OMG!!! Basic Ohm's Law  ;D ;D ;D

How I didn't think it before? I feel like a fool  :-[

Thank you very very much  ;)

I guess you want to say 1K2 ohm resistor (brown - red - red - gold/silver)

I'll try it if you confirm me that issue.

Thank you very much for your answer.

I've been looking at the datasheet of the NHD-24064WG-AYYH-V display and the backlight current (660mA) seems to be very high compared with other similar displays (about 100mA).

I want to use a voltage regulator to supply 4.2V but I can't find one who can handle 660mA that needs the display.

It's correct the data of 660mA shown at the NHD-24064WG-AYYH-V datasheet?

If yes, It's possible to connect the backlight display directly to a 5V Power supply?

Sorry for my poor english. I hope you can understand my doubt.

Thanks in advance for your help.
