Description
Technical field
The present invention relates to the electrode structure of color plasma display panel, belong to technical field of flat panel display.
Background technology
Colour plasma display (Plasma Display Panel, be called for short PDP), be to utilize gas discharge to produce vacuum-ultraviolet light (VUV) to excite three primary colors fluorescent powder and produce red-green-blue light, the modulation through room and time realizes that coloured image shows then.
For surface discharge type color PDP display screen, mainly contain as lower electrode arrangement:
1. the bar shaped transparency electrode and (BUS) electrode structure that confluxes;
2.T the type transparency electrode and (BUS) electrode structure that confluxes;
3. grill-shaped electrode structure;
4. multi-electrode electrode structure.
Above-mentioned four kinds of structures all adopt the linear pattern electrode structure, and interelectrode machining area is little, make luminosity and luminous efficiency low.And in the above-mentioned electrode structure, bar shaped transparency electrode and conflux (BUS) electrode and T type transparency electrode and (BUS) electrode structure that confluxes have adopted the composite construction of transparency electrode and BUS electrode, technology cost height, and aligning accuracy requires height, and interelectrode electric capacity is big.
Summary of the invention
The objective of the invention is to propose a kind of surface discharge type color PDP display screen and keep electrode and scan electrode, be designed to the structure formed by arc-shaped electrode,, improve luminous efficiency and luminosity to reduce PDP technology cost with keeping electrode and scan electrode.
Purpose of the present invention can reach by following design:
A kind of plasma display panel (PDP) arc-shaped electrode structure, comprise and keep electrode and scan electrode, it is characterized in that in keeping electrode separate unit is made up of the short-circuiting electrode and the inner short-circuiting electrode at arc-shaped electrode and arc-shaped electrode two ends, each separate unit is formed by connecting by public electrode and keeps electrode; In scan electrode, separate unit is made up of the short-circuiting electrode at arc-shaped electrode and arc-shaped electrode two ends and inner short-circuiting electrode, and each separate unit is by the public electrode scan electrode that is formed by connecting; Or keep electrode and form by being the wavy multi sphere shape electrode that is connected with scan electrode.
Purpose of the present invention can also reach by following design:
Keeping electrode and scan electrode is made up of arc transparency electrode and bus electrode.
Above-mentioned arc-shaped electrode is many isocentric circular arc or with the arc circular arc.
The present invention has following advantage compared to existing technology:
1. owing to adopt the arc-shaped electrode structure, the effective area of keeping between electrode and scan electrode increases, and the luminosity of display screen and luminous efficiency are improved.
2. adopt multi sphere shape electrode structure, the ascending increase in the gap between sparking electrode can guarantee to realize big spacing gas discharge on the basis of not improving the display screen operating voltage, and the luminosity of display screen and luminous efficiency are improved.
3. adopt multi sphere shape electrode structure, the disposable making of electrode can guarantee the consistency of interelectrode gap, helps improving the performance of display screen.
4. adopt multi sphere shape electrode structure not require the making transparency electrode, not only saved interelectrode once accurate contraposition, and can save the technology cost.
5. owing to no transparency electrode, interelectrode electric capacity descends, and color PDP display screen power consumption is reduced.
Description of drawings
Fig. 1 is the schematic diagram of same arc-multi sphere shape electrode structure;
Fig. 2 is the schematic diagram of concentric-multi sphere shape electrode structure;
Fig. 3 is the schematic diagram of wave-multi sphere shape electrode structure.
Embodiment
Below in conjunction with accompanying drawing the present invention is further described, but is not limitation of the present invention.
Fig. 1 keeps the situation that electrode and the multi sphere electrode on the scan electrode are identical circular arc electrode, as shown in the figure, in keeping electrode, separate unit is made up of the short-circuiting electrode 3 and the inner short-circuiting electrode 4 at many identical arc-shaped electrodes 2 and arc-shaped electrode two ends, and each separate unit is formed by public electrode 1 connection and keeps electrode; Same, in scan electrode, separate unit is made up of the short-circuiting electrode 7 and the inner short-circuiting electrode 8 at identical arc-shaped electrode 6 and arc-shaped electrode two ends, and each separate unit forms scan electrode by public electrode 5 connections.In the said structure, keep electrode and scan electrode and can exchange, can not cause influence the work of color PDP display screen.
In multi sphere shape electrode structure shown in Figure 1, equidistantly arrange between arc and the arc, and spacing is d, arc-shaped electrode and the distance between the arc-shaped electrode in the scan electrode then kept in the electrode can be d, 2d, 3d, 4d, 5d---, after applying potential pulse between electrode, discharge will be preferentially begins between the electrode of a certain the most suitable discharge, to between other arc-shaped electrode, expand then, region of discharge is not only enlarged because adopt arc-shaped electrode, and the big interelectrode discharge of spacing have higher luminosity and luminous efficiency.
Figure 2 shows that the situation that adopts concentric circles arc electrode, the distance between arc and the arc changes with integral multiple along the arc diameter direction, can reach the effect that enlarges the region of discharge area and improve luminosity and luminous efficiency too.
As seen from Figure 1, Figure 2, adopt multi sphere shape electrode structure, can save transparency electrode and make reducing cost, and can improve luminosity and luminous efficiency.
There are the problem that must carry out accurate contraposition with site selection electrodes in Fig. 1, separate unit electrode structure shown in Figure 2, can adopt electrode structure as shown in Figure 3 for this reason.
In electrode structure shown in Figure 3, keep with scan electrode and form by being the wavy multi sphere shape electrode that is connected, when addressing discharge was carried out in arbitrary position of keeping electrode and scan electrode, discharged condition was all identical, thus site selection electrodes and keep and scan electrode between do not need accurate contraposition.Adopt electrode structure shown in Figure 3, the discharge process of inside, unit and Fig. 1, electrode structure shown in Figure 2 are identical.
Specific embodiments of the present invention is with structure shown in Figure 2 and be applied as example be illustrated in surface discharge type chromatic alternating-current PDP, if employing reflective structure, then will keep on the prebasal plate that electrode and scan electrode be produced on the color PDP display screen, can on electrode, make transparent medium and MgO layer according to designing requirement.Keeping on the site selection electrodes direction on the metacoxal plate and the prebasal plate is vertical with the scan electrode direction, can make dielectric layer, barrier and phosphor powder layer respectively according to designing requirement on the site selection electrodes, site selection electrodes and keep electrode and carry out carrying out sealing-in, exhaust after the accurate contraposition is made into the color PDP display screen after inflation, the sealed-off.In order to make the unit aperture opening ratio height of color PDP display screen, the present invention requires the electrode width should be meticulous as much as possible, electrode can adopt metal film electrode to do with the photoetching legal system, or adopt photosensitive silver-colored pulp material to do with the photoetching legal system, the color PDP display screen big to cell pitch also can adopt the precise silk screen print process to make.
Display screen type of drive of the present invention can adopt the type of drive of existing P DP display screen, also can be according to the present invention some characteristics of display screen, the designing optimal drive waveforms.
