Description
VP7 ~ VP0
Vertical start position control ( = VP[7:0]
×
4)
Signifies top margin height from the V-Sync reference edge.
Horizontal start position control ( = HP[7:0]
×
6)
Signifies delay of the horizontal display from the H-Sync reference edge
to the character's 1st pixel location.
The contrast adjustment is made by contrdling simultaneously the gain
of three internal variable gain amplifiers.
The contrast adjustment allows to cover a typical range of 38dB.

VC7 ~ VC0
(bit7 ~ 0)
BRT7 ~ BRT0
(bit7 ~ 0)
The brightness adjustment controls to add the same black level
(pedestal) to the 3-channel R/G/B signals after contrast amplifier.
RSB7 ~ RSB0
(bit7 ~ 0)
R channel SUB contrast control.
The SUB contrast adjustment is used to adjust the white balance, and
the gain of each channel is controlled.
The SUB contrast adjustment allows you to cover a typical tange of
12dB.
G channel SUB contrast control.
The SUB contrast adjustment is used to adjust the white balance, and
the gain of each channel is controlled.
The SUB contrast adjustment allows you to cover a typical tange of
12dB.
B channel SUB contrast control.
The SUB contrast adjustment is used to adjust the white balance, and
the gain of each channel is controlled.
The SUB contrast adjustment allows you to cover a typical tange of
12dB.
The OSD contrast adjustment is made by contrdling simultaneously the
gain of three internal variable gain amplifiers.
The OSD contrast adjustment allows to cover a typical range of 38dB.
