Definitions

  • the present invention relates to plasma display panels (PDPs) and more particularly to a structure of discharge cells between barrier walls of alternating current discharge type PDP with improved characteristics.
  • FIG. 1 A manufacturing process of a conventional alternating current discharge type plasma display panel (PDP) 10 is shown in FIG. 1. First, two different activation layers are formed on glass substrates 11 and 12 respectively. Then seal the peripheries thereof. A mixed gas consisting of helium (He), neon (Ne), and xenon (Xe) (or argon (Ar)) having a predetermined mixing volume ratio is stored in a discharge space therein. A front substrate 11 is defined as one that facing viewers. A plurality of parallel transparent electrodes 111, a plurality of bus electrodes 112, a dielectric layer 13, and a protective layer 14 are formed from the front substrate 11 inwardly.
  • He helium
  • Xe xenon
  • Ar argon
  • a plurality of parallel data electrodes 121, a dielectric layer 124, a plurality of parallel spacer walls 122, and a uniform phosphor layer 123 are formed.
  • dielectric layers 113 and 124 will discharge on discharge cell 13 formed by adjacent barrier walls 122.
  • a ray having a desired color is emitted from phosphor layer 123.
  • a plurality of parallel transparent electrodes 111 are formed on inner surface of front substrate 11 by sputtering and photolithography (or printing). Then a plurality of bus electrodes 112 are formed on the transparent electrodes 111 by plating (or sputtering) and photolithography. The line impedance of the transparent electrodes 111 may be reduced by the provision of bus electrodes 112.
  • two adjacent transparent electrodes 111 (including bus electrodes 112) on the front substrate 11 are represented by X electrode and Y electrode respectively.
  • a triple electrode is formed by X electrode, Y electrode and corresponding data electrode 121 on the rear substrate 12.
  • dielectric layers 113 and 124 When a voltage is applied on the triple electrode, dielectric layers 113 and 124 will discharge on discharge cell 13 formed by adjacent spacer walls 122. Hence, UV rays are emitted from the mixed gas stored therein. And in turn, phosphor layer 123 in discharge cell 13 is excited by the UV rays. As an end, a visible light is generated by red, green and blue phosphor layers, resulting in an image showing.
  • a plurality of parallel barrier walls 122 are provided on back substrate 12.
  • a plurality of parallel data electrodes 121 are provided on the underside of dielectric layer 124. Barrier walls 122 and data electrodes 121 are alternate, while barrier walls 122 are atop data electrodes 121.
  • a discharge cell 13 is formed between two adjacent barrier walls 122.
  • a phosphor layer 123 is coated on discharge cell 13, opposite walls of barrier wall 122, and dielectric layer 124 respectively.
  • a number of proposals regarding the structure of barrier wall have been submitted by PDP designers and manufacturers for solving above drawbacks.
  • Pioneer Company Japan discloses a waffle-like barrier wall 622 as shown in FIG. 6. Phosphor layer is coated on top, bottom, left, right, and underside of discharge cell respectively. Hence, coating area of phosphor layers is increased, resulting in an increase of emissivity.
  • discharge cell is enclosed for eliminating the undesired discharge of non-discharge region. However, such enclosed discharge cell may increase difficulty of vacuum and gas filling.
  • Another design is disclosed by Fujitsu Company (Japan) wherein barrier wall 722 has a meander rib structure as shown in FIG. 7. Such structure can increase the coating area to a maximum.
  • alternating current discharge type plasma display panel PDP
  • a plurality of parallel barrier walls formed on top surface of a back substrate of the PDP, the barrier walls being disposed corresponding to cross-points of X electrodes and Y electrodes on a front substrate the PDP, a structure comprising a plurality of discharge cells between the adjacent barrier walls having smaller width corresponding to the X and Y electrodes for forming a large first space, a plurality of non-discharge cells each between the adjacent discharge cells for forming a small second space served as a gas channel between the adjacent discharge cells, and a junction having a predetermined shape between one discharge cell and the adjacent non-discharge cell, whereby energy released from a gas discharge in the discharge cells is concentrated within the discharge cells for increasing discharge efficiency, emissivity, avoiding undesired gas discharge, and achieving a smooth vacuum and gas filling during the manufacturing process of PDP.
  • a back substrate 31 and other associated elements of alternating current discharge type PDP in accordance with the invention.
  • a plurality of parallel data electrodes 311 are formed on back substrate 31.
  • a dielectric layer 33 is formed on data electrodes 311.
  • a plurality of parallel barrier walls 34 are formed on dielectric layer 33. Barrier walls 34 and data electrodes 311 are alternate, while barrier walls 122 are atop data electrodes 311.
  • a plurality of parallel transparent electrodes 321 each including an bus electrode 322 (e.g., X electrode or Y electrode) are formed.
  • a dielectric layer 33 is formed on the electrodes.
  • a protective layer 35 is printed on dielectric layer 33. Further, secure back substrate and front substrate together.
  • Data electrodes 311 on back substrate 31 and transparent electrodes 321 on front substrate 32 are disposed horizontally and vertically on PDP respectively. In other words, data electrodes 311 and transparent electrodes 321 are perpendicular each other, thus forming a plurality of discharge cells 41 therein.
  • a plurality of parallel barrier walls 34 are disposed corresponding to cross-points of X electrodes and Y electrodes on front substrate 32.
  • a plurality of discharge cells 41 are formed in wider areas between two adjacent barrier walls 34 corresponding to X electrodes and Y electrodes. Note that such wider areas (i.e., the width of barrier wall 34 is relative narrow) may increase discharge space of discharge cells 41 and emissivity accordingly.
  • the width of barrier wall 34 is increased from discharge cell 41 to non-discharge cell 42, i.e., the space of non-discharge cell 42 is small so as to serve as a gas channel between two adjacent discharge cells 41. This may concentrate energy released from gas discharge in discharge cells 41 within discharge cells 41 for increasing discharge efficiency, emissivity, avoiding undesired gas discharge, and achieving a smooth vacuum and gas filling during the manufacturing process of PDP.
  • the width of barrier wall 34 is relative narrow at the position abutted discharge cell 41. Further, the width of barrier wall 34 is increased in a predetermined gradient from discharge cell 41 to non-discharge cell 42, i.e., the space of non-discharge cell 42 served as a gas channel between two adjacent discharge cells 41. Hence, it may increase opening of discharge cell. Also, the number of surface with phosphor layers coated is increased from typical three to seven. As a result, the coated area of phosphor layer is increased significantly and the emissivity of PDP is also improved.
  • the width of barrier wall 34 at the position abutted discharge cell 41 is increased in one of a plurality of predetermined gradients from discharge cell 41 to non-discharge cell 42, i.e., the space of non-discharge cell is small. Further, only one such non-discharge cell is reserved as a gas channel between two adjacent discharge cells 41.
  • the width of barrier wall 34 at the position abutted discharge cell 41 is increased in one of a plurality of predetermined arcs from discharge cell 41 to non-discharge cell 42, i.e., the space of non-discharge cell is small. Further, only one such non-discharge cell is reserved as a gas channel between two adjacent discharge cells 41.
  • the width of one of plurality of parallel barrier walls 34 is relative wide at the position abutted non-discharge cell 42.
  • the structural strength of barrier walls is greatly enhanced.
  • the width of barrier wall 34 is relative narrow at the position abutted discharge cell 41.
  • it may increase discharge space, avoid undesired gas discharge, and increase drive voltage in operation.
  • such increase of width of barrier wall 34 abutted non-discharge cell 42 may increase adhesion of dry photo-resist mold in the sputtering due to the increase of adhesive area of dry photo-resist mold. As a result, abnormal peeling of dry photo-resist mold is avoided in the sputtering and yield is increased significantly.
