Thread: LCD screen powered by MOSFET inverter

Anyway, the mosfet turns the screen on very well and i was curious if anyone had any comments on if this is a good or bad way to power my screen? I currently haven't put an Opus powersupply or computer in, but I know that's another option to power my screen.

thanks for any input!

I use the " egg" for the power of the Lilliput, and' ok, however' I have made 2 changes:
1 - you put a filter on the entrance of the power EMI-RFI by MURATA name BNX002 (you make a searchin of Internet for datasheet) and so' you eliminate every trouble.
2 - you put a relay in miniature, the spool you do h activate from the +12 of the MB, to the contact C you put the +12 Vbatt direct, and on the contact NA connects the power of the Lilliput.
This way' and' the MB that " turns on" the Lilliput.
