标准摘要
[中文适用范围]： 本部分IEC 63181规定了LCD多屏显示终端的测量方法。 为评估LCD多屏显示终端的特性，规定了以下测量项目： - 间隙（物理、光学）：详细的拼接精度； - 拼接偏差：LCD拼接屏活动区域的拼接精度； - 安装偏差：终端表面在垂直和水平方向上的平整度； - 亮度均匀性：相邻LCD单元的亮度均匀性； - 色度均匀性：相邻LCD单元的色度均匀性。 [外文原描述]： IEC 63181-2:2020 specifies measuring methods for LCD multi-screen display terminals. To evaluate the characteristics of LCD multi-screen display terminals, the following measurement items are specified: – gap (physical, optical): detailed splicing precision; – splicing deviation: splicing accuracy of active areas of LCD splicing screen; – installation deviation: the flatness of terminal surfaces in vertical and horizontal directions; – luminance uniformity: luminance uniformity of adjacent LCD units; – chromatic uniformity: chromatic uniformity of adjacent LCD units.
