The present invention is a 'LED based Pepper's Ghost Technique (like Holographic Display) realised by deploying LED video display screens for providing 3D viewing experience of Pepper's Ghost virtual images with rich colour, contrast and clarity to cater to various indoor and outdoor applications. While True colour 'Real LED TVs ' can be deployed for showing the image to be displayed in the holographic form in outdoor situations , LCD/Plasma TVs can also be used for same purpose in indoor applications. Live or a stored holographic content is fed from a central server to a Holographic Display (LED Video Display Screen). In addition, the same content will be automatically converted and fed to a host of other heterogeneous terminals like Big LED Video Walls, Plasma TVs, LCD (LED backlit) TVs, LED video display screens etc for a simultaneous display as if it is fed from the original / live in 2D or 3D. The invention eliminates the need for deploying conventional opto-mechanical projection systems, and thus optimizes the space occupied and the operation & maintenance related issues and also avoids the problems associated with Opto-Mechanical projection systems. The Pepper's Ghost images that can be realised with true colour LED video displays are distinctly characterised by the capability to show large, life size images with rich colour, intensity and depth, which can not be obtained with conventional projection systems or with plasma / LED-backlit LCD displays. This capability is essentially because of the modular construction of LED displays, virtually to any size and shape; wide range of pixel pitches & resolutions; and as many as 280 trillion color combinations achieved by 16-bit colour processing technique. Further, the LED displays have an operating life of more than 50,000 hours. Unique features like high brightness, dynamic content management, configurability to customize special applications, wide viewing angle and day light visibility of the True colour LED displays position them superior for deployment in the Pepper's Ghost image applications in comparison with the present projection systems. The application range covers Mass Communications, Education & Training, Entertainment and Advertisements etc for centralised or dispersed viewer communities.
