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.

Pervasive Displays 2.7 inch

Active area: 29 x 22 mm / 264 x 176 px

34 euros per screen, when buying 10-15 pcs.

Pervasive Displays 4.41 inch

Active area: 90 x 67 mm / 400 x 300 px

52.60 euros per screen, when buying 10-15 pcs.

Pervasive Displays 7.4 inch

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.)

LCD

Or use a digital frame.
