Correlation Between DIN and RadiCS
Pattern Check
Screens without the aspect ratio 1:1 are not applicable since the aspect ratio of the test pattern in
DIN is 1:1. Therefore, RadiCS has patterns with its own solution for each.
Test Pattern 1 The same as Bild 3 pattern. Scaling must be in accordance with a screen
resolution.
Test Pattern 2 The same as Bild 2 pattern. Scaling must be in accordance with a screen
resolution.
Test Pattern 3 The same as Bild 5 pattern. Scaling must be in accordance with a screen
resolution.
Luminance Check
Lmax and Lmin used in DIN include the ambient luminance and are the same as L
’
max and L
’
min
used in RadiCS. Lamb stands for monitor luminance and indicates the same value as “Ls” of DIN.
Lmax/Ls > 100 (or 40) have been Ls > Lmax/100 (or 40). L
’
max/L
’
min stands for contrast ratio.
DIN includes an equality sign like Lmax/Lmin
≥
100 (or 40) but RadiCS does not.
L
’
max and L
’
min come out by measuring the test pattern 2 square with white (grayscale: 255) and
black (grayscale: 0). RadiCS displays 10 % of a display area in the middle and measures luminance
by changing the grayscale 0 to 255.
Uniformity Check
The Uniformity Check judges the uniformity of the ratio between the screen corner and the center of
the screen as a standard. DIN has no particular standard regarding measuring points.
It also displays 10 % display area of the window at grayscale 128 in the middle of the screen and in
the corner of the screen and measures the center of the window.
The basic judgment value (15 % or 20 %) is the same as LCD monitors since RadiForce series
monitors are recommended for RadiCS.
(Lcorner - Lcenter) / Lcenter x 100 < 15 % (or 20%) written on RadiCS means ± 15 % (or ±20%)
and does not include any equality signs.
Sensors
DIN requires a luminance meter class B or higher (DIN 5032-7) for acceptance tests and measuring
devices that does not block environmental light. Sensors for RadiCS that meet those conditions
are LX-Plus, LX-Can, CD-Lux, CD mon and LS-100. Use LX-Plus, LX-Can, CD-Lux, CD mon or
LS-100 for acceptance tests.
DIN allows noncontact sensors only to measure Category B reference value for constancy tests. EIZO
Sensors are available for constancy tests.
