A Review of Panel-Type Display Devices

A review of the activities of various governmental, industrial, and academic institutions is made in the field of panel display devices. These devices are thin sheets which can display luminescent information. Insofar as possible the present state of the art is indicated. The displays are grouped as: evacuated, solid, gas, liquid and mechanical. Among the evacuated types are listed the thin cathode ray tubes and the image intensifier. The solid-type displays employ the electroluminescent panel in conjunction with an xy matrix of electrodes. Recent progress in panels of the above type with memory are included as well as a brief discussion of solid-state image intensifiers. Descriptions of proposed gaseous displays as well as of liquid and mechanical displays are included. A brief discussion of switching circuits is included. Actual as well as possible applications of these devices are listed.
