This is aimed at GHI as they are the ones with the information.
In your drawing of the TE35 display there is no details of the area required for the display opening. On LCD drawings, this is normally shown as the Viewing Area (VA) and Active Area (AA).
Without knowing which LCD module you actually use, I can’t simply guess from other similar displays. Made this very small mistake with the 4.3 display I have.
Can you please update the drawing of the LCD to show this veiwing area. Same with the 4.3" LCD.
I need this to work out the exact area for the panel cutout.
