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.
