具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附图，对本公开实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本公开保护的范围。
除非另作定义，此处使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而是用来区分不同的组成部分。同样，“一个”、“一”或者“该”等类似词语也不表示数量限制，而是表示存在至少一个。“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。
在本文中，表述“连续延伸”可以表示显示基板的各部分之间是连续的，且多个部分可以成型为一体。例如，显示基板可以划分为显示部分和弯折部分，所述显示部分 和所述弯折部分是相接的，且在显示基板的横向方向上延伸。表述“连续延伸”也可以表示多个平面之间是连续的，且各平面之间彼此相接。
在本文中，表述“显示侧”表示显示面板显示画面的一侧，也可以说是人眼观看的一侧；所述“背侧”表示与显示面板的“显示侧”相反的另一侧，即不显示画面的一侧。
目前，为了使柔性显示面板实现全面屏显示的设计方案，通常将柔性显示面板的边缘设计为圆弧状的曲面，并将显示面板的部分显示基板朝向显示部分的背侧弯折，以使柔性显示面板满足边缘显示的需求。但是，在对显示基板进行弯折后，显示基板的弯折部分与边缘的曲面显示部分之间往往缺少必要的支撑和固定，进而导致显示面板的边缘容易受到外界环境的例如挤压或撞击等影响而发生移动和错位，从而对显示面板的结构以及性能造成严重的不良影响。此外，由于弯折后的显示基板的弯折部分与边缘的曲面显示部分之间缺少支撑，在对显示基板进行弯折时，显示基板的弯折角度难以确定以及固定，进而使显示基板的弯折效果难以得到保证，甚至会导致显示基板在弯折时发生死折现象。
本公开至少一个实施例提供一种显示面板，该显示面板通过在显示基板的弯折部分和曲面显示部分之间设置支撑部，可以对弯折部分和/或曲面显示部分分别提供稳定的支撑，从而避免或减小显示面板的边缘出现移动或错位等现象，进而提高显示面板的结构的稳定性，使显示面板的整体性能得到改善，提升显示面板的全面屏显示效果。
下面，将参考附图详细地说明本公开的一些实施例。应当注意的是，不同的附图中相同的附图标记将用于指代已描述的相同的元件。
本公开至少一个实施例提供一种显示面板，该显示面板包括显示基板和支撑部。该显示基板包括显示部分和位于显示部分至少一侧的弯折部分，显示部分包括主体显示部分和位于主体显示部分至少一侧的曲面显示部分，主体显示部分、曲面显示部分和弯折部分是连续延伸的，弯折部分被弯折且位于显示部分与显示面板的显示侧相反的背侧，且在弯折部分和曲面显示部分之间形成有容纳空间；支撑部至少部分位于弯折部分和曲面显示部分之间的容纳空间内，且分别与弯折部分和曲面显示部分接触。
图1A为本公开一些实施例提供的一种显示面板的部分结构的示意图。例如，如图1A所示，显示面板10包括显示基板和支撑部110。显示基板包括显示部分120和位于显示部分120至少一侧的弯折部分130，显示部分120包括主体显示部分140和位于主体显示部分140至少一侧的曲面显示部分150，主体显示部分140、曲面显示部分150和弯折部分130是连续延伸的，弯折部分130相对于显示部分120弯折且位于显示部分120与显示面板10的显示侧相反的背侧，且在弯折部分130和曲面显示部分150之间形成有容纳空间100。支撑部110至少部分位于弯折部分130和曲面显示部分150之间的容纳空间100内，且分别与弯折部分130和曲面显示部分150至少部分地接触。
显示面板10中，通过将支撑部110设置在弯折部分130和曲面显示部分150之间形成的容纳空间100内，使所述支撑部110分别与弯折部分130和曲面显示部分150接触，从而使弯折部分130和曲面显示部分150均可以得到稳定的支撑，避免或减小弯折部分130和曲面显示部分150之间发生移动或错位，进而提高显示面板10的结构的稳定性，改善显示面板10的整体性能，使显示面板10可以实现更好的全面屏显示效果。
在制备显示面板10的过程中，当对显示基板进行弯折时，由于支撑部110可以对显示基板弯折至显示部分120背侧的弯折部分130提供稳定的支撑，因而可以避免显示基板在弯折时出现死折的现象，进而提高制备的显示面板10的良率，有利于显示面板10实现大批量地生产及使用。
此外，通过设置支撑部110还可以进一步使显示基板的弯折部分130的弯折角度可控且保持固定，进而使显示基板可以按照预定的角度进行弯折，以达到预定的弯折效果。例如，支撑部110为长条形，在制备显示面板10的过程中，显示基板可以沿支撑部110的侧面周边进行弯折，以使显示基板的弯折角度及弯折效果可以保持稳定，进而使显示面板10的制备工艺可以得到优化，提高显示面板10的制备精度和良率，从而有利于显示面板10实现大批量地生产及使用。
需要说明的是，在图1A所示的本公开的一些实施例中，显示面板10的形状轮廓可以为方形、长方形或其他适合的形状；或者，在本公开的其他一些实施例中，根据不同的实际需求，显示面板10还可以采用其他例如三角形、五边形等规则或不规则的形状轮廓，本公开的实施例对此不作限制。
需要说明的是，在图1A所示的本公开的一些实施例中，示出了显示基板的位于显示部分120一侧的弯折部分130，而在本公开的其他一些实施例中，根据显示面板10的实际形状轮廓或不同的设计需求，显示面板10还可以包括位于显示部分120两侧或者更多侧的弯折部分。相应地，在图1A所示的本公开的一些实施例中，示出了显示基板的位于主体显示部分140两侧的曲面显示部分150，而在本公开的其他一些实施例中，显示面板10还可以包括位于主体显示部分单侧的曲面显示部分，或者位于主体显示部分多侧的多个曲面显示部分。本公开的实施例对此不作限制。
例如，如图1A所示，支撑部110包括与曲面显示部分150接触的第一侧面，曲面显示部分150包括与支撑部110接触的第二侧面，所述第一侧面和所述第二侧面的形状轮廓相同，例如支撑部110面向曲面显示部分150的一侧的形状轮廓与曲面显示部分150面向支撑部110的一侧(即曲面显示部分150的内侧)的形状轮廓相同。由此，支撑部110与曲面显示部分150之间可以更好地进行贴合，进而使支撑部110可以为曲面显示部分150提供更稳定的支撑，避免或减小曲面显示部分150出现移动、错位或变形等现象，进一步提升显示面板10的结构的稳定性。
例如，在曲面显示部分150的截面形状轮廓为1/4圆弧状的情形，支撑部110可以相应地设计为1/4圆柱型，以实现与曲面显示部分150之间更好地贴合，进而为曲面显示部分150提供更稳定的支撑。
例如，在图1A所示的本公开的一些实施例中，支撑部110的面向曲面显示部分150的第一侧面与曲面显示部分150面向支撑部110的第二侧面完全贴合，即支撑部110接触曲面显示部分150面向支撑部110的一侧的各个区域，以向曲面显示部分150的各个部分均能够提供均匀稳定的支撑。
在本公开的其他一些实施例中，支撑部还可以设置为与曲面显示部分面向支撑部的一侧的部分区域接触，即支撑部可以对曲面显示部分提供稳定的支撑即可，本公开的实施例对支撑部与曲面显示部分之间的接触面积的大小不作限制。相应地，在本公开的其他一些实施例中，支撑部也可以与弯折部分面向支撑部的一侧的部分区域接触，即支撑部可以对弯折部分提供稳定的支撑即可，本公开的实施例对支撑部与弯折部分之间的接触面积的大小不作限制。
在本公开的一些实施例中，如图1A所示，支撑部110与弯折部分130接触的部分为平面，且支撑部110的高度(即支撑部110在垂直于主体显示部分140的方向上的尺寸)与曲面显示部分150的高度(即曲面显示部分150在垂直于主体显示部分140的方向上的尺寸)相同，也就是说支撑部110与弯折部分130接触的一侧的表面与曲面显示部分150的边缘齐平。由此，在制备显示面板10的过程中，在弯折部分130沿曲面显示部分150的边缘弯折后，弯折部分130可以保持稳定的水平状态且与支撑部110面向弯折部分130的一侧完全贴合，进而可以减小弯折部分130与支撑部110之间的间隙，进一步增大弯折部分130与支撑部110之间的接触面积，从而使支撑部110对弯折部分130提供更加稳定的支撑。
在制备显示面板10的过程中，由于显示基板可以沿支撑部110的远离显示部分120的平面弯折且弯折后的显示基板的弯折部分130可以保持水平状态，因而显示基板的弯折终点及弯折角度均可以得到精确地控制，进而使显示基板达到理想的弯折效果。由此，在制备显示面板10的过程中，支撑部110的设置不仅可以避免显示基板弯折时出现死折的现象或发生破裂，还可以对显示基板的弯折工艺进行优化，使显示基板的弯折角度及弯折效果可以保持稳定，进而减小在显示基板弯折时可能产生的不必要的误差，进一步提升制备的显示面板10的精度和良率。
此外，由于弯折后的显示基板的弯折部分130以及支撑部110面向弯折部分130的一侧均处于水平面上(即处于平行于主体显示部分140的平面内)，进而在对弯折部分130、支撑部110和曲面显示部分150进行压合时，可以使用于压合的设备在垂直于主体显示部分140的方向上竖直运动，从而便于对显示面板10进行均匀地压合，改善显示面板10的压合效果，使显示面板10的制备工艺进一步得到优化。
例如，在图1A所示的本公开的一些实施例中，支撑部110与弯折部分130接触的部分以及支撑部110与曲面显示部分150接触的部分均具有粘性。由此，弯折部分130和曲面显示部分150均可以稳固地粘附于支撑部110上，使弯折部分130和曲面显示部分150之间的相对位置可以保持固定，进而进一步避免或减小弯折部分130和曲面显示部分150之间发生移动或错位，提升显示面板10的结构的稳定性。
例如，支撑部110与弯折部分130接触的部分以及支撑部110与曲面显示部分150 接触的部分的粘性可以设置为不低于2000gf/inch，以使弯折部分130和曲面显示部分150均可以稳固地粘附于支撑部110上，进而避免发生例如脱落等现象，进一步提升显示面板10的结构的稳定性。
例如，在本公开的一些实施例中，可以在支撑部110分别与弯折部分130以及曲面显示部分150接触的一侧设置例如粘性胶层，以使弯折部分130与支撑部110之间以及曲面显示部分150与支撑部110之间实现粘结；或者在本公开的一些实施例中，也可以将支撑部110自身设计为采用粘性材料制备，即支撑部110自身具有粘性，进而可以利用支撑部110自身的粘性使弯折部分130及曲面显示部分150分别粘附于支撑部110的表面，以通过支撑部110对弯折部分130及曲面显示部分150进行支撑和固定。本公开的实施例对此不作限制。
例如，在支撑部110采用粘性材料制备的情形，支撑部110可以采用例如泡棉等材质较软的粘性材料，以防止在将支撑部110粘附于显示基板上时对显示基板挤压力度过大，避免对显示基板造成损害。
为了使显示面板10实现全面屏显示的设计方案，在本公开的一些实施例中，如图1A所示，显示面板10还包括第一电路板160和柔性电路板170。例如，第一电路板160位于(例如固定于)主体显示部分140的背侧，柔性电路板170位于第一电路板160和弯折部分130之间，柔性电路板170的接触垫分别与第一电路板160的接触垫和弯折部分130的接触垫通过例如各向异性导电胶以实施绑定(bonding)从而建立电连接，进而使第一电路板160通过柔性电路板170与弯折部分130电连接。由此，第一电路板160和柔性电路板170通过弯折部分130实现与显示部分120的电连接，以对显示部分120的各像素单元进行信号传输，从而使显示面板10实现显示功能。
例如，如图1A所示，柔性电路板170可以为设置有驱动芯片180的覆晶薄膜(Chip on Film，COF)，进而显示面板10通过驱动芯片180提供的驱动信号来执行相应的显示操作。
例如，如图1A所示，为了使第一电路板160可以完全贴附于主体显示部分140的背侧，可以将连接第一电路板160和弯折部分130的柔性电路板170进行弯折。
例如，在如图1A所示的本公开的一些实施例中，支撑部110与弯折部分130接触 的部分为平面的情形，柔性电路板170的靠近弯折部分130的一侧可以弯折，以使柔性电路板170的至少一部分位于所述支撑部110与弯折部分130接触的部分上，进而在使第一电路板160平稳地贴附于主体显示部分140的背侧的情形下，经弯折的柔性电路板170也可以得到支撑部110的支撑以保持相对稳定的状态。
需要说明的是，在本公开的一些实施例中，第一电路板160可以为硬质材料的电路板，也可以为与柔性电路板170的材质相似的柔性电路板，本公开的实施例对此不作限制。
例如，在图1A所示的本公开的一些实施例中，显示基板包括柔性衬底基板。该柔性衬底基板的位于显示面板10的显示区域的部分上设置有呈阵列排布的多个像素单元，且该部分柔性衬底基板和设置在该部分柔性衬底基板上的多个像素单元被构造成显示部分120的显示器件结构层121，从而使显示面板10实现显示功能。例如，该柔性衬底基板的位于显示面板10的显示区域之外的部分朝向显示部分120的背侧弯折，以构成弯折部分130。
例如，如图1A所示，显示器件结构层121位于显示面板10的显示区域，显示器件结构层121中的每个像素单元可以包括发光元件、像素电路等，像素电路例如包括薄膜晶体管(TFT)等，发光元件例如包括有机发光二极管(OLED)或量子点发光二极管(QLED)。例如，薄膜晶体管包括有源层、栅极、源漏极；有机发光二极管包括驱动电极以及设置在驱动电极之间的发光层。例如，显示器件结构层121还包括设置在薄膜晶体管和有机发光二极管的各个电极层之间的多个绝缘层，例如多个绝缘层可以包括缓冲层、栅极绝缘层、中间介电层、平坦化层和像素界定层等。本公开的实施例对显示器件结构层121中的像素单元的结构不作限制。
图1B示出了图1A中的显示面板的示例性显示器件结构层的局部视图。如图1B所示，显示器件结构层121包括柔性衬底基板510、遮光部520、薄膜晶体管、有机发光二极管和包封层530。薄膜晶体管包括有源层541、栅极543、源漏极544。有机发光二极管包括第一驱动电极551、第二驱动电极552以及在第一驱动电极551和第二驱动电极552之间的发光层553。多个绝缘层设置在各个电极层之间。多个绝缘层可以包括缓冲层561、栅极绝缘层542、中间介电层562、平坦化层563和像素界定层554等。例如， 图1C所示的显示器件结构层121可以用于OLED显示面板。在本公开的其他一些实施例中，显示器件结构层121还可以包括其他的结构，本公开的实施例对此不作限制。
在本公开的一些实施例中，如图1A所示，显示基板的显示部分120的结构例如还可以包括与显示器件结构层121层叠设置的保护层123和散热层122。保护层123位于显示器件结构层121的显示侧，以对显示器件结构层121以及显示面板10的其他器件或功能层起到保护作用。例如，保护层123的材料可以为玻璃等无机材料或者聚酰亚胺等有机材料。散热层122位于显示器件结构层121的背侧，以驱散显示基板在显示过程中产生的热量。例如，散热层122的材料可以为具有良好的散热效果与延展性的金属材料。
例如，在本公开的其他一些实施例中，显示部分120的结构还可以包括例如触控电极层、偏光层或其他适合的结构层或功能层，本公开的实施例对此不作限制。需要说明的是，本公开的实施例对例如散热层122、保护层123或其他功能层的结构及设置方式不作限制。
需要说明的是，本公开的实施例对显示面板10中的部分结构进行说明，本公开实施例提供的显示面板10还可以包括其他所需的结构或器件，本公开的实施例对此不作限制。
在本公开的其他一些实施中，支撑部还可以与主体显示部分接触。
例如，在图1A所示的实施例的基础上，如图1C所示，显示面板20的支撑部210的至少一部分与主体显示部分240接触，进而增大支撑部210与显示部分220之间的接触面积。由此，在进一步使支撑部210对主体显示部分240提供支撑的情形下，还可以使支撑部210对弯折部分230和曲面显示部分250提供更加稳定的支撑，进而更有效地避免或减小弯折部分230和曲面显示部分250之间发生移动和错位，显著地提升显示面板20的结构的稳定性。
需要说明的是，图1C中所示的显示面板20除支撑部210与主体显示部分240接触的部分以外的其他结构及功能均与图1A中所示的显示面板10大体相同，在此不再赘述。
例如，在图1A和图1C所示的本公开的一些实施例中，显示面板10和显示面板20 可以为有机发光二极管显示面板或量子点发光二极管显示面板，或者也可以为其他类型的具有显示功能的柔性面板，本公开的实施例对此不作限制。
例如，显示面板10和显示面板20可以为电子纸、OLED面板、QLED面板、手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件，本公开的实施例对此不作限制。
本公开至少一个实施例还提供一种用于显示面板的治具，该治具包括载台。载台包括凹入的载物面和位于载物面至少一侧的支撑面；该显示面板的显示基板包括显示部分和位于显示部分至少一侧的弯折部分，显示部分包括主体显示部分和位于主体显示部分至少一侧的曲面显示部分，曲面显示部分分别与主体显示部分和弯折部分接触。载台的载物面用于容纳显示面板的显示部分，载物面包括第一主体表面和位于第一主体表面至少一侧的第二曲线凹面，第一主体表面用于容纳显示面板的主体显示部分，第二曲线凹面用于容纳显示面板的曲面显示部分，支撑面用于支撑显示面板的弯折部分，第一主体表面、第二曲线凹面以及支撑面是连续延伸的。
在本公开至少一个实施例提供的用于显示面板的治具中，通过对治具的载台进行例如凹坑开槽处理，使载台的载物面包括第一主体表面和第二曲线凹面，进而使载物面与显示面板的形状轮廓相配合，例如使第二曲线凹面与显示面板的圆弧状边缘相配合，以使显示面板的显示部分可以平稳地容纳于载台中。由此，例如在显示面板的制备过程中，显示面板的显示基板可以平稳地放置于载台上，使载台可以对显示基板提供稳定的支撑和固定，进而避免或减小显示基板在工艺过程中发生移动或错位，从而提升显示面板的制备工艺的稳定性和精度，提升显示面板的制备良率。
例如，在本公开上述实施例提供的治具用于对待弯折的显示基板进行弯折时，载台的载物面可以对显示基板的显示部分提供稳定的支撑，载台的支撑面可以对显示基板的弯折部分提供稳定的支撑，进而有效地避免或减小显示基板在弯折过程中发生位置移动或错位，从而改善显示基板的弯折效果，提升显示基板的弯折的精度和稳定性。由此，显示面板的制备工艺的稳定性和精度均可以得到显著提升，进而使显示面板的制备工艺得到优化，提高显示面板的制备良率。
图2为本公开一些实施例提供的一种用于显示面板的治具的载台的结构示意图。 例如，如图2所示，载台200包括凹入的载物面210和位于载物面210至少一侧的支撑面220。
例如，载物面210可以用于容纳显示面板的显示部分，例如可以用于容纳如图1A所示的显示面板10的显示部分120。载物面210包括第一主体表面211和位于第一主体表面211至少一侧的第二曲线凹面212。第一主体表面211用于容纳主体显示部分，例如可以用于容纳如图1A所示的显示面板10的主体显示部分140；第二曲线凹面212用于容纳曲面显示部分，例如可以用于容纳如图1A所示的显示面板10的曲面显示部分150。由此，载台200通过载物面210的凹陷设计，可以使显示基板的显示部分稳定地容纳于载台200中，从而使载台200在显示面板的加工或制备等过程中向显示基板的显示部分提供稳定的支撑，进而为显示面板提供稳定的加工环境。
例如，支撑面220用于支撑显示面板的待弯折到显示部分的背侧的弯折部分，例如可以用于支撑如图1A所示的显示面板10的弯折部分130。第一主体表面211、第二曲线凹面212、支撑面220是连续延伸的。由此，在对显示面板的制备或加工等过程中，支撑面220可以对显示基板的弯折部分提供稳定的支撑，进而为显示面板提供稳定的加工环境。
此外，在利用本公开实施例提供的治具制备显示面板的过程中，例如对显示面板的显示基板进行弯折时，由于支撑面220可以使显示基板的弯折部分处于稳定的水平状态，进而可以使与弯折部分连接的例如电路板(例如，如图1A中所示的第一电路板160和柔性电路板170)也保持在稳定的水平面上，从而可以使电路板被例如夹具准确地拾取，以便于后续的例如弯折等操作。
需要说明的是，在图2所示的载台200中，载台200包括位于载物面210两侧的支撑面220，载物面210包括位于第一主体表面211两侧的第二曲线凹面212，而在本公开的其他一些实施例中，治具中的载台还可以根据实际不同的需求，例如根据制备的显示面板的形状轮廓或工艺要求，设计为其他合适的结构，本公开的实施例对此不作限制。
例如，如图2所示，载台200的载物面210上开设有多个第一吸附孔230，多个第一吸附孔230用于使显示面板的显示部分吸附于载物面210上，例如可以用于使如图1A 所示的显示面板10的显示部分120吸附于载物面210上，进而在利用包括载台200的治具对显示面板进行加工时，可以使显示面板的显示部分稳固地固定于载物面210上，从而为显示面板提供稳定的加工环境，提升显示面板的制备工艺的精度和准确性，进一步提升制备的显示面板的良率。
例如，在本公开的一些实施例中，载台200中还可以设置有吸气通道，吸气通道与多个第一吸附孔230相通。例如，吸气通道的一侧与第一吸附孔230相通，吸气通道的另一侧与抽气机(例如气泵)相通，从而使得第一吸附孔230能产生吸附作用，以使显示基板的显示部分可以稳固地固定在载台200的载物面210上。需要说明的是，在本公开的其他一些实施例中，第一吸附孔230也可以通过其他的方式产生吸附作用，本公开的实施例对此不作限制。
需要说明的是，本公开的实施例对第一吸附孔230的设置个数不作限制，可以使显示面板的显示部分稳定地吸附于载台200的载物面210上即可。例如，由于第二曲线凹面212为曲面设计，因而为了保证显示面板的曲面显示部分可以稳固地吸附于第二曲线凹面212上，第二曲线凹面212上开设的第一吸附孔230的密度可以稍大于第一主体表面211上开设的第一吸附孔230的密度，本公开的实施例对此不作限制。
图3为本公开一些实施例提供的另一种用于显示面板的治具的载台的结构示意图。
例如，如图3所示，载台300包括主体部分340和位于主体部分340上的载物部分350，载物部分350包括载物面310和支撑面320，载物面310包括第一主体表面311和位于第一主体表面311两侧的第二曲线凹面312。主体部分340面向载物部分350的一面上开设有多个第二吸附孔360，多个第二吸附孔360用于使载物部分350吸附于主体部分340上。需要说明的是，图3所示的载台300的载物面310和支撑面320与图2所示的载台200的载物面210和支撑面220大体相同，在此不再赘述。
例如，在利用包括载台300的治具对显示面板进行制备或加工时，根据显示面板的不同形状轮廓，需要对载台300的载物部分350的载物面310进行加工处理，以使载物面310与相应的显示面板的形状轮廓相匹配，而无需对主体部分340的结构进行改动。由此，载台300的主体部分340可以被重复利用，进而使载台300的制备成本降低，且 进一步使包括载台300的治具的制备成本降低，从而使治具可以大范围地得到利用。
例如，本公开的一些实施例提供的治具还包括夹具，该夹具用于拾取显示面板的电路板，且被设置为可以带动电路板从第一位置运动至第二位置，所述第一位置位于支撑面远离载物面的一侧，所述第二位置与载台的第一主体表面相对，例如可从载台的横向侧面运动至载台的纵向侧面。例如，在本公开实施例提供的治具用于如图1A所示的显示面板10时，可以利用夹具拾取显示面板10的第一电路板160，然后将第一电路板160安装至显示部分120的背侧，例如安装至主体显示部分140的背侧。
例如，本公开的一些实施例提供的治具还包括压合部，该压合部被设置为可在垂直于载台的第一主体表面的方向上抵近弯折部分，以实施抵压操作。例如，在本公开实施例提供的治具用于如图1A所示的显示面板10时，可以利用该压合部在垂直于载台的第一主体表面的方向上抵压弯折部分130，以将曲面显示部分150、支撑部110和弯折部分130进行压合。
需要说明的是，本公开实施例提供的治具还可以包括其他的部件或功能件等，本公开的实施例对此不作限制。
下面以将本公开实施例提供的治具用于制备显示面板为例，对本公开实施例提供的治具的使用方法进行说明。

图4为本公开一些实施例提供的一种利用本公开实施例提供的治具制备显示面板的方法的流程图。例如，该制备方法包括以下步骤。
步骤S10：将待弯折的显示基板放置于载台上。
步骤S20：将支撑部放置于待弯折的显示基板的显示部分上。
步骤S30：使弯折部分弯折至显示部分的上方且与支撑部接触。
下面结合图5A-5F，以利用包括如图2所示的载台200的治具制备如图1A所示的显示面板10为例，对本公开实施例提供的显示面板的制备方法进行说明。例如，该制备方法包括以下步骤。
步骤S110：将待弯折的显示基板放置于载台200上。
例如，如图5A所示，待弯折的显示基板的显示部分120位于载物面210上，显示部分120的主体显示部分140与第一主体表面211接触，显示部分120的曲面显示部分150与第二曲线凹面212接触。待弯折的显示基板的弯折部分130位于支撑面220上。
步骤S120：提供第一电路板160，并将第一电路板160通过柔性电路板170与待弯折的显示基板的弯折部分130连接。
例如，如图5B所示，柔性电路板170的接触垫分别与第一电路板160的接触垫和弯折部分130的接触垫通过例如各向并性导电胶以实施绑定从而建立电连接，进而使第一电路板160通过柔性电路板170与待弯折的显示基板的弯折部分130连接。需要说明的是，在使弯折部分130、柔性电路板170和第一电路板160彼此相连时，柔性电路板170例如可以位于弯折部分130的上方，第一电路板160可以位于柔性电路板170的上方；或者，柔性电路板170可以位于弯折部分130的上方，第一电路板160可以位于柔性电路板170的下方，本公开的实施例对连接方式不作限制。
例如，结合图5B和图6A所示，显示部分120、弯折部分130、柔性电路板170和第一电路板160之间彼此电连接，进而可以通过柔性电路板170的驱动芯片180提供例如用于显示的驱动信号，以驱动显示部分120执行相应的显示操作，进而使显示面板10实现显示功能。
步骤S130：将支撑部110放置于待弯折的显示基板的显示部分120上。
例如，结合图5C和图6B所示，支撑部110放置于待弯折的显示基板的显示部分120上，并使支撑部110与曲面显示部分150接触。由此，在将弯折部分130弯折至显示基板的显示部分120的上方后，弯折部分130可以与支撑部110至少部分地接触。
步骤S140：用夹具410拾取第一电路板160，并使夹具410带动第一电路板160从支撑面220远离载物面210的一侧运动至载台200的第一主体表面211，例如从载台200的横向侧面运动至载台200的纵向侧面，以通过柔性电路板170的连接作用，使弯折部分130跟随所述夹具的运动而被弯折至显示部分120的上方。
例如，结合图5D和图5E所示，夹具410可以带动第一电路板160沿曲线R1从支撑面220远离载物面210的一侧运动至载台200的第一主体表面211，例如从载台200的横向侧面运动至载台200的纵向侧面，以将弯折部分130朝向显示部分120的背侧弯折。
例如，如图5E所示，弯折部分130可以沿支撑部110的边缘弯折，以与支撑部110至少部分地接触。
例如，如图5E所示，支撑部110与弯折部分130接触的部分为平面，柔性电路板170可以沿支撑部110远离曲面显示部分150的边缘弯折，以使第一电路板160贴附于主体显示部分140的背侧。
步骤S150：将压合部420放置于弯折部分130上，以将弯折部分130、支撑部110及曲面显示部分150抵靠着载物面210进行压合。
例如，如图5F所示，压合部420沿直线R2的方向抵近弯折部分130，以压合弯折部分130、支撑部110及曲面显示部分150，进而使弯折部分130、支撑部110及曲面显示部分150之间可以更好地贴合，从而使支撑部110为弯折部分130和曲面显示部分150提供更稳定的支撑。
本公开实施例提供的显示面板的制备方法可以在显示基板弯折时对显示基板提供稳定的支撑，并且使显示基板可以按照预定的弯折角度进行弯折，进而改善显示基板的弯折效果，并且提高显示面板的制备工艺的精确度和稳定性，提升制备的显示面板的良率。
