具体实施方式
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，都属于本申请保护的范围。
本申请实施例提供了一种电子设备的显示组件。其中，电子设备包括但不限于为手机、平板电脑、可穿戴设备等。电子设备还包括摄像头模组。
如图1和图2所示，显示组件10包括层叠设置的盖板11、显示面板12和背光模组13。
其中，盖板11覆盖在显示面板12上以对显示面板12进行防护。盖板11可以通过光学透明胶14与显示面板12贴合。当然，也可以通过其他方式将盖板11与显示面板12连接。盖板11具有透光区，透光区与显示面板12的显示 区对应。对应指透光区与显示区的位置基本重合，面积基本相等，以使显示区发出的光线透过透光区形成画面。盖板11还具有不透光区，用于遮蔽盖板11所覆盖的、无需被用户看到的部件。
显示面板12用于显示画面，背光模组13用于为显示面板12提供背光源。显示面板12具有显示画面的显示区(即布设像素的区域)，显示区能透光。显示面板12还具有非显示区，非显示区内可以布设电路、走线等。显示面板12的显示区内开设有第一安装通孔h1，第一安装通孔h1的孔壁上设有挡光层15，以遮挡显示面板12发出的光线。挡光层15可以在周向上环绕第一安装通孔h1的全部孔壁或部分孔壁，和/或分布在第一安装通孔h1的轴向上的全部孔壁或部分孔壁。挡光层15靠近盖板11的一端与透光区贴合，即第一安装通孔h1的孔壁上的挡光层15延伸至透光区。挡光层15的材料包括但不限于为遮光胶，可以采用涂布工艺涂覆。
背光模组13上设有与第一安装通孔h1对准的第二安装通孔h2。优选地，对准指第二安装通孔h2的轴线与第一安装通孔h1的轴线重合。当然，对准还可以指第二安装通孔h2的轴线与第一安装通孔h1的轴线有轻微偏差。第二安装通孔h2用于限位摄像头模组21，即摄像头模组21***到第二安装通孔h2内，第二安装通孔h2的孔壁与摄像头模组21形成配合，以将摄像头模组21定位。第一安装通孔h1作为外界光线进入摄像头模组21的通道，即外界光线可透过透光区，穿入第一安装通孔h1和第二安装通孔h2，最终进入摄像头模组21。摄像头模组21采集外界光线后便可成像。
现有技术中，摄像头模组21与显示面板12并排设置，且布设在显示面板12之外(当然也位于显示面板12的非显示区之外)。在电子设备20的显示面(显示画面所在的表面)的面积一定的情况下，由于摄像头模组21占据了部分显示面的面积，导致显示面板12所占的显示面的面积受限，因此显示面板12的显示区的面积也相应受限，进而使电子设备20的屏占比较小。
相较之下，本申请的方案，通过将摄像头模组21布设在显示面板12的显示区，能将显示面板12扩大至原来摄像头的布设位置，从而将显示面板12在显示面中的面积占比做大，进而提升显示面板12的屏占比(类似具有触控屏的智能机替代了直板功能机，智能机的“键盘”布设在显示区(在显示区通 过触控实现原来键盘的功能)，显示面板12扩大至原来键盘的布设位置，从而使智能机的屏占比大于直板功能机)；通过使用背光模组13来限位摄像头模组21，能直接利用显示组件10部件有效定位摄像头模组21，无需设计复杂的定位结构；并且，通过在第一安装通孔h1的孔壁上设置挡光层15，挡光层15靠近盖板11的一端与透光区贴合，从而将显示面板12与摄像头模组21之间的主要光传输路径阻断，使显示面板12发出的光线基本无法进入摄像头模组21，因而避免了显示面板12的光线对摄像头模组21的串扰，保证了摄像头模组21的正常成像。
本实施例中，进一步的，如图2所示，挡光层15靠近盖板11的一端还可以包覆第一安装通孔h1的边沿，即挡光层15的横截面可以呈T字形，由此不仅增加了挡光层15的附着强度，更能加强挡光效果。
本实施例中，进一步的，如图2所示，挡光层15靠近背光模组13的一端可以与背光模组13贴合，即挡光层15分布在第一安装通孔h1的轴向上的整个孔壁上。由此，盖板11、挡光层15、背光模组13将显示面板12与摄像头模组21彻底隔开，使显示面板12发出的光线沿任意方向都无法进入摄像头模组21。
本实施例中，优选的，第二安装通孔h2的孔径小于第一安装通孔h1的孔径。由此可利用第二安装通孔h2进行限位，同时保证作为关键部件的显示面板12距离摄像头模组21较远，以对显示面板12进行防护(例如可避免组装时摄像头模组21擦碰到显示面板12)。
本实施例中，进一步的，如图3所示，显示面板12可以为液晶122面板，液晶122面板具有彩色滤光片基板121彩色滤光片基板121121和薄膜晶体管基板123。第一安装通孔h1在彩色滤光片基板121彩色滤光片基板121121和薄膜晶体管基板123上均形成开口。彩色滤光片基板121彩色滤光片基板121121上的开口和薄膜晶体管基板123上的开口之间连接有密封筒124，以将液晶122密封在彩色滤光片基板121彩色滤光片基板121121、薄膜晶体管基板123及密封筒124构成的密封腔内。密封筒124的内壁作为第一安装通孔h1的孔壁。使用密封筒124能在液晶122面板开通孔的情况下防止液晶122外漏，保证显示性能。密封筒124可以在液晶122面板的制程中一并形成。
优选的，密封筒124可以为液晶122面板中的黑矩阵(Black Matrix)，即密封筒124为黑矩阵材料(包括但不限于为黑色光阻薄膜)，采用黑矩阵制程制造，并具有黑矩阵的作用(防止像素间的漏光，增加对比度)。在其他实施例中，显示面板12不限于为液晶122面板，密封筒124可以采用其他材料及工艺制造。
本实施例中，进一步的，在第一实施方式中，如图3-5所示，背光模组13可以包括金属底盖131。第二安装通孔h2在金属底盖131上形成开口。金属底盖131上的开口形成第一折边1313，第一折边1313凸设在(例如垂直于)金属底盖131上的开口所在的表面。可以通过钣金加工形成第一折边1313，也可以制造独立的第一折边1313，再将第一折边1313连接到金属底盖131上的开口(包括但不限于铆接、焊接)。第一折边1313是封闭的环状以环绕金属底盖131上的开口一周；也可以是开放的环状，仅连接在金属底盖131上的开口的部分边线上。第一折边1313作为第二安装通孔h2的孔壁，即具体的可以使用第一折边1313对摄像头模组21进行限位，由此实现摄像头模组21的有效定位，避免了使用复杂的定位结构。
如图3-5所示，在第二实施方式中，与上述第一实施方式不同的是，背光模组13还可以包括塑胶套133，塑胶套133与第一折边1313相连，且塑胶套133的开孔与第一通孔t1对准。塑胶套133的开孔作为第二安装通孔h2，即具体的可以使用塑胶套133对摄像头模组21进行限位，由此实现摄像头模组21的有效定位。由于塑胶套133采用塑胶成型工艺制造，其具有较高尺寸精度，有利于减小与摄像头模组21的配合公差，增强摄像头模组21的组装强度。
本实施方式中，塑胶套133可以是贴合第一通孔t1的孔壁收容在第一通孔t1内，此时第一折边1313设在塑胶套133的外周；或者塑胶套133可以插接在第一折边1313上，即第一折边1313嵌入塑胶套133的侧壁中形成塑胶套133与第一折边1313的固定连接，此种方式能极大增强塑胶套133的连接强度，进而有利于摄像头模组21的限位。另外，本实施方式中的对准与上文的对准含义相同，此处不再赘述。
本实施例中，进一步的，如图3-5所示，金属底盖131可以包括盖体1312，盖体1312的周缘形成第二折边1311，第二折边1311凸设在(例如垂直于) 盖体1312上。可以通过钣金加工形成第二折边1311，也可以制造独立的第二折边1311，再将第二折边1311连接到盖体1312(包括但不限于铆接、焊接)。第二折边1311可以是封闭的环状以环绕盖体1312一周；也可以是开放的环状，仅连接在盖体1312周缘的部分边线上。背光模组13还包括光学部件132(包括但不限于为导光板1321、反射片、滤光片、增透膜等)，光学部件132位于盖体1312与显示面板12之间。光学部件132上开设有第二通孔t2，第一折边1313伸入第二通孔t2内，即第二通孔t2的孔径大于第一通孔t1的孔径，使第二通孔t2的孔壁围绕在第一折边1313的外周。第二折边1311位于光学部件132外周，以对光学部件132进行收容和防护。
本实施例中，光学部件132包括导光板1321，导光板1321用于接收光源的光线，并向显示面板12提供均匀的面光线。
进一步的，在一种实施方式中，如图4和6所示，第二通孔t2在导光板1321的边线处形成开口t21。其中，图6示出了光源134的光线在导光板1321内的传输路径示意，其中虚线箭头表示光源134的入射光路径(为了简明示意的目的，仅示出了光源134中部分光线的入射路径)，导光板1321的出光面为朝向观察者的表面。本实施方式中，行进到开口t21一侧的光线由于缺乏传输介质而无法继续传输到开口t21另一侧，造成开口t21另一侧无法产生面光线，导致显示面板12的相应区域无法显示。但是由于第二通孔t2在导光板1321上的开口t21位于导光板1321的边线处，开口t21另一侧无法产生面光线的区域极小，因此显示面板12上不显示的区域也极小。由此，本实施方式的方案尽量避免了导光板1321开孔对显示面板12显示的不良影响。
或者，在另一种实施方式中，与上述实施方式不同的是，如图7所示，背光模组13包括第一光源134和第二光源134，第一光源134与第二光源135分别设于第二通孔t2在导光板1321上形成的开口t22的相对两侧，以从相对的方向向导光板1321提供入射光。由此，第一光源134与第二光源135将形成互补，使导光板1321上的开口t22两侧都能产生面光线，从而避免了上述实施方式中显示面板12的相应区域不显示的缺陷。本实施方式中，导光板1321上的开口t22的位置可以根据需要任意设置，例如同样可以设在导光板1321的边线处，或居中的位置。第二折边1311位于第一光源和第二光源的外周， 以对光源进行收容和防护。
如图8-10所示，本申请实施例还提供了一种电子设备20，包括摄像头模组21和显示组件10。其中，摄像头模组21伸入第二安装通孔h2内，以使外界光线透过透光区并穿过第一安装通孔h1进入摄像头模组21，第二安装通孔h2用于对摄像头模组21进行限位。由上，本实施例的电子设备20具有更大屏占比，提升了观看体验；直接利用显示组件10部件有效定位摄像头模组21，无需设计复杂的定位结构；并且能够防止显示面板12的光线串扰摄像头模组21。
本实施例中，进一步的，如图9和10所示，摄像头模组21可以包括镜座212和安装在镜座212上的镜头211。在图10中为了便于区分镜头211与镜座212，在摄像头模组21内绘制了一条虚线，虚线以上部分为镜头211，虚线以下部分为镜座212，镜座212的径向尺寸大于镜头211的径向尺寸。镜头211伸入第二安装通孔h2内，以使第二安装通孔h2对镜头211进行限位，即背光模组13具体是在镜头211位置对摄像头模组21进行限位。镜座212卡持在第二安装通孔h2的边沿。
本实施例中，进一步的，如图10和11所示，当采用背光模组13中的塑胶套133对摄像头模组21进行限位时，塑胶套133具有第一导向斜面1331。镜座212上与镜头211连接的位置形成第二导向斜面2122，第一导向斜面1331与第二导向斜面2122相对。通过两个导向斜面的设计，能够在安装摄像头模组21至塑胶套133中时对摄像头模组21进行导向。
本实施例中，进一步的，如图9和10所示，电子设备20包括壳体22，显示组件10承载在壳体22上，壳体22与显示面板12分别位于背光模组13的相对两面。壳体22上对应第二安装通孔h2的位置开设有第三安装通孔h3，镜座212伸入第三安装通孔h3内并卡持在第二安装通孔h2的边沿。壳体22具有合适的结构强度，能够很好地承载整个显示组件10。在壳体22上开设第三安装通孔h3，令摄像头模组21穿过第三安装通孔h3安装到背光模组13上，能够减小电子设备20的整机厚度。另外，在将摄像头模组21安装到背光模组13上时，利用背光模组13进行限位，能够使摄像头模组21与显示组件10构成的装配体的装配尺寸链最短，从而减少摄像头模组21的装配公差，保障了 摄像头模组21的工作性能。
本实施例中，进一步的，如图9和10所示，壳体22的表面可以凸设安装台221，第三安装通孔h3贯穿安装台221。镜座212上远离镜头211的一端设有凸缘2121，凸缘2121与安装台221相卡持，以使凸台对镜座212进行支撑。
本实施例中，进一步的，如图9和10所示，壳体22与背光模组13之间设有密封层，密封层用于遮挡背光模组13中的光源的光线，并起到缓冲吸振作用。密封层包括但不限于使用泡棉材料制造。
本实施例中，进一步的，如图10所示，密封层上对应第二安装通孔h2的位置开设有第四安装通孔h4，第四安装通孔h4用于供镜头211穿过，密封件上位于第四安装通孔h4的周缘的区域被夹持在镜座212与背光模组13之间，此部分密封件具有缓冲吸振作用，用于避免镜座212震荡。
本申请实施例还提供了一种显示组件的制造方法，用于制造上述实施例中的显示组件。所述制造方法可以包括：
提供盖板、显示面板和背光模组，其中所述盖板具有透光区，所述显示面板具有显示区，所述显示面板的显示区开设有第一安装通孔，所述背光模组上设有第二安装通孔；
将所述盖板和所述显示面板贴合，使所述透光区对应所述显示区；
在所述第一安装通孔的孔壁上涂覆挡光材料，并使所述挡光材料流动至所述透光区朝向所述显示面板的表面；
将所述背光模组贴合在所述显示面板上背离所述盖板的一面，使所述第二安装通孔与所述第一安装通孔对准，以得到所述显示组件。
具体的，所述透光区与所述显示区的面积基本相等。所述第一安装通孔可以在显示面板的制程中形成。例如，当显示面板为液晶面板时，可以通过液晶面板的制造工艺在在薄膜晶体管基板和彩色滤光片基板上形成所述第一安装通孔及所述密封筒，以密封液晶。可以通过贴合工艺，使用光学透明胶将所述盖板和所述显示面板贴合，并使所述透光区与所述显示区的位置基本重合，以使显示区发出的光线透过透光区形成画面。
本实施例中，可以使用喷涂设备进行挡光材料的涂覆，以形成所述挡光层。所述喷涂设备可以包括夹持所述盖板与所述显示面板所成的组件的夹具，及用 于喷射挡光材料的喷嘴，喷嘴按照设定的喷涂路径行径，以完成喷涂。可以将所述盖板朝下、所述显示面板朝上定位在所述夹具上，以便于向第一安装通孔内喷涂。可以使所述挡光材料自然流动至所述透光区上朝向所述显示面板的表面，也可以使用工具(包括但不限于为风刀)所述挡光材料自然流动至所述透光区上朝向所述显示面板的表面。
本实施例中，可以将所述背光模组贴合在所述显示面板上背离所述盖板的一面，使所述第二安装通孔与所述第一安装通孔对准，从而得到所述显示组件。优选地，所述对准指第二安装通孔的轴线与第一安装通孔的轴线重合。当然，所述对准还可以指第二安装通孔的轴线与第一安装通孔的轴线有轻微偏差。
本实施例的制造方法所制造出的显示组件具有更大屏占比，直接利用显示组件部件有效定位摄像头模组，并且能够防止显示面板的光线串扰摄像头模组。
本实施例中，进一步的，在所述第一安装通孔的孔壁上涂覆挡光材料的步骤中，使所述挡光材料包覆所述第一安装通孔的边沿。由此，所形成的挡光层的横截面可以呈T字形，不仅增加了挡光层的附着强度，更能加强挡光效果。
本实施例中，进一步的，在将所述背光模组贴合在所述显示面板背离所述盖板的一面的步骤中，使所述挡光材料流动至所述背光模组的表面。由此，所形成的挡光层分布在所述第一安装通孔的轴向上的整个孔壁上。由此，盖板、挡光层、背光模组将显示面板与摄像头模组彻底隔开，使显示面板发出的光线沿任意方向都无法进入摄像头模组。
以上所述，仅为本申请的具体实施方式，但本申请的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本申请揭露的技术范围内，可轻易的想到各种等效的修改或替换，这些修改或替换都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应以权利要求的保护范围为准。
