Embodiment Construction

[0031] Hereinafter, an embodiment of the manufacturing method of the plasma display panel of the present invention will be described in detail with reference to FIGS. 3 to 6 b in the accompanying drawings.

[0032] Fig. 3 is a sectional view of a plasma display panel based on the present invention.

[0033] Referring to FIG. 3 , the PDP discharge cell based on the present invention is provided with scan electrodes Y and sustain electrodes Z on the upper substrate 40 and address electrodes X on the lower substrate 42 .

[0034] Scan electrode Y and sustain electrode Z include transparent electrodes 44Y, 44Z and bus electrodes 46Y, 46Z provided on one edge of transparent electrodes 44Y, 44Z and narrower than transparent electrodes 44Y, 44Z, respectively. The transparent electrodes 44Y, 44Z are generally provided on the upper substrate 40 using indium tin oxide (Indium Tin Oxide: ITO). The bus electrodes 46Y, 46Z are provided on the transparent electrodes 44Y, 44Z made of a meta...

Abstract

The method includes following steps: preparing motherboard with multiple array areas; coating film on each array areas, which are spaced out a certain distance with scribing lines, and then patternizing the film so as to form film pattern; scribing step along scribing lines by using array area as a unit. Using silk-screen printing photographic plate, the method sets up thin film on array areas except warning regions between array areas. Using laser to etch array areas selectively, the method reduces etching area so as to raise production efficiency.

Description

technical field [0001] The invention relates to the technology of the plasma display screen manufacturing method, in particular to a plasma display screen manufacturing method capable of improving production efficiency. Background technique [0002] A plasma display panel (Plasma Display Panel: hereinafter referred to as "PDP") is a display device made by utilizing the principle that phosphors can emit visible light when ultraviolet rays generated by gas discharge activate phosphors. Compared with the cathode line tube (Cathode Ray Tube: CRT) which still dominates the display equipment so far, the PDP has the advantages of being thinner and lighter, and capable of displaying high-definition large-scale images. A PDP is composed of a plurality of discharge cells arranged in a matrix form, and one discharge cell is a pixel of a screen. [0003] The discharge cell on the original 3-electrode AC surface discharge type PDP consists of the following parts: the upper plate includi...
