具体实施方式
现在将参考附图更全面地描述示例实施方式。然而，示例实施方式能够以多种形式实施，且不应被理解为限于在此阐述的实施方式；相反，提供这些实施方式使得本公开将全面和完整，并将示例实施方式的构思全面地传达给本领域的技术人员。图中相同的附图标记表示相同或类似的结构，因而将省略它们的详细描述。此外，附图仅为本公开的示意性图解，并非一定是按比例绘制。

参照图1和图2所示，将盖板2与显示面板1贴合前，通常会将显示面板1的非显示面贴合在支撑板3上，然后将支撑板3贴合在承载膜8上，承载膜8的长度大于显示面板1的长度，在承载膜8的两端部施加拉力，然后将承载膜8的部分围绕在滑块11上，使承载膜8、支撑板3和显示面板1形成与滑块11外轮廓相似的形状，例如，在滑块11的圆弧区，承载膜8、支撑板3和显示面板1均形成圆弧形，这一过程称为仿形；在这一过程中，由于在滑块11的圆弧区显示面板1和支撑板3具有一定的反弹力作用，显示面板1和支撑板3会有一定的翘曲、隆起，使得显示面板1与滑块11之间存在较大的间隙，使得仿形后的显示面板1的相对两平面部之间的距离增大，而盖板2的容纳显示面板1的空间的高度不会变化，从而导致滑块11不能顺利地带动承载膜8、支撑板3以及显示面板1进入盖板2的容纳空间内；而且，在贴合过程中滑块11带动显示面板1移动不容易使盖板2与显示面板1贴合，在盖板2与显示面板1贴合过程中容易产生气泡，也会产生褶皱。
本公开示例实施方式提供了一种显示装置，参照图2所示，该显示装置可以包括盖板2、显示面板1以及支撑板3；盖板2至少包括第一平面部21、第二平面部22和第一曲面部23，第一曲面部23平滑连接于第一平面部21和第二平面部22之间，第二平面部22与第一平面部21平行，所述第一曲面部沿第一方向延伸，第一曲面部23在第一基准面上的正投影为弧形，第一基准面与第一方向垂直，第一平面部21、第二平面部22和第一曲面部23围设成容纳空间；显示面板1设于容纳空间；支撑板3至少包括依次连接的第一平直支撑部3a、第一弧面支撑部3b和第二平直支撑部3c，第一弧面支撑部3b的模量小于第一平直支撑部3a的模量，且第一弧面 支撑部3b的模量小于第二平直支撑部3c的模量；第一平直支撑部3a贴合于显示面板1的远离第一平面部21的一侧，第一弧面支撑部3b贴合于显示面板1的远离第一曲面部23的一侧，第二平直支撑部3c贴合于显示面板1的远离第二平面部22的一侧。
本公开的显示装置，第一弧面支撑部3b的模量小于第一平直支撑部3a的模量，且小于第二平直支撑部3c的模量；第一平直支撑部3a贴合于显示面板1的远离第一平面部21的一侧，第二平直支撑部3c贴合于显示面板1的远离第二平面部22的一侧，使得支撑板3具有足够的强度以达到对显示面板1支撑的作用；第一弧面支撑部3b贴合于显示面板1的远离第一曲面部23的一侧，使得支撑板3具有足够的柔性，在折弯时支撑板3不容易翘曲、隆起，从而避免显示面板1翘曲、隆起，使得仿形后的显示面板1的相对两平面部之间的距离不会增大，使滑块11、承载膜8、支撑板3以及显示面板1能够顺利地进入盖板2内；而且，显示面板1与滑块11贴合较为紧密，在贴合过程中滑块11带动显示面板1移动容易使盖板2与显示面板1贴合，在盖板2与显示面板1贴合过程中不容易产生气泡，也不会产生褶皱。
盖板2可以是环绕形盖板2。
在本示例实施方式中，参照图3所示，盖板2可以包括第一平面部21、第一曲面部23以及第二平面部22。第一平面部21、第一曲面部23以及第二平面部22依次连接形成“U”字形。
具体来说，第一平面部21可以设置为长方形；第一平面部21可以包括相对设置的第一平面和第二平面。第一曲面部23平滑连接于第一平面部21的一侧，例如，第一曲面部23可以平滑连接于第一平面部21的一侧长边，使得第一曲面部23沿第一平面部21的长边延伸。当然，在本公开的其他示例实施方式中，第一曲面部23可以平滑连接于第一平面部21的一侧短边，使得第一曲面部23沿第一平面部21的短边延伸；第一平面部21还可以设置为其他形状，第一曲面部23的延伸方向与第一平面部21的边沿的延伸方向一致，该边沿是第一平面部21的与第一曲面部23连接的边沿。第一曲面部沿第一方向延伸，第一方向是第一曲面部所形成的弧面对应的轴线的延伸方向。
第一曲面部23在第一基准面上的正投影为弧形，例如，可以是半圆弧形、半椭圆弧形、抛物线弧形等等；第一基准面与第一曲面部的延伸方向垂直，即第一基准面与第一方向垂直。即第一基准面与上述边沿垂直，上述边沿为第一平面部21的与第一曲面部23连接的边沿。具体地，第一曲面部23可以包括相对设置的第一曲面和第二曲面，第一曲面在第一基准面上的正投影为半圆弧线，第二曲面的在第一基准面上的正投影也为半圆弧线；两个半圆弧线相互平行，两个半圆弧线连接形成半圆弧形。
第一曲面与第一平面连接，且第一曲面与第一平面相切；第二曲面与第二平面 连接，且第二曲面与第二平面相切，即使得第一曲面部23与第一平面部21平滑连接。
第二平面部22也可以设置为长方形，第二平面部22平滑连接于第一曲面部23的相对另一侧，第二平面部22与第一平面部21平行。第二平面部22可以包括相对设置的第三平面和第四平面，第三平面可以与第一曲面连接，且第一曲面与第三平面相切；第四平面与第二曲面连接，且第二曲面与第四平面相切，即使得第一曲面部23与第二平面部22平滑连接。
在本示例实施方式中，第二平面部22的宽度与第一平面部21的宽度可以相同。第一曲面部23的长度、第二平面部22的长度与第一平面部21的长度可以相同。当然，在本公开的其他示例实施方式中，第二平面部22的宽度与第一平面部21的宽度也可以不相同，第一曲面部23的长度、第二平面部22的长度与第一平面部21的长度也可以不相同。
需要说明的是，参照图7所示，长度方向Y均是与第一曲面部23延伸方向一致的方向，宽度方向X是与第一曲面部23延伸方向垂直的方向；当然，厚度方向Z也与第一曲面部23延伸方向垂直，但是厚度方向Z与第一平面部21和第二平面部22之间的间隔距离的方向一致。长度方向Y就是第一方向，宽度方向X就是第二方向。
请继续参照图2所示，在盖板2的容纳空间设置有显示面板1，显示面板1与第一平面部21相对的部分为第一平面区，显示面板1与第一曲面部23相对的部分为曲面区，显示面板1与第二平面部22相对的部分为第二平面区；且由于第一平面部21与第二平面部22是平行的，显示面板1的第一平面区与第二平面区也是相互平行的。而且，由于第二平面部22的宽度与第一平面部21的宽度是相同的，显示面板1的第一平面区的宽度与第二平面区的宽度也是相同的。
显示面板1的显示面与盖板2的内侧面贴合，具体地，显示面板1的显示面与盖板2的内侧面通过第一胶层4贴合，第一胶层4可以是OCA(Optically Clear Adhesive)光学胶。
需要说明的是，盖板2的容纳空间指的是第一曲面部23的圆心所在的一侧，第一曲面部23与第一平面部21和第二平面部22连接后形成一个半包围形的结构，半包围结构的容纳空间即为盖板2的容纳空间。
在显示面板1的远离盖板2的一侧设置有支撑板3，即在显示面板1的与显示面相对的一侧设置有支撑板3。支撑板3对显示面板1起到支撑作用。
具体来说，参照图4和图5所示，支撑板3可以包括第一层31、第二层32以及第三层33。第一层31设于显示面板1的远离盖板的一侧，第二层32设于第一层31的远离盖板的一侧，第二层32也设于第一层31的远离盖板的一侧。
具体地，第一层31可以包括依次连接的第一部分311、第二部分312和第三部 分313，第二部分312形成第一弧面支撑部3b；第二部分312贴合于显示面板1的远离第一曲面部的一侧。第二部分312的厚度大于第一部分311的厚度，且第二部分312的厚度大于第三部分313的厚度。当然，第一部分311、第二部分312和第三部分313三者的厚度可以相同。
第二层32设于第一部分311的远离显示面板1的一侧，且第二层32与第一部分311形成第二平直支撑部3c，即第二平直支撑部3c可以包括第二层32和第一部分311；第一层31的模量小于第二层32的模量，从而使得第二平直支撑部3c的模量大于第一弧面支撑部3b的模量。
第三层33设于第三部分313的远离显示面板1的一侧，且第三层33与第三部分313形成第一平直支撑部3a，即第一平直支撑部3a可以包括第三层33和第三部分313；第一层31的模量小于第三层33的模量，从而使得第一平直支撑部3的模量大于第一弧面支撑部3b的模量。使得支撑板3具有足够的强度以达到对显示面板1支撑的作用，而与第一曲面部23相对的支撑板3仅包括模量较小的第一层31的第二部分312，使得支撑板3具有足够的柔性，在折弯时不容易翘曲、隆起，从而避免显示面板1翘曲、隆起。
第二部分312的厚度等于第一部分311的厚度与第二层32的厚度之和，且第二部分312的厚度等于第三部分313的厚度与第三层33的厚度之和，使得支撑板3的整体厚度一致，避免支撑板3出现凸凹不平的现象。
第二层32和第三层33的厚度均大于等于15微米且小于等于200微米，第一部分311的厚度和第三部分313大于等于10微米且小于等于200微米，那么，第二部分312的厚度大于等于25微米且小于等于400微米。
第一层31的材质可以是泡棉，第二层32、第三层33和第四层34的材质可以是sus304不锈钢板。
当然，在本公开的其他示例实施方式中，第二部分312的厚度也可以大于或小于第一部分311的厚度与第二层32的厚度之和，第二部分312的厚度也可以大于或小于第三部分313的厚度与第三层33的厚度之和；而且，第一层31的材质还可以是橡胶、柔性树脂等等柔性材质，第二层32和第三层33的材质还可以是其他成分的不锈钢板、硬质塑料板等等。
第二层32和第三层33设置在第一层31的远离显示面板1的一侧，即第一层31直接与显示面板1接触，第一层31具有一定的弹性，避免在折弯过程中第二层32和第三层33对显示面板1的损伤；而且，显示面板1工作时需要通电，第一层31一般为绝缘材料，第二层32和第三层33一般为导电材料，第一层31能进一步起到绝缘作用。
支撑板3的长度大于或等于显示面板1的长度，支撑板3的宽度大于或等于显示面板1的宽度。
第二层32的长度和第三层33的长度可以与支撑板3的长度相同，第二层32的宽度可以与第一平面部21的宽度相同，第三层33的宽度可以与第二平面部22的宽度相同。另外，在本公开的另一些示例实施方式中，可以设置有多个第二层32，第二层32设置为条状，多个第二层32相互平行设于第一部分311的远离显示面板1的一侧，这种情况下，各个第二层32的宽度较小，相邻两个第二层32之间可以间隔设置，也可以不间隔设置；当然，同理，也可以设置有多个第三层33，第三层33设置为条状，多个第三层33相互平行设于第三部分313的远离显示面板1的一侧，这种情况下，各个第三层33的宽度较小，相邻两个第三层33之间可以间隔设置，也可以不间隔设置。
在本示例实施方式中，请继续参照图2所示，在显示面板1与支撑板3之间还设置有保护层5；保护层5与显示面板1通过第二胶层6粘接，第二胶层6可以是压敏胶。保护层5与支撑板3通过第三胶层7粘接，第三胶层7也可以是OCA光学胶。第三胶层7可在显示面板1与支撑板3之间起缓冲作用，可降低显示面板1在环绕型贴合过程中产生裂纹(crack)的风险。
另外，盖板2的结构不限于上述说明，在本公开的另一示例实施方式中，参照图6和图7所示，盖板2还可以包括第二曲面部24，第二曲面部24平滑连接于第一平面部21远离第一曲面部23的一侧，第二曲面部24与第一曲面部23向第一平面部21的同一侧弯曲，第二曲面部24在第一基准面上的正投影为弧形，例如，可以是四分之一圆弧或椭圆弧、三分之一圆弧或椭圆弧等等。
具体地，第二曲面部24可以包括相对设置的第三曲面和第四曲面，第三曲面与第一平面连接，且第三曲面与第一平面相切；第四曲面与第二平面连接，且第四曲面与第二平面相切，即使得第二曲面部24与第一平面部21平滑连接。
而且，第二曲面部24的圆心与第一曲面部23的圆心位于第一平面部21的同一侧，即第二曲面部24与第一曲面部23向第一平面部21的同一侧弯曲。
第二曲面部24在第一基准面上的正投影为四分之一圆弧。具体地，第三曲面在第一基准面上的正投影为四分之一圆弧线，第四曲面在第一基准面上的正投影也为四分之一圆弧线；两个四分之一圆弧线相互平行，两个四分之一圆弧线连接形成四分之一圆弧形。
且，在该示例实施方式中，第二平面部22的宽度小于第一平面部21的宽度，使得盖板2具有足够大的间隙，能够使贴合系统的机械臂能够在该间隙内滑动，完成盖板2与显示面板的贴合工艺。
这种情况下，显示面板1与盖板2贴合后形成两个平面区和两个曲面区；其中一个平面区与盖板2的第一平面部21相贴合，且该平面区的长度和宽度与第一平面部21的长度和宽度基本相同；另一个平面区与盖板2的第二平面部22相贴合，且该平面区的长度和宽度与第二平面部22的长度和宽度基本相同；其中一个曲面区与 盖板2的第一曲面部23相贴合，且该曲面区的长度和宽度与第一曲面部23的长度和宽度基本相同，该曲面区折弯形成半圆弧形；另一个曲面区与盖板2的第二曲面部24相贴合，且该曲面区的长度和宽度与第二曲面部24的长度和宽度基本相同，该曲面区折弯形成四分之一圆弧形。
同样，为了与上述盖板2对应，参照图8所示，支撑板还可以包括第二弧面支撑部3d，第二弧面支撑部3d连接于第一平直支撑部3a远离第一弧面支撑部3b的一侧，且第二弧面支撑部3d贴合于显示面板的远离第二曲面部的一侧，第二弧面支撑部3d的模量小于第一平直支撑部3a的模量，第二弧面支撑部3d的模量小于第二平直支撑部3c的模量。

第一部分311的宽度小于第三部分313的宽度，第二层32的宽度小于第三层33的宽度。
在本公开的再一示例实施方式中，参照图9所示，第一曲面部23可以设置为两个，两个第一曲面部23对称平滑连接于第一平面部21的相对两侧；第一曲面部23与第一平面部21的连接结构上述已经进行了详细说明，因此，此处不再赘述。第二平面部22设置为两个，两个第二平面部22对称平滑连接于两个第一曲面部23的另一侧，即一个第二平面部22连接一个第一曲面部23；两个第二平面部22之间设置有间隙，即两个第二平面部22的宽度之和小于第一平面部21的宽度，使得贴合系统的机械臂能够在该间隙内滑动，完成盖板2与显示面板的贴合工艺。上述示例实施方式中两个第二平面部22的宽度是相同的，需要说明的是，两个第二平面部22 的宽度也可以不同。
这种情况下，显示面板1与盖板2贴合后形成三个平面区和两个曲面区，其中一个平面区与盖板2的第一平面部21相贴合，且该平面区的长度和宽度与第一平面部21的长度和宽度基本相同；另两个平面区与盖板2的第二平面部22相贴合，且这两个平面区的长度和宽度与第二平面部22的长度和宽度基本相同；两个曲面区一一对应的与盖板2的两个第一曲面部23相贴合，且这两个曲面区的长度和宽度与第一曲面部23的长度和宽度基本相同，该这两个曲面区折弯形成半圆弧形。

另外，在本公开的另一些示例实施方式中，可以设置有多个第四层34，第四层34设置为条状，多个第四层34相互平行设于第六部分316的远离显示面板1的一侧，这种情况下，各个第四层34的宽度较小，相邻两个第四层34之间可以间隔设置，也可以不间隔设置。
需要说明的是，上述第一层31、第二层32、第三层33以及第四层34只用于指代不同的结构部分，并不用于限定膜层的堆叠顺序。
进一步，本公开示例实施方式还提供了一种贴合系统，用于贴合上述任意一项所述的显示装置，该贴合系统可以包括工作台、承载膜8、夹持部9、机械臂10以及滑块11等等，工作台可以用于固定盖板2；承载膜8可以用于依次贴合有支撑板3和显示面板1；夹持部9可以用于夹持承载膜8的相对两端；滑块11连接于机械臂10的一端，承载膜8围绕在滑块11外，机械臂10用于带动滑块11运动使显示面板1与盖板2贴合。
在本示例实施方式中，机械臂10的一端可以固定在工作台上。机械臂10的另一端连接滑块11，机械臂10能够带动滑块11运动。贴合系统还可以包括夹持臂(图中未示出)，夹持臂的一端固定在工作台上，夹持臂的另一端连接夹持部9；夹持臂设置为两个，对应的夹持部9也设置为两个，夹持臂与夹持部9是一一对应的关系。两个夹持部9一一对应地夹持承载膜8的相对两端。夹持臂能够带动夹持部9运动。
需要说明的是，承载膜8的相对两端指的是承载膜8处于展开状态时，在第二方向上的相对两端。
在本示例实施方式中，承载膜8的材质可以是高分子聚乙烯丙纶(PPF)。
为了与上述三种示例实施方式的盖板2对应，滑块11也可以设置为三种结构，下面对滑块11的结构进行详细说明。
滑块11可以设置为长方体状。具体地，对应于图3所示的盖板2，参照图5所示，滑块11可以包括第一平坦面、第二平坦面以及第一圆弧面；第二平坦面与第一平坦面相对且平行设置，第二平坦面的长度和宽度与第一平坦面的长度和宽度可以相同；第一圆弧面平滑连接于第一平坦面和第二平坦面之间，即第一圆弧面的一端平滑连接于第一平坦面的一端，第一圆弧面的另一端平滑连接于第二平坦面的一端；第一圆弧面可以为半圆弧面，也可以是半椭圆弧面、半抛物线弧面等等。
贴合系统还可以包括凸块111，凸块111设于第二平坦面，且凸块111与第二平坦面之间有第一间隙112，承载膜8的一端能够穿过第一间隙112。
盖板2固定在工作台上，且盖板2的第一平面部21相对于第二平面部22更靠近工作台。夹持部9夹持承载膜8后向第二平面部22一侧拉紧，与滑块11的第二平坦面围绕的承载膜8在夹持部9的拉力作用下会被拉起，导致承载膜8与第二平坦面不围绕，设置凸块111和第一间隙112，承载膜8穿过第一间隙112，可以避免 承载膜8被拉起而与第二平坦面不围绕。
在对显示面板1与盖板2进行贴合时，第一平坦面与第一平面部21相对，滑块11的第一平坦面对显示面板1进行施压，使显示面板1与第一平面部21贴合；第二平坦面与第二平面部22相对，滑块11的第二平坦面对显示面板1进行施压，使显示面板1与第二平面部22贴合；第一圆弧面与第一曲面部23相对，滑块11的第一圆弧面对显示面板1进行施压，使显示面板1与第一曲面部23贴合。
对应于图6所示的盖板2，参照图11所示，滑块11可以包括第一平坦面、第二平坦面、第一圆弧面以及第二圆弧面；第二平坦面与第一平坦面相对且平行设置，第二平坦面的长度与第一平坦面的长度可以相同，但是，第二平坦面的宽度与第一平坦面的宽度不同；第一圆弧面平滑连接于第一平坦面和第二平坦面之间，即第一圆弧面的一端平滑连接于第一平坦面的一端，第一圆弧面的另一端平滑连接于第二平坦面的一端；第一圆弧面为半圆弧面。第二圆弧面平滑连接于第一平坦面的远离第一圆弧面的一侧，第二圆弧面可以为四分之一圆弧面，也可以是四分之一椭圆弧面、四分之一抛物线弧面、三分之一圆弧面等等。
贴合系统还可以包括凸块111，凸块111设于第二平坦面，且凸块111与第二平坦面之间有第一间隙112，承载膜8的一端能够穿过第一间隙112。
盖板2固定在工作台上，且盖板2的第一平面部21相对于第二平面部22更靠近工作台。夹持部9夹持承载膜8后向第二平面部22一侧拉紧，与滑块11的第二平坦面围绕的承载膜8在夹持部9的拉力作用下会被拉起，而与第二平坦面不围绕，设置凸块111和第一间隙112，承载膜8穿过第一间隙112，可以避免承载膜8被拉起而与第二平坦面不围绕。
在对显示面板1与盖板2进行贴合时，第一平坦面与第一平面部21相对，滑块11的第一平坦面对显示面板1进行施压，使显示面板1与第一平面部21贴合；第二平坦面与第二平面部22相对，滑块11的第二平坦面对显示面板1进行施压，使显示面板1与第二平面部22贴合；第一圆弧面与第一曲面部23相对，滑块11的第一圆弧面对显示面板1进行施压，使显示面板1与第一曲面部23贴合；第二圆弧面与第二曲面部24相对，滑块11的第二圆弧面对显示面板1进行施压，使显示面板1与第二曲面部24贴合。
对应于图9所示的盖板2，参照图12所示，滑块11可以包括第一平坦面、两个第二平坦面以及两个第一圆弧面；两个第一圆弧面对称平滑连接于第一平坦面和第二平坦面之间，第一圆弧面的一端平滑连接于第一平坦面的一端，第一圆弧面的另一端平滑连接于第二平坦面的一端；两个第二平坦面对称平滑连接于两个第一圆弧面。第二平坦面与第一平坦面相对且平行设置，第二平坦面的长度与第一平坦面的长度可以相同，但是，第二平坦面的宽度与第一平坦面的宽度不同；第一圆弧面平滑连接于第一平坦面和第二平坦面之间，即第一圆弧面的一端平滑连接于第一平 坦面的一端，第一圆弧面的另一端平滑连接于第二平坦面的一端；第一圆弧面为半圆弧面。
贴合系统还可以包括凸块111，凸块111设于第二平坦面，且凸块111与第二平坦面之间有两个第一间隙112，在凸块111上还设置有两个第二间隙113，第二间隙113的延伸方向与第一间隙112的延伸方向相交，例如，可以是垂直；两个第二间隙113与两个第一间隙112对应连通，承载膜8的一端能够穿过一个第一间隙112和一个第二间隙113，承载膜8的另一端能够穿过另一个第一间隙112和另一个第二间隙113。另外，在本公开的其他示例实施方式中，可以将上述两个第一间隙112连通形成一个第一间隙112，承载膜8的两端分别从第一间隙112的两侧穿入，第二间隙113也可以设置为一个，只是宽度较宽可以同时容纳两层承载膜8，而且保证两层承载膜8运动时互不干扰。
盖板2固定在工作台上，且盖板2的第一平面部21相对于第二平面部22更靠近工作台。夹持部9夹持承载膜8后向第二平面部22一侧拉紧，与滑块11的第二平坦面围绕的承载膜8在夹持部9的拉力作用下会被拉起，而与第二平坦面不围绕，设置凸块111、第一间隙112和第二间隙113，承载膜8穿过第一间隙112和第二间隙113，可以避免承载膜8被拉起而与第二平坦面不围绕。
在对显示面板1与盖板2进行贴合时，第一平坦面与第一平面部21相对，滑块11的第一平坦面对显示面板1进行施压，使显示面板1与第一平面部21贴合；第二平坦面与第二平面部22相对，滑块11的第二平坦面对显示面板1进行施压，使显示面板1与第二平面部22贴合；第一圆弧面与第一曲面部23相对，滑块11的第一圆弧面对显示面板1进行施压，使显示面板1与第一曲面部23贴合。
进一步，本公开示例实施方式还提供了一种贴合方法，用上述任意一项所述的贴合系统贴合形成上述任意一项所述的显示装置，参照图13所示，该贴合方法可以包括以下步骤：
步骤S10，在承载膜8的一面依次粘接支撑板3和显示面板1，在所述显示面板1的远离所述承载膜8的一侧形成第一胶层4。
步骤S20，将所述承载膜8围绕于滑块11外，通过夹持部9夹持所述承载膜8的相对两端对所述显示面板1进行仿形。
步骤S30，机械臂10带动所述滑块11沿第一方向移动至盖板2的容纳空间。
步骤S40，机械臂10带动所述滑块11沿第二方向移动使显示面板1与第一曲面部接触，机械臂10带动所述滑块11沿所述第一曲面部滑动完成显示面板1与第一曲面部的贴合。
步骤S50，机械臂10带动所述滑块11沿与第一平面部垂直的方向移动完成显示面板1与第一平面部的贴合。
下面对贴合方法进行详细说明。
需要说明的是，承载膜8围绕于滑块11外，承载膜8大约围绕滑块11的三个面，而没有将滑块11完全围绕。
在承载膜8的一面贴合支撑板3，在支撑板3的远离承载膜8的一面涂覆第三胶层7，在第三胶层7的远离承载膜8的一面贴合保护层5，在保护层5的远离承载膜8的一面涂覆第二胶层6，在第二胶层6的远离承载膜8的一面贴合显示面板1，在显示面板1的远离承载膜8的一面涂覆第一胶层4。
支撑板3与保护层5之间的粘附力为12N/25mm 2，即第三胶层7的粘附力为12N/25mm 2。支撑板3与承载膜8之间的粘附力为2000gf/inch，UV减黏后粘附力＜10gf/inch。支撑板3与承载膜8之间的粘附力小于支撑板3与保护层5之间的粘附力，使得完成显示面板1的贴合后，将承载膜8剥离支撑板3时，不会将支撑板3剥离保护层5。
参照图5、图11、图12所示，将承载膜8围绕于滑块11外，并将承载膜8穿过第一间隙112或第一间隙112和第二间隙113；通过夹持部9夹持承载膜8的相对两端并将承载膜8张紧对显示面板1进行仿形。
机械臂10带动滑块11沿第一方向移动，使滑块11以及其上围绕的各个膜层移动至盖板2的容纳空间。
对于图3所示的盖板2，参照图14所示，图中箭头方向为移动方向，此时两个夹持部9均处于张紧位，使承载膜8处于张紧状态；机械臂10带动滑块11向靠近第一曲面部23一侧移动，直至显示面板1与第一曲面部23贴合形成如图15所示的结构，图中箭头方向为移动方向，此时位于下方的夹持部9均处于张紧位，位于上方的夹持部9均处于松弛位，使承载膜8的下半部分处于张紧状态，上半部分处于松弛状态，避免后续进行的下半部分的贴合时出现气泡、褶皱等等不良，机械臂10带动滑块11沿第一曲面部23向下运动大约四分之一圆弧，使显示面板1与第一曲面部23的下半部分贴合，然后机械臂10带动滑块11继续向下运动，即机械臂10带动滑块11向靠近第一平面部21的一侧移动，直至显示面板1与第一平面部21贴合；然后，使位于下方的夹持部9均处于松弛位，位于上方的夹持部9均处于张紧位，使承载膜8的下半部分处于松弛状态，上半部分处于张紧状态，避免后续进行的上半部分的贴合时出现气泡、褶皱等等不良，机械臂10带动滑块11沿第一曲面部23向上运动大约二分之一圆弧，使显示面板1与第一曲面部23完全贴合，然后机械臂10带动滑块11继续向上运动，即机械臂10带动滑块11向靠近第二平面部22的一侧移动，直至显示面板1与第二平面部22贴合形成如图16所示的结构；最后，机械臂10带动滑块11退出盖板2的容纳空间。当然，也可以沿第一曲面部23先向上移动，完成显示面板1与第一曲面部23的上半部分的贴合，以及显示面板1与第二平面部22的贴合；然后，再沿第一曲面部23向下移动，完成显示面板1与第一曲面部23的完全贴合，以及显示面板1与第一平面部21的贴合。
对于图6所示的盖板2，参照图17所示，图中箭头方向为移动方向，此时两个夹持部9均处于张紧位，使承载膜8整体处于张紧状态；机械臂10带动滑块11向靠近第一曲面部23一侧移动，直至显示面板1与第一曲面部23贴合形成如图18所示的结构，图中箭头方向为移动方向，此时位于下方的夹持部9均处于张紧位，位于上方的夹持部9均处于松弛位，使承载膜8的下半部分处于张紧状态，上半部分处于松弛状态，避免后续进行的下半部分的贴合时出现气泡、褶皱等等不良，机械臂10带动滑块11沿第一曲面部23向下运动大约四分之一圆弧，使显示面板1与第一曲面部23的下半部分贴合；然后，使位于下方的夹持部9均处于松弛位，位于上方的夹持部9均处于张紧位，使承载膜8的下半部分处于松弛状态，上半部分处于张紧状态，避免后续进行的上半部分的贴合时出现气泡、褶皱等等不良，机械臂10带动滑块11沿第一曲面部23向上运动大约二分之一圆弧，使显示面板1与第一曲面部23完全贴合，然后机械臂10带动滑块11继续向上运动，即机械臂10带动滑块11向靠近第二平面部22的一侧移动，直至显示面板1与第二平面部22贴合形成如图19所示的结构，图中箭头方向为移动方向，此时位于下方的夹持部9均处于张紧位，位于上方的夹持部9均处于松弛位，使承载膜8的下半部分处于张紧状态，上半部分处于松弛状态，避免后续进行的下半部分的贴合时出现气泡、褶皱等等不良；机械臂10带动滑块11向靠近第一平面部21的一侧移动，直至显示面板1与第一平面部21贴合形成如图20所示的结构，图中箭头方向为移动方向，机械臂10带动滑块11向靠近第二曲面部24的一侧移动形成如图21所示的结构，图中箭头方向为移动方向，然后，机械臂10带动滑块11沿第二曲面部24向上运动大约四分之一圆弧，直至显示面板1与第二曲面部24完全贴合形成如图22所示的结构。最后，机械臂10带动滑块11退出盖板2的容纳空间。
对于图9所示的盖板2，参照图23所示，图中箭头方向为移动方向，此时两个夹持部9均处于张紧位，使承载膜8整体处于张紧状态；机械臂10带动滑块11向上移动，直至显示面板1与左侧第一曲面部23的上边沿贴合形成如图24所示的结构，图中箭头方向为移动方向，此时位于右侧的夹持部9均处于张紧位，位于左侧的夹持部9均处于松弛位，使承载膜8的右半部分处于张紧状态，左侧部分处于松弛状态，机械臂10带动滑块11沿左侧第一曲面部23向下运动大约二分之一圆弧，使显示面板1与左侧第一曲面部23完全贴合，然后机械臂10带动滑块11继续向下运动，即机械臂10带动滑块11向靠近第一平面部21的一侧移动，直至显示面板1与第一平面部21贴合形成如图25所示的结构，图中箭头方向为移动方向；机械臂10带动滑块11沿右侧第一曲面部23向上运动大约二分之一圆弧，使显示面板1与右侧第一曲面部23完全贴合，然后两个夹持部9均处于张紧位，使承载膜8整体处于张紧状态，机械臂10带动滑块11继续向上运动，即机械臂10带动滑块11向靠近第二平面部22的一侧移动，直至显示面板1与第二平面部22贴合形成如图26所 示的结构。最后，机械臂10带动滑块11退出盖板2的容纳空间。
