Abstract
本发明提供一种显示面板及电子装置,该显示面板包括:驱动基板;绝缘层,设置有第一容置槽和第二容置槽;第一微型发光二极管,设置在所述第一容置槽内;第二微型发光二极管,设置在所述第二容置槽内,所述第二微型发光二极管的上方设置有第一反射层。本发明的显示面板及电子装置,能够减小显示面板的厚度。
Description
【技术领域】
本发明涉及显示技术领域,特别是涉及一种显示面板及电子装置。
【背景技术】
双面显示面板是指正反面均设置有显示屏,其中正面为主面板而背面为副面板,主面板通常为全面板设计。当正面的面板点亮时,背面的面板关闭也即为熄屏状态,背面的面板处于熄屏板状态下可以作为背板,这样在一定程度上降低了功耗。
现有的自发光双面显示面板通常包括两块显示面板,之后再将两块显示面板的背面贴合在一起或者组合在一起。这种双面显示面板虽然能够实现双面显示,但是由于需要采用两块显示面板,导致厚度较大。
【发明内容】
本发明的目的在于提供一种显示面板及电子装置,能够减小显示面板的厚底。
为解决上述技术问题,本发明提供一种显示面板,其包括:
驱动基板;
绝缘层,设置有第一容置槽和第二容置槽;
第一微型发光二极管,设置在所述第一容置槽内;
第二微型发光二极管,设置在所述第二容置槽内,所述第二微型发光二极管的上方设置有反射层。
本发明还提供一种电子装置,其包括上述显示面板。
本发明的显示面板及电子装置,由于在单个显示面板上设置两个微型发光二极管,且在第二微型发光二极管的上方设置有第一反射层,因此使得第二微型发光二极管的光线朝向显示面板的背面出射,从而实现了双面显示,由于不需要两个显示面板,因此减小了显示面板的整体厚度。
【附图说明】
图1为本发明显示面板的结构示意图;
图2为本发明显示面板的俯视图;
图3为本发明显示单元的电路图。
【具体实施方式】
以下各实施例的说明是参考附加的图式,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,结构相似的单元是以相同标号表示。
如图1和2所示,本发明的显示面板100为双面显示面板。
本发明的显示面板100的包括驱动基板10、绝缘层20、第一微型发光二极管31以及第二微型发光二极管32。所述显示面板100还可包括平坦层50。
其中驱动基板10的截面结构包括衬底基板11、开关阵列层12以及像素电极13。
开关阵列层12位于衬底基板11上,其包括多个薄膜晶体管。
像素电极13位于开关阵列层12上。像素电极13的材料可为ITO。
绝缘层20设置有第一容置槽21和第二容置槽22。在一实施方式中,为了提高对比度,所述绝缘层20的材料为遮光材料,比如为黑色光阻材料。
第一微型发光二极管31设置在所述第一容置槽21内。
第二微型发光二极管32设置在所述第二容置槽22内,所述第二微型发光二极管32的上方设置有第一反射层41。其中为了提高显示效果,所述第一反射层41覆盖所述第二容置槽22。也即在所述第一反射层41在衬底基板11上的投影面积大于所述第二容置槽22在衬底基板11上的投影面积。
其中为了减小显示面板的尺寸,所述第一微型发光二极管31和所述第二微型发光二极管32相邻。其中为了简化制程工艺,所述像素电极13覆盖所述第一微型发光二极管31和所述第二微型发光二极管32,且所述第一微型发光二极管31和所述第二微型发光二极管32均与所述像素电极13电性连接。也即两个微型发光二极管共用像素电极,不仅可以减小线路的排布数量,且使得电流的控制更加精准,进而提升画面颜色的精准度。
为了提高光线的利用率,在一实施方式中,所述第二容置槽22的侧壁上也设置有第二反射层42。
为了进一步提高光线的利用率,在一实施方式中,所述第一容置槽21的侧壁上也设置有第三反射层43。其中第一反射层、第二反射层、第三反射层的材料可相同。在一实施方式中,第一反射层41、第二反射层42、第三反射层43在同一制程工艺中制得的。
结合图3,所述驱动基板10还包括第一薄膜晶体管T1和第二薄膜晶体管T2;所述第一薄膜晶体管T1的栅极接入第一扫描信号S1,其源极接入第一数据信号M1,其漏极与所述第二薄膜晶体管T2的栅极连接;所述第二薄膜晶体管T2的源极与电源负电压VSS连接,其漏极与所述第一微型发光二极管31的阴极连接。此外所述驱动基板10还可包括第一电容C1,第一电容C1的一端与所述第一薄膜晶体管T1的漏极连接,第一电容C1的另一端与所述第二薄膜晶体管T2的源极连接。
所述驱动基板10还包括第三薄膜晶体管T3和第四薄膜晶体管T4;所述第三薄膜晶体管T3的栅极接入第二扫描信号S2,其源极接入第二数据信号M2,其漏极与所述第三薄膜晶体管T3的栅极连接;
所述第四薄膜晶体管T4的源极与电源负电压VSS连接,其漏极与所述第二微型发光二极管32的阴极连接。此外所述驱动基板10还还可包括第二电容C2,第二电容C2的一端与所述第三薄膜晶体管T3的漏极连接,第二电容C2的另一端与所述第四薄膜晶体管T4的源极连接。
其中所述第一微型发光二极管31的阳极和所述第二微型发光二极管32的阳极均接入电源正电压VDD。
所述平坦层50设置在显示面板的顶部,所述平坦层50的材料可为绝缘材料。
由于在单个显示面板上设置两个微型发光二极管,且第二微型发光二极管的上方设置有反射层,因此使得第二微型发光二极管的光线朝向显示面板的背面出射(也即下方,具体如图1中箭头方向所示),而第一微型发光二极管发出的光线朝向显示面板的正面,因此实现了双面显示;由于不需要两个显示面板,因此减小了显示面板的整体厚度。此外还可降低生产成本。
本发明还提供一种电子装置,其包括上述显示面板,该电子装置可以为手机、平板电脑等设备。
本发明的显示面板及电子装置,由于在单个显示面板上设置两个微型发光二极管,且在第二微型发光二极管的上方设置有第一反射层,因此使得第二微型发光二极管的光线朝向显示面板的背面出射,从而实现了双面显示,由于不需要两个显示面板,因此减小了显示面板的整体厚度。
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。
