其中，请继续参阅图9，图9为避开第一缺口101与第二缺口102对应位置的部分剖面图。该背光模组13包括框架131与背光元件132，该框架131包括底壁1311与围绕底壁1311的侧壁1312，该框架131的底壁1311与侧壁1312共同配合形成一收容空间1313，该背光元件132设置在该收容空间1313内，该框架131的侧壁1312顶部1312A与该显示面板120固定连接，在该框架131的外表面1314与该显示面板120的侧面上形成第一胶水层141，该第一胶水层141覆盖该框架131与该显示面板120的连接处。
其中，请继续参阅图10，图10为第一缺口101与第二缺口102对应位置的部分剖面图。在围绕第二缺口102的侧壁1312B与背光元件132之间设有支撑台133，在框架131的侧壁1312顶部1312A、支撑台133的顶部1331与显示面板120的下表面1202之间形成第二胶水层142。
其中，该盖板110盖设该显示面板120及该背光模组13。
其中，该支撑台133在显示屏1中围绕背光模组13的框架131的第二缺口102的侧壁1312B形成的形状参图7中示出的支撑台133。
具体的，该背光模组13包括框架131与背光元件132，背光元件132还可以包括导光板1321、反射板1322等光学器件。该框架131包括底壁1311与围绕底壁1311的侧壁1312，底壁1311和侧壁1312可以是采用同一种材料一体成型，例如可以使用不锈钢材料一体成型底壁1311和侧壁1312。或者，也可以根据实际需要采用不同的材料形成底壁1311和侧壁1312，比如，底壁1311可以采用硬度较大的不锈钢材料形成，以提高底壁1311的承载能力，侧壁1312可以采用塑胶材料形成，以降低材料成本，其中，不同材料形成的底壁1311和侧壁1312可以采用注塑成型的方式一体成型。
在一些实施方式中，背光模组13还可以包括光源(图未示出)，光源例如可以是侧入式光源，此时光源可以位于导光板1321的侧边，以使光线从导光板1321的侧边进入导光板1321，再由导光板1321将光线导向显示面板120。当然，在其他实施例中，光源也可以是背下式光源，即光源放置在导光板1321的下方。反射板1322用于将光源的光线反射回导光板1321，以使得光源的光线可以得到充分利用。
其中，框架131用于承载光源、导光板1321以及反射板1322等器件。具体地，框架131的底壁1311和侧壁1312共同配合以形成用于放置光源、导光板1321以及反射板1322等光学器件的收容空间1313，比如，侧壁1312可以围绕在底壁1311的周缘，以和底壁1311形成凹槽结构，该凹槽的内部即为收容空间1313。框架131的侧壁1312的顶部与显示面板120的第二面1202连接。其中，侧壁1312背对收容空间1313的外表面与显示面板120的侧面之间形成第一胶水层141，以将框架131固定在显示面板120上，其中，第一胶水层141覆盖框架131的侧壁1312顶部和显示面板120的连接处，且在围绕第二缺口102的侧壁1312B与背光元件132之间设有支撑台133，在框架131的侧壁1312顶部1312A、支撑台133的顶部1331与显示面板120的下表面1202之间形成第二胶水层142。由此，可以通过第一胶水层141和第二胶水层142将框架131粘接固定在显示面板120上，可以防止水气从框架131与显示面板120的连接处进入背光模组13 内，有利于提高背光模组13的防水性能，防止内部器件受潮，除了在围绕第二缺口102的侧壁1312B与背光元件132之间设有支撑台133以通过第二胶水层142辅助背光模组13粘接在显示面板120上之外，其余避开该第二缺口102的侧壁1312直接通过第一胶水层141将框架131与显示面板120固定连接，从而省去在其余避开该第二缺口102的框架131内增加用以辅助粘接显示面板120的其他部件，比如不需要在其余避开该第二缺口102的框架131内额外设置塑胶框等部件与显示面板120粘接，原来用于设置塑胶框的位置会空出来，可以将围绕底壁1311的侧壁1312整体向收容空间1313内收缩，例如向内收缩0.25毫米，进而缩小了框架131内的空间，以此减小背光模组13的整体体积，进而可以减小显示屏1在整机中的占用空间。在围绕第二缺口102的侧壁1312B与背光元件132之间设有支撑台133并通过第二胶水层142辅助背光模组13粘接在显示面板120上，可以增大背光模组13与显示面板120的粘接强度，且不会影响到背光模组13的占用空间。另外，第一缺口101及第二缺口102内可用于放置功能组件，可以省去对应功能组件预留显示屏的非显示区域，以实现显示屏的极窄边框或者全面屏设计。
其中，第一胶水层141或者第二胶水层142可以采用热熔胶，热熔胶是一种可塑性的粘合剂，在一定温度范围内其物理状态随温度改变而改变，而化学特性不变。相比于一般胶水而言，热熔胶的黏合强度更大，固化效果更佳。且更容易控制胶水的粗细，更能满足显示屏窄边框的设计要求。另外，热熔胶属于热塑性聚氨酯，使用热熔胶粘接的产品更易于拆卸或返修。例如，该热熔胶可以为PUR热熔胶，即为湿气固化反应型聚氨酯热熔胶，主要成分是端异氰酸酯聚氨酯预聚体，PUR热熔胶的粘接性和韧性(弹性)可调节，并有着优异的粘接强度、耐温性、耐化学腐蚀性和耐老化性。
例如，第一胶水层141或者第二胶水层142可以采用uv(UVglue，无影胶)胶，uv胶又称光敏胶、紫外光固化胶，uv胶是一种必须通过紫外线(Ultraviolet Rays，UV)光照射才能固化的一类胶粘剂，它可以作为粘接剂使用，也可作为油漆、涂料、油墨等的胶料使用。uv胶固化原理是UV固化材料中的光引发剂(或光敏剂)在紫外线的照射下吸收紫外光后产生活性自由基或阳离子，引发单体聚合、交联化学反应，使粘合剂在数秒钟内由液态转化为固态。例如，第一胶水层141以及第二胶水层142可以采用黑色uv胶，该黑色uv胶可以实现挡光遮光，且具有粘接力强，固化快，点胶薄等特点，例如可以采用点胶工艺或胶水涂覆工艺在侧壁1312背对收容空间1313的外表面1314与显示面板120的侧面之间形成第一胶水层141，采用点胶工艺或胶水涂覆工艺在框架131的侧壁1312顶部1312A、支撑台133的顶部1331与显示面板120的下表面1202之间形成第二胶水层142。采用黑色uv胶形成的第一胶水层141以及第二胶水层142，可以起到遮光效果，防止产生漏光现象。
例如，该第一胶水层141或者第二胶水层142可以采用OCA(Optically Clear Adhesive，光学胶)胶等。OCA光学胶具有无色透明、高透光性(全光穿透率>99％)、高黏着力、高耐候、耐水性、耐高温、抗紫外线等特点，且具有受控制的厚度，能提供均匀的间距，长时间使用不会产生黄化、剥离及变质的问题。
在一些实施例中，请参阅图11，图11为图7在A-A方向的第二种部分剖面图。该显示面板120包括层叠设置的上偏光片121、显示层122和下偏光片123，其中，该框架13的侧壁132顶部与该下偏光片123固定连接，该第一胶水 层141设置在该框架131的外表面1314与该下偏光片123的侧面上，以覆盖所述框架131与所述下偏光片123的连接处。
其中，显示层122可以为液晶显示面板，上偏光片121和下偏光片123例如可以通过胶水或双面胶等贴合在显示层122上。
在一些实施例中，请参阅图12，图12为图7在A-A方向的第三种部分剖面图。该下偏光片123相对于该框架131向外延伸形成延伸部1231，该延伸部1321用于承载第一胶水层141，以使得该第一胶水层141在点胶过程中时更容易挂胶，以防止胶水流走进而影响到其他非点胶位置。
请参阅图13或图14，图13为图7在A-A方向的第四种部分剖面图。
图14为图7在A-A方向的第五种部分剖面图。该第一胶水层141延伸至该显示层122的侧面，以覆盖该下偏光片123与该显示层122的连接处，以及覆盖所述框架131与所述下偏光片123的连接处，可以增大第一胶水层141的粘接面积，提高背光模组13的防水性能。其中，图14与图13的差别在于，该下偏光片123相对于该框架131向外延伸形成延伸部1231，该第一胶水层141通过覆盖该伸部1231可以增大粘接面积，可以更牢固地粘结该显示面板120与该框架13的连接处。
请参阅图15或图16，图15为图7在A-A方向的第六种部分剖面图。图16为图7在A-A方向的第七种部分剖面图。该第一胶水层141延伸至该上偏光片121的侧面，以覆盖该上偏光片121与该显示层122的连接处，以及覆盖该下偏光片123与该显示层122的连接处，同时覆盖所述框架131与所述下偏光片123的连接处，可以增大第一胶水层141的粘接面积，提高背光模组13的防水性能。
在一些实施例中，请参阅图17，图17为图7在A-A方向的第八种部分剖面图。图17与图10的差别在于：在该第一胶水层141上设有第一油墨层144。其中，该第一油墨层144可以为黑色油墨层。该第一油墨层144可以防止显示模组20漏光。
在一些实施例中，如图18所示，图18为图7在A-A方向的第九种部分剖面图。图18与图17的差别在于：在该第一油墨层144上设有第三胶水层143，且该上偏光片121相对于该框架131向外延伸形成第二延伸部1211，该第二延伸部1211用于承载该第三胶水层143。
其中该第一油墨层144由高表面能或者低接触角的黑色油墨形成。高表面能或者低接触角的油墨具有高粘性，可以通过第一油墨层144增加第一胶水层141与第三胶水层143之间的粘性。通过设置第三胶水层143，可以进一步加固防水胶14的防水性能。
其中，粘接的作用是发生在相互接触的界面间，粘接作用的形成，一是湿润性，二是粘接力，两者必须同时兼备。湿润又称润湿，是液体在固体表面分子间力作用下的均匀铺展现象，也就是液体对固体的亲和性。液体的湿润主要由表面张力所引起的，液体和固体皆有表面张力，对液体称为表面张力，而固体称为表面能。湿润性主要由胶粘剂和被粘物的表面能所决定。胶粘剂对被粘物的湿润只是粘接的前提，还必须能够形成粘接力，才能达到粘接的目的。粘接力是指 胶粘剂与被粘物之间的连接力，它的产生不仅取决于胶粘剂和被粘物表面的结构和状态，而且还与粘接过程的工艺条件密切相关，粘接力是胶粘剂被粘物在界面上的作用力或结合力，包括机械嵌合力、分子间力和化学键力等。润湿是粘接的先决条件。表面能与润湿性的关系，固体表面能的大小决定了其可润湿性质，液体在固体表面能自发铺展的基本条件是液体的表面能要小于固体的表面能，液体的表面能越低、固体的表面能越高越有利于铺展进行，反之不利于铺展进行。同一液体在表面能大的固体表面润湿性好，因此，表面能是影响粘接强度的重要因素，降低胶粘剂的表面能或增大被粘物的表面能可以增强胶粘剂在被粘物上的润湿性，从而提高粘接强度。在本申请实施例中，在所述框架131与所述下偏光片123的连接处设置第一胶水层141，等待该第一胶水层141凝固之后，在该第一胶水层141上喷涂第一油墨层144，然后在第一油墨层144上设置第三胶水层143，可以将第三胶水层143作为胶粘剂，已凝固的第二胶水层141作为固体的被粘物，通过该高表面能的第一油墨层144增大第一胶水层141与第三胶水层143之间的粘结强度。
其中，水滴角的定义为在固、液、气三相交界面处，气-液相界面与固-液相界面之间的夹角，水滴角是显示固体表面湿度的尺度，利用大部分固着物液滴进行测定，低接触角表示湿度高(亲水性)，表面易粘贴。高接触水滴角表示表面显示疏水性，表面附着力差。在本申请实施例中，通过该低接触角的第一油墨层144增大第一胶水层141与第三胶水层143之间的粘结强度。
在一些实施例中，第一油墨层144可以为黑色油墨层，该第一油墨层144既可以增大第一胶水层141与第三胶水层143之间的粘结强度，又可以防止背光模组13漏光。
在一些实施例中，如图19所示，图19为图7在A-A方向的第十种部分剖面图。图19与图9的差别在于：分别在该显示面板120与该第一胶水层141之间、该框架131与该第一胶水层141之间设有第二油墨层145。其中，该第二油墨层145可以由高表面能或者低接触角的油墨形成。例如，该第二油墨层145可以为黑色油墨层。该第二油墨层145既可以增大第一胶水层141与显示面板120之间、以及第一胶水层141与框架131的粘结强度，又可以防止背光模组13漏光。
在一些实施例中，如图20所示，图20为图7在B-B方向的第二种部分剖面图。图20与图9的差别在于：在支撑台133上形成台阶部1332，背光元件132中的部分元件放置于台阶部1332上，通过该支撑台133上形成的台阶部1332来支撑和固定背光元件，使得点胶过程中背光模组13与显示面板120间更容易粘接。
在一些实施例中，如图21所示，图21为图7在B-B方向的第三种部分剖面图。图21与图20的差别在于：第二胶水层142延伸至台阶部1332与背光元件132中的部分元件之间，该第二胶水层142用于固定连接背光元件132与该框架131，以及用于固定连接该显示面板120与该框架131。通过该第二胶水层142可以增强该显示面板120与该框架131之间的粘结强度，提升背光模组13的防水效果。
在一些实施例中，该第二胶水层142为黑色遮光胶。采用黑色遮光胶形成的第二胶水层142，可以起到遮光效果，防止产生漏光现象。
本申请实施例提供的显示屏1包括显示面板120、背光模组13及盖板110，其中，显示面板120的顶端具有第一 缺口101，背光模组13的顶端具有第二缺口102，第二缺口102与第一缺口101对应设置，其中，该背光模组13包括框架131与背光元件132，该框架131包括底壁1311与围绕底壁1311的侧壁1312，该框架131的底壁1311与侧壁1312共同配合形成一收容空间1313，该背光元件132设置在该收容空间1313内，该框架131的侧壁1312顶部与该显示面板120固定连接，在该框架131的外表面1314与该显示面板120的侧面上形成第一胶水层141，该第一胶水层141覆盖该框架131与该显示面板120的连接处，且在围绕第二缺口102的侧壁1312B与背光元件132之间设有支撑台133，在框架131的侧壁1312顶部1312A、支撑台133的顶部1331与显示面板120的下表面1202之间形成第二胶水层142，该盖板110盖设该显示面板120及该背光模组13。本发明实施例可以防止水气从框架131与显示面板120的连接处进入背光模组13内，有利于提高背光模组13的防水性能，防止内部器件受潮，除了在围绕第二缺口102的侧壁1312B与背光元件132之间设有支撑台133以通过第二胶水层142辅助背光模组13粘接在显示面板120上之外，其余避开该第二缺口102的侧壁1312直接通过第一胶水层141将框架131与显示面板120固定连接，从而省去在其余避开该第二缺口102的框架131内增加用以辅助粘接显示面板120的其他部件，缩小了框架131内的空间，以此减小背光模组13的整体体积，进而可以减小显示屏1在整机中的占用空间。在围绕第二缺口102的侧壁1312B与背光元件132之间设有支撑台133并通过第二胶水层142辅助背光模组13粘接在显示面板120上，可以增大背光模组13与显示面板120的粘接强度，且不会影响到背光模组13的占用空间。另外，第一缺口101及第二缺口102内可用于放置功能组件，以省去对应功能组件预留显示屏的非显示区域，以实现显示屏1的极窄边框或者全面屏设计。
