Description
Technical field
What the present invention relates to is a kind of electrode structure of plasma scope technical field, specifically is the mutual border of a kind of length transparent electrode structure.
Background technology
Plasma scope (PDP) is divided into direct current plasma volumetric display (DC-PDP) and alternating-current plasma display (AC-PDP) two classes, and wherein AC-PDP is divided into two types of subtend discharge and surface discharges again.Surface discharge type AC-PDP is existing general plasma display apparatus, has following characteristics: each locations of pixels is determined that by the device electrode structure image is distortion not, clear display; Intrinsic digitlization characteristic more helps and being connected of digital signal; The visual angle is big, thickness is little, is fit to large scale display; Manufacture craft is easy to produce in batches, helps industry and forms.Surface discharge type AC-PDP adopts three-electrode structure, disposes pair of electrodes on the prebasal plate, and each electrode all is made up of ITO (indium tin oxide target) transparency electrode and metal bus electrode, these two electrodes is called respectively keeps electrode X and scan electrode Y; Addressing electrode A of configuration on the metacoxal plate.All cover one deck dielectric layer on the electrode of front-back baseboard, cover one deck mgo protection layer on the dielectric layer of prebasal plate, making is parallel to the barrier of addressing electrode on the metacoxal plate dielectric layer, and applies fluorescent material on metacoxal plate.With the front-back baseboard sealing-in, vacuumize at last, charge into the inert gas of certain pressure intensity.
Because each pixel of PDP all is an independently luminous tube, so power consumption is big; The main shortcoming of PDP another one is exactly that light efficiency is low, has only 1～2lm/W, and one of them reason that causes its low light efficiency is exactly that discharge space and machining area are little, makes that the efficient that produces xenon excitation state is lower.Along with the development of PDP, its resolution improves constantly, and makes machining area further reduce, and light efficiency and power consumption face more acid test.Especially in market competition fierce more today, facing to the impact more fierce to market of the more superior display of performances such as LED-LCD, PDP must pay close attention to and solve its lifting of performance in these areas.
As shown in Figure 1, be existing rectangle ITO electrode shape, 1 is ito transparent electrode, and 2 is bus electrode.Bus electrode is opaque, so in order to increase the aperture opening ratio of PDP, the bus electrode area is less, and width range 20～100 μ m.
Find through retrieval prior art, Hae-Yoon Jung, Hee-Woon Cheong etc. have proposed a kind of MEG (Multi ElectrodeGaps) transparent electrode structure in article " New electrode structure for reducing powerconsumption of PDPs " that IMID/IDMC/ASIADISPLAY ' 08DIGEST (69-72) delivers (reducing the new transparent electrode structure of PDP power consumption), this structure is introduced the discharge structure of setting out when increasing electrode spacing and improved light efficiency and reduce ignition voltage.But the integrally-built inhomogeneity that introducing brought of starting point, especially two electrode spacings than big-difference, can make discharge have uncertainty and an inhomogeneities.
Also find in the retrieval, G.Veronis and U.S.Inan is at JOURNAL OF APPLIED PHYSICS, VOLUME 92, NUMBER 9, and the electrode structure that the article of (4897-4903) delivering " Cell geometry designs for efficient plasmadisplay panels " (the effective method for designing of the three-diemsnional electrode of plasma panel) has proposed three-dimensional changes.But in order to increase discharge space, require transparency electrode thickness less,, influence actual effect so the structural design space on thickness of electrode is very little, and can bring the inconsistent of dielectric layer electric capacity.
Summary of the invention
The present invention is directed to the prior art above shortcomings, the mutual boundary plasma display of a kind of length transparent electrode structure is provided, keep electrode and scan electrode by the non-tablet structure, traditional parallel strip-like electrodes is changed into shape with long mutual discharge border, compare with conventional shape, changed Electric Field Distribution, easily produce the power line concentrated area, excite discharge, reduce driving voltage; Increase the length on mutual border between two electrodes simultaneously, increased machining area, thereby improved light efficiency.
The present invention is achieved by the following technical solutions, the present invention includes: two bus electrodes and lay respectively at transparency electrode under it, this transparency electrode and bus electrode a side on limit altogether are dull and stereotyped linear structure, and opposite side is waveform or the zigzag structure that shape is coincide.
Described scan electrode and keep the borderline phase coincidence of a lateral boundaries of the electrode transparency electrode corresponding with it.
The width of described bus electrode is 20～200 μ m.
The minimum spacing of the outer surface of described transparency electrode and the inner surface of bus electrode is 30～210 μ m, and maximum spacing is 170～720 μ m.
Vertical discharge spacing between described two transparency electrodes all equates in each position and is 50～150 μ m.
According to the asymmetric electrode structure in the mutual border of length of the present invention, the distance of transparency electrode and bus electrode is different and different with the locus, and introduced the shape of tip or Qu Duan, these make that all the shot point of induced discharge is easy to produce, and space electric field distributes that compare with the traditional electrode structure can be different, and long in addition mutual border makes machining area increase.Based on above analysis, can help the reduction of PDP discharge voltage and the raising of light efficiency.
