Background technology
In large scale and large-area display device, plasma display system (PDP:Plasma DisplayPanel) is a kind of novel display device of very potentialization.Existing plasma display system need lean on very large trigger voltage the ionized gas in it could be converted to can be for the plasma that back and forth drives, high voltage startup not only can need to use expensive driving and control element, and causes the shortening in the serviceable life of the damage of element and element easily.Therefore the trigger voltage that how to reduce plasma display system is a problem of current research.
With reference to Fig. 1.Fig. 1 is the sectional view of known plasma display system 10.Plasma display system 10 includes the first parallel substrate 12 and second substrate 18, and ionized gas 27 is filled between substrate 12 and 18, one first electrode, 26, one second electrodes 28 and a third electrode 20.Wherein first electrode 26 is parallel with second electrode 28 and is alternately arranged on first substrate 12, and third electrode 20 is to be arranged on second substrate 18 with the perpendicular mode of first electrode 26 and second electrode 28.Plasma display system 10 also includes a dielectric substance layer 14 and is covered on first substrate 12; one protective seam 16 is overlying on the dielectric substance layer 14; one fluorescence phosphorus layer 22 is located at and is used for producing fluorescence on the third electrode 20, and a protection wall 24 is located at and is used for isolating two adjacent fluorescence phosphorus layers 22 on the third electrode 20.
Third electrode 20 is projected to the zone that is included by first electrode 26 and second electrode, 28 formed planes and forms a display unit 30.After first electrode 26 and 28 at second electrode applied the trigger voltage of a high pressure, the field effect that first electrode 26 and second electrode are 28 can make the ionized gas 27 on it produce the electronics dissociations and form space charge.After producing space charge, third electrode 20 can be used to act on mutually with first electrode 26 or second electrode 28 and produce plasma, and determine wall electric charge (wall charge) density that produced in the display unit 30 whether can be greatly to lighting plasma, this wall electric density is to make display unit 30 be kept bright state (on) or become the not main key of bright state (off).If need not keep bright state, then the space charge in the display unit 30 can be reduced into normal ionized gas 27 (non-free state) in a short period of time.After decision keeps bright state, first electrode 26 and second electrode 28 can be used to back and forth to drive in the display unit 30 plasmas so that its continued send ultraviolet ray, and ultraviolet ray can make it send fluorescence after injecting fluorescence phosphorus layer 22, and 12 users just can see the light that display unit 30 is sent via transparent substrate.
First electrode 26 and second electrode 28 all are by chromium-copper chromium (CrCuCr) the opaque lead 261,281 that material constituted and 262,282 compositions of transparent lead of being made of the ITO material.But chromium-copper chromium material has good electric conductivity is light tight, but but then the visible light resistance value of permeation parts is bigger for the ITO material.Because the ITO material distance dependent that the size of the trigger voltage of display unit 30 and first electrode 26 and second electrode are 28, the transparent lead 262 that is constituted by the ITO material, though the visible light and the resistance value of 282 meeting absorption portion are bigger, but it can be used to shorten the distance of 28 at first electrode 26 and second electrode, to reduce the trigger voltage of display unit 30.
Though the trigger voltage that employed first electrode 26 that is made of chromium-copper chromium and ITO material of known plasma display system 10 and second electrode 28 can reduce display unit 30, but the transparent lead 262 that the ITO material is constituted, 282 can absorption portion visible light and fluoroscopic brightness is reduced, and its high resistance can produce bigger loss.
