A virtual retinal display (VRD), also known as a retinal scan display (RSD), is a new display technology that draws a raster display (like a television) directly onto the retina of the eye. The user sees what appears to be a conventional display floating in space in front of them. In the past similar systems have been made by projecting a defocused image directly in front of the user's eye on a small screen, normally in the form of large sunglasses. The user focused their eyes on the background, where the screen appeared to be floating. The d ....etc

RT stands for cathode ray tube, the common picture tube used in TV sets for decades and still the most common display type today. Newer display types like Plasma and LCD work differently and aren't as large or heavy as the CRT, but the picture isn't necessarily any better.

CRT produces its pictures from a ray of electrons emanating from a cathode in the neck of a picture tube. The ray strikes the inner face of the picture tube, which is coated with lines of phosphor that light up when struck by the electron beam. The scan line offers resolut ....etc

The electrowetting behavior of mercury and other liquids on variably charged surfaces was probably first explained by Lipmann in 1875 and was certainly observed much earlier. Froumkin used surface charge to change the shape of water drops in 1936. The term electrowetting was first introduced in 1981 to describe an effect proposed for designing a new type of display device (G. Beni and S. Hackwood, Appl. Phys. Lett. 38, 4, pp.207-209, 1981]. Digital microfluidic manipulation of chemical & biological fluids was first investigated by J. Brown in ....etc

A 3D display is any display device capable of conveying three-dimensional images to the viewer. There are many types of 3D displays: stereoscopic 3D displays show a different image to each eye; autostereoscopic 3D displays do this without the need for any special glasses or other head gear; holographic 3D displays reproduce a light field which is identical to that which emanated from the original scene (for the technology, see Computer Generated Holography). In addition there are volumetric displays, where some physical mechanism is used to dis ....etc

INTRODUCTION
Various types of displays have become common in the every day life. The displays are used in televisions, computers etc. They also have wide use in laboratories and in medical applications. The displays are those devices by which we can view moving objects. The displays are manufactured depending upon their application.

One of the hottest markets driving physics research is the demand for a perfect visual display. People want, for example, large, thin, lightweight screens for high-definition TV and outside displays and very hi ....etc

VIRTUAL RETINAL DISPLAY

The technologies of virtual reality (VR) and augmented reality (AR) are the new paradigm for visual interaction with graphical environments. The features of VR are interactivity and immersion. To achieve these features, a visual display that is high resolution and wide field of view is necessary. For AR a visual display that allows ready viewing of the real world, with superimposition of the computer graphics is necessary. Current display technologies require compromises that prevent full implementation of VR and AR. ....etc

With the imaging appliance revolution underway, the need for more advanced handheld devices that will combine the attributes of a computer, PDA, and cell phone is increasing and the flat-panel mobile display industry is searching for a display technology that will revolutionize the industry. The need for new lightweight, low-power, wide viewing angled displays has pushed the industry to revisit the current flat-panel digital display technology used for mobile applications. Struggling to meet the needs of demanding applications such as e-books, ....etc

The term electrowetting was first introduced in 1981 to describe an effect proposed for designing a new type of display device . The electrowetting effect was originally defined as the change in solid electrolyte contact angle due to an applied potential difference between the solid and the electrolyte. Electrowetting is akin to but distinct from electrocapillarity. In the past 25 years or so a large number of devices based on electrowetting have been devised. In particular, ....etc
