Abstract: A plurality of filaments (8) are stretched in parallel on a rear plate (7), and an insulating plate (11) is provided so as to cover the filaments. In the insulating plate, a plurality of through-holes (12) are formed along the longitudinal direction of the respective filaments for exposing parts thereof. Each through-hole and phosphor layers (13), which are provided on the insulating layer adjacent to the through-hole, constitute one unit picture element. The respective phosphor layers (13) in the respective picture element are installed in a plurality of cavities (15) formed in a rib provided on a lower surface of the insulating plate, whereby separated from the neighboring phosphor layers. The respective cavities (15) function as a discharge room, with a light-transmissive front plate (16), formed on the rib, as a lid and a portion of the insulating plate corresponding to the phosphor layer as a bottom. The respective discharge rooms overlap the through-hole at one end in the longitudinal direction thereof. A part of the filaments is exposed to the discharge room via the through-hole so as to act as a cathode. In addition, an anode (17) exists respectively at the other end of the respective discharge rooms. In this manner, a luminescent panel for color video display, with a plurality of picture elements arranged in a matrix with a narrowed-pitch and a high density, is provided.

Abstract: PURPOSE: To reduce the cost and power consumption of a driving device for a gas discharge type display device. CONSTITUTION: Semiconductor switches 61 -6N are connected between each cathode K1 -KN and a common line X0 , the common line X0 is driven by a push-pull circuit 1 consisting of semiconductor switches FP, FN, and a power collection circuit 4 is connected to the common line X0 . A semiconductor switch FP is turned on only in the last and short period of a driving period TP for each cathode K1 -KN, and a semiconductor switch FN is turned on two times in a off period of the semiconductor switch FP in a driving period TP. When a scanning pulse voltage is applied, semiconductor switches 61 -6N are turned on in an previous ON period of the semiconductor switch FN, when holding pulse voltage is applied, semiconductor switches 61 -6N are turned on in an ON period succeeding the semiconductor switch FN and an OFF period before and after it, power collection operation is performed by the power collection circuit 4 in a period when the semiconductor switch FP is turned off and the semiconductor switch FN is turned off.

Abstract: PURPOSE: To dispense with an auxiliary discharge cell to simplify the structure of a device, reduce the power consumption, improve the efficiency, and enhance the luminance by three-dimensionally wiring an anode, a cathode and an address electrode in matrix. CONSTITUTION: An address electrode 22 on the lower surface of an insulating substrate 21 is provided to form a plural column arrangement, an anode 24 is provided to form a plural row arrangement, and arranged orthogonally to the electrode 22 in grade separation form. A cathode 27 on a light transmitting glass substrate 25, is aligned in parallel to the anode 24 every aggregate of row unit connected to the same cathode bus line 28 to form a plural row arrangement as the whole. In the drive of a device, a writing discharge is first performed between the electrode 22 and the anode 24 arranged in grade separation form to store the display content, and a keeping discharge is then performed between the anode 24 and the cathode 27 to perform a display emission. Thus, an auxiliary discharge cell is dispensed with to simplify the structure of the device, the screen is highly made fine, the manufacturing efficiency is improved, and the cost can be also reduced.

Abstract: PURPOSE:To simplify the panel structure of a display apparatus, lessen the electric power consumption, and extend the life of the apparatus by forming a discharge hole to expose at least a part of a first electrode to a dielectric layer in a discharge cell. CONSTITUTION:A group of first electrodes 11 and a group of starting electrodes 12 formed on an insulating substrate 10 are coated with a dielectric layer 13 and a group of stripe-like second electrodes 15 are formed on a transparent glass substrate 14. The group of the electrodes 15 are kept from the group of the electrodes 11 and the group of the electrodes 12 at prescribed gap and so set as to face to these groups at right angles. Discharge cells 17 are positioned at the position facing to the group of the electrodes 11 and the group of the electrodes 15 at right angles and are composed of walls 16 which are arranged to form a lattice and discharge holes 18 are so formed as to expose at least a part of the electrodes 11 to the layer 13 in the cells 17. Furthermore, auxiliary discharge cells 19 are set at the position facing to the group of the electrodes 15 at right angles and slits 16a are formed in the walls 16 of neighboring cells 17 for the electrodes 12 and the auxiliary cells 19 are communicated with the cells 17. As a result, the resulting panel has a simplified structure, electric power consumption is lowered and the action life can be extended.
