Abstract:
Almost only choice by a secondary electron emission layer/protection layer covering the dielectric layer of an AC type PDP has been magnesium oxide (MgO) that is unstable during the production process and difficult to form, thus posing a serious production problem. An AC type PDP constructed such that, instead of covering the surface of a dielectric layer with a dielectric material such as MgO, an insular electrode is made by forming a conductive material such as nickel, aluminum, magnesium and lanthanum hexaboride into an insular shape, and the insular electrode is allowed to capacity-couple with a lower-layer bus electrode by means of an electrostatic capacity formed by a dielectric layer to operate the insular electrode as a sustained electrode.

Abstract:
A video display system employing a flat display panel of the crossed-grid or X-Y matrix type, signal sampling means, and "write in" and "read out" memory circuits serially connected between the signal sampling means and the display panel, is provided with a novel signal control means connected to the "write in" and "read out" memory circuits whereby the number of lines or leads for distributing signals mainly from the "read out" memory circuits to the display panel is greatly reduced. The sampled signals are digitally coded and transmitted sequentially to the "write in" memory circuits during an effective picture period of a horizontal scanning period. Each of the "read out" memory circuits includes a plurality of serially connected memory devices forming a shift register and has a single input terminal to which signals are transmitted from the corresponding "write in" memory circuit in a short interval between successive effective picture periods, and a single output terminal connected to a corresponding one of the Y-driving circuits of the display panel. The signals are read out from lower bits to higher bits with different intervals corresponding to the weight of the digitally coded signal so as to drive each Y-driving circuit with the signals read out from the output terminal of the respective "read out" memory circuit.
