Screenless Display PPT Presentation
- 1. Technical Seminar on Screenless Display By Sai Mohit Talasila 15P81A0553
- 2. Introduction How many of you have watched the Iron Man Movie? The protagonist uses a screenless display to perform operations. It looks like it's some out-of-the-world graphics, right? It's what called “Screenless Display” The screenless display technology is used to transfer or display information without using a physical screen.
- 3. Introduction • Screenless display is the present evolving technology in the field of the computer-enhanced technologies. • It is going to be the one of the greatest technological development in the coming future years. • Development work still going on this new emerging technology which can change the whole spectacular view of the screenless displays.
- 4. Technical Background • First screenless display is Google Glass sits on the face like a pair of glasses, and on one eye it has a block of glass that allows you to see augmented reality. • Images can be displayed right in front of your eye, as well as text and information about objects and places that are in front of you.
- 5. Technical Background • Virtual Retinal Display (VRD), a screenless display technology allowing the image directly to be projected on to the retina. In VRD, no real image is produced. It just beams the image to our eye balls directly. The user will feel that the display is floating in the space in front of him.
- 6. Description • VRD uses a photon source generating a coherent beam of light. Laser Diode like coherent source will help the VRD to give a diffraction limited spot on retina. Followed by Intensity Modulation of light beam is done generally to match the intensity of the image. Then, Beam Scanning is done to keep the image pixels properly on the retina.
- 7. Synaptic Interface • Synaptic Interfaces(another screenless display technology) does not use light at all and the visual image is directly given to the brain. The technology is in the advancement mode and it is now been tested on humans too.
- 8. Virtual Reality Googles • Virtual Reality Goggles (VRG) is an eyewear display device. Wearer feels like he/she is interacting with a series of computer generated images. Consist display screens in front of face. These lenses will show two images, one per each eye and the brain combines them to form a three dimensional image.
- 9. 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
- 10. Disadvantages • You'll miss enjoying entertainment with your family or friends. As the screenless display technology is designed only to accomodate single user at a time! • You'll miss physical touch of your device as there'll be no screen. • It'll be a hard time to convince users to switch from traditional devices(with screen) to this screenless-display technology • Screenless display is costlier than on-screen technology
- 11. Real Time Applications • Screenless displays are used mainly in medical holography for medical imaging applications. • They are expected to find applications in commercial, consumer, aerospace & defense, and automotive sectors. • They are currently used in holographic displays, head mounted displays, and head-up displays. • The total screenless display market was valued at USD 242.1 Million in 2014 and expected to reach USD 1,242.3 Million by 2020
- 12. Conclusion • The screenless display technology is used to transfer or display information without using a screen. • The advancement in the field of screenless displays would lead to the replacement of touch screen displays by screenless ones in the near future. • In due course of time, hardware component is expected to become economical. • This technology is not developed fully till now and is available in a limited range of products.
