A surface discharge type aperture mask style plasma display plate with novel electrode structure

Abstract

Unlike to current shadow mask plasma display panel or discharge plasma display panel, this invention comprises: a front and back substrates, the conductive shadow mask between substrates for support, a couple of scanning and maintenance electrodes on the front substrate, and the addressing electrode on another substrate to form the discharge unit with the mesh hole of shadow mask. This invention can reduce power consumption.

Description

technical field

[0001] The present invention relates to a flat TV display panel, in particular to a shadow mask plasma display panel, in particular to a surface discharge shadow mask plasma display panel with a new electrode structure. Background technique

[0002] The currently used shadow mask type plasma display panel mainly includes a front substrate, a rear substrate and a shadow mask. Starting from the glass substrate, the front substrate is the scanning electrode, the dielectric layer, and the protective layer formed on the surface of the dielectric layer; the rear substrate is starting from the glass substrate, and is the addressing electrode perpendicular to the scanning electrode, the dielectric layer, and the protective layer on the dielectric layer. The formed protective layer; the shadow mask sandwiched between the front and rear substrates is a thin metal mesh plate containing a mesh array processed from conductive materials (such as iron or its alloys). The a...

Embodiment 2

[0031] In the first embodiment above, the upper opening 13 of the grid hole 12 of the shadow mask 3 is hexagonal and arranged in a strip shape, and the first electrode pairs 5, 6 are arranged non-parallel to the discharge area of ​​the upper opening 13, and the connection distance The first electrode pairs 5 and 6 at the shortest points are arranged in parallel, constituting the second embodiment. The grid holes 12 arranged in stripes and the relationship between the first electrode pairs 5 and 6 and the upper opening 13 are shown in FIG. 4 .

[0032] The sealing process and display principle of the display panel are the same as those in the first embodiment.

Embodiment 3

[0034] In the above-mentioned first embodiment, the shadow mask grid holes 12 form the upper openings of polygonal structures such as elongated, rhombus, circular, hexagonal or octagonal structures, and the lower openings are elongated, and the center of the upper and lower openings is within Conditions on a straight line perpendicular to the surface of the shadow mask, the corresponding first electrode pairs 5, 6 are arranged similarly to the inner edge of the upper opening 13, and the grid holes 12 of the shadow mask can be arranged in strips according to the display resolution requirements Or arranged in a Chinese character, the schematic diagram of the relationship between the front plate electrode structure and the shadow mask holes is shown in Figure 5, which constitutes the third embodiment group of the present invention, and its working principle is the same as that of the first embodiment.

Embodiment 4

[0036] In the first, second, and third embodiments above, the monochrome phosphor powder 24 is coated on the inner wall of the shadow mask mesh hole 12 and the array formed by the surface part of the dielectric layer 11 of the rear substrate 2 corresponding to the lower opening 14, and filled with Appropriate working gas makes it generate ultraviolet light of corresponding wavelength to excite the ultraviolet phosphor to emit monochromatic visible light, thereby realizing image display, as shown in Figure 6, which constitutes the fourth embodiment group of the present invention, that is, the new electrode Structured monochrome surface-type shadow-mask plasma display panel.
