testing lcd?

quick question

I found an old lcd and was wondering if I could test to see if it still works, without using my arduino (cause its fried :’( )… it has a backlight, if that affects your answer

First step is to identify the LCD driver chip and find out if it’s an HD44780 compatible. I don’t think you’ll get very far in testing without some sort of microcontroller to drive it.

not even to see a flicker? alright… i guess im stuck for some time then

Believe it or not, it can actually be done. This 12 year old article explains how!

Aha! You’re right! I’d forgotten about that old EPE article.
