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.
So cool!
