Hello Henry,

Thank you for your patience as e2e access was not available for the last few days due to maintenance issues. I reviewed the schematics and noticed that this application is using the extra charge pumps to generate the gate supplies as well for the panel. There is a TI design "Bipolar TFT LCD Supply Using TPS65131-Q1 and Charge Pumps" which was validated as working good and I would suggest to follow that design for generating source and gate supplies. Below is a link to the TI design.

Kind Regards,

Liaqat
