“SCREENLESS DISPLAY – THE EMERGING COMPUTER TECHNOLOGY”

1. SCREENLESS DISPLAY
Presented by:
Muhammad Mahad Mumtaz

2. Introduction
 Screenless display technology has the main aim of displaying
(or) transmitting the information without any help of the
screen (or) the projector.
 It displays the information directly into the retina of eye rather
than displaying through screen like LCD monitor, Touch
Screen Display, etc.
 It is one of the TOP 10 emerging technologies in IT field.
 We will be using Screenless display technology during 2020’s.

3. Types of Screenless Displays
3 Types of
Screenless
Display
Visual
Image
Virtual
retinal
display
Synaptic
Interface

4. Visual Image
 Visual Image screen less display includes any screen less
image that the eye can perceive or see.
 The eye or the retina can recognize any screen less image.
 The intermediate object can be holograms, windows, or even
LCDs.

5. Examples of visual display
 Holographic display
 Virtual reality goggles
 Heads up display

6. Products of Visual Screen
DISPLAIR Air Touch System.

7. Virtual keyboard
 On the right is the image
of Screen less touch screens
mini projector which puts a
10 inch touch screen on any
flat surface and on below it is bluetooth laser virtual keyboard.
 This is the future of technology,This technology is also
considered for future I phones, in which the keypad is
projected on the table adjacent to the surface where the
phone is kept.

8. Virtual retinal display
 They are screen less displays in which images are projected
directly onto the retina of eye.
 The user sees what appears to be a conventional display
floating in space in front of them.

9. VIRTUAL RETINAL DISPLAY
 In retinal projection, the light does not have to be reflected
off of an object. The light is projected directly onto the retina
to form an
image.

10. Examples
 Google Glass:
 Eye tap

11. SYNAPTIC INTERFACE
 Visual information completely bypasses the eye and is
Transmitted directly to the brain. While such systems have yet
to be implemented in humans.
 Brain-computer Interfaces - direct communication between
the brain and the external device.

12. Camera sends images to
electrode implant

13. APPLICATIONS
Development of mobile phones
Screen less laptop
Holographic projection
Principle - implemented in the emerging of the new
screen less TV’s.

14. ADVANTAGES
Low power requirements
Higher resolution images
More accurate color
Wider angle of view
Ability to present 3D images

15. DISADVANTAGES
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.

16. Conclusion
The future technologies makes our life even better
for the development of mankind in all aspects of life.
 We should effectively apply these technologies in
reasonable situations and make life easier.
 Physically and Mentally challenged people also have
to be equipped with latest technologies, to enable
them to live a peaceful life.
