Abstract
A flat display is composed of front base plate and back base plate. There is a gap between both. On the back base plate there are display area, the first slot walls at two or more side of said display area, and the second slot walls with a predefined space to the first one. Said the first and the second slot walls constitute a slot for filling the sealing glass in it. On the front base plate are slots for recepting said the first and the second slot walls.
Description
The invention provides a kind of flat-panel screens, particularly relate to a kind of flat-panel screens with sealing glass slot.
Development along with electronics and information industry, flat-panel screens (flat panel display, FPD) application and demand constantly enlarge, and plasma scope (plasma display panel is again quite to have development potentiality in each flat-panel screens PDP).General plasma scope is after substrate (front plate) all completes with back substrate (rear plate) in front, front substrate is inverted and cover on the back substrate, and then front substrate and back substrate involution (sealing) got up, to form the discharge cell (discharge cell) of sealing.Because the quality of involution can influence the follow-up manufacturing process yield that vacuumizes and pour into discharge gas, and can influence the isolation effect between each discharge cell, therefore be necessary further to improve the reliability and the quality of involution manufacturing process.
Please refer to Fig. 1 and Fig. 2, Fig. 1 and Fig. 2 are the front substrate 12 of existing plasma scope 10 and the synoptic diagram of the sealing method of back substrate 14.Existing plasma scope 10 includes a front substrate 12, and a back substrate 14 is located at the below of front substrate 12 abreast.Front substrate 12 is provided with a plurality of scan electrodes 16, a dielectric layer 17 and a magnesium oxide (MgO) layer 18, and back substrate 14 is provided with a viewing area 20 and a plurality of barrier rib (barrier rib) 22 is located within the viewing area 20.
As shown in Figure 1, the sealing method of existing plasma scope 10 is the viewing area 20 peripheral coating one sealing glass layers 24 of substrate 14 at first overleaf, carry out a heating manufacturing process then, make pulverous sealing glass layer 24 sintering together, thus the structure of temporary transient firm sealing glass layer 24.The front substrate that to temporarily fix subsequently 12 is put into high temperature furnace with back substrate 14, is heated to about 450 ℃ temperature, makes the low-melting glasses fusing in the sealing glass layer 24 and merges.As shown in Figure 2, existing sealing method utilizes anchor clamps 26 that front substrate 12 is closely pressed together on back substrate 14 in heating process, to guarantee that tight exists between front substrate 12 and the back substrate 14.After cooling, front substrate 12 can be completely fixed with back substrate 14 and tightening seal lumps together.
Because existing sealing method when coating sealing glass layer 24, causes the lack of uniformity of sealing glass layer 24 height quite easily, and powder coated path and the neither good control of diffusion phenomena of sealing glass.In case the height inequality of sealing glass layer 24 will make front substrate 12 and back substrate 14 involution fully, cause the phenomenon of leaking gas, even have a strong impact on the bond strength of two substrates.And the accurately control of the position of sealing glass layer 24, otherwise pollute viewing area 20 or other elements easily.In addition, anchor clamps 26 need utilize the barrier rib 22 in the viewing area 20 to exert pressure as supporting, yet this measure but causes the MgO layer 18 in the viewing area 20 to break easily, influences the display effect of plasma scope 10.
The object of the present invention is to provide a kind of plasma scope, to solve above-mentioned existing issue with sealing glass slot.
The object of the present invention is achieved like this, a kind of plasma scope promptly is provided, it includes: a front substrate, one back substrate, parallel relative with this front substrate, have a gap between this front substrate and the back substrate, and this back substrate is provided with a viewing area towards this front substrate surface; A plurality of barrier ribs (barrier rib) are located in the viewing area of this back substrate; One first guide groove wall is located in this gap, and is positioned at the both sides at least of the viewing area of this back substrate; One second guide groove wall is located in this gap, with this first guide groove wall preset distance of being separated by, to form a sealing glass slot with this first guide groove wall; And a sealing glass (sealing frit), be filled within this sealing glass slot, in order to this front substrate of involution and this back substrate.
The present invention also provides a kind of method for making of plasma scope, this plasma display includes a front substrate and a back substrate, this back substrate is provided with a viewing area towards this front substrate surface, and this method includes the following step: form a plurality of barrier ribs on the viewing area of this back substrate; Form one first guide groove wall and one second guide groove wall outside the viewing area of this back substrate, this first guide groove wall and this second guide groove wall preset distance of being separated by is to form a sealing glass slot; In this sealing glass slot, fill a sealing glass; And this front substrate is placed on this back substrate, carry out an involution manufacturing process, with together with this front substrate and this back substrate involution; Wherein this sealing glass slot can increase the uniformity coefficient of this sealing glass height, and controls the range of scatter of this sealing glass.
