Screenless Displays
                     SCREENLESS 
DISPLAYS
THE EMERGING COMPUTER 
TECHNOLOGY
What is Screenless Display?
• Screenless display is an interactive projection technology 
developed to solve the problems related to the device 
miniaturization of the modern communication 
technologies. 
• The lack of space on screen based displays provides an 
opportunity for the development of screenless displays.

Types of Screenless Display
• Screenless display technology is divided into three main 
categories:
• Visual Image Display
• Retinal Display
• Synaptic Interface

Visual Image Display
• The visual image is a type of screenless display, which 
recognizes any type of image or thing with the help of 
the human eye.The following are few examples of the 
visual image display: holographic display, virtual reality 
goggles, heads up display, etc.

Working Principle of Visual Image 
Display
• The working principle of this display states that the light 
gets reflected by the intermediate object before reaching 
the retina or the eye. The intermediate object can be a 
hologram, Liquid Crystal Displays (LCD)s or even 
windows.

Advantage of Visual Image 
Display
• The main advantage of visual image displays is creating 
and manipulating the images upto any size. 
• In this category of displays, multiple bitmaps can be 
composited together in the object mode and, in the 
image mode, manipulation takes place.

Retinal Display
• The second category of advancement in display system, 
retinal display as the name itself indicates the display of 
image directly onto the retina. 
• Instead of using some intermediate object for light 
reflection to project the images, this display directly 
projects the image onto the retina.

Synaptic Interface
• The third category, synaptic interface means sending 
information directly to the human brain without using 
any light. 
• This technology is already tested on humans and most of 
the companies started using this technology for effective 
communication, education, business and security 
system.

Successfully Tested
• This technology was successfully developed by sampling 
the video signals from horse crab eyes through their 
nerves, and the other video signals are sampled from 
the electronic cameras into the brains of creatures.

Interaction between the human 
brain and external devices
• The brain computer interface allows direct interaction 
between the human brain and external devices such as 
computer.
• This category can also be known by different names 
such as human machine interface, synthetic telepathy 
interface, mind machine interface and direct neural 
interface.
