Abstract
The utility model relates to an AC plasma display screen, comprising a front glass plate and a back glass plate sealed with the front glass plate, wherein, the inner lateral face of the front glass plate is provided with a discharge electrode which forms a discharge unit composed of a Y electrode and two adjacent X electrodes at both sides of the Y electrode; so, process is simplified, cost is reduced, yield is increased, the discharge area of a display screen is enlarged, the light emitting brightness of the display screen is raised, and the performance of the display screen is improved.
Description
The utility model relates to a kind of display screen, particularly a kind of plasma display panel (PDP) that is used for information terminal demonstration and wall hung TV.
Present general once-through type plasma display panel (PDP), all adopt the surface discharge type structure, promptly preparation has sparking electrode (transparency electrode) on front glass panel, be manufactured with main electrode (metal electrode) on it again, and then on electrode surface, apply one deck dielectric layer, also preparation has one deck MgO diaphragm on dielectric layer; Then on the glass plate, addressing electrode, dielectric layer, barrier and phosphor powder layer are arranged then.The front and back glass plate that makes has promptly been made AC plasma display panel behind sealing-in, exhaust inflation ageing, display screen is equipped with the corresponding driving circuit could operate as normal.
Because the plasma display panel (PDP) complex process, operation is many, so rate of finished products is low, cost is difficult to reduce.The show electrode (sparking electrode+main electrode) of existing PDP display is arranged as follows on front glass panel: form a discharge cell by an X electrode and an adjacent Y electrode, discharge plasma promptly produces between this a pair of electrode, and region of discharge is that electrode is asked crack d
1In order to prevent that a discharge in the unit is crosstalked into adjacent cells, so bigger interval d should be arranged between two discharge cells
2General d
2/ d
1≈ 1.7~2.0.Under the situation that the resolution of substrate size and display screen is determined, discharging gap d
1Size also just correspondingly determine, thereby restricted the luminosity of display screen.
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, a kind of AC plasma display panel of three-electrode structure is provided, on its front glass panel without transparency electrode, thereby simplified technology, help reducing cost, improve rate of finished products, and this electrode structure has enlarged the region of discharge of display screen, help improving the luminosity of display screen, improved the performance of display screen.
The utility model sparking electrode is made up of Y electrode two X electrodes adjacent with its both sides, forms a discharge cell.When display screen was worked, its discharge can be that region of discharge is 2d in two gaps of two at Y electrode simultaneously
1Scope increases the luminosity of display screen; The adjacent electrode of two adjacent discharge cells all is the X electrode, and their current potentials are identical, thus crosstalking of adjacent cells discharge can not taken place, thereby the interval d between two discharge cells
2Can reduce, like this under the situation of same panel size, just for increasing d
1Leeway is provided, and d
1Increasing then, luminosity just can further increase.Because the region of discharge of kind electrode structure is big, thus can be without transparency electrode, thereby simplified the manufacturing process of front glass substrate greatly, and be convenient to improve rate of finished products, reduce cost.
Fig. 1 is a structure principle chart of the present utility model.
Fig. 2 is a discharge cell structure chart of the present utility model.
Below in conjunction with accompanying drawing structural principle of the present utility model is done detailed explanation.
With reference to Fig. 1, the utility model comprises that a front glass panel 1 reaches the back glass plate 6 of sealing-in with it, and the medial surface of front glass panel 1 disposes sparking electrode 2, sparking electrode 2 surface-coated one dielectric layer 4, configuration one deck MgO diaphragm 5 on the dielectric layer 4.Dispose addressing electrode 7 on the glass plate 6 of said back, apply a dielectric layer 8 on the addressing electrode 7, be provided with on the dielectric layer 8 in the gap of barrier 9, two barriers 9 and be coated with fluorescent material 3, wherein, (R), (G), (B) represent red, green and blue look fluorescent material respectively.
With reference to Fig. 2, sparking electrode 2 of the present utility model is made up of Y electrode two X electrodes adjacent with its both sides, forms a discharge cell, and the spacing that the Y electrode is adjacent between the X electrode is d
1, the spacing of two adjacent discharge cells is d
2
The utility model compared with prior art has following characteristics:
1. in the discharge cell of prior art, because d is only arranged1Gap discharge, bright for increasing Degree must increase glazed area, thus adopted transparency electrode, and only use transparency electrode, then The resistance of every strip electrode is too big, makes the display screen cisco unity malfunction, so adopted transparent electrical The combined electrode structure of the utmost point and metal electrode and usefulness. The preparation of transparency electrode relates to the film skill Art and photoetching process have bigger difficulty; And metal electrode is necessary when forming combination electrode With the transparency electrode strict counterpoint, further increased technology difficulty, the article on plasma display screen falls Low cost, improving yield rate has considerable influence.
And electrode structure of the present utility model, because of its region of discharge enlarges, thus without transparency electrode, only can reach higher brightness with metal electrode, thus simplified the manufacturing process of display screen, can reduce cost significantly, improve rate of finished products.
2. the three-electrode structure that the utility model proposes is at discharging gap d
1Under the constant situation, region of discharge can be increased to 2d
1The also corresponding increase of scope, transmission region is so the luminosity of display screen can obviously increase.
3. avoided the discharge between the neighboring discharge cells to crosstalk effectively owing in the three-electrode structure, so can not be subjected to d
2/ d
1The restriction of ≈ 1.7~2.0 provides big leeway for further expanding region of discharge.
