GLK19264-7T-1U datasheet errata ?

I think that there's an errata in the DS of the GLK19264-7T-1U device.
In the Description column of the "Set Drawing Color" command, the following text appears:
Drawing color (0: White, 1-255:
Black).
But it actually should be:
Drawing color (1-255: White, 0:
Black).
That's verified.
Please correct this in your datasheet.
Thank you.
Regards,
Dor.

Unfortunately, depending on the display, both could correct. The most common display we sell is a yellow/green display, and when you draw, the 1-255 is actually black, while 0 allows the background colour through.
An inverse display, well, inverses this situation.
In short, nobody has really complained about it before. Sorry to say there will be no errata.

Oh, so how someone can distinguish if the data that he reads refers to his display?

The pictures on our website will clearly distinguish the colors for on or off, which will help you in picking which colour to purchase. The logic levels to each pixel are really irrelevant to the end result, and if anything the wording could be changed to:
0: Background
1-255: Foreground
But we felt that was unclear as well. In the end choosing black/white as we did seemed to be the less of all evils. Most of our customers will simply pick an inverse blue display (picked at random to illustrate) knowing that the text is white on a blue background, assume that 1-255 is white and 0 would be blue, and they would be correct.
