技术问题
然而由于直接在显示区域设置孔,会使得孔内的膜层裸露在外,降低显示屏的封装效果,缩短了显示屏的使用寿命。
因此,有必要提供一种显示屏及电子装置,以解决现有技术所存在的问题。

显示单元,设置在所述第一基部上;
封装层,设于所述显示单元上并用于封装所述显示单元;
保护层,至少覆盖所述封装层的透光端部和所述显示单元的透光端部,其中所述透光端部为靠近所述透光区域侧的端部。
本发明还提供一种电子装置,其包括上述显示屏。
有益效果
本发明的显示屏及电子装置,通过在至少所述封装层的透光端部和所述显示单元的透光端部覆盖保护层,使得封装层和显示单元靠近透光区域侧的端部可以阻挡水氧的入侵,从而提高了显示屏的封装效果以及延长了显示屏的使用寿命。

结合图2,本实施例的显示屏包括衬底基板10、显示单元200,封装层40以及保护层50。
所述衬底基板10包括第一基部11,第一基部11设置在所述透光区域103外,也即所述第一基部11与所述显示区域101的位置对应。第一基部11包括左右两侧间隔设置的衬底基板,其中所述第一基部11包括间隔设置的第一子部(左侧部分)和第二子部(右侧部分),所述第一子部和所述第二子部之间的间隙的位置与所述透光区域103的位置对应。本实施例的透光区域103为通孔。其中透光区域103的截面形状为长方形。
显示单元200可包括开关阵列层20和有机发光显示层30,显示单元200设置在所述第一基部11上。所述开关阵列层20设于部分位于所述显示区域101的衬底基板10上;且靠近所述透光区域103侧的衬底基板10上未覆盖所述开关阵列层20。也即所述开关阵列层20部分覆盖在第一基部上。其中所述开关阵列层20包括间隔设置的第一开关部21和第二开关部22;所述第一开关部21和所述第二开关部22之间的间隙与所述透光区域103的位置对应。所述开关阵列层20包括多个薄膜晶体管,所述开关阵列层20的截面结构可包括多层金属层,所述金属层包括多条信号线,其中信号线的位置与所述透光区域103的位置不对应,也即所述第一开关部21和所述第二开关部22均设置有多条信号线,其中信号线包括数据信、扫描线等,以提高显示屏的稳定性。比如,在制作过程中,可以先制作整层的开关阵列层,之后将与透光区域位置对应的开关阵列层去除。
有机发光显示层30设于部分所述开关阵列层20上;且靠近所述透光区域103侧的开关阵列层20上未覆盖有机发光显示层30。有机发光显示层30可包括阳极、有机发光层以及阴极。在俯视角下,有机发光显示层30包括可多个有机发光单元。
封装层40设于所述有机发光显示层30、部分未被所述有机发光显示层30覆盖的开关阵列层20上。其中所述封装层40的截面结构为无机有机交替的结构。当然所述封装层40可以设于整个未被所述有机发光显示层30覆盖的开关阵列层20上。也即封装层40靠近透光区域103侧的端部与开关阵列层20靠近透光区域103侧的端部齐平。
其中为了进一步提高封装效果,所述封装层40包括间隔设置的第一封装部41和第二封装部42,所述第一封装部41和所述第二封装部42之间的间隙与所述透光区域103的位置对应,所述第一封装部41和所述第二封装部42之间的间隙大于或等于所述第一开关部21和所述第二开关部22之间的间隙。也即此时,封装层40部分设置在未被所述有机发光显示层30覆盖的开关阵列层20上。
所述保护层50覆盖所述封装层40的透光端部和所述显示单元200的透光端部,此外还覆盖在封装层40上。其中保护层50设于所述封装层40、未被所述封装层40覆盖的开关阵列层20以及未被所述开关阵列层20覆盖的第一基部11上。其中,所述保护层50覆盖所述开关阵列层20的透光端部和所述封装层40的透光端部,其中所述透光端部为靠近所述透光区域103侧的端部。其中所述保护层50用于阻隔水氧。
在一实施方式中,所述保护层50的材料为透明光学胶。由于透明光学胶流动性较好,因此可使显示屏的表面更加平坦。透明光学胶中可以添加吸湿剂,以提高其隔绝水气的能力。
在另一实施方式中,所述保护层50的材料为无机材料,比如可以是SiN、SiO、SiON或其他无机材料,可利用ALD等方法制作。由于无机材料有较好的水气隔绝能力,从而可以更好地防止水氧入侵。当然,可以理解的保护层的材料也可为其他材料。
所述保护层50包括间隔设置的第一保护部51和第二保护部52,所述第一保护部52和所述第二保护部52之间的间隙与所述透光区域103的位置对应,且所述第一保护部51和所述第二保护部52之间的间隙处在所述衬底基板10上的正投影面积等于所述透光区域103在所述衬底基板10上的正投影面积。
为了进一步提高封装效果,也即防止外界的水氧对所述开关阵列层造成损坏,所述第一开关部21和所述第二开关部22之间的间隙大于所述第一保护部51和所述第二保护部52之间的间隙。也即使得保护层50包覆在所述开关阵列层20靠近透光区域侧103的端部外。
为了进一步提高封装效果,所述第一子部和所述第二子部之间的间隙等于所述第一保护部51和所述第二保护部52之间的间隙。
所述显示屏还可包括偏光片60,所述偏光60片设于所述保护层50上。其中与所述透光区域103对应的位置未设置所述偏光片60。
所述显示屏还可包括玻璃盖板70,所述玻璃盖板70设于所述偏光片60上,且所述玻璃盖板70覆盖所述透光区域103。也即所述玻璃盖板70覆盖整个显示屏。
由于在所述封装层、未被所述封装层覆盖的开关阵列层以及未被所述开关阵列层覆盖的第一基部上设置保护层,使得在封装层和或开关阵列层的上方以及封装层靠近透光区域侧的端部和开关阵列层靠近透光区域侧的端部均覆盖有保护层,从而阻止外界的水氧入侵,防止薄膜晶体管受到损坏,提高了器件的性能,进而提高了封装效果,且延长了像素的使用寿命。
请参照图3,图3为实施例二沿图1中的A-A’线的第一种剖面图。
结合图3,在另一实施例中,本实施例与上一实施例的区别在于,所述衬底基板10还包括第二基部12,所述第二基部12与所述透光区域103的位置对应。所述第一基部11和所述第二基部12相互抵接。也即本实施例的透光区域103为盲孔。
其中,为了防止透光区域漏光而影响显示效果,结合图4,所述透光区域103的周缘处也设置有保护层50。
其中,为了进一步防止透光区域漏光而影响显示效果,结合图5,所述透光区域103内也填充有保护层50,也即所述第二基部12上也设置有所述保护层50。
第一实施例和第二实施例的显示屏是通过逐层制作得到的,也即在透光区域对应的位置未制作显示单元、封装层以及偏光片等。
请参照图6,图6为实施例三沿图1中的A-A’线的第一种剖面图。
如图6所示,本实施例的显示屏与第一实施例的区别在于:所述保护层50还覆盖偏光片60的透光端部和/或第一基部11的透光端部。也即所述保护层50设置在透光区域103的两侧。当然,也可在所述封装层40的透光端部和所述显示单元200的透光端部设置保护层50。也即所述保护层50设置在透光区域103的两侧中的部分区域。
为了进一步阻止外界的水氧入侵,如图7所示,与所述透光区域103对应的玻璃盖板70的下方也设置有保护层50。此外还可在第一基部11的下方也设置保护层50。也即,所述保护层50设于所述透光区域103的周缘外。
为了进一步阻止外界的水氧入侵,如图8所示,所述透光区域103内也填充有保护层50。本实施例的透光区域103的截面形状为梯形,可以理解的,透光区域的形状并不能对本发明构成限定。
在具体制作过程中,可以在完成盖板下方的显示面板后,利用激光切割工艺将透光区域103对应的部分切割去除,之后再将盖板与切割后的显示屏进行贴合。之后在切割线的边缘(透光区域的两侧)制作保护层。其中保护层50的厚度可以在数十到数百微米。
由于将在所述封装层的透光端部和所述显示单元的透光端部、以及偏光片和第一基部的透光端部均覆盖保护层,更好地阻挡水氧的入侵,从而提高了显示屏的封装效果以及延长了显示屏的使用寿命。
本发明还提供一种电子装置,其包括上述任意一种显示屏。该电子装置可以为手机、平板电脑等设备。
在一实施方式中,如图9和10所示,其中该电子装置还包括摄像头200,所述摄像头200的位置与所述透光区域103的位置对应,且所述摄像头200朝向所述显示屏的显示面设置。
本发明的显示屏及电子装置,通过在至少所述封装层的透光端部和所述显示单元的透光端部覆盖保护层,使得封装层和显示单元靠近透光区域侧的端部可以阻挡水氧的入侵,从而提高了显示屏的封装效果以及延长了显示屏的使用寿命。
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。
