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显示组件的制造方法、使用所述制造方法制成的显示组件，以及具有所述显示组件的电子设备。其中，显示组件用于显示画面。电子设备包括但不限于为手机、平板电脑、笔记本电脑、可穿戴设备等产品。电子设备可以具有功能模组，功能模组为具有一定机械结构及电路结构、可接收用户或环境反馈、采集用户或环境数据、用于实现特定功能的模组。功能模组包括但不限于为摄像头模组、闪光灯模组、红外模组、测距模组、光感模组、人脸识别模组、虹膜识别模组、指纹模组等。以下实施例中，以功能模组为摄像头模组为例进行描述。当然，本申请的方案实际上不限于此。
本实施例的显示组件的制造方法包括以下步骤：
01.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，所述显示区内开设有第一安装通孔；所述背光模组上开设有第二安装通孔，所述第二安装通孔的孔径小于所述第一安装通孔的孔径；
02.将所述盖板与所述显示面板贴合，使得所述透光区与所述显示区对应；
03.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，使所述第二安装通孔与所述第一安装通孔对准；
04.提供喷涂针管，所述喷涂针管具有用于射胶的流道；
05.将所述喷涂针管伸入所述第一安装通孔内，并使所述喷涂针管的流道与所述显示面板的显示面成第一锐角；
06.使用所述喷涂针管喷射遮光胶，使所述遮光胶覆盖所述第一安装通孔靠近所述背光模组的部分孔壁，以及所述背光模组朝向所述显示面板且位于所述第一安装通孔内的表面。
具体的，如图1和图2所示，在步骤01中，盖板11用于对显示面板12进行防护。盖板11具有透光区和不透光区，透光区为画面显示区，不透光区用于遮蔽盖板11之下所覆盖的、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作为显示面板12的背光源。显示面板12具有显示画面的显示区(即布设像素的区域)，显示区的面积与透光区的面积基本相等。显示区能透光。显示面板12还具有不可透光的非显示区，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可以在显示面板12的制程中形成。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还具有不可透光的非显示区，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。背光模组13用于为显示面板12提供背光，背光模组13上设有第二安装通孔h2，第二安装通孔h2的孔径小于第一安装通孔h1的孔径。
在步骤2中，例如可以通过贴合工艺，使用光学透明胶14将盖板11与显示面板12贴合。使用光学透明胶贴合的方式能将显示组件做薄，保证显示效果，且连接强度足够。当然，也可以通过其他方式将盖板11与显示面板12连接，本申请对此不做限定。其中，透光区与显示区对应指的是，透光区与显示区的位置基本重合，以便于显示区发出的光线透过透光区进入人眼形成画面。
在步骤03中，包括但不限于采用贴合工艺将背光模组13贴合在显示面板12背离盖板11的一面。优选地，使第二安装通孔h2与第一安装通孔h1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，所述对准还可以指第二安装通孔h2的轴线与第一安装通孔h1的轴线有在容许无法范围内的轻微偏差。如图2所示，由于第二安装通孔h2的孔径小于第一安装通孔h1的孔径，在背光模组13贴合到显示面板12上后，第二安装通孔h2与第一安装通孔h1的连接处形成一倒扣结构，即背光模组13朝向显示面板12的部分表面位于第一安装通孔h1内。
如图3所示，在步骤04中，可以提供一喷涂工具，喷涂工具包括容纳遮光胶(不透光，具有阻挡光线的性能)的储胶腔(图未示)，以及与储胶腔连通的喷涂针管T。喷涂针管T具有用于射胶的流道T1，遮光胶从流道T1中喷出。优选的，喷涂针管T及流道T1均为直线形，以利于胶水的出射。当然，喷涂针管T与流道T1也可以具有弯折，以满足特殊位置(如在上述的倒扣结构处，喷涂针管T可以朝所述倒扣结构处折弯，使胶水喷涂到倒扣结构处)的喷涂需求。
如图3所示，在步骤05中，可以将喷涂针管T相对工件(经上述步骤制成的、包括盖板11、显示面板12和背光模组13的组件)倾斜放入第一安装通孔h1内(喷涂针管T自然也伸入第二安装通孔h2内)，以使流道T1的出口靠近并朝向所述倒扣结构处，便于将遮光胶喷涂到此位置。具体的，可以使流道T1与显示面板12的显示面(即画面所在的平面)成第一锐角a(图中为便于标示，采用平行于显示面的一平面作为第一锐角a的测量基准)，第一锐角a的具体数值可根据第一安装通孔h1与第二安装通孔h2的孔径、孔深、喷涂针管T的体积等确定，以保证能按设计要求喷涂遮光胶即可。例如，第一锐角a可以是55度、45度等等。在实际喷涂过程中，为了便于对喷涂针管T的行进与射胶进行控制，优选的，喷涂针管T是竖直向下的，而所述工件是倾斜于水平面放置。所述工件中的显示面与水平面夹角为(90-a)度，例如所述夹角可以为35度、45度等等。或者，也可以采用图3所示的方式，将所述工件水平放置，而将喷涂针管T相对水平面(也即相对显示面)倾斜第一锐角a放置(本实施例中，统一以此种方式为例进行描述)。
如图3所示，在步骤06中，控制喷涂针管T向所述倒扣结构处喷射遮光胶。遮光胶在流道T1的出口处呈辐射状喷出(类似手电筒的光线朝各向射出。图3中用箭头表示各个射胶方向)，并覆盖在所述倒扣结构中的各处表面上。即如图4所示，喷出的遮光胶覆盖第一安装通孔h1靠近背光模组13的部分孔壁，以及背光模组13朝向显示面板12且位于第一安装通孔h1内的表面，形成遮光胶层15。本实施例中，优选的，可以将所述工件中的盖板11朝下，将第二安装通孔h2的开口朝上放置，喷涂针管T自上而下伸入到喷涂位置，从而使遮光胶在重力作用下(当然可以额外附加射胶推力)射出并覆盖到喷涂表面上。待喷胶完全固化后，即可得到图4所示的显示组件10(若有需要，可对显示组件10进行清洁，以去除溢胶及脏污)。
在本制造方法所制造的显示组件10中，第二安装通孔h2可用于对摄像头模组进行限位，即摄像头模组可插入到第二安装通孔h2内，第二安装通孔h2的孔壁与摄像头模组形成配合，以限制摄像头模组的自由度(将在下文的装置实施例中继续描述)。第一安装通孔h1作为外界光线进入摄像头模组的通道，即外界光线可穿透透光区、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。摄像头模组采集外界光线后便可成像。进一步的，摄像头模组也可同时穿入第一安装通孔h1内，从而与透光区的距离更近，便于接收更多光量的外界光线，以利于成像。或者，摄像头模组也可以不穿入第二安装通孔h2内，而是摄像头模组的入光面(外界光线由入光面进入摄像头模组内)与第二安装通孔h2的开口间隔一定距离(距离值可以为0)。
现有技术中，摄像头模组与显示面板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，由于摄像头模组占据了部分显示面的面积，导致显示面板12在显示面中所占的面积受限，因此显示面板12的显示区的面积也相应受限，进而使电子设备的屏占比较小。但是，本实施例的方案通过将摄像头模组与显示面板12堆叠设置，且将摄像头模组布置在显示面板12的显示区，能将显示面板12扩大至原来摄像头模组的布设位置，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)。
另外，本实施例的制造方法能够在第一安装通孔h1靠近背光模组13的部分孔壁，以及背光模组13朝向显示面板12且位于第一安装通孔h1内的表面形成遮光胶层15。在将摄像头模组装到显示组件10上时，摄像头模组与显示面板12及背光模组13相距较近。此时，遮光胶层15阻挡在显示面板12与摄像头模组之间，将从显示面板12与背光模组13贴合界面处漏出的光线进入摄像头模组的路径阻断，从而避免显示组件10的漏光串扰摄像头模组。优选的，可以将所述工件旋转，保持喷涂针管T的位置恒定(或者令所述工件固定，而喷涂针管T转动)，控制喷涂针管T在所述倒扣结构处表面的整周都喷涂遮光胶，以形成呈封闭环状的遮光胶层15，由此使显示组件10在任意方向的漏光都无法进入摄像头模组，从而实现良好的防光串扰效果。或者，可以使所形成的遮光胶层15为间隔分布的若干个，虽然挡光效果比遮光胶层15呈封闭环状的略差，但仍然可以阻挡显示组件10在一些方向上的漏光，以在这些方向上确保摄像头模组不会受到漏光串扰。
值得注意的是，本实施例的制造方法，通过使喷涂针管T相对显示组件10的显示面倾斜，能够确保遮光胶能喷涂到所述倒扣结构处，从而实现上述的防漏光串扰功能。相反的，若喷涂针管T并非相对倾斜设置，而是与显示组件10的显示面垂直，则遮光胶是难以喷涂到所述倒扣结构处的。
如图5所示，本实施例中，进一步的，步骤04中所提供的喷涂针管T的头部可以具有与流道T1成第二锐角b的倾斜表面T2。相应的，在步骤05中可以进一步的使倾斜表面T2朝向第一安装通孔h1的孔壁。由于倾斜表面T2的设计，喷涂针管T可以更加靠近所述倒扣位置处，减少从流道T1的出口喷出的胶的损失，有利于所述倒扣位置处覆盖足够的遮光胶。第二锐角b的具体数值可以根据第二安装通孔h2的孔径、孔深、喷涂针管T的设计要求等确定，例如可以是45度。优选的，第一锐角a与第二锐角b之和小于或等于90度，即倾斜表面T2与所述显示面所成的二面角的值小于或等于90度，此能够保证所述倒扣位置能被喷胶覆盖。当然，本实施例的制造方法并不以此为限。
如图5所示，本实施例中，进一步的，可以设计倾斜表面T2的位置，使倾斜表面T2与流道T1相贯，以在倾斜表面T2上形成出口。由此，流道T1的出口将朝所述倒扣位置的方向扩大，从而使更多的遮光胶能喷涂到所述倒扣位置处，克服了倒扣位置不易喷胶的 问题。
如图6所示，本实施例中，进一步的，步骤01中所提供的背光模组13的第二安装通孔h2的边沿(即第二安装通孔h2的开口所在的表面中，位于开口周边的表面部分)开设有凹槽13a。优选的，凹槽13a的一侧与第二安装通孔h2连通。当然，凹槽13a也可以不与第二安装通孔h2连通，而是凹槽13a与第二安装通孔h2通过一挡墙隔开。
相应的，在步骤03中，使凹槽13a的开口朝向显示面板12并至少部分位于第一安装通孔h1内。即凹槽13a远离第二安装通孔h2的孔壁的一侧(图6中为凹槽13a的左侧)可以与第一安装通孔h1的孔壁对齐(此为优选方案)，使凹槽13a恰好全部位于第一安装通孔h1内；或者，在图6所示基础上，凹槽13a的左侧可以位于第一安装通孔h1的孔壁左边，以使凹槽13a仅部分位于第一安装通孔h1内；又或者，图6所示基础上，凹槽13a的左侧可以位于第一安装通孔h1的孔壁右边，使凹槽13a全部位于第一安装通孔h1内。
相应的，在步骤06中，使得遮光胶还填充在凹槽132a中。由此，所形成的遮光胶层15能够完全遮挡背光模组13与显示面板12的贴合缝隙，保证由此贴合缝隙中漏出的光线无法进入摄像头模组。对于第二安装通孔h2的边沿不开设凹槽13a的方案，若喷涂不良，可能导致贴合缝隙处遮光胶覆盖不严密，进而导致漏光射出干扰摄像头模组。反之，在第二安装通孔h2的边沿开设有凹槽13a的方案则由于遮光胶层15进一步还延伸至凹槽13a内，能确保贴合缝隙被遮挡，因此极大降低了漏光的可能性。
如图7所示，本实施例中，进一步的，在步骤06中，使得遮光胶还覆盖第一安装通孔h1靠近透光区的部分孔壁，以使所形成的遮光胶层15延伸至透光区。由此，遮光胶层15还能进一步的阻挡由显示面板12射出的光，以避免显示面板12的发光串扰摄像头模组。
本实施例还提供了一种显示组件，使用上述实施例所述的制造方法制造。
例如，如图8和图4所示，显示组件10可包括依次层叠设置的盖板11、显示面板12、背光模组13，即盖板11与背光模组13分别设于显示面板12的相对两面。其中，盖板11具有透光区，显示面板12具有与所述透光区对应的显示区，所述显示区内开设有第一安装通孔h1。背光模组13上开设有与第一安装通孔h1对准的第二安装通孔h2，第二安装通孔h2的孔径小于第一安装通h1的孔径。第一安装通h1靠近背光模组13的部分孔壁，以及背光模组13上朝向显示面板12且位于第一安装通孔h1内的表面覆盖有遮光胶层15，遮光胶层15可通过上述的制造方法形成。
进一步的，结合图6所示，背光模组13的第二安装通孔h2的边沿开设有凹槽13a，凹槽13a的开口朝向显示面板12并至少部分位于第一安装通孔h1内。凹槽13a可以与第二安装通孔h2连通，或者与第二安装通孔h2通过一挡墙隔开。相应的，遮光胶层15还填充在凹槽13a中。
进一步的，如图7所示，遮光胶层15还覆盖第一安装通孔h1靠近透光区的部分孔壁，并延伸至透光区。
本实施例的显示组件10能够提升电子设备的屏占比，提升观看体验。并能避免显示面板12与背光模组13的贴合缝隙处的漏光串扰摄像头模组，确保摄像头模组正常工作。
如图9所示，本实施例中，进一步的，显示面板12可以为液晶面板，液晶面板具有彩色滤光片基板121和薄膜晶体管基板123，彩色滤光片基板121和薄膜晶体管基板123之间填充有液晶122。第一安装通孔h1在彩色滤光片基板121彩色和薄膜晶体管基板123上均形成开孔。彩色滤光片基板121上的开孔和薄膜晶体管基板123上的开孔之间连接有密封筒124，以将液晶122密封在彩色滤光片基板121、薄膜晶体管基板123及密封筒124构成的密封腔内。密封筒124的内壁可以作为第一安装通孔h1的孔壁。使用密封筒124能在液晶面板开通孔的情况下防止液晶122外漏，保证液晶面板的显示性能。密封筒124可以在液晶面板的制程中一并形成。
优选的，密封筒124可以为液晶面板中的黑矩阵(Black Matrix，简称BM)，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不限于为液晶面板，密封筒124可以采用其他材料及工艺制造。
如图9-图12所示，本实施例中，进一步的，背光模组13可以包括金属底盖131，金属底盖131上形成第一通孔t1，第一通孔t1的开口连接有第一折边1313，第一折边1313凸设在(例如可以垂直于)第一通孔t1的开口所在的表面。第一折边1313优选的为封闭环状构造；但也可以是开放的环状构造，仅连接在第一通孔t1的部分开口；或者，第一折边1313也可以包括连接在第一通孔t1的开口上的相间隔的若干个折边。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(包括但不限于铆接、焊接)到第一通孔t1的开口。第一折边1313优选的位于金属底盖131朝向显示面板12的一侧，当然也可以位于金属底盖131背离显示面板12的一侧。
如图9-图12所示，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(此处所述的对准与上文的对准含义相同)。塑胶套133的开孔作为第二安装通孔h2。本实施例中，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。本实施例中，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。
如图10所示，相应的，在背光模组13朝向显示面板12且位于第一安装通孔h1内的表面内凹形成凹槽13a时，凹槽13a具体是形成在塑胶套133上(图10中将凹槽13a加粗以醒目表示)，即凹槽13a具体开设在塑胶套133朝向显示面板12且位于第一安装通孔h1内的表面。
如图10-图12所示，本实施例中，进一步的，背光模组13可以包括承载在金属底盖131上的光学组件132(包括导光板、反射片、滤光片、增透膜等光学膜，以及光源)。光学组件132用于向显示面板12提供面光线。光学组件132上开设有第二通孔t2，第二通孔t2与第一通孔t1对准，第一折边1313伸入第二通孔t2内。即第一折边1313位于金属底盖131朝向光学组件132的一侧，且第二通孔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。由此，本实施例提供了一种改进后的背光模组的结构，可以实现摄像头模组21的定位，进而对提升电子设备的屏占比做出贡献。
如图13-图15所示，本实施例的电子设备20包括摄像头模组21和上述实施例中的显示组件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。遮光胶层15阻挡在摄像头模组21与显示面板12之间，用于阻挡从背光模组13与显示面板12的贴合界面漏出的光线进入摄像头模组21。本实施例的电子设备20具有更大屏占比，提升了观看体验；并且能避免显示组件10的发光串扰摄像头模组21，确保摄像头模组21正常工作。
如图15所示，本实施例中，进一步的，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11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，第二安装通孔h2对镜头211进行限位(例如，当设计塑胶套133时，塑胶套133与镜头211形成配合，以对镜头211进行限位)。镜座212卡持在第二安装通孔h2的边沿。
如图14和图15所示，本实施例中，进一步的，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的直径小于第三安装通孔h3的孔径，并大于第二安装通孔h2的孔径。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，在利用背光模组13中的第二安装通孔h2对摄像头模组21进行限位的方案中，由于此时摄像头模组21与显示组件10构成的装配体的装配尺寸链最短，因此摄像头模组21的装配误差较小，从而使得摄像头模组21的工作性能得到保障。
以上对本申请实施例进行了详细介绍，本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请的方法及其核心思想；同时，对于本领域的一般技术人员，依据本申请的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本申请的限制。
