1.1 本规程旨在帮助提高在视觉显示单元（如阴极射线管（CRT）和自发光平板显示器）上使用三色刺激色度计进行的色度测量的准确性。它解释了色度数据分析中的一个有用步骤，该步骤利用了这样一个事实，即来自此类显示器的光由三个原色光的相加混合物组成。然而，它并不是关于如何进行此类测量的完整规范。 1.2 本规程仅限于满足规程中定义的线性标准的显示设备和色度仪器。 它不考虑可能导致测量偏差的影响，例如优化的仪器和用于参考的仪器之间的时间或几何差异。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 当使用三刺激色度计测量自发光视频显示设备（例如CRT和平板显示器，包括电致发光（EL）面板、发光二极管（LED）场发射显示器（FED）和背光液晶显示器（LCD））上产生的颜色时，可以应用此实践。本规程并非对测量显示器颜色坐标的过程的完整描述。相反，它提供了一种在满足某些条件时获得更准确结果的方法。任何参与测量显示设备颜色的人员，只要能够使用必要的设备，都可以使用它。 5.2 本规程定义了一类可以说与本规程兼容的三刺激色度计。

1.1 This practice is intended as an aid for improving the accuracy of colorimetric measurements made with tristimulus colorimeters on visual display units, such as cathode ray tubes (CRTs) and self-luminous flat-panel displays. It explains a useful step in the analysis of colorimetric data that takes advantage of the fact that light from such displays consists of an additive mixture of three primary colored lights. However, it is not a complete specification of how such measurements should be made. 1.2 This practice is limited to display devices and colorimetric instruments that meet linearity criteria as defined in the practice. It is not concerned with effects that might cause measurement bias such as temporal or geometric differences between the instrument being optimized and the instrument used for reference. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 This practice may be applied when tristimulus colorimeters are used to measure the colors produced on self-luminous video display devices such as CRTs and flat-panel displays, including electroluminescent (EL) panels, light emitting diodes (LEDs) field emission displays (FEDs), and back-lit liquid crystal displays (LCDs). This practice is not meant to be a complete description of a procedure to measure the color coordinates of a display. Rather, it provides a method for obtaining more accurate results when certain conditions are met. It may be used by any person engaged in the measurement of color on display devices who has access to the requisite equipment. 5.2 This practice defines a class of tristimulus colorimeters that may be said to be compatible with this practice.
