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。
 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。所述显示面板包括基板10、薄膜晶体管层20、发光层30、封装层40以及彩膜层。所述发光层包括多个像素点。所述彩膜层包括多个滤光片，所述多个滤光片与所述多个像素点一一对应。图1中示出了绿色彩膜层52、红色滤光片54和蓝色滤光片56。所述彩膜层还包括多个挡光单元58，用于隔离显示屏表面的相邻像素点。
参见图1，大视角时，像素点34发出的光线沿路径A先后经过红色彩膜层54和绿色彩膜层52，导致红色画面偏黄；沿路径B先后经过红色彩膜层54和蓝色彩膜层56，导致红色画面偏紫。在液晶显示面板中，由于背光光源和彩膜层之间必须存在一定的混光距离，色偏现象更加严重。
因此，本发明提供了一种显示面板和电子设备，以消除显示面板在大视角时出现的色差现象。参见图2，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。所述显示面板包括板10、薄膜晶体管层20、发光层30、封装层40以及彩膜层。所述显示面板可以是液晶面板，也可以是OLED面板。液晶面板和OLED面板的不同之处在于发光的方式不同。本发明的发明点在于对彩膜层的结构进行改进，无论是液晶面板还是OLED面板，都可以采用本发明的技术方案。
所述基板10 可以是硬质基板，例如玻璃基板、金属基板等；也可以是柔性基板，例如有机或无机聚合物，常用作柔性基板的聚合物为聚酰亚胺。在本实施例中，所述基板优选的为玻璃基板。
所述发光层包括多个像素点。所述彩膜层包括多个滤光片，所述多个滤光片与所述多个像素点一一对应。图2中示出了绿色彩膜层52、红色滤光片54和蓝色滤光片56，以及与所述绿色彩膜层52对应的第一像素点32、与红色滤光片54对应的第二像素点34和与蓝色滤光片56对应的第三像素点36。所述彩膜层还包括多个挡光单元58，用于隔离显示屏表面的相邻像素点。

为了消除色偏现象，本发明的显示面板中还设置了多个光线转换单元60，参见图2，所述多个光线转换单元60位于任意两个相邻的彩膜单元的交界处下方。
在本实施例中，任意两个相邻的光线转换单元60的边界之间的最小距离大于或等于任意两个相邻的发光单元的边界之间的距离。参见图2，为了确保光线转换单元60能够有效的遮挡光线，避免光线射向相邻的滤光片而非位于其正上方的滤光片，所述光线转换单元60的宽度大于任意两个相邻的像素点之间的最短距离。即，所述光线转换单元60在发光层30上的投影的边界应该落入相邻的像素点的发光单元中。
为了优化制造工艺，同时进一步提高显示效果，所述多个挡光单元58位于所述多个光线转换单元60上方，并且与所述多个光线转换单元60一一对应。优选的，在本实施例中，所述挡光单元58在所述基板10上的投影与所述光线转换单元60在所述基板10上的投影相等。
在本实施例中，为了简化工艺并节约成本，所述多个挡光单元60的厚度相等，且所述厚度小于或等于所述彩膜单元的厚度。在其他实施例中，所述多个挡光单元60可以设置多个厚度。
在本实施例中，构成所述光线转换单元60的材料包括量子材料，在本实施例中，所述量子材料包括量子点薄膜。量子点薄膜对可见光有很强的吸收作用，能够有效的吸收射入其中的可见光，并将所述可见光转换为肉眼不可见的红外线或紫外线。具体的，所述量子点薄膜包括二六族元素或三五族元素组成的半导体纳米微粒，例如砷化镓纳米薄膜、氧化硅纳米薄膜、硫化锌纳米薄膜等。在其他实施例中，也可以采用石墨烯制作所述光线转换单元60。在本发明中，所述半导体纳米微粒的直径大于10纳米，小于100纳米，例如，所述半导体纳米微粒的直径为40纳米、50纳米或60纳米。
形成所述半导体纳米微粒的方法包括转印、网印、喷墨打印、电流体印刷和光刻工艺中的任意一种。根据制造工艺的不同，所述半导体纳米微粒的直径可以相等，也可以不相等。
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。
本发明提供的显示面板设置了多个光线转换单元，所述多个光线转换单元位于任意两个相邻的彩膜单元的交界处下方。所述光线转换单元为量子薄膜。在观看视角较大时，量子薄膜能将射向所述量子薄膜的光线转换为红外线等不可见光，从而避免相邻的像素点之间的光线发生混光现。
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。
