有鉴于此，本申请提供一种曲面显示面板的贴合方法，解决了现有的贴合方法容易产生膜层间的翘起，从而导致贴合后产生气泡的问题。
本申请一实施例提供的一种曲面显示面板的贴合方法，所述曲面显示面板包括引导膜、膜层结构、盖板，所述贴合方法包括：将引导膜贴合在膜层结构的一侧；沿靠近所述膜层结构的方向拉拽所述引导膜，使所述膜层结构的边缘具有预设弧度；所述引导膜沿靠近盖板的方向移动，所述引导膜与所述盖板部分接触；通过贴合机构对所述膜层结构和所述引导膜挤压，将所述引导膜全部贴合在所述盖板上；以及除掉所述引导膜的四周边缘部分，使所述引导膜的四周与所述膜层结构的四周齐平。
本申请实施例提供的一种曲面显示面板的贴合方法，该贴合方法包括将引导膜贴合在膜层结构的一侧；沿靠近所述膜层结构的方向拉拽所述引导膜，使所述膜层结构的边缘具有预设弧度；引导膜沿靠近所述盖板的方向移动，引导膜与盖板部分接触；通过贴合机构对所述膜层结构和所述引导膜挤压，将所述引导膜全部贴合在所述盖板上；以及除掉所述引导膜的四周边缘部分，使所述引导膜的四周与所述膜层结构的四周齐平。通过使用引导膜对膜层结构在靠近膜层结构的方 向上施加压力，膜层结构的各个膜层之间均承受压力，因此膜层结构的各个膜层之间贴合的更加紧密，更容易保持膜层结构之间的相对位置，因此不会产生变形和翘起等问题，且由于引导膜对膜层结构施加压力，使膜层结构具有预设弧度，能够保证将引导膜及膜层结构贴合在盖板上时，引导膜的边缘部分和盖板的边缘部分不先接触，因此不会由于引导膜的边缘部分和盖板的边缘部分先接触后形成密闭的空间，导致贴合过程中气体的存在，从而减少了贴合过程中气泡的产生。

实施本发明的方式
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作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。
如图1所示，曲面显示面板包括引导膜、膜层结构、盖板，该曲面显示面板的贴合方法包括：
步骤01：将引导膜3贴合在膜层结构2的一侧。其中，曲面显示面板可包括膜层结构2和盖板4，在工艺生产中需要将膜层结构2贴合在盖板4上，膜层结 构2包括至少一个膜层，该膜层可以为屏体、触控层或偏光层等。引导膜3的作用为引导膜层结构2进行贴合，将引导膜3贴合在膜层结构2的一侧，能够防止引导膜3和膜层结构2之间在贴合过程中由于受力而出现位置的滑移，影响贴合的精准度。
膜层结构2可为一层膜层，也可以为多层膜层，膜层结构2的具体结构可根据实际的产品进行调整，本申请对膜层结构2的具体结构不作限定。
引导膜3和膜层结构2间可通过光学胶进行贴合，还可通过其他具有黏性的物质进行贴合，引导膜3和膜层结构2之间采用何种物质进行贴合可根据实际的需求进行选择，本申请对引导膜3和膜层结构2之间采用何种物质进行贴合不作限定。
步骤02：(如图2所示)沿靠近膜层结构2的方向拉拽引导膜3，使膜层结构2的边缘具有预设弧度。沿靠近膜层结构2的方向拉拽引导膜3，使引导膜3对膜层结构2在施加压力，膜层结构2的各个膜层之间均承受压力，因此膜层结构2的各个膜层之间贴合的更加紧密，膜层结构2的受力变为压力，因此更容易保持膜层结构2的各膜层之间的相对位置，因此不会产生变形和翘起等问题。且由于沿靠近膜层结构2的方向拉拽引导膜3，使引导膜3对膜层结构2施加压力，从而使膜层结构2的边缘处形成一预设弧度，由于引导膜3贴合在膜层结构2上，所以引导膜3上与膜层结构2边缘处对应的位置上也具有预设弧度，该预设弧度能够保证将引导膜3及膜层结构2贴合在盖板4上时，引导膜3的边缘部分和盖板4的边缘部分不先接触，因此不会由于引导膜3的边缘部分和盖板4的边缘部分先接触后形成密闭的空间，导致贴合过程中气体的存在，从而减少了贴合过程中气泡的产生。
沿靠近膜层结构2的方向拉拽引导膜3可包括：使用夹爪6夹住引导膜3的四周边缘部分，向靠近膜层结构2的方向移动夹爪6。通过夹爪6对引导膜3施加的向靠近膜层结构2方向的拉力，使引导膜3对膜层结构2施加压力，使用夹爪6夹住并拉拽引导膜3，能够更加牢固，防止在拉拽的过程中出现夹爪6和引导膜3脱离的问题。
使用夹爪6夹住引导膜3可以使用多个夹爪6，均匀的分布在引导膜3的四周边缘，使用多个夹爪6夹住引导膜3的四周边缘，同时对引导膜3沿靠近膜层结构2的方向移动，可以使引导膜3的各部位所承受的拉力均匀，从而保证贴合表面的平整，提高产品良率。使用夹爪6的数量可根据实际的产品尺寸进行调整，本申请对夹爪6的数量不作限定。
预设弧度的具体大小可根据盖板4的曲面形状进行设定，只要满足预设弧度需要小于盖板4的弧度，此时引导膜3的边缘部分不会先和盖板4的边缘部分接触形成密闭的空间，导致贴合过程中气体的存在，本申请对预设弧度的具体大小不作限定。
步骤03：(如图3所示)引导膜3沿靠近盖板4的方向移动，引导膜3与盖板4部分接触。将引导膜3沿盖板4的方向移动的同时，可继续拉拽引导膜3对膜层结构2施加压力，也就是说，此时引导膜3同时承受沿靠近盖板4方向的力和靠近膜层结构2方向的力，靠近盖板4方向的力时引导膜3向靠近盖板4的方向运动，靠近膜层结构2方向的力使引导膜3对膜层结构2施加压力，使膜层结构2边缘具有预设弧度，靠近盖板4方向的力大于靠近膜层结构2方向的力。将引导膜3的非预设弧度处与盖板4的非曲面部分相接触，能够保证引导膜3的边缘部分和盖板4的边缘部分不先接触，因此不会由于引导膜3的边缘部分和盖板4的边缘部分先接触后形成密闭的空间，导致贴合过程中气体的存在，从而减少了贴合过程中气泡的产生。
引导膜3和盖板4的部分接触的面积可根据实际的情况进行调整，引导膜3和盖板4的部分接触主要是将引导膜3即其承载的膜层结构2拉拽到预设弧度，以及后续引导膜3承载着膜层结构2与盖板4接触，本申请对引导膜3和盖板4的部分接触的具体面积不作限定。
步骤04：通过贴合机构1对膜层结构2和引导膜3的挤压，将引导膜3全部贴合在盖板4上。贴合机构1可从膜层结构2远离引导膜3的一侧对膜层结构2施力。膜层结构2可具有弹性形变，在施力过程中，由于贴合机构1自身的弹性形变将膜层结构2和引导膜3完全挤压在盖板4内，将引导膜3全部贴合在盖板 4上。采用上述方法将膜层结构2和引导膜3贴合在盖板4上，可使贴合更加牢固，防止气泡的产生。
贴合机构1可以为滚轮，也可以为硅胶块，贴合机构1的具体类型可根据实际的产品进行选择，本申请对贴合机构1的具体类型不作限定。
可以采用光学胶的方式将盖板4贴合在引导膜3上，也可以采用其他具有黏性的材质将盖板4贴合在引导膜3上，采用何种材质的物质将盖板4和引导膜3贴合可根据实际的需求进行选择，本申请对将采用何种物质贴合盖板4和引导膜3不作限定。
步骤05：(如图4所示)除掉引导膜3的四周边缘部分，使引导膜3的四周与膜层结构2的四周齐平。由于需要对引导膜3进行拉拽，所以引导膜3的表面积要大于膜层结构2的表面积，多出的表面积可位于引导膜3的四周边缘处，引导膜3的四周边缘部分用于人手或机械设备对引导膜3进行固定并施力，当完成步骤03后，可以除掉引导膜3的四周边缘部分，以使引导膜3的四周与膜层结构2的四周齐平，保证曲面显示面板的形状完整。
除掉引导膜3四周边缘部分可以为撕除或切除等方式，本申请对采用何种方式除掉引导膜3四周边缘部分不作限定。
本申请一实施例中，贴合机构1可为仿形压头，步骤02沿靠近膜层结构2的方向拉拽引导膜3，使引导膜3具有预设弧度包括：将仿形压头与膜层结构2接触后沿靠近膜层结构2的方向拉拽引导膜3，使引导膜3具有预设弧度。仿形压头是具有和盖板4形状相仿的压头，将贴合引导膜3的膜层结构2与仿形压头相接触，由于仿形压头的形状和盖板4的形状相似，沿靠近膜层结构2的方向拉拽引导膜3，可以使引导膜3具有和盖板4形状相似的预设弧度，进而使膜层2结构具有和盖板4形状相似的预设弧度，因此更利于贴合，提高贴合效果。
预设弧度可以和盖板4的弧度相同，也可以小于盖板4的弧度，本申请对预设弧度的大小不作限定。
本申请一实施例中，引导膜3可以为偏光片，将偏光片贴合在膜层结构2一侧，沿靠近所述膜层结构2的方向拉拽偏光片，使偏光片对膜层结构2施加压力， 使膜层结构2和偏光片的边缘具有预设弧度，除掉所述偏光片的四周边缘部分，使偏光片的四周与膜层结构2的四周齐平，使用偏光片作为引导膜3，不会增加显示面板的厚度，不会影响显示面板的显示效果，且撕除部分的偏光片也可用于小屏设备如智能手环、智能手表等，因此不会造成资源的浪费。引导膜3还可以为新增的膜层，此时引导膜3可以为高温聚酯薄膜，该高温聚酯薄膜和盖板4具有相同的折射率，因此不会影响显示面板的显示效果。
引导膜3可以为偏光片或新增膜层，其他功能模组也可以作为引导膜3，使用何种膜层作为引导膜3可以根据实际的生产和需求进行选择，本申请对使用何种膜层作为引导膜3不作限定。
本申请一实施例中，当引导膜3为新增膜层时，膜层结构2还包括偏光片。当膜层结构2包括偏光片时，步骤01中将所述将引导膜3贴合在膜层结构2的一侧包括：将引导膜3贴合在偏光片的一侧。将引导膜3贴合在偏光片上，能够防止当引导膜3对偏光片施加压力时，出现引导膜3和偏光片之间滑动导致贴合位置偏移的问题，从而提高产品的良率。
上述贴合均可采用光学胶进行贴合，也可采用其他具有黏性的物质进行贴合，采用何种物质进行贴合可根据实际的产品需求进行调整，本申请对偏光片和引导膜之间采用何种物质进行贴合不作限定。
本申请一实施例中，该膜层结构2还可包括屏体，屏体用于发出显示光。将引导膜3贴合在膜层结构2的一侧之前，进一步包括将偏光片贴合在屏体的一侧。将引导膜3贴合在膜层结构2的一侧包括将引导膜3贴合在偏光片远离屏体的一侧。也就是说，当引导膜3为新增的膜层时，需要将膜层结构2中的各个膜层贴合完成后，再将引导膜3贴合在膜层结构2的一侧，能够防止当引导膜3对膜层结构2施加压力时，出现引导膜3和膜层结构2之间滑动导致贴合位置的偏移的问题，从而提高产品的良率。
偏光片和屏体之间可以使用光学胶进行贴合，还可以使用其他具有粘性的物质进行贴合，采用何种物质进行贴合可根据实际的产品进行选择，本申请对偏光片和屏体之间采用何种物质进行贴合不作限定。
图5所示为本申请一实施例提供的一种曲面显示面板的贴合方法的流程图。
如图5所示，膜层结构2进一步包括泡棉和触控层，泡棉可起到缓冲作用，泡棉设置在屏体的一侧；触控层设置在屏体的另一侧，触控屏可实现触摸功能；偏光片设置在所述触控层远离所述屏体的一侧。基于上述膜层结构2，将引导膜3贴合在所述偏光片远离所述屏体的一侧可包括：
步骤06：将屏体贴合在泡棉的一侧。
步骤07：将触控层贴合在屏体远离泡棉的一侧。
步骤08：将偏光片贴合在触控层远离屏体的一侧。
将泡棉、屏体、触控层和偏光片依次贴合形成膜层结构2，再将引导膜3贴合在膜层结构2的一侧，防止当引导膜3对膜层结构2施加压力时，出现引导膜3和膜层结构2之间滑动导致贴合位置偏移的问题，从而影响产品的良率。
上述贴合均可采用光学胶进行贴合，也可采用其他具有黏性的物质进行贴合，采用何种物质进行贴合可根据实际的产品需求进行调整，本申请对屏体和泡棉、屏体和触控层，触控层和偏光片之间采用何种物质进行贴合不作限定。
膜层结构2可包括屏体、泡棉和触控层，还可包括其它膜层，本申请对膜层结构2的具体包括的膜层不作限定。
图6所示为本申请一实施例提供的一种曲面显示面板的贴合方法的流程图。图7所示为本申请一实施例提供的一种排气孔5的结构示意图。图8所示为本申请一实施例提供的一种排气孔5的结构示意图。
如图6-图8所示，盖板4可以为普通的盖板4，也可以为包括排气孔的盖板4。如图6所示，盖板4可包括排气孔5。将贴合机构1沿靠近盖板4的方向移动，使引导膜3的部分与盖板4相贴合，通过贴合机构1对膜层结构2和引导膜3的挤压，将引导膜3全部贴合在盖板4上包括：
步骤09：在引导膜3远离膜层结构2的一侧设置光学胶层7，光学胶层7用粘贴引导膜3和盖板4。该光学胶层7的透过率可大于99％，折射率可为1.508，粘度为1200cps，该光学胶层7可以将盖板4和引导膜3粘贴牢固，且由于该光学胶层7具有良好的透过率，且折射率和盖板4相近，因此使用该光学胶层7不会 影响显示面板的显示效果。
不同材质的光学胶层7具有不同的黏度、不同的透过率和不同的折射率，可以根据实际的产品和需求对光学胶层7进行选择，本申请对光学胶层7的具体材质不做限定。
该光学胶层7可通过涂抹或使用类似双面胶的方式进行设置，本申请对光学胶层7的设置方式不作限定。
步骤10：将贴合机构1沿靠近盖板4的方向移动，使引导膜3的中心部分与盖板4相贴合。将引导膜3的中心部分即非预设弧度处与盖板4的非曲面部分相接触，能够保证引导膜3的边缘部分和盖板4的边缘部分不先接触，因此不会由于引导膜3的边缘部分和盖板4的边缘部分先接触后形成密闭的空间，导致贴合过程中气体的存在，从而减少了贴合过程中气泡的产生。
步骤11：将贴合机构1沿靠近盖板4的方向移动，使贴合机构1完全填充在盖板4靠近引导膜3的一侧内，通过贴合结构对膜层结构2和引导膜3施加压力，使引导膜3完全贴合在盖板4上，其中光学胶层7在压力的作用下产生形变填充进排气孔5内，将排气孔5内的空气排出。对盖板4沿靠近引导膜3的方向施加压力，使盖板4贴合在引导膜3上，且使光学胶层7填充进盖板4的排气孔5内，将排气孔5内的空气排出。盖板4上包括排气孔5，排气孔5可设置在盖板4的曲面形状处。对盖板4沿靠近引导膜3的方向施加压力，盖板4将压力传到与盖板4紧密接触的光学胶层7上，由于光学胶层7具有流动性，或光学胶层7在受到压力后产生形变，因此填充进排气孔5内，将排气孔5内的空气排出。由于盖板4的曲面形状处在贴合过程中容易产生气泡，将排气孔5的一端设置在气泡易产生处，排气孔5的另一端设置在盖板4的末端，在贴合过程中光学胶层7将盖板4和光学胶层7之间的空气排除，从而避免了气泡的产生，且由于光学胶层7填充进排气孔5内，光学胶层7的折射率和盖板4相同或相近，因此目视不会看出排气孔5的存在，不影响显示效果。且由于排气孔5在盖板4的弧形处，不会影响显示面板的使用手感等用户体验。
光学胶层7可以为液态光学胶层7，也可以为胶状光学胶层等，对光学胶层 7形态的选择可根据实际需求进行调整，本申请对光学胶的形态不作限定。
盖板4的排气孔5的直径可以为0.1mm～0.3mm，还可以为其它范围内的直径，排气孔5的直径大小可根据实际的产品进行调整，本申请对排气孔5的直径不做限定。
在盖板4的每侧的弧形处可设置3～5个排气孔5，或者每间隔10mm设置一个排气孔5，排气孔5的具体设置数量可根据实际的产品进行调整，本申请对排气孔5的数量不做限定。
排气孔5的一端设置在盖板4弧形处的末端，排气孔5另一端的设置位置可通过有限元仿真确定，本申请对排气孔5的具体位置和具体位置的确定方法不作限定。
排气孔5可以为孔状结构(如图7所示)，其中孔状结构的排气孔5可采用分体式模具制造而成；排气孔5也可以为槽状结构(如图8所示)，使用流动性较差的光学胶进行贴合时，槽状结构的排气孔5更易将气体全部排出，且槽状结构的排气孔5制造难度低，易于实现，排气孔5的具体结构可根据实际的需求进行选择，本申请对排气孔5的具体结构和制备方法不做限定。
本申请一实施例中，在引导膜3远离膜层结构2的一侧设置光学胶层7包括：引导膜3的边缘位置对应的光学胶层7的厚度大于在引导膜3的其余部位对应的光学胶层7的厚度。由于膜层结构2具有预设弧度处位于膜层结构2的边缘，预设弧度处对应盖板4的弧形处，因此在膜层结构2的预设弧度处也就是边缘处设置光学胶层7，在盖板4的贴合过程中会填充进排气孔5内，因此在膜层结构2的边缘设置光学胶层7的厚度大于在膜层结构2其余部位设置光学胶层7的厚度，在粘贴完盖板4和引导膜3后，能够保证有足够多的光学胶层7用于填充进排气孔5内，防止光学胶层7无法填充进排气孔5而造成气泡的产生，影响产品良率。
在膜层结构2的边缘涂抹的光学胶层7的厚度可以为0.15mm～0.2mm，在膜层结构2其余部位涂抹光学胶层7的厚度可以为0.1mm。具体的光学胶层7的厚度可根据实际的产品进行调整，本申请对光学胶层7的厚度不做限定。
图9所示为本申请一实施例提供的一种预应力开孔8和易撕线9的结构示意 图。
如图9所示，引导膜3包括易撕线9和预应力开孔8。正如上述实施例中所述，由于需要对引导膜3进行拉拽，所以引导膜3的表面积要大于膜层结构2的表面积，多出的表面积可位于引导膜3的四周边缘处，引导膜3的四周边缘部分用于人手或机械设备对引导膜3进行固定并施力。易撕线9可设置在引导膜3需要撕除的部分和无需撕除的部分的交界线处，预应力开孔8可设置在易撕线9的至少一端处。步骤04除掉引导膜3四周边缘部分可包括从预应力开孔8处施力，沿易撕线9将引导膜3的四周边缘部分撕除。在引导膜3上设置易撕线9和预应力开孔8，贴合时，夹爪6抓住引导膜3边缘向模组结构的方向拉拽时，易撕线9不会断裂；贴合完毕后，由机械手或手动从预应力开孔8处加力，可撕除引导膜3的四周边缘部分，从而无需增加额外的工具，简化了撕除步骤方便易操作。
可以采用设置预应力开口和易撕线9的方式撕除引导膜3的四周边缘部分，也可以采用其它的方式对引导膜3的四周边缘部分进行撕除操作，具体采用何种方式对引导膜3的四周边缘部分进行撕除操作可根据实际的产品进行选择，本申请对引导膜3的四周边缘部分进行撕除的方法不作限定。
以上仅为本申请的较佳实施例而已，并非用于限定本申请的保护范围。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
