To go much above 20W the mechanical, thermal, and RF layout
is a significant effort..? Also an amp that is fairly flat and has a
reasonable IMD might be worth it and also resilient (blast proof).
Also above 20W diode switching may require revisit for better
devices.? ?Higher power means more space for more robust LPFs.
I just put an oled screen on a project at 11.3 inches and less
than .5A at 5V.? Not a touch screen but usually they do not
require more power for that subcircuit.
