Screenless Displays

The screenless display would  works on the basis of pulse rate, skin temperature, breathing, expression, body movement and many other physiological behavior. Screenless display utilize the transmission of information without the requirement of actually having the physical screen. As we have seen in the Movie 'Avengers' emerging technology has the new advantage.Such as presenting 3D Images, far point images and has a kind of large angle of view . It also has far better privacy and would bring revolution.

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. Several patents are still working on this new emerging technology which can change the whole spectacular view of the screenless displays.

Screenless display technology has the main aim of displaying or transmitting the information without any help of the screen or the projector. Screenless displays have become a new range of development for the next generation. Screenless videos describe systems for transmitting visual information from a video source without the use of the screen.

Origin

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.

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 just as the hearing impaired are able to hear through cochlear implants.

First Screen-less Display

The first screen-less display that needs mentioning is Google Glass. Google Glass sits on the face like a pair of glasses, and on one eye it has block of glass that allows you to see augmented reality. Imagescan be displayed right in front of the eye, as well as text and information about objects and places that are in front of you. This technology is only in its early stages, but definitely shows that screen-less displays will become a natural form of media consumption in the future.

 The Sixth Sense Technology

It is wearable gestural interface that augments the physical world around us with digital information and lets us use natural hand gestures to interact with that information. In this technology user is able to interface with a three dimensional image projected into thin air. Imagine your desktop floating in the space before your eyes waiting for your interaction.

3D Display Projection Technology

With the large influx of new displays into the market boasting ‘3D supp’, we will look at the two main techniques being used today, those being active shutter and passive polarization technologies. We will also discuss the trends in desktop displays from a 3D point of view as well as looking at the other aspects being developed to support 3D, such as panel technology.

Types of Displays

Screenless computing systems can be divided into three groups.

Visual Image

Retinal Projection

Synaptic interface
