SDR HDR XDR All In One

XDR、HDR、SDR 是显示技术中用于描述画面动态范围对比度色彩表现)的三个核心概念,代表了从标准极致的演进过程。

  1. SDR(标准动态范围,Standard Dynamic Range)定义:
    传统电视和显示器常用的格式,最大亮度通常限制在 100-300 尼特左右。
    特点: 色彩和亮度范围有限,暗部细节容易丢失,画面表现偏平。
    适用: 日常网页浏览、观看老电影或标准有线电视。

  2. HDR(高动态范围,High Dynamic Range)定义:
    相比 SDR,HDR 能大幅拓宽亮度和色彩范围。其峰值亮度通常在 400-1000 尼特以上,包含 HDR10、杜比视界(Dolby Vision)等多种格式。
    特点: 极大增强画面的对比度,同时保留高光与阴影细节,色彩更生动自然,接近人眼真实视觉。
    适用: 现代高清流媒体电影、游戏主机与 PC 游戏。

  3. XDR(极致动态范围,Extreme Dynamic Range)定义:
    由苹果(Apple)公司提出的概念与标准,代表超越传统 HDR 的极限显示性能。例如其 Pro Display XDR 显示器可持续峰值亮度可达 1000 尼特,局部峰值亮度高达 1600 尼特
    特点: 结合了先进的背光技术(如 Mini-LED)和面板工艺,提供极高的对比度、超高亮度和极其宽广的色彩表现。
    适用: 苹果生态中的专业影视后期制作、高端视觉设计领域。
