Description

曲面显示面板及曲面显示装置 技术领域
本发明涉及显示技术领域,特别涉及一种曲面显示面板及曲面显示装置。
背景技术
传统的曲面液晶显示器一般是通过以下技术方案来形成的:
将平板贴合的液晶显示器在外力的作用下弯曲,在此过程中依照曲面液晶显示器的设计尺寸以及观赏距离来决定弯曲的程度(曲率半径)。
传统的曲面液晶显示器的CF基板和TFT阵列基板之间一般设置有PS(Photo Spacer,间隔件),所述间隔件用于维持所述CF基板和所述TFT阵列基板之间的间距,从而避免液晶盒(Liquid Crystal Cell)的厚度出现异常。
然而,传统的曲面液晶显示器在从平面状态弯曲为曲面状态时,不可避免地会出现显示屏的不同部位厚度不均的情况,也就是说,显示屏的弯曲过程会使得所述间隔件根据从显示屏的中央区域至左右两边区域的弯曲程度的不同,受到不同程度的压缩。
曲面液晶显示器不同部位的厚度不均匀容易导致显示异常。
故,有必要提出一种新的技术方案,以解决上述技术问题。
