LED Wall is a modular structure made up of light panels used for applications on walls, shelves and outdoor areas. They allow the scrolling of animated graphics and monochrome, multicolored, or black and white characters. The LED wall is widely used for the propaganda of an event or a corporate brand.
Most of the LED modules are equipped with monochromatic or Full color LEDs, in order to meet the customer's needs. Each LED can be individually adjusted, and modules with different resolutions can be used. On the market we can find: - Warm white with color temperatures between 2700K and 3500K - Neutral white, color temperature about 4000K - Cool white with color temperatures between 5000K and 6500K - Monochromatic displays in colors such as red, green, blue or amber
When it comes to LED displays, brightness plays a key role. The candle (cd) is the unit of measurement of light intensity emitted by a single diode. The most common unit of measurement is the Nit, which differs from the candle as it indicates the brightness relating to an area corresponding to cd / m2 (nit). The values of an indoor LED display vary between 1000 and 1200 Nits. Much higher values are found in outdoor LED displays, between 5500 and 6000 cd / m2.
The image resolution depends on the pixel spacing and on the total size of the visible area, generally made up of several modules. The interaxis between pixels is chosen according to the reading distance. There are different types of modules with pixel spacing ranging from 1.87 to 20 millimeters. The smaller the pixel spacing, the higher the resolution per module. For example, a 4x3 meter display with a standard distance between centers of 3.91mm will have a resolution of 1024x768 pixels. The choice of modules depends on the size of the areas to be set up, in fact, to prepare small areas, modules with smaller extensions are used.
Another very important aspect is the control of the individual modules, which is usually done by a CPU. There are two varieties of controllers: the first type allows you to view content in real time from a video source, while the second type has an independent internal memory that allows you to view the data independently. The choice of the controller is made according to the display itself. The modules are connected to the CPU using specific flat cables and are adequately powered (normally 5VDC). Thanks to these controllers it is possible to display contents such as texts, images and videos with a frame rate of up to 60 frames per second.
The LED modules can be assembled together both horizontally and vertically until the desired dimensions are reached. The modules are connected in cascade both from an electrical point of view (power supply) and from an electronic point of view (signal). The power supplies will be sized according to the overall power consumption of the LED display. Data transmission usually takes place via the LAN. Furthermore, depending on the application, it is possible to use different interfaces to communicate with LED displays (Wi-Fi, LTE, etc). The modules are fixed using integrated threaded bushings. The use of standard connections and fixings facilitates the assembly and disassembly of the panels.
The possible fields of application are extremely varied. The modules can be used in the industrial sector (signaling, recall of alarm messages, display of production data, etc.) and in advertising information (from small shops to large trade fairs or concerts). The variety of applications is possible thanks to the flexibility and modularity of this product.
