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。
如图1所示,本发明实施例提供了一种显示面板,包括显示模组1,显示模组1中设有沿垂直于其出光面的方向贯穿的开孔11,遮光结构,所述遮光结构包括位于所述显示模组的开孔的内壁上的阻光层312。
上述显示面板中,显示模组的显示区设置有开孔,开孔沿垂直于显示模组的出光面的方向贯穿显示模组,用于安装摄像模组,摄像模组可以包括摄像头,摄像头可以安装在显示模组的开孔内,在显示模组的开孔内设置有遮光结构,遮光结构包括贴附在开孔内壁上的阻光层,阻光层贴附在显示模组的开孔内壁上,覆盖在开孔的内壁上,在产品点亮后,可以有效遮挡显示模组上的膜层在开孔处的漏光,进而避免产品点亮后摄像模组周侧边缘出现漏光问题,且结构简单可靠。
因此,上述显示面板中,在显示模组的开孔内壁上贴附有阻光层,在产品点亮后,阻光层可以有效遮挡显示模组上的膜层在开孔处的漏光,进而避免产品点亮后摄像模组周侧边缘出现漏光问题。
具体地,如图1和图2所示,上述显示面板还包括有盖板2,盖板2位于显示模组1的出光侧,例如,盖板可以为玻璃盖板;散热膜3,散热膜3设于显示模组1背离盖板2的一侧,散热膜3包括层叠设置的泡棉层31和金属层32,金属层32位于泡棉层31背离显示模组1的一侧,金属层32中具有与开孔11相对的第一通孔321,第一通孔321在盖板2上的垂直投影覆盖开孔11在盖板2上的垂直投影;所述泡棉层31包括位于所述显示模组与所述金属层之间的第一结构部311以及位于所述显示模组的开孔内壁的第二结构部312,所述第二结构部312构成阻光层。
上述显示面板中,在显示模组背离盖板的一侧设置有散热膜,散热膜包括层叠设置的泡棉层和金属层,金属层位于泡棉层背离显示面板的一侧,金属层中具有与显示面板上的开孔相对设置的第一通孔,第一通孔贯穿金属层,且第一通孔在垂直于显示模组的出光面上的正投影覆盖开孔在显示模组的出光面上的正投影,泡棉层的第一结构部位于金属层与显示模组之间,泡棉层的第二结构部与开孔对应,且可以第二结构部沿垂直于显示面的方向朝向开孔内弯折并贴附在显示模组的开孔内壁上,可以构成阻光层,第一结构部与第二结构部为一体式结构,泡棉层的一部分形成阻光层,其中,直接将泡棉层中层的一部分形成遮蔽开孔内壁的阻光层,结构可靠,制备简单,且直接以散热膜中与显示模组的开孔相对的部分形成阻光层遮挡开孔内壁,不会增加额外膜层结构,不会增加显示面板厚度。
具体地,泡棉层的材料为遮光材料,使泡棉层的第二结构部在开孔内壁上构成阻光层遮光性更好,更有利于避免开孔周侧漏光。
上述显示面板中还包括遮光层,所述遮光层21位于所述盖板2靠近所述显示模组1的一侧,所述遮光层21包括第二通孔211,所述开孔11在所述盖板的正投影覆盖所述第二通孔211在所述盖板的正投影。
为了再出光面的一侧对开孔边缘进行遮光,在盖板朝向显示模组的一侧设置遮光层,遮光层中具有与开孔相对设置的第二通孔,第二通孔与开孔相对可以使摄像模组实现采光摄像功能,遮光层可以在出光侧对开孔的边缘部分进行遮光,避免显示面板的出光面在开孔边缘漏光,其中,显示模组的开孔为圆形孔,所述开孔在垂直于所述显示模组的出光面的方向包括一对称轴,所述第一通孔设置为圆形,第二通孔也设置为圆形孔,所述第一通孔在垂直于所述显示面板的出光面方向的对称轴和所述第二通孔在垂直于所述显示面板的出光面方向的对称轴均与所述开孔的对称轴重合,即可以使该第二通孔的中心轴线以及第一通孔的中心轴线与显示模组的开孔的中心轴线重合设置,还可以设置第二通孔在垂直于盖板的正投影的面积小于开孔在盖板的正投影的面积,即可以设置第二通孔的直径B(如图1中所示)小于显示模组的开孔的直径,可以增强遮光严密性,在显示模组的出光面一侧更好的对摄像模组的周侧遮光。
结合图1参考图2所示,上述显示面板中,为避免金属层32中第一通孔321的边缘翘起,设置第一通孔321在盖板2上的垂直投影的直径大于开孔11在盖板2上的垂直投影的直径。其中,设置金属层中的第一通孔直径大于显示模组的开孔的直径,第二结构部向开孔内弯折会形成有与开孔边缘契合的弯折线316,即,金属层中第一通孔的直径大于泡棉层中第二结构部的弯折线的直径,金属层中第一通孔的边缘与泡棉层中第二结构部的弯折线之间具有一定的距离,金属层中第一通孔的边缘与泡棉层之间的贴合不会被泡棉层中的第二结构部的弯折处的变形影响,可以保证金属层与泡棉层之间贴合良好。
具体地,如图1所示,所述泡棉层还包括第三结构部313,所述第三结构部313包括第一端和第二端,所述第一端与所述第二结构部312靠近所述遮光层的一端连接,所述第二端与所述遮光层连接,例如可以为直接接触或通过其它层连接,在第二结构部312的自由端设置第三结构部313,第三结构部313将第二结构部312与遮光层衔接,有利于增强对显示模组内开孔周侧的遮光严密性。
具体地,所述第二结构部312完全覆盖所述开孔的内壁,所述第一结构部311、所述第二结构部312和所述第三结构部313为连续的一体结构。第二结构部312与第一结构部311为连续的一体结构,第二结构部312向开孔内弯折贴附在开孔内壁上,在开孔内壁上有微小的裂痕不会裸露开孔内壁太多,可以认为是第二结构部312可以将开孔内壁完全覆盖,第三结构部313可以为第二结构部312在自由端延伸至盖板2并搭接于盖板2的遮光层21上的一部分,结构性比较好,且第二结构部的自由端搭接在盖板上,且第二结构部312的自由端指向遮光层中的第二通孔的中心,第二结构部312的自由端的端部和盖板上的遮光层衔接上,连接紧密,保证遮光的严密性,具有更好的遮光效果,避免显示模组的开孔的边缘处漏光,且第二结构部的自由端延伸至盖板并与盖板连接,牢固性更好。
具体地,上述显示面板中,泡棉层31中与开孔对应的部分绕开孔中心轴线均匀分割开形成第二结构部312,第二结构部312均匀的贴附在开孔内壁上,对开孔内壁遮挡均匀,不会出现相邻的第二结构部312之间的间隙过大,遮光性更好。
上述显示面板中,第二结构部312和第三结构部313的长度尺寸根据显示模组沿垂直于出光面的方向的厚度尺寸A(如图1中所示)和第三结构部与盖板的搭接长度C(如图1中所示)的总和设置,使第三结构部的第二端可以搭接与盖板的遮光层上,且不伸入遮光层的第二通孔内,既保证遮光严密性,又不会影响摄像模组的摄像功能,其中,其中,第二结构部的长度可以设置和显示模组的厚度尺寸A相同,且由于第三结构部的结构特性,第三结构部不能完全在显示模组的开孔内壁与盖板之间的拐角处完全按照拐角的外形贴合,所以根据第三结构部与盖板的搭接长度C的长度,第三结构部设置长度时要留有贴合时的公差预留尺寸。
具体地,如图1所示,泡棉层31背离金属层32的一侧设有粘结层33,泡棉层31通过粘结层33粘结于显示模组1。粘结层可以为胶层,泡棉层通过胶层粘结在显示模组上,粘结方便简易,且稳固性好。
具体地,金属层可以为铜箔,所述金属层的材料也可以是铝、金或银,或者其它金属材料,本实施例不做局限。
本发明实施例还提供了一种显示装置,包括如上述实施例中提供的任意一种显示面板,所述显示面板包括显示模组以及设于所述显示模组的开孔中的摄像模组。
基于相同的发明构思,参考图1所示,本发明实施例还提供了一种显示面板的制备方法,显示面板的制备方法包括:
步骤S101,形成显示模组1,并在沿垂直于所述显示模组的出光面的方向形成贯穿的开孔11;
步骤S102,在显示模组1的开孔11内壁上形成阻光层312。
具体地,如图1和图2所示,上述制备方法中,在显示模组的开孔内壁上形成阻光层具体包括:
步骤S201,形成散热膜3,散热膜3包括层叠设置的泡棉层31和金属层32,金属层32上形成有第一通孔321,所述泡棉层包括第一结构部311和所述第二结构部312,所述第一结构部311位于所述显示模组与所述金属层之间,所述泡棉层中用于与所述开孔对应的部分形成绕所述第一通孔321的中心轴线分布且与所述第一通孔321的中心轴线垂直的多条切割线,以使形成绕所述第一通孔的中心轴线分布的第二结构部,其中,每条切割线的长度小于第一通孔的半径,切割线朝向第一通孔的一端不需要接触到第一通孔的边缘,且根据需要,当散热膜与显示模组对位贴合后,设置切割线的长度大于或等于开孔的半径,即设置切割线朝向第一通孔的一端与显示模组中的开孔边缘接触就可以,或者超过显示模组的开孔的边缘一些,可以增强第二结构部在弯折处与显示模组之间的贴附性,切割线可以根据产品具体结构需要设置;
步骤S202,将散热膜3贴附于显示模组1背离其出光面的一侧,金属层32的第一通孔321与显示模组的开孔11相对设置,具体地,使金属层32的第一通孔321的中心轴线与显示模组的开孔11的中心轴线重合设置,使泡棉层中的第二结构部朝向开孔的内壁弯折并贴附于开孔的内壁上,第二结构部312构成阻光层。
具体地,如图2所示,泡棉层31设有第三通孔315,第三通孔315与金属层32的第一通孔321同轴设置,第三通孔315与各切割线314连通,第三通孔315的直径小于显示模组的开孔11的直径,在泡棉层中与显示模组的开孔对应的部分的中心设置第三通孔,可以根据设置第三通孔的直径尺寸来控制泡棉层的第二结构部的长度,第三通孔的直径设置的较大些,第二结构部的长度就会相对小一些,避免第二结构部长度过长,避免贴附在开孔内壁上时自由端延伸至遮光层的第二开孔内,避免影响摄像模组采光。
具体地,上述制备方法中,使所述泡棉层中的第二结构部朝向所述开孔的内壁弯折并贴附于所述开孔的内壁上,具体包括:
将与开孔11配合的柱形贴合棒4与泡棉层31中与开孔11对应的部位对位,使贴合棒4的一端沿开孔11的中心轴线向开孔11内伸入,使泡棉层31中的第二结构部向开孔内弯折并贴附在开孔的内壁上,其中,贴合棒需要伸入显示模组的开孔的一端的端面的周边具圆倒角,有利于装配,便于第二结构部与显示模组的开孔内壁贴合。
显然,本领域的技术人员可以对本发明实施例进行各种改动和变型而不脱离本发明的精神和范围。这样,倘若本发明的这些修改和变型属于本发明权利要求及其等同技术的范围之内,则本发明也意图包含这些改动和变型在内。
