When preparing to install giant LED video panels in a television studio, on a concert stage, or on an advertising screen, among many other examples, there are many details to consider.One of the most important and unknown to most viewers is how manufacturers prevent the dreaded moiré pattern from ruining the viewing experience offered by the screen.The pattern of moiré or moiré is an effect that originates due to the distance between pixels of a screen or what is the same, the size of the diodes used in the manufacture of the video panel and that show what appears on the screen .In general, the larger the individual light-emitting diodes, or LEDs, the cheaper the panels.However, as this measurement (known as pixel pitch) increases, the viewer has to stand further away from the giant screen to avoid the visual effect of undulating patterns that appear to move and vibrate, known as moiré patterns.Larger pixel pitches are often used on displays intended for billboards, outdoor signage, or corporate events, as they are often located far away, but most studio applications require presenters and cameras to be much closer, which means that the pixel pitch must be much smaller to avoid this undesirable effect.The most common distance between pixels in studio video walls is 1.5 millimeters.In this range, presenters can position themselves 1 to 1.5 meters in front of the video wall to avoid moiré.By upping the resolution to a 1.2-millimeter product, presenters can be positioned just 60 centimeters from video panels, which is ideal for small studio setups or video walls where presenters need to interact directly with the wall, for example, in the emission of weather forecasts.On the other hand, with a 1.8 millimeter pitch LED screen, 1.5 to 2.5 meters of distance are needed between the presenters and the LED panels, so it is important to keep in mind that even a fraction of a millimeter , in any case, can affect the position of everyone in the scene.All of these measurements may vary slightly depending on various factors, such as the shutter speed of the camera and the lighting conditions of the studio.There are also numerous points throughout the production workflow that need to be carefully considered to ensure everything is optimized to avoid moiré, such as graphics layout.For most applications, 1.5 millimeters seems to be the “sweet spot” at the moment to strike a good balance between the cost of manufacturing LED panels and the quality of the video output.Choosing a larger pixel pitch can be a way to save money, but it also creates a domino effect that often requires larger sets and, at the same time, can increase the need for more LED panels and scenic elements which is likely to make it more difficult to achieve the desired look.It might seem like an easy solution is to simply move the presenter's table or position people onstage differently, but since the set and studio were probably not designed with those positions in mind, it's usually not a viable option. .Let's remember that the goal of any video wall should be to get clear and sharp images behind the presenters to allow better narration, without ripples or vibrations that distort the image on the screen.Of course, the solution lies in the budget and experience of a reputable LED display manufacturer.The manufacturer's technicians can participate in the planning and find ways to fit the available budget without losing image quality.It is common for manufacturers to offer customers a sample of an installation with similar characteristics that has already been assembled previously, so that they can check the quality of the product in situ under certain conditions.Save my name, email, and website in this browser for the next time I comment.Type above and hit Enter to search.Press Esc to cancel.
