IEC 62977-3-4:2023规定了用于确定HDR电子显示模块和系统的光学特性的标准评估方法。这些方法适用于在平面面板或局部曲率半径大于1500 mm的曲面面板上渲染真实2D图像的发射型和透射型直视显示器。本文件评估了这些显示器在暗室条件下的光学特性。本文件适用于响应于被绝对亮度编码的HDR数字输入信号的显示性能的测试，例如包括建议ITU的RGB分量值的HDR信号- R BT.2020比色法，具有SMPTE ST 2084 PQ亮度编码和SMPTE ST 208 6元数据。

IEC 62977-3-4:2023 specifies the standard evaluation methods for determining the optical characteristics of HDR electronic display modules and systems. These methods apply to emissive and transmissive direct-view displays that render real 2D images on a flat panel or on a curved panel with a local radius of curvature larger than 1 500 mm. This document evaluates the optical characteristics of these displays under darkroom conditions. This document applies to the testing of display performance in response to HDR digital input signals that are absolute luminance encoded such as the HDR signal comprising RGB component values of Recommendation ITU-R BT.2020 colorimetry with SMPTE ST 2084 PQ luminance encoding and SMPTE ST 2086 metadata.
