Abstract

Abstract A light emitting diode display apparatus is disclosed wherein a plurality of diodes mounted in a row on a vibrating member are used to create a display. The light emitting diode display may be used as an oscilloscope to display various types of signals. Alternatively, the diode display apparatus may be used in conjunction with a camera system wherein a similar row of radiant energy sensors, such as photocells, are mounted on a vibrating member synchronized with the vibrating member of the display in order to sense the subject matter to be displayed. The camera-display system may be connected together by means of lines or coupled together by means of a telephone system. The purpose of the above abstract is to provide a non-legal technical statement of the disclosure of the contents of the instant patent application and thus serve as a searching-scanning tool for scientists, engineers and researchers. Accordingly, this abstract is not intended to be used in understanding or otherwise comprehending the principles of the present invention hereinafter described in detail, nor is it intended to be used in interpreting or in any way limiting the scope or fair meaning of the claims appended hereto.
