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: \u2013 gap (physical, optical): detailed splicing precision; \u2013 splicing deviation: splicing accuracy of active areas of LCD splicing screen; \u2013 installation deviation: the flatness of terminal surfaces in vertical and horizontal directions; \u2013 luminance uniformity: luminance uniformity of adjacent LCD units; \u2013 chromatic uniformity: chromatic uniformity of adjacent LCD units.<\/p>\n
