本公开的一些实施例提供一种显示装置XZ。参见图1，显示装置XZ为具有图像(包括静态图像或动态图像，其中，动态图像可以是视频)显示功能的产品。显示装置XZ例如可以是：虚拟现实(Virtual Reality，VR)显示设备、增强现实(Augmented Reality，AR)显示设备、显示器、手机(Mobile Phone)、平板电脑(Pad)、笔记本电脑、电视、个人数字助理(Personal Digital Assistant，PDA)、超级移动个人计算机(Ultra-Mobile Personal Computer，ΜMPC)、上网本、可穿戴设备(例如智能手表)或车载显示装置XZ等，本实施例对显示装置XZ的类型不作限制。
显示装置XZ可以包括显示模组1。显示模组1为被配置为显示画面的组件；例如，显示模组1被配置为接收图像数据，并显示图像数据相应的画面。
在一些示例中，显示装置XZ还可以包括控制器等。控制器被配置为向显示模组1发送图像数据(例如，灰阶数据)；显示模组1接收该图像数据，并显示图像数据相应的画面。例如，控制器可以是中央处理器(Central Processing Unit，CPU)或者图像处理器(Graphics Processing Unit，GPU)等。
显示装置XZ还包括框架4(例如中框等)，框架4被配置为固定显示模组1、控制器等。
显示模组1可以包括显示面板ZM。显示面板ZM被配置为接收与图像数据相应数据信号(例如电压信号)，并基于该数据信号显示图像(即画面)。显示面板ZM可以具有显示区和非显示区(例如可以下文中第一显示面板的显示区和非显示区，又例如以下文中第二显示面板的显示区和非显示区)。显示面板ZM的显示区是显示面板ZM上能够显示图像的区域，显示面板ZM上除了显示区以外的区域为非显示区。其中，非显示区可以位于显示区的至少一侧(例如一个，又如多侧)，例如非显示区围绕显示区一周设置。
在一些示例中，根据显示原理的不同，显示面板ZM可以是有机发光二极管(Organic Light Emitting Diode，简称OLED)显示面板，量子点发光二极管(Quantum dot Light Emitting Diodes，简称QLED)显示面板和微发光二极管(Mini-LED或Micro-LED)显示面板等自发光显示面板中的任一种；还可以是液晶显示(Liquid Crystal Display，简称LCD)面板。
示例性地，显示面板ZM包括位于显示区的多个子像素。显示面板ZM还包括多条信号线，例如多条栅线和多条数据线。每个子像素可以与一条栅线和一条数据线耦接，被配置为响应于该栅线传输的扫描信号，写入该数据 线传输的数据信号；并基于该数据信号，出射具有相应强度的光线。
在一些示例中，多条栅线可以大致沿第一方向延伸。在一些示例中，一条栅线可以与第一方向平行。又示例性地，一条栅线的延伸方向还可以与第一方向之间存在较小的夹角。例如，该较小的夹角的取值范围为-8°～8°，又如-5°～5°。下文中，叙述的较小的夹角可以参考该夹角的取值范围，并在该取值范围内进行适应性的选择。一(例如每条)栅线可以与同一行的子像素耦接，被配置为向该行子像素传输扫描信号。示例性地，栅线位于显示区内，也可以延伸到非显示区内。
在一种可能实现的方式中，显示面板ZM还可以包括位于非显示区的栅极驱动电路，此时，栅极驱动电路可以称为GOA(Gate On Array)电路。该栅极驱动电路与多条数据线耦接，被配置为向栅线提供扫描信号。例如，栅极驱动电路可以设置在显示区沿第一方向的一侧(例如左侧或右侧)。在另一些示例中，栅极驱动电路可以为栅极驱动芯片，不包含在显示面板ZM中，但与显示面板ZM中的多条栅线耦接。
在一些示例中，多条数据线可以大致沿第二方向延伸。其中，第二方向垂直于第一方向。示例性地，一条数据线可以与第二方向平行。在一些示例中，一条数据线还可以与第二方向之间存在较小的夹角。一(例如每条)数据线可以与同一列的子像素耦接，被配置为向该列的子像素提供数据信号。示例性地，数据线位于显示区内，也可以延伸到非显示区内。
在一种可能实现的方式中，显示面板ZM还可以包括驱动芯片，具体可以是驱动IC，例如，源极驱动IC或显示驱动电路(Display Driver Integrated Circuit，DDIC)等。驱动芯片与显示面板ZM耦接，例如可以绑定到显示面板ZM的非显示区。驱动芯片被配置为基于接收到的图像数据，向显示面板ZM提供相应的数据信号。在一些示例中，驱动芯片与多条数据线耦接，被配置为向数据线提供数据信号。
为了方便描述，第一方向可以是显示面板的长边的延伸方向。第二方向可以显示面板的宽边的延伸方向。第一方向与第二方向交叉，例如垂直而建立直角坐标系。
在一些示例中，显示装置XZ还可以包括驱动芯片，具体可以是驱动IC，例如，源极驱动IC或显示驱动电路(Display Driver Integrated Circuit，DDIC)等。驱动芯片与显示面板ZM耦接，例如可以绑定到显示面板ZM的非显示区。驱动芯片被配置为基于接收到的图像数据，向显示面板ZM提供相应的数据信号。
在相关技术中，继续参见图1，显示模组1还包括复合棱镜膜FH，例如，将下文中示例一的显示组件或下文中示例二的第二显示面板固定在框架4上，复合棱镜膜FH(例如下文中的第一复合棱镜膜或第二复合棱镜膜)固定在框架4上；第二显示面板或显示组件与复合棱镜片之间存在空气层，那么光线在通过空气层的上、下表面时会产生反射，使得显示模组1的显示效果不好。
本公开的一些实施例提供了一种显示模组，以解决第二显示面板或显示组件与复合棱镜片之间存在空气层的问题。其中，本公开的实施例提供了两种显示模组，为了做出区分，该两种显示模组可以分别称为第一显示模组和第二显示模组。下面通过两个示例介绍第一显示模组和第二显示模组。
示例一：参见图2～图11，提供第一显示模组10。
参见图2和图3，第一显示模组10可以包括显示组件110。
参见图4，显示组件110包括第一显示面板112和第一偏光片113。第一偏光片113设置在第一显示面板112的非显示侧。例如，第一偏光片113贴附在第一显示面板112(例如液晶显示面板)的非显示侧。第一显示面板112的描述可参考显示装置中对显示面板的相关描述。
在一些示例中，继续参见图4，显示模组还包括第二偏光片111；第二偏光片111设置在第一显示面板112(例如液晶显示面板)的显示侧。例如第二偏光片111贴附在第一显示面板112(例如液晶显示面板)的显示侧。其中，第一偏光片113的偏振方向和第二偏光片111的偏振方向垂直。
继续参见图2和图3，第一显示模组10还包括第一胶层120和第一复合棱镜膜130。第一胶层120将显示组件110中的第一偏光片113与第一复合棱镜膜130粘合。
第一胶层120的雾度可以是小于1％。第一胶层120的透过率可以是大于90％(例如90％、92％、94％、96％、99％、100％等)。第一胶层120可以是雾度较低的高透胶。例如第一胶层120可以是OCA(Optically Clear Adhesive)光学胶。第一胶层120的杨氏模量大于270KPa，减少第一胶层120与第一复合棱镜膜130之间产生内应力。第一胶层120的厚度为50μm～125μm，第一胶层120的厚度较厚，成本较高；第一胶层120的厚度胶薄，粘贴能力弱。
继续参见图2和图3，第一复合棱镜膜130包括雾度层131和第一棱镜层133。
雾度层131可以是具有一定雾度的光学膜片。第一棱镜层133设置在第一偏光片113远离第一显示面板112的一侧；雾度层131设置在第一棱镜层133上，且位于第一棱镜层133与第一偏光片113之间。即第一显示面板112、 第一偏光片113、第一胶层120和第一复合棱镜膜130依次层叠设置。第一胶层120将第一复合棱镜膜130中的雾度层131与显示组件110中的第一偏光片113粘接。
在一些示例中，第一复合棱镜膜130还包括第一基材层135，第一支撑层的材料可以是热塑性聚酯，例如可以是聚对苯二甲酸乙二醇酯(Polyethylene terephthalate，简称PET)。第一棱镜层133设置在第一基材层135上，雾度层131设置在第一棱镜层133远离第一基材层135的一侧。
第一胶层120在第一显示面板112所在平面的正投影至少覆盖第一显示面板112的显示区。在一些示例中，第一胶层120在第一显示面板112所在平面的正投影覆盖第一显示面板112的显示区。在另一些示例中，第一胶层120在第一显示面板112所在平面的正投影覆盖第一显示面板112的显示区和非显示区。
这样一来，利用第一胶层120将第一复合棱镜膜130中的雾度层131与显示组件110中的第一偏光片113粘接，使得显示组件110和第一复合棱镜膜130形成全贴合的第一显示模组10。这样一来，在全贴合的第一显示模组10中，第一偏光片113与第一复合棱镜膜130之间没有空隙(即去除了相关技术中的空气层)。从而使得第一显示模组10的内部没有更多的镜面反射光线，使得的第一显示模组10的显示画面清晰。此外还降低了第一显示模组10的厚度，使第一显示模组10超轻薄化的方向发展。
入射光线(例如可以是下文中的显示装置中的背光层发出的光线)通过第一棱镜层133时，入射光线的入射角小于预设角度的入射光线可以通过第一棱镜层133折射出去；其余入射光线不满足第一棱镜层133的折射条件，而被第一棱镜层133反射回到背光层中，并由背光层底部的反射片反射，再次入射到第一棱镜层133中。这样，背光层发出的入射光线在第一棱镜层133的作用下，不断的循环利用，从而达到增亮效果。
光线通过第一棱镜层133进入到雾度层131时，由于雾度层131具有雾度，例如雾度层131的雾度大于或等于70％(例如雾度层131的雾度可以是70％、72％、74％、76％、78％、80％、82％、84％、86％、88％、90％、92％、94％、96％、98％、99％、100％等)；光线被雾度层131进行散射，从而可以提升第一显示面板112的辉度。
参见图5和图6，雾度层131包括第一接合剂层1312和多个第一扩散粒子1311；多个第一扩散粒子1311分散在第一接合剂层1312中，这样一来，设置的多个第一扩散粒子1311可以起到光线折射和散射的效果。第一接合剂 层1312的材料可以是具有粘贴能力的树脂，例如丙烯酸树脂。
在一些实施例中，多个第一扩散粒子1311包括多个第一粒子DY，第一粒子DY的硬度大于或等于20MPA。这样一来，在第一胶层120挤压雾度层131中的第一粒子DY的情况下，由于第一粒子DY的硬度较大，使得第一粒子DY不会发生形变；从而可以避免第一粒子DY产生内应力，而使得雾度层131与第一胶层之间产生彩虹纹。其中，第一粒子DY的材料可以是硬度较大的有机材料，例如该有机材料可是聚酯树脂，聚酯树脂可以是聚甲基丙烯酸甲酯(Poly Methyl Methacrylate，简称PMMA)。
在一些示例中，针对多个第一粒子DY中的至少一些(例如多个第一粒子DY；又例如一部分的多个第一粒子DY)，每个第一粒子DY中的一部分嵌设在第一接合剂层1312中，另一部分凸出于第一接合剂层1312且与第一胶层120粘接。对于多个第一粒子DY中的一部分可以嵌设在第一接合剂层1312内，该多个第一粒子DY中的一部分对光的散射有损失。
例如，针对全部的第一粒子DY，每个第一粒子DY的一部分嵌设在第一接合剂层1312中；每个第一粒子DY的另一部分凸出于第一接合剂层1312且与第一胶层120粘接。
这样一来，第一粒子DY中裸露于第一接合剂层1312外的部分可以起到折射和散射光线的效果。从第一粒子DY中裸露于第一接合剂层1312外的部分出来的折射光线和散射光线，可以直接传播至第一偏光片113。
在一些示例中，多个第二粒子DR的粒径可以相同，也可以相同。例如第一粒子DY的粒径为2μm～30μm(2μm、5μm、10μm、15μm、20μm、25μm和30μm等)。
示例性地，继续参见图5和图6，多个第一扩散粒子还包括多个第二粒子DR。在一些示例中，多个第二粒子DR的硬度小于20MPA。第二粒子DR的材料可以是一些硬度较小的有机材料，例如可以是聚酯树脂，聚酯树脂可以是聚甲基丙烯酸正丁酯(PBMA)。
多个第二粒子DR分散在第一接合剂层1312中。这样一来，第一粒子DY和第二粒子DR均可以起到折射光线和散射光线的效果。第一粒子DY的硬度大于第二粒子DR的硬度；多个第一粒子DY的总质量大于多个第二粒子DR的总质量；例如第一粒子DY的密度大于或等于第二粒子的密度，使得多个第一粒子DY的总体积大于个第二粒子DR的总体积。这样一来，第一粒子DY可以到支撑的作用，可以减少第一胶层120对第二粒子DR和第一接合剂层1312的挤压。从而第二粒子DR可以起到光线折射和散射的效果，而不起 到支撑的效果。进而在第一粒子DY和第二粒子DR的配合下，雾度层131的支撑效果较好，光线折射和散射效果也较好。
示例性地，多个第一粒子DY的平均粒径大于多个第二粒子DR的平均粒径。使得第一粒子DY可以起到很好的支撑效果。在一些示例中，多个第二粒子DR的粒径可以相同，也可以相同。例如，第二粒子DR的粒径为2μm～10μm(2μm、3μm、4μm、5μm、6μm、7μm、8μm、9μm和10μm等)。
示例性地，多个第一粒子DY的总质量与第一接合剂层1312的质量之比大于或等于60％。在一些示例中，多个第二粒子DR的总质量与第一接合剂层1312的总质量之比小于或等于40％。这样一来，使得多个第一粒子DY可以起到支撑的作用。
表1为雾度层的配比表
通过表1，可以得到雾度层的雾度为89％～95％。
示例性地，参见图5和图7，雾度层131具有取样区，所述取样区在所述第一显示面板112上的正投影位于所述第一显示面板112的显示区内，所述取样区的单位长度至少大于或等于150μm(例如150μm、200μm、250μm、300μm、350μm、400μm、450μm、500μm、550μm、600μm等)。其中第一显示面板112的显示区的单位长度大于等于取样区的单位长度。单位长度可以理解为正方形，例如，取样区的单位长度为150μm的情况下，该取样区可以表示为150μm×150μm的正方形。
在取样区内，最矮第一粒子DY1与第一偏光片113的距离，小于第二粒子与第一偏光片113的距离D1。这样一来，该距离D1使得第一胶层120可以接触到第一粒子DY，不接触到第二粒子DR和第一接合剂层1312。也就是说，在第一粒子DY起到支撑的作用，可以消除第一胶层120对第二粒子DR和第一接合剂层1312的挤压；从而避免了第二粒子DR会发生形变，产生内应力的情况。
最矮第一粒子DY1为所有凸出于第一接合剂层1312的上表面的第一粒子DY中，最远离第一偏光片113的第一粒子DY；可以理解为，最矮第一粒子DY1为所有凸出于第一接合剂层1312的上表面ZBM的第一粒子DY中， 最靠近第一接合剂层1312的上表面ZBM的第一粒子DY。其中，第一接合剂层1312的上表面ZBM可以是第一接合剂层1312中最靠近第一偏光片113的表面。
在一些示例中，在取样区内，最矮第一粒子DY1与第一偏光片113的距离，小于最高第二粒子DR1与第一偏光片113的距离D1。这样一来，该距离D1使得第一胶层120可以接触到第一粒子DY，不接触到第二粒子DR和第一接合剂层1312。此外，最高第二粒子DR中凸出于第一接合剂层1312的上表面ZBM的部分可以提高光的散射和折射。例如该距离D1为3.5μm～10μm(3.5μm、4μm、4.5μm、5μm、5.5μm、6μm、6.5μm、7μm、7.5μm、8μm、8.5μm、9μm、9.5μm和10μm等)。
最高第二粒子DR为所有凸出于第一接合剂层1312的上表面ZBM的第二粒子DR中，最靠近第一偏光片113的第一粒子DY；可以理解为，最高第二粒子DR1为所有凸出于第一接合剂层1312的上表面ZBM的第二粒子DR中，最远离第一接合剂层1312的上表面ZBM的第一粒子DY。
在一些示例中，在取样区内，最矮第一粒子DY1与第一偏光片113的距离，小于位于第一接合剂层1312中的第二粒子与第一偏光片113的距离。
示例性地，第二粒子DR的至少一部分嵌设在中。例如，第二粒子DR的一部分嵌设在第一接合剂层1312中，另一部分裸露在第一接合剂层1312外。这样一来，第二粒子DR裸露在第一接合剂层1312外的部分可以折射和散射光线。具体的，从第二粒子DR中裸露于第一接合剂层1312外的部分出来的折射光线和散射光线可以直接进入到第一偏光片113，避免在第一接合剂层1312的上表面、下表面反射，而减弱光通量；从而增加了雾度层131的折射能力。又例如，第二粒子DR嵌设在第一接合剂层1312中。
在一些实施例中，规律排列的背光层所发出的光未经散射进入到第一棱镜层133(包括规律分布的多个第一棱镜单元)中，光线之间会发生光线干涉。因此，继续参见图5和图6，第一复合棱镜膜130还包括第一背涂层136。第一背涂层136设置在第一棱镜层133远离第一显示面板112的一侧。这样一来，第一背涂层136可以减小或消除背光层与第一棱镜层133之间的干涉光线。在一些示例中，第一基材层135设置在第一棱镜层133远离第一偏光片113的一侧。第一背涂层136设置在第一基材层135远离第一棱镜层133的一侧。
第一背涂层136包括第二接合剂层1361和分散在第二接合剂层1361中的多个第二扩散粒子1362。规律分布的背光层发出的光线经过第二扩散粒子 1362形成散射光线，由于该散射光线的传播规律与第一棱镜层133的排布规律不相同，因此减少了背光层与第一棱镜层133之间的干涉光线。在一些示例中，第二接合剂层1361设置在第一基材层135远离第一棱镜层133的一侧。
示例性地，继续参见图5，显示装置在使用扩散板的情况下，第一背涂层136的雾度为35％～70％(例如35％、40％、45％、50％、55％、60％、65％、70％等)，利用该第一背涂层136的雾度和扩散板双重的作用，可以消除背光层与第一棱镜层133之间的干涉光线，达到光线匀化散射的作用，从而起到雾化遮蔽作用。
在第一背涂层136的雾度为35％～70％的情况下，第二扩散粒子1362的材料为可以是有机材料，例如聚酯树脂，聚酯树脂可以是聚甲基丙烯酸甲酯(Poly Methyl Methacrylate，简称PMMA)。第二扩散粒子1362的粒径为5μm～10μm(例如5μm、6μm、7μm、8μm、9μm、10μm等)。
又示例性地，显示装置在不使用扩散板的情况下，光线还会在第一棱镜层133中产生水平状的钻石纹路。并且光线在通过显示装置的棱镜膜的情况下，第一棱镜层133和棱镜膜之间还会产生网状的钻石纹。第一背涂层136的雾度大于等于90％(例如90％、92％、94％、96％、98％、100％等)，这样一来，增大了第一背涂层136的雾度，从而增强了光线匀化散射的能力。进而增加了第一背涂层136干扰光线干涉的能力，使得第一背涂层136雾化遮蔽作用增强。
在第一背涂层136的雾度大于或等于90％的情况下，第二扩散粒子1362的包括多个第六粒子和第五粒子。第六粒子的材料为有机物，例如可以是聚酯树脂。第五粒子材料可以是金属氧化物，例如可以是钛氧化物。第二扩散粒子1362的粒径小于或等于4μm(例如0.1μm、0.5μm、1μm、1.5μm、2μm、2.5μm、3μm、3.5μm、4μm等)。多个第五粒子的总质量与多个第六粒子总质量为40％～60％(例如40％、43％、45％、47％、50％、53％、57％、60％等)。
在一些示例中，第二扩散粒子1362的一部分嵌设在第二接合剂层1361中，第二扩散粒子1362的另一部分凸出于第二接合剂层1361。
在一些实施例中，参见图8和图9，第一复合棱镜膜130还包括第一增亮层134。第一增亮层134设置在第一基材层135与第一棱镜层133之间。由于第一增亮层134的折射率小于第一基材层135的折射率，这样一来，光线经过第一基材层135和第一增亮层134进入到第一棱镜层133，相比于光线经过第一基材层135进入到第一棱镜层133而言；增加的第一增亮层134可以增大进入到第一棱镜层133光线的入射角和光程，从而提升了第一显示面板112 的显示均一性。
在一些示例中，第一增亮层134的折射率为1.49～1.51(1.49、1.50、1.51等)。第一基材层135的材料可以是有机材料，例如可以是光学树脂，因此，第一基材层135的折射率为1.62。沿第一基材层135、第一增亮层134和第一棱镜层133的层叠方向上(即显示模组的厚度方向上)，第一增亮层134的厚度为15μm～50μm(15μm、20μm、25μm、30μm、35μm、40μm、45μm、50μm等)。
在一些实施例中，继续参见图10，第一棱镜复合膜还包括偏光增亮层137。偏光增亮层137设置在第一棱镜层133与雾度层131之间。在一些示例中，第一复合棱镜膜还包括第二基材层132，第二基材层132设置在偏光增亮层137和第一棱镜层133之间。例如，偏光增亮层137可以粘贴在第二基材层132上。其中，第二基材层132的材料描述可参考第一基材层135的材料相关描述。
在一些实施例中，参见图11，第一显示面板112包括位于显示区的多个子像素XS；该多个子像素XS中包括用于出射第一颜色光的第一子像素、用于出射第二颜色光的第二子像素和用于出射第三颜色光的第三子像素。其中，第一颜色、第二颜色和第三颜色为三基色(例如红色、绿色和蓝色)。示例性的，第一显示面板112可以包括红色子像素、绿色子像素和蓝色子像素。
多个子像素XS排成多列。第一方向为第一显示面板112的长边的延伸方向。可以理解为，第一方向垂直于多列子像素的排列方向，并与第一显示面板112所在平面平行。
第一棱镜层133包括多个第一棱镜单元1331。在一些示例中，第一棱镜单元1331的形状为三棱柱。例如第一棱镜单元1331可以是顶角为90°的三棱柱。
其中，在第一方向上，第一棱镜单元1331的尺寸D3与子像素XS的尺寸D2的比值等于n；n为除过0.5和正整数之外的自然数(例如n为0～0.5、0.5～1、1～2、2～3等)。这样一来，可以避免在多个子像素XS与多个第一棱镜单元1331之间产生干涉光线。
例如，在第一方向上，第一棱镜单元1331的尺寸D3与子像素XS的尺寸D2的比值可以是0.1～0.49(0.1、0.2、0.3、0.4、0.43、0.45、0.47和0.49等)。又例如，在第一方向上，第一棱镜单元1331的尺寸D3与子像素XS的尺寸D2的比值还可以是0.51～0.99(0.51、0.53、0.57、0.6、0.63、0.67、0.7、0.8、0.9和0.99等)。
参见图12，第一棱镜层133包括多列第一棱镜单元1331；第一棱镜单元1331的延伸方向与第一显示面板112的长边的延伸方向之间的夹角θ大于等于30°，且小于等于150°(例如，30°、40°、50°、60°、70°、80°、90°、100°、110°、120°、130°、140°、150°等)。这样一来，该夹角θ有助于改善斜纹，可以避免在第一偏光片113与第一复合棱镜膜130之间产生摩尔纹。该夹角θ大于等于90°有助于改善视角。
本公开的实施例还提供一种第一显示模组的组装方法，该组装方法包括：
步骤一、制备第一复合棱镜膜，可以包括：步骤S110～步骤S170。
步骤S110，形成第一基材层。步骤S120，在第一基材层上形成第一增亮层。步骤S130，在第一增亮层远离第一基材层的一面上形成第一棱镜层。步骤S140，在第一基材层远离第一增亮层的一面上形成第一背涂层。步骤S150，在第一棱镜层远离第一基材层的一面上形成第二基材层。步骤S160，在第二基材层远离第一基材层的一面上形成偏光增亮膜。步骤S170，在偏光增亮膜远离第一基材层的一面上形成雾度层。其中，在一些示例中，先执行步骤S150、步骤S160和步骤S170，再执行步骤S130和步骤S140。
步骤二、制备显示组件，可以步骤包括：
在第一显示面板的非显示侧形成第一偏光片。例如将第一偏光片贴附在第一显示面板的非显示侧。
步骤三、利用第一胶层，将第一复合棱镜膜与显示组件中的第一偏光片粘合。
示例二：参见图13～图20，提供第二显示模组20。
参见图13和图14，第二显示模组20包括第二显示面板210和第二复合棱镜膜220。第二复合棱镜膜220贴合在第二显示面板210的非显示侧。第二显示面板210的相关描述可以参考显示装置中对显示面板的相关描述。在一些示例中，示例一中的第一显示面板和示例二中的第二显示面板210可以相同(例如均可以是液晶显示面板)；也可以不相同。
第二复合棱镜膜220包括第二胶层221、第三胶层225、第二棱镜层226和偏光单元222。偏光单元222设置在第二显示面板210的非显示侧。第二胶层221将第二显示面板210与偏光单元222粘贴。第三胶层225将第二棱镜层226与偏光单元222粘贴。即第二显示面板210、第二胶层221、偏光单元222、第三胶层225和第二棱镜层226依次层叠设置。
偏光单元222包括层叠设置的偏光层G2和第一支撑层G1。在一些示例中，第二胶层221将第一支撑层G1与第二显示面板210粘合，偏光层G2设 置在第一支撑层G1远离第二显示面板210的一侧；即第二棱镜层226、第三胶层225、第一支撑层G1、偏光层G2和第二显示面板210依次层叠设置。在另一些示例中，第二胶层221将偏光层G2与第二显示面板210粘合，第一支撑层G1设置在偏光层G2远离第二显示面板210的一侧。即第二棱镜层226、第三胶层225、偏光层G2、第一支撑层G1和第二显示面板210依次层叠设置。
第二胶层221在第二显示面板210所在平面的正投影至少覆盖显示区。在一些示例中，第二胶层221在第二显示面板210所在平面的正投影覆盖显示区。在另一些示例中，第二胶层221在第二显示面板210所在平面的正投影覆盖显示区和非显示区。
这样一来，利用第二复合棱镜膜220中的第二胶层221，使第二显示面板210和第二复合棱镜膜220全贴合。从而第二显示面板210与第一复合棱镜膜之间没有空隙(即去除了第二显示面板210与第一复合棱镜膜之间的空气层)。这样一来，第二显示模组20的内部没有更多的镜面反射光线，使得第二显示模组20的显示画面清晰。同时还降低了第二显示模组20的厚度，使显示模组超轻薄化的方向发展。
在一些示例中，第二显示模组20还包括上偏光片；上偏光片设置在第二显示面板210(例如液晶显示面板)的显示侧(即出光侧)。例如上偏光片贴附在第二显示面板210(例如液晶显示面板)的显示侧。其中，上偏光片的偏振方向和偏光层G2的偏振方向垂直。
第二棱镜层226具有多个第一出光面2261，第一出光2261面相对于第二显示面板210所在平面倾斜设置。第一出光面2261为凹凸不平的面，使得第二棱镜层226中的第一出光面2261具有一定的雾度；这样还避免增加第二棱镜层226的厚度。
第二胶层221、第一支撑层G1和第三胶层225中的一者的雾度处理。例如，第二胶层221雾度处理。又例如，第一支撑层G1雾度处理。又例如，第三胶层225雾度处理。
本公开还提供第一对比方案，第一对比方案包括：第二棱镜层226、第三胶层225、偏光单元(第一支撑层G1、偏光层G2)和第二显示面板210依次层叠设置；将第一出光面2261、第二胶层221、第一支撑层G1和第三胶层225中的一者雾度处理。
第一对比方案要解决第二显示面板210与第二复合棱镜膜220之间的彩虹纹，就需要增大第一出光面2261、第二胶层221、第一支撑层G1和第三胶 层225中的一者的雾度。从而增加了第一出光面2261、第二胶层221、第一支撑层G1和第三胶层225的厚度，并且随着雾度的增加，厚度会翻倍的加厚。同时，透光性降低，工艺难度会翻倍的增加。这样一来，使得第一对比方案的显示模组的厚度较厚，不利于使显示模组超轻薄化方向发展。此外，第二胶层221和第三胶层225的雾度增加，使得第二胶层221和第三胶层225粘贴能力降低，从而显示模组容易出现开胶脱落等情况。显示模组的发黄比较严重。
那么，在信赖性测试(例如高温测试，高湿测试)时，由于第一对比方方案的信赖性测试的条件与第二显示面板的信赖性测试条件相同，使得第一对比方案不能通过信赖性测试。
本公开还提供第二对比方案，第二对比方案包括：第二棱镜层226、第三胶层225、偏光单元(第一支撑层G1、偏光层G2)和第二显示面板210依次层叠设置；将第二胶层221、第一支撑层G1和第三胶层225中的至少两者雾度处理。此外，第二胶层221和第三胶层225均雾度处理，使得显示模组的发黄比较严重。
那么，在信赖性测试(例如高温测试，高湿测试)时，由于第一对比方方案的信赖性测试的条件与第二显示面板的信赖性测试条件相同，使得第二对比方案不能通过信赖性测试。
相比于第一对比方案和第二对比方案，在本公开的实施例中，利用第一出光面2261的雾度、以及二胶层221、第一支撑层G1和第三胶层225中的一者的雾度。可以解决第二显示面板210与第二复合棱镜膜220之间的彩虹纹。此外，第一出光面2261的雾度较小，第二胶层221、第一支撑层G1和第三胶层225中的一者的雾度较小；使得厚度也较薄，工艺也较为简单，透光性也较好。
示例性地，第二胶层221、第一支撑层G1和第三胶层225中的一者的雾度为45％～60％(例如，45％、47％、49％、50％、53％、55％、57％、60％等)。例如，第二胶层221的雾度为45％～60％。又例如，第一支撑层G1的雾度为45％～60％。又例如，第三胶层225的雾度为45％～60％。
在一些示例中，第二胶层221、第一支撑层G1和第三胶层225中的一者的雾度为45％～60％的情况下，另二者的雾度小于1％。例如，第二胶层221的雾度为45％～60％的情况下，第一支撑层G1和第三胶层225的雾度均小于1％。在此情况下，第二胶层221可以是雾度胶，第三胶层225可以是树脂胶。又例如，第一支撑层G1的雾度为45％～60％的情况下，所第二胶层221和第 三胶层225的雾度小于1％。在此情况下，第二胶层221可以是压敏胶，第三胶层225可以是树脂胶。又例如，第三胶层225的雾度为45％～60％的情况下，第二胶层221和第一支撑层G1的雾度小于1％。在此情况下，第二胶层221可以是压敏胶。在此情况下，第二胶层221可以是压敏胶，第三胶层225可以是雾度胶。
在一些示例中，偏光单元222还包括第二支撑层G3。第二支撑层G3的材料的相关描述可参考第一支撑层G1的材料的相关描述。
第二支撑层G3、偏光层G2和第一支撑层G1依次层叠设置；第二支撑层G3的雾度小于1％。在一些示例中，参见图16，从下到上，第一支撑层G1、偏光层G2和第二支撑层G3依次层叠设置。即第三胶层225将第一支撑层G1与第二棱镜层226粘合的情况下，第二胶层221将第二支撑层G3与第二显示面板210粘合。在另一些示例中，参见图15，从下到上，第二支撑层G3、偏光层G2和第一支撑层G1依次层叠设置。即第三胶层225将第二支撑层G3与第二棱镜层226粘合的情况下，第二胶层221将第一支撑层G1与第二显示面板210粘合。
在一些示例中，第一出光面2261的雾度为40％～50％(例如，40％、42％、44％、45％、47％、49％、50％等)。
在一些示例中，参见图17，第一出光面2261具有多个凹陷部AX。在一些示例中，参见图18，第一出光面2261具有多个凸起部TQ。在一些示例中，参见图19，第一出光面2261具有多个凹陷部AX和多个凸起部TQ。其中，凹陷部AX的尺寸小于或等于0.5μm(例如0.5μm、0.4μm、0.3μm、0.2μm、0.1μm等)。凸起部TQ的尺寸小于或等于0.5μm(例如0.5μm、0.4μm、0.3μm、0.2μm、0.1μm等)。
在一些示例中，参见图20，第二棱镜层226包括多个第二棱镜单元2262，第二棱镜单元2262包括棱镜本体LJB和多个第三扩散粒子DSK，棱镜本体LJB具有底面DM和与底面DM连接的倾斜面QXM。其中，多个第三扩散粒子DSK粘贴在棱镜本体LJB的倾斜面QXM上形成第二棱镜单元2262的第一出光面2261。
在一些示例中，第三扩散粒子DSK的粒径小于或等于0.5μm(例如0.5μm、0.4μm、0.3μm、0.2μm、0.1μm等)。
在一些示例中，多个第三扩散粒子DSK包括：多个第三粒子和多个第四粒子；第三粒子的材料为有机材料，例如可以是聚酯树脂；第四粒子的材料为可以是金属氧化物，例如可以是钛氧化物。在多个第三扩散粒子DSK中， 多个第四粒子的总质量与多个第三粒子的总质量比值为30％～50％(30％、34％、35％、37％、39％、40％、44％、46％、49％、50％等)。
在一些示例中，第二棱镜层226包括多个第二棱镜单元2262，第二棱镜单元2262具有第二出光面EFG和两个第一出光面2261，第二出光面EFG与两个第一出光面2261连接；第二出光面EFG和第二显示面板210所在平面平行；第二出光面EFG与第三胶层225粘接。这样一来，使得第二棱镜单元的横截面为梯形。
在一些示例中，参见图14，第二复合棱镜膜220还包括第三基材层228和第二增亮层227。第三基材层228设置在第二棱镜层226远离偏光单元222的一侧。第二增亮层227设置在第三基材层228与第二棱镜层226之间，且与第三基材层228接触；第二增亮层227的折射率小于第三基材层228的折射率。第二增亮层227和第三基材层228的效果，可参考第以增亮层和第一基材层所带来的效果，不再赘述。
在一些示例中，第二复合棱镜膜220还包括离型膜。离型膜位于第二胶层221远离偏光单元222一侧，且可剥离地设置在第二胶层221上。在将第二复合棱镜膜220与第二显示面板贴合时，先剥离离型膜，然后利用第二复合棱镜膜220的第二胶层221与第二显示面板粘合。这样一来，离型膜可以使得第二胶层221的粘贴性很好。
在一些实施例中，继续参见图14，第二复合棱镜膜220还包括第二背涂层229。背涂层设置在第二棱镜层226远离第二显示面板210的一侧。第二背涂层229包括第三接合剂层2291和分散在第三接合剂层2291中的多个第四扩散粒子2292；第二背涂层229的雾度大于或等于90％，或者，第二背涂层229的雾度为35％～70％。在第二背涂层229的雾度为35％～70％的情况下，第四扩散粒子2292的材料为有机材料，例如可以是有机材料，例如可以是聚酯树脂，第四扩散粒子2292的粒径为5μm～10μm。在第二背涂层229的雾度大于或等于90％的情况下，第四扩散粒子2292包括第八粒子和第七粒子，第八粒子的材料为有机物，所述第七粒子的材料为可以是金属氧化物，例如可以是钛氧化物；第四扩散粒子2292的粒径小于或等于4μm。第二背涂层229的成分、材料、效果等描述可参考示第一背涂层的成分、材料、效果等的相关描述，不再赘述。
本公开的实施例提供一种第二显示模组的组装方法，该组装方法包括：
步骤四、制备第二复合棱镜膜，可以包括：步骤S210～步骤S270。
步骤S210，在第三基材层上形成第二棱镜层。步骤S220，利用第三胶层，将偏光单元和第二棱镜层粘合，偏光单元位于远离第二棱镜层远离第三基材层的一侧。步骤S230，在偏光单元远离第二棱镜层的一侧面上形成第二胶层。
在一些示例中，在步骤S210与步骤S220之间，制备第二复合棱镜膜的步骤还可以包括：层叠设置的第一支撑层和偏光层。在另一些示例中，在步骤S210与步骤S220之间，制备第二复合棱镜膜的步骤还可以包括：偏光单元包括层叠设置的第一支撑层、偏光层和第二偏光层。
其中，偏光单元与第二胶层和第三胶层的位置关系，可参考示例二中偏光单元与第二胶层和第三胶层的位置关系的相关描述。
在一些示例中，步骤S240，制备第二复合棱镜膜的步骤还可以包括：在第二胶层上形成离型膜。
步骤五、将第二显示面板的非显示侧粘合在第二复合棱镜膜的第二胶层上。在一些示例中，剥离离型膜，暴露出第二胶层，将第二显示面板的非显示侧粘合在第二复合棱镜膜的第二胶层上。
下文继续介绍显示装置。参见图21～图24，其中，下文中的显示模组1表示全贴合的显示模组1，即全贴合的显示模组1可以是示例一的第一显示模组10，或者可以是示例二的第二显示模组20。
显示装置可以是例如无界屏的显示装置，无界屏的显示装置的非显示区的宽度小于等于1mm，使得边框极窄，光学膜片无法设置常规挂耳进行固定；在高温或者湿热条件下，光学膜片和扩散板的膨胀空间也十分有限，长期挤压会产生膜片褶皱等画面品质不良。例如显示装置中的直下式背光模组包括玻璃扩散板、以及贴附在玻璃扩散板上的光学膜片，可以解决光学膜片膨胀问题和固定空难的问题。
但是玻璃扩散板的价格较贵、光效较低，也需要玻璃扩散板也需要考虑固定问题，同时还需要考虑画面品质，使得背光模组的周边结构设计的十分复杂(例如需要多个不同宽度台阶，又例如需要多个导光条)，从而增加工艺难度、增加背光模组厚度和组装成本。此外玻璃扩散板较重，对稳定性要求都很高，很难做成超轻结构。
综上，显示装置中采用玻璃扩散板并不具备市场优势，需要新的技术方案解决此问题。
参见图21，显示模组1具有显示面11、背面12和连接显示面11和背面12的侧面13。框架4具有第一支撑面41；显示模组1的背面与第一支撑面41粘接。这样一来，显示模组1粘贴在框架4的一个接触位置(即第一支撑 面41)上，从而简化框架4的结构，以便于快速的将显示模组1与框架4的连接。第一支撑面41平行于显示面板所在平面，使得显示模组1较为水平的粘贴在框架4的第一支撑面41上。
示例性地，显示装置还包括第一粘贴层3，第一粘贴层3将显示模组1与第一支撑面41粘贴。例如，第一粘贴层3可以是具有缓冲性能，该第一粘贴层3可以为缓冲泡棉。又例如，第一粘贴层3可以是胶水。
在一些示例中，第一粘贴层3的颜色可以是例如黑色、灰色等遮光性较好的颜色；例如，第一粘贴层3可以是黑色的缓冲泡棉。第一粘贴层3的颜色还可以是例如白色等遮光性较差的颜色；例如，第一粘贴层3可以是透明的缓冲泡棉。
在一些实施例中，继续参见图21，框架4包括框本体43和第一遮蔽部42；框本体43具有第一支撑面41；第一遮蔽部42凸设在框本体43上，且暴露出第一支撑面41，并围绕显示模组1的侧面13设置。这样一来，第一遮蔽部42可以将显示模组1的侧面13遮蔽住，避免漏光。
在一些示例中，沿显示模组1的厚度方向上，第一遮蔽部42的尺寸大于或等于显示模组1的厚度。例如，沿显示模组1的厚度方向上，第一遮蔽部42的尺寸比显示模组1的厚度大于或等于0.5mm(例如0.5mm、1mm、1.5mm、2mm等)。
在一些示例中，显示装置还包括第二遮蔽部2，第二遮蔽部2粘贴在显示模组1的侧面上，第一遮蔽部42围绕第二遮蔽部2设置。这样一来，第二遮蔽部2可以防止显示模组1与第一遮蔽部42之间漏光。例如，第二遮蔽部2为双面胶的情况下，第二遮蔽部2可以粘贴在第一遮蔽部42与显示面板的侧面之间。又例如，第二遮蔽部2为缓冲泡棉的情况下，第二遮蔽部2可以粘贴在显示模组1上，第一遮蔽部4与第一遮蔽部2接触。
在一些可能实现的方式中，第二遮蔽部2可以是胶水或缓冲泡棉。例如，第二遮蔽部2可以是黑色的胶水或缓冲泡棉。
在另一些实施例中，参见图22，显示装置还包括第三遮蔽部6。框架整体(即图17中示出的框架整体，相比于图21中示出的框本体43，没有第一遮蔽部42)位于显示模组1的背面12远离显示面11的一侧。第三遮蔽部6粘贴在显示模组1的侧面13上。从而可以防止显示模组1的侧面13漏光。例如，第三遮蔽部6可以是黑色的缓冲泡棉或胶水。
在一些示例中，第三遮蔽部6从显示模组1的侧面13延展至第一支撑面41上。这样一来，可以避免第三遮蔽部6与第一支撑面41之间漏光。例如， 第三遮蔽部6在第一支撑部上的正投影与第一支撑面41存在重叠区域。
第一支撑面41的宽度小于显示面板的非显示区的宽度。这样一来，第一支撑面41不会挡住显示面板的显示区。在一些示例中，显示模组1包括黑矩阵图案。黑矩阵位于显示区，并延伸至非显示区；第一支撑面41的宽度小于黑矩阵中位于非显示区的部分的宽度。
在一些实施例中，显示装置还包括背光层5；背光层5设置在框架4上，且位于显示模组1的背面远离显示面的一侧。背光层5与显示模组1之间具有一个空气层，其中空气层不会改变光线的传播方向；使得背光层5发出的光可以通过空气层照射在显示模组1的背涂层上。由于显示模组1中的背涂层(例如第一显示模组中的第一背涂层，又例如，第二显示模组中的第二背涂层)的雾度大于或等于90％，使得光线经过该背涂层扩散，从而使得显示模组的显示画面更好。
示例性地，背光层5可以包括背板52和多个发光器件51。
发光器件51是在通电后可发光的器件。例如发光器件51可以是LED，微LED，OLED(Quantum Dot Light Emitting Diodes，量子点发光二极管)等，在此不做限制。作为示例，发光器件51可以是微型发光器件，该微型发光器件的尺寸可以参考微LED的尺寸。微LED包括亚毫米量级甚至微米量级的发光二极管，还可以包括尺寸更小的发光二极管。其中，亚毫米量级发光二极管也称为次毫米发光二极管(Mini Light Emitting Diode，简称：Mini LED)；Mini LED的尺寸(例如长度)可以为50微米～150微米，例如80微米～120微米，又如可以在100微米及以下。微米量级的发光二极管也称为微型发光二极管(Micro Light Emitting Diode，简称：Micro LED)；例如，Micro LED的尺寸(例如长度)可以小于50微米，例如10微米～50微米。
多个发光器件51设置在背板52上。多个发光器件51被配置为向显示模组1的背面12发光。
在一些示例中，背光层5还包括基板，基板可以为刚性基板。该刚性基板的材料可以为玻璃或PMMA(Poly Methyl Meth Acrylate，聚甲基丙烯酸甲酯)等。基板还可以为柔性基板。该柔性基板的材料可以为PET(Poly Ethylene Terephthalate，聚对苯二甲酸乙二醇酯)、PEN(Poly Ethylene Naphthalate Two Formic Acid glycol Ester，聚萘二甲酸乙二醇酯)、超薄玻璃或PI(Polyimide，聚酰亚胺)等。
多个发光器件51设置在基板上，基板设置在背板52上。多个发光器件51被配置为向远离基板的一侧发光。例如，多个发光器件51被配置为向显示 模组1的背面12发光。
框架4中远离第一支撑面41的一面固定在所述背板52上。例如框架4与背板52通过螺栓连接。
在一些示例中，背光层5可以是直下式结构。多个发光器件51例如阵列分布在背板52的上表面上；背板52的上表面与显示模组1的背面相对设置。
在另一些示例中，参见图24，背光层5可以是侧入式结构。背光层5还包括导光板53，多个发光器件51设置在框架4的侧面上。框架4的侧面与显示模组1的背面12交叉的面。发光器件51发出的经过导光板53传播至显示模组1的背面上。
在另一些实施例中，参见图23，显示装置还包括背光层5；背光层5设置在框架4上，且位于显示模组1的背面12远离显示面11的一侧。显示装置还包括设置在第二背光层5与显示模组1之间的扩散片8，使得背光层5发出的光可以通过扩散片8的散射后照射在显示模组1的背涂层上。由于显示模组中的背涂层(例如第一显示模组中的第一背涂层，又例如，第二显示模组中的第二背涂层)的雾度为35％～70％，使得光线经过该背涂层再扩散，从而使得显示模组的显示画面更好。
示例性地，背光层5可以包括背板52和多个发光器件51。框架4(例如是中框)中远离第一支撑面41的一面固定在所述背板52上。例如，背光层5可以是直下式结构，可参考上文中对背光层5可以是直下式结构的相关描述。又例如，背光层5可以是侧入式结构，可参考上文中对背光层5可以是侧入式结构的相关描述。不再赘述。
在一些示例中，显示装置还包括棱镜膜7。棱镜膜7设置于背光层5和显示模组1之间。这样一来，利用显示模组1中的棱镜层和棱镜膜7的结合，提高显示模组1的光效，参见表2，使得显示装置的亮度增益比为100％～120％(例如100％、105％、110％、115％、120％等)。
表2为现有显示装置与本实施例的显示装置的亮度增益比。
其中，表2中的非全贴合表示现有显示装置中显示面板与棱镜膜之间的之间空气层的固定方式。表2为显示模组为第一显示模组的情况下的显示装置。
DOP为雾度层、第一棱镜层、第一基材层、第一背涂层(雾度为35％～70％)；COP为雾度层、偏光增亮层、第一棱镜层、第一基材层、第一背涂层(雾度为35％～70％)；SOP为雾度层、偏光增亮层、第一棱镜层、第一基材层、第一背涂层(雾度为35％～70％)；VOP为雾度层、偏光增亮层、第一棱镜层、第一基材层、第一背涂层(雾度为35％～70％)；P为棱镜膜；其中，COP、SOP、VOP中的偏光增亮层的厚度依次增加。DBEF为偏光增亮膜。DOPB为雾度层、第一棱镜层、第一基材层、第一背涂层，其中，DOPB的雾度层的雾度大于DOP的雾度层的雾度。
由于显示装置的亮度提升了，因此可以降低背光层5中发光器件51的功率或者数量，达到节能降耗的作用，从而防止发光器件51的温度过高或者EEI不达标或级别过低。
此外，利用显示模组1中的棱镜层和棱镜膜7的结合，可以达到与现有显示装置中的偏光棱镜膜相同的作用，因此可以代替现有显示装置中的偏光棱镜膜，以节约了成本。
在一些示例中，棱镜膜7与显示模组1之间存在间隙。间隙为1.1mm～2.66mm(1.1mm、1.5mm、1.7mm、2mm、2.3mm、2.5mm、2.6mm、2.66mm等)。
在一些示例中，显示模组的中的棱镜层(例如，第一显示模组的中的第一棱镜层，又例如，第二显示模组的中的第二棱镜层)的延伸方向与棱镜膜7的延伸方向可以交叉(例如垂直)。
在一些示例中，显示装置还包括多个支撑柱9。支撑柱9的一端固定在背板52上，另一端与显示模组1的背面12接触。支撑柱9可以起到支撑显示模组1的作用。例如，该支撑柱9可以是弹跳式硅胶套支撑柱，这样一来，防止支撑柱9与显示模组1接触产生十字黑纹，并且在运输过程中还可以起到支撑显示模组1的作用。
以上，仅为本公开的具体实施方式，但本公开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公开揭露的技术范围内，想到变化或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应以权利要求的保护范围为准。
