Abstract: A photoconductor gas discharge display is adapted for such rapidly moving images as television pictures by means of the present invention wherein the photoconductive elements (abbreviated as PC elements) are illuminated in advance of the addressing thereof so the impedance of each element will be low at the time of addressing. Time controlled means are provided for causing rows of PC elements to be illuminated in succession and in advance of the addressing thereof. The illuminating of the rows of elements is accomplished by gas discharge chambers disposed adjacent thereto. Each PC element opposite the gas discharge chamber has a photosensitive resistor connected thereto by which voltage signals are applied to the PC element and each PC element must be in illuminated condition for the voltage signal to be effective when applied to the element. The invention functions by pre-illuminations to achieve a sufficiently low impedance level so as to be illuminated by an addressing from a voltage signal.
