等离子显示器plasma display

技术领域technical field

本发明涉及一种等离子显示器(plasma display panel，PDP)，具体地说，涉及一种寻址电极位于前基板的等离子显示器。The present invention relates to a plasma display (plasma display panel, PDP), in particular to a plasma display with address electrodes located on the front substrate.

背景技术Background technique

等离子显示器(plasma display panel，PDP)是一种藉助于气体放电发光的平面显示器，其最大的特色是轻、薄、易大型化且视角相当广。等离子显示器的发光原理是靠等离子产生紫外光照射在荧光体上，再由荧光体发出可见光。Plasma display panel (PDP) is a flat panel display that emits light by gas discharge. Its biggest feature is light, thin, easy to enlarge and wide viewing angle. The light emitting principle of plasma display is to irradiate the fluorescent body with ultraviolet light generated by plasma, and then the fluorescent body emits visible light.

请参考图1与图2，图1与图2分别为现有的等离子显示器10的横剖面示意图与纵剖面示意图。如图1与图2所示，现有的等离子显示器10具有二平行基板，包括一前基板(front substrate)12以及一后基板(backsubstrate)14；一填充于前基板12与后基板14之间的电离气体(未显示)，用来产生紫外线；以及设置于前基板12表面，作为放电之用的多对彼此平行的维持电极(sustain electrode)16。前基板12上还包括多条辅助电极(buselectrode)18，分别电性连接于各维持电极16上；一第一介电层22；以及一保护层24，覆盖于第一介电层22上，用来保护电极，同时产生放电电子。Please refer to FIG. 1 and FIG. 2 . FIG. 1 and FIG. 2 are respectively a cross-sectional schematic diagram and a vertical cross-sectional schematic diagram of aconventional plasma display 10 . As shown in Figure 1 and Figure 2,existing plasma display 10 has two parallel substrates, comprises a front substrate (front substrate) 12 and a rear substrate (backsubstrate) 14; An ionized gas (not shown) is used to generate ultraviolet rays; and a plurality of pairs of sustain electrodes (sustain electrode) 16 parallel to each other are arranged on the surface of thefront substrate 12 for discharging. Thefront substrate 12 also includes a plurality of auxiliary electrodes (buselectrode) 18, which are respectively electrically connected to thesustain electrodes 16; a firstdielectric layer 22; and aprotection layer 24, covering the firstdielectric layer 22, Used to protect the electrodes while generating discharge electrons.

等离子显示器10的后基板14上则包括多条寻址电极(addresselectrode)20，其方向与维持电极16垂直；多个阻隔壁(rib)26(图1中未显示)，其方向与寻址电极20平行，且任相邻的两阻隔壁26与其上方相对应的两维持电极16形成一放电单元(discharge cell)，作为发光之用；一第二介电层28，覆盖于寻址电极20表面；以及一荧光层30，涂布于第二介电层28表面以及阻隔壁26的侧壁表面上，用来产生红色、绿色或是蓝色的光线。Then comprise a plurality of address electrodes (address electrodes) 20 on therear substrate 14 ofplasma display 10, its direction is perpendicular to sustainingelectrodes 16; 20 are parallel, and any adjacent twobarrier ribs 26 form a discharge cell (discharge cell) with the corresponding twosustain electrodes 16 above them, as the usefulness of light emission; a seconddielectric layer 28 covers theaddress electrode 20 surface; and Afluorescent layer 30 is coated on the surface of the seconddielectric layer 28 and the sidewall surface of thebarrier rib 26 for generating red, green or blue light.

一般而言，维持电极16大多是由氧化铟锡(ITO)或氧化锡(SnO₂)材料构成的透明电极(transparent electrode)，以透过大部分的可见光。然而，因其具有较大的电阻值，因此需要电连接一导电性能好的辅助电极18来帮助导电。辅助电极18一般是由铬/铜/铬(Cr/Cu/Cr)三层金属材料构成的不透明电极，其透光性虽然较差，却具有优良的导电性，因此被设计成叠置于维持电极16表面上，以作为辅助维持电极16导电并引发放电之用。而设在后基板14上的寻址电极20则由如银或铝等金属构成，用作写入数据之用。Generally speaking, thesustain electrode 16 is mostly a transparent electrode made of indium tin oxide (ITO) or tin oxide (SnO₂ ) to transmit most of the visible light. However, because of its relatively high resistance, it is necessary to be electrically connected to anauxiliary electrode 18 with good electrical conductivity to facilitate electrical conduction.Auxiliary electrode 18 is generally an opaque electrode composed of chromium/copper/chromium (Cr/Cu/Cr) three-layer metal material. Although its light transmission is poor, it has excellent electrical conductivity, so it is designed to be stacked on the maintenance The surface of theelectrode 16 is used as anauxiliary sustain electrode 16 for conducting electricity and inducing discharge. Theaddress electrodes 20 disposed on therear substrate 14 are made of metal such as silver or aluminum for writing data.

现有的等离子显示器的寻址电极设置在后基板的表面，由于与位于前基板上的维持电极距离较大，必需给予较高的电压才能发挥写入数据的作用。然而较高的电压不仅消耗大量电力，而且使等离子显示器产生过热。此外，现有的等离子显示器的寻址电极为一细长条形状，与维持电极重叠的面积过小，数据写入效果不佳。因此如何降低等离子显示器寻址电极所需的写入电压，并提高寻址电极数据写入的精确度，是现今等离子显示器研发上的重要课题之一。The addressing electrodes of the existing plasma display are arranged on the surface of the rear substrate. Since the distance between the addressing electrodes and the sustaining electrodes on the front substrate is relatively large, a higher voltage must be applied to play the role of writing data. However, the higher voltage not only consumes a lot of power, but also overheats the plasma display. In addition, the addressing electrode of the existing plasma display is in the shape of a thin strip, and the overlapping area with the sustaining electrode is too small, so the effect of data writing is not good. Therefore, how to reduce the writing voltage required by the addressing electrodes of the plasma display and improve the data writing accuracy of the addressing electrodes is one of the important issues in the research and development of the plasma display.

发明内容Contents of the invention

由于本发明的等离子显示器的寻址电极设置在前基板上，因此能有效降低寻址电极写入数据时所需的电压，且本发明的寻址电极设置于与阻隔壁重叠的位置，因此不影响等离子显示器放电单元的透光率。此外本发明的寻址电极包括一突出部分，设置于与第二维持电极平行并重叠的位置，可增加寻址电极与第二维持电极的重叠面积，因此可以提高数据写入的精确度。Since the addressing electrodes of the plasma display of the present invention are arranged on the front substrate, the voltage required for writing data by the addressing electrodes can be effectively reduced, and the addressing electrodes of the present invention are arranged at a position overlapping with the barrier wall, so there is no need to Affects the light transmittance of the discharge cell of the plasma display. In addition, the address electrode of the present invention includes a protruding portion, which is arranged parallel to and overlapped with the second sustain electrode, so that the overlapping area of the address electrode and the second sustain electrode can be increased, thereby improving the accuracy of data writing.

The surface of thefront substrate 52 further includes a plurality of first sustain electrodes 56 (not shown in FIG. 3 ) and a plurality of secondsustain electrodes 58 parallel to thefirst sustain electrodes 56 for discharge purposes; adielectric layer 60 is arranged on the first sustain electrodes 56 A sustain electrode 56 (not shown in FIG. 3 ) and a secondsustain electrode 58; a plurality ofaddress electrodes 62 perpendicular to the first sustain electrode 56 (not shown in FIG. 3 ) and the secondsustain electrode 58 are arranged on thedielectric layer 60 for writing data; and aprotection layer 64 disposed on theaddress electrodes 62 to protect the above electrodes.

维持电极一般是由氧化铟锡(ITO)或氧化锡(SnO₂)材料构成的透明电极(transparent electrode)，可以透过大部分可见光，然而它们却具有较大的电阻值，因此本发明的等离子显示器50另包括多个第一辅助电极70(图3未显示)与第二辅助电极72(图3未显示)，分别与第一维持电极56(图3未显示)和第二维持电极58电连接，用以增加第一维持电极56(图3示显示)和第二维持电极58的导电性能。其中，第一辅助电极70(图3未显示)与第二辅助电极72(图3未显示)的材料一般由铬/铜/铬(Cr/Cu/Cr)三层金属材料组成，可视情况将它们设置在第一维持电极56(图3未显示)和第二维持电极58的适当位置上。The sustain electrode is generally a transparent electrode made of indium tin oxide (ITO) or tin oxide (SnO₂ ), which can transmit most of the visible light, but they have a relatively large resistance value, so the plasma of the present invention Thedisplay 50 further includes a plurality of first auxiliary electrodes 70 (not shown in FIG. 3 ) and second auxiliary electrodes 72 (not shown in FIG. 3 ), electrically connected to the first sustain electrodes 56 (not shown in FIG. 3 ) and the secondsustain electrodes 58, respectively. connected to increase the conductivity of the first sustain electrode 56 (shown in FIG. 3 ) and the secondsustain electrode 58 .

请参考图5，图5为本发明等离子显示器50的上视图。由图5可知，本发明等离子显示器50的寻址电极62包括一突出部分74，以有效增加寻址电极62的面积，从而提高寻址电极62的效率。另外由于突出部分74设置在与第二维持电极58重叠的位置，且突出部分74的材料为ITO、IZO或其它可透光的复合导电材料，因此不影响等离子显示器50的透光率。此外，值得注意的是，由于本发明等离子显示器50的寻址电极62设置在与后基板的各阻隔壁相重叠的位置，再藉助于突出部分74与各维持电极相互作用，以使各放电单元的荧光层分别发出作为显示之用的红色、绿色与蓝色光，所以本发明的寻址电极62亦可完全由其他非透光的导电材料构成，或仅突出部分74为可透光的导电材料构成，以提高寻址电极62的导电性。Please refer to FIG. 5 , which is a top view of aplasma display 50 of the present invention. As can be seen from FIG. 5 , the addressingelectrode 62 of theplasma display 50 of the present invention includes a protrudingportion 74 to effectively increase the area of the addressingelectrode 62 , thereby improving the efficiency of the addressingelectrode 62 . In addition, since the protrudingportion 74 is disposed at a position overlapping with the second sustainelectrode 58 , and the material of the protrudingportion 74 is ITO, IZO or other transmissive composite conductive materials, it does not affect the light transmittance of theplasma display 50 . In addition, it is worth noting that since theaddress electrodes 62 of theplasma display 50 of the present invention are arranged at positions overlapping with the barrier walls of the rear substrate, and interact with the sustain electrodes by means of theprotrusions 74, the discharge cells The fluorescent layer of the fluorescent layer respectively emits red, green and blue light for display purposes, so theaddress electrode 62 of the present invention can also be completely made of other non-light-transmitting conductive materials, or only the protrudingpart 74 is a light-transmitting conductive material constituted to increase the conductivity of theaddress electrodes 62.

请参考图6。图6为本发明另一实施方式的等离子显示器50的上视图。由图6可知，本发明等离子显示器50的寻址电极62设置于二相邻阻隔壁66之间，且寻址电极62包括一突出部分74，上述突出部分设置于与第二维持电极58重叠的位置，以有效增加寻址电极62的面积，从而提高了寻址电极62的效率。值得注意的是在本实施方式中，寻址电极62设置于前基板52的放电空间内，为避免影响等离子显示器的透光率，可使用可透光的导电材料。Please refer to Figure 6. FIG. 6 is a top view of aplasma display 50 according to another embodiment of the present invention. It can be seen from FIG. 6 that the addressingelectrode 62 of theplasma display 50 of the present invention is arranged between twoadjacent barrier walls 66, and the addressingelectrode 62 includes a protrudingportion 74, and the above-mentioned protruding portion is arranged on the overlapping portion of the second sustainingelectrode 58. position, so as to effectively increase the area of theaddress electrodes 62, thereby improving the efficiency of theaddress electrodes 62.

与现有的等离子显示器相比，由于现有的等离子显示器的寻址电极设置在后基板上，因此需要给寻址电极施加较高电压，才能发挥写入数据的功能，反之，本发明将等离子显示器的寻址电极直接设置于前基板上，因此可以大幅度地降低寻址电极所需的电压及其反应时间。此外，现有的等离子显示器的寻址电极与维持电极重叠的面积不够大，因此写入数据时间过长，或者写入数据时产生误差，造成等离子显示器的色彩亮度效果不佳。但是在本发明的等离子显示器中，寻址电极还包括一突出部分，并设置于第二维持电极的下方，以藉助于增加寻址电极面积来提高寻址电极的效率及寻址能力。此外，本发明的等离子显示器的寻址电极设置于与后基板的阻隔壁相重叠的位置，而且突出部分的材料亦为透光的导电材料，因此不阻隔放电单元的透光率，不影响等离子显示器的亮度。Compared with the existing plasma display, because the addressing electrodes of the existing plasma display are arranged on the rear substrate, it is necessary to apply a higher voltage to the addressing electrodes in order to play the function of writing data. On the contrary, the present invention uses plasma The addressing electrodes of the display are directly arranged on the front substrate, so the voltage required by the addressing electrodes and its response time can be greatly reduced. In addition, the overlapping area of the addressing electrode and the sustaining electrode of the existing plasma display is not large enough, so it takes too long to write data, or an error occurs when writing data, resulting in poor color brightness of the plasma display. However, in the plasma display of the present invention, the addressing electrode further includes a protruding portion, which is disposed under the second sustaining electrode, so as to improve the efficiency and addressing capability of the addressing electrode by increasing the area of the addressing electrode. In addition, the addressing electrode of the plasma display of the present invention is arranged at a position overlapping with the barrier wall of the rear substrate, and the material of the protruding part is also a light-transmitting conductive material, so it does not block the light transmittance of the discharge cell and does not affect the plasma. The brightness of the display.

以上仅结合本发明的优选实施方式对本发明进行了描述，凡按本发明申请文件所述内容作出的等同改变与修饰，皆涵盖在本发明所要求保护的范围之内。The above only describes the present invention in combination with the preferred embodiments of the present invention, and all equivalent changes and modifications made according to the contents of the application documents of the present invention are covered within the scope of protection claimed by the present invention.
