2. Old School
Here we see examples of the current display
technology…touch screen. Many of us have smart
phones or tablet computer with touch screen
displays. We predict that our touch screen displays
will soon be as “old school” as chalk boards.

3. The Emerging Technology

4. Screen less displays
 Screen less display is the emerging
display technology. In the previous
examples we can see that the user is
able to interact with a three
dimensional image projected into thin
air. This technology seems a fantasy
but is quite real.

5. Introduction
 One of the more frustrating aspects of modern
communications technology is that, as devices
have miniaturized, they have become more difficult
to interact with – no one would type out a novel on
a smart phone, for example.
 The lack of space on screen based displays
provides a clear opportunity for screen less
displays to fill the gap.
 Full sized keyboards can already be projected onto
a surface for users to interact with, without concern
over whether it will fit into their pocket.

6. Movie Depiction
This is a familiar
image.
This picture is taken
from the famous
movie “Avatar”.
Screen less display
technology has
been depicted in
movies for
decades.

7. Types of Displays
 There are three main types of screen less displays
that I will share in the next presentation.
1. Visual Image- screen less display includes any
image that the eye can perceive.
2. Retinal Projection- these systems are a class of
screen less displays in which images are projected
directly onto the retina.
3. Synaptic Interface/Brain Computer Interface- this
screen less video does not use light at all. Visual
information completely bypasses the eye and is
transmitted directly to the brain.

8. Advantages and Disadvantages
 ADVANTAGES:
 Low power requirements
 Higher resolution images
 Greater portability.
 Wider angle of view
 More accurate color
 Greater brightness and better contrast
 Ability to present 3D images
 Ability to present far-point images
 Lower costs
 DISADVANTAGES:
 The principle disadvantage is that Virtual retinal display (VRD) is not yet
available in the significant number.
 Prototypes and special experimental models are now being built, but their
cost per unit is high.
 The VRD technology is still under progress and development.

9. Predictions
 Screen less display technology is likely to affect
1. Lighting and projection technologies
2. Software development/design
3. Lifestyles of the visually impaired
4. Career opportunities for the visually impaired
 The most profound effect will come from the development of the
synaptic interface technology.
 This technology will allow people who are visually impaired to see.
Imagine a visually impaired person gaining the freedom to drive
again!
 This will also remove occupational limitations of the visually
impaired.

10. Experts Say....
 Futurist Reto Meier predicts that 10 years from now we will be
able to get transparent LCD patches that will adhere to our
eyeglasses and 20 years from now we’ll have contact lenses
that project images directly onto our retinas and that we will
be able to interface with computers through mind control.
 We don’t know about that but the screen less display
technologies are sure to affect related technologies related to
lighting and projection.
 Software will have to be designed to work with the new
display technology and output will have to be geared to
brighter, more contrasted colors to aid visibility.
