I'm a bit confused trying to reconcile the diagram on page 4 of the datasheet with the diagram on page 5. Please can you tell me if I simply need to connect a 12V supply and leave it at that, or whether I need to take care of controlling the heating power? I presume I can choose to simply not use it? Thanks.

Please can you confirm that being COG does not in itself imply that a display has no current limiting resistors for the backlight? I'm looking at NHD-C12864A1Z-FS(RGB)-FBW-HT1, and it appears to show some in the "Mechanical Drawing" LED circuit, but now I'm not quite sure. Thanks.
