电子显示屏作为信息传递的媒介，其出现在人们生活的方方面面，随着人们生活水平的提高，人们平均使用电子显示屏的时间也越来越长。
然而，用户长时间使用电子显示屏会对用户的眼睛造成损害。
因此，如何减少用户长时间使用电子显示屏造成的视力损害的本领域技术人员亟需解决的问题之一。
发明内容
本申请实施例提供了显示方法和装置，能够减少用户长时间使用电子显示屏造成的视力损害。为达到上述目的，本申请实施例采用如下技术方案：
第一方面，本申请实施例了一种显示方法，应用于电子设备，所述电子设备包括显示屏，该方法包括：首先获取环境信息。然后根据所述环境信息确定所述环境光的显示信息。之后根据环境光的显示信息调整所述显示屏的显示亮度和显示色温。其中，所述环境信息包括所述环境光的亮度和所述环境光的色温；所述显示信息包括所述环境光的亮度对应的亮度范围和所述环境光的色温对应的色温范围。
可以看出，本申请实施例提供显示方法可以根据环境光的亮度和环境光的色温，调整显示屏的色温和亮度，从而调整色温和亮度后的显示屏对用户眼睛更加友好，从而减少用户长时间使用电子显示屏造成的视力损害。
例如，可以根据环境光的亮度和环境光的色温，调整显示屏的色温和亮度使显示屏显示的内容与同环境下印刷纸张表现一致。可以理解的是，显示屏显示的内容越接近纸张的表现，阅读舒适性则越佳，越不易眼疲劳。因此调整显示屏的色温和亮度使显示屏显示的内容与同环境下印刷纸张表现一致，可以减少用户长时间使用电子显示屏造成的视力损害。
可选地，所述环境光的亮度对应的亮度范围大于或等于第一亮度阈值且小于或等于第二亮度阈值。即第一亮度阈值≤环境光的亮度对应的亮度范围≤第二亮度阈值。
可选地，所述环境光的色温对应的色温范围大于或等于第一色温阈值且小于或等于第二色温阈值。即第一色温阈值≤环境光的亮度对应的亮度范围≤第二色温阈值。
