Adafruit has two flexible eINK displays. They have a 2.13 (212x104) version and a 2.9" (296x128) version. Both are monochrome displays and both screens require a driver board. The screen can be bent to around 10mm. It should not be flexed repeatedly, and should not be flexed during refresh. Like most eInk displays, it takes a few seconds to redraw an image and the screen should only be refreshed once or twice a minute. Amazon also lists several flexible eInk & driver board combo kits (affiliate link).
Sparkfun has aa flexible and bendable OLED graphic display. It's a 1.81" grayscale display that can be bent to a 40mm radius. It is a 160x32 4-bit grayscale display and comes with an attached SPI driver board. It can flex during refresh, but it's probably not meant for constant bending and flexing. But the ability to wrap a changing picture around a curved surface opens up all kinds of possibilities. (Also sometimes available on Amazon (Affliate Link))

Imagine the possibilities:
- Hats with a changing logo, or showing "First Down" or displying the final score as you walk out of the stadium.
- Bracelets with a scrolling images or the names of your children or declarations of love.
- Shoes that show your current step count
- Just being shaped and non-flat makes the display eye-catching. Put one up at your next crafts fair or over your POS impulse purchase area.
- Combine two or more for larger shapes.
