Abstract: Disclosed are a plasma display capable of preventing deterioration of display contrast deriving from priming discharge, and of minimizing a power consumption, and a driving method therefor. The plasma display comprises: a plasma display panel in which first, second, and third electrodes are arranged alternately parallel to one another on a first substrate, and fourth electrodes are arranged orthogonally to the first electrodes on the first substrate or a second substrate; a first electrode selection driver for selectively driving the first electrodes; a second electrode driver for driving the second electrodes, and a third electrode driver for driving the third electrodes. First display cells are formed at intersections between the first electrodes and second electrodes and the fourth electrodes, and second display cells are formed at intersections between the first electrodes and third electrodes and the fourth electrodes. The first display cells and second display cells are alternately and repeatedly allowed to glow for display for the purpose of achieving interlacing display. In the plasma display, during a reset period, the second electrode driver and third electrode driver apply voltages to the second and third electrodes respectively so that priming discharge can be induced in third cells. The third cells for priming are formed with the second electrodes and third electrodes.

Abstract: Strip colour filers (24) lie in parallel on the inner side of a front plate (20). A dielectric layer (25) is formed at defined intervals in sections corresponding to the respective filters (24). A weak fluorescent layer (26) is formed on the dielectric layer (25). Anodes (22) are formed on the fluorescent layer (26) corresponding to the filters (24). Each anode (22) has a light-passing opening (22a) formed in the section corresponding to the holes (25a) of the dielectric layer (25). Thus, optical interference between neighbouring cathodes (23) in the direction of a scanning line is prevented and uniform light intensity is achieved. ADVANTAGE - Can produce pictures of uniform brightness over whole screen. Reduces light intensity differences due to different emission efficiencies of fluorescent material. Produces good picture quality and reduces optical interference.

Abstract: Plasma visual display screen of the flat, discharge type, making it possible to obtain high brightness, long lifetime of the luminescent layer and maximum effectiveness of the light emission by producing all the electrodes on the rear panel (10) in glass. It comprises auxiliary anodes a part (11a) of which is exposed along a passage (17) for electrically charged particles so as to be insulated by a first dielectric layer (12) and to cross the display cathodes (13a, 13b) produced on the rear panel (10) in glass. The second dielectric layer has a plate (14') for stopping the light in order to hide the auxiliary display region of the auxiliary anode to the front, the stop plate projecting and extending to the upper level of the uncovered auxiliary anode.

Abstract: A gas discharge panel includes several pairs of column (X) electrodes arranged on a first substrate and several pairs of row (Y) electrodes arranged on a second substrate, the column and row electrodes being orthogonally oriented and in spaced, opposed relation to define therebetween a gap filled with an ionizable gas. In a first driving configuration, a corresponding electrode of each pair of (X) electrodes is selectively driven by an (X) address driver and similarly a corresponding one of each of the (Y) electrode pairs is selectively driven by a (Y) address driver. The other electrode of each of the (X) and (Y) electrode pairs then is connected in common to respective (X) and (Y) sustain voltage driver terminals. In a further embodiment, each of the (X) and (Y) electrode pairs is arranged in corresponding groups of electrode pairs, each group including a common number of such pairs. First electrodes of each pair of each group are connected to a common output terminal of an address and sustain voltage driver; thus, plural address and sustain voltage driver outputs corresponding to the plural groups are employed for each of the (X) and (Y) electrode pairs. The second electrodes of corresponding pairs of the plural groups are connected to respectively corresponding, further common output terminals of address and sustain voltage drivers; thus, a plurality of further common terminals corresponding to the number of electrode pairs in each group are provided, as to each of the (X) and (Y) electrodes. The panel as thus configured affords decoding of addressing signals applied to the common terminals by means of plasma coupling within the panel whereby the discharge point or cell defined by a desired electrode of each of the column and the row electrode pairs can be addressed selectively. A further embodiment provides shifting of the display to successive positions in either the (X) or (Y) directions.

Abstract: A self-shift plasma display panel based on the surface discharge is disclosed. This plasma display panel has two electrode groups of shift electrodes and channel electrodes which are positioned so that the two types of electrodes cross at right angles on the same substrate facing a discharge space filled with gas capable of ionization. The shift electrodes are alternately connected to first and second buss at intervals of one electrode, and the channel electrodes are alternately connected to third and fourth buss at intervals of one electrode. The above-mentioned four buss are connected to a four phase alternating voltage source. A discharge spot produced between a shift electrode and a channel electrode is shifted along the channel electrode by means of the four phase alternating voltage applied to the four buss in order.

Abstract: A gas discharge panel provides one or more shift channels for discharge spots, said shift channel (s) being composed of 2 or more electrode groups on each of a pair of substrates arranged oppositely across a discharge gap. Electrodes of each group are provided alternately and periodically on each substrate with the electrode patterns on each substrate such as to define said shift channel(s). The electrode layout eliminates the need for crossover areas in the leading out of electrodes and is very useful for realizing high resolution and low cost AC driven self-shift plasma display panels.

Abstract: Two arrays of main X and Y electrodes are juxtaposed with two arrays of auxiliary electrodes in two parallel plane respectively. Two half illumination or extinction pulses less in magnitude than a discharge voltage across the opposite arrays and opposite in polarity are applied to selected ones of the X and Y electrodes to initiate or terminate an electric discharge or discharges across them. A pulse train including positive pulses alternating negative pulses is applied across the arrays of auxiliary electrodes to be discharged across those auxiliary electrodes juxtaposed with the selected X and Y electrodes upon each inversion of the pulses polarity after the first discharge.
