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。
如图 1 ( d) 和图 2所示， 作为本发明的一个方面， 提供一种显 示面板， 该显示面板包括相对设置的第一基板 10和第二基板 20， 第 二基板 20 的外表面包括显示区 100和环绕该显示区 100的边框区 200,其中，所述显示面板还包括设置在第二基板 20的外表面上的导 光件， 该导光件包括第一导光件 41， 该第一导光件 41设置在显示区 100的边缘以将从显示区 100边缘射出的光线 L1传导至边框区 200 的至少一部分的上方。其中， 显示区 100为矩形， 边框区 200为矩形 框。
应当理解的是， "第一导光件 41设置在显示区 100的边缘 "可 以理解为，第一导光件 41设置在显示区 100与边框区 200的交界处， 第一导光件 41可以完全位于显示区 100内， 也可以一部分位于显示 区 100内， 另一部分位于边框区 200内。
如图 4所示，从显示区 100边缘射出的光线 LI ( BP ,显示区 100 边缘下方的背光源发出的光线） 传导至第一导光件 41， 该第一导光 件 41对该光线 L1进行折射， 从而使所述光线可以被传导至边框区 的至少一部分（图 4中所示的是边框区的连接部 220) 的上方， 成为 出射光线 L2。 观看者观看图像时， 可以看到边框区 200的至少一部 分上方的光线形成的图像。
当第一导光件 41传导的光线覆盖边框区 200的一部分时， 可以 实现窄边框显示。 当第一导光件 41传导的光线完全覆盖边框区 200 时， 可以实现无边框显示。
在现有的显示面板的第二基板的显示区上设置第一导光件 41即 可得到本发明所提供的显示面板。 当将显示面板用于终端设备中时， 无需省去连接显示面板和背光源的前框，从而不会降低显示面板与背 光源之间的连接强度。
在本发明中， 对第一导光件 41的具体形式并没有特殊的要求， 只要可以将从显示区 100边缘下方射出的光线 L1折射至边框区 200 上方， 以覆盖边框区 200的至少一部分即可。
为了便于设置并降低所述显示面板的总体成本，优选地，如图 2 中所示， 第一导光件 41可以为柱状件， SP， 第一导光件 41形成为柱 透镜。如图 4所示， 第一导光件 41可以包括安装面 41a、折射面 41b 和连接安装面 41a和折射面 41b的连接面 41c， 安装面 41a与第二基 板 20的外表面贴合， 安装面 41a和折射面 41b位于连接面 41c的同 一侧，且折射面 41b上各点与连接面 41c之间的距离从上至下（此处 所述的 "上、 下"是指图 4中的 "上、 下"方向； 换言之， "从上之 下"是指 "从折射面 41b上远离安装面 41a的一侧至折射面 41b上靠 近安装面 41a的一侧"）逐渐增加， 使得从显示区 100边缘射出的光 线经第一导光件 41折射后从折射面 41b向边框区 200的上方射出。
将第一导光件 41设置为包括安装面 41a、 折射面 41b和连接面 41c的优点在于， 进入第一导光件 41 的光线基本上都朝同一方向折 射，从而可以更好地实现窄边框甚至无边框的显示效果。如图 4中所 示， 连接面 41c可以在与第二基板 20的上表面垂直的同时与显示面 板的侧面对齐。
并且， 对第一导光件 41的横截面形状也没有特殊要求。 第一导 光件 41可以为四分之一圆柱，也可以为棱柱，只要可以将显示区 100 边缘下方发出的光线折射至边框区 200上方即可。
在本发明所提供的实施方式中， 第一导光件 41的横截面为四分 之一圆形。 此外， 第一导光件 41的横截面可以为直角梯形， 容易理 解的是， 在这种情况中， 第一导光件 41的安装面 41a大于第一导光 件 41的顶面。 或者第一导光件 41的横截面还可以为三角形。
如图 2中所示，边框区 200包括功能部 210和连接部 220，功能 部 210位于边框区 200相对的两侧 （图 2中的左右两侧） ， 连接部 220位于边框区 200的其余两侧 （图 2中的上下两侧） ， 且连接在所 述相对的两侧处的功能部 210之间 （即， 功能部 210和连接部 220 围成边框区 200) ， 第一导光件 41的延伸方向平行于连接部 220的 延伸方向。
在本发明中， 可以只设置一个第一导光件 41， 该第一导光件 41 可以将光线折射至与该第一导光件 41相邻的连接部 220的上方。 优 选地， 可以设置两个第一导光件 41， 这两个第一导光件 41的折射面 41b相对设置， 并且这两个第一导光件 41被设置为分别与相对的连 接部 220相邻。 这两个第一导光件 41可以分别将光线传导至两侧的 连接部 220的上方。
当将本发明所提供的显示面板设置在终端设备中时， 将安装终 端设备的功能性部件（例如， 前置摄像头、 听筒、 话筒） 的安装孔设 置在功能部 210中。 并且， 各种电路板、 连接线等（例如， 显示面板 的驱动电路）也设置在功能部 210的下方。在这种实施方式中， 只需 利用第一导光件 41将光线引导至连接部 220的上方即可。 将第一导 光件 41的延伸方向设置为平行于连接部 220的延伸方向的优点在于， 可以简化第一导光件 41的设置方式。 优选地， 两侧的连接部 220均 对应有沿连接部 220的长度方向延伸的第一导光件 41。
此外， 还可以将终端设备的功能性部件的安装孔设置在所述显 示面板的侧面或显示面板上其他位置，此时还可以设置与所述相对的 两侧处的功能部 210相对应的两个第一导光件 41， 从而可以实现无 边框显示。
应当理解的是，对应于连接部 220的两个第一导光件 41以及对 应于功能部 210的两个第一导光件 41被设置为首尾相接以环绕显示 区 100的边缘。
应当理解的是， 第一导光件 41将从显示区 100边缘射出的光线 传递至边框区 200的上方之后，应当仍然能确保图像的连贯性。为了 使所述显示面板显示的图像更加连贯，以使观看者获得理想的视觉效 果， 优选地， 所述导光件还可以包括设置在第二基板 20的外表面上 的第二导光件 42， 如图 2和图 3所示， 第二导光件 42位于相对设置 的第一导光件 41之间，第二导光件 42对图像的放大倍数与第一导光 件 41对图像的放大倍数相同。
图 2中所示的是只设置有对应于连接部 220的第一导光件 41时， 显示面板的俯视图， 在这种实施方式中， 第二导光件 42互相平行设 置。 图 3中所示的是设置有对应于连接部 220的第一导光件 41和对 应于功能部 210的第一导光件 41时， 显示面板的俯视图。 在这种实 施方式中， 设置有平行于连接部 220的第二导光件 42和平行于功能 部 210的第二导光件 42。
在两侧的第一导光件 41之间设置第二导光件 42之后， 可以对 整个显示区 100内显示的图像的各个部分进行同等程度的放大，从而 使观看者看到的图像更加连贯一致，并获得理想的视觉效果。应当理 解的是，第一导光件 41的底面和第二导光件 42的底面覆盖整个显示 区 100。 容易理解的是， 第二导光件 42也为柱状件。
在本发明中，第二导光件 42的形状可以与将两个第一导光件 41 的连接面互相拼接在一起所得到的形状相同。 例如， 当第一导光件 41为四分之一圆柱时， 第二导光件 42可以为二分一圆柱， 当第一导 光件 41的横截面为直角梯形时，第二导光件 42的横截面可以为等腰 梯形。
为了提高利用本发明所提供的显示面板的终端设备的续航能 力， 优选地， 所述显示面板还可以包括太阳能电池 30， 可以将该太 阳能电池 30设置在第二基板 20的外表面上，从而可以通过太阳能电 池 30的采光面采集的太阳能进行发电， 并为包括所述显示面板的终 端设备供电。可以将太阳能电池 30设置在第二导光件 42的内侧（即， 图 5中的下方） ， 一方面， 太阳能电池 30不会遮挡从显示区 100的 边缘射出的光线， 另一方面， 第二导光件 42可以将显示面板外部的 太阳光线 L3聚集在太阳能电池 30的采光面上， SP， 从显示面板外 部入射的太阳光线 L3经第二导光件 42折射后成为相对集中的入射 光线 L4，从而提高太阳能电池 30采集的太阳能的总量（如图 5所示）。
应当理解的是， 在本发明中， "内"指的是， 朝向显示面板内 部的方向， "外"是指朝向显示面板外部的方向。 太阳能电池 30利 用自身的采光面采集到的太阳能进行发电，从而可以为显示面板的驱 动电路供电，或者可以为包括该显示面板的终端设备的电源充电，进 而可以提高包括本发明所提供的显示面板的终端设备的续航能力。
容易理解的是， 在设置有太阳能电池 30的实施方式中， 第二基 板 20的外表面上还应设置有相应的电路结构， 从而可以将太阳能电 池 30产生的电能导出， 以向所述终端设备供电。
本发明对显示面板的具体类型也没有特殊的要求， 显示面板可 以是液晶显示面板，也可以是有机电致发光显示面板，还可以是电致 变色显示面板等。 通常， 如图 1 ( d) 所示， 所述显示面板可以包括 相对设置的第一基板 10和第二基板 20， 太阳能电池 30设置在所述 第二基板 20的外表面上。
当然， 太阳能电 30还可以设置在第一基板 10上， 或者在第一 基板 10以及第二基板 20上同时设置太阳能电池 30， 只要可以通过 采光面采集太阳能以进行发电即可。
当所述显示面板为液晶显示面板时，第一基板 10和第二基板 20 之间填充有液晶材料。第二基板 20的内侧设置有黑矩阵 21和彩膜层 22， 为了使显示面板具有较大的开口率， 优选地， 可以将太阳能电池 30设置在第二基板 20上与黑矩阵 21相对应的位置。
当所述显示面板为有机电致发光显示面板时， 第一基板 10上间 隔设置有有机电致发光二极管， 可以将太阳能电池 30设置在第二基 板 20上与相邻两个有机电致发光二极管之间的间隙相对应的位置。
可以将所述导光件直接设置在太阳能电池 30的外表面上， 或者 为了确保所述导光件牢固地固定在所述显示面板上，可以在第二基板 20的外表面上设置平坦化层 50， 该平坦化层 50覆盖太阳能电池 30 和第二基板 20的外表面， 且平坦化层 50的外表面 （平坦化层 50与 第二基板 20的外表面相贴合的表面为平坦化层 50的内表面，与该内 表面相对的表面为平坦化层 50的外表面） 为平面。 通过将所述导光 件设置在平坦化层 50的外表面上， 可以使所述导光件更加牢固地固 定在显示面板中。 可以利用相同的材料来制造平坦化层 50、 所述第 一导光件和所述第二导光件，从而可以提高所述第一导光件和所述第 二导光件与平坦化层 50之间的结合强度， 防止所述第一导光件和所 述第二导光件脱落。
在所述导光件包括第二导光件 42的实施方式中， 由于平坦化层 50的外表面为平面， 因此可以使第一导光件 41和第二导光件 42更 加均匀一致，对显示面板显示的图像的放大效果也均匀一致，从而使 观看者获得更好的视觉效果。
在本发明中，对形成第一导光件 41、第二导光件 42和平坦化层 50的具体材料并没有特殊的限定。平坦化层 50只要是透明的且可以 固定在第二基板 20的外表面上即可， 同样地，第一导光件 41和第二 导光件 42只要是透明的且可以固定在平坦化层 50的外表面上即可。
例如，可以利用热固性树脂材料形成平坦化层 50和 /或第一导光 件 41和第二导光件 42，或者，可以利用光固化材料形成平坦化层 50 和 /或第一导光件 41和第二导光件 42。
作为本发明的另一个方面， 提供一种终端设备， 所述终端设备 包括显示面板，其中，所述显示面板为本发明所提供的上述显示面板。
如上文所述， 所述显示面板的出光面上设置有第一导光件， 从 而可以将显示面板的显示区的光线传导至边框区的上方，从而可以实 现窄边框显示甚至无边框显示。
在包括太阳能电池的实施方式中， 可以将太阳能电池与显示面 板的驱动装置（例如， 栅极驱动器或源极驱动器）相连， 从而可以提 供驱动显示面板所需的电量。
或者， 可以将太阳能电池直接与终端设备的电源相连， 利用所 述太阳能电池为所述电源充电。将太阳能电池与电源相连可以简化电 路结构， 易于实现。例如， 直接将太阳能电池的正极与所述电源的正 极相连， 并直接将太阳能电池的负极与所述电源的负极相连。
作为本发明的再一个方面， 还提供一种显示面板的制造方法， 如图 1 ( a) 至图 1 ( d) 和图 2所示， 所述显示面板包括第一基板 10 和第二基板 20， 第二基板的外表面包括显示区 100和环绕该显示区 100的边框区 200 (图 2和图 3 ) ， 所述制造方法包括：
设置导光件 （如图 （Id) 所示） ， 使得该导光件包括第一导光 件 41， 该第一导光件 41位于显示区 100的边缘， 以将从显示区 100 边缘射出的光线传导至边框区 200的至少一部分的上方。
应当理解的是， 所述制造方法还包括在所述设置导光件的步骤 之前进行的将第一基板 10和第二基板 20对盒的步骤 （如图 1 ( a) 所示） 。
可以通过多种方式设置所述导光件， 例如， 可以通过构图工艺 形成所述导光件， 或者， 可以通过卷对卷 （roll to roll) 转印工艺形 成所述导光件。 或者， 可以通过机加工的方式预先制成所述导光件， 随后将所述导光件粘合在显示面板的第二基板 20的外表面上。
如上文中所述， 为了便于加工制造并降低所述显示面板的总体 成本， 优选地， 第一导光件 41可以为柱状件。 并且， 在本发明中对 第一导光件 41的横截面形状也没有特殊限制， 只要可以将从显示区 100边缘射出的光线传导至边框区 200的至少一部分的上方即可。如 图 4所示， 第一导光件 41可以包括安装面 41a、 折射面 41b和连接 安装面 41a和折射面 41b的连接面 41c， 安装面 41a与第二基板 20 的外表面贴合， 安装面 41a和折射面 41b位于连接面 41c的同一侧， 且折射面 41b上各点与连接面 41c之间的距离从上至下（此处所述的 "上、 下"是指图 4中的 "上、 下"方向； 换言之， "从上之下"是 指"从折射面 41b上远离安装面 41a的一侧至折射面 41b上靠近安装 面 41a的一侧"）逐渐增加， 使得从显示区 100边缘射出的光线经第 一导光件 41折射后从折射面 41b向边框区 200的上方射出。
将第一导光件 41设置为包括安装面 41a、 折射面 41b和连接面 41c的优点在于， 进入第一导光件 41 的光线基本上都朝同一方向折 射，从而可以更好地实现窄边框甚至无边框的显示效果。如图 4中所 示， 连接面 41c可以与显示面板的侧面对齐。
如上文中所述， 如图 2中所示， 边框区 200包括功能部 210和 连接部 220， 功能部 210位于边框区 200相对的两侧（图 2中的左右 两侧），连接部 220位于边框区 200的其余两侧（图 2中的上下两侧）， 且连接在所述相对的两侧处的功能部 210之间（即，功能部 210和连 接部 220围成边框区 200) ， 可以与所述相对的两侧处的连接部 220 均对应并沿连接部 220的长度方向设置第一导光件 41。
或者， 可以与所述其余两侧处的功能部 210均对应并沿功能部 210的长度方向设置第一导光件 41。
如图 3中所示， 可以同时设置平行于连接部 220的第一导光件 41和平行于功能部 210的第一导光件 41。
上文中已经对功能部 210和连接部 220进行了具体描述， 这里 不再赘述。
为了使所述显示面板显示的图像更加连贯， 以使观看者获得理 想的视觉效果， 优选地， 所述导光件还可以包括第二导光件 42， 将 该第二导光件 42设置在相对设置的第一导光件 41之间，使得第二导 光件 42和第一导光件 41的底面覆盖显示区 100， 第二导光件 42对 图像的放大倍数与第一导光件 41对图像的放大倍数相同。 应当理解的是， 可以采用与设置第一导光件 41相同的方式设置 第二导光件 42， 并且， 可以在同一步骤中同时设置第一导光件 41和 第二导光件 42。 也可以先设置第一导光件 41再设置第二导光件 42。
为了提高包括所述显示面板的终端设备的续航能力， 优选地， 所述制造方法还包括在所述设置第一导光件 41的步骤之前进行如下 步骤：
设置太阳能电池 30 (如图 1 (b)所示） ， 使得该太阳能电池 30 位于第二基板的外表面上。
所述显示面板的第二基板 20的外表面位于第二基板 20的外侧， 将太阳能电池 30设置在第二基板 20的外表面上。
当然， 还可以将太阳能电池 30设置在第一基板 10上， 只要可 以在不影响显示面板正常显示的情况下利用采光面所采集的太阳能 进行发电即可。
为了便于设置所述导光件， 优选地， 所述制造方法还可以包括 在所述设置太阳能电池 30的步骤和所述设置导光件的步骤之间进行 的形成平坦化层 50的步骤， 使得该平坦化层 50覆盖第二基板 20的 外表面和太阳能电池 30， 且平坦化层 50的外表面为平面， 所述导光 件设置在平坦化层 50的外表面上。
容易理解的是， 所述设置太阳能电池 30的步骤和所述形成平坦 化层 50的步骤是在所述设置导光件的步骤之前依次进行的。
如上文中所述， 可以利用热固性树脂或光固化材料来制成平坦 化层 50。 当利用热固性树脂制成平坦化层 50时， 可以先将热固性树 脂涂布在第二基板 20的外表面上，然后对第二基板 20进行加热，使 平坦化层 50固化。当利用光固化材料制成平坦化层 50时，可以先将 光固化材料涂布在第二基板 20的外表面上， 然后利用紫外线进行照 射， 使光固化材料固化而得到平坦化层 50。
同样地， 可以利用光固化材料或热固性树脂形成第一导光件 41 和第二导光件 42。当利用光固化材料形成第一导光件 41和第二导光 件 42时，可先将光固化材料涂布在平坦化层 50的外表面上，然后利 用构图工艺对光固化材料层进行曝光，随后利用刻蚀液使光固化材料 层显影， 形成第一导光件 41和第二导光件 42。 当利用热固性树脂形 成第一导光件 41和第二导光件 42时， 可以先将预成型（未固化）的 第一导光件 41和第二导光件 42设置在平坦化层 50上， 随后进行加 热使第一导光件 41和第二导光件 42固化成型并固定在平坦化层 50 上。
应当理解的是， 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， 这些变型和改进也属于本发明的保护范围。
