Hello again,
LG:
Thank you for the photos, i will study them and compare to my display. I am also thinking about taking one completely apart so i can solve this mystery once and for all, regardless if i can get it back together or not.
Miguel:
Thank you for the offer. This one is 24 x 1 line. It uses HD66717 controller. One of the problems is the backlight, the other is that it is HARD WIRED for 8 bit parallel operation, even though that controller is capable of I2C control, and it is impossible to get to the wiring because it is under the COB chip (unless of course you know a work around).
One of the reasons i was trying to get this lit up was because it is hard to see without some light, and i have a few of them so i thought i could use them for various stuff.
What kind of displays to you have on hand, and what color backlight?
I hate to put you through that much trouble though. I do have a display that is backlit and am getting another one, but i like these little displays because they are so narrow. They can fit in a package probably about the size of a cigar or maybe a little bit wider so that means they can be used in a hand held pen-like probe.
