These displays can be purchased either in monochrome or color and use very little power.

They seem to be the way of the future for generic displays.

I've looked into these for the MultiCalc. In small quantities the cost can be up to 5 times that of LED displays.

I have found that the 100 x 16 pixel RED OLED will just work for the display requirements for all the emulated models. Power requirements are also similar.

For the ones I have seen, the active display width is similar at 60mm, however the overall module width is around 80mm. Obviously for manufacturing purposes they seem to use generic module housings for different size displays. If they created a smaller modules closer to actual the size of these display types then, cost aside, they could be ideal.
