Embodiment Construction
[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0019] Such as Figure 1-3 shown.
[0020] A shadow mask type plasma display panel formed by phosphor powder inkjet method on the shadow mask, which includes a front plate 9, a rear plate 10 and a shadow mask 11 sandwiched between the front and rear plates. The front plate includes a front substrate glass substrate 1, an electrode group 2, a dielectric layer 3 and a protective film 4, the electrode group 2 is located between the glass substrate 1 and the dielectric layer 3, and the protective film 4 covers the surface of the dielectric layer 3 . The rear plate includes a rear substrate glass substrate 5 , an electrode group 6 , a dielectric layer 7 , and a protective film 8 . The electrode group 6 is located between the glass substrate 5 and the dielectric layer 7 , and the protective film 8 is located on the surface of the dielectric layer 7 . The s...

The invention discloses a shadow mask plasma display panel with an ink-jet formed fluorescent powder shadow mask, which belongs to the technical field of panel display and comprises a front panel (9), a rear panel (10) and a shadow mask (11) clamped between the front panel and the rear panel, wherein the front panel (9) consists of a front glass substrate (1), an electrode assembly (2), a dielectric layer (3) and a protective film (4); the rear panel (10) consists of a rear glass substrate (5), an electrode assembly (6), a dielectric layer (7) and a protective film (8); the shadow mask (11) is a sheet metal comprising an array of micropores (12); the inner walls of the micropores (12) are provided with fluorescent powder layers; and the shadow mask plasma display panel is characterized in that the fluorescent powder layers are coated in the micropores (12) by adopting ink-jet technology. The shadow mask plasma display panel solves the problems that the prior fluorescent powder forming technology has large manufacturing difficulty and poor display effect, does not need shadow mask or silk screen, and has the advantages of simple process, low cost and suitability for mass production.
Description
technical field [0001] The invention relates to a plasma display technology, in particular to a shadow mask plasma display panel formed by an inkjet method to form a phosphor layer, in particular to a shadow mask plasma display panel formed by an inkjet method of phosphor powder on a shadow mask body display panel. Background technique [0002] At present, the forming methods of the phosphor layer in the shadow mask type monochrome or color plasma display panel mainly include spraying method and screen printing method. [0003] The preparation of the phosphor layer on the shadow mask by the spraying method has many problems that need to be solved urgently. First, in the shadow mask type plasma display panel, phosphor powder needs to be coated in each micropore in the shadow mask. It is difficult to obtain a dense powder layer with a considerable thickness on the inner wall of the micropores of the shadow mask, and the spraying process is difficult. As the resolution incre...
