 本发明的实施方式
以下各实施例的说明是参考附加的图示，用以例示本发明可用以实施的特定实施例。本发明所提到的方向用语，例如[上]、[下]、[前]、[后]、[左]、[右]、[内]、[外]、[侧面]等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本发明，而非用以限制本发明。在图中，结构相似的单元是用以相同标号表示。
首先对现有技术进行简要说明。参见图1，图1为现有技术中的显示面板的结构示意图。图1中的显示面板为液晶显示面板。参见图1，现有技术中的显示面板包括基板10、薄膜晶体管层20、像素层30、封装层40和盖板50。由于基板10的出光面和侧面之间的夹角为90度，薄膜晶体管层20在弯折时所产生的夹角也为90度。这种形状导致薄膜晶体管层20在弯折处的应力很大，容易引起薄膜晶体管层20中的金属线断裂或无机薄膜剥离，使显示面板无法正常工作。
因此，本发明提供了一种显示面板和电子设备，以减小显示面板的弯折区的应力。参见图2和图3，图2为本发明的一个具体实施例中的显示面板的结构示意图，图3为图2中的背光结构的局部放大示意图。所述显示面板包括基板12、薄膜晶体管层22、像素层30、封装层40和盖板50。
所述基板12包括与所述显示面板的出光面平行的第一表面和第二表面。在本实施例中，所述显示面板为液晶面板。所述基板12中含有背光模组。所述基板12的出光面为第一表面在本发明的其他实施例中，所述显示面板也可以是OLED显示面板。由于液晶显示面板的基板中含有背光结构，其厚度通常大于OLED显示面板，受弯折应力的影响更加严重，因此本实施例中以液晶面板为例进行说明。需要强调的是，本发明的技术方案同样可以应用于OLED显示面板或其他类型的显示面板中。
所述薄膜晶体管层22位于所述第一表面上，所述薄膜晶体管层的面积大于所述基板12的面积。所述薄膜晶体管层包括位于所述基板第一表面正上方的显示区控制电路和覆盖所述基板12的侧面和部分第二表面的非显示区控制电路。
所述像素层30位于所述薄膜晶体管层22上。在本实施例中，所述像素层30包括液晶层和覆盖所述液晶层的彩膜层。在其他实施例中，如果所述显示面板为OLED显示面板，则所述像素层30为OLED发光层。
在本发明中，参见图2，所述基板12的第一表面通过至少一个弧形连接面与所述第二表面连接，构成所述基板12的至少一个弧形端。所述薄膜晶体管层紧贴所述至少一个弧形端弯折至所述第二表面。
参见图3，所述弧形连接面包括：第一曲面121和第二曲面122。
所述第一曲面121以所述第一表面的边界为起点，延伸至所述第一表面和所述第二表面的中位线。所述第二曲面122以所述第二表面的边界为起点，延伸至所述第一表面和所述第二表面的中位线。所述第一曲面121和第二曲面122的终点在B点处重合，构成所述弧形连接面。
在本实施例中，重合处的第一曲面的切面和第二曲面的切面重合。优选的，所述弧形连接面在重合处的切面与所述显示面板的出光面垂直。优选的，参见图3，所述第一曲面121和第二曲面122沿着所述第一平面和第二平面的中位线轴对称。
在本发明的其他实施例中，考虑到所述基板12的厚度不同，所述弧形连接面还可以包括侧面。所述侧面的一条边界连接所述第一曲面121的终点，连接处的第一曲面121的切面与所述侧面重合。所述侧面的另一条边界连接所述第二曲面122的终点，连接处的第二曲面122的切面与所述侧面重合。
在本实施例中，所述薄膜晶体管层22与所述基板12直接接触，为了保证所述薄膜晶体管层22与所述第一曲面的水平切面与所述第一表面重合。此时，所述薄膜晶体管层22与所述第一曲面的水平切面（所述第一曲面121在B点处的切面）与所述第一表面重合。
在其他实施例中，所述薄膜晶体管层22与所述基板12之间还包括其他光学薄膜。参见图4和图5，图4为本发明的另一个具体实施例中的显示面板的结构示意图，图5为图4中的背光结构的局部放大示意图。图4中，所述薄膜晶体管层24与所述基板14之间还包括偏光片16，所述薄膜晶体管层24与所述偏光片16直接接触。此时，如果连接所述基板14的第一曲面141和第二曲面142的结构与图3中的结构相同，则薄膜晶体管层24与基板14之间会存在缝隙，无法紧密贴合，导致薄膜晶体管层24的抗压性差，容易在缝隙处断裂，导致显示面板无法正常工作。
因此，在这种情况下，为了保证所述薄膜晶体管层24与所述基板14的侧面无缝贴合，所述第一曲面141的水平切面（在B点处的切面）高于所述第一表面，并与所述偏光片16的出光面相重合。优选的，参见图4，所述第一曲面141和第二曲面142沿着所述第一平面和第二平面的中位线非对称设置。
参见图4，这样设置，可以确保所述薄膜晶体管层24与所述基板14的侧面无缝贴合，避免弯折处出现缝隙而降低所述薄膜晶体管层24的抗压性。
相应的，本发明还提供了一种电子设备，其包括如前所述的显示面板。
本发明将液晶显示面板的背光结构的至少一个边缘处设置为向外凸起的圆弧形，背光结构的侧面和出光面之间通过平滑的圆弧拐角连接，使得位于所述背光结构上的薄膜晶体管层沿着所述圆弧形拐角弯折到背光结构的出光面背面。圆弧形侧弯折有效的减小了弯折处的应力，避免了由于拐角处弯折强度过大而导致的显示失效问题。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
