White balance adjustment
Before adjustment
The unit should be working for above 30 minutes to be in stabler state; Use apparatus CA210 to adjust white balance;
For model of which dimension is bigger than 26”, only 9300K color temperature (that is “normal”) is needed adjustment, To guarantee BBY test requirements to be met when color temperature are 12000K and 6500K, make sure that chromaticity coordinates of bright scale are (X=285±5, Y=293±8) and chromaticity coordinates of dark scale are (X=285±8, Y=293±12); For model of which dimension is 26” or smaller than 26”, only 8000K color temperature (that is “normal”) is needed adjustment, To guarantee test requirements to be met when color temperature are 9300K and 6500K, make sure that chromaticity coordinates of bright scale are X=295±5, Y=305±8) and chromaticity coordinates of dark scale are (X=295±8, Y=305±12);
White balance adjustment of HDMI
Input 16-grey-scale signal with format of 800×600/60 Hz (VG848: Timing is 854
PAT is 921), enter into submenu “color temperature adjustment” of factory menu; For model of which dimension is bigger than 26”, select “normal” color temperature (that is 9300K), fix item “G Offset”, adjust items “R Offset, B Offset” to set chromaticity coordinates of the 3rd scale as 285±8, 293±12 and guarantee luminance within the range of 3 nit to 5 nit; fix item “G GAIN”, adjust items “R GAIN, B GAIN” to set chromaticity coordinates of the reverse 3rd scale as 285±8, 293±12 ; adjust items “R Offset, B Offset” and “R GAIN, B GAIN” repeatedly until chromaticity coordinates of both scales are all 285, 293
For model of which dimension is 26” and small than 26”, select “normal” color temperature (that is 8000K), fix item “G Offset”, adjust items “R Offset, B Offset” to set chromaticity coordinates of the 3rd scale as
295±8, 305±12 and guarantee luminance within the range of 3 nit to 5 nit; fix item “G GAIN”, adjust items “R GAIN, B GAIN” to set chromaticity coordinates of the reverse 3rd scale as 295±5, 305±8 ; adjust items “R Offset, B Offset” and “R GAIN, B GAIN” repeatedly until chromaticity coordinates of both scales are all 295, 305; Set item “ALL COLOR” as “ON” after completing adjustment.
