Old SchoolHere 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.

The Emerging Technology

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.

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.

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.

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.

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.

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.

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.
