You know them from Times Square, from concerts and from football stadiums: large displays or video walls with scrolling texts, colorful pictures and videos. They consist of many interconnected LED panels that are interconnected to form a large display panel. The distance between the pixels is between 2mm and 6mm, depending on the model. At a certain distance, the human eye can hardly see the individual pixels.
However, this article is not about building large displays for the garden party, but rather using individual panels for chic lighting projects. The panels are ideal for building small, coarse pixel displays that exude the retro charm of the 8-bit home computer era in the living room, hobby room, office, arcade hall or shop. This allows graphics and animated GIFs to be displayed. And to put it in Loriot’s words: “There is always a big hello …”
The most common panels are made with 32 × 32 RGB pixels, whereby the distances (Pitch) between the pixels are between 2mm and 6mm. But they are also available with 64 × 32 pixels. The panels do not have any intelligence of their own and must be controlled by an external controller.
