Claims

[Claims for Utility Model Registration] A dot matrix light emitting display unit comprising an LED panel in which a plurality of light emitting diodes are wired in an X-Y matrix, and a drive circuit that drives each light emitting diode of the LED panel using a dynamic lighting method. In, the number of X-axes and/or Y-axes of the drive circuit is
A dot matrix light emitting display characterized in that one to three more axes are provided than the corresponding X-axis and/or Y-axis of the LED panel, and the more axes provided on the drive circuit are used as dummy lighting circuits. unit.
