Warm : Backlight 30
** In the case of LED Model, Measure the color
temperature at the warm mode after heat run T.V
more than 60 minutes at Cinema mode.
Color Space : After 90min heat run, test the Color Space Spec
Luminance : After 90min heat run, test the Luminance Spec
Color Temperature measure standard specification
▣ Color Temperature measure specification
1)
In non-impressed condition, measure White Balance displayable as much as possible LCD module.
2)
Measuring instrument: CA-210 or a sort of Color Analyzer.
3)
Pattern Generator : VG-828 or a sort of digital pattern generator (204 Gray)
4)
Measure condition
● Test pattern: 85% Full White pattern
● SET condition : Contrast & Brightness Level 100%
● Environment condition : Dark room in the non outside light
● Video menu option condition
