Description

显示屏、显示组件及电子设备 技术领域
本申请属于显示领域，具体涉及一种显示屏、显示组件及电子设备。
背景技术
3D结构光人脸解锁技术是目前应用在手机上解锁的主流方式之一。利用的是光斑的形变来识别目标物体的3D信息，进而实现解锁。
结构光的硬件组成是由IR camera和红外投射器组成，红外光斑经过投射器发出后，到达目标物体的表面，IR camera会拍摄形成的光斑图。
随着手机技术的发展，人们对于全屏手机的需求逐渐增加。目前的显示屏由于红外投射器发出的红外光无法透射OLED屏形成有效的光斑图，所以只能将红外投射器裸露安装在屏幕上，而当红外投射器设在屏幕上时，则无法实现全面屏手机，因此，严重影响了3D解锁的市场应用前景。
申请内容
有鉴于此，有必要提供一种显示屏，其可以实现全屏显示，同时还集成了显示和触摸功能。

其中，所述间隔支撑层的厚度大于投射至所述显示屏的光的波长。
其中，所述间隔支撑层的厚度为0.01mm-1mm。当间隔支撑层的厚度小于投射光的波长时，会使得光线不能很好的透过第一显示层。当间隔支撑层的厚度过大时，则使得显示屏的厚度过厚，会增加使用该显示屏的电子设备的厚度。
其中，所述透光点的尺寸小于投射至所述第一显示层的投射光的波长。
其中，所述透光点的尺寸小于940nm。当透光点尺寸大于投射至第一显示层的投射光的波长时，则会影响衍射的发生，使得光不能很好的穿过第一显示层并投射到触摸感应层上。
其中，所述透光点按照随机散斑分布，当投射光透过所述第一显示层后，形成散斑图案。形成散斑可以增加显示屏的透过率，提高能量利用率。

其中，所述显示屏还包括触摸感应层；
所述第二显示区为单独的一层；所述第一显示层、第二显示区及所述触摸 感应层依次层叠设置；
或者所述第二显示区与所述触摸感应层集成到同一层，所述第二显示区由显示补偿点组成，所述触摸感应层上与透光点相对应的位置设有孔洞，所述显示补偿点填充至所述孔洞中。

图4是本申请又一实施例的显示屏的结构示意图。

具体实施例
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，所描述的实施例是本申请的一部分实施例，而不是全部实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都应属于本申请保护的范围。
3D人脸识别目前主要有3D结构光和TOF(Time of Flight)两类技术。
结构光是一组由投影仪和摄像头组成的系统结构。用投影仪投射特定的光信息到物体表面后及背景后，由摄像头采集。根据物体造成的光信号的变化来计算物体的位置和深度等信息，进而复原整个三维空间。
TOF是飞行时间(Time of Flight)技术的缩写，即传感器发出经调制的近红外光，遇物体后反射，传感器通过计算光线发射和反射时间差或相位差，来换算被拍摄景物的距离，以产生深度信息，此外再结合传统的相机拍摄，就能将物体的三维轮廓以不同颜色代表不同距离的地形图方式呈现出来。
请参见图1和图2，本申请实施例提供的显示屏100包括第一显示层10、及第二显示区40。第一显示层10与第二显示区40间隔设置。第一显示层10上设有多个间隔的透光点11，光投射至第一显示层10后，能透过透光点11。第二显示区40包括多个显示补偿点41，显示补偿点41设在与透光点11相对应的位置，且每个显示补偿点41至少覆盖对应的透光点11；所述第一显示层10的显示区域的显示内容与第二显示区40的显示补偿点的显示内容相互配合，用于使所述显示屏100完整显示；所述第二显示区40显示补偿点41之外的区域可透光。当光从投射向显示屏100时，投射光会透射过第一显示层10上的透光点11，并发生衍射，到达第二显示区40后，从显示补偿点41的两侧射出。第二显示区40补偿了第一显示区10由于透光点10的存在导致的显示不完整，使得从用户角度看到的屏幕显示是完整的。在一些实施例中，第一显示层10为OLED层(Organic Light-Emitting Diode,OLED，有机发光二极管)，其上设有电路。第一显示层10的底部发光的每一个pixel(像素)是不透光的， pixels阵列组合在一起会阻挡相当一部分光进行透射。
在一些实施例中，透光点11为孔洞。在有机发光二极管制备完成后，再采用激光等技术进行打孔，形成第一显示区10。
在另一实施例中，透光点11由全透光材料形成，例如玻璃基板。具体地，在制备第一显示层10时，对在玻璃基板(图未示)上对要形成透光点11的区域覆盖掩膜，接着按照有机发光二极管的制备工序，在玻璃基板上涂覆或喷涂有机发光材料、电镀阳极、阴极等。可选择地，制备完整有机发光二极管后，对透光点11以外的区域进行掩膜，之后采用光刻等技术刻蚀，去除透光点11上的有机发光材料层，以形成第一显示层10。
在一些实施例中，透光点11的尺寸小于投射至第一显示层10的投射光的波长。更具体地，透光点11的尺寸小于940nm。当透光点11尺寸大于投射至第一显示层10的投射光的波长时，则会影响衍射的发生，使得光不能很好的穿过第一显示层10并投射到触摸感应层50上。
在一些实施例中，透光点11按照随机散斑分布。当透射光透射过第一显示层10后，透光点11的排布方式，使得投射光透过透光点11后形成散斑图案。形成散斑可以增加显示屏100的透过率，提高能量利用率。
在另一些实施例中，透光点11按照编码程序进行分布。当透射光透射过第一显示层10后，透光点11的排布方式，使得投射光透过透光点11后形成编码图案。形成编码图案，使得屏幕的显示效果更好，算法更简单。
请参见图3和图4，本申请的显示屏100还包括间隔支撑层30。间隔支撑层30位于第一显示层10和所述第二显示区40之间。间隔支撑层30可透光，用于支撑第二显示区40，并将所述第一显示层10及第二显示区40相间隔。在第一显示层10和第二显示区40之间增加间隔支撑层30，在第一显示层10和第二显示区40之间留出间隙，使的投射出第一显示层10的光线发生衍射。同时，还对第二显示区40起支撑作用，增加显示屏100各层的稳定性，提高显示屏100的耐用性。
在本实施例中，间隔支撑层30由化学钢化玻璃制得，间隔支撑层30是全透光的，对光线没有阻挡作用。
在一些实施例中，间隔支撑层30的厚度大于投射至显示屏100的光的波 长。可选地，间隔支撑层30的厚度为0.01mm-1mm。更具体地，间隔支撑层30的厚度为0.01mm、0.05mm、0.1mm、0.2mm、0.5mm、0.8mm或1mm。当间隔支撑层30的厚度小于投射光的波长时，会使得光线不能很好的透过第一显示层10。当间隔支撑层30的厚度过大时，则使得显示屏100的厚度过厚，会增加使用该显示屏100的电子设备的厚度。
请参见图5和图6，本申请的显示屏100还包括触摸感应层50。如图5所示，触摸感应层50与第二显示区40集成到同一层，第二显示区10由多个显示补偿点11组成，触摸感应层50上与透光点11相对应的位置设有孔洞51，所述显示补偿点11填充至所述孔洞51中。第一显示层10、间隔支撑层30及触摸感应层50依次层叠设置。或者如图6所示，触摸感应层50设置在第二显示区40与第一显示层10相对的一面，第一显示层10、间隔支撑层30、第二显示区40及触摸感应层50依次层叠设置。
请参见图6，在一些实施例中，第二显示区40为单独的一层，第二显示区40上设有显示补偿点41。第一显示层10、间隔支撑层30、第二显示区40及触摸感应层50依次层叠设置。显示补偿点41用于补偿第一显示层10上透光点11造成的显示不完整，第一显示层10与显示补偿点41配合，使得显示屏100的显示是完整的。在本实施例中，第二显示区40由全透光材料例如玻璃基板制备。显示补偿点41可以采用以下方式形成：在透光材料表面涂覆、喷涂或电镀有机发光二极管层后，在显示补偿点41区域覆盖光掩膜，采用光刻等技术进行刻蚀；或者对显示补偿点41以外的区域进行掩膜，在显示补偿点41区域形成与第一显示层10组成材料相同的显示补偿区域。
请参见图5，在一些实施例中，第二显示区40集成到触摸感应层50。第二显示区40由显示补偿点41组成，触摸感应层50上与透光点11相对应的位置设有孔洞51，显示补偿点41填充至孔洞51中。第一显示层10、间隔支撑层30及触摸感应层50依次层叠设置。将第二显示区40与触摸感应层50集成在一起，可以减小显示屏100的厚度。在一些实施例中，当第二显示区40与触摸感应层50独立的两层时，显示补偿点41的尺寸大于透光点11的尺寸。可选地，显示补偿点41的尺寸为透光点11尺寸的1-3倍。具体地，显示补偿点41的尺寸为0-3μm。更具体地，显示补偿点41的尺寸为0.01μm、0.1μ m、0.2μm、0.5μm、1μm、2μm或3μm。在本实施例中，显示补偿点41可以通过以下方式形成：在触摸感应层50上形成孔洞51，在孔洞51中通过涂覆或喷涂有机发光材料、电镀阳极、阴极等工艺形成显示补偿点41；或者在触摸感应层50表面涂覆、喷涂或电镀有机发光二极管层后，在显示补偿点41区域覆盖光掩膜，采用光刻等技术进行刻蚀去除非显示补偿点41的有机发光二极管材料。
当显示补偿点41的尺寸小于透光点11的尺寸时，则会影响显示屏100的显示功能；当显示补偿点41尺寸大于透光点11的尺寸过多时，则会影响光透过第二显示区40，进而影响显示效果。
在一些实施例中，当第二显示区40集成到触摸感应层50时，显示补偿点41的尺寸大于透光点11的尺寸。显示补偿点41用于补偿第一显示层10透光点11造成的显示不完整。可选地，显示补偿点41的尺寸为透光点11尺寸的1-3倍。具体地，显示补偿点41的尺寸为0-3μm。更具体地，显示补偿点41的尺寸为0.01μm、0.1μm、0.5μm、1μm、2μm、2.5μm或3μm。
当显示补偿点41的尺寸小于透光点11的尺寸时，则会影响显示屏100的显示功能；当显示补偿点41尺寸大于透光点11的尺寸很多时，则会影响触摸感应层50的触摸功能。
触摸感应层50用于实现显示屏100的触摸操作，其一般是完全透明的，对光没有阻挡作用。触摸感应层50的厚度为0.05-1mm。
当触摸感应层50的厚度过薄时，会增加加工的难度，同时会使触摸感应层的强度降低；当触摸感应层50的厚度过厚时，会增加显示屏100的厚度，不利于显示屏100的超薄化。
请参见图7，本申请还提供一种显示组件200，其投射器210及本申请的显示屏100。投射器210设置在第一显示层10的下方且与透光点11对应，投射器的出光口朝向第一显示层10。
请参见图8，本申请还提供一种电子设备300，其包括设备本体310、投射器210及本申请的显示屏100。显示屏100设置在设备本体310的表面，且触摸感应层50背对设备本体310设置。投射器210设置在设备本体310与显示屏100之间。
本申请的电子设备300包括但不限于手机、平板电脑、电脑、手环、手表、电子书阅读器、智能眼镜等具有显示屏的电子设备。
