Before knowing about the use of LED video walls and modules, let talk about what they actually are. LED wall displays are flat wall panel display that uses an array of light emitting diodes as pixels for video display. A video wall is made up of many displays that work together in a cohesive manner to display the desired content. The video walls are created by connecting individual LED video wall panels together, stacking them to create a composite image like that from the LCD wall. This display is typically very thin bezels and is packed very tightly to minimize the gap in between the complete display area. It's LED wall technology is becoming immensely popular due to its ability to deliver seamless images with a scalability to any size or shape with the optimum characteristics that make the video wall content look astonishing from any and every angle. Due to the LED technology used in the video walls the display is capable of delivering very high tech, sharp and bright image payoffs. Instead of relying on backlit images, LED's produce their own through the video wall technology. The LED video walls are a win win as they don't require a backlight and produces colored light on their own with voltage. This is what makes them brighter and due to the absence of any filament they are also environment friendly and energy efficient and don't end up burning out or becoming hot. Another reason of LED video walls being so trending is the video wall display screen support. This high tech digital signage is great for engaging customers by providing a world class visual experience of custom video, images and texts based on the time of day, business goal, location and even an individual customer's preferences. The LED video walls are also known for its pixel density with a great resolution that continues to improve. The closer the viewer gets to the display they just receive an undisturbed display of images and outputs which makes it the best outdoor led manufacturers. The brightness and high resolution images in any shape or size are generated with the help of these high tech LED video walls to provide the best outdoor experience and delivery a seamless experience with a variety of options.

Video walls are a great way to increase the professionalism of your event . LCD is the abbreviation for liquid crystal display . LCDs use fluorescent lights . These fluorescent lights are placed behind the screen . LCDs are thicker than LEDs and not as energy efficient as LEDs . On the other hand , LED is the abbreviation for Light emitting diodes . LEDs use light emitting diodes . These diodes are generally placed behind the screen or around the edges of the screen . LEDs are thinner than LCDs and much more energy efficient . An LED video wall is made up of many smaller LED panels . Each panel has innumerous tiny light sources called light emitting diodes ( LEDs ) that can change color to create a large image that is split and distributed among all the LED panels in the LED video wall . An LCD video wall has a large surface made up of large and numerous LCD screens . The LCD screens have thinner edges called as bezels . Typically , LCD video walls are 5 screens high and 5 screens across . LCD video walls typically don’t go larger than this . Comparison Between LED Video Walls and LCD Video Walls . LED Size - There isn’t a maximum size for a LED video wall . You can use as many LED panels you want to make a LED video wall . There are no limitations to the width and height of a LED video wall . You can combine the screens as you want. COST- LED video wall is the most expensive video wall option . Installation - Installation time for LED video walls is much more than LCD video walls . It can take multiple days to install a LED video wall depending on the wall size . Brightness - An LED video wall can get face meltingly bright . So , its great for an outdoor venue . Power Requirements - LED video walls have a much low power requirement than LCD video walls . This makes LED video walls affordable than LCD video walls in the long run even if the installation charges for LED video walls is higher than LCD video walls . Loading Requirements - LED video walls are comparatively light weight and portable than LCD video walls . LCD VIDEO WALLS SIZE - Generally, LCD video walls are about 16’ wide and 10’ tall . COST- LCD video walls are usually less expensive than LED video walls . Installation - Installing LCD video walls takes lesser time than LED video walls . It takes minimum half a day to install a LCD video wall . Brightness - LCD walls are also very bright but they are designed to be indoors . LCD video walls are also not waterproof like LED video walls . Power Requirements - LCD video walls require a lot of power . Each screen requires at least 4 amps . This makes LCD video walls more expensive than LED video walls in the long run irrespective of the initial installation cost . Loading Requirements - LCD video wall screens come in large containers . This , takes up lot of space and makes it difficult to transport to the desired location . So , in conclusion , LED video walls are more expensive than LCD video walls . But LED video walls can be of any size and shape . There are no limits to its construction . Whereas LCD video walls have limited size and shape options . But LCD is more affordable cost wise . LED walls are better suited for outdoor events or venues and LCD walls are better suited for indoor venues or events . LED video walls are much more energy efficient than LCD video walls .

A video wall is basically a setup of multiple monitors or television sets or video projectors . They are tiled
A video wall is basically a setup of multiple monitors or television sets or video projectors . They are tiled together to form one large display screen . LCD panels , blended projection screens , direct view LED arrays , etc. are used for video walls . Generally, video walls are used instead of a large display screen because of the ability to customize tile layouts , greater screen area per unit cost , and greater pixel density per unit cost . Video walls are generally found on airports , in stadiums , in concerts , control rooms , etc. The main function of a video wall is that it serves as an advertisement platform for large public venues . People can view it from long distances . For e.g. - the video wall at Mc Carran International airport . It serves as an advertisement platform for approximately 40 million passengers passing through the airport annually . Another example of a video wall is the video wall in Oakland International Airport’s baggage claim is designed as such that people can view it from long distances . Video walls can also be used at smaller venues . It allows the people to view the screen at a long distance as well as up close . Distant observers can easily view pictures and it provides the nearby observer enough resolution to read the information displayed . For e.g.- the lobby of the Lafayette Library and Learning Center . Screens generally used for video walls usually have narrow bezels so as to minimize the gap between active display areas, and are built with long - term serviceability . These types of screen generally have a built in controller / processor to split the display video or image across the number of screens in the video walls. Simple video walls can be operated from multi-monitor video cards . Complex video walls may need specialized processors which are specially designed to operate large video walls . There is a device that splits a single image into different parts and displays it onto individual screens . It is called a Video Wall Controller /Processor . There are 2 types of video wall controllers / processors – 1.Hardware based controllers / processors . 2.Software based PC and video card controllers / processors. Hardware based controllers / processors are electronic devices built for a specific purpose . Usually, they are built on an array of video processing chipsets and do not have an operating system . The most simple hardware based video controller / processor is the single input, multiple outputs scaler . It takes up only one video and then splits the image according to the number of displays on the video wall . The main advantage of the hardware based video wall controllers / processors is high reliability and performance . Although high cost and less flexibility is a disadvantage . Most of the professional video wall displays have a integrated matrix splitter or processor . (controller) . This matrix splitter stretches the image from a single video input to all the displays in the video wall . Software based PC and video card controller / processor is a computer run operating system in a computer with special multiple graphic card feature . This approach is more expensive than the hardware based controller/ processor . But this approach can utilize the full resolution of the video wall unlike the hardware processor . Matrix, Grid and Artistic layouts - Matrix grid layouts are often limited to 2 X 2, 3 X 3, 4 X 4, etc. identical displays. Here, the aspect ratio remains the same but the image is scaled across a number of matrix displays . More advanced processors enable grid layouts of any dimension (1 X 5, 2 X 8). Here , the aspect ratio of the video wall maybe different from the ratio of the individual screens or projectors . Some advance video wall controllers allow you to output to multiple displays on a video wall . Transparent video walls is another type of a video wall. Transparent video walls combine multiple transparent LCD or LED screens to display video or images on a transparent video wall .
