An article (so-called ‘LED tile’) in an aluminium housing with dimensions of approximately 40 × 40 × 7 cm, including the following components: — light emitting diodes (LED) mounted on a printed circuit board with a pixel density of 72 × 72 and a brightness of 2 000 cd/m2, — connectors for the power supply (in and out), — connectors for the data input (in and out), — brackets and holes for mounting several tiles together. The article is presented for use in a modular LED video wall. It does not include a video processor. The LED tile, whether or not connected to other tiles, cannot display video images directly originating from a video source. It can only display signals originating from a dedicated video processor (so-called ‘digitiser’), which processes the signals and divides them over the total number of tiles in the LED video wall. The tile, when connected to the video processor, has the capability to display images in a large number (281 trillion) of colours.
