scope:

This part of IEC 63181 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.
