随着科技的发展，显示产品得到了越来越广泛的应用，其中，LCD (Liquid Crystal Display，液晶显示器)和OLED显示面板应用极为广泛。目前，在LCD中以玻璃基底为基材提供支撑性；而OLED常以PI膜作为基材，但PI基材不具备支撑性，因此常通过在OLED显示面板表面增设CG(Glass Cover，玻璃盖板)以增强支撑性。但是由于在OLED显示面板中设置了CG盖板，导致了OLED显示面板较厚、生产成本较高等问题。
为了解决上述问题，目前市场上的OLED产品，例如NB(Note Book，笔记本电脑)产品通常采用刚性基底+柔性封装的设计方案，为OLED产品提供支撑性。但是由于刚性基底本身为刚性材料不可弯折，从而无法对OLED产品的单侧边，例如下边框进行弯折，而只能进行如图1所示的FPC(Flexible Printed Circuit，柔性电路板)bending(弯折)方案或者COF(Chip On Film，覆晶薄膜)bending方案等，导致OLED产品无法实现窄边框。参考图1所示，在glass衬底20上依次层叠设置OLED显示面板21和TFE(Thin Film Encapsulation，薄膜封装)层22，并在glass衬底11上设置驱动芯片23，同时还在glass衬底20远离OLED显示面板21的一侧依次层叠设置SCF(散热层)层24、spacer(隔垫物)层25和FPC(Flexible Printed Circuit，柔性电路板)26，此时仅能够通过对FPC26进行弯折，以实现OLED显示面板21的弯折。
基于上述，本申请实施例提供了一种显示面板，参考图2-图3、图12-图13所示，该显示面板包括：器件设置区D1、弯折区D2和绑定区D3，弯折区D2位于器件设置区D1和绑定区D3之间。
参考图2-图3、图12-图13所示，显示面板还包括衬底1和设置在衬底1上的显示基板2，显示基板2位于器件设置区D1；衬底1位于器件设置区D1、弯折区D2和绑定区D3，衬底1至少包括刚性衬底11，衬底1位于弯折区D2的部分被配置为能够沿弯折轴弯折。
上述器件设置区是指用于设置显示器件的区域，上述绑定区是指用于绑定驱动芯片、电路板等的区域。通过在显示面板上设置显示器件、驱动芯片、电路板等之后，形成显示装置。
上述弯折区是指能够沿特定方向(例如图2所示的OA方向)进行弯折的区域。
上述衬底至少包括刚性衬底是指：上述衬底仅包括刚性衬底；或者， 上述衬底除包括刚性衬底外，还包括其它材质的衬底，例如柔性衬底。
这里对于上述刚性衬底的材料、厚度等均不做具体限定。示例的，上述刚性衬底的材料可以为玻璃等。示例的，上述刚性衬底沿垂直于显示基板方向的厚度范围可以包括0.3-0.6mm，具体的，刚性衬底沿垂直于显示基板方向的厚度可以为0.3mm、0.4mm、0.5mm或者0.6mm等等。
上述显示基板可以是柔性显示基板，例如OLED显示基板；也可以是刚性显示基板，例如LCD，这里不做限定。本申请提供的实施例均以上述显示基板为OLED显示基板为例进行说明。
需要说明的是，上述弯折轴并不是显示面板中存在的实际结构，只是为了说明显示面板的弯折过程提出的概念。
这里对于上述显示面板的弯折方向也不做限定。示例的，其弯折方向可以为如图2和图3中所示的OA方向，或者，可以是AO方向。其具体弯折方向可以根据实际情况确定。本申请提供的实施例均以上述显示面板沿OA方向弯折为例进行说明。
另外，参考图2-图3、图12-图13所示，显示面板还包括设置在显示基板2远离刚性衬底11一侧的封装层3。这里对于封装层的结构不做具体限定。示例的，封装层可以仅为一层，例如无机层；或者，封装层可以为TFE封装，具体包括第一无机封装层、有机封装层和第二无机封装层，具体以实际应用为准。
本申请实施例提供的显示面板包括器件设置区、弯折区和绑定区，弯折区位于器件设置区和绑定区之间，显示面板还包括衬底和设置在衬底上的显示基板，显示基板位于器件设置区，衬底位于器件设置区、弯折区和绑定区，衬底至少包括刚性衬底，衬底位于弯折区的部分被配置为能够沿弯折轴弯折。从而在通过刚性衬底确保显示面板的支撑性的同时，衬底的弯折区还实现了显示面板的弯折效果。这样既可以保持显示面板的刚性，又能够使得显示面板的单侧边框，例如下边框易于弯折，使得显示面板实现窄边框。
可选的，参考图2和图3所示，衬底1包括刚性衬底11、以及设置在刚性衬底11和显示基板2之间的柔性衬底12；刚性衬底11位于器件设置区D1；柔性衬底12位于器件设置区D1、弯折区D2和绑定区D3，柔性 衬底12位于弯折区D2的部分被配置为能够沿弯折轴弯折。
参考图4和图6所示，显示面板还包括设置在柔性衬底12靠近显示基板(图中示出的是显示基板的显示区AA)一侧的多个驱动单元4，多个驱动单元4均匀分布在绑定区D3。从而通过在显示面板的显示区和非显示区均采用刚性衬底和柔性衬底作为衬底，很好的实现了显示面板的支撑性；同时，由于弯折区采用柔性衬底，能够实现显示面板的弯折，从而实现窄边框。
这里对于上述柔性衬底的材料、厚度等均不做具体限定。示例的，上述柔性衬底的材料可以为PI等。示例的，上述柔性衬底沿垂直于显示基板方向的厚度范围可以包括20-50μm，具体的，柔性衬底沿垂直于显示基板方向的厚度可以为20μm、30μm、40μm或者50μm等等。
这里对于上述驱动单元的结构不做具体限定。示例的，上述驱动单元可以为驱动芯片等。
这里对于上述多个驱动单元中，相邻驱动单元之间的间距不做限定，具体以绑定区的面积、驱动单元的数量等确定。
需要说明的是，可以是首先依次形成刚性衬底和柔性衬底，再在柔性衬底上形成显示基板，此时刚性衬底和柔性衬底可以均设置在器件设置区、弯折区和绑定区。再在EAC工段(显示面板的切割、减薄处理等工段)将弯折区和绑定区的刚性衬底均去除。
可选的，参考图4、图6-图7所示，柔性衬底12位于弯折区D2的部分沿平行于显示基板的长度d1，与柔性衬底12位于器件设置区D1的部分沿平行于显示基板的长度d2和柔性衬底12位于绑定区D3的部分沿平行于显示基板的长度d3二者中的至少一个不同。
当然，参考图6-图7所示，还可以是柔性衬底12位于弯折区D2的部分沿平行于显示基板的长度d1，与柔性衬底12位于器件设置区D1的部分沿平行于显示基板的长度d2和柔性衬底12位于绑定区D3的部分沿平行于显示基板的长度d3二者中的至少一个相同。在d1与d2和d3二者中的至少一个相同的情况下，可以是d1与d2相同；或者，d1与d3相同；或者，d1与d2和d3均相同。图4以d1与d2和d3均相同为例进行绘示，此时便于制作柔性衬底，简单易实现。但是，将该结构的显示面板进行仿 真后发现，如图5所示，虚线框中的弯折区的应力值大概对应的是1.711e+03，该应力值较大，应力集中在弯折区，易造成弯折区裂纹等问题。
在d1与d2和d3二者中的至少一个不同的情形下，可以是d1与d2不同；或者，d1与d3不同；或者，d1与d2和d3均不同。图6和图7均以d1与d2和d3均不同、且d2和d3相同为例进行绘示，此时将图7所示结构的显示面板进行仿真后发现，如图8所示，虚线框中的弯折区的应力值大概对应的是5.500e+01，该应力值明显较小，尤其小于图5中虚线框中的应力值，因此可以有效减小弯折裂纹等问题。
需要说明的是，上述任何一种情况下对于d2和d3的关系不做具体限定，d2和d3可以相同也可以不同，具体以实际应用为准。
可选的，参考图6和图7所示，柔性衬底12位于弯折区D2的部分沿平行于显示基板的长度d1，分别小于柔性衬底12位于器件设置区D1的部分沿平行于显示基板的长度d2和柔性衬底12位于绑定区D3的部分沿平行于显示基板的长度d3。此时可以将弯折区的应力降到安全值以内，减小甚至避免弯折区裂纹等问题的发生。
这里对于上述d2和d3的关系不做具体限定。示例的，d2和d3可以相同；或者，d2和d3可以不同。图6以d2和d3相同为例进行绘示。
可选的，参考图6，柔性衬底12位于器件设置区D1的部分靠近弯折区D2的一侧、以及柔性衬底12位于绑定区D3的部分靠近弯折区D2的一侧均设置有至少一个切角8。从而可以在制作弯折区的柔性衬底时，使得弯折区的柔性衬底沿平行于显示面板方向的长度限定在切角边缘处，实现弯折区的柔性衬底沿平行于显示面板方向的长度最小。也即显示面板边缘做斜向切割，从而压缩了弯折区柔性衬底的总长度。
这里对于上述切角的数量不做具体限定。示例的，上述切角可以为一个；或者，上述切角可以为多个。图6以柔性衬底12位于器件设置区D1的部分靠近弯折区D2的一侧的切角8、以及柔性衬底12位于绑定区D3的部分靠近弯折区D2的一侧的切角8均为两个为例进行绘示。
可选的，参考图6所示，柔性衬底12位于器件设置区D1的部分在衬底上的正投影的外轮廓形状、以及柔性衬底12位于绑定区D3的部分在衬底上的正投影的外轮廓形状均为带有两个切角8的矩形。
可选的，参考图4和图6所示，柔性衬底12位于弯折区D2的部分和柔性衬底12位于绑定区D3的部分均为整体结构。此时便于制作柔性衬底，简单易实现。
可选的，参考图7所示，柔性衬底12位于弯折区D2的部分和柔性衬底12位于绑定区D3的部分均包括多个断开的柔性衬底部，相邻柔性衬底部之间具有贯通的凹槽；各驱动单元4设置在各柔性衬底部12上。从而能够有效减小甚至避免柔性衬底在弯折区发生撕裂、断裂等问题。
这里对于上述凹槽的形成工艺不做具体限定。示例的，可以采用激光工艺将弯折区、绑定区的柔性衬底等去除。
需要说明的是，还可以采用激光工艺将器件设置区靠近弯折区一侧的少量柔性衬底去除，进一步防止弯折区发生撕裂、断裂等。
可选的，参考图9-图11所示，凹槽的外轮廓在衬底上的正投影包括第一线段X1、第二线段X2和第三线段X3，第一线段X1靠近器件设置区D1设置，第一线段X1的一端与第二线段X2相连、且另一端与第三线段X3相连。从而使得相邻柔性衬底部之间断开，即将柔性衬底在弯折区和绑定区的部分沿平行于显示面板方向的长度进一步缩小，进一步减小甚至避免柔性衬底在弯折区发生撕裂、断裂等问题。
这里对于上述第二线段与第一线段的一端相连、以及第三线段与第一线段的另一端相连的具体方式不做限定。示例的，第二线段与第一线段的一端可以直接相连或者间接相连，第三线段与第一线段的另一端也可以直接相连或者间接相连。
这里对于上述第一线段、第二线段和第三线段的形状均不做具体限定。示例的，上述第一线段、第二线段和第三线段可以均为图9-图11所示的直线。
可选的，参考图9所示，第一线段X1的一端与第二线段X2直接相连、且另一端与第三线段X3直接相连。从而便于制作各线段，简单易实现。
可选的，参考图10-图11所示，凹槽的外轮廓在衬底上的正投影还包括第四线段X5和第五线段X6；第一线段X1的一端通过第四线段X5与第二线段X2相连、且另一端通过第五线段X6与第三线段X3相连。从而 可以避免第一线段与第二线段直接通过直角相连、以及第一线段与第三线段直接通过直角相连，能够进一步减小避免柔性衬底在弯折区发生撕裂、断裂等问题。
这里对于上述第四线段和第五线段的形状均不做具体限定。示例的，第四线段和第五线段的形状可以相同，当然也可以不同。
可选的，参考图10-图11所示，第四线段和第五线段的形状均包括直线、弧线。
可选的，参考图2和图3所示，显示面板还包括层叠设置在刚性衬底11远离显示基板2一侧的散热层5和隔垫物6，散热层5和隔垫物6均位于器件设置区D1。
参考图2和图3所示，显示面板还包括设置在柔性衬底12远离显示基板2一侧的支撑层7，支撑层7位于绑定区D2、且驱动单元4在柔性衬底12上的正投影E1位于支撑层7在柔性衬底12上的正投影E2以内；支撑层7被配置为在柔性衬底12位于弯折区D2的部分沿弯折轴弯折后，与隔垫物6接触。从而可以通过散热层对显示面板进行很好的散热，并通过支撑层可以保证驱动单元等在bonding时的强度，确保绑定效果。
这里对于上述散热层的材料不做具体限定。示例的，上述散热层的材料可以为铜箔和泡棉等。
这里对于上述隔垫物的材料不做具体限定。示例的，上述隔垫物的材料可以为铂(Pt)。
这里对于上述支撑层的材料不做具体限定。示例的，上述支撑层的材料可以为模量高、强度高的材料，例如PI、PP(Polypropylene，聚丙烯)等。
可选的，参考图12和图13所示，衬底包括刚性衬底11，刚性衬底11位于器件设置区D1、弯折区D2和绑定区D3；刚性衬底11位于弯折区D2的部分被配置为能够沿弯折轴弯折。从而可以利用UTG技术提供可弯折的刚性衬底，仅通过弯折刚性衬底就实现显示面板的窄边框，同时还提升了bending区的强度。
这里对于上述刚性衬底的材料、厚度等均不做具体限定。示例的，上述刚性衬底的材料可以包括玻璃和特殊材料。示例的，上述刚性衬底沿垂 直于显示基板方向的厚度范围可以包括0.03-0.07mm，以使得该超薄刚性衬底能够弯折。
需要说明的是，可以直接在刚性衬底上制作显示基板，该设计在EAC工段不需要再进行基材剥离、处理等工序，简单易实现。
另外，由于超薄刚性衬底的可弯折特性，可以实现半径较小的弯折，例如图12中R的范围可以包括0.5-1.5mm，具体的，弯折区的半径可以为0.5mm、0.7mm、0.8mm、1.0mm或者1.5mm等等，从而使得显示产品可以应用于车载等领域。
可选的，参考图12所示，刚性衬底11沿垂直于显示基板2方向的厚度均一。从而可以便于制作刚性衬底，简单易实现。
可选的，刚性衬底沿垂直于显示基板方向的厚度范围包括0.03-0.07mm。
这里对于上述刚性衬底沿垂直于显示基板方向的厚度不做具体限定。示例的，刚性衬底沿垂直于显示基板方向的厚度可以为0.03mm、0.04mm、0.05mm、0.06mm或者0.03mm等等。
可选的，参考图13所示，刚性衬底11位于弯折区D2的部分沿垂直于显示基板2方向的厚度，分别小于刚性衬底11位于器件设置区D1的部分沿垂直于显示基板2方向的厚度和刚性衬底11位于绑定区D3的部分沿垂直于显示基板2方向的厚度。从而可以仅通过对刚性衬底位于弯折区的部分进行处理，使得刚性衬底位于弯折区的部分能够弯折，以实现显示面板的窄边框。
这里对于上述刚性衬底的材料不做具体限定。示例的，上述刚性衬底的材料可以包括玻璃。
这里对于上述刚性衬底在器件设置区、弯折区和绑定区的厚度范围不做具体限定。示例的，上述刚性衬底在器件设置区的部分和绑定区的部分的厚度可以相同也可以不同，例如：上述刚性衬底在器件设置区的部分和绑定区的部分沿垂直于显示基板方向的厚度范围可以均包括0.3-0.6mm，具体的，刚性衬底在器件设置区的部分沿垂直于显示基板方向的厚度可以为0.3mm、0.4mm、0.5mm或者0.6mm等等；刚性衬底在绑定区的部分沿垂直于显示基板方向的厚度可以为0.3mm、0.4mm、0.5mm或者0.6mm等 等。示例的，上述刚性衬底在弯折区的部分沿垂直于显示基板方向的厚度范围可以包括0.03-0.07mm，具体的，刚性衬底在弯折区的部分沿垂直于显示基板方向的厚度可以为0.03mm、0.04mm、0.05mm、0.06mm或者0.03mm等等，以使得该超薄刚性衬底能够弯折。
这里对于上述刚性衬底位于弯折区的部分的制作工艺不做具体限定。示例的，可以通过半蚀刻工艺实现刚性衬底位于弯折区的部分的减薄，以刚性衬底为玻璃衬底为例，该具体的蚀刻减薄工艺流程可以为：1、在玻璃衬底上覆防酸膜；2、对弯折区进行蚀刻减薄，例如对弯折区使用混合酸液进行处理，具体的，可以用氢氟酸为主的混合酸液进行化学减薄，反应式为HF+SiO2→H2SiF6+H2O；3、褪膜；4、抛光。
需要说明的是，可以直接在刚性衬底上制作显示基板，该设计在EAC工段不需要再进行基材剥离、处理等工序，简单易实现。
可选的，参考图13所示，刚性衬底11位于器件设置区D1的部分沿垂直于显示基板2方向的厚度和刚性衬底11位于绑定区D3的部分沿垂直于显示基板2方向的厚度相等；刚性衬底11位于弯折区D2的部分远离显示基板2的一侧呈拱形设置。从而便于制作刚性衬底，简单易实现。
可选的，参考图12和图13所示，显示面板还包括层叠设置在刚性衬底11远离显示基板2一侧的散热层5和隔垫物6，散热层5和隔垫物6均位于器件设置区D1；刚性衬底11位于绑定区D3的部分被配置为在刚性衬底11位于弯折区D2的部分沿弯折轴弯折后，与隔垫物6接触。从而可以通过散热层对显示面板进行很好的散热，并通过刚性衬底保证bonding时的强度，确保绑定效果。
这里对于上述散热层的材料不做具体限定。示例的，上述散热层的材料可以为铜箔和泡棉等。
这里对于上述隔垫物的材料不做具体限定。示例的，上述隔垫物的材料可以为铂(Pt)。
需要说明的是，参考图12和图13所示，驱动单元4设置在刚性衬底11靠近显示基板2的一侧、且位于绑定区D3。
