如图3所示，背板21用于支撑设置在其上的显示面板22。具体的，第一背板211用于承载第一非弯曲区221，第二背板212用于承载第二非弯曲区222。
显示面板22的弯曲区223朝背板21方向弯曲，形成弯曲空间24。其中，该弯曲空间24为半圆柱形状。在一实施例中，弯曲区223朝背板21方向弯曲后，可以在第一背板211和第二背板212之间设置一胶体层25，以将第一背板211和第二背板212贴合在一起。
支撑结构23填充在弯曲空间24内。支撑结构24用于支撑显示面板22的弯曲区221。支撑结构23可以采用具有弹性的材料制成。在一实施例中，支撑结构23的组成材料包括热固胶、橡胶或硅胶。
如图2所示，支撑结构23为与弯曲空间24匹配的半圆柱形状。该支撑结构23的截面半径为R，则该截面半径R不小于弯曲空间24的截面半径，即不小于弯曲空间的弯曲半径。这样，支撑结构23可以完全撑起弯曲区223，并且在弯曲区223受到外界应力的时候，可以有效帮助弯曲区223缓解应力。
如图3所示，支撑结构23包括本体231和第一圆柱体232。该本体231的形状为与该弯曲空间24匹配的半圆柱形。第一圆柱体232设置在该本体2的一端。其中，本体231的截面半径r不小于所述弯曲空间24的截面半径。本体231可以完全撑起弯曲区223，并且在弯曲区223受到外界应力的时候，可以有效帮助弯曲区223缓解应力。第一圆柱体232的直径d1小于所述弯曲空间24的截面半径，便于支撑结构23插入该弯曲空间24中。支撑结构23完全插入弯曲空间24后，可以在第一圆柱体232侧滴入胶水，固定该支撑结构23。
在一实施例中，支撑结构23还包括第二圆柱体233。该第二圆柱体233设置在本体231远离第一圆柱体231的一侧。其中，第二圆柱体233的直径d2也小于弯曲空间24的截面半径。这样，在将支撑结构23插入弯曲空间24时，不需要对支撑结构23的两端进行区分，便于支撑结构23快速插入弯曲空间24中。支撑结构23完全插入弯曲空间24后，可以在第一圆柱体232和第二圆柱体233两侧均滴入胶水，固定该支撑结构23。
综上，如图2或3所示，可以设置支撑结构23的高度H等于弯曲空间24的高度。
在一实施例中，如图4所示，可以在该显示面板22的弯曲区22弯曲之前，预先将该支撑结构23设置在弯曲区221靠近背板21的一侧。然后弯曲该弯曲区22，形成弯曲空间24，支撑结构23随之填充该弯曲空间24。
优选的，可以常温状态下，在该弯曲区221靠近背板21的一侧涂布热固材料。此时热固材料处于凝胶状态，不会影响后续弯折弯曲区22。然后弯曲该弯曲区22，形成弯曲空间24。由于常温下，热固材料具有流动性，因此该热固材料将分散在整个弯曲空间24内。接着再在80度至100度的温度下，加热该热固材料，使该热固材料凝固，即形成该支撑结构23。其中，该热固材料可以为热固胶。
其中，如图5所示，当支撑结构23的组成材料为热固胶等热固材料时，受加工工艺以及热固材料自身特性的影响，经热固化处理后的热固材料，可能形成表面为不规则曲面形状的支撑结构23。且该支撑结构23部分填充该弯曲空间24，使该弯曲空间24也为与该支撑结构23匹配的不规则曲面形状。
在一实施例中，如图6所示，也可以在该显示面板22的弯曲区22弯曲形成弯曲空间24后，再将支撑结构23填充入该弯曲空间24中。
本发明实施例中的显示装置，通过设置支撑结构，可以有效支撑弯曲后的显示面板的弯曲区，提高了显示装置的良品率。
本发明实施例还提供了一种显示装置的制作方法。请参照图7，图7为本发明实施例提供的显示装置的制作方法的流程示意图。该方法包括：
步骤S101，提供背板，背板包括第一背板和第二背板。
其中，第一背板和第二背板起支撑设置在其上的部件的作用。
步骤S102，将显示面板的第一非弯曲区设置在第一背板上，并将显示面板的第二非弯曲区设置在第二背板上。
如图4或5所示，显示面板22的第一非弯曲区221设置在第一背板211上，即第一背板211用于承载第一非弯曲区221。显示面板22的第二非弯曲区222设置在第二背板212上，即第二背板212用于承载第二非弯曲区222。
步骤S103，在显示面板的弯曲区靠近背板的一侧涂布热固材料。
其中，热固材料在常温下处于凝胶状态，不会影响后续弯折弯曲区22。在一定温度下，该热固材料凝固，可以起支撑作用。在一实施例中，热固材料包括热固胶。
步骤S104，将显示面板朝背板方向弯折，使显示面板的弯曲区形成弯曲空间，并使第一背板和第二背板贴合。
显示面板22的弯曲区223形成弯曲空间24后，由于常温下，热固材料具有流动性，因此该热固材料将分散在整个弯曲空间24内。
在一实施例中，可以在第一背板211和第二背板212之间设置一胶体层25，以将第一背板211和第二背板212贴合在一起。
步骤S105，加热热固材料，使热固材料凝固支撑显示面板的弯曲区。
可以在80度至100度的温度下，加热该热固材料，使该热固材料凝固，即形成该支撑结构23。同时，上述温度下，也不会对显示装置2造成损害。
其中，如图5所示，受加工工艺以及热固材料自身特性的影响，经热固化处理后的热固材料，可能形成表面为不规则曲面形状的支撑结构23。且该支撑结构23部分填充该弯曲空间24，使该弯曲空间24也为与该支撑结构23匹配的不规则曲面形状。
本发明实施例的显示装置的制作方法，通过在显示装置弯曲前，在弯曲区靠近背板的一侧涂布热固材料，然后在弯曲后，加热该热固材料，形成支撑结构，提高了显示装置的良品率。
本发明实施例还提供了一种显示装置的制作方法。请参照图8，图8为本发明实施例提供的显示装置的制作方法的流程示意图。该方法包括：
步骤S201，提供背板，背板包括第一背板和第二背板。
其中，第一背板和第二背板起支撑设置在其上的部件的作用。
步骤S202，将显示面板的第一非弯曲区设置在第一背板上，并将显示面板的第二非弯曲区设置在第二背板上。
如图4或5所示，显示面板22的第一非弯曲区221设置在第一背板211上，即第一背板211用于承载第一非弯曲区221。显示面板22的第二非弯曲区222设置在第二背板212上，即第二背板212用于承载第二非弯曲区222。
步骤S203，将显示面板朝背板方向弯折，使显示面板的弯曲区形成弯曲空间，并使第一背板和第二背板贴合。
显示面板22朝背板21方向弯折后，该显示面板22的弯曲区223形成弯曲空间24。此时，第一背板211和第二背板212相对设置，可以在第一背板211和第二背板212之间设置一胶体层25，以将第一背板211和第二背板212贴合在一起。
步骤S204，将支撑结构填充在弯曲空间内，使支撑结构支撑显示面板的弯曲区。
在一实施例中，如图3所示，支撑结构23包括本体231和第一圆柱体232。该本体231的形状为与该弯曲空间24匹配的半圆柱形。第一圆柱体232设置在该本体2的一端。其中，本体231的截面半径r不小于所述弯曲空间24的截面半径。本体231可以完全撑起弯曲区223，并且在弯曲区223受到外界应力的时候，可以有效帮助弯曲区223缓解应力。第一圆柱体232的直径d1小于所述弯曲空间24的截面半径，便于支撑结构23插入该弯曲空间24中。支撑结构23完全插入弯曲空间24后，可以在第一圆柱体232侧滴入胶水，固定该支撑结构23。
在一实施例中，支撑结构23还包括第二圆柱体233。该第二圆柱体233设置在本体231远离第一圆柱体231的一侧。其中，第二圆柱体233的直径d2也小于弯曲空间24的截面半径。这样，在将支撑结构23插入弯曲空间24时，不需要对支撑结构23的两端进行区分，便于支撑结构23快速插入弯曲空间24中。支撑结构23完全插入弯曲空间24后，可以在第一圆柱体232和第二圆柱体233两侧均滴入胶水，固定该支撑结构23。
综上，如图2或3所示，可以设置支撑结构23的高度H等于弯曲空间24的高度。
在一实施例中，还可以采用如下方法，将支撑结构填充到弯曲空间中：
S1，提供一支撑件，支撑件包括所述支撑结构，以及设置在支撑结构一端的导入件；
S2，通过导入件，将支撑结构导入弯曲空间内；
S3，将导入件从支撑件中剥离，保留填充在弯曲空间的支撑结构。
如图9所示，还可以提供一支撑件3，支撑件3包括支撑结构23，以及设置在支撑结构23一端的导入件4。其中，导入件4可以设置成圆柱体形状，其截面直径小于弯曲空间24的截面半径，便于其插入该弯曲空间24中。
如图2所示，支撑结构23为与弯曲空间24匹配的半圆柱形状。该支撑结构23的截面半径为R，则该截面半径R不小于弯曲空间24的截面半径，即不小于弯曲空间的弯曲半径。这样，支撑结构23可以完全撑起弯曲区223，并且在弯曲区223受到外界应力的时候，可以有效帮助弯曲区223缓解应力。
该导入件4插入弯曲空间24中后，可以推动支撑结构23进入弯曲空间24。直至支撑结构23完全没入该弯曲空间24，则剥离该导入件4，只留下支撑结构23。
本发明实施例的显示装置的制作方法，通过在弯曲空间内填充形状匹配的支撑结构，支撑弯曲区，提高了显示装置的良品率。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
