• Manufacturer Part Number: ssd1329
• Description: 128 X 128 Oled Segment / Common Driver With Controller Equips With 16 Gray Scale Levels And 64 Hard Icon Lines
• Manufacturer: ETC-unknow

10.3 Set Contrast Current (81h)
This double byte command is to set Contrast Setting of the display. The chip has 256 contrast steps from 00h
to FFh. The segment output current increases linearly with the increase of contrast step
10.4 Set Second Pre-charge Speed (82h)
This command is used to set the speed of second pre-charge in phase 3. This speed can be doubled to achieve
faster pre-charging through setting 82h A[0]. Please refer to Table 9-1 : Command Table for the details of
setting. Figure 10-3 shows the effect of setting second pre-charge under different speeds through using
command 82h.
10.5 Set Master Icon Control (90h)
This double command is used to set the ON / OFF conditions of internal charge pump, icon circuits and
overall icon status.
10.6 Set Icon Current Range (91h)
This double byte command is used to set one fix current range for all icons between the range of 0uA and
127.5uA. The uniformity improves as the icon current range increases. Please refer to Table 9-1 for detail
information and breakdown levels of each step.
