setting. Be sure to avoid using such as extremely changing the CLK frequency (ex. CLK stop).
9. SRC AND HIGH DRIVE TIME
When the STB is high level, all outputs became Hi-Z and the gray-scale voltage is output to the LCD in synchronization
Therefore, high drive time of the output amplifier as below is determined by the CLK number of the required SRC pin
The
We recommend a thorough simulation of the output amplifier in advance when set the SRC pin.

PD160061A can control high drive time of the output amplifier by SRC pin logic (refer to below figure).
SRC = H or open (high drive time: standard mode): High drive time (PWhp) of the output amplifier is in 64 CLK
SRC = L (high drive time: long-term mode): High drive time (PWhp) of the output amplifier is in 128 CLK period
