3D Volumetric display proposal
- 2012~ Self-motivated project
Since the StarWars or even before, we have imagined about 3D volumetric display. My idea is how to make it possible.
Simply speaking, the OLED Active Matrix display is a 2D array of LEDs over glass. And it is very easy to make it transparent. (You can see an example here.
It's already cool. I recommend to see it highly. ) My basic idea is stacking this glass slices to make it volumetric display.
However there is one problem that is opaqueness. If there is no opacity control, basically every light will overlap each other, thus making a blurry meaningless image. However the LCDs without color filter is basically a glass which can be transparent or opaque by applying voltage to the liquid crystal. Very simple example of this is a transparent LCD clock.
So my basic idea is combining this two technology. With OLEDs, we make a light emitting part, and with LCD we make a light blocking part. I included a few diagram in the attachment. Please refer it.
