿第一表面110直径的剖面图。
如图5所示，第一表面110与第三表面130相交于第三边缘线123，所述第三边缘线123包括边缘点A。当外界光线L从边缘点A入射到第一表面110上时，其实质也是入射到第三表面130的最上边缘的位置，下面以外界光线L入射到边缘点A为例来说明入射到边缘点A处且能被第三表面130全反射后经由第二表面120出射到光传感器200的外界光线L的入射角度范围。
设集光器件100的预设折射率为n，全反射的临界角为α，根据临界角计算公式：sinα＝1/n，即α＝arcsin 1/n。当n＝1.5时，计算得到α为41.8°。
设第一预设距离为D，第二预设距离为H，第一预设角度β，第二预设角度为θ。其中D、H的大小设置要求能够保证被第三表面130全反射的外界光线入射到第二表面120，并经由第二表面120入射到光传感器200中。
如图4所示，将第二表面120其中一点作延长线m，延长线m与第三表面130之间的夹角即为所述θ；在边缘点A处作第一表面110的垂直线O1，外界 光线L与垂直线O1的夹角即为所述β；在边缘点A处作第三表面130的垂直线O2，其中垂直线O2即为外界光线L从边缘点A处入射到第三表面130的法线O2，此时外界光线L与法线O2之间的夹角设为γ，即外界光线L能够在第三表面130全反射时，γ的大小为：α≤γ≤90°。
由于第一表面110与第二表面120平行，所以第一表面110与第三表面130之间的夹角为θ，得到垂直线O1和法线O2之间的夹角为θ，即γ＝β+θ，即，α≤β+θ≤90°，进而得到，α-θ≤β≤90°-θ。
当n＝1.5时，α＝arcsin 1/n＝41.8°时，γ的大小为：41.8°≤γ≤90°，其中γ＝β+θ，即，41.8°≤β+θ≤90°，即41.8°-θ≤β≤90°-θ，也就是说，当第一预设角度β满足上述条件时，能够保证自边缘点A处入射的外界光线L被第三表面130全反射。
在本实施例中设θ＝30°，此时11.8°≤β≤60°，也就是说，当外界光线L以第一预设角度β在11.8°和60°之间入射到边缘点A时能够被第三表面130全反射。
需要说明的是，在上述具体实施例中，第一预设距离D和第二预设距离H的大小不做限定，只要满足，在第二预设角度为θ时，在上述第一预设角度β的范围内自边缘点A入射的外界光线L在第三表面130被全反射后能够入射到第二表面120，并经由第二表面120出射后入射到光传感器200即可。第一预设距离D和第二预设距离H的大小可根据实际产品需要来设置。
还需要说明的是，在上述具体实施例中，仅以边缘点A来说明外界光线L入射第三表面130并被第三表面130全反射的第一预设角范围。当外界光线从第一表面110的其他位置入射时，同样可根据实际需求来设置集光器件100的各参数，以达到外界光线以不同于或者相同于上述实施例中的第一预设角范围入射到第一表面110后，并能被第三表面130全反射的目的。
在其他实施例中，当集光器件100的预设折射率n不同时，全反射的临界角α也会不同，那么入射到第一表面110上的外界光线L能够被第三表面130全反射的第一预设角度β的范围也不同。集光器件100的预设折射率n可根据实际需要来设置。
在其他实施例中，第一表面110和第二表面120还可以为椭圆形、三角形或者多边形中的一种。
请参阅图6，本发明第三实施例提供一种显示面板10b，在本实施例中，集光器件100的第一表面110上设有增透膜140。增透膜140能够减少外界光线L在第一表面110的反射，增加入射到集光器件200的外界光线，进而提高入射到光传感器200上的光线强度。可以理解的是，在显示面板10b中还包括其他功能膜层，图6中仅示出集光器件100和光传感器200以说明。
请参阅图7，本发明第四实施例提供一种显示面板10c。在本实施例中， 第一表面110上设有多个微结构150，微结构150包括背朝第一表面110的第五表面151，第五表面151为弧面，弧面的曲率中心朝向第一表面110。在第一表面110上设置上述结构的微结构150，可以增加入射到集光器件100的光线入射范围，从而增加到达第一表面110的外界光线。可以理解的是，在显示面板10c中还包括其他功能膜层，图7中仅示出集光器件100和光传感器200以说明。
在进一步的实施例中，微结构150的反射率小于集光器件100的反射率。该设置进一步增加入射到集光器件100的外界光线。
请参阅图8，本发明第五实施例提供一种显示面板10d，在本实施例中，显示面板10d还包括反射板300，反射板300设置在集光器件100的周围，以用于将自集光器件100出射而没有入射到光传感器200的外界光线反射回集光器件100。
其中自集光器件100出射而没有入射到光传感器200的外界光线包括入射到集光器件100中的外界光线入射到第三表面130而没有被第三表面130全反射，进而自第三表面130出射的部分外界光线；还包括入射到第三表面130被全反射后但不能经由第二表面120入射到光传感器200，而从集光器件100中出射的外界光线。
通过增加反射板300，可降低外界光线损失，进一步提高入射到集光器件100中的外界光线利用率，使得外界光线能够更多的入射到光传感器200中。
可以理解的是，在显示面板10d中还包括其他功能膜层，图8中仅示出集光器件100、光传感器200以及反射板300以说明。在图8中仅示出了其中一种反射板300与集光器件100的位置结构关系，在其他实施例中，反射板300的结构可根据集光器件100的结构和产品需要来设置。
请参阅图9，本发明第六实施例提供一种显示面板10e，在显示面板10e中还包括显示功能层400，显示功能层400设置在集光器件100远离光传感器200的一侧，外界光线L自显示功能层400入射到集光器件100上，显示功能层400包括间隔设置的发光单元410，集光器件100与发光单元410在显示功能层400上的正投影至少部分不重叠。
其中显示功能层400为显示面板10e中用于发光的一层，发光单元410至少为一个像素大小。当发光单元410发出的光自显示功能层400向外出射时，其会干扰外界光线入射到集光器件100上，另外，发光单元410也会阻挡外界光线L从显示面板10e表面入射到集光器件100的传播路径。在本实施例中，将集光器件100与发光单元410至少部分错开设置，可以使得外界光线L能够自发光单元410之间的缝隙中入射到集光器件100上。
优选的，将集光器件100和光传感器200做成微米级的大小，而将集光器件100与发光单元410在显示功能层400上的正投影完全不重叠，以进一步降低发 光单元410出射的光线对集光器件100接收外界光线的干扰。
请参阅图10，在进一步的实施例中，发光单元410至少包括一个子发光单元411，集光器件100与子发光单元411在显示功能层400上的正投影至少部分不重叠。
其中子发光单元411是指至少为一个子像素大小，例如红色子发光单元、绿色子发光单元或者蓝色子发光单元，也就是说，集光器件100与上述子像素大小的子发光单元411至少部分错开设置，可以使得外界光线能够自子发光单元411之间的缝隙中入射到集光器件100上，进一步降低发光单元410出射的光线对集光器件100接收外界光线的干扰，以及避免发光单元410阻挡外界光线L从显示面板10e表面入射到集光器件100的传播路径的问题。
优选的，当发光单元410包括至少两个子发光单元411时，将集光器件100的大小设置为小于等于子发光单元411之间的间隙大小，以使集光器件100与子发光单元411在显示功能层400上的正投影完全不重叠。当发光单元410仅包括一个子发光单元411时，将集光器件100的大小设置为小于等于相邻两个发光单元410中的子发光单元411之间的间隙大小，以使集光器件100与相邻两个发光单元410中的子发光单元411在显示功能层400上的正投影完全不重叠。
请参阅图11，本发明第七实施例提供一种显示面板10f，在显示面板10f中还还包括覆盖层500、触控层600、偏光片700、显示功能层400以及基底800，显示功能层400设置在基底800的一侧，偏光片700设置在显示功能层400远离基底800的一侧，触控层600设置在偏光片700远离显示功能层400的一侧，覆盖层500设置在触控层600远离偏光片700的一侧，外界光线自覆盖层500入射到显示面板10f中的集光器件100上。其中偏光片700用于将显示功能层400出射的光线进行滤光，触控层600用于实现显示面板10f的触控感应功能，覆盖层500用于封装位于其下方的膜层以保护下方的膜层。
在本实施例中，集光器件100设置在基底800远离显示功能层400的一侧，光传感器200设置在集光器件100远离基底800的表面上。
请参阅图12，本发明第八实施例提供一种显示面板10g，与第七实施例不同的是，在本实施例中，集光器件100和光传感器200设置在显示功能层400与基底800之间，且光传感器200相较于集光器件100邻近基底800设置。
请参阅图13，本发明第九实施例提供一种显示面板10h，与第七实施例不同的是，在本实施例中，集光器件100和光传感器200设置在偏光片700与显示功能层400之间，且光传感器200相较于集光器件100邻近显示功能层400设置。
请参阅图14，本发明第十实施例提供一种显示面板10i，与第七实施例不同的是，在本实施例中，集光器件100和光传感器200设置在触控层600与偏光片700之间，且光传感器200相较于集光器件100邻近偏光片700设置。
请参阅图15，本发明第十一实施例提供一种显示面板10j，与第七实施例不同的是，在本实施例中，集光器件100和光传感器200设置在覆盖层500与触控层600之间，且光传感器200相较于集光器件100邻近触控层600设置。
请参阅图16，本发明第十二实施例提供一种显示面板10k，在显示面板10k中还包括设置有集光器件100和光传感器200的集光层900，集光层900包括与集光器件100和光传感器200相邻设置的平坦层1000。
其中平坦层1000的上表面与集光器件100的第一表面110相平齐，平坦层1000的下表面与光传感器200中与第四表面210背离的表面相平齐，而使集光层900的上下表面平整。
当将集光器件100和光传感器200设置在显示面板中的任意两层之间时，由于集光器件100和光传感器200具有一定的厚度，其会造成与之相邻的上下两层之间具有段差，而导致显示面板不平整，在本实施例中，将集光器件100和光传感器200所在的层，并与之相邻的位置设置平坦层900，使集光器件100和光传感器200所在的层平坦，避免段差。在图16中示出了集光器件100和光传感器200设置在覆盖层500与触控层600之间。
另外，请参考图17，本发明第十三实施例提供一种显示面板10l，与第七实施例不同的是，在本实施例中，集光器件100和光传感器200的数量为多个。本实施例以集光器件100和光传感器200的数量为三个进行示例。在本实施例中，集光器件100设置在基底800远离显示功能层400的一侧，光传感器200设置在集光器件100远离基底800的表面上。相邻的两个集光器件100和光传感器200之间为间隔设置。多个集光器件100和光传感器200的设置，可进一步提高入射到光传感器200的光线强度，进而提升光传感器的200光线灵敏度。
请参阅图18，本发明还提供一种电子装置20，电子装置20包括如上述任一实施例的显示面板10。其中电子装置20可以为但不仅限于为电子书、智能手机(如Android手机、iOS手机、Windows Phone手机等)、平板电脑、柔性掌上电脑、柔性笔记本电脑、移动互联网设备(MID，Mobile Internet Devices)或穿戴式设备等，或者可以为有机电致发光二极管(Organic light-emitting diodes，OLED)电子装置、有源矩阵有机发光二极管(Active Matrix Organic Light Emitting Diode，AMOLED)电子装置。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对本发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
