Description of the Invention (/) Field of the Invention The present invention relates to a plasma display. In particular, the present invention relates to the use of a horizontal separator in a discharge unit of a plasma display device to increase the coating area of the phosphor in the discharge unit and to expand the discharge formed between the two discharge sustaining electrodes. Range, reducing dark areas and improving luminous efficiency. BACKGROUND OF THE INVENTION The flattening of the panel of a display is a research trend of the display panel in recent years. Currently developed displays with flat display panels include: plasma display panel (PDP) 'liquid crystal display (LCD), and electroluminescent (EL) displays. The common feature of these displays is the data signal representing the display data, which is supplied from a drive circuit to several vertical address lines (or data bus lines), and several horizontal scanning lines are successively excited to display the display. The data is in a discharge cell located at the intersection between the address line and the scan line. Among many flat-panel displays, PDP is a new product that has attracted much attention in recent years. PDP is a large-scale flat-panel display that can be used as a wall-mounted TV for home and a monitor for a computer. According to the discharge mode, PDP can be divided into two types: direct current (DC) discharge and alternating current (AC) discharge. The two have different panel structures and driving methods. The biggest difference between the panel structure of AC-PDP and DC_PDP is the presence or absence of a dielectric layer on the outside of the discharge electrode. DC-PDP does not have such a dielectric layer. Due to the lack of protection of the dielectric layer, the electrodes are directly exposed to the sputtering of the plasma, and the phosphor is easily blackened, resulting in a short life. In addition, in order to prevent the discharge current from being too large, the DC-PDP must be designed with a resistor in each discharge cell to suppress the current. The resistance of these in-cell resistors is difficult to control in production. In addition, due to the memory effect accompanying the wall charge remnants, an auxiliary space for priming must be designed beside each discharge cell. Therefore, in general, the panel production of DC-PDP is more complicated and difficult than that of AC-PDP. 195P04, ADT-9815 This paper size is suitable for Chinese arsenic purine (('stain) / \ 4 specifications (2) 0/297 public Li)-;-^ ----- f ------ 1T ------ Γ Please read the notes on the back before filling in this page) A7 B7 V. Description of the invention (>) Difficulty has also led to the importance of AC-PDP in the development of commercial applications. However, there are still many problems in AC-PDP. The main problems are as follows: 1. Improvement of luminous efficiency: From the current 1 lm / w to more than 2 lm / w, the brightness ( brightness) is 500 nit (cd./m2) or more. And control power consumption within 300 watts. This can be done in many directions. For example, to find a better discharge cell structure, improve the electron emission coefficient of the electrode surface (MgO), find a better composition of the discharge gas, improve the quantum efficiency of the phosphor, and use a longer wavelength of ultraviolet light as the excitation light source to increase the visible light. The reflectivity of the rear plate and the transmittance of the front plate. As the size of the discharge cells shrinks, the need for improved brightness becomes more urgent. In addition, changing the driving method or improving the efficiency of the driving circuit system can also improve the overall luminous efficiency. When the brightness is increased, the improvement of the contrast degree becomes relatively easy. The current driving technology can already reduce the background chirp (generated during the ignition) to below Init, so it is only necessary to reduce the reflection of ambient light. The addition of the anti-reflection layer will hinder the light out of the panel, and it is necessary to increase the brightness of the display.
I 2、 降低成本： 目前PDP價格還相當高，每台42吋之售價在一百萬日圓上下，50 吋的PDP定價更高達兩百萬日圓以上，這不是一般家庭所能接受 的價位。未來PDP的價格設定以每吋一萬曰圓爲目標。這可由幾 方面著手，就製程的改善方面而言，須簡化製程，提升顯示器 之製作良率(yield ratio) 〇 MgO膜的蒸鍍、隔板(rib)的形成及螢光 體的塗佈等製程須作進一步之改進。製作顯示器之材料(如玻璃 基板等)的成本須降低。其次就驅動電路而言，須降低顯示器之 工作電壓，如此可降低驅動1C之成本。此外亦可改變顯示器之 驅動方式，以減少所需1C之數目。I 2. Reduce costs: At present, the price of PDP is still quite high. The price of each 42-inch PDP is around one million yen, and the price of 50-inch PDP is more than two million yen, which is not a price acceptable to ordinary families. In the future, the price of PDP will be set at 10,000 yen per inch. This can be done from several aspects. As far as the improvement of the process is concerned, it is necessary to simplify the process and improve the yield ratio of the display. The evaporation of the MgO film, the formation of the ribs, and the coating of the phosphor, etc. The process needs to be further improved. The cost of materials for the display (such as glass substrates) must be reduced. Secondly, as far as the driving circuit is concerned, the operating voltage of the display must be reduced, so that the cost of driving 1C can be reduced. In addition, the driving method of the display can be changed to reduce the number of 1C required.

At that time, a slender discharge tube was used as the discharge unit. In 1964, the display panel with the prototype of modern AC_PDP was designed by Dr. Slowttow of the University of Illinois. It uses nitrogen as the discharge gas. The principle of PDP is the application of gas under certain pressure, which can be easily released by an external electric field to become a conductor. During the discharge process, gas atoms or molecules will undergo the outer electronic energy level transition due to the impact of charged particles. Therefore, it will radiate photons of various wavelengths, including ultraviolet rays, which can be converted into the desired visible light through the conversion of phosphors. This is the light-emitting principle of color PDPs. After firing, the gas can be continuously discharged at a lower voltage. This is the so-called glow discharge area, and it is also the stable operating area of the PDP. If the voltage is too high, arcing (? Rcing) occurs, causing the electrode to burn out. The easiest discharge pressure is related to the distance between the discharge electrodes. There is a so-called Paschen curve relationship between the pressure between the discharge pressure and the electrode distance. _____195P04, ADT-9815__ £ The scale of this paper is suitable for China's family standard (1 (, NS) Λ4 (210X297 mm) 1. 1 mnnnnnnnn * 1TIn m (Please read the precautions on the back before filling this page) Hurry The ministry finalizes the BC.T elimination fr cooperation private seal?

Description of the Invention (Minutes) The wavelength and intensity of PDP light emission are determined by the type and pressure of the gas, and the intensity of the applied electric field. "Inert gas without chemical reactivity is the discharge gas most commonly used as a PDP." At present, PDP uses Ne-Xe mixture gas widely, and the air pressure is about 200 ~ 700 torr. Xe content generally does not exceed 10%, high pressure and brightness, but high discharge voltage. Xe gas discharge produces ultraviolet light at wavelengths of 147nm, 153nm, and 172nm. These are the excitation sources for the three primary color phosphors: red, green, and blue. At the highest Xe content, the intensity of long-wave UV light increases. Ne is added for the purpose of auxiliary discharge, because its metastable energy level helps Xe to dissipate. It is also possible to add a portion of He to reduce the intensity of the orange light emitted by Ne and improve the color purity of the panel. The Ne-Ar (0.5%) gas mixture commonly used in general fluorescent lamps has also recently been investigated to show that it can be used in PDPs to reduce the discharge voltage of PDPs and improve luminous efficiency. The surface discharge type AC-PDP has two electrodes for sustaining discharge, which are arranged on the same substrate, and the phosphor is coated on the other substrate, and the phosphor is less likely to be bombarded by charged particles. Therefore, the service life can be greatly improved. The first picture shows the structure of a conventional three-electrode surface-discharge type AC-PDP. Millions of discharge cells are sandwiched between two glass substrates. Each discharge cell contains the necessary electrodes, dielectric layer, discharge gas, and phosphor. One pixel consists of three discharge cells that are laterally adjacent and coated with phosphors that are converted into red, green, and blue light. Different discharge cells are separated by a separator. At present, the general design is to make the partitions only longitudinal strips, and not horizontal partitions. This has the advantage that large alignment errors can be tolerated when combining the front and rear substrates in the later process. However, the disadvantage is that letting two longitudinally adjacent discharge cells flow to each other will cause the problem of cross talk, which will cause the display color distortion and contrast to be reduced. The front substrate part has two electrodes in each discharge cell, which are the main electrodes for sustaining discharge light, and are divided into Y-electrode (scanning electrode) and X-electrode (common electrode). Each discharge sustaining electrode is composed of a wide discharge electrode and a thin bus electrode. The discharge electrode is generally made of transparent conductive plastic ITO. Use it to increase the discharge area and adjust the discharge interval. The bus electrode is usually silver with lower resistance or __195P04.

Description of the invention (矣) Copper. If you use silver, you can directly print the electrode pattern on the screen, or use exposure and development methods to obtain finer lines. The advantage of the silver electrode is that it has a higher resistance. Low. Yesterday, copper was usually plated with CrCuCr by sputtering, and then the electrode was made by yellow light method. Above the electrode is a transparent dielectric layer that can provide the necessary capacitance. The upper layer is the MgO layer. The low function function can emit electrons at a lower voltage, and it also has the function of protecting the bottom layer from ions from being sputtered. The front panel of NEC products also includes a 蒴 -shaped color filter that filters light. color filter (CCF), and stripe-like black stripes for anti-reflection, the purpose is to improve contrast and increase color purity .CCF is currently only used by NEC. Although this design can greatly improve the high contrast and color purity, it will sacrifice about 30% of the brightness at the same time. The address electrodes on the rear substrate can also be made of copper or silver. It can add an additional layer A white reflective dielectric layer. Then a separator. In addition to separating the discharge cells, the separator also supports the upper and lower substrates. The discharge sustaining electrodes of the surface-discharge type AC-PDP are located on the front substrate. The requirements for the high uniformity of the separator are not as high as those of the DC-PDP or the opposing AC-PDP. This is also one of the advantages of the surface discharge type. The method of manufacturing the separator is still controversial, and traditionally It is a direct screen printing method (the alignment must be accurate and it must be printed ten or more times). One method is to use the whole surface printing or coating method to make a layer of substrate, and then remove the unnecessary part by sandblasting. This is the more mature method at present. Sandblasting method is suitable for large-area and high-definition displays, but the production method of the method is more complicated and the cost of materials is higher. Other methods are called lift-off method. ) And stamping The former is to use a filling material such as a photoresist dry film to make parts other than the separator first, fill the partition plate into the mold, and then remove the filling material after drying. The latter is still in the development stage. Not practical. After the separator is completed, the phosphor is coated. This process requires the control of the shape and thickness of the phosphor. Currently, it is mostly screen-printed. For honeycomb materials, red is used. It is Υ203: E3 + or (Y, Gd) B03: E3 +, green is BaM2i9: Mn or ZnSi04: Mn, and blue light is BaZlMgMC ^ E3 '. Among them, the blue color has the fastest response, but it also has the most severe degradation during or during the thermal process. Green phosphor with afterglow maintenance ______ 195Ρ04.

Description of the invention (彡) The problem of long time (delayed response), currently Most of the users are about Hms (10% afterglow). This may drag the green tail when displaying high-speed animation. The fast-responding fluorescent zero is still in the trial phase. In terms of glass substrates, The material requirements vary depending on the process equipment, process conditions, and display design. Generally speaking, ordinary window glass materials (sodalime) can be used. However, if the processing temperature cannot be lowered or the display When high alignment accuracy is required in the design, a high-strain point glass substrate, such as Asahi's PD-200, which is still a high cost, must be used. Within about 10 ppm. In addition, special cooling methods must be adopted in the firing furnace to avoid Distortion of the plate due to uneven cooling shrinkage (such as square to trapezoidal). The front and back glass substrates should be annealed or stabilized before heat treatment to eliminate stress and promote stability of the size to reduce the subsequent thermal process. The resulting shrinkage deformation "After the front and back substrate manufacturing process is completed, the subsequent alignment and sealing processes are performed. The sealing is to use low melting point glass glue to bond the two substrates. The alignment requirements of the general AC type are not strict, but when When using dual scan or CCF structure like NEC, the alignment must be accurate. In addition, the shrinkage, deformation or warpage of the glass substrate will make alignment difficult. The substrate is sealed and evacuated. Purpose It is to exhaust the gas inside the display, and then charge it with discharge gas. To exhaust the display with micro discharge cell structure completely, it will take a long time, which will be a bottleneck during mass production. The latter process is in mass production method There is no consensus on the above, and many new ideas are still being tested. Three-electrode surface discharge AC-PDP is currently the most used driving method. This method of separating the address from the display period is called ADS (address display-period sqjaration). It was first adopted by Fujitsu a few years ago. Its electrode configuration can refer to the second figure, which is the same as the first figure The top view of the same structure in the figure. As shown in the second figure, each discharge cell has a discharge range (a) and a non-discharge range (b). The discharge range (such as the X! -Electrode and γ,-electrode The interval is the bright field range, not the discharge range (such as the distance between the Xr electrode and the Y2 electrode in the adjacent discharge cell) 195Ρ04, ADT-9815 ____ 6 NS) Λ4 specification (210 X 297 male chelate) --r --.----- C ------ order -------- line ',. (Please read the precautions on the back first (Fill in this page again) A7 B7 V. Description of Invention (7) This is the dark field range. -In general, in order to avoid the electric field's and plasmas of vertically adjacent discharge cells from interfering with each other and causing a malfunction in addressing, the design of the discharge range is designed to be smaller than the non-discharge range. As a result, the resolution and brightness are reduced. The too small discharge range also limits the line width of the two discharge sustaining electrodes (x_electrode and γ_electrode), which will result in a lower yjeld rate when fabricating the electrodes. The third figure reveals the input waveforms of three electrodes of a side-discharge AC-PDP and their timing relationships. There are four further phases during the addressing period. In the first and third stages, the pulses are turned off simultaneously and fully ('pulse') in the second stage, the pulses are turned on simultaneously and fully. The second and third stages seem to be repeated, but have their purpose. This action can make the wall charge of each discharge cell tend to: cause the write signal in the fourth stage to accurately light the selected Of the discharge unit. The length or number of pulses of the discharge sustaining period is directly proportional to the number of sub-pictures contained in a set filed. The fourth figure shows the sub-picture structure included in a television picture. It contains 60 frames per second. The number of bits that can be parsed at one time can be 6, 8, 10, or 12 bits, etc. "The greater the number of resolutions, the more colors can be displayed. The number of commonly used resolution bits is 8 bits, and each color has 256 shades of gray. The three primary colors of red, green, and blue can be combined into about 17 million colors. Although the resolution can have 256 color levels, for a discharge cell with only a vertical separator, the structure will cause light leakage problems in the vertical direction, which will lead to the disadvantage of reduced color level control. For example, in the case of a discharge cell with a vertical partition only, the gradation control will be reduced from 1/256 to 2 to 3/256 when the light leakage rate is assumed to be 1%.

Therefore, it is necessary to improve the discharge reaction speed by the appropriate structure of discharge cells and materials to shorten the scanning time. To maintain 60 frames per second, when the number of scanning electrodes exceeds about 500, it must be at the same time. There are two scanning electrodes on (switch on), and in order to distinguish them, the addressing electrodes can be cut into two sections, the so-called double scanning method. However, the addressing 1C ', which has to be doubled in this way, also increases the cost. At present, the driving circuit accounts for more than half of the cost of the PDP module.

Description of the invention (0 In terms of the structure of the PDP module and system, the requirement is to be thin, but it must still take into account issues such as heat dissipation and noise. PDPs have low luminous efficiency, which is in the hundreds Most of the watts of power are consumed as heat, so the heat dissipation design is more important than other displays. In addition, the prevention of electromagnetic interference _) and infrared (IR) is also important, and it may cause erroneous actions during remote control. PDP structure 'in order to avoid alignment difficulties', the structural design of the discharge cell is only a vertical separator', but it causes problems such as light leakage, low resolution, that is, low luminous intensity. In the old PDP structure, the electrode The configuration is limited, so there is a shortcoming of a small discharge range. Therefore, one of the main objectives of the present invention is to provide a plasma display with high luminous efficiency. And propose improvements in electrode design and fabrication. Furthermore, the luminous efficiency is further improved, the production yield is improved, and the production cost is reduced. The conventional plasma display device described in the invention has the disadvantage that two vertically adjacent discharge structures may leak light to each other due to the structure of the discharge unit. The discharge range covered by the two discharge sustaining electrodes is too small, resulting in too large a dark area. It is attributed to the shortcomings of the conventional plasma display structure that is the main cause of its low overall luminous efficiency. The purpose of the present invention is to provide An electric award display with an improved structure has greatly improved its luminous efficiency. According to the present invention, a lateral partition is added to a discharge cell, and the phosphor can increase the coating area of the lateral partition wall to improve the luminous intensity. It can avoid the leakage of light between two vertically adjacent discharge cells, and improve the control of color gradation. "With the addition of the horizontal separator, the discharge range between the two discharge sustaining electrodes can also be expanded, thereby reducing the dark area. To further improve the overall luminous efficiency "After adding a horizontal separator in the discharge cell, two adjacent discharge cells can share a common Electrodes to reduce the number of electrodes "The discharge sustaining electrode can also have a larger line width design to improve its production yield and thus reduce production costs. _____195P04, ADT-9815_8_ This paper advances; ΓνΓ) Λ4 specification (210X 297 cm) (please read the precautions on the back before filling out this page), 1T ½¾-Ministry of Standards and Technology Bureau β, χ Consumer Hehe News Agency A7 B7 V.

Description of the invention (/ p) The final decision of the Ministry of Economic Affairs OC.T disappeared in Hezhu. 5f.l The plasma display of the embodiment includes a display panel and a driving circuit (not shown below in the figure, to describe the structure of the plasma display display panel. As shown in the fifth figure, a front glass substrate and a rear There are f discharge cells sandwiched between a glass substrate (not shown). Each discharge cell is defined by an enclosed space separated by two vertical partitions and two horizontal partitions. All include a certain address electrode, a first discharge sustaining electrode (Y-electrode), a second discharge sustaining electrode (X-electrode), a dielectric layer (not shown), a protective layer 'a discharge gas (not shown) ) And a phosphor. Each discharge sustaining electrode is composed of a wide discharge electrode and a thin bus electrode. The discharge electrode is a transparent conductive The material is formed to increase the discharge area. The bus electrode is made of silver or copper. The sixth figure shows that before the front and rear glass substrates are sealed, the separator, the addressing electrode and the fluorescent system are formed behind On the glass substrate. First, the addressing electrode is formed on the rear glass substrate in a longitudinal direction, and then longitudinal and lateral partitions are formed on the rear glass substrate along the boundary of a predetermined discharge cell. The fluorescent system is coated in the longitudinal direction. On the enclosed area and the partition wall separated from the horizontal separator. The seventh picture shows that after the glass substrate is unsealed, the first discharge sustaining electrode and the second discharge sustaining electrode are formed on the glass substrate before sealing. On the front glass substrate. The first and second discharge sustaining electrodes are formed on the front glass substrate parallel to each other and extending in the lateral direction. Then, the dielectric layer is coated on the discharge sustaining electrode, and the protective layer is coated on On the dielectric layer, the discharge gas system is filled between the protective layer and the phosphor. The two discharge sustaining electrodes of the present invention are disposed on the same substrate (front glass substrate), and the phosphor is coated on another -A substrate ( Glass substrate), so that the phosphor is less likely to be bombarded by charged particles. Therefore, the service life can be greatly improved. "In a horizontal sequence of discharge cells, three adjacent and coated cells will be converted into red, green, The discharge cells of the blue light phosphors constitute one pixel. The discharge cells of the same vertical sequence are coated with phosphors of the same color. The addition of a horizontal separator can truly prevent the adjacent discharge cells from leaking light to each other. It can ensure the control of color gradation and improve the contrast. For example, for the 8-bit resolution preface, the color gradation control of the plasma display of the present invention can be surely controlled at 1/256 » Compared with the gradation control (2 ~ 3 / 2½), the image quality has been greatly improved.

In the discharge cells in the vertical sequence, the (2N-1) th discharge cell shares a second discharge with the 2Nth discharge cell. Sustaining electrodes, N is a natural number. All second discharge sustaining electrodes are connected in parallel. In addition to reducing the number of second discharge sustaining electrodes, the second discharge sustaining electrode can also have a larger line width design. , It can improve its production yield and reduce the production cost. As shown in Figure 5A, due to the addition of the lateral separator, the formation between the first discharge sustain electrode and the second discharge sustain electrode in each discharge cell The discharge range can be extended to more than one-half of the vertical spacing of the discharge cells, and can even cover the entire The vertical spacing of the discharge cells further eliminates dark areas and improves the luminous intensity. With the expansion of the discharge range, the first and second discharge sustaining electrodes can also have a larger line width design, which can improve their manufacturing yield. The structure of the conventional discharge cell has no transverse partition. In order to ensure the accuracy of addressing, the distance between the two discharge sustaining electrodes must be reduced to the distance between the electric fields of the two longitudinally adjacent discharge cells. The plasma does not interfere with each other. Fig. 5B shows that in the present invention, due to the addition of a horizontal barrier, there is no concern that the electric fields and electric waves of the adjacent adjacent discharge cells interfere with each other, and the accuracy of addressing is maintained after the discharge range is enlarged. In the present invention, after the horizontal separator is added to the discharge cell, in addition to the increased discharge area, the coating area of the light-emitting body in each discharge cell is increased by the wall area of the horizontal separator and the coating area of the phosphor. The increase of the luminous intensity can also be improved. "In summary, the improvement of the structure of the discharge cell and the electrode configuration of the present invention can increase the coating area of the phosphor to avoid light leakage and increase the discharge. Product, eliminating dark areas. In addition to the overall improvement in luminous efficiency, the gradation control, contrast, and image quality have been greatly improved.

Description of the invention (/ >) Generally, a 42-inch plasma display panel is designed. The lateral spacing is about 1080 // m, and the width of the partition is about 60 ~ 80ym. Because a pixel is composed of three discharge cells adjacent to each other (discharge cells coated with the three primary colors of red, green, and blue, respectively), the lateral spacing of a discharge cell is about 360 / zm, and its vertical spacing is about 1080 // m 〇 According to the conventional discharge cell structure (without horizontal partitions), the discharge range (ie, the bright area range) is mostly smaller than 540 // m, so it still has a dark area range greater than 540 ^ ηι. According to the present invention, after a horizontal separator is added to the discharge cell, the discharge range can be expanded to a size greater than 540 / zm, and even covers the entire vertical distance (10 ^) " m) of the k electric cell, so that the dark area is completely eliminate. In the conventional discharge cell structure, the line width of the discharge sustaining electrode is about 75 to 100 // m. In the present invention, the discharge sustaining electrode may have a large line width design margin, and its line width may be 100 to 150 // m on a 42-inch display panel. In order to further improve the image quality of the display, in the second embodiment of the present invention, an improvement is made to the arrangement of the phosphors of the adjacent discharge cells. In the discharge cells in the vertical sequence, the color order of the phosphors is not the same as the old way of adopting the same color, but the red, green and blue three-color staggered order. In this way, the phosphors of adjacent discharge cells are not in the same color system, the contrast between each other can be improved, and the overall resolution is also improved.
