附图说明
通过结合附图进行的以下描述，本发明的实施例的上述和其它方面、特点和优点将变得更加清楚，附图中：
图1是根据本发明的实施例的柔性OLED显示器的分离方法的制程图；
图2是根据本发明的弹性网板在柔性OLED显示器上的投影的示意图。
具体实施方式
以下，将参照附图来详细描述本发明的实施例。然而，可以以许多不同的形式来实施本发明，并且本发明不应该被解释为限制于这里阐述的具体实施例。相反，提供这些实施例是为了解释本发明的原理及其实际应用，从而使本领域的其他技术人员能够理解本发明的各种实施例和适合于特定预期应用的各种修改。
在附图中，为了清楚器件，夸大了层和区域的厚度。相同的标号在整个说明书和附图中表示相同的元器件。
图1是根据本发明的实施例的柔性OLED显示器的分离方法的制程图。
具体地，根据本发明的实施例的柔性OLED显示器的分离方法包括步骤一至步骤六。
步骤一：参照图1中的(a)图，利用真空吸附台100真空吸附经激光剥离后的OLED显示组件200。
具体地，作为一种实施方式，OLED显示组件200可以包括被真空吸附台真空吸附的硬质基板210以及形成于硬质基板210上的柔性OLED显示器220。在经过激光剥离之后，硬质基板210与柔性OLED显示器220之间存在微小的间隙和/或气泡。
此外，需要说明的是，本实施例的硬质基板210可例如是玻璃基板，但本发明并不限制于此，例如也可以是硬质的树脂基板等。
进一步地，作为本发明的一种实施方式，柔性OLED显示器220可以包括： 柔性基底221，形成于硬质基板210上；薄膜晶体管层222，形成于柔性基底221上；有机发光二极管层223，形成于薄膜晶体管层222上；薄膜封装层224，形成于有机发光二极管层223和薄膜晶体管层222上，以封装有机发光二极管层223。这里，柔性OLED显示器220的结构仅是一种示例，本发明的柔性OLED显示器的结构并不局限于此。
柔性基底221可以采用聚酰亚胺材料制成；但本发明并不限制于此。当经激光剥离之后，柔性基底221与硬质基板210之间存在微小间隙和/或气泡。
进行完步骤一之后，进行步骤二。
步骤二：参照图1中的(b)图，使弹性网板300面向柔性OLED显示器220。
具体地，作为一种实施方式，弹性网板300可以包括板本体310以及设置于板本体310内的两个滚轮320，两个滚轮320靠近板本体310的面向柔性OLED显示器220的第一表面(未示出)。这里，本实施例中的弹性网板300的结构仅是一种示例，本发明的弹性网板的结构并不局限于此。
此外，本实施例中示出了两个滚轮320，但是本发明并不对滚轮320的数量作具体限定，可以根据实际需求对滚轮320的数量进行设置，但最少需要两个。
进一步地，板本体310可以由聚对苯二甲酸乙二醇酯材料制成，但本发明并不限制于此，例如也可以采用其他的弹性材料制成。
此外，两个滚轮320可以完全相同，并且每个滚轮320可以由橡胶材料制成，但本发明并不限制于此，例如滚轮320的主体可以由钢材制成，在该主体之外覆盖橡胶等材料。
此外，弹性网板300面向柔性OLED显示器220之后，弹性网板300在柔性OLED显示器220上的投影完全位于柔性OLED显示器220内。进一步地，如图2所示，弹性网板300在柔性OLED显示器220上的投影的第一边沿(即图2中的左侧边沿)与其邻近的柔性OLED显示器220的边沿(即图2中的左侧边沿)之间的距离和弹性网板300在柔性OLED显示器220上的投影的第二 边沿(即图2中的右侧边沿)与其邻近的柔性OLED显示器220的边沿(即图2中的右侧边沿)之间的距离相等，这里所述第一边沿与所述第二边沿相对。
进一步地，弹性网板300在柔性OLED显示器220上的投影的第三边沿(即图2中的上侧边沿)与其邻近的柔性OLED显示器220的边沿(即图2中的上侧边沿)之间的距离和弹性网板300在柔性OLED显示器220上的投影的第四边沿(即图2中的下侧边沿)与其邻近的柔性OLED显示器220的边沿(即图2中的下侧边沿)之间的距离相等，这里所述第三边沿与所述第四边沿相对。
此外，两个滚轮320彼此紧靠且相对于所述第一表面的中央部分。进一步地，两个滚轮320彼此紧靠且相对于柔性OLED显示器220的中央部分，但本发明并不限制于此。这样，可以使滚轮320施加均匀化的压力。
进行完步骤二之后，进行步骤三。
步骤三：参照图1中的(c)图，滚轮320朝向柔性OLED显示器220移动，以带动所述第一表面的部分向柔性OLED显示器220移动并与柔性OLED显示器220接触。
也就是说，在该步骤三中，板本体310不移动，仅移动滚轮320。由于板本体310具有弹性，因此滚轮320可以带动板本体310的部分接触柔性OLED显示器220，并对柔性OLED显示器220施加压力。
进行完步骤三之后，进行步骤四。
步骤四：参照图1中的(d)图，两个滚轮320彼此背向移动并保持对柔性OLED显示器220的压力，以使柔性OLED显示器220与硬质基板210之间的微小间隙和/或气泡向外排出，从而柔性OLED显示器220与硬质基板210分离。
在该步骤四中，柔性OLED显示器220与硬质基板210之间的分离为极微小分离，即肉眼无法看出的分离。
进行完步骤四之后，进行步骤五。
步骤五：参照图1中的(e)图，板本体310朝向柔性OLED显示器220 移动，以使板本体310的第一表面全部与柔性OLED显示器220接触并真空吸附柔性OLED显示器220。
在该步骤五中，板本体310的第一表面全部与柔性OLED显示器220接触并真空吸附柔性OLED显示器220的过程中，不会使柔性OLED显示器220与硬质基板210重新结合，即在这个过程中柔性OLED显示器220与硬质基板210之间依旧保持极微小分离。
进行完步骤五之后，进行步骤六。
步骤六：参照图1中的(f)图，真空吸附台100真空吸附着硬质基板210沿着远离柔性OLED显示器220的方向移动，以使柔性OLED显示器220与硬质基板210彼此远离。
经过步骤六之后，可以使柔性OLED显示器220与硬质基板210完全原理，从而完成柔性OLED显示器220的分离。
综上所述，根据本发明的实施例的柔性OLED显示器的分离方法，在节拍时间(tack time)、良率以及保护柔性OLED显示器等方面具有良好的效果。
虽然已经参照特定实施例示出并描述了本发明，但是本领域的技术人员将理解：在不脱离由权利要求及其等同物限定的本发明的精神和范围的情况下，可在此进行形式和细节上的各种变化。
