| latest screenless display |
This field came into progress during the year 2013 by the arrival of products like holographic videos, virtual reality headsets, retinal displays, mobiles for elderly, eye tap etc. At present, we can say that only part of the Screenless Display Technology is brought up which means that more advancement is necessary for a boost in the technology. Lack of space is one of major problem faced by screen displays. This problem will surely provide a pathway for screenless display.
What is Screenless Display?
Screenless Display was an excellent thought that came into many experts inorder to solve the major problems related to the device miniaturization. Lower space screen displays have made the need of screenless displays more than ever. Screenless, as the word suggests clearly means ‘no screen’. So, Screenless Displays can be defined as a display which helps to display and even transmit any information without the aid of screens.When will screenless displays be fully available? This question is not yet answerable since many developments are under stage only. Since the displays are capable of projecting 3D images to the space, many disadvantages of 2D and screen based displays can be avoided. Displaying feature of it can be thought of as a projector without a movie. Using this excellent technology, we can even make our smart phone a TV. The countdown for the first screenless display has started now currently from the month of May 2014 onwards. Screenless Display currently uses Interactive Projection technology with visual display and 3D Projection Technology.
Screenless Display Types:
Screenless Display can be grouped into three main categories. They include Visual Image, Retinal Display and Synaptic Interface.Visual Image Screenless Display:
Visual Image is a type of screenless display were the eye or the retina can recognize any screenless image. Holographic display, Virtual Reality Goggles and Heads Up Display are some present visual image screenless display examples. The display works on the principle that; light gets reflected by the intermediate object before reaching the retina. The intermediate object can be holograms, windows, or even LCDs.Holographic messages that became popular through the ‘Star War Film’ are now becoming a truthful reality. Holographic Displays allow the display of three dimensional images by using simple components like Helium – Neon Laser, a Lens, an object, mirror and a holographic film. The laser beam used will initially create a plasma environment. When the laser and object beams coincides, a 3D image will be projected. The projected image will appear to be floating in air. Presently, MIT’s Media Lab reported a holographic color video display (inexpensive) with the resolution of TV. Latest fiction movies the ‘Iron Man’ and ‘Avengers’ have shown this technology in more advanced form. This advancement can be expected in the coming future.

Virtual Reality Goggles (VRG) is an eyewear display device. Wearer can view and interact with a series of computer generated images. Consist display screens in front of face. Images can be projected with sound and video, allowing it more popular for entertainment applications. Presence of polarized lenses is the major feature of VRG. These lenses will show two images, one per each eye and the brain combines them to form a three dimensional image. They show an illusion of depth. Many of these goggles are accompanied by head tracking systems connected to a computer, thereby adjusting images seen by the wearer as they move around.
‘World of Warcraft’, ‘Quake2’ are some popular games that can be played using VRG. The famous ‘Oculus Rift ‘and the recent ‘Google’s Cardboard Virtual Reality Goggles’ is an evidence that VRG is on its way. Now many DIY VRG are coming out since it requires only components like a smartphone, two lenses, a rigid paper or cardboard and some tape. ‘Sony Headman’ a virtual reality headset by ‘Sony ‘is also gaining popularity now.

In January 2014, Glyph Company had raised a
sum via KickStarter with the aim of bringing personal gaming and cinema
device using retinal display. Eye Tap and Bionic Contact Lenses are
some present day examples for retinal displays. Eye Tap, is a display
device that can act as a camera and a monitor. It can be worn on the
eye. Generally a beam splitter is the major component of the eye tap.
Now the eye taps are replaced by the smart Google Glasses.

Bionic lenses use
components like electric circuit with red light-emitting diodes, a
sensor and a micro size silicon chip for visual display. Controlling the
display intensity and all functions by voice is the major feature.
Infrared rays help transfer of information within the lenses. Many
research and developments are taking place with these lenses.
Screenless Display Advantages & Disadvantages
The products belonging to this emerging technology bring out many advantages compared to the existing products with the old technology. While taking the images into consideration, the present screenless displays have the ability to present 3D images, far point images and an image with higher resolution one. Good brightness and contrast and large angle of view are the other essential advantages. With the increasing use of the screenless products, we can expect a decrease in the cost also in the coming future. Lower power consumption, light weight, and providing better privacy are some essential advantages achieved in all the smart screenless display products. The screenless displays will boost up the field of entertainment at a great stage.Disadvantages faced now are basically the higher cost and limited availability of the screenless display products. Most of the technologies required for the outward of screenless display are in development stage only. Many problems related to eye sight can arise since the products require close interaction with the eye.
This the latest technology introduced to us .
I Like to add one more important thing here, The screenless display market is expected to reach more than USD 6000 Million by 2026 at a CAGR of 31.45% in given forecast period.
