MaG2k Posted August 7, 2013 Report Share Posted August 7, 2013 (edited) Hey @ all, i am searching for a green negative display with 40x2 characters for my second SEQ V4. I found one at mouser that fit my parameters but i didn't found if the NT3881 controller of this optrex C-51850NFQJ-LG-ACN display is compatible to the HD44780 standard display driver. http://de.mouser.com/ProductDetail/Optrex/C-51850NFQJ-LG-ACN/?qs=%2fha2pyFadugV%252b8G4BKyno1j%252bOJ502VJJ3WoTXbvzA6fbvRZRg9MkNQ%3d%3d Does anyone of you used that display allready or isn't it working with this application (SEQ V4)? Thanx for your help! Regards MaG2k Edited August 8, 2013 by MaG2k Quote Link to comment Share on other sites More sharing options...
Altitude Posted August 8, 2013 Report Share Posted August 8, 2013 (edited) Those are fine, I use them all the time, I actually used those exact green ones on my SEQ.. Just make sure when shopping at Mouser. you go by the part#, not the picture when picking one out. The one in the link is a good example, the pic shows a white on black but the description is for a green one. I always check the Kyocera site, they are always correct there.. . Find my thread about improving the contrast on those, I had a really hard time getting them to look good (the backlight was shining through and they looked blotchy) so I made some changes to the circuit which improved things a lot Edited August 8, 2013 by Altitude Quote Link to comment Share on other sites More sharing options...
MaG2k Posted August 9, 2013 Author Report Share Posted August 9, 2013 (edited) Thanx for your help. Yes i allready realised that the picture on the Mouser website doesn' match the parameters. Can you post / link your thread about improving contrast here? Thanx Regards MaG2k Edited August 9, 2013 by MaG2k Quote Link to comment Share on other sites More sharing options...
