Description

发光模组及显示装置 技术领域
本申请涉及显示技术领域,具体涉及一种发光模组及一种显示装置。
背景技术
随着技术的进步和消费电子产品的迭代,用户也越来越关注隐私保护的问题。目前,现有防窥显示技术都是对显示面板的整个显示画面进行防窥视处理。然而,全画面防窥视用户使用时可支配的灵活度较低,特别对于大尺寸长屏,由于只能全面防窥视,在显示屏的两个局部区域需要分别进行防窥视和分享时,全面防窥视的显示屏无法实现该功能。
因此,在大多数车企中,多采用三联屏或者双联屏的方式,即用同一盖板贴附多个单独的屏体,对需要进行防窥的副屏做单独处理,然而,这种方式使得屏与屏中间存在明显可视的边界,影响用户的观看体验。
