Help,Can ordinary LEDs replace thin-film LEDs?

<< < (3/7) > >>

Phil1977:
Do you really want to solder and place over 140 LEDs there?

If yes, I´d try to find out if you can modify the supply voltages of the high voltage driver ICs to LED compatible levels.

daisizhou:
If placing LEDs is feasible I will proceed with the plan.
I don't know if the electrical performance of EL is compatible if I change it to LED, because I am not familiar with EL components.

Page 104 has the schematic diagram of the display part

thanks

Phil1977:
I can't download the manual (registration required) but as I had a quick look over the datasheet pages, I wonder if it´s possible to reduce "V_pp" to let´s say 5V and connect LEDs to the outputs.

The max current of 0.5mA is not very much, but may be sufficient for a bright display. You could test it with a few wired LEDs that get patched to the headers.

Schematic downloaded. Attached.
