Plasma display panel

The present invention relates to a plasma display panel, and more particularly to a shadow mask type plasma display panel, in particular to a surface discharge type shadow mask type plasma display panel, a surface discharge type of a finger-joined electrode structure. A shadow mask type plasma display panel and a surface discharge type shadow mask type plasma display panel of a novel electrode structure in which an electrode shape is matched with a shape of a shadow mask mesh hole. Background technique

The shadow mask type plasma display panel currently used mainly includes a front substrate, a rear substrate, and a shadow mask. The front substrate from the glass substrate is a scan electrode, a dielectric layer and a protective layer formed on the surface of the dielectric layer; the rear substrate is an address electrode perpendicular to the scan electrode from the glass substrate, and the dielectric layer and the dielectric layer are formed on the dielectric layer. The protective layer sandwiched between the front and rear substrates is a thin metal mesh plate comprising a mesh array processed from a conductive material such as iron or an alloy thereof. The front substrate, the shadow mask and the rear substrate are assembled and sealed, and then filled with a predetermined working gas, such as various inert gases, to form a shadow mask type plasma display panel. At present, the shadow mask type plasma display panel adopts the working principle of the opposite discharge, and its working principle is as follows: First, a high voltage narrow pulse or a ramp pulse erase signal is applied between the address electrode group and the scan electrode to erase the last discharge. Accumulated wall charge; then adding a high pulse addressing voltage to the scan electrode to select the row, while applying a data pulse of the row on the address electrode, the difference between the data pulse voltage amplitude and the scan voltage is higher than the scan electrode and the search The ignition voltage between the address electrodes controls the trigger discharge to form a wall charge distribution corresponding to the desired display information in the row; after the initial discharge of the full screen image is performed line by line, between the scan electrode group and the address electrode A sustain discharge pulse is applied to display the frame image. This cycle allows the image to be displayed frame by frame. For a color shadow mask type plasma display panel, the inner wall of the shadow mask is coated with three primary color phosphors, and the vacuum ultraviolet light generated by the gas discharge in each discharge unit excites different fluorescent materials to emit corresponding three primary colors of light. However, the above shadow mask type plasma display panel has the following problems: 1 Since the opposite type discharge structure is employed, the discharge space is small and the discharge path is short, so the discharge efficiency is low. 2 Since the area of the shadow mask hole wall on which the phosphor can be applied is small, the brightness is low. 3 Since the discharge area is far from the phosphor layer, the 147 nm vacuum ultraviolet light generated by the discharge has a large resonance absorption loss during the radiation to the phosphor, so the luminance and the luminous efficiency are low.

In summary, the conventional surface discharge type plasma display panel has the advantages of high luminous efficiency and high luminance, but the manufacturing process of the barrier structure is complicated, the cost is high, and the production yield is low. Summary of the invention

The object of the present invention is to solve the problems of the conventional shadow mask type plasma display panel using the opposite type discharge and the problem that the surface discharge type plasma display panel barrier is high in manufacturing cost and low in yield, and the invention has a high brightness, Surface discharge type shadow mask plasma display panel with high luminous efficiency and low power consumption, convenient manufacturing, surface discharge type shadow mask type plasma display panel with finger joint type electrode structure and an electrode shape and shadow mask grid A surface discharge type shadow mask plasma display panel of a novel electrode structure in which the hole shape is matched.

The second electrode 10, which is generally referred to as a column electrode group or an address electrode, is spatially perpendicular to the first electrode pair 5, 6 on the front substrate 1.

The shadow mask 3 is a conductive plate comprising an array of mesh holes 12 (which may be funnel-shaped, as shown in FIGS. 3 and 5), and the material thereof may be iron, iron-containing alloy, other metal alloy or surface-plated conductive material. The thickness of the non-metallic material of the film is 0. 1~1. 0mm, the area of the upper opening 13 of the mesh hole 12 opposite to the front substrate 1 is 10~ of the area of the lower opening 14 opposite to the rear substrate 2. 20 times, the opening width 15 of each mesh hole 12 is 1 to 4 times the width of the lower opening 16; the centers of the upper opening 13 and the lower opening 14 are on the same line in a direction perpendicular to the surface of the shadow mask. The first electrode pairs 5, 6 are arranged in parallel, corresponding to the surface position in the upper opening 13 of the mesh hole 12 of the shadow mask 3, and the second electrode 10 corresponds to the lower opening 14 of the mesh hole 12 of the shadow mask 3, 5〜倍倍, the electrode of the first electrode pair 5, 6, the lower opening width 16 of each of the mesh holes 12 is 1 to 2 times the width 17 of the second electrode 10, the upper opening length 19 is 1. 5~2 times the length of the lower opening 18 The width of the upper opening 19 is 5 to 20 times the electrode width 20 of the first electrode pair 5, 6, and the upper opening length 20 is 1.25 to 5 times the parallel spacing 21, each of the mesh holes 12 and the first The electrode pairs 5, 6 and the second electrode 10 intersect perpendicularly. as shown in picture 2.

The shadow mask 3, the first electrode pairs 5, 6 covering the dielectric layer 7 and the protective layer 8, and the second electrode 10 covered with the dielectric layer 11 form a dielectric barrier type AC surface discharge type basic unit. The sealing frame 22 made of the low-melting glass around the front substrate 1, the shadow mask 3, and the rear substrate 2 is hermetically sealed, and an exhaust pipe 23 is disposed outside the display region and in the sealing frame 22, and the exhaust pipe is passed through the exhaust pipe. In connection with the vacuum system, the above device can be vacuum degassed and filled with a certain working gas of a certain pressure and then sealed off from the vacuum system, which forms the plasma display panel provided by the present invention.

The working principle of the plasma display panel is as follows: A positive pulse Va is applied to the address electrode 10, in accordance with a signal for displaying an image, a negative pulse Vs is applied to the scan electrode 6, and a discharge is first generated at the address electrode 10 and the scan electrode 6, accumulating. Maintaining the wall charge required for discharge while keeping the cell in a lit state, applying a negative sustain pulse Vs to the sustain electrode 5, and the lit discharge cell maintains the lighting state under the action of the wall charge and the sustain pulse until The erase pulse comes. There are various ways to erase the discharge cells, and the purpose is to eliminate the wall charges that have existed in the discharge cells, so that they are turned from the lighting state to the extinguishing state under the action of the sustain pulse. If a narrow pulse erase is used, between the two discharges, a positive narrow erase pulse (a pulse width of about 1 microsecond) is applied to the scan electrode 6, which causes the wall charge generated by the discharge and the original wall charge generation. And, thereby causing the discharge unit to be extinguished. Applying different timings of high voltage pulses constitutes a different driving method. The plasma display panel of the present invention may employ a subfield driving method of addressing and display separation (ADS), or an alternating surface illumination (ALIS) driving method. For example, using the ADS subfield driving method, in the preparation period, the three electrodes of the discharge cell at the beginning (electrode 5, 6, 10) are all zero. A full-screen write pulse of amplitude V _XW (V _{XW is} much larger than the ignition voltage V _rxy between the electrodes 5 and 6) is applied to the sustain electrode 5, so that all cells on the screen are in the same state, that is, extinguished, and applied on the electrode 10 The pulse V _OT (V _OT is approximately V /2) causes the address electrode 10 to have substantially no wall charge accumulation. Entering the address period, the electrode 5 is applied with a voltage V _x ; the scanning electrode 6 is sequentially scanned, and the unscanned electrode 6 is added _ V _S ,, and the scanned electrode 6 is _V _{y; at the} same time, the address pulse v _a is added to the electrode 10 corresponding to the lighting, and the ov is added if the brightness is not required. First, discharge is performed between the electrode 10 and the electrode 6, causing discharge at the electrode 5 and the electrode 6, while accumulating wall charges. For a unit that does not need to be lit, since there is no address pulse, no discharge is generated, and no wall charge is generated. accumulation in the sustain period, the address electrodes 10 plus V _aw, plus half weeks 0V electrode 5, electrodes 6 applied sustain pulse V _s, the next half plus electrode 5 V _s, 0V electrode 6 applied sustain pulse, wall charges role in , the sustain discharge is always going on, and the discharge unit is lit Until it needs to be erased, the display panel is scanned line by line to complete the display of the entire frame image. Usually one frame of image is divided into several subfields, each subfield has a preparation period, an address period and a maintenance period. Moreover, the time ratio of the sustain period of each subfield is different to realize image gradation, and if 8 subfields are used, image display of 256 gradations can be realized.
