Embodiment 1

[0013] figure 1 is a schematic structural diagram of a plasma display panel according to an embodiment of the present invention. Such as figure 1 As shown, the plasma display panel includes an upper substrate glass 1 and a lower substrate glass 2 . The upper substrate glass 1 has sustain electrodes (also referred to as X electrodes) 8 and scan electrodes (also referred to as Y electrodes) 9 on the surface of the upper substrate glass 1, and BUS electrodes are formed above the transparent electrodes. Then, the upper substrate glass 1 further includes: a transparent medium 10 with a thickness of about 20 to 40 microns located above the above-mentioned electrodes, so as to protect the electrodes. In addition, the upper substrate glass 1 may further include: a protective medium on the transparent medium 10 , such as a magnesium oxide protective film, so as to avoid particle bombardment. In order to improve the contrast of the display screen, black bars 7 can also be made on the...

Embodiment 2

[0021] Such as figure 1 and 2 As shown, the lower substrate of a plasma display panel according to this embodiment includes: figure 2 The address electrode 3 of the structure shown, the address electrode 3 includes: a first part 5 and a second part 6, when connected to the upper substrate, the first part 5 corresponds to the position of the X electrode 8 of the upper substrate, and the second part 6 corresponds to the position of the Y electrode 9 of the upper substrate, wherein the second part 6 is wider than the first part 5 . Since the address electrodes 3 having such a structure are included, the lower substrate according to the present embodiment increases the capacity of the capacitor during the address discharge process and improves the address efficiency. Preferably, the width of the second portion is 1.3 to 1.7 times the width of the first portion.

[0022] Compared with the existing method of overall widening the address electrodes, although the lower substrate a...

Embodiment 3

[0026] A method of fabricating the lower substrate and the plasma display panel in the embodiment of the present invention will be described below.

[0027] In the embodiment of the present invention, by using different thicknesses of dielectric materials and an optimized combination of processes, it is possible to prepare figure 2 addressing electrodes with the structure shown and have as figure 1 The medium of the shown structure, the method mainly adopts the following steps:

[0028] S11, use printing, drying, exposure, development and sintering to complete the fabrication of address electrodes, wherein the width of the address electrodes is appropriately increased under the corresponding Y electrodes, to obtain the following: figure 2 The address electrodes 3 are shown.

[0029] S12 , forming dielectric layers with different thicknesses on the first portion 5 and the second portion 6 of the address electrode 3 . Here, the printing process is used, the first layer is s...

Abstract

The invention provides a plasma display panel and a lower substrate thereof, wherein the lower substrate comprises an addressing electrode and a medium arranged on the addressing electrode; the addressing electrode is provided with a first part and a second part; the first part corresponds to the position of a sustaining electrode of an upper substrate, and the second part corresponds to the position of a scanning electrode of the upper substrate; and the second part is wider than the first part. In the invention, the width of the addressing electrode of a part corresponding to a Y electrode is increased, and the widths of the addressing electrodes of other parts are reduced so as to improve the addressing efficiency and reduce the capacitance and the non-effective power consumption of the addressing electrodes.

Description

technical field [0001] The invention relates to the field of flat display screens, and more particularly, to a lower substrate of a plasma display panel and the plasma display panel. Background technique [0002] Plasma Display Panel (PDP for short) uses gas discharge to generate vacuum ultraviolet light (VUV), and the ultraviolet light excites three primary color phosphors to generate red, green and blue three primary color light, and then realizes it after space and time debugging. Image display. AC surface discharge plasma display screen, divided into front and rear substrates. The front substrate includes an ITO layer, and sustain electrodes (also called X electrodes) and scan electrodes (also called Y electrodes) arranged alternately on the ITO layer, and the X and Y electrodes are covered with a dielectric layer of a certain thickness, and then A layer of MgO thin film is deposited on the dielectric layer; the rear substrate includes the addressing electrode on the g...
