Light Leaks
Using standard projectors, an array of mirror balls, a lot of math, and a map of the space, Kyle McDonald and Jonas Jongejan created this piece to create spatialized visuals.
Wedge Display
The CamFPD Wedge Display - No updates or news since 2004. Seems to be a similar principle to waveguide displays used for AR headsets by "projecting" light on a flat plane.
Lickable Display
A researcher has combined a traditional display with an aerosol dispenser to spray a screen with different flavors that can be licked by a user to be able to taste what is on screen. The project is called Taste the TV by researcher Homei Miyashita
Liquavista Electrowetting Displays
These displays promised an alternative to E-Ink but with a faster refresh rate but never made it to market. You can read more about them here.
Deconstructed LCD
Colloidal Bubble Display
This experiment involves using a special coilloidal solution and an ultrasonic speaker that can be used to "tune" the transparency and reflectiveness of a bubble when light is projected on it.
Stacked microLED
Most pixels are arranged as red, green, and blue pixels arranged horizontally side by side. In 2023, MIT unveiled a stacked vertical pixel arrangement that allows them to be stacked on top of eachother for greater horizontal density, an important component of higher resolution headset displays.

Phases by AV&C
This piece really strays between lighting element and display for me, but I think it's worth mentioning. It uses an array of mirrors and lights to create controlled reflections around the space - Phases by Vincent Houze and AV&C
Optical Trap Display
SImilar to some of the other listed experiments like Aerial Burton, Femto Fairies and acoustic levitation, an optical trap display uses a complex optical stack to essentially illuminate a particle in air. This has been researched by Daniel Smalley at Brigham Young University. More info at these links: Link 1 Link 2 (Whitepaper) Video
Robotics and Displays
There are a few examples out there of displays on robot arms and moving displays. I'd say these are a little different from the mechanical displays in the other section since this is about moving whole units of a display versus moving individual pixel elements.
And while the below project from Bot and Dolly is really a projection mapping example, it really needs to be mentioned in this category.
