ABSTRACT:
The disclosure is of a display panel, known as a bar graph and used for displaying bars of light of varying length. The panel includes an anode and a series of cathode bars, the cathodes being connected in three phases of groups which are formed by a trifilar winding on an insulating base plate. The anode for the panel may be formed on the face plate which is hermetically sealed to the base plate to form a gas-tight envelope which is filled with an ionizable gas.
The principles of the invention can be used to make other types of panels having electrodes connected in groups.
