Unfortunately there are only 3 colors: White, Gold, and Inverse White.
So the Alpha Letters have to be white.

That was also my reasoning. The display has such a good contrast that you really don't need backlight. I'll share a video soon to show the display in action.

RE: PX41CX
That’s a valid argument.
Is the contrast still good in low-light conditions? I’ve read somewhere that the SwissMicros DM32-41X-42, which have generally fantastic contrast, are not so good in low-light conditions.

At least, white letters will remain easily readable.

In your opinion, which one do I prefer ?

Having just assembled my PX15C, I can guarantee you will have at least TWO sales of the PX41CX as soon as it goes on the market!

Hello,

I think I will also be placing an order for this. Smile
New, smoother buttons, 4-line display ... what more could you want?

Backlight is off on the old PX41CX.

RE: PX41CX
I don't think the picture is being fair to the HP-41, as it is not being held at the normal viewing angle.  My own HP-41cx's definitely have better contrast than that, but I can make them fade out a little bit like what's in the picture if I tip them to the angle the picture was taken at.

RE: PX41CX
The contrast is indeed impressive.
However, I have now another nitpicking remark: I find the coma and the dot on the display very small! I think that it should be improved.
I also hope that the firmware will be easy to upgrade.

Firmware will be easy to update.

About the fonts... currently the fonts are 24x16 pixels and the coma/dot is 3 pixel wide. Maybe make the fonts 15 pixels wide and the coma/dot 4 pixels wide?

Yes, a slightly reduced font would be better. I think the dot should have at least the same thickness as the lines in the characters.
Also, reducing slightly the height of the font would increase the space between the lines, which is currently very small, and allow a more prominent comma.

What I have just noticed ... Is the display shorter? It doesn't go all the way to the right edge of the cut-out.

RE: PX41CX
I would very much like to be able to protect/backup/restore the memory contents of your hobby calculators, is that anything that might be in the realm of possibilty? Even if it's just for the PX41CX it'd be really nice.

I'll do some tests with a smaller font to see how it looks.

Actually the active area of the new display is taller and a bit wider.
OLD LCD 47.98x15.98mm
NEW LCD 48.50x23.67mm

But it is offset to the left.
