Description

拼接显示模组以及显示装置 技术领域
本申请涉及显示器件技术领域，尤其涉及一种拼接显示模组以及显示装置。
 背景技术
随着平板显示技术的发展，各大厂商纷纷推出更大尺寸的显示面板，在由于受生产工艺的限制，显示面板的尺寸无法做到更大时，拼接显示装置应运而生。拼接显示装置具有大场景的显示效果，能够为用户带来身临其境的视觉体验，因此广泛应用于广告展示、宣传、展览等场合。但拼接显示装置模组与模组之间存在不能消除的物理拼缝，肉眼可见，因此会破坏显示画面的连续性，影响显示效果。
在对现有技术的研究和实践过程中，本申请的发明人发现，随着户外显示市场的快速发展，大尺寸、高解析度成为户外显示的发展方向。而传统的液晶显示面板（LCD）不仅成本低，解析度也高，但是作为拼接屏无法消除拼缝，影响视觉效果。而次毫米级发光二极管（Mini LED）面板和微型发光二极管（Micro-LED）面板目前在小间距上工艺仍不成熟，解析度不及LCD，且成本过高。因此，解决LCD拼接屏的拼缝问题成为目前急需解决的关键突破点。

请参考图1-图10，本申请实施例提供一种拼接显示模组，包括第一液晶显示模组10、第二液晶显示模组20、辅助显示面板30以及连接件40。
第一液晶显示模组10包括第一显示单元11和第一背光单元12，第一显示单元11设置于第一背光单元12上。
第二液晶显示模组20包括第二显示单元21和第二背光单元22，第二显示单元21设置于第二背光单元22上，第一显示单元11和第二显示单元21间隔设置，形成第一拼接缝1011。需要说明的是，第二液晶显示模组20和第二液晶显示模组20可以是相同的结构，因此，连接件40可以是和第一液晶显示模组10连接，也可以是和第二液晶显示模组20连接，均能实现对辅助显示面板30起到固定作用。
辅助显示面板30位于第一拼接缝1011内，辅助显示面板30的相对的两个端部分别与第一显示单元11和第二显示单元21连接。示例性地，辅助显示面板30的两个端部分别设置在第一显示单元11和第二显示单元21的边沿的表面，以最大程度地达到视觉上消除第一液晶显示模组10和第二液晶显示模组20之间形成的拼缝的效果。
具体地，结合图1和图9所示，第一显示单元11包括相对设置的第一彩膜基板103和第一阵列基板101，第一彩膜基板103和第一阵列基板101之间设置有第一液晶层102，第一彩膜基板103和第一阵列基板101的四周边缘设置第一框胶104，用于密封第一液晶层102。对应地，第二显示单元21包括相对设置的第二彩膜基板203和第二阵列基板201，第二彩膜基板203和第二阵列基板201之间设置有第二液晶层202，第二彩膜基板203和第二阵列基板201的四周边缘设置第二框胶204，用于密封第二液晶层202。其中，第一阵列基板101中和第二阵列基板201包括阵列设置的薄膜晶体管（TFT），分别用于驱动第一液晶层102和第二液晶层202工作。其中，辅助显示面板30的两个端部分别设置于第一彩膜基板103和第二彩膜基板203的表面，且辅助显示面板30在第一显示单元11的正投影覆盖第一框胶104，辅助显示面板30在第二显示单元21的正投影覆盖第二框胶204，由于第一显示单元11和第二显示单元21的框胶不能发光，因此通过将辅助显示面板30搭接在第一框胶104和第二框胶204上，从而可以最大程度地达到视觉上消除第一液晶显示模组10和第二液晶显示模组20之间形成的拼缝的效果。
其中，辅助显示面板30可以为有机发光二极管（OLED）显示面板，Mini LED显示面板或Micro LED显示面板等。如图2所示，其中，第一液晶显示模组10和第二液晶显示模组20的数量均可以为多个，对应地，第一液晶显示模组10和第二液晶显示模组20之间的第一拼接缝1011也会有多个，因此，辅助显示面板30的数量也可以设置多个。第一液晶显示模组10和第二液晶显示模组20之间交替排布，第一液晶显示模组10和第二液晶显示模组20可以呈“N×N”矩阵式分布，例如为“2×2”矩阵式分布、“1×4”矩阵式分布、“6×6”矩阵式分布等。
如图4所示，连接件40的一端与辅助显示面板30连接，连接件40的另一端与第一背光单元12连接。其中，连接件40可以是板状结构、网状结构或柱状结构等，通过将连接件40设置为板状结构可以增加连接件40和第一背光单元12之间的接触面积，从而可以更好地提高辅助显示面板30和第一背光单元12之间的结构稳定性。连接件40可以为塑料件，塑料件具有良好的绝缘性和可机加工性，便于实现连接件40的多样化结构设计。可以理解的是，连接件40不以塑料件为限，连接件40也可以是其他材质，例如，连接件40可以为铝合金件、不锈钢合金件等金属件。
本申请实施例的拼接显示模组，在第一液晶显示模组10的第一显示单元11和第二液晶显示模组20的第二显示单元21之间形成的第一拼接缝1011内，设置辅助显示面板30，辅助显示面板30的相对的两个端部分别与所述第一显示单元11和所述第二显示单元21连接，使得第一拼接缝1011处也能实现发光显示，从而视觉上消除第二液晶显示模组20和第二液晶显示模组20之间形成的拼缝，同时，在辅助显示面板30和第一背光单元12之间设置连接件40，以此对辅助显示面板30起到固定作用，避免辅助显示面板30与第一液晶显示模组10或第二液晶显示模组20之间发生相对移动，避免辅助显示面板30偏移，从而可以增强拼接显示模组的结构稳定性，进而有利于提升显示效果。
在一些实施例中，如图2所示，拼接显示模组还包括显示控制装置70。显示控制装置70与第一液晶显示模组10、第二液晶显示模组20和辅助显示面板30电连接，显示控制装置70用于控制第一液晶显示模组10、第二液晶显示模组20和辅助显示面板30同步显示，以使第一液晶显示模组10、第二液晶显示模组20和辅助显示面板30共同显示完整画面。
其中，显示控制装置70可以包括视频处理卡。通过视频处理卡将图像分割为由第一显示单元11、第二显示单元21的显示部分和辅助显示面板30的显示的部分，然后通过驱动器驱动第一显示单元11、第二显示单元21的显示部分和辅助显示面板30同步显示，从而达到消除边框视觉影响的目的。
在一些实施例中，如图3所示，第一显示单元11具有第一出光面111，第一出光面111背向第一背光单元12设置。相应地，第二显示单元21具有第二出光面211，第二出光面211背向第二背光单元22设置。辅助显示面板30包括相背设置的第三出光面311和背光面314。连接件40设置于背光面314上，将连接件40设置于背光面314上，从而不影响出光，以此保证拼接显示模组的显示效果。
在一些实施例中，辅助显示面板30的两端分别搭接于所述第一出光面111和第二出光面211的表面的边沿。由于第一出光面111和第二出光面211的表面的边沿不发光，因此可以最大程度地达到视觉上消除第一液晶显示模组10和第二液晶显示模组20之间形成的拼缝的效果。
在一些实施例中，连接件40可以为板状连接件40，此时，如图1所示，连接件40的宽度可以小于第二拼接缝1012的宽度，即连接件40的一侧面可以与第一背光单元12抵接，相对的另一侧面与第二背光单元22间隔设置，从而可以减小连接件40的厚度，有利于整个拼接显示模组轻量化的实现。当然，如图3所示，连接件40的宽度可以等于第二拼接缝1012的宽度，即，连接件40相对的两个侧面分别与第一背光单元12和第二背光单元22抵接，增大连接件40和辅助显示面板30之间的接触面积，从而进一步提高辅助显示面板30与第一液晶显示模组10或第二液晶显示模组20之间的结构稳定性。
在一些实施例中，如图5所示，连接件40包括相互交叉设置的第一连接部41和第二连接部42，具体地，第一连接部41和第二连接部42可以相互垂直设置，示例性地，第一连接部41沿水平方向X设置，第二连接部42沿竖直方向Y设置，第一连接部41的法线和背光面314的法线同向设置，对应地，背光面314也是沿水平方向X设置，第一连接部41与背光面314粘接。其中，第一连接部41和背光面314两个面可以相互平行设置，第一连接部41和第二连接部42均呈平板结构，第一连接部41和第二连接部42之间可以呈类似倒“L”型结构设置，第一连接部41和第二连接部42之间一体成型设置，以此保证连接件40的结构强度，此时，第二连接部42与第一背光单元12抵接且第二连接部42与第二背光单元22间隔设置，从而在第一连接部41增大背光面314和连接件40之间的接触面积的同时，可以节约支撑件的使用材料，有利于拼接显示模组轻量化的实现。
在一些实施例中，如结合图1和图6所示，第一背光单元12和第二背光单元22间隔设置，形成第二拼接缝1012，连接件40部分置于第一拼接缝1011内，部分置于第二拼接缝1012内。其中，第一显示单元11在第一背光单元12上的正投影面积小于第一背光单元12的正投影面积，第一显示单元11的边沿和第一背光单元12的边沿形成一台阶部13，第二显示单元21在第二背光单元22上的正投影面积小于第二背光单元22的正投影面积，从而第一拼接缝1011的缝隙大于第二拼接缝1012的缝隙。通过将连接件40部分置于第一拼接缝1011内，部分置于第二拼接缝1012内，便于将连接件40安装在第一显示单元11的侧面，提高安装效率。
在一些实施例中，如图6所示，连接件40和第一背光单元12定位配合且通过紧固件51固定相连，紧固件51穿设于定位组件52，从而将第一液晶显示模组10和辅助显示面板30固定，从而便于保证第一液晶显示模组10和辅助显示面板30的装配精度，紧固件51可以保证定位组件52可靠配合，同时方便了紧固件51的快速安装，有利于提升第一液晶显示模组10和辅助显示面板30的组装效率。紧固件51可以为螺栓或胶粘层等能起到紧固作用的部件。
在一些实施例中，请继续参考图6，紧固件51可以为螺纹紧固件，以紧固件51为螺栓为例，定位组件52包括第一安装孔521和第二安装孔522。其中，第一安装孔521设置于连接件40上，第二安装孔522设置于第一背光单元12朝向第二背光单元22的一面，紧固件51穿设于第一安装孔521和第二安装孔522以将连接件40和侧壁连接。紧固件51还可以包括螺栓和螺母，螺栓和螺母螺纹配合，此时第一安装孔521和第二安装孔522均为通孔；或者，第一安装孔521的壁面和/或第二安装孔522的壁面设置螺纹，紧固件51与第一安装孔521和/或第二安装孔522螺纹配合将从而将第一液晶显示模组10和辅助显示面板30固定相连。
在一些实施例中，如图7所示，定位组件52还可以包括第三安装孔524和定位凸起523，其中第三安装孔524设置于连接件40或第二背光单元22中的其中一个上，对应地，定位凸起523设置于连接件40或第二背光单元22中的其中另一个上，第三安装孔524和定位凸起523相适配。示例性地，第三安装孔524可以设置于连接件40上，定位凸起523设置于第二背光单元22上。其中，定位凸起523可以是柱状结构或锥状结构，以定位凸起523呈柱状结构为例，定位凸起523可以是圆柱或三棱柱、四棱柱、五棱柱等棱柱结构，在此不对定位凸起523的结构做具体限制。对应地，第三安装孔524也可以是圆孔、方孔或其他多边孔等，在此亦不做具体限制。当然，可以理解，第三安装孔524也可以设置于第二背光单元22上，定位凸起523设置于连接件40上。
通过第三安装孔524和定位凸起523的设置，可以使得在第一液晶显示模组10和辅助显示面板30通过连接件40实现固定连接后，再将第二液晶显示模组20安装到连接件40上时，第三安装孔524和定位凸起523可以快速实现定位，从而提高安装效率。
在一些实施例中，结合图3和图8所示，第一出光面111、第二出光面211和第三出光面311可以齐平设置，从而减少不同出光面的不同角度的显示差异，提升拼接显示模组的显示均一性。
其中，请参考图9，当连接件40相对的两个侧面分别与第一背光单元12和第二背光单元22抵接时，第一背光单元12、第二背光单元22和连接件40之间可以采用粘接的方式连接，即紧固件51可以为粘接层511，其中，粘接层511的材料为光学透明粘接材料，例如可以是OCA(Optically Clear Adhesive)光学胶、SCA光学胶、离子性中间膜(Surper Safe Glass，SGP)、液态光学胶LOCA(Liquid Optical Clear Adhesive)等，在此不对粘接层511的材料做具体限制。
具体地，辅助显示面板30包括相对的第一侧面112和第二侧面212。第一显示单元11与第一侧面112通过光学胶512粘接，第一显示单元11与第二侧面212通过光学胶512粘接。其中，光学胶512例如可以是OCA(Optically Clear Adhesive)光学胶、SCA光学胶、离子性中间膜(Surper Safe Glas，SGP)、液态光学胶LOCA(Liquid Optical Clear Adhesive)等。通过第一侧面112和第二侧面212实现第一显示单元11和第二显示单元21分别与辅助显示面板30连接，从而可以对辅助显示面板30进一步实现限位作用，从而防止辅助显示面板30移位，有利于提高拼接显示模组的显示效果。
在一些实施例中，如图10所示，第一背光单元12还包括第一背板121。第一背板121包括第一底板1211和由所述第一底板1211的边缘弯折形成的第一侧板1212，连接件40与第一侧板1212连接。其中，第一背光单元12由下往上依次包括第一背板121、位于第一背板121侧边上的第一激发光源124、第一反射片122、第一导光板123、第一光学膜片125、第一胶框126，置于第一胶框126之上的第一显示单元11。
对应地，第二背光单元22还包括第二背板221。第二背板221包括第二底板2211和由所述第二底板2211的边缘弯折形成的第二侧板2212，连接件40可以与第二侧板2212连接或与第二侧板2212间隔设置。其中，第二背光单元22由下往上依次包括第二背板221、位于第二背板221侧边上的第二激发光源224、第二反射片222、第二导光板223、第二光学膜片225、第二胶框226，置于第二胶框226之上的第二显示单元21。
由于在第一背光单元12中，第一背板121可以起到对第一显示单元11的支撑固定作用，结构稳定性较好，而且第一背板121的第一侧板1212背向第一激发光源124的一面不会设置其他结构，从而将连接件40设置在第一侧板1212上可以保证连接稳定性的同时充分利用第一液晶显示模组10的空间，结构紧凑。
以辅助显示面板30是顶发光OELD显示面板为例，辅助显示面板30可以包括自上而下依次设置的衬底31、驱动电路层32、有机发光层33以及封装层34。连接件40可以与衬底31连接，从而不影响OLED显示面板的出光显示。
为了更好地实施本申请的拼接显示模组，本申请实施例还提供一种显示装置，所述显示装置包括所述的拼接显示模组。由于该显示装置具有上述拼接显示模组，因此具有全部相同的有益效果，本实施例在此不再赘述。本申请实施例对于所述显示装置的适用不做具体限制，其可以是电视机、笔记本电脑、平板电脑、手机、电影屏、舞台屏、户外屏、车载显示、广告灯屏等任何具有显示功能的产品或部件。
