HP Calculator Highlights since the 1980

I looked into OLED display types early on.

Something like the attached display is almost ideal and it may even fit inside a stripped Classic case, being about 70mm wide. The lower custom 5 x 5 digit size is about 0.5mm higher than the original LED displays. On average it would draw about 20mA at 50% duty cycle which is not too bad.

The downside, is the cost per display is about 5 times that of a 15 digit 5mm high LED display and a whole line would be wasted. I haven't been able to find a single line display similar to this.
