The document discusses screenless display technology, which aims to display information directly onto the retina without the need for a screen. It describes three main types: visual image displays like holograms and heads-up displays; virtual retinal displays, which project images directly onto the retina; and synaptic interfaces that transmit visual information straight to the brain. The technology offers advantages like lower power use and higher resolution but development of prototypes remains costly.

SCREENLESS DISPLAY
- 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. Projector Projected Image 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.
