摘要
在介绍室内和室外环境光照度标准值要求的基础上,包括室外不同天气条件、不同时间的环境光标准值要求,阐述了显示屏环境光对比度测量的重要性。介绍了VESA和NISTIR等国际标准推荐的测量方法,包括搭建环境光使用的仪器设备、测量信号和测量步骤。同时对两种国际标准推荐的测量方法进行比较分析,并运用VESA标准推荐的测量方法进行举例说明。
The indoor and outdoor ambient illumination requirements of the standard value is described in this paper, including the outdoor requirements of the standard value in different weather conditions and different times. Based on these introductions, the importance on ACR testing is expatiated. And the measurement methods which are recommended in VESA and NISTIR introduced, including instrument which is used for establishing ambient illuminantion, testing signal and testing step. At the same time, the writer compares with the measurement methods which the two international standards recommend and illustrates using VESA standard.
