Description

阵列基板及其制作方法、显示装置 技术领域
本发明涉及显示领域,特别涉及一种阵列基板及其制作方法、显示装置。
背景技术
有机电致发光(Organic Lighting Emitting Diode)器件简称OLED,因OLED器件具有自发光,色彩丰富,响应速度快,视角广,重量轻,可做成柔性显示屏等优点而受到广泛关注。然而,在OLED器件制作中,某些制程潜在一些风险,甚至影响到产品的品质。如像素限定层,传统像素限定层是通过一次曝光显影技术制作,该技术虽然较为简单,但形成的像素区域易造成混色,且水氧阻隔性能较差。
现有技术中,针对有机薄膜电致发光器件,其有机电致发光层形成方法有:一、真空蒸镀方法,适用于有机小分子,其特点是有机电致发光层的形成不需要溶剂,薄膜厚度均一,但是设备投资大、材料利用率低、不适用于大尺寸产品的生产;二、采用有机电致发光材料的溶液制成有机电致发光层,包括旋涂、喷墨打印、喷嘴涂覆法等,适用于聚合物材料和可溶性小分子,其特点是设备成本低,在大规模、大尺寸生产上优势突出。特别是喷墨打印技术,能将溶液精准的喷墨到像素区中,形成有机电致发光层。但是其最大的难点是有机电致发光材料的溶液在像素区内难以形成厚度均一的有机电致发光层。
如图6,中国专利CN106784409A中提到在基板上通过喷墨打印或旋涂方式形成像素限定层的第一层第一像素限定层,再利用喷墨打印技术直接形成位于第一膜层下方的、网格状的有机第二膜层,然后去除与网格状的第二膜层的镂空位置对应的第一膜层,从而形成像素限定层,该方法对混色问题无法解决。
如图7,中国专利CN104393192A中提到的像素限定层包括第一像素限定层和层叠在第一像素限定层之上的第二像素限定层,第一个像素限定层的截面呈上窄下宽的正梯形,第二像素限定层的截面呈上宽下窄的倒梯形,第一像素限定层和第二像素限定层分别为亲水的负性光阻和疏水的正性光阻,两层像素限定层通过涂布曝光显影制作,该方法虽然有利于避免阳极和阴极短路以及阴极开路现象,但倒梯形区域蒸镀较为困难,很难满足区域内全部蒸镀上发光材料。
技术问题
现有技术形成像素限定层的区域容易混色,水氧阻隔性能差。

所述阵列层120包括形成于所述基板110上的缓冲层1210、有源层1220、第一绝缘层1230、栅极走线1240、第二绝缘层1250、源极1260、漏极1270和第三绝缘层1280。其中,所述有源层1220设于所述缓冲层1210,所述第一绝缘层1230覆盖所述有源层1220和所述缓冲层1210,所述栅极走线1240设于所述第一绝缘层1230上,所述第二绝缘层1250覆盖所述栅极走线1240,所述源极1260和所述漏极1270设于所述第二绝缘层1250上,所述源极1260和所述漏极1270均与所述有源层1220电性连接,所述第三绝缘层1280覆盖所述源极1260和所述漏极1270。
