I did manage to read the "data sheet" if you can call it that. It was more = hand written notes. Thank you to the previous poster who found that BG Micr= o link. Sadly, the data sheet didn't say anything about the EL Backlight; i= t was all about the LCD unit itself. I did read "requires EL inverter" but = that's all the information i could find. How can i find out what power rati= ng inverter i need?=20 --- Begin Orginal Message --- From: Brian Clewer To: PICLIST@MITVMA.MIT.EDU CC:=20 Date: 7/20/2003 9:51:01 PM >>I recently purchases an LCD display, 16x2, from BG Micro.

If it's EL you'll need to feed it around >100V AC to see it light up. If the back light is LED... you might need a new display... An LED back li= t display needs a current limiting resisor in series with it. The data sheet= should tell you how much current should be fed to it and you should be able= to work out the resistance from there. You need to tell us what the model is, or at least a data sheet to look at. Without that, we can't really say= .
