柔性显示面板100是由柔软的材料制成，是一种可变型、可弯曲的显示装置。柔性显示面板主要用于显示彩色图像，同时结合柔性的触控面板，柔性显示设备也可以集成触控功能，广泛运用于例如手机、平板电脑及GPS等便携式电子设备。
具体地，柔性显示面板100包括第一部分101、第二部分102及第三部分103。第三部分103为一弯折部分，第一步分101及第二部分102为一对伸展部分，弯折部分位于一对伸展部分之间并连接该伸展部分。本实施例中，柔性显示面板100通过第三部分103折叠，所述弯折部分截面为圆弧。
在本揭示的第一实施例中，各所述第一承载体21包括一第一承载平台211与一第二承载平台212，所述第一承载平台211连接所述第一支架20，所述第二承载平台212连接所述第二支架30，所述第一间隙201形成于所述第一承载平台211与所述第二承载平台212之间。
其中，第一承载平台211和第二承载平台212之间的所述第一间隙201可通过滑动两个支架20、30 进行调节。在初始状态，第一承载平台211和第二承载平台212之间可以是靠合在一起，也可以是间隔一定的距离。本实施方式中，第一承载平台211和第二承载平台212之间在初始状态间隔一定的距离。所述初始状态是指柔性显示面板100处于伸展未进行测试状态，即柔性显示面板100未受到施力以使其弯曲的状态。
并且所述至少两第一承载体21之间具有一分隔间距T(示于图2)，使其中一所述柔性显示面板100的所述第三部分103所在的一水平轴线不接触另一所述柔性显示面板100的所述第一部分101与第二部分102所在的一水平轴线。即在两个第一承载体21之间维持足够的间距，从而使柔性显示面板100弯曲测试时不会相互接触。并且在本实施例中，所述第一承载体21的第一承载平台211和第二承载平台212上设置有一止滑垫25，所述柔性显示面板100设置于所述止滑垫25上，从而避免所述柔性显示面板100滑落。
在弯曲测试前，将柔性显示面板100放置在第一承载平台211和第二承载平台212上，并且将柔性显示面板100需要测试的部位对准第一承载平台211和第二承载平台212之间的位置放置，然后将柔性显示面板100分别与第一承载平台211和第二承载平台212固定。此时未弯曲挤压柔性显示面板100，柔性显示面板100处于伸展状态，第一支架20和第二支架30相互远离，且第一承载平台211和第二承载平台212所在平面均与基座10所在平面大致平行。
弯曲测试时，第一支架20和第二支架30在导轨40的带动下分别相向运动，即第一支架20沿着导轨的一方向(例如右方)运动，第二支架30沿着导轨的另一方向(例如左方)运动，即第一支架20和第二支架30在导轨40的带动下分别由两侧边方向朝向一中间方向移动，从而使得柔性显示面板100能够弯曲。由于在第一支架20和第二支架30之间设置有两个或是更多个第一承载体21，各第一承载体21之间层迭设置，在第一支架20和第二支架30分别相向运动时，分别位于多个第一承载体21上的多个柔性显示面板100同时可以进行弯曲测试，实现柔性显示面板的批量化测试。
请参阅图2，图2为根据本揭示第二实施例的柔性显示面板的弯曲测试装置示意图。本实施例与第一实施例的差别在于：柔性显示面板的弯曲测试装置更包括一第三支架50，相对于所述第二支架30的另一侧边平行设置，所述第二支架30与所述第三支架50之间层迭设置有至少两第二承载体31。
并且，各所述第二承载体31具有一第二间隙301，并且各所述第二承载体31包括一第三承载平台311与一第四承载平台312，所述第三承载平台311连接所述第二支架30，所述第四承载平台312连接所述第三支架50，所述第二间隙301形成于所述第三承载平台311与所述第四承载平台312之间。并且在本实施例中，所述第二承载体31的第三承载平台311与第四承载平台312上设置有一止滑垫35，所述柔性显示面板100设置于所述止滑垫35上，从而避免所述柔性显示面板100滑落。
弯曲测试时，第一支架和第二支架20、30在导轨40的带动下分别相向运动，而第三支架50可由导轨40带动下朝向所述第二支架30的方向水平移动，分别位于第一承载体21和第二承载体31上的多个柔性显示面板100同时可以进行弯曲测试，实现柔性显示面板的批量化测试。
更详细的说，在此实施例中，第一支架20及第三支架50为固定状态，导轨40带动第二支架30分别相对于第一支架20及第三支架50水平移动，当导轨40带动第二支架30向第一支架20的方向移动时，第一支架20及第二支架30间的柔性显示面板100进行弯曲测试，第三支架50及第二支架30间的柔性显示面板100则展开；而当导轨40带动第二支架30向第三支架50的方向移动时，第三支架50及第二支架30间的柔性显示面板100进行弯曲测试，第一支架20及第二支架30间的柔性显示面板100则展开。并且，第一支架20、第二支架和30和第三支架50于垂直方向的一支架长度越长，所能负载并进行弯曲测试的柔性显示面板100数量就越多，而第一支架20、第二支架和30和第三支架50于水平方向的支架数量越多(例如可包括第四支架、第五支架…以此类推) 所能负载并进行弯曲测试的柔性显示面板100数量就越多，可以实现同时进行弯曲测试的柔性显示面板100的数量加倍的效果。
请参阅图3，图3为根据本揭示第三实施例的柔性显示面板的弯曲测试装置示意图。本实施例与第一实施例的差别在于：所述第一承载体21更包括一第一延伸部22，所述第一延伸部22用于承载另一柔性显示面板110；以及所述第二承载体31更包括一第二延伸部32，所述第二延伸部用于承载另一柔性显示面板120。
更进一步的说，本实施例的原理在于所述第一承载体21及所述第二承载体31的一长度或宽度增加，如此所述第一承载体21及所述第二承载体31能够放置所述柔性显示面板100的一承载面积增加。相较于前述实施例，将使所述第一承载体21及所述第二承载体31能够供放置更多个柔性显示面板。进一步实现多个柔性显示面板的弯曲测试。
本揭示所提供的柔性显示面板的弯曲测试装置，通过使多个承载体层迭设置于支架上，实现柔性显示面板的批量化测试，改良了现有技术中一次只能针对单个柔性显示面板进行测试的缺陷。本揭示的柔性显示面板的弯曲测试装置可以实现同时进行多个柔性显示面板的弯曲测试。
以上所述是本揭示的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本揭示原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本揭示的保护范围。
