We recommend a thorough simulation of the output amplifier in advance, when set the LPC and HPC pins.
Refer to the table below for the example of the combination of setting level and panel load, with driver part supply voltage.

Example of Condition
Load: RL = 5 kΩ, CL = 75 pF
Driver part supply voltage: VDD2 = 7.5 V
Load: RL = 5 kΩ, CL = 75 pF
Driver part supply voltage: VDD2 = 9.0 V
Load: RL = 40 kΩ, CL = 80 pF
Driver part supply voltage: VDD2 = 9.0 V
