Abstract: PURPOSE: To provide a highly reliable and high quality of light emitter by constituting a spacer for retaining the space between a light emitting face and the substrate at the back, dividing it into a base layer and a spacer part body, thereby enabling the desired mechanical strength and dimension to be kept accurately to prevent breakdown. CONSTITUTION: A base layer 28 is provided between a transparent electrode 1 and each R, G, and B of a phosphor element, and a wide base layer 8 is made for every three trios of R, G, and B, and thereon a spacer body 9 is made by stacking printing to constitute a spacer 10, and a fluorescent face panel 14 and a rear panel 16 equipped with an electrode structure 15 are kept at a specified interval. This way, the base layer 8 is made wider than the spacer body 9 to prevent the collapse, and also the height of the spacer can be adjusted into specified height by the number of applications in layers, according to the distance between the panels 14 and 16, and the dimension of the interval can be maintained accurately.

Abstract: PURPOSE:To provide a fluorescent screen forming method by an electrodeposition method by which a phosphor film having a uniform film thickness can be formed by the electrodeposition method in a field emission type cathode and sticking of phosphor to an ineffective image screen part outside of a fluorecent screen part can be eliminated. CONSTITUTION:In an electrodeposition method, a guard electrode 3 is arranged around (in an ineffective image screen part) of a prescribed electrode (an electrode pattern formed in an effective image screen part) 1, and inverse bias voltage to electrode voltage for electrodeposition is impressed on the guard electrode 3 in electrodeposition liquid 12G (12B, 12R and 12M) in an electrodeposition tank 11. An electric field in the vicinity of an end part of an effective image screen electrode part can be controlled by this voltage control, and as a result, a phosphor sticking quantity inside of an effective image screen electrode can be controlled while including an effective image screen electrode end part. Thereby, a phosphor film having a uniform film thickness can be formed on a fluorescent screen forming panel surface on the prescribed electrode 1, and sticking of phosphor to the outside of a fluorescent screen part can be eliminated.

Abstract: PURPOSE:To improve scanning line density by arraying picture elements so that odd-numbered fields and even-numbered fields shift by one or two lines. CONSTITUTION:A matrix display part 4 employs a display driving configuration wherein every two adjacent lines of picture elements of R, G, and B form one display line element and every three adjacent lines form two display line elements. For example, groups of respective picture elements R, G, and B in every two adjacent lines are driven for display in odd-numbered fields without any omission as shown by a chain line (a) to constitute display line elements L1, L3, L5..., e.g. scanning lines, and groups of respective picture elements R, G, and B in every two adjacent lines shifting from the combinations in the even-numbered fields by one line are driven similarly for display in even- numbered fields without any omission as shown by a chain line (b) to constitute display line elements L2, L4..., e.g. scanning lines. Consequently, the scanning line density is improved and high picture quality is obtained.

Abstract: PURPOSE:To prevent the unevenness of brightness by providing an electron beam collection electrode opposing a low voltage shield electrode at the side of a cathode and forming an electrostatic focusing electron lens therein. CONSTITUTION:An electron beam collection electrode 21 is so provided as to oppose a low voltage shield electrode 8 and an electrostatic focusing lens system is formed on the basis of an electric field formed between the aforesaid electrodes 8 and 21. Consequently, a primary electron emitted from a cathode 4 can be directed to the inside of an electron path (h) focusing and collecting a wide range of electrons exceeding the inner diameter phis of the electron beam penetration hole (hs) of the low voltage shield electrode 6 and leading to a fluorescent material picture elements R, G and B. Theoretically, therefore, it becomes possible to employ all of electron beams directed forward from the side of emission from the cathode 4, and the utilization factor of the primary electron can be increased. According to the aforesaid construction, the uneven ness of brightness can be effectively evaded.

Abstract: PROBLEM TO BE SOLVED: To selectively deposit homogeneous electrochemical thin films at need on a large-area metallic thin-film or transparent conductive film by bringing an electrolyte with a small area into contact with a substrate surface and sweeping the boundary thereof at the time of depositing the electrochemical films on the conductive substrate. SOLUTION: A glass panel 1 is held above an electrolyte cell 3 by directing the front surface of an Ni film 2 downward. A columnar cathode 4 is brought into contact with this Ni film 2. The electrolytic cell 3 for Ni plating has the width sufficiently smaller than the width one side of the Ni film to be deposited and is internally filled with the electrolyte 6. The open end of the cell is directed upward and the electrolyte 6 comes into contact with the surface of the Ni film. The base of the electrolytic cell 3 is provided with an anode 8 and a contact liquid boundary 7 is formed by the electrolyte 6 and the Ni film 2. While current is supplied between the cathode 4 and the anode 8, the contact liquid boundary 7 is swept by moving the glass panel 1 in an arrow direction, by which the thin films of the Ni are selectively and uniformly deposited on the Ni film 2.
