    Improved PD Placement Structure
    The present invention relates to an electrode structure used in a flat panel display device, and more particularly, to reduce data writing time by improving an electrode arrangement structure used in a plasma display panel (hereinafter referred to as PDP). It relates to an electrode arrangement structure of PDPD.
    Recently, the development of technology to replace the CRT, which is the representative qualification of the display device which requires a large size and high operating voltage, is being actively conducted everywhere. As a substitute technology of the CRT, it is possible to reduce the thickness and realize high image quality. There are active display elements such as EL, LED, PDP, and passive display elements such as LCD, ECD, etc. The present invention relates to the improvement of a PDP display device which is one of such active elements.
    As is well known, a PDP is provided with at least three kinds of electrodes, that is, a sustain electrode, a write / hold electrode, and an addressing electrode, wherein the sustain electrode is provided with an alternating high voltage (+,-) provided externally. For example, by applying 180V to 300V) to each unit cell of the PDP, a function of maintaining discharge of a cell selected for display among a plurality of unit cells is performed, and the write / hold electrode is used to write data and The sustain electrode performs a function of maintaining a discharge of the selected cell together with the sustain electrode, and the addressing electrode performs a function of providing an address signal for addressing data to each unit cell.
    FIG. 2 is a schematic diagram of a typical electrode arrangement structure according to the related art. The conventional electrode arrangement structure scans an X electrode for generating wall charge and maintains a discharge, and scans a line to which digital R, G, and B signals are input and maintains a discharge. Y electrodes (Y1-Yn) and Z electrodes for addressing each data of each of the digitally separated R, G, and B.
    In addition, in the conventional electrode arrangement structure, the Z electrode for addressing each data of R, G, and B is substantially provided with one Z1 electrode provided on the upper side of the PDP panel A and the lower side of the PDP panel A. It has an electrode structure of one Z2 electrode.
    Therefore, the PDP display device having the conventional electrode arrangement structure as described above, the Z1 electrode of each of the R, G, B signals alternately provided in the R, G, B signal processing circuit, not shown, The drive addresses the 1R, 1B, 2G,----nR, nB, nG signals, and the G, R, B,----nG, nR, nB signals through the Z2 electrode.
    However, the prior art having the above-described electrode structure has a problem that the circuit configuration for address driving is difficult because the order of the R, G, and B signals input to the Z1 electrode and the Z2 electrode, which are the addressing electrodes, is irregular. .
    Furthermore, in the case of employing the conventional electrode structure in the PDP panel, assuming that the size of the PDP monitor is 640 × 480 as an example, 480 data writes must be performed on each address line, so that excessive time is unnecessary for data addressing. There is a problem. Therefore, when the conventional electrode structure having such an electrode arrangement is adopted in the PDP panel, there is a problem that only low gray scale processing (for example, approximately 64 gray scale processing) can be realized due to excessive addressing time.
    Accordingly, the present invention is to solve the above-mentioned problems of the prior art, by providing an addressing electrode for addressing each of the R, G, B signal data for each of the odd and even lines of the PDP panel effectively addressing time It is to provide an improved PD arrangement of the electrode arrangement that can be shortened.
    In order to achieve the above object, the present invention provides an X electrode for generating wall charges for a plurality of horizontal lines constituting each unit cell of a PDP panel and performing overall sustain, and selecting a line to which data is input; In the electrode arrangement structure of the PDP having a Y electrode for sustaining the horizontal line entirely, and a Z electrode for addressing each color signal data in line units of an image frame, the Z electrode for data addressing is: the PDP rear substrate; An odd line electrode pattern formed in an upper column of the first line to address odd line data of the image frame; And an even line electrode pattern formed in a lower row of the PDP back substrate, and having an even line electrode pattern for addressing even line data of the image frame, wherein the odd line electrode pattern and the even line electrode pattern are alternately arranged in a horizontal direction. Provided is an improved electrode arrangement structure of PDPD.

    The above and other objects and various advantages of the present invention will become more apparent from the preferred embodiments of the present invention described below with reference to the accompanying drawings by those skilled in the art.
    Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
    1 is a structural diagram of an electrode arrangement of an improved PD in accordance with a preferred embodiment of the present invention.
    As shown in the figure, the electrode structure of the present invention, when compared with the conventional electrode structure shown in Figure 2, the X electrode (holding electrode) for the generation of the wall charge and the discharge retention, digital R, G, Y electrodes (Y1-Yn) (write / hold electrodes) for scanning a line to which a B signal is input and maintaining a discharge, and a Z electrode (addressing) for data of each digitally separated R, G and B data. It can be regarded as similar in that it has an electrode), but an odd line electrode is formed in the upper column for writing the color signal data of the odd line, and an even line electrode is formed in the lower column for writing the color signal data of the even line. Therefore, the color signal data writing of odd lines and data writing of even lines of the PDP panel A are simultaneously implemented, which has the biggest technical characteristics different from the prior art. There were bars can be achieved for the purpose. Therefore, the following will mainly describe the arrangement structure of the addressing electrode that constitutes the greatest feature in the present invention.
    Referring to FIG. 1, in the electrode arrangement structure according to the present invention, two addressing electrodes Z for addressing respective data of R, G, and B which are separated through R, G, and B processing circuits, which are not shown, are provided as two. In other words, an electrode Z1 for odd-numbered color signal data addressing is provided above the PDP panel A, and an electrode Z2 for obtaining other even-line color signal data is provided below the PDP panel A. . The addressing electrodes Z1 and Z2 can form an electrode pattern by a thick film printing method as in the conventional method.
    In Fig. 1, in the electrode arrangement structure according to the present invention, the Z1 electrode is responsible for writing data on the odd-numbered line of the PDP front substrate, and the Z2 electrode is responsible for writing data on even-numbered lines of the PDP front substrate. That is, according to the electrode arrangement structure of the present invention, the electrode addressing for the image display is not sequentially performed in units of frames as in the conventional method, and the field concept, that is, one frame is the image data in odd lines and even lines It is divided and addressed simultaneously. Accordingly, a data writing speed approximately twice as fast as that of the conventional method of sequentially addressing frame image data may be obtained.
    On the other hand, the Z1 electrode for writing data on the odd-numbered line of the front substrate is R 1,1 , G 1,1 , B 1,1 , ---- R 1,640 , G 1,640 , B 1,640 signal data to the PDP panel ( The Z2 electrode which is inputted to each unit cell of A) and is responsible for data writing of even-numbered lines of the front substrate is R 2,1 , G 2,1 , B 2,1 , ---- R 2,640 , G 2,640 , B 2,640 signal data are input to each unit cell of the PDP panel A, respectively.
    On the other hand, in the electrode arrangement structure of the present invention, an even number of front substrates is provided on the electrodes R 1, x , G 1, x , B 1, x ,----which are responsible for data writing of odd-numbered lines of the PDP front substrate. Matching with the second line is realized by applying a material having a low dielectric constant without applying a phosphor to the electrode, that is, blocking the application of voltage so that plasma does not occur due to application of voltage. This eliminates the matching, even though the electrodes are responsible for writing the even-numbered lines, even with the odd-numbered lines. That is, in order to prevent data from being written due to the absence of phosphors on the electrodes, data writing occurs and sustain occurs to generate ultraviolet rays.
    Here, the use of a material having a low dielectric constant is intended to make the charge amount Q small as in the following formula.
    [Equation]
    C ∝ εS / d
    Q = CV
    In the above formula, S represents the area of the electrode, d represents the distance between the electrodes, ε represents the dielectric constant, C represents the charging capacity, and V represents the voltage. That is, as can be seen from the above equation, when the dielectric constant epsilon is small, the charge capacity C is small, and when the charge capacity C is small, the charge amount Q becomes small. At this time, as a material having a small dielectric constant epsilon, for example, air may be used. For this purpose, the electrode is left in the air without any dielectric material.
    As a result, by using this electrode structure, the odd line data and the even line data are simultaneously written without mismatching between adjacent lines (i.e., odd and even lines), thereby reducing the time required for data writing. You can cut it in half.
    As described above, according to the present invention, an addressing electrode for writing odd line color signal data of frame unit image data is formed in the upper column, and an addressing electrode for writing even line color signal data is formed in the lower column, respectively. By writing the odd line color signal data and the even line color signal data at the same time using the double electrode structure, the time required for data writing can be greatly reduced.
    In addition, by reducing the data writing time to each pixel, the gradation processing can be improved, or the luminance can be improved by lengthening the sustain (discharge sustain or discharge sustain) period.
