通常，柔性显示装置由很薄的柔性衬底制作形成。相对于传统显示器，柔性显示装置具有超薄、质量轻、耐用、储存量大、设计自由、可收卷等优点，已经广泛应用于显示产品上，特别是应用在移动通信设备上。目前，对于柔性显示装置的研究主要包括柔性有机电致发光显示器(Flexible Organic Light Emitting Diode，FOLED)、柔性电子墨水显示器又(也称作柔性电泳显示器Flexible Electrophoretic Display，FEPD)和柔性液晶显示器(Flexible Liquid Crystal Display，FLCD)。
上述各种柔性显示装置的显示面板的衬底为柔性衬底。柔性显示面板的制作工艺主要包括：将柔性衬底粘结在该刚性基板上；在柔性衬底上形成显示元件；以及将柔性显示面板和刚性基板剥离，以得到柔性显示面板。
发明内容
在将柔性显示面板和刚性基板剥离的过程中，若操作不当，会使得柔性衬底和显示元件变形并被破坏，另外，还会有分离残留物过多等问题，从而影响显示元件的性能，造成良率下降。
因此，提供一种能够有效地将柔性衬底和刚性基板剥离的柔性显示面板母板成为本领域亟待解决的技术问题。
本发明旨在至少解决现有技术中存在的技术问题之一，并且提出了一种显示面板母板以及一种显示面板的制作方法。

根据本发明的实施例，液体亲和度可调层可包括多个层叠设置的可调层单元。与柔性衬底接触的可调层单元的第一液体亲和度可调层与柔性衬底接触，并且与刚性基板接触的可调层单元的第二液体亲和度可调层与刚性基板接触。
根据本发明的实施例，所述显示面板母板还可包括显示元件，其设置在柔性衬底与液体亲和度可调层相背离的一侧。
根据本发明的另一方面，提供了一种显示面板的制作方法，包括：制备刚性基板和柔性衬底；对刚性基板和柔性衬底将要彼此相对的表面进行亲水处理；在刚性基板和柔性衬底中的至少一者的经亲水处理的表面上设置液体亲和度可调层；控制液体亲和度可调层具有第一液体亲和度，以使得液体亲和度可调层的表面形成亲水基团，并且将柔性衬底粘结在刚性基板上；在柔性衬底与刚性基板相背离的表面上形成显示元件；以及控制液体亲和度可调层具有第二液体亲和度，以使得液体亲和度可调层的表面形成疏水基团，并且将柔性衬底从刚性基板上剥离。
根据本发明的实施例，控制液体亲和度可调层具有第一液体亲和度的步骤可以包括使液体亲和度可调层处于第一温度，以使得液体亲和度可调层的表面形成亲水基团，并且控制液体亲和度可调层具有第二液体亲和度的步骤可以包括使液体亲和度可调层处于第二温度，以使得液体亲和度可调层的表面形成疏水基团。
根据本发明的实施例，控制液体亲和度可调层具有第一液体亲 和度的步骤可以包括使液体亲和度可调层处于第一酸碱度，以使得液体亲和度可调层的表面形成亲水基团，并且控制液体亲和度可调层具有第二液体亲和度的步骤可以包括使液体亲和度可调层处于第二酸碱度，以使得液体亲和度可调层的表面形成疏水基团。
根据本发明的实施例，控制液体亲和度可调层具有第一液体亲和度的步骤可以包括对液体亲和度可调层施加具有第一电场强度的电压，以使得液体亲和度可调层的表面形成亲水基团，并且控制液体亲和度可调层具有第二液体亲和度的步骤可以包括对液体亲和度可调层施加具有第二电场强度的电压，以使得液体亲和度可调层的表面形成疏水基团。
根据本发明的实施例，控制液体亲和度可调层具有第一液体亲和度的步骤可以包括利用具有第一强度的光线照射液体亲和度可调层，以使得液体亲和度可调层的表面形成亲水基团，并且控制液体亲和度可调层具有第二液体亲和度的步骤可以包括利用具体第二强度的光线照射液体亲和度可调层，以使得液体亲和度可调层的表面形成疏水基团。

具体实施方式
以下结合附图对本发明的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本发明，并不用于限制本发明。
图1为根据本发明实施例的显示面板母板的结构示意图，图2为进一步示出了图1所示的显示面板母板中的液体亲和度可调层的结构示意图。
参考图1，根据本发明实施例的显示面板母板100包括刚性基板110、柔性衬底120和设置在刚性基板110与柔性衬底120之间的液体亲和度可调层130。液体亲和度可调层130用于将柔性衬底120粘结在刚性基板110上。
需要说明的是，本发明没有对刚性基板110具体限定，例如，刚性基板110可以是，例如，硬质玻璃基板，或其他具有一定的强度的材料制成的基板，以承载位于其上的柔性衬底120。
另外需要说明的是，本发明所述的“显示面板母板”是指其尺寸符合制作形成后的显示面板的尺寸的包括刚性基板和柔性衬底的母版。因此不需要用于将大尺寸的基板切割形成若干个小尺寸的显示 面板的切割过程，而仅需要将制备了显示元件的柔性衬底从刚性基板上剥离即可形成显示面板。
图3示意地示出了根据本发明实施例的显示面板母板中的液体亲和度可调层具有亲水基团时与柔性衬底的粘附结构。图4示意地示出了根据本发明实施例的显示面板母板中的液体亲和度可调层具有疏水基团时与柔性衬底的剥离结构。
根据本发明实施例，当需要在柔性衬底120的表面形成显示元件140时，可以改变液体亲和度可调层130的液体亲和度，以形成亲水基团A(如图3所示)，使得柔性衬底120与刚性基板110能够牢固地粘结在一起，以有效避免显示元件的各个膜层出现脱落或者滑动现象。当需要将柔性衬底120与刚性基板110剥离时，可以改变液体亲和度可调层130的液体亲和度以形成疏水基团B(如图4所示)，使得液体亲和度可调层130粘性较差或者不具有粘性，从而有利于将柔性衬底120与刚性基板110剥离，提高剥离良率并有效保证显示面板的性能。
根据本发明的实施例，液体亲和度可调层130的材料应当满足在不同的条件下可以分别形成亲水基团A和疏水基团B，然而，本申请对于液体亲和度可调层130的材料没有具体限制，而是可以包括针对不同的处理条件相应的材料。对液体亲和度可调层130进行处理的方式包括(但不限于)采用不同的温度、酸碱度、电场强度、光照强度、反应液等对液体亲和度可调层130进行处理，以分别形成亲水基团A和疏水基团B，液体亲和度可调层130的材料可以包括对应于各种处理方式的不同的材料。
液体亲和度可调层130形成的亲水基团A与羟基(-OH)之间的吸附力较强，因此，根据本发明的实施例，预先对柔性衬底120和刚性基板110的表面进行亲水处理，以在柔性衬底120和刚性基板110的表面形成羟基(-OH)，从而改进包括亲水基团A的液体亲和度可调层130与柔性衬底120和刚性基板110的表面粘附性，使得刚性基板110与柔性衬底120牢固地粘结在一起，以便于在后续工艺中在柔性衬底120上形成显示元件140。
根据本发明的实施例，液体亲和度可调层130的材料可以包括在2014年中国化学会学术年会中由苏春平作者所阐述的树枝状铋涂层，具体可参考苏春平作者的《具有光控可逆超疏水/超亲水转换特性的树枝状铋涂层》，其阐述了采用简单的化学镀法合成了树枝状的铋涂层，该文献的全部公开内容以引用的方式合并于此。经硬脂酸表面改性后，该涂层表现出优异的超疏水性能(即，形成疏水基团B)和自清洁性能，其静态水接触角高达165°，并且滚动角低于5°。此外，所制备的超疏水铋涂层在紫外可见光光照50分钟后可以由超疏水变为超亲水性能(即，形成亲水基团A)。对于光照后的亲水表面通过硬脂酸再次改性又可以恢复到超疏水状态，从而实现在超疏水和超亲水之间的光控可逆转换。
根据本发明的实施例，液体亲和度可调层130的材料还可以包括经由N-异丙基丙烯酰胺制备形成的聚N-异丙基丙烯酰胺(pNIPA、pNIPAAm、pNIPAA或pNIPAm)热敏性聚合物，其可以经过热处理、施加电场等处理在亲水基团A和疏水基团B之间进行切换。
因此，在柔性衬底120上形成显示元件140之前，控制液体亲和度可调层130使其具有与刚性基板110和柔性衬底120上的羟基(-OH)较强吸附力(即，较强粘性)的亲水基团A，以便将刚性基板110与柔性衬底120牢固地连接在一起。当需要剥离刚性基板110与柔性衬底120时，控制液体亲和度可调层130使其具有粘性较差的疏水基团B，从而有利于将刚性基板110与柔性衬底120剥离，有效保证显示面板的良率。
图2为根据本发明另一实施例的显示面板母板的结构示意图。
参见图2，根据本实施例，液体亲和度可调层130可以包括一个可调层单元。可调层单元可以包括第一液体亲和度可调层131、第二液体亲和度可调层133和位于第一液体亲和度可调层131和第二液体亲和度可调层133之间的光热阻挡层132。第一液体亲和度可调层131位于光热阻挡层132和柔性衬底120之间以接触柔性衬底120，并且第二液体亲和度可调层133位于光热阻挡层132和刚性基板110之间以接触刚性基板110。
根据本发明的实施例，设置在第一液体亲和度可调层131和第二液体亲和度可调层133之间的光热阻挡层132可以对与柔性衬底120接触的第一液体亲和度可调层131以及与刚性基板110接触的第二液体亲和度可调层133分别进行控制。例如，可以改变与刚性基板110接触的第二液体亲和度可调层133的液体亲和度，使其一直具有亲水基团A，因此吸附力较强。当需要剥离刚性基板110与柔性衬底120时，可以仅改变与柔性衬底120接触的第一液体亲和度可调层131的液体亲和度，使其具有亲水基团B，从而实现仅仅将柔性衬底120与第一液体亲和度可调层131剥离，可进一步缩短工艺时间，提高制造效率。此外，当需要更换第二液体亲和度可调层133时，可以仅改变第二液体亲和度可调层133的液体亲和度，使其具有疏水基团B，以实现与刚性基板110剥离，便于更换新的第二液体亲和度可调层133。
当需要改变第一液体亲和度可调层131的液体亲和度时，可以对第一液体亲和度可调层131进行光照或者加热处理，使得第一液体亲和度可调层131的液体亲和度改变(例如，形成疏水基团B)。光热阻挡层132能够阻挡光线或热量传递至位于其另一侧的第二液体亲和度可调层133，因此不会改变第二液体亲和度可调层133的液体亲和度。
需要说明的是，本发明对于光热阻挡层132的具体结构并没有作出限定，其只要能够隔绝光线和热量即可。另外，应当理解的是，光热阻挡层132应当与第一液体亲和度可调层131以及第二液体亲和度可调层133之间粘性连接。根据本发明的实施例，第一液体亲和度可调层131、第二液体亲和度可调层133和光热阻挡层132可以一体形成，使得光热阻挡层132内嵌于第一液体亲和度可调层131与第二液体亲和度可调层133之间。
根据本发明的实施例，液体亲和度可调层130可以包括多个层叠设置的可调层单元(图中未示出)。与柔性衬底120接触的可调层单元的第一液体亲和度可调层131与柔性衬底120接触，并且与刚性基板110接触的可调层单元的第二液体亲和度可调层133与刚性基板 110接触。
通过设置多个可调层单元，能够增加液体亲和度可调层130的使用次数。当某一层可调层单元因为多次使用而损坏时，可以利用下一层的可调层单元，从而缩短制造时间，提高制作良率。
根据本发明的实施例，显示面板母板100还可以包括设置在柔性衬底120与液体亲和度可调层130相背离的一侧上的显示元件140。
在柔性衬底120上形成显示元件140时，柔性衬底120与刚性基板110通过具有亲水基团A的液体亲和度可调层130牢固地粘结在一起，从而有效保证在形成显示元件140的过程(例如，镀膜过程)中，各个膜层能够准确地处于其设计位置，确保了显示元件140的性能。

根据本实施例，例如，可以利用容纳槽(图中未示出)容纳不同酸碱度的溶液，并且可以将液体亲和度可调层放置于该容纳槽中，改变液体亲和度可调层所处的酸碱度条件。
根据本发明的实施例，控制液体亲和度可调层具有第一液体亲和度的步骤可以包括对液体亲和度可调层施加具有第一电场强度的电压，以使得液体亲和度可调层的表面形成亲水基团，并且控制液体亲和度可调层具有第二液体亲和度的步骤可以包括对液体亲和度可调层施加具有第二电场强度的电压，以使得液体亲和度可调层的表面形成疏水基团。
也就是说，在步骤S400中，对液体亲和度可调层施加具有第一电场强度的电压，以使得液体亲和度可调层的表面形成亲水基团。此外，在步骤S600中，对液体亲和度可调层施加具有第二电场强度的电压，以使得液体亲和度可调层的表面形成疏水基团。
根据本实施例，例如，可以利用相对设置的两个电极向液体亲和度可调层施加电压。通过改变施加电压的电场强度来改变液体亲和度可调层的液体亲和度，操作方便。
根据本发明的实施例，控制液体亲和度可调层具有第一液体亲和度的步骤可以包括利用具有第一强度的光线照射液体亲和度可调层，以使得液体亲和度可调层的表面形成亲水基团，并且控制液体亲和度可调层具有第二液体亲和度的步骤可以包括利用具体第二强度的光线照射液体亲和度可调层，以使得液体亲和度可调层的表面形成疏水基团。

根据本实施例，例如，可以将该液体亲和度可调层置于不同的反应液中，以改变液体亲和度可调层液体亲和度，操作方便。
可以理解的是，以上实施方式仅仅是为了说明本发明的原理而采用的示例性实施方式，然而本发明并不局限于此。对于本领域内的普通技术人员而言，在不脱离本发明的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也视为本发明的保护范围。
