This isn’t technically correct. CRT, LCD, and OLED displays are generally constantly refreshing the image. There are some niche exceptions like memory-in-pixel displays but they are few and far between. eInk displays are very different in this aspect because the display itself acts as a physical memory of the image because its mechanism of creating an image involves physical changes (pigmented particles moving closer or further away from the visible plane).
I just wanted to add this video to your comment because e-ink is so cool and this guy has a bunch of macro shots of the displays that are awesome and you can see the particles in the screen changing colors.
Are you talking about pwm? Most screens don’t refresh if nothing is changing
