Abstract
A front-baseplate structure of plasma display screen comprises a front-baseplate provided with a transparent electrode, a BUS electrode, a medium layer and an MgO protective layer, wherein, between the medium layer and the MgO protective layer are arranged one or more metal crystal layers. The crystal layers can absorb another part of ultraviolet light being away from the fluorescent powder and is excitated by the ultraviolet light to form excitons, and the excitons conduct ultraviolet light lasing through mutual collision or self-emitted radiation with the direction of part of the excitated ultraviolet light being toward the fluorescent powder to excitate the fluorescent powder, thereby improving the brightness of the plasma display screen.
Description
Technical field
The utility model belongs to the gas discharge technical field, is specifically related to a kind of structure that can improve the plasma discharge display screen prebasal plate of luminous efficiency.
Background technology
Plasma display panel (PDP) is that a kind of utilization is emitted the display that visible light comes display image by the plasma discharge excitated fluorescent powder.When applying voltage on the electrode that is arranged in the plasma display panel (PDP) discharge space, the rare gas between electrode produces plasma discharge and produces ultraviolet ray, the fluorescent material in the ultraviolet ray excited unit, and then show desired image.
This plasma display floater can be divided into once-through type and AC type according to the difference of discharge mechanism, in the direct current type plasma display panel, each electrode of forming plasma display panel is directly exposed in the gas blanket, because the plasma that gas discharge produces directly bombards electrode, make electrode damage easily, so mostly use the AC plasma display screen now, in order to improve the brightness of display screen, must increase voltage, come the activating fluorescent powder luminous to discharge more ultraviolet ray, because it is voltage is high more, also just high more to the requirement of Circuits System, cost is high more, and power consumption is also big more.But, the ultraviolet direction that gas discharge discharges be directive from all directions, therefore has only nearly half ultraviolet direction towards phosphor powder layer, in addition half be orientation substrate forward, therefore this part ultraviolet ray can the activating fluorescent powder, just visible light can be converted to yet, but also environmentally harmful ultra-violet radiation can be caused.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, provides a kind of noble gas discharge that can make full use of to produce the structure that ultraviolet ray improves the front substrate of plasma display screen of brightness.
For achieving the above object, the technical solution adopted in the utility model is: comprise the prebasal plate that is manufactured with transparency electrode, BUS electrode, dielectric layer and MgO protective layer, be provided with one or more layers of metallic crystal layer between dielectric layer and MgO protective layer.
The thickness of metallic crystal layer of the present utility model is 100～200nm; The metallic crystal layer is zinc oxide or zinc oxide and bitter earth alloy; The upper and lower surface of the upper surface of metallic crystal layer or metallic crystal layer also is provided with second crystallizing layer that thickness is 10～100nm.
The utility model is by forming crystallizing layer between prebasal plate protective layer and dielectric layer; this crystallizing layer can absorb the other part ultraviolet light of fluorescent material dorsad; utilize them to excite and self form exciton; exciton collides mutually or self radiation is carried out ultraviolet and swashed and penetrate; the ultraviolet direction of this part that inspires some towards fluorescent material; thereby also fluorescent material is excited, improved the brightness of plasma panel.

Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Embodiment 1; referring to Fig. 1; present embodiment comprises the prebasal plate 1 that is manufactured with transparency electrode 2, BUS electrode 3, dielectric layer 4 and MgO protective layer 6; be provided with the metallic crystal layer 5 that one deck zinc oxide or zinc oxide and bitter earth alloy are made between dielectric layer 4 and MgO protective layer 6, the thickness of this metallic crystal layer 5 is 100～200nm.
Be manufactured with address electrode 10 on the metacoxal plate 11; The metacoxal plate dielectric layer 9 that on address electrode 10, forms, barrier ribs is a barrier 7; Has certain thickness phosphor powder layer 8; Prebasal plate 1 and metacoxal plate 11 encapsulation have been constituted plasma panel.
Present embodiment utilizes crystallizing layer 5 under effect of electric field, perhaps under ultraviolet the exciting of certain intensity, certain wavelength, can discharge ultraviolet ray, therefore utilize the ultraviolet ray of sending once more that phosphor powder layer 8 is excited, make it send visible light, improved the brightness of plasma panel.
Present embodiment utilizes the sandwich structure of protective layer 6, crystallizing layer 5 and second crystallizing layer 12; under effect of electric field; perhaps in certain intensity; ultraviolet the exciting down of certain wavelength can discharge ultraviolet ray; utilize the ultraviolet ray of sending once more that phosphor powder layer 8 is excited; make it send visible light, improved the brightness of plasma panel.
This example is to have utilized crystallizing layer 6 and be arranged on the sandwich structure that second crystallizing layer 12 of crystallizing layer 6 both sides is constituted, this structure is in the outfield or under ultraviolet the exciting of certain intensity, can send the ultraviolet ray of certain wavelength, thereby fluorescent material is excited, emit visible light.
