Abstract: An improved solenoid and reset pin for a modular display apparatus for displaying indicia at a front thereof having a frame for rotationally mounting a plurality of pixels. Each pixel includes first and second display faces joined along respective adjacent edges. A triggering mechanism has a plurality of solenoids adapted for selective actuation to rotate selected ones of the pixels for changing the pattern of the desired display indicia and a plurality reset pins to return the pixels to an original position. The reset pins and the plungers for the solenoids include a spring and a rod extending axially outward from said spring to provide radial flexibility.

Abstract: A modular display apparatus for displaying indicia at a front thereof has an inner frame with horizontal support beams, the inner frame supporting a plurality of grid modules, at least one grid module being located above another. A plurality of pixels rotationally mounted to the grid modules each include first and second display faces joined along respective adjacent edges. The pixels have a center of gravity located on each pixel so as to interact with an external force applied to the pixel and provide a complete rotation, with a minimum of bounce, to display a desired display face. A triggering mechanism has a plurality of solenoids adapted for selective actuation to rotate selected ones of the pixels for changing the pattern of the desired display indicia controlled by an electronic signal transmitted from an electronics system.
