LCD zoetrope tests
A test using a circular array of smartphones - to find out if zoetropic motion is possible with LCD screens. Findings:
- It works
- The limited viewing angle doesn't seem to be a problem
- When viewed in the dark the screens seem to 'float' mid-circle
- The screens reflect into each other, better use non-or-less-reflective ones
- In a dark environment the screens cast beams of light on the surroundings
- As with a regular zoetrope, images get slightly squished horizontally
- This test should be repeated with just iPhones, set on the same brightness, and using thinner slits.
Shadowplay tests
Makeshift setup:
Displays for a possible display-based zoetrope
E-paper
E-paper would be great, as it's thin, viewable from a broad angle, has a high contrast and a nice texture. Pervasive Displays manufacture e-paper displays, one of their offices is located in Soest, The Netherlands. They don't sell it, sadly. The cheapest/nearest reseller I found is Ineltek, in Heidenheim, Germany.
Active area: 29 x 22 mm / 264 x 176 px
34 euros per screen, when buying 10-15 pcs.
Active area: 90 x 67 mm / 400 x 300 px
52.60 euros per screen, when buying 10-15 pcs.
Active area: 100 x 162 mm / 480 x 800 px
119,75 euros per screen, when buying 10-15 pcs.
Taking apart a broken e-reader to see if it's possible to do something with the screen.
Running electricity through the screen connection randomly, it didn't work as the voltage was too low.
A recent discussion about e-paper on the Arduino forums.
Perhaps an alternative would be to buy a bunch of cheap e-readers. (These are sold out everywhere.)
