Abstract

本发明涉及一种显示面板及显示装置。显示面板包括面板层及支撑层。面板层包括面板区及位于面板区在第一方向上一侧的弯折区；支撑层位于面板区的背侧，包括支撑主体及位于支撑主体背离面板层的一侧设有支撑结构，支撑结构位于支撑层与弯折区相对的边缘内侧，使得弯折区弯折后通过支撑结构固定于支撑层。上述显示面板中，支撑结构的设置，使得弯折区弯折后通过支撑结构固定于支撑层，相对于直接将弯折区粘结于支撑层背离面板层一侧的实施方式而言，有利于减小弯折区在弯折时的曲率半径，从而有利于减小弯折区所占用的边宽，即减小显示面板在弯折区所对应边缘的边框宽度，有利于缩小该边框与其他边框之间的宽度之差，从而有利于提高用户使用体验。

人们常用的车载显示装置中，相较于LCD面板及刚性OLED面板，柔性OLED面板的应用占比越来越大。一些车载显示装置，在用户使用时，可以进行横屏播放使用(比如图)，也可以进行纵屏播放使用。比如图1所示的一种车载显示装置的显示面板100’，其具有显示区S1’，及位于S1’外围的非显示区S2’(可以理解为边框区)，该非显示区S2’具有一对应将IC芯片绑定到显示面板背侧的显示面板100’背侧的较宽的边框区S20’。具有该显示面板100’的车载显示装置，其在进行如图1中左侧的横屏播放使用模式时，较宽的边框区S20’位于显示区的下边框。而在进行如图1中右侧的纵屏使用模式时，较宽的边框区S20’位于显示区的一侧，给用户带来不交视觉效果。
为此，本申请提供一种显示面板及显示装置。所述显示面板包括面板层及支撑层。所述面板层包括面板区及位于所述面板区在第一方向上一侧的弯折区；所述支撑层位于所述面板区的背侧，所述支撑层包括支撑主体及位于所述支撑主体背离所述面板层的一侧设有支撑结构，所述支撑结构位于所述支撑层与所述弯折区相对的边缘内侧，使得所述弯折区弯折后通过所述支撑结构固定于所述支撑层。上述显示面板中，所述支撑结构的设置，使得所述弯折区弯折后通过所述支撑结构固定于所述支撑层，相对于直接将弯折区粘结于支撑层背离面板层一侧的实施方式而言，有利于减小弯折区在弯折时的曲率半径，从而有利于减小弯折区所占用的边宽，即减小显示面板在该边缘的边框宽度，有利于缩小该弯折区所对应边框与其他边框之间的宽度之差，从而有利于提高用户使用体验。
本申请所说的显示面板，可以为柔性OLED面板。该显示面板可以应用于车载显示装置(比如车载导航显示器件，倒车影像装置等)中，作为车载显示装置的显示面板。当然该显示面板也可应用于手机、平板电脑、电视 机、笔记本电脑、等具有显示功能的产品或部件中，作为手机、平板电脑、电视机、笔记本电脑、等具有显示功能的产品或部件的显示面板。
下面结合附图2至图10对本申请所提供的显示面板及显示装置进行详细描述。
首先，请参照图2所示，并在必要时结合图3和图4所示，本申请提供一种显示面板100。该显示面板具有显示区S1及位于显示区外围的非显示区S2。该非显示区S2也可以理解为边框区。该实施例中，在位于显示区S1第一方向上一侧的为非显示区S20(也可以称为边框区S20)。
可以理解的是，这里第一方向为显示面板100的长度方向。当然，在其它一些实施例中，第一方向也可以为显示面板的宽度方向。本申请对此不做限定。
这里所说的显示面板为柔性有机发光二极管(Organic Electro-luminescence Display，OLED)面板。
该显示面板100包括面板层40及支撑层10。面板层40包括面板区41及位于所述面板区41在第一方向上一侧的弯折区42。支撑层10位于所述面板区41的背侧，所述支撑层10包括支撑主体11及位于所述支撑主体11背离所述面板层40的一侧设有支撑结构12，所述支撑结构12位于所述支撑层10与所述弯折区42相对的边缘内侧，使得所述弯折区42弯折后通过所述支撑结构12固定于所述支撑层10。
可以理解的是，该面板层40的面板区41和弯折区42可以为一体的，比如弯折区42可以为面板层40的面板区41的部分柔性膜层延伸而形成的。当然，在其它一些实施例中，弯折区42也可以是单独设置的柔性结构，并在制备过程中粘贴于面板层40的面板区41之上。
这里所说的面板区41包括具有发光器件的发光层及具有薄膜晶体管的驱动电路层等结构层。
这里所说的支撑层10可以为金属支撑结构层。比如可以采用铜等金属结构，在为显示面板100提供背侧支撑的同时，还可以具有一定的散热作用。
该实施例中，边框区S20即可理解为弯折区42所对应的区域，也即弯折区42在该边框区S20向显示面板100背侧(即支撑层10的背侧)弯折，并绑定于支撑层10的背侧。
该显示面板100中，所述支撑结构12的设置，使得所述弯折区42弯折后通过所述支撑结构12固定于所述支撑层10，相对于直接将弯折区粘结于支撑层背离面板层一侧的实施方式而言，有利于增加弯折区42的在厚度方向上的延伸尺寸，减小弯折区42在弯折时的曲率半径，从而有利于减小弯折区42所占用的边宽，即减小显示面板100在该边缘的边框宽度(即边框区S20在第一方向上的尺寸)，有利于缩小该弯折区42所对应边框与其他边框之间的宽度之差，从而有利于提高用户使用体验。
在一些实施例中，所述支撑结构12包括位于所述显示面板100边缘的过渡支撑面122，在第一方向上，所述过渡支撑面122的至少部分呈外凸的圆滑曲面。
这里的过渡支撑面122可以理解为位于支撑结构12中自对应弯折区42侧边向支撑结构12中部延伸预设宽度的表面，且过渡支撑面122的全部或大部分位于背离显示面板100的一侧。该预设宽度可以根据具体情况进行确定。
可以理解的是，弯折区42弯折后，其表面抵于过渡支撑面122上。在第一方向上，所述过渡支撑面122的至少部分呈外凸的圆滑曲面，能够在对弯折区42进行支撑的同时，还能够很好地保护弯折区42。尤其是相对于过渡支撑面其他非圆滑面而言，能够防止弯折区42在抵于支撑结构12局部受到较大的支撑力而对弯折区42带来不利影响。
在一些实施例中，在第一方向上，所述过渡支撑面的至少部分呈圆滑弧面。
请结合图4所示，所述支撑结构12还包括位于所述固定贴合面121更靠近所述显示面板100边缘的过渡支撑面122，在第一方向上，所述过渡支撑面122的至少部分呈圆滑弧面。
可以理解的是，在一些实施例中，所述过渡支撑面的至少部分可以呈一段弧面。比如圆弧面。
在另一些实施例中，在第一方向上，所述过渡支撑面的至少部分呈多段依序相连并光滑过渡的弧面。各段弧面中有一部分弧面与其他弧面的弯曲程度或者曲率可不同，各段弧面的弯曲程度或曲率也可各不相同。
在一些实施例中，所述支撑结构12包括位于所述过渡支撑面122更靠近所述支撑层10中部的固定贴合面121，所述固定贴合面121背离所述面板层40并呈平直状，所述固定贴合面121与所述过渡支撑面122的连接处光滑过渡。
可以理解的是，IC芯片等器件的可以贴附及固定在该平直状固定贴合面121上，这里将固定贴合面设置呈平直状，方便IC芯片等器件的贴附及固定。
可以理解的是，这里固定贴合面也可以大致呈平直状。或者，在一些实施例中，支撑结构的固定贴合面也可不呈平直状而呈曲率较大的圆润曲面，IC芯片等器件依然可以贴附于其上。
这里固定贴合面121与所述过渡支撑面122的连接处光滑过渡可以更好地对对弯折区42进行支撑及保护。
这里支撑结构12的表面整体呈一异形的圆滑表面。其中，过渡支撑面122的设置，能够更好地保护及支撑弯折区。
需要说明的是，在有些实施例中，所述支撑结构也可不包括固定贴合面，相应地，所述弯折区弯折时经所述过渡支撑面支撑后可以继续向内延伸， 而与支撑主体的表面贴合，IC芯片等器件可以对应贴附于贴合在支撑主体的那部分弯折区上，并且位于弯折区背离支撑主体的表面上。
在一些实施例中，所述支撑结构12与所述支撑主体11一体成型。如此使得整个支撑层10的制备较为简单方便。
当然，在其它一些实施例中，支撑结构与支撑主体也可分开设置，并在后续通过粘结等方式固定于一起。
请继续结合图4所示，在一些实施例中，所述支撑结构12为采用压铸工艺形成的实体结构。
具体的，支撑结构12与支撑主体11在同一压铸工艺中同时形成。
在一些实施例中，所述支撑结构的过渡支撑面边缘可以与支撑主体的边缘或背离所述面板层的表面圆滑过渡。
比如图4所示，过渡支撑面122与支撑主体11的边缘圆滑过渡，二者形成了半圆形表面1210。可以理解的是，在其它一些实施例中，该表面1210也可呈一非半圆形的圆弧面或多段曲率不同的弧面组成的圆滑曲面等。
发明人(们)经过研究发现，在一些实施例中，所述支撑结构12的厚度方向尺寸h1与所述支撑层10在厚度方向尺寸h2之间满足如下关系：
h1≤4h2。
满足该条件下，在能够很好实现边框控制的同时，还有利于控制显示面板100的厚度方向尺寸。
该实施例中，通过具体结构设置支撑结构12的厚度方向尺寸h1的具体尺寸，可以实现边框区S20与非显示区中其他边框区的尺寸相等或大致相等，如此可使得显示面板100在使用过程中，不管是采用横屏播放使用模式还是纵屏播放使用模式，不会因为显示面板中某一边框区的宽度太大给用户带来不好的视角体验，有利于提高用户体验。比如，在一些实施例中，可以 实现图2中的边框区S20的宽度D与其他边框区的宽度D1相等或大致相等，从而很好地提高用户体验。可以理解的是，图2所示D1示意了一个边框区的宽度，实际上除了边框区S20以外的另外两边框区的宽度也相应为D1。
发明人(们)进一步研究发现，通过支撑结构12的设置，可使得边框区S20的宽度D达到6mm以下。在较优的实施方式中，边框区S20的宽度D，能够与其它边框区的宽度(比如D1)一样，达到4mm甚至更小。
此外，该显示面板100还可包括设于面板层40和支撑层10之间的背板层30(即BF层)及散热层20，以及依序层叠于面板层40背离支撑层10一侧的偏光片50、光学胶层61、触控层70、光学胶层62以及盖板层80。该显示面板100还可包括通过粘结胶90贴附于支撑层10背离面板层40一侧的电路板(即PCB板)，以及贴附于弯折区42背离支撑结构12一侧的IC芯片110。芯片110通过连接线与PCB板实现电气连接。
该盖板层80的边缘对应非显示区S2设有遮光区801。该遮光区801可以通过丝印油墨等方式形成。可以理解的是，图4中遮光区801所对应的非显示区即为边框区S20。上述实施方式有利于减小弯折区42在弯折时的曲率半径，从而有利于减小弯折区42所占用的边宽，即减小了宽度d的尺寸，从而减小了遮光区801的宽度D的尺寸，也即减小了显示面板100在边框区S20在第一方向上的尺寸，有利于缩小该弯折区42所对应边框区S20与其他边框之间的宽度之差，从而有利于提高用户使用体验。
可以理解的是上述图3和图4所示实施方式中，支撑结构12为在第二方向上连续延伸的结构。当然，在其它一些实施例中，所述支撑结构也可包括在第二方向上间隔排布的多段支撑部。其中，所述第二方向与所述第一方向及所述显示面板的厚度方向均垂直。
这里所说的第二方向可以理解为显示面板的宽度方向。当然，在其它一些实施例中，第二方向也可以理解为长度方向。本申请对此不做具体限定。
比如，请参照图5，并在必要时结合图6所示，在一些实施例中，本申请提供另一种显示面板200，该显示面板200中，所述支撑结构12包括在第二方向上间隔排布的多段支撑部的，所述多段支撑部在第二方向上的尺寸之和L，与所述支撑层10在第二方向上的尺寸L0之间满足如下关系：
L≥0.9L0。
该条件在节省制造成本的同时，使得支撑结构12能够很好地支撑弯折区。
比如图6所示，支撑结构12包括两段通过缺口1201间隔开的第一支撑部1202和第二支撑部1203。其中，第一支撑部1202在第二方向上的尺寸为L2，第二支撑部1203在第二方向上的尺寸为L1。该两段间隔的第一支撑部1202和第二支撑部1203在第二方向上的尺寸之和为L1+L2。所述支撑层10在第二方向上的尺寸L0，则该尺寸之和L1+L2≥0.9L0。
当然，在其它一些实施例中，支撑结构12在第二方向上还可包括更多段间隔排布的支撑结构，本申请对此不做限定。
可以理解的是，弯折区在第二方向上的尺寸小于支撑结构在第二方向上的尺寸，且一般居中对应于面板区，则对于多段间隔设置的支撑部，该多段支撑部可更多集中于中部区域。
请继续结合图6所示，该支撑结构12背离支撑主体11或者背离面板层40一侧的表面整体呈一外凸曲面。该表面可整体作为过渡支撑面122。在第一方向上，该过渡支撑面122包括依序连接的第一段表面1221、第二段表面1222、第三段表面1223及第四段表面1224。这里依序连接的第一段表面1221、第二段表面1222、第三段表面1223及第四段表面1224均为圆滑的曲面。且第一段表面1221、第二段表面1222、第三段表面1223及第四段表面1224中各相邻的表面的连接处均光滑过渡。
可以看出，这里至少第二段表面1222、第三段表面1223为外凸的弧面， 且曲率不相同。
可以理解的是，在其它一些实施例中，该第一段表面1221、第二段表面1222、第三段表面1223及第四段表面1224中也可部分作为过渡支撑面122，比如第一段表面1221、第二段表面1222及第三段表面1223可作为过渡支撑面122，或第二段表面1222及第三段表面1223作为过渡支撑面122。而第四段表面1224可作为固定贴合面。
可以理解的是，第四段表面1224作为固定贴合面时，其整体可以做的更平直些
该显示面板200的其它结构与上述显示面板100的其它结构类似，可参照上述相关描述。
对于与支撑主体11一体成型的方式，除了可以采用压铸工艺形成，还可以采用其他方式形成。比如板状弯折的方式形成。
请参照图7所示，在另一些实施例中，本申请另提供一种显示面板300，该显示面板300中，所述支撑主体11为板状结构，所述支撑结构12为采用与所述支撑主体11连接的板状结构弯折成型。
该类支撑结构12在第二方向上可以为连续延伸的连续结构，也可以包括更多段间隔排布的支撑部。
该支撑结构12外部形状与上述图3和图4所示的支撑结构的外部形状类似，可参照上述相关描述。
可以理解的是，上述支撑结构12还可设置为其它形状，这里不做具体限定。
该显示面板300的其它结构与上述显示面板100的其它结构类似，可参照上述相关描述。
对于支撑结构与支撑主体分开设置的实施方式，支撑结构12的整体可 以根据需要设置为更多形状及具体结构，且方便支撑结构12的制造。
请参照图8所示，并在必要时结合图9和图10所示，在另一些实施例中，本申请提供一种显示面板400，该显示面板400中，所述支撑结构12为一层板状结构或由多层板状结合层叠而成。
比如，图10所示，该支撑结构12由多层层叠的层结构124、125及126层叠而成。该多层层结构中的层结构124和126可以为粘结胶。125为强度较大的支撑结构层，比如金属层或者气体材料所形成的支撑层。
当然，在其它一些实施例中，该三层层结构也可均为强度较大的支撑结构层。
可以理解的是，在其它一些实施例中，支撑结构12还可以为具有其它多层比如2层、4层等的多层层叠结构。
需要说明的是，该实施例中，支撑结构12背离面板层40的一侧即为固定贴合面121，而无圆滑的过渡支撑面。可以理解的是，在其它一些实施例中，采用多层层叠形成的单独的支撑结构12同样可以根据需要设置过渡支撑面，以更利于弯折区圆滑过渡，对弯折区更好地进行保护及支撑。
进一步的，在一些实施例中，所述支撑结构12由多层板状结构层叠而成的，在所述显示面板100的厚度方向上，相邻两层板状结构中，靠近所述面板层40的板状结构在第一方向上的尺寸大于背离所述面板层40的板状结构在第一方向上的尺寸，其中，所述显示面板的厚度方向与所述第一方向垂直。
请继续结合图10所示，该多层板状结构层124、125、126可以形成一类似楔形的支撑结构。
当然，层叠多层板状结构层叠而成的支撑结构12，其各层结构层的尺寸也可不做上述限定，比如，也可层叠成一矩形或者其它形状的支撑结构。
该显示面板400的其它结构与上述显示面板100的其它结构类似，可 参照上述相关描述。
本申请另提供一种显示装置。该显示装置可包括如上所示的显示面板100或类似的显示面板。该显示装置还包括具有壳体的设备主体。显示面板100或类似的显示面板具体可组装于所述设备主体上
这里所说的显示装置可以是车载导航显示器件，倒车影像装置等车载显示装置，也可以是手机、平板电脑、电视机、笔记本电脑、等具有显示功能的产品或器件。
在本申请中，所述结构实施例与方法实施例在不冲突的情况下，可以互为补充。
在本发明中，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性。术语“多个”、“若干”指两个或两个以上，除非另有明确的限定。
