Abstract
This invention relates to a barrier wall structure of each discharging unit inside of an AC discharging plasma plane indicator, which is designed on the inside wall surface of the back base plate corresponding to the vertical-crossed position of X and Y electrodes on its front base plate. The said barrier wall has a rather thin wall at the position corresponding to the discharging unit to form a comparatively large discharging room and a thick wall at a place adjacent to the undischarging position, spreading steadily along the direction of the said non-discharging unit to form a smaller room as the gas channel of the two adjacent discharging units so as to effectively increase discharging efficiency.
Description
The present invention relates to the barrier wall structure of each discharge cell in a kind of AC discharge type electricity slurry flat-panel screens.
Press; at conventional AC discharge-type (being called for short the AC type) electricity slurry flat-panel screens (Plasma DisplayPanel; abbreviation PDP) in 10 the manufacturing technology; consult shown in Figure 1; mainly in two glass substrates 11; make different active layers on 12; again with the two peripheral involution; and in the discharge cell therebetween; special gas (as: the helium (He) that inclosure mixes according to certain proportion; neon (Ne); xenon (Ax) or argon (Ar); substrate towards the beholder in this structure is a prebasal plate 11; these prebasal plate 11 inboards are laid with a plurality of parallel transparency electrodes 111 in regular turn; auxiliary (bus) electrode 112; electric inducing layer 113 and protective layer 114; then be laid with a plurality of parallel addressing (data) electrodes 121 on the back of the body substrate 12 of its correspondence in regular turn; electric inducing layer 124; a plurality of barrier ribs that are arranged in parallel 122 and the phosphor body 123 that evenly is coated with; make and apply voltage these electrodes 111 at relevant position; 112; 121 o'clock; the electric inducing layer 113 of correspondence position; 124 will discharge in the formed corresponding discharge cell (Cell) 13 between adjacent barrier rib, make this phosphor body 123 induce corresponding color of light.
In conventional AC discharge-type electricity slurry flat-panel screens 10, electrode on this prebasal plate 11, generally utilize sputter and photoetch (Photolithography) or printing technology earlier, form a plurality of each intervals and horizontal transparency electrode 111 at these prebasal plate 11 inner surfaces, utilize evaporation (or sputter) and photoetch (Photolithograph) technology again, form this auxiliary electrode 112 on this transparency electrode 111, the line group that this auxiliary electrode 112 of mat reduces this transparency electrode 111 is anti-.The present invention in the following description, to represent two adjacent on this prebasal plate 11 parallel transparency electrodes 111 (containing auxiliary electrode 112) respectively with X electrode and Y electrode, this two electrode will with the addressing-electrode 121 on back of the body substrate 12 correspondence positions, form three electrodes, make when applying a voltage on these electrodes, make its electric inducing layer 113,124 discharge in corresponding discharge cell 13, make inclosure this mist wherein, because of discharge produces UV light, again by UV light, excite the phosphor body 123 of this discharge cell 13 places coating, order red (Red), green (Green), blue three look phosphor powders such as (Blue) can produce visible light, and and then show image.
In aforementioned conventional AC discharge type electricity slurry flat-panel screens 10, consult shown in Figure 2, these a plurality of barrier rib 122 that is arranged in parallel is located on this back of the body substrate 12, and these addressing-electrodes 121 are located at this electric inducing layer 124 bottoms, and arrange with these barrier rib 122 keeping parallelisms, make between adjacent barrier rib in the formed corresponding discharge cell 13, only the respective side wall surface of these barrier ribs and therebetween on three faces such as electric inducing layer 124 surfaces, can be coated with phosphor body 123, so will cause following shortcoming:
