Abstract

The preferred embodiment of the present invention is an outer light transmissive envelope consisting of transparent rubber-like polyvinyl chloride (PVC) containing light emitting diode (LED) display panels comprised of a plurality of LED elements arranged in matrix formation. Aforementioned apparatus will have flexibility characteristics giving it the ability to conform to curved vertical surfaces that are flat and non-porous. Suction cup devices made of PVC will be bonded to the light transmissive envelope thus enabling the LED apparatus to be attached to vertical surfaces, making the unit self-supporting.
