Abstract
An LED display system having an LED module for reducing dark line defects. LED modules arranged adjacently in an LED display system form seams therebetween. An LED module for reducing dark line defects includes a set of imaging pixels for generating an image and a set of illuminating pixels for generating seam illumination through the seams. Seam illumination is directed through the seams directly or by a reflector integral with or attachable to the LED module or to a coupling assembly of the LED display system. The illuminating pixels may be controlled to track colour or intensity of the image being generated by imaging pixels.
Claims23
An LED display system comprising:
- a coupling assembly for securing LED modules in adjacent arrangement;
- a first LED module and a second LED module, the first and second LED modules having imaging sides with sets of imaging pixels disposed thereon for generating imaging illumination viewable from an imaging direction, the first and second LED modules coupled with the coupling assembly and situated adjacently to form a seam therebetween, the seam defining a plane between the first LED module and the second LED module, the first LED module having a rearward side, opposite its imaging side, with a set of illuminating pixels disposed thereon;
- a set of illuminating pixels situated rearward of the first and second LED modules for generating seam illumination through the seam;
- and
- a reflector situated rearward of the first and second LED modules, the reflector extending from one of the first LED module, the second LED module, and the coupling assembly, toward the plane of the seam, to direct the seam illumination through the seam.
