Curved dead front display

摘要

A curved dead front display assembly is provided which includes a first plastic layer, a transparent structural plastic layer, a mask layer with light transparent windows defining at least one graphic, a baffle layer having light transmitting hollow chambers, and a printed circuit board featuring light emitting diodes and electrical signal connections. The curved geometry achieves a sharp graphic image by electrically adjusting energy to each of the LEDs.

主权项

1. A curved dead front display assembly comprising:
a first plastic layer having outer and inner surfaces; a transparent structural plastic layer having a first and second surface, the first surface contacting the inner surface of the first plastic layer; a mask layer with an array of light transparent windows defining at least one graphic and having a front and a rear side, the front side contacting the second surface of the structural plastic layer; a baffle layer having a plurality of hollow chambers allowing light transmission from an open end to an exit end, the chambers being separated from one another by light opaque walls, the exit end contacting the rear side of the mask layer; and a printed circuit board having electrical signal connections and an upper surface comprising a plurality of light emitting diodes, each of the light emitting diodes being aligned with one of the plurality of chambers, the upper surface contacting the open end of the baffle layer.
