replacing it for lower-cost users with seven-segment and/or discrete LEDs?
I was surprised recently when I was designing a little remote monitor and thought it would be nice for it to have a local display on the device. Originally I thought a 7 segment display like what might have been in older calculators would give a nice retro look and be a simple solution. To my amazement 7 segment displays cost more than modern displays. Plus you had to deal with the software multiplexing and the I/o pins needed to do that.?
I finally settled on a small OLED graphics display for just over three of dollars (there are some for as low as $1.50). Even with larger displays, the TFT LCD and OLED displays are mass produced while the 7 segment LED displays seem to be a specially item. The former seem to still be the better bargain. It may have been that I just did not find a low cost supplier for the 7 segment displays, but I did do a reasonable search.
