CTA Nationally Adopts LCD Multi-Screen Displays: Measuring Methods
CTA has recently published ANSI/CTA-6009, LCD multi-screen display terminals - Part 2: Measuring methods IEC 63181-2:2020. This standard represents the US National Adoption of IEC 63181-2:2020, which 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
