Portable electronic display device

Abstract

Portable, electronic, indicia display apparatus, for use as a portable scoreboard, clock, and the like for athletic contests, and a portable display for commercial exhibitions, such as trade exhibitions and conventions, comprising (a) a portable remote display member having a panel upon which the desired information in the form of numbers, letters, and other indicia are displayed by a controlled energizing of electrical illumination elements, e.g. light bulbs, and (b) a portable control member, separate and remote from said display member, having a face panel capable of displaying essentially the same or more indicia displayed on the remote member face panel, and containing digital logic circuitry and manual input functions, e.g. switches and buttons, for controlling the indicia display on the remote member and control member face panels, with the system also being provided with a transmitter which transmits information from the control member to the remote display member via serial transmission of binary information. By means of logic circuits in the device of the present invention essentially all of the control circuitry is placed in the portable control member housing to provide a portable display device, useful as a basketball scoreboard and time clock, weighing less than about 75 pounds, and usually less than 50 pounds, for the entire assembly, including auxillary cable, carrying case, and supporting elements.
