8-4. LCD Blue Brightness Adjustment
Adjusting method:
1. Adjust LCD “B Bright” so that the amplitude of the CL404
waveform is VG
±
0.05 Vp-p with respect to the CL403 (VG)
waveform.
Note:
8-2. LCD RGB Offset adjustment and 8-3. LCD Gain adjust-
ment should always be carried out first.
8-5. LCD Red Brightness Adjustment
Adjusting method:
1. Adjust LCD “R Bright” so that the amplitude of the CL402
waveform is (VG – 0.1)
±
0.05 Vp-p with respect to the CL403
(VG) waveform.
Note:
8-2. LCD RGB Offset adjustment and 8-3. LCD Gain adjust-
ment should always be carried out first.
8-6. LCD VcomPP Adjustment
Adjusting method:
