Limiting Resistor to LCD

[Denis]

HI, I?m using a MD-LCD420, but I?m using 12v power supply. So I need to change the limint resistor. Right?

For 24v the manul suggests a 150(omhs) resistor. So for 12V what resistor should I use. I think it?s  a 57 or 58(omhs). Is it right?

Thanks.

You can use a 68 Ohm 3 W resistor to use the LCD420 backlight at 12V.
