3. Abstract
• Screenless display is an innovative display technology that projects visual information
directly onto the user's environment without the need for a physical screen.
•This technology leverages various methods, such as holography, light field displays, and
retinal
projection, to create immersive and interactive visual experiences.
•Screenless displays can be used in a range of applications, from augmented reality and
virtual
reality systems to heads- up displays in automotive and aerospace industries.
•By eliminating the need for traditional screens, screenless displays offer advantages in terms
of
space efficiency, adaptability to different surfaces, and enhanced user engagement.

4. Introduction
• Screenless display technology transmits and displays visual information without traditional
screens or projectors.
• Key principles include holograms, virtual retinal displays, and synaptic interfaces for
immersive
viewing experiences.
• Holograms provide three-dimensional representations of data, enhancing perception and
interaction.
• Virtual retinal display projects images directly onto the retina, creating a more direct and
engaging viewing experience.
• Synaptic interface transmits visual information directly to the brain, potentially revolutionizing
digital content perception.
• Used in various fields, including augmented reality, virtual reality, mobile devices, and notably
