Abstract: PROBLEM TO BE SOLVED: To subject a discharge electrode to aging capable of performing uniform activation treatment. SOLUTION: A discharge cell 2 having an opening is assembled by joining a rear side substrate 8 on which plural discharge electrodes 9 are formed beforehand and a dielectric sheet 3 with each other for manufacturing a plasma address display device. Then the gas which can discharge electricity is introduced to the discharge cell 2 via the opening. Further the opening is sealed to tightly close the inner part of the discharge cell 2. After that, a display cell 1 is assembled by joining a front side substrate 4 on which plural signal electrodes are formed beforehand and the dielectric sheet 3 with each other. Finally an electrooptical substance is disposed in an inner part of the display cell 1. An aging process for activating the discharge electrodes 9 by repetitively applying electric fields to the discharge electrodes 9 via the dielectric sheet 3 from the out side of the discharge cell 2 and repetitively discharging electricity in the inner part of the discharge cell 2, is performed at least once in any step after the discharge cell assembling stage.

Abstract: PROBLEM TO BE SOLVED: To remove a delay at the rise of discharge without increasing a discharge time and discharge current. SOLUTION: A discharge cell device consists of a cell part 2 and a circuit part 232. The cell part 2 has an insulating substrate 4, at least two electrodes A, K formed thereon, and a dischargeable gas distributed in contact with these electrodes A, K. The circuit part 22 makes gas discharge by making one electrode A at an anode potential and the other electrode K at a cathode potential every time a selection period separated by non-selection periods comes. When the selection period ends and returns to the non-selection period, the circuit part 22 changes over at least one electrode K of the two to a prescribed potential higher than the anode potential to raise the surface potential VG of the substrate 4 up to the level between the anode potential and the prescribed potential, and accelerates the rise of the discharge in the next selection period.

Abstract: PROBLEM TO BE SOLVED: To eliminate the deterioration in dynamic resolution when an interlace operation is carried out without changing a driving circuit by shifting scanning lines by one scanning line-component by every filed and successively executing scanning by combinations of different discharge electrodes. SOLUTION: The scanning lines are scanned at a ratio of one piece per two pieces in interlace scanning of 2:1. For example, even lines are successively selected in even fields and odd lines are selected in odd fields. Data strobe signals are successively impressed to the cathode electrodes K2, K4,... of the even number place in the even fields and the data strobe signals are successively impressed to the cathode electrodes K1, K3,... of the odd number place in the even fields. Electric discharge is induced between the anode electrodes A1, A2,..., An by the impression of the data strobe signals to the respective cathode electrodes A1, A2,..., An and a discharge plasma is generated. The width of the discharge plasma is set at >=2 times the scanning unit (the pitch of the discharge electrode group 7).

Abstract: PURPOSE: To provide a drive system for a plasma address display panel capable of preventing its adverse effect even when an omissive position exists on a partition parting discharge channels. CONSTITUTION: A flat panel 1 is provided with a laminated structure alternately superposing a plasma cell having plural discharge channels 5 individually parted by the partitions along the line in the horizontal direction and a liquid crystal cell having signal electrodes 4 orthogonally intersecting with the discharge channels 5. A scan circuit 2 discharge drives the discharge channels 5 successively selectively to scan respective lines. A signal circuit 3 applies an image signal to the signal electrodes 4 synchronizing with the line scan to write in respective lines. When the omissive position exists on the partition parting a pair of discharge channels 5 adjacent each other, the signal circuit 3 writes the image signal of the same polarity in two lines along a pair of relevant discharge channels 5, and writes the image signal of an opposite polarity alternately in other lines. The scan circuit 2 performs a replacement scan of lines in the position of a pair of relevant discharge channels 5 so that the polarity of the image signal applied to the signal electrodes is inverted regularly and positive/ negative alternately along a time base.

Abstract: PURPOSE: To improve the alignment accuracy between printing patterns in a method for laminating and printing screens by superposing printing patterns and transferring these patterns on a substrate. CONSTITUTION: The first printing patterns 2 and the second printing patterns 3 are transferred in superposition on the substrate 1 by successively using plural screen masks. The screen masks are previously provided with alignment marks and the first alignment marks 4 are transferred onto the substrate simultaneously at the time of transferring the first printing patterns 2 on the substrate 1. The alignment of the upper second printing patterns 3 to the lower first printing patterns 2 is executed by using the first alignment marks 4 as references. At this time, the second alignment marks 5 transferred by the next screen mask are included in the first alignment marks 4 transferred by the previous screen mask. Then, the external shape of the first alignment marks 4 are preserved as they are and are usable as the references for the alignment in the perfect form at the time of forming the third printing patterns.

Abstract: PURPOSE:To improve the reliability for a long period by suppressing the sticking, etc., of an electro-optic material even if a write data voltage has a DC offset. CONSTITUTION:This is an equivalent circuit for one pixel of a plasma address display device. Then DS is a data voltage, RLC and CLC are the resistance and capacity of a liquid crystal layer 7, and RG and CG are the resistance and capacity of a dielectric sheet 3. Further, SW1 is a virtual switch consisting of a discharge channel 12 and has a DC offset VOFF depending upon a discharge state, and consequently the data voltage written in the liquid crystal layer 7 has the DC offset. A filter circuit composed of the liquid crystal layer 7 and dielectric sheet 3 is given high-pass characteristics by satisfying RLC/(RLC+RG
