2017
At CES 2017 Sony showcased the CLEDIS ™ (Crystal LED Integrated Structure) with a Crystal LED video wall approximately 32 by 9 feet with a resolution of 8000 x 2000 pixel. According to Sony it is composed of single display modules measuring 17 7/8" (463.6mm) by 15 7/8" (403.2mm) each. The individual modules were not visible to the human eye. Due to the modular structure of the system theoretically any resolution and size could be possible according to a Sony representative.
