Introduction to Virtual Retina Display Presentation:
Virtual Retina Display (VRD) is an alternative to conventional bulky power consuming video display units. In VRD’s video is focused on minuscule image right on retina. Color is produced using LED triads of Red, Green, and Blue (RGB) by mixing in required proportion. Video signal is intensity modulated when light gets scanned by retina. Collimating optics is used in raster patterns when scanning is performed directly by retina.
We can use VRD systems in military applications for helmet mounted displays. In medical field it can be used for complex operations. It can also be used in cameras for better display screen which consumes less power that the conventional liquid crystal on silicon and organic LED displays.
Key features of VRD are as follows:
Weight to Size ration: – since there is absence of intermediate screen and all parts being small and light weight VRD is portable and can be used in hand held and head mounted devices.
Power consumption: – VRD consumes power in mille watts since scanner is a resonate device with high figure of merit. Entire light enters pupil in VRD because of employing small aperture. This allows power efficiency.
Resolution and brightness: – With a million pixels and high grade scanners are having an ability to scan over 1000 lines per frame almost nearing HDTV. Even in day light SLD source provide brightness to the level of see through mode.
Stereoscopic display: – in order to provide natural vision both eyes are addressed separately using stereoscopic display.
