Description

显示装置及显示方式
本申请要求于2020年06月09日提交中国专利局、申请号为202010517931.4、发明名称为“显示装置及显示方式”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及显示技术领域，尤其涉及一种显示装置及显示方式。
 背景技术
随着显示技术的不断发展，人们看到的显示屏上的画面也更加的多彩绚丽。然而，在显示屏长时间显示一静止画面时，会导致显示屏中常亮的地方亮度衰减比其他地方大。从而，当显示其它画面时，会看到静止的画面残留影像，称为残影现象。
例如有机发光二极管显示屏长时间定格在同一地方时，常亮的地方亮度衰减往往比其他地方大，其中对比度较高的地方切换画面后会产生残影；如果静止画面时间过长，导致像素点老化严重，则会对显示屏造成无法挽回的烧屏。目前面板厂商虽然采取了自动刷新像素面板或自动降低静止画面亮度的方法来应对烧屏问题，但是这些方法只能缓解残影或烧屏现象，而无法从根本上解决。
