实施本发明的方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本发明一部分实施例，而不是全部的实 施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本实施例的柔性折叠显示屏制备方法，包括：在柔性屏体端部，设置固化装配区域；在固化装配区域内布设控制IC电路；在固化装配区域之外的柔性屏体作为显示区域，剥离与显示区域结合的玻璃基板；调整玻璃基板尺寸，与固化装配区域适配。
具体地，在玻璃基板上形成柔性屏体，该柔性屏体包括显示区域和位于柔性屏体的端部处的固化装配区域，在固化装配区域内布设控制IC电路，剥离掉与显示区域结合的玻璃基板。需要说明的是，控制IC电路可以布设在固化装配区域的内部，也可以布设在固化装配区域内的上表面处，本发明对此不作限制。
本实施例的柔性折叠显示屏制备方法，可以充分利用现有的柔性屏体特性，充分利用现有的显示屏幕产品，形成符合市场需求的柔性显示屏幕。通过将不易弯曲和折叠的部件集中在不需要进行剥离的柔性屏体的固化装配区域，保证了柔性屏体与玻璃基板和控制IC电路的剥离良品率，不会造成屏体电路、驱动芯片受损。
上述的柔性屏体的端部，可以是柔性屏体延伸方向上的一个边缘，或者是柔性屏体延伸方向上的相对(的两个)边缘，或者是一个边缘的一部分，或者相对边缘的一部分，或者是一个边缘的间隔部分，或者是相对边缘的间隔部分。
上述的间隔部分，是指彼此间隔开的两个或更多个部分。
本实施例的柔性折叠显示屏制备方法，采用激光剥离技术，剥离与显示区域结合的玻璃基板。
本实施例的柔性折叠显示屏制备方法，利用激光的准直性和高能可调特点，可以完成精确的层间分离，分离表面平整。
本实施例的柔性折叠显示屏制备方法，还包括：在固化装配区域的玻璃基板上设置触控输入区域。
上述的触控输入区域，可以设置在玻璃基板的任何位置处，例如，在靠近柔性屏体的玻璃基板的一侧与显示区域之间，或者在远离柔性屏体的玻璃基板的另 一侧处，本发明对此不作限制。
本实施例的柔性折叠显示屏制备方法，可以充分利用仅起到支撑作用的玻璃基板，形成固定的交互信号输入结构或输入电路，保证了在不增加额外空间结构的基础上获得固定的输入接口。
上述的设置触控输入区域，包括相应的电路设置和电路连接。
另外，在现有技术中，在显示区域边缘走线的信号线线束形成的单色条带，进一步在柔性屏体边缘形成单色边框，如黑色，影响了柔性屏体的整体显示效果。针对这一缺陷，本实施例的柔性折叠显示屏制备方法，还包括：在显示区域的边缘设置像素稀疏区域，像素稀疏区域内布设的像素单元的像素单元密度小于像素稀疏区域外的像素单元的像素单元密度，像素稀疏区域内的相邻像素单元的间距适应信号线的外径；在像素稀疏区域的像素单元间均匀布设信号线。
上述像素单元密度，是指单位面积内布设的像素单元的数量。
本实施例的柔性折叠显示屏制备方法，利用降低显示区域的柔性屏体边缘的像素单元密度，在显示区域边缘利用像素单元分割出可以用于信号线走线的细小走线空间，由于这些走线空间分布有序，线束中的信号线可以尽可能均匀分布，同时像素单元发光产生的衍射和亮度效果可以有效降低单一信号线的差异反射。这样就在显示区域边缘消除了单色条带，形成无边框效果，显著提升了柔性屏体的整体显示效果。
本实施例的柔性折叠显示屏制备方法，还包括：在像素稀疏区域中，相邻像素单元组成像素矩阵，像素矩阵均匀布设，像素稀疏区域中相邻像素矩阵的间距适应信号线的外径；在像素矩阵间均匀布设信号线。
上述像素矩阵可以由相邻的像素单元组成三角形、矩形、菱形或其他多边形的轮廓。
本实施例的柔性折叠显示屏制备方法，可以在像素稀疏区域的局部调整像素单元密度，适应信号线的数量和走线距离。
本实施例的柔性折叠显示屏制备方法，还包括：在像素稀疏区域中，自内侧(朝向柔性屏体中部的一侧，垂直或不垂直)向外侧(朝向柔性屏体边缘的一侧， 垂直或不垂直)像素单元密度逐渐变小，像素稀疏区域中，像素单元间距适应信号线外径的同时，像素单元间距逐渐变大；在像素稀疏区域的像素单元间均匀布设信号线。
像素稀疏区域外的像素单元密度大于像素稀疏区域内侧的像素单元密度，并且像素稀疏区域内侧的像素单元密度大于像素稀疏区域外侧的像素单元密度。
本实施例的柔性折叠显示屏制备方法，可以在保证显示效果的前提下，在像素稀疏区域中形成较稀疏走线区域和较密集走线区域，保证信号线束的合理走线，在最边缘处的密集走线的视觉效果质量最低，但仍可以保证不形成单色条带的边框，实现无框效果。
图1为本发明柔性折叠显示屏一实施例的主视剖视图。如图1所示，本发明实施例的一种柔性折叠显示屏包括柔性屏体01、玻璃基板02和控制IC电路03，在柔性屏体01的端部划定固化装配区域11，在固化装配区域11之外的柔性屏体作为显示区域，在固化装配区域11顶部设置控制IC电路03，在固化装配区域11底部设置玻璃基板02。

像素稀疏区域12内的像素单元19间距适应信号线的外径，相等或略大于信号线的外径。
在像素稀疏区域12的像素单元19间均匀布设信号线。
图3为本发明柔性折叠显示屏另一实施例中显示区域的柔性屏体的一种像素单元排列的结构示意图(俯视视角)。如图3所示，在上一实施例的基本结构保持不变的基础上，在像素稀疏区域12，若干相邻的像素单元19组成像素矩阵13，像素矩阵13均匀布设。
像素稀疏区域12内的像素矩阵的相邻间距适应信号线的外径。
像素稀疏区域12内的像素矩阵13间均匀布设信号线。
图4为本发明柔性折叠显示屏再一实施例中显示区域的柔性屏体的一种像素排列的结构示意图(俯视视角)。如图4所示，在上一实施例的基本结构保持不变的基础上，在像素稀疏区域12，自内侧向外侧像素单元19密度逐渐变小。像素稀疏区域12内的像素单元的间距，自内侧向外侧，像素单元间距适应信号线外径的同时，像素单元间距逐渐变大。
在像素稀疏区域的像素单元间均匀布设信号线。
图5为本发明柔性折叠显示屏制备方法的流程图。如图5所示，该方法包括如下步骤：
510：在玻璃基板上形成柔性屏体，该柔性屏体包括显示区域和在该柔性屏体的端部处的固化装配区域。
520：在固化装配区域内布设控制IC电路。
530：剥离与显示区域对应的玻璃基板。
在本发明实施例中，对玻璃基板的尺寸进行调整，例如将与显示区域对应的玻璃基板剥离，使剥离后剩余的玻璃基板与固化装配区域适配。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换等，均应包含在本发明的保护范围之内。
