PTS[2:0]
Set the source output level in non-display area drive period (front/back porch period and blank area
between partial displays).
When PTS[2] = 1, the operation of amplifiers which generates the grayscales other than V0 and V63
are halted and the step-up clock frequency becomes half the normal frequency in non-display drive
period in order to reduce power consumption.

Notes: 1. The power efficiency can be improved by halting grayscale amplifiers and slowing down the step-up clock frequency only in
non-display drive period.
2. The gate output level in non-lit display area drive period is determined by PTG[1:0].
