3-D Displays: Its Time is Coming?
1993: Apple Newton Message Pad~300k units sold - discontinued

3-D Displays – Why Previous Attempts Fell Short?Glasses, Content, Gimmicky, Eye Strain, More Hassle than Worth…
We perceive 3-D through several cross-linked cues –getting all of them right is critical to “natural” 3-D
So far, binocular disparity (i.e. stereoscopy) has been the focus of 3-D solutions
External use
Human Eyes Use Multiple Cues to “See” 3-DAvoiding cue conflicts and providing natural and consistent stereo, parallax and focus cues Winner !!
1. Binocular Disparity
2. Convergence
MONOCULAR CUES
1. Retinal Blur
2. Accommodation/Focus
4. Others: Shading, Color, Texture, Size, Perspective, Gradient, Lighting…

Candidates for “Natural” 3-D
HolographyDiffraction grating waveguides for holographic construction
Foveated RenderingEye tracking to render fovea image in high resolution, rest blurred
Light Field DisplaysMulti-focal planes (time multiplexing)
Multi views (spatial multiplexing)
Lends itself to large area displays
External use14
Backplane Yield Challenge Example: Particles
Smaller TFTs have more (& smaller) killer particles
OLED TFT active area larger than LCD increasing chance of “killer particle”
Increasing resolution increases # transistors/area requires smaller TFT increases # of killer particles

Displays are the window to the “information universe” and better displays are constantly in demand
Many display technology inflections need materials engineering innovation & “semiconductor” methodologies
The industry is creating the building blocks to enable roll-to-roll manufacturing of more complex flexible devices and applications
