Abstract: A light emitting diode (LED) display is provided, including an array of LEDs comprising a first set of LEDs, and a second set of LEDs, alternating with the first set of LEDs, in a grid pattern. A driver drives the first and second set of LEDs according to, respectively, a first and second image. The display further includes a monolithic wire-grid polarizer, in front of the array, comprising first and second regions configured to respectively polarize light from the first and second set of LEDs, according to, respectively, a first linear polarization state and a second linear polarization state perpendicular to the first linear polarization state. The first and second regions are respectively aligned with the first and second sets of LEDs. A quarter-wave retarder is located in front of the wire-grid polarizer, for converting the first and second linear polarization states into respective circular polarization states.

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.
