相关技术中的框体101由背板、中框、外框等组装而成，在本公开实施例提供的上述显示装置中，提供了一体设置的框体101，由此减少了框体101本身的装配等，并且通过一体设置的框体101可以同时实现对背光源102、光学组件103和三维显示组件104的固定，简化了显示装置的整体布局，提高了显示装置的可靠性。
在一些实施例中，在本公开实施例提供的上述显示装置中，框体101的材料可以包括导热材料，例如铝金属、铝合金等，以提高框体101的散热性能，增加传热效率，可以快速把热量导到环境中，并且还可以尽可能地减小框体101的本身重量。在一些实施例中，可通过数控机床(CNC)加工或者铸铝 实现框体101的量产，同时具有非常好的表面处理成型能力，能实现细腻的外观品质。可选地，背光源102可以与本体1011贴合固定，以利于将背光源102产生的热量直接导入框体101进行散热。在一些实施例中，为避免背光源102可能烫伤光学组件103，本公开中可设置背光源102与光学组件103之间具有间距，而非接触设置。可选地，光学组件103包括反射片1031、导光板1032和光学膜材1033(包括在导光板1032远离反射片1031的一侧层叠设置的扩散膜、棱镜膜和增亮膜)等，以使背光的亮度充足且均匀分布。
在一些实施例中，本公开的背光源102可以为矩阵光源，矩阵光源中的灯珠可以为发光二极管(LED)，例如微型发光二极管(Mini LED、Micro LED等)。亚毫米量级甚至微米量级的微型发光二极管和有机发光二极管(OLED)一样属于自发光器件。其与有机发光二极管一样，有着高亮度、超低延迟、超大可视角度等一系列优势。并且由于无机发光二极管发光是基于性质更加稳定、电阻更低的金属半导体实现发光，因此它相比基于有机物实现发光的有机发光二极管来说，有着功耗更低、更耐高温和低温、使用寿命更长的优势。且在微型发光二极管作为背光源102时，能够实现更精密的动态背光效果，在有效提高屏幕亮度和对比度的同时，还能解决传统动态背光在屏幕亮暗区域之间造成的眩光现象，优化视觉体验。
在一些实施例中，在本公开实施例提供的上述显示装置中，如图1a、图1b、图2a和图2b所示，三维显示组件104可以包括保护盖板1041、以及位于保护盖板1041朝向光学组件103一侧的液晶显示屏1042和液晶透镜屏1043，其中，液晶显示屏1042和液晶透镜屏1043位于容置空间r内，保护盖板1041与侧壁1012固定，可选地，保护盖板1041的边缘可通过一圈胶体G贴合在侧壁1012上。
在一些实施例中，可采用钢化玻璃作为保护盖板1041，以使得保护盖板1041具有较大的强度和透光率。液晶显示屏可以为扭转向列(Twisted Nematic,TN)型液晶显示屏，也适用于高级超维场开关(Adwanced Dimension Switch,ADS)型液晶显示屏、高开口率-高级超维场开关(High-Adwanced Dimension Switch,HADS)型液晶显示屏、平面内开关(In-Plane Switch,IPS)型液晶显示屏等。在一些实施例中，如图1a、图1b、图2a和图2b所示，可设置液晶透镜屏1043位于液晶显示屏1042与保护盖板1041之间；当然，在一些实施例中，也可以将液晶显示屏1042设置于液晶透镜屏1043与保护盖板1041之间，在此不做限定。可选地，为提高光学组件103提供光线的均匀性，可使得光学组件103与三维显示组件104之间具有间隙，该间隙还可以保证光学组件103在高温下有足够的膨胀空间，防止光学组件103可能因高温膨胀而挤压三维显示组件104，影响显示效果。

在一些实施例中，在本公开实施例提供的上述显示装置中，第一覆晶薄膜105、第二覆晶薄膜106、第三覆晶薄膜107的长度不同，以使得第一控制电路板108、第二控制电路板109和第三控制电路板110在本体1011远离容置空间r的一侧可以错开设置，避免相互干扰。可选地，如图7a和图7b所示，第二控制电路板109和第三控制电路板110可以在本体1011上并排平行设置，且第三控制电路板110位于第二控制电路板远离镂空结构K的一侧，换言之，第二控制电路板109相对于第三控制电路板110靠近容置空间r的边缘设置，第三控制电路板110相对于第二控制电路板109靠近容置空间r的中间区域设置；第一控制电路板108固定于第二控制电路板109远离本体1011的一侧，在一些实施例中，第一控制电路板108可通过转接环固定在第二控制电路板109上，应当理解的是，转接环的位置应避开第一控制电路板108与第二控制电路板109上的各元器件。
在一些实施例中，在本公开实施例提供的上述显示装置中，如图2a和图2b所示，还可以包括屏蔽罩111，屏蔽罩111位于第一控制电路板108、第二控制电路板109和第三控制电路板110远离本体1011的一侧且与本体1011固定，屏蔽罩111在本体1011上的正投影覆盖第一控制电路板108在本体1011上的正投影、第二控制电路板109在本体1011上的正投影、以及第三控制电路板110在本体1011上的正投影。这样可以通过屏蔽罩111对显示相关的第一控制电路板108、第二控制电路板109和第三控制电路板110进行电磁屏蔽和保护。
在一些实施例中，在本公开实施例提供的上述显示装置中，如图1a、图1b、图2a、图2b、图7a和图7b所示，还可以包括摄像集成板112，该摄像集成板112位于容置空间r内，摄像集成板112在本体1011上的正投影位于镂空结构K在本体1011上的正投影内，且摄像集成板112与邻近镂空结构K的侧壁1012固定，可选地，摄像集成板112通过固定结构件112’固定在侧壁1012上。摄像集成板112可理解为摄像头组件，在裸眼3D显示时摄像集成板112可以实时根据人眼的位置调整画面进行智能显示。
在一些实施例中，在本公开实施例提供的上述显示装置中，如图1a、图1b、图2a、图2b、图7a和图7b所示，还可以包括第四控制电路板113，第四控制电路板113固定在屏蔽罩111远离本体1011的一侧，且第四控制电路板113与摄像集成板112电连接，以通过第四控制电路板113为摄像集成板112提供电信号。可选地，第四控制电路板113可通过螺柱等固定在屏蔽罩111上。第四控制电路板113可以具有摄像头识别和处理芯片1131。
在一些实施例中，在本公开实施例提供的上述显示装置中，如图5a和图7a所示，本体1011在设置摄像集成板112的位置可以朝向远离容置空间r的方向凸出设置，以将摄像集成板112设置在本体1011的该凸出位置，使得产品结构较紧凑。当然，在一些实施例中，还可以将摄像集成板112所在侧的本体1011边缘整体平齐设置(如图5b和图7b)，在此不做限制。应当理解的是，在摄像集成板112所在侧的本体1011边缘整体平齐设置的情况下，摄像集成板112的长度可以小于其所在侧的本体1011的边缘长度，也可以与本体1011的边缘长度大致相同(如图5b和图7b所示)。在本公开中“大致相同”可理解为相同或在因制作、测量等因素造成的合理误差范围(例如±5％)内。
在一些实施例中，在本公开实施例提供的上述显示装置中，如图2a和图2b所示，还可以包括遮光件114，该遮光件114位于摄像集成板112远离保护盖板1041的一侧、以及固定摄像集成板112的侧壁1012与光学组件103之间，使得遮光件114可防止下侧环境光和旁边光学组件103的光线照射至摄像集成板112而影响摄像集成板112对人眼位置进行追踪成像。可选地，遮光件114固定在集成电路板112与屏蔽罩111之间。

在一些实施例中，在本公开实施例提供的上述显示装置中，如图1a、图1b、图2a和图2b所示，还可以包括散热板116，该散热板116固定在系统电路板115远离本体101的一侧，以利于提升系统电路板115上主芯片1551的散热效率。可选地，散热板116可采用铝金属、铝合金等导热性好的材料制作，且铝金属、铝合金材质的散热板116的重量较轻，利于减小显示装置的整体重量。
在一些实施例中，在本公开实施例提供的上述显示装置中，如图1a、图1b、图2a和图2b所示，还可以包括外壳117，该外壳117位于散热板116和屏蔽罩111远离本体1011的一侧，且外壳117与本体1011远离容置空间r一侧的边缘固定，以通过外壳117对本体1011远离容置空间r一侧的第一控制电路板108、第二控制电路板109、第三控制电路板110、第四控制电路板113、系统电路板115等进行保护。可选地，外壳117可采用铝合金等导热材质，以使得显示装置整体都提高了热源的传导效率，并使得外壳117较轻。应当理解的是，因为外壳117与本体1011远离容置空间r一侧的边缘固定，所以外壳117的底部(与本体1011正对设置)形状可以与本体1011的形状类似，基于此，本体1011在摄像集成板112处凸出设置的情况下，外壳117也可以相应地凸出设置，以匹配本体1011的形状，增强外壳117与本体1011的连接稳定性。
在一些实施例中，在本公开实施例提供的上述显示装置中，如图7a、图7b、图8a、图8b和图9所示，还可以包括按键组件118，该按键组件118位于外壳117与本体1011围成的空间内，且按键组件118固定在外壳117上。可选地，外壳117包括按键孔H，按键组件118包括图标按键板1181和按键控制板1182，图标按键板1181包括用图标直接做成的按键，即图标按键(例如开关键、音量键)，图标按键与按键孔H对应设置，按键控制板1182电连接在图标按键板1181远离外壳117的一侧。这样可以使得图标按键与其对应的按键孔H在同一高精度上去匹配，满足较好的组装方式，保证其控制手感。 可选地，如图1a所示，还可以在按键组件118上设置补强板1183，以增强按键组件118的强度。

在一些实施例中，在本公开实施例提供的上述显示装置中，如图1a、图1b、图2a、图2b、图7a、图7b、图10a、图10b、图11a和图11b所示，还可以包括至少一个涡轮风扇120，涡轮风扇120连接在散热板116朝向外壳117的一侧，使得系统电路板115的主芯片1151发出的热量，可经散热板116导热和涡轮风扇120吸热，进行降温，避免主芯片1151过热而损坏。

在一些实施例中，在本公开实施例提供的上述显示装置中，如图1a、图1b、图2a和图2b所示，外壳117包括至少一个壁挂孔h，壁挂孔h在本体1011上的正投影位于系统电路板115在本体1011上的正投影内，且壁挂孔h在本体1011上的正投影与涡轮风扇119在本体1011上的正投影错开设置。壁挂孔h可以实现不同支架的安装和选型，定制化不同的应用场景的支架，如手术室，游戏厅等，具有较高的通用性。可选地，如图8a和图8b所示，壁挂孔h为多个(例如四个)的情况下，多个(例如四个)壁挂孔h可以均匀分布在外壳117的中部位置，以减小支撑的应力集中。
在一些实施例中，在本公开实施例提供的上述显示装置中，如图2a所示，系统电路板115和散热板116可以包括与壁挂孔h正对设置的通孔h’，使得支架可通过贯穿设置的壁挂孔h和通孔h’安装在本体1011上；或者，如图2b所示，还可以包括壁挂转接件122，壁挂转接件122可以连接在本体1011与壁挂孔h邻近的外壳117之间，使得支架可通过壁挂孔h和壁挂转接件122固定在本体1011上。可选地，如图8a所示，外壳117在包围壁挂孔h的区域(例如外壳117与本体1011相对而置的底部的中部位置)朝向容置空间r的方向凹陷设置，以在凹陷位置容纳底座等支架。当然，在一些实施例中，如图8b所示，外壳117的底部(与本体1011相对而置)也可以平坦设置。
需要说明的是，本公开可以通过6种方式加强框体101本身的强度，如图5a、图5b、图6a和图6b所示，①是设置本体1011的厚度取值在2.5mm～3.5mm之间，以保证框体101的平整度和强度，②是在框体101背面(相当于本体1011远离容置空间r的一侧)的四个边缘有环形限位筋RL，防止其整体翘曲同时作为外壳117的精度限位特征；③是在框体101背面(相当于本体1011远离容置空间r的一侧)设置与环形限位筋RL同高的凸包，并在凸包上进行孔位连接系统相关板件(例如凸包上可连接固定各电路板的螺柱)；④是支架铆接转接螺柱(与外壳117上的壁挂孔h对应设置)，四个均匀分布在本体1101的中部位置减小支撑的应力集中；⑤是在本体1101下边缘开设镂空结构K(该镂空结构K可为图5a所示在下侧中部位置自左而右延伸的开槽，也可以为图5b所示在下 侧贯穿左右的开槽)，在CNC加工时可以通过该镂空结构K较好的释放材料应力，减小变形量；⑥是侧壁1012的厚度较本体1011的厚度，强化到5.5mm～6.5mm，进一步的保证一体化框体101的平整度和强度。
在一些实施例中，本公开还提供了上述显示装置不同角度的视图，如图12a、图12b、图13a和图13b所示，由这些视图可以看出，为了实现整体外观的视觉薄化，同时减小其整体的重量，将光场显示部分的模组(包括三维显示组件104、光学组件103、背光源102和框体101)和被外壳117包围的整机系统在视觉上分离，但在结构上一体化。在一些实施例中，在视觉上，其三维显示组件104、包括光学组件103、背光源102和框体101的背光模组层和整机系统在材料上和结构上看，视觉上有较明显的差别。
另外，如图1a和图1b所示，本公开为实现显示装置的一体化，在组装显示装置时可以将各大组件进行分类模块化，其中提供③所示的三维显示组件104，该三维显示组件104包括保护盖板1041、液晶显示屏1042和液晶透镜屏1043为一整体组件，其与光学组件103、背光源102、框体101、第一覆晶薄膜105、第二覆晶薄膜106、第三覆晶薄膜107、第一控制电路板108、第二控制电路板109和第三控制电路板110组成完整的显示组件，之后将②所示的所有系统组件包括智能摄像组件(包括摄像集成板112、第四控制电路板113和遮光件114)，按键组件118(包括图标按键板1181和按键控制板1182)，系统板组件(包括系统电路板115、散热板116)，风扇组件(包括涡轮风扇120和直吹风扇121)等完成整体系统组装，最后将外壳117与框体101进行锁附实现装置的一体化组装成①所示的显示装置。
