Description

显示器及其制造方法 技术领域
本发明涉及一种显示器领域,尤其涉及一种显示器的柔性膜减薄技术。
背景技术
目前柔性主动矩阵有机发光二极体(active-matrix organic light-emitting diode,AMOLED)显示屏100生产工艺过程中,首先会在玻璃基板110上涂覆一层聚酰亚胺(PI)120作为衬底,之后在PI层120上进行晶体管数组130的制程,如图1所示。随着全面屏手机的市场需求日益提高,对手机黑边宽度要求越来越高。因此在模组段,PI层120及集成电路(IC)140将弯折至基板背面以达到减少手机边缘黑边宽度的目的,如图2所示。然而,上述弯折存在一个技术风险:如图3所示,PI层120在弯折过程中存在较大内应力,PI层120容易变形并传递应力,导致分布其上的金属走线150受到压力而变形或折断,进而引起线路接触异常,导致AMOLED显示区信号异常,影响AMOLED发光稳定性,降低产品良率。
技术问题
为了解决显示器在弯折过程中,柔性层(例如PI层)产生较大内应力,导致分布其上的金属走线受到压力而变形或折断的问题,亟需一种可将在显示器的弯折区的柔性膜减薄的技术。
技术解决方案
有鉴于此,本发明提供一种新的显示器及其制造方法,藉由在进行柔性层(例如PI层)成膜前先将刚性基板(例如玻璃基板)图案化,形成柔性层预留凹槽,在柔性层涂膜过程中,柔性层同时在预留图案区域下陷,但成膜厚度不变。在之后模组工艺中,利用雷射切割,将基板图案中的柔性层切除,使柔性层成功减薄。这样设计的优点在于玻璃图案化所需蚀刻区域小,工艺简单,易于实现。同时通过控制图案化凹槽深度可以进行不同厚度的柔性层减薄要求,达到防止走线断裂,提升良率的目的。除此之外,后续晶体管数组工艺不需要增加光罩,减少了工艺难度和成本。
据此,依据本发明的一实施例,本发明提供了一种显示器的制造方法,包括以下步骤:
