电子显示设备—第3-5部分：光学性能评估—色彩能力

[中文适用范围]： 本部分适用于评估电子显示设备的光学性能，特别是其色彩能力。它涵盖了色域、色彩混合以及视角和输入级别对这些因素的影响等各个方面，并提供了测量方法和评价准则。 [外文原描述]： IEC 62977-3-5:2023 specifies standard evaluation methods for determining the colour capabilities of electronic display modules and systems with respect to colour accuracy, colour gamut volume, and their intersection with a reference colour space. Also included is evaluation with respect to the chromaticity gamut area. 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 standard analogue or digital input signals that are not absolute luminance encoded. The input signal is relative RGB without metadata information that codes for real luminance, colour space or colour coordinates. These methods are limited to input signals with typical opto-electronic transfer functions (OETFs) such as defined in IEC 61966‑2‑1, Recommendation ITU-R BT.601 [18] [1] , Recommendation ITU-R BT.709, and Recommendation ITU-R BT.2020. The tests in this document are not suitable for use with HDR input signals. This document contains attached files in the form of Microsoft Excel spreadsheet and App installer. These files are intended to be used as a complement and do not form an integral part of the standard. The content of the corrigendum 1 (2024-10) has been included in this copy.
