Description
本发明涉及显示技术领域,尤其涉及一种OLED显示装置及其制作方法。
随着显示技术的发展,平板显示装置因具有高画质、省电、机身薄及应用范围广等优点,而被广泛的应用于手机、电视、个人数字助理、数字相机、笔记本电脑、台式计算机等各种消费性电子产品,成为显示装置中的主流。
有机发光二极管显示器件(Organic Light Emitting Display,OLED)由于同时具备自发光,不需背光源、对比度高、厚度薄、视角广、反应速度快、可用于挠曲性面板、使用温度范围广、构造及制程较简单等优异特性,被认为是下一代平面显示器的新兴应用技术。
OLED显示器件通常包括:基板、设于基板上的阳极、设于阳极上的空穴注入层、设于空穴注入层上的空穴传输层、设于空穴传输层上的发光层、设于发光层上的电子传输层、设于电子传输层上的电子注入层、及设于电子注入层上的阴极。OLED显示器件的发光原理为半导体材料和有机发光材料在电场驱动下,通过载流子注入和复合导致发光。具体的,OLED显示器件通常采用ITO像素电极和金属电极分别作为器件的阳极和阴极,在一定电压驱动下,电子和空穴分别从阴极和阳极注入到电子传输层和空穴传输层,电子和空穴分别经过电子传输层和空穴传输层迁移到发光层,并在发光层中相遇,形成激子并使发光分子激发,后者经过辐射弛豫而发出可见光。
随着科技的发展以及人们对产品的要求的提高,在OLED显示装置在追求高分辨率的同时,也在不断提高屏占比,窄边框技术也得到了快速的发展,在绑定(bonding)侧从原有的直接进行覆晶薄膜(Chip On Film, COF)绑定,已经慢慢的发展为弯折(bending)绑定结构,具体为将绑定端子形成在基板上,柔性电路板绑定到绑定端子上之后弯折到基板的背面,以提升屏占比,实际应用时,柔性电路板的弯折半径越来越小,显示面板的边框也越小,但由于走线结构的限制,弯折半径在实际应用时需要保持在一定范围内,并不能无限的小,始终需要占用一定的边框宽度,由于在弯折时,还容易造成断线不良。
本发明的目的在于提供一种OLED显示装置,能够在不需要弯折的前提下,最大化缩减边框宽度,提升屏占比的同时减少断线风险。
本发明的目的还在于提供一种OLED显示装置的制作方法,能够在不需要弯折的前提下,最大化缩减边框宽度,提升屏占比的同时减少断线风险。

所述OLED显示面板为顶发光型OLED显示面板,其出光面为薄膜封装层远离所述柔性衬底的一侧表面,非出光面为所述柔性衬底远离所述薄膜封装层的一侧表面,所述绑定端子通过穿越所述柔性衬底的第二过孔与所述驱动电路层电性连接。
