Unlike HP's earlier multi-digit handheld calculator displays, whose dies are molded directly into an epoxy carrier, the 5082-7446 has a more modern construction, with the dies mounted on a PCB carrier and covered with a lens-equipped plastic lid. 12- and 15-digit displays of this construction style were used in HP's second generation 'Woodstock' handheld calculators and 'Topcat' desktop calculators, respectively.
