Description

Testing Arduino controlled DIY low cost Parallax 3D Display: two 1.3" low cost 240x240 LCDs are used to create a 3D Display that needs no glasses, and can be easily intefaced with Arduino and similar microcontrollers.The 3D effect is much more intense when seen directly, it is quite difficult to record. I wrote a program in Delphi that reads a stereo photo pair and creates a single bitmap with alternated Left and Right "strips" of customizable width. One screen has backlight and shows the photo. The other has the backlight removed, and is used to show the black /white strips for the parallax effect.Theory of parallax system for 3D displays: https://en.wikipedia.org/wiki/Parallax_barrier . Inspiration from http://spritesmods.com/?art=3dmonitor&page=1.

  • Testing the first working prototype

    This is the first working prototype. More info will be added soon. The effect is much better in person. There are some parts of the video where the recorded effect can still be seen, like the glove of the female boxe fighter that "moves" as the camera shifts.

    A lot of useful info here: http://displayblocks.org/diycompressivedisplays/layered3d/ (including how to align the screens).

    Many stereo photo pairs here: https://urixblog.com/en/category/species-en/humans-en/

Hi! The effect that is normally achieved by the lenticular lens, here is replicated by the parallax barrier (that is, the front Lcd without backlight, showing a pattern of alternated white/black lines).

  Are you sure? yes | no

Mike Szczys wrote 09/14/2020 at 21:08 • point

Proof of concept looks pretty good in the video. Are you using some type of a filter or lenticular lens to make sure light from each screen is directed (or blocked) so that each eye only sees light from one screen?

  Are you sure? yes | no
