Abstract: Most large public displays systems are built with smaller modules populated with light emitting pixels devices which are then connected together to form a larger surface which is the combined surface area of all the modules. This construction method creates the problem that the supporting and connecting structure that holds the modules together uses a generally small but not totally negligible space between each pair of modules, which is devoid of light emitting pixel devices, which, in turn creates a darker space between the modules. This problem is aggravated by the fact that the modules are generally rectangular, which causes that their edges continue from edge to edge of the whole display, causing darker lines on the display surface, generally horizontal and vertical darker lines. This invention discloses adding light emitting pixel devices on the supporting and connecting structure so that the image is continuous across the full display area.
