Description
Technical field
The present invention provides a kind of electrode structural designs of plasma scope, particularly a kind of electrode structure of plasma scope of less discharging gap (discharge gap).
Background technology
Plasma scope (plasma display panel is a kind ofly to produce luminous flat-panel screens by gas discharge PDP), its maximum characteristic be light, thin, easily maximize and the visual angle quite wide.The principle of luminosity of plasma scope is by the plasma generation ultraviolet light, is radiated on the fluorophor, sends visible light by fluorophor again.The generation efficient of plasma influences the luminous efficiency of plasma scope dearly.Promote the aforementioned arbitrary luminous step of putting forward, all can improve the luminous efficiency of plasma scope, but with present technology, the luminous efficiency of lifting fluorescent material itself also is not easy.On the other hand, the generation of increase ultraviolet light also can improve the luminous efficiency of plasma scope.The method that improves at present the ultraviolet light generation be except can changing the gas of being filled, outside, also can change the electrode structure of plasma scope.
Please refer to Fig. 1, Fig. 1 is the generalized section of traditional plasma scope 10.Traditional plasma scope 10 has two parallel substrates, comprise a prebasal plate (front substrate) 12 and one metacoxal plate (back substrate) 14, one ionized gas (not shown) is filled between prebasal plate 12 and the metacoxal plate 14, and two keep electrode (sustaining electrode) 16 and be arranged at prebasal plate 12 surfaces, and two keep and have a discharging gap (discharge gap) 17 between the electrode 16.Plasma scope 10 has more two auxiliary electrodes (bus electrode) the 18th, respectively with two keep the direction that electrode 16 is arranged in parallel and be arranged at two surfaces of keeping electrode 16, and a plurality of site selection electrodes (address electrode) 20, it is to be set in parallel in metacoxal plate 14 surfaces with the direction perpendicular with keeping electrode 16.
In addition; plasma scope 10 includes a dielectric layer 22 and is covered on the prebasal plate 12; one protective layer 24 is covered on the dielectric layer 22; a plurality of barrier ribs (rib) (not shown) is located on the metacoxal plate 14 in mode parallel to each other; be used for isolating two adjacent site selection electrodes 20; and one fluorescence coating 26 coat on each site selection electrodes 20 surface and the barrier rib sidewall, be used for producing redness, green or blue light.
Generally speaking, keeping electrode 16 is the transparency electrode (transparent electrode) that is made of the ITO material mostly, and visible light that can permeation parts also has bigger resistance value simultaneously.Auxiliary electrode 18 then is the opaque electrode that is made of chromium/copper/chromium (Cr/Cu/Cr) three-layer metal material, though its light transmission is relatively poor, yet but have good conductivity, therefore be designed to be stacked in and keep electrode 16 surfaces, to keep the purposes that electrode 16 conducts electricity as assisting.
See also Fig. 2, Fig. 2 is a Paschen curve chart.From wherein we can understand plasma scope 10 light voltage (firing voltage, V
f) for the relation of the product of interior inflation body pressure (P value) and discharge gap width (D value).When the PD product value equaled a certain constant value C, plasma scope 10 had the voltage of lighting V
fMinimum value, can reduce its required operating voltage.In general, in the present PDP manufacture craft, fixing lighting under the voltage conditions, in order to improve the chroma-luminance of display 10, the pressure P of inflation body (for example mist of xenon and neon) in needing usually to increase, as shown in Figure 3.Yet, by the curve of Fig. 2 as can be known,, will cause the increase of V value when the P value heals when big.If need keep original V
fValue just must relatively reduce the D value, that is dwindle discharging gap 17.Because the width of discharging gap 17 is the patterns by light shield (mask) definition photoresistance (not shown), and then the distance of electrode 16 is kept in decision, but be exposed the restriction of machine resolution and the material behavior of photoresistance own, mask pattern that can't spacing is less accurately shifts as on the film photoresistance, and form less discharging gap 17, the quality of display 10 is restricted.In addition, if use the liquid photoresistance of high-res to replace the dry film photoresistance, be to form less discharging gap.But liquid photoresistance because of material behavior preferable, so price is quite high.In addition, use liquid photoresistance, need the higher dust free room of cleanliness factor in the manufacturing process of plasma scope.Therefore, use liquid photoresistance will make the cost of manufacture of plasma scope improve many.
