Description
本申请要求于2019年11月28日提交中国专利局、申请号为201911190796.0、发明名称为“一种柔性显示模组和柔性显示装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
本申请涉及显示面板技术领域，尤其涉及一种柔性显示模组和柔性显示装置。
柔性有源矩阵发光二极管(Active-matrix organic light-emitting diode，即AMOLED)是未来极具竞争优势的柔性显示技术，通过将柔性显示介质电子元件与材料安装在有柔性或可弯曲的基板上，使得显示器具有能够弯曲或卷曲成任意形状的特性，并具有轻、薄且方便携带等特点，尤其是其可折叠性，使得面板可以有更大的显示区域且不会占据更大的空间，另外，其可以搭配不同外形的盖板，即可实现不同样式的显示产品，有助于提高该产品的市场占有率。
目前比较常见的柔性显示屏应用方案为，将显示面板的绑定端进行产品弯折，将绑定端弯折至显示面板的背部并与位于背部的柔性电路板进行绑定，以减少显示面板的边框区，并且增加显示面板的有效显示区域的占比。
然而，采用上述柔性显示屏应用方案时可能会遇到以下的状况：因柔性显示屏的材料均是柔软的，在绑定端弯折至显示面板的背部后形成圆弧易变形且不稳定，绑定端弯折制程难度较大，且在后面的制程工序中容易误触压到显示面板背部的绑定端造成显示面板的线路断裂。因此，提供一种更加可靠的可弯折显示装置成为了一项重要课题。

如图1至图5所示，本申请实施例提供了一种柔性显示模组1，包括柔性显示面板2、电路板3和面板保护结构4；柔性显示面板2包括有效显示部5和绑定部6；面板保护结构4位于有效显示部5的背部，面板保护结构4在远离有效显示部5的一侧设有沉槽7；其中，绑定部6设于沉槽7内，并与有效显示部5电性连接，且电路板3设于沉槽7内，并与绑定部6电性连接。
具体的，面板保护结构4的材料为刚性材料，例如铝合金或不锈钢，当然，此处对面板保护结构4的具体材料不做限制；电路板3和绑定部6可以通过粘贴胶贴覆在沉槽7内，当然，还可以通过其他有效的方式固定在沉槽7内，此处不做限制。
具体的，如图5所示，有效显示部5从下到上包括第一背板8、柔性基板9以及依次设置在柔性基板9上的TFT（Thin Film Transistor，薄膜晶体管）阵列层10、发光功能层11和薄膜封装层12；且有效显示部5按照不可弯折的部分以及可弯折的部分来划分，可以分为第一平板部13、第二平板部14以及连接第一平板部13和第二平板部14的折叠部15，其中，第一平板部13和第二平板部14为不可弯折的部分，折叠部15为可弯折的部分，第一平板部13可通过折叠部15弯折至与第二平板部14折叠设置；绑定部6包括从有效显示部5延伸出来的柔性基板9、TFT阵列层10和薄膜封装层12，位于绑定部6的TFT阵列层10与电路板3电连接。若柔性显示面板2为触控式的柔性显示面板2，则柔性显示面板2还包括触屏模组16，触屏模组16包括依次设置在薄膜封装层12上的触摸层17、偏光层18和盖板19。
具体的，第一背板8仅设置在第一平板部13和第二平板部14中的柔性基板9的背部；面板保护结构4设置在第一平板部13中的第一背板8上，且位于第一背板8远离柔性基板9的一侧；需要说明的是，面板保护结构4还可以设置在第二平板部14中的第一背板8上（图中未示出），此时，沉槽7仅设置在对应第一平板部13设置的面板保护结构4上，而对应第二平板部14设置的面板保护结构4是为了保持柔性显示模组1的背部的平整性或者是为了与整机装配时的底壳结构设计相匹配。
本实施例中，在柔性显示面板2的有效显示部5的背部设置了面板保护结构4，且面板保护结构4上设有沉槽7，相互电连接的电路板3和绑定部6均设置在沉槽7内，一方面，面板保护结构4为刚性结构，可以避免有效显示部5正面的按压操作导致有效显示部5内凹变形而影响电路板3和绑定部6之间的线路以及绑定部6与有效显示部5之间的线路连接稳定性，另一方面，电路板3和绑定部6均设置在沉槽7内，可以避免柔性显示模组1的背部在放置时或进行其他制程时直接触压到电路板3和绑定部6，从而减小电路板3和绑定部6之间的线路以及绑定部6上的线路断裂的概率。
在一实施例中，如图1所示，柔性显示面板2还包括连接有效显示部5和绑定部6的弯折部20；面板保护结构4包括靠近弯折部20的第一侧壁21，沉槽7靠近弯折部20的一侧延伸至第一侧壁21，绑定部6通过弯折部20弯折在沉槽7内。
具体的，第一平板部13与绑定部6通过弯折部20连接。
具体的，弯折部20呈圆弧形弯折状态；弯折部20包括从有效显示部5延伸出来的柔性基板9、TFT阵列层10和薄膜封装层12；绑定部6、弯折部20和有效显示部5中相同的结构均在同一制程中形成。
具体的，绑定部6通过弯折部20弯折到有效显示部5的背部后，绑定部6可以直接采用粘贴胶贴覆在沉槽7内，也可以在沉槽7内设置背板并将绑定部6贴覆在背板上，具体根据面板保护结构4的厚度以及沉槽7的深度来决定是否需要在沉槽7内设置背板；无论采用哪种方式将绑定部6设置在沉槽7内，绑定部6与有效显示部5基本平行，且绑定部6与柔性基板9之间的间距与弯折部20的弯折半径相匹配，即位于绑定部6与柔性基板9之间的所有结构的总厚度等于弯折部20内侧弯折面的弯折直径。
本实施例中，沉槽7靠近弯折部20的一侧延伸至第一侧壁21，使得第一侧壁21对应弯折部20的部分的高度较小，有利于弯折部20的弯折操作，且有利于绑定部6全部位于沉槽7内，可以有效的保护绑定部6。
在一实施例中，如图4所示，第一侧壁21与弯折部20对应的部分位于弯折部20的内侧，且与弯折部20触接，弯折部20靠近绑定部6的一端位于沉槽7内。
具体的，第一侧壁21位于弯折部20的内侧的部分还可以设置弧形凸起结构（图中未示出），且弧形凸起结构与弯折部20的内侧贴合设置。
具体的，第一侧壁21部分位于弯折部20的内侧，即面板保护结构4还对应与第一平板部13连接的弯折部20设置。
本实施例中，一方面，弯折部20在弯折过程中可以绕对应的第一侧壁21弯折，有利于实现弯折制程，避免弯折部20变形不稳定；另一方面，弯折部20弯折后，靠近绑定部6的一端位于沉槽7内，有利于保护弯折部20，可以避免柔性显示模组1的背部在放置时或进行其他制程时直接触压到这部分弯折部20。
在一实施例中，沉槽7的深度大于绑定部6和电路板3中任意一个的厚度。具体的，电路板3包括柔性线路板24和覆晶薄膜25，其中，覆晶薄膜25的一端与绑定部6远离弯折部20的一端绑定，另一端与柔性线路板24电连接；沉槽7的深度大于覆晶薄膜25与绑定部6绑定位置的总厚度。需要说明的是，柔性显示面板2的其他组件也可以弯折至沉槽7内，例如，柔性显示面板2为触控式的柔性显示面板2时，从触摸层17延伸的线路可以弯折至柔性显示面板2的背面并设于沉槽7内，沉槽7的厚度也大于从触摸层17延伸的线路的厚度，即沉槽7的厚度大于置于沉槽7内的任意一个结构的厚度或任意多个叠加结构的总厚度。
具体的，沉槽7内还可以设置背板23，背板23位于绑定部6靠近有效显示部5的一侧，沉槽7的深度大于绑定部6和背板23的总厚度；其中，背板23用于支撑绑定部6，并控制绑定部6与柔性基板9之间的间距，从而使弯折部20保持稳定的弯折状态。
本实施例中，沉槽7的厚度大于绑定部6的高度以及电路板3的高度，可以在柔性显示模组1的背部朝向机台放置或进行其他制程时起到有效的支撑作用，避免绑定部6和电路板3直接与机台接触或者被其他操作误触压到，从而减小电路板3和绑定部6之间的线路以及绑定部6上的线路断裂的概率。
在一实施例中，面板保护结构4还包括与第一侧壁21相邻设置的第二侧壁26和第三侧壁27，以及与第一侧壁21相对设置的第四侧壁28；第二侧壁26和第三侧壁27与第四侧壁28也相邻设置；第二侧壁26、第三侧壁27和第四侧壁28均为倾斜面（图中未示出），且倾斜角度大于0°且小于90°。
具体的，第二侧壁26、第三侧壁27和第四侧壁28可以通过拔模式设计或倒梯形、燕尾型等设计形成倾斜面。
本实施例中，柔性显示模组1在整机装配时需与对应的底壳进行整机装配从而形成完整的柔性显示装置36，由于面板保护结构4向柔性显示模组1的背面凸出，底壳上一般设有与凸出的面板保护结构4相对应的凹槽，凹槽的大小和形状与面板保护结构4相匹配，且凹槽与第二侧壁26、第三侧壁27和第四侧壁28对应的内壁也设计为与之匹配的倾斜面，使得柔性显示模组1与底壳整机装配时，柔性显示模组1可以通过面板保护结构4的第二侧壁26、第三侧壁27和第四侧壁28滑入底壳中，操作简单，组装方便，可以节省整机装配的时间，提高生产效率。
在一实施例中，沉槽7的形状与设于沉槽7内的电路板3、绑定部6以及其他组件共同构成的整体结构的形状相同，且沉槽7的侧壁与相邻的电路板3或绑定部6或其他组件之间设有安全间距，以避免柔性显示模组1在使用中沉槽7的侧壁与电路板3或绑定部6之间发生挤压而影响线路连接的稳定性，且避免挤压破坏材质较柔软的绑定部6。
在一实施例中，如图8所示，柔性显示模组1还包括保护膜29，保护膜29位于面板保护结构4远离有效显示部5的一侧，且保护膜29至少覆盖在沉槽7上。
具体的，保护膜29可以仅覆盖在面板保护结构4上，也可以覆盖在柔性显示面板2的背部和面板保护结构4上，此处不做限制。
本实施例中，保护膜29覆盖在沉槽7上，可以进一步保护沉槽7内的电路板3和绑定部6，避免柔性显示模组1的背部在放置时或进行其他制程时直接触压到电路板3和绑定部6，从而减小电路板3和绑定部6之间的线路以及绑定部6上的线路断裂的概率。
如图6和图7所示，本申请实施例提供了一种柔性显示模组，与上述实施例不同的在于，面板保护结构4包括金属薄板30和金属片31；金属薄板30设置在第一平板部13的背部，沉槽7设置在金属薄板30远离第一平板部13的一侧；金属片31对应第一平板部13、第二平板部14和折叠部15设置，金属片31位于有效显示部5和金属薄板30之间。
具体的，金属片31的材料为弯折性能佳、弹性恢复性好、平整性好以及耐拉伸的材料，包括不锈钢薄片、非晶材料和热塑性聚氨酯弹性体橡胶（TPU）中的任意一种或多种，金属片31可以为一层结构也可以为多层结构，金属片31为多层结构时，每一层的材料不相同，且金属片31对应第一平板部13和第二平板部14采用的材料与对应折叠部15采用的材料可以不相同，例如，与第一平板部13和第二平板部14对应的金属片31的材料为不锈钢薄片，而与折叠部15对应的金属片31的材料为TPU，此处对金属片31的具体结构不做限制；金属片31的厚度为0.03mm~1mm；金属薄板30为刚性较好的材料，包括铝合金或不锈钢；当然，此处对金属片31和金属薄板30的具体材料不做限制。
具体的，金属片31厚度较薄，可以层压到位于柔性基板9背部的第一背板8上，金属薄板30刚性较好，可以层压到金属片31上，可以实现量产层压金属片31和金属薄板30，大大提高生产效率。当然，金属片31也可以通过粘贴胶与第一背板8连接，金属薄板30也可以通过粘贴胶与金属片31连接，此处不做限制。
具体的，金属薄板30包括靠近弯折部20的第五侧壁32（等同于上述的第一侧壁21），与第五侧壁32相邻设置的第六侧壁33和第七侧壁34，以及与第五侧壁32相对设置的第八侧壁35；第六侧壁33和第七侧壁34与第八侧壁35也相邻设置；沉槽7靠近弯折部20的一侧延伸至第五侧壁32；第六侧壁33、第七侧壁34和第八侧壁35（等同于上述的第二侧壁26、第三侧壁27和第四侧壁28）均为倾斜面，且倾斜角度大于0°且小于90°。
本实施例中，在柔性显示面板2的有效显示部5的背部设置了金属片31和金属薄板30，且金属薄板30上设有沉槽7，相互电连接的电路板3和绑定部6均设置在沉槽7内，一方面，金属薄板30为刚性结构，可以避免有效显示部5正面的按压操作导致有效显示部5内凹变形而影响电路板3和绑定部6之间的线路以及绑定部6与有效显示部5之间的线路连接稳定性，另一方面，电路板3和绑定部6均设置在沉槽7内，可以避免柔性显示模组1的背部在放置时或进行其他制程时直接触压到电路板3和绑定部6，从而减小电路板3和绑定部6之间的线路以及绑定部6上的线路断裂的概率；另外，金属薄板30由刚性材料制得，沉槽7设置在金属薄板30上，易加工成型，金属片31为整片式结构，且具有弯折性能佳、弹性恢复性好、平整性好以及耐拉伸等优点，可以有效的支撑和保护柔性显示面板2的折叠部15，并在折叠部15展开时帮助折叠部15恢复平整，减少折叠部15产生波纹状折痕，增加了柔性显示模组1的使用寿命且提高了柔性显示模组1的显示效果。
如图8所示，本申请实施例还提供了一种柔性显示装置36，包括底壳37和上述实施例所公开的柔性显示模组1，底壳37位于柔性显示模组1的背部，用于承载柔性显示模组1。
具体的，底壳37的结构与柔性显示模组1的背部结构相匹配，即若柔性显示模组1的背部设有凸起结构，则对应的底壳37上设有形状和大小与该凸起结构相匹配的凹槽结构，若柔性显示模组1的背部设有凹槽结构，则对应的底壳37上设有形状和大小与该凹槽结构相匹配的凸起结构。
具体的，面板保护结构4远离柔性显示面板2的一侧还可以设置至少一个螺孔（图中未示出），对应的，底壳37与螺孔对应的位置可以设置通孔，并通过螺丝钉将底壳37与面板保护结构4进一步固定，也就是将底壳37与柔性显示模组1固定。
本实施例中，在柔性显示模组1的背部设置底壳37，底壳37既可以承载和保护柔性显示模组1，也可以使柔性显示装置36美观。
在一实施例中，面板保护结构4的相对的两个侧壁上均设有第一限位结构38；底壳37对应面板保护结构4设有形状和大小与面板保护结构4相匹配的凹槽39，面板保护结构4以及设于沉槽7内的电路板3和绑定部6均位于凹槽39中，且凹槽39的侧壁对应两个侧壁分别设有与第一限位结构38相匹配的第二限位结构40，用以固定柔性显示模组1。
具体的，第一限位结构38与第二限位结构40配合使用可以实现限位功能，第一限位结构38包括凸包或卡槽，当第一限位结构38为凸包时，第二限位结构40为与凸包相匹配的卡槽，当第一限位结构38为卡槽时，第二限位结构40为与卡槽匹配的凸包；当然，第一限位结构38和第二限位结构40不限于列举的这两种结构。
具体的，面板保护结构4的两个侧壁上的第一限位结构38为对称分布的，且每个侧壁上可以有一个或多个第一限位结构38；第一限位结构38的数量和第二限位结构40的数量相同，且一一对应设置。
具体的，第一限位结构38设置在上述实施例中的第二侧壁26和第三侧壁27上，或设置在第六侧壁33或第七侧壁34上。
本实施例中，柔性显示模组1与底壳37整机装配时，通过第一限位结构38和第二限位结构40进行限位固定，操作简单，有利于提高整机装配效率；另外，底壳37上设有与面板保护结构4对应的凹槽39，可以使整机装配后的柔性显示装置36的显示面保持平整，有利于提高柔性显示装置36的显示效果和使用寿命。
在一实施例中，凹槽39的侧壁对应第二侧壁26、第三侧壁27和第四侧壁28也为倾斜面，且凹槽39的侧壁的倾斜方向和倾斜角度与对应的第二侧壁26、第三侧壁27和第四侧壁28的倾斜方向和倾斜角度相同，使得柔性显示模组1与底壳37整机装配时，柔性显示模组1可以通过面板保护结构4的第二侧壁26、第三侧壁27和第四侧壁28滑入底壳37中，操作简单，组装方便，可以节省整机装配的时间，提高生产效率。
在上述实施例中，对各个实施例的描述都各有侧重，某个实施例中没有详述的部分，可以参见其他实施例的相关描述。
