Display Differences

Hello, there are differences between these two displays?
https://www.newhavendisplay.com/specs/NHD-12864WG-BTMI-VN.pdf This is my display.
https://www.sparkfun.com/datasheets/LCD/GDM12864H.pdf
this is the display of the schematic.
I'm building a circuit found on the internet, and I have a problem: When changing the screen, there is a display issue..
This is the first screen: https://img199.imageshack.us/my.php?image=85302001.jpg
This is the second (change after 1-2 seconds automatically): https://img199.imageshack.us/my.php?image=18223814.jpg
Ps: sorry for my bad english ._.

Re: Display Differences

Hi,

Looking at the spec sheets they appear to be identical Ks0108 controllers with identical pin outs.

The fact you get a correct image on the first screen would mean one of two things to me, either you have a poor connection on your breadboard or there is a fault with the program code.

Are you able to test the micro and glcd with some other code ? - don't know what you are using hardware or software ?
