Abstract

A display system and methods; in general, a plurality of display sub-assemblies collectively creating a viewing plane. Each display sub-assembly having a plurality of light emitting elements on a substrate with a plurality of substantially equal pixel gaps between light emitting elements. Bend gaps are provided between pixels that enable the display sub-assemblies to bend thereby creating a curved viewing plane. A mobile LED panel display may be formed of a plurality of LED display modules having a plurality of pixels, four or more casters, a battery powered supply, a media player (electrically communicating with the plurality of display modules for controlling the display of images on the LED panel display, and a removable content storage device and; thus, functions as a rugged, light weight, battery powered display to inform customers and passers-by about product and service offerings via a rugged person size mobile light weight battery powered display.
