Description

显示面板和显示面板的封装方法 技术领域
本申请涉及显示技术领域,尤其涉及一种显示面板和显示面板的封装方法。
背景技术

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,用以例示本申请可用以实施的特定实施例。本申请所提到的方向用语,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申请,而非用以限制本申请。在图中,结构相似的单元是用以相同标号表示。
本申请提供一种显示面板和显示面板的封装方法,以缓解有机发光二极管(OLED)薄膜封装存在隔绝水氧能力不足的技术问题。
本申请实施例提供的显示面板,包括:显示功能层;形成于所述显示功能层上的至少一层无机层;形成于所述显示功能层上、与所述无机层交替设置的缓冲层,其中,至少一层所述缓冲层为金属层。
如图1所示,为本申请的显示面板的第一结构示意图。所述显示面板包括显示功能层、无机层、缓冲层。所述显示功能层包括基板101和设置在所述基板101上的有机发光二极管(OLED)器件102,所述无机层包括第一无机层201、第二无机层202、第三无机层203,所述缓冲层包括第一金属层301、第二金属层302。
所述第一无机层201形成于所述显示功能层上,所述第一金属层301形成于所述第一无机层201上,所述第二无机层202形成于所述第一金属层301上,所述第二金属层302形成于所述第二无机层202上,所述第三无机层203形成于所述第二金属层302上。
在一种实施例中,所述第一金属层301和所述第二金属层302为柔性金属层。在现代通信行业中,手机、电视、平板、笔记本、数码相机等产品市场需求越来越大,各种显示设备也正向可弯折发展,柔性显示面板在使用时经常会反复进行打开、折叠弯曲的操作,由于柔性金属层具有好的延展性和柔性,可以满足柔性屏弯折的需求。
在一种实施例中,所述柔性金属层为铝层、银层或镁层。由于金属薄膜都具有很好的隔绝水氧的能力,在沉积过程中可以填补无机薄膜中的缺陷,通常采用蒸镀、等离子体增强化学气相沉积(PECVD)、化学气相沉积(CVD)、溅镀(sputter)等方法沉积。
在一种实施例中,所述无机层材料为SiNx、SiOx、SiON、SiO 2、Al 2O 3等,通过等离子体增强化学气相沉积(PECVD)、化学气相沉积(CVD)、原子层沉积(ALD)、溅镀(sputter)等方式沉积。
在一种实施例中,至少一层所述缓冲层为有机层。如图2所示,为本申请的显示面板的第二结构示意图。所述显示面板包括显示功能层、无机层、缓冲层。所述显示功能层包括基板101和设置在所述基板101上的有机发光二极管(OLED)器件102,所述无机层包括第一无机层201、第二无机层202、第三无机层203,所述缓冲层包括第一金属层301、第一有机层311。
所述第一无机层201形成于所述显示功能层上,所述第一金属层301形成于所述第一无机层201上,所述第二无机层202形成于所述第一金属层301上,所述第一有机层311形成于所述第二无机层202上,所述第三无机层203形成于所述第一有机层311上。
所述第一有机层311材料主要为SiOC,polymer等,通过等离子体增强化学气相沉积(PECVD)或者喷墨打印(IJP)的方式沉积。所述第一有机层311的作用是增加水氧的渗透通道长度,消除所述无机层间的应力,或者作为平坦化层。
所述无机层起到阻隔水氧的作用,以防止水汽或氧侵入所述显示功能层而造成性能劣化,但无机薄膜在沉积的过程中往往会存在缺陷,隔绝水氧能力不足;有机层可有效降低无机层造成的应力,却增加了水氧入侵的路径,没有隔绝水氧的能力;金属层具有很好的隔绝水氧的能力,在沉积过程中可以填补无机薄膜中的缺陷,且延展性和柔性好;三者的结合使得所述显示面板既能实现柔性功能和显著降低薄膜的应力,又具有良好的阻隔水氧性能,有效延长器件寿命。
根据所述缓冲层材质不同、数量不同、以及设置位置不同,所述显示面板还可以有多种不同的结构。
