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