  1. Introduction to Video Wall Technology For the sake of this definition, Video Wall, Data Wall, and Media Wall will all be referred to as a Video Wall. The scope of this page is to introduce the concept and technology for some types of video walls. A Smd video wall is any large electronic display of an image or images being displayed in a presentation format. Typically multiple display devices are tiled together as close as possible in a matrix to create a single logical screen (The Video Wall). Then with special Video Processor devices, an image is scaled across the logical screen or multiple images are spread out over the logical screen or a combination of both in the case of picture in picture. This is all without respect for the individual display devices physical boundaries. The individual display devices can be anything from the smallest (4" diagonal) direct view LCD screens to very large (120" diagonal) front or rear projection devices depending on the ultimate size of video wall being created by the matrix. LED walls use individual discrete light emitting diodes from .5mm each to create each pixel. For a discussion on Direct View LCD/Plasma displays and Video Wall Cubes, scroll to the bottom of this page to "Which Display Device to Use?. The rest of this article will focus on building Best Smd video walls in Pakistan with matrices of complete display devices and not LED technology. The reason for creating large logical displays in this fashion is that you can assemble a single logical display area that is brighter, larger, higher resolution and has inherent redundancy unlike any other method of image display. The human brain has the ability through your eyes to see and comprehend multiple changing messages through images all happening in real time by scanning each image in some rotation. It is for this reason that video walls can uniquely present many pieces of information to multiple people at the same time in the same place.
