7.Adjustment of White Balance
7.1 Purpose and Principle for adjustment
of the color temperature
- Remote controller for adjustment

- CH : 09 (LCD MNT, Normal) --> M2080A / M2280A/ M2380A
- Auto W/B adjustment instrument(only for Auto adjustment)
- PC (for communication through RGB)
- Pattern Generator (MSPG-925FS series. )
7.2 Connecting diagram of equipment for
measuring (For Automatic Adjustment)
( Standard color coordinate and temperature when using the
CA210 equipment)

* Note : x,y coordinates are drifted about 0.007 after 30 mins
heat-run. So checking color coordinate within 5-min at total
assembly line, consider x,y coordinates might be up to 0.007
than x,y target of each color temperature.
