Before knowing about the use of LED 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 for display. A LED wall is made up of many displays that work together in a cohesive manner to display the desired content. The LED walls are created by connecting individual LED 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 wall content look astonishing from any and every angle. Due to the LED technology used in the LED 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 LED wall technology. The LED 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 walls being so trending is the wall display screen support. This high tech digital signage is great for engaging customers by providing a world class visual experience of custom images and texts based on the time of day, business goal, location and even an individual customer's preferences. The LED 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 walls to provide the best outdoor experience and delivery a seamless experience with a variety of options. This digital technology is very much used in the advertising world and is one of the leading technologies in advertisement world. This is also used for the purpose of entertainment, education and to spread noble awareness as they are very eye catchy and attractive to the people and appeals to the viewers to have a look on the being displayed content. This is a great technology in advertisement as they can be very money yielding and putting logo and messages on the large LED wall panel helps in promotion to a escalated scale. It helps to make public aware of a company's product or factor without any effort and in a very small duration due to its exposure and eye catching display. The LED walls are now becoming a go to for people who are technology freaks due to its self mounted LED's and it's excellent and exceptionally high tech outdoor display delivery with the high resolution imagery and with multiple varieties of curved shapes. The LED walls can be used even in bright sun lit day without any hazard as they have high pixel pitch and are mostly proofed to weather. These walls are available at customizable sizes and shapes making them fit to the use of the user as per his convenience. The digital advancement of LED walls is an excellent source for market out there to enjoy the vision treat it provides with its high tech features and display, making it a want of the time and one of the best display systems, be it indoor or outdoor.
A LED wall is basically a setup of multiple monitors or television sets or projectors . They are tiled
A LED wall is basically a setup of multiple monitors or television sets or projectors . They are tiled together to form one large display screen . LCD panels , blended projection screens , direct view LED arrays , etc. are used for LED walls. Generally, LED 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 . LED walls are generally found on airports , in stadiums , in concerts , control rooms , etc. The main function of a LED wall is that it serves as an advertisement platform for large public venues . People can view it from long distances . For e.g. - the LED wall at many International airport . It serves as an advertisement platform for approximately millions passengers passing through the airport annually . Another example of a LED wall is the wall in Oakland International Airport’s baggage claim is designed as such that people can view it from long distances . LED 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 LED 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 image across the number of screens in the walls. Simple LED walls can be operated from multi-monitor comtrol cards . Complex LED walls may need specialized processors which are specially designed to operate large walls . There is a device that splits a single image into different parts and displays it onto individual screens . It is called a LED Wall Controller /Processor . There are 2 types of controllers / processors – 1.Hardware based controllers / processors . 2.Software based PC and card controllers / processors. Hardware based controllers / processors are electronic devices built for a specific purpose . Usually, they are built on an array of LED processing chipsets and do not have an operating system . The most simple hardware based controller / processor is the single input, multiple outputs scaler . It takes up only one image and then splits the image according to the number of displays on the wall . The main advantage of the hardware based LED wall controllers / processors is high reliability and performance . Although high cost and less flexibility is a disadvantage . Most of the professional LED wall displays have a integrated matrix splitter or processor . (controller) . This matrix splitter stretches the image from a single input to all the displays in the LED wall . Software based PC and control 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 LED 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 LED wall maybe different from the ratio of the individual screens or projectors . Some advance LED wall controllers allow you to output to multiple displays on a LED wall
1. VIEWING DISTANCE As the name suggests it means minimum distance from where a person will see the LED SCREEN.Finer
1. VIEWING DISTANCE As the name suggests it means minimum distance from where a person will see the LED SCREEN.Finer the pixel closer the view can be with utmost clarity. Its the main deciding factor for pixel of the LED SCREEN. 2.LOCATION This is the vital factor while choosing an LED WALL .Location decide your audience what type of people are really engaging with your videos or your content . 3. SIZE Size of the screen depends on your screen resolution. LED DISPLAY Screen needs to be bigger if its put up at a considerable height otherwise it wont be visible to the user clearly. 4.CUSTOMER SUPPORT/WARRANTY CONDITIONS There are hundreds n hundreds of small reseller in almost every city or state. They people just sell primarily on price without thinking about after sales service or customer support. They just stop communicating after selling LED DISPLAYS and hardly pick up phones or reply emails or messages. So while choosing LED VIDEO WALL, buying on price is seductive but risky as its not a small thing to invest in because once installed ant problem occurs these resellers who have not even established location or setup hardly provide any technical help.Lower price also means the components used while making are of low quality or used product as well. So check and clear the warranty conditions with online, onsite or offsite services.
