3) Super Power Saving Mode
This uses the Multi APC function of the PDP module, and aims at reducing power consumption more than 100 W for the white
pattern, which is similar to the power consumption reduction of other manufacturers.
- Concept of Multi APC
: Controls the number of sustain pulses according to the ASL (Average Signal Level) by R_P_Lower_Gain value.
In the PDP Logic, R_Multi_APC is set to 0X01, Multi_APC operates, and R_P_CM_Gain_SW is set to 0X01 so that the
upper and lower limits of the APC Table can be shifted by adjusting the R_P_Lower_Gain value only.
Therefore, the sustain pulse is controllable for the white pattern, even though it was formerly not controllable.
※ Caution: The Super Power Saving Mode screen is darker than that of Standard Mode.
