Embodiment 1

[0023] Such as Figure 1-4 shown.

[0024] An asymmetric shadow mask type plasma display panel includes a rear substrate 1, a front substrate 2, and a shadow mask 3, wherein the shadow mask 3 is located between the front and rear substrates 1 and 2. The rear substrate 1 is mainly composed of a rear substrate glass substrate 4, a first electrode 5, a dielectric layer 6, and a protective film 7, wherein the first electrode 5 (usually called a column electrode group or an address electrode group) is located at the rear On the substrate glass substrate 4, the dielectric layer 6 is covered on the first electrode 5, and the protective film 7 (magnesium oxide) is then covered on the dielectric layer 6; the front substrate 2 is mainly composed of the front substrate glass substrate 8, A second electrode 9, a dielectric layer 10, and a protective film 11 are formed, wherein the second electrode 9 (usually called a row electrode group or a scanning electrode group) is located on the lo...

Embodiment 2

[0026] In Embodiment 1, the lower surface of the shadow mask 3 in contact with the rear substrate 1 is formed at a position corresponding to the column electrode group 5 to a depth of 0.01d-0.9d (d is the thickness of the shadow mask 3, generally 0.1-1.0mm ), a through groove 13 with a width of 0.1 to 1.5 times the width of the column electrode, such as image 3 , the through groove 13 connects the adjacent grid holes in the column direction, and extends to the shadow mask frame. This has just formed the second embodiment provided by the present invention, and its operating principle is the same as the first embodiment.

Embodiment 3

[0028] In the first and second embodiments above, each grid hole, that is, the second electrode 9 in the discharge cell, is a parallel electrode group of multiple electrodes, or a vertical electrode is added on the parallel electrode group, and its length is 0.1 to 0.8 times The column length of the unit, such as Figure 5 , constitute the third embodiment group of the present invention.

Abstract

The present invention aims at the problems that the existing shadow mask type plasma display panel has small discharge space, short discharge path, small fluorescent powder coating area and thus low brightness and low luminous efficiency, and invents a device with higher brightness and luminous efficiency. An efficient asymmetric shadow mask type plasma display panel, which mainly includes front and rear substrates and a conductive shadow mask containing a grid hole array sandwiched between the front and rear substrates to support the front and rear substrates, each grid The holes vertically intersect the address electrodes and the scan electrodes to form basic discharge cells. The feature of the present invention is that the lower openings of the scanning electrodes and the grid holes of the conductive shadow mask deviate from the center of the discharge cells at the same time, and the offset directions of the two are opposite, thus prolonging the discharge path between the scanning electrodes and the addressing electrodes and increasing the amount of fluorescent powder. coating area, thereby improving the brightness and luminous efficiency of the display panel.

Description

technical field [0001] The present invention relates to a plasma display panel, in particular to a shadow mask type plasma display panel, in particular to an asymmetric shadow mask type plasma display panel.
