Some Chinese display manufacturers are dumping lots of small, easy to use, postage stamp sized monochrome blue-white OLED at ~$1.5 apiece from 1 unit with free shipping, which had made it a viable replacement for 7-segments, couple power LEDs, even decorative logo displays, for small scale productions. It's not the case at all for real mass produced products, but not everyone is delivering thousands of units per month to Walmart.

I personally don't necessarily support "just go graphical" sentiment, but such local minima do exist.
