Description

一种柔性显示器件的制备方法及装置
技术领域
本发明涉及显示器技术领域，尤其涉及一种柔性显示器件的制备方法及装置。
背景技术
柔性显示器具有诸多优点，例如耐冲击，抗震能力强，重量轻、体积小，携带更加方便等特点。
目前主要的柔性显示材料大致可分为三种：电子纸（或柔性电泳显示）、柔性有机发光二极管（OrganicLightEmittingDiode,OLED）和柔性液晶等。
现有技术中在制备柔性显示器时应用比较多的是贴覆取下法，将柔性基板通过粘结层贴覆在导电硬质基板上，制备完柔性显示器之后再使柔性基板从导电硬质基板上剥离下来，得到柔性显示器。但是，这种剥离方法在操作过程中常常会产生静电无法及时通过导电硬质基板导走，静电会对柔性显示器造成破坏，导致良率下降。
