Hello,
I'm having trouble finding any (round) displays that can be curved along a circular shape.
The basic idea is that I want to use Arduino to have a gif or video file play on loop on the display. But I need the screen to curve on the inside of a spherical shape.
If anyone has any suggestions regarding flexible screens that are about as big as a hand (4" to 5"), please let me know.
Thanks in advance.
Good luck finding a screen that is flexible in two dimensions
Make your own with a large number of addressable LEDs.
A flat display, no matter how flexible, can of course never be curved to a sphere.
Some kind of beamer at the centre of the sphere projecting on the inside of it may be a solution, thinking of planetariums where they do just that. Finding one in that small sounds like a major challenge to me.
It's a rather wide spherical shape compared to the size of the screen, say a difference of .35cm in both directions
You can curve a flat sheet to a cylinder, since a cylinder has flat geometry, but a sphere has positive curved geometry (the angles of a triangle on a sphere sum to more than 180 degrees).
You need a rubber display for that!
I need something with a little bit more quality. The curved surface I want to put the screen against is more of a face helmet shape rather than a hard sphere.
