Description of the invention: [Technical field to which the invention belongs] The present invention relates to a display device having a light guide plate optically coupled to a light source, a passive panel facing the light guide plate, and a light guide plate disposed on the light guide plate. An electrostatic operable element and two sets of electrodes between the passive panel and the passive panel. The electrodes are configured to cause electrostatic forces on the element and bring selected portions of the element into contact with the light guide plate, thereby extracting light from the light guide plate. [Prior Art] A conventional foil display is described in, for example, WO 00/38 163. Shown in the figure: The display includes a light guide plate 10 and a non-light plate 12 with a political beam 14 interposed therebetween. There are individual groups of parallel electrodes 16, 18 arranged perpendicular to each other on the two boards. The electrodes on the light guide plate are arranged in the row direction, and the electrodes on the non-light plate are arranged in the column direction. The box is also provided with an electrode layer 20. These electrodes are formed by an IT0 layer formed on each of the mentioned surfaces. The intersection of each set of these electrodes defines the pixels of the display. By applying a voltage to the appropriate electrodes on the light guide plate, non-light plate, and foil, the box can be sucked until the light guide is reversed. When the box is brought into contact with the light guide plate, light is extracted from the light guide plate. In order to minimize the absorption rate, the light guide plate is made relatively thick, so that the number of reflections caused by the surface of the light guide plate is reduced. This means that the amount of light that can be extracted from the light guide plate per unit length is relatively small 'and it is proportional to the number of reflections per light ray. Therefore, in order to achieve sufficient brightness, Ricoh's bistable uses a sub-field addressing scheme. However, the control of the bi-stable switching in the "Knowledge" display is more difficult. 99079.doc 200537202 Difficult "Because the switching curve varies from place to place. This is shown in Figure 2, where = indicates the ⑽ switching curve, 24 indicates the pitch switching curve, and% indicates that the stretching of the L 疋 region switching curve reduces the overall bi-stable region, which can cause some pixels to remain ⑽ and some pixels It remains at 0ff, which causes a display failure. [Summary of the Invention]: The purpose of the month is to provide a foil display, which can be more reliably addressed. This and other objectives are achieved by a device of the type mentioned in the introduction, in which the two sets of electrodes are provided on the light guide plate and the passive panel, and they are configured to define a plurality of pixel regions, 'of which are different The unique combination of electrodes of the electrode group has an extension in each pixel region. Therefore, these two electrode groups can be arranged on a passive (non-light) panel or a light guide (active panel). All electrodes have an electrical house, and then the electrical waste is reduced or removed for the -electrodes in each group. By having one electrode in each group: less the voltage, the pixel area where these two electrodes extend will be greater than any; the pixel area will have this lower voltage over a larger area, and will therefore The force of reducing or eliminating the emission in this particular pixel area. Or a lightning potential applied to each group. This guide ^ # Setting the electrode lower or zero results in an increase in the force exerted on the 特定 in a specific pixel area. The present invention is based on the understanding that by arranging two electrode groups on the same panel, the force that can only be changed by changing the working force ^ "the force acting on the movable panel-the panel, and the force toward the other panel- Keep it strange to address the display. For example, 99079.doc 200537202 2 In the case where two electrode groups are arranged on a passive panel, the force towards the passive panel can be changed, and the force applied to ° ^ π 70 pieces towards the light guide plate can be maintained Constant: Therefore, 'by reducing the force towards the passive panel, the image can be:' By: bringing the part of the electrostatically operable element into contact with the light guide plate: The strange force towards the light plate can be achieved by, for example, a common configuration The electrode is achieved by light guide =. Arranging the two sets of structured electrodes on a single panel according to the present invention enables more robust addressing. One group of electrodes should be arranged mainly in the column direction, and the other electrodes should be arranged in the row direction. Potential and Wang Yao = As mentioned, the pixels of the display are defined by two electrodes that belong to different groups. Therefore, a certain pixel is a unique region in which an electrode from one of the mother-electrode group exists. Each electrode should preferably cover approximately half of a particular pixel area. As a result, if equal voltage is applied to both electrodes, the contribution of each electrode is equal. One advantage of this is that when one of two equal voltages (such as column voltage) applied to the electrodes is removed, the force reduction is-· 4 times. In the conventional addressing, the column and row electrodes are arranged on different sides of the electric field that generates the force, and have a given potential, either positive or negative. If the electrode is grounded, the difference in electricity is reduced by π. The reduced voltage drop can be used to achieve a more stable addressing, which is less sensitive to the precise overlap of the bistable region ', thereby reducing the number of pixel failures significantly. Therefore, it is possible to achieve very stable addressing of the sub-field addressing scheme. If, for example, a row is selected by removing the row of electricity, and a number of pixels in the selected row are turned into a row by removing the row of electric motors, then here—the other row in the selected row Pixels and (in the unselected) these lines will not be affected as much as in the conventional display 99079.doc 200537202 display. One ί two! The two groups of electrodes in the prime & domain can be arranged in a common layer or in two different layers, i.e. the column electrodes are in one layer and the row electrodes are in the other layer. According to the embodiment of the present invention _ ^ ^ ^ y. In the embodiment of the chain, two sets of structured electrodes are arranged on the passive panel. In this embodiment, the force exerted on the movable member toward the light guide plate can be kept strange, and thus passive

Therefore, these light guide plates can be kept "cleaner", which is advantageous in terms of brightness and contrast. The light guide plate should be provided with an electrode layer to provide an electrostatic force. Therefore, a constant voltage level can be applied The electrode can be used to achieve a function of the fixed box to fight the moon's power. The force will absorb the element to the light guide plate. The electrode layer: unstructured or structured. Because the light guide plate can be called through The sheet causes a short circuit between the electrode on the movable element and the electrode layer on the light guide plate. One of the advantages of the structured electrode layer is increased reliability. The light guide plate electrode layer (for example) can be structured as a column or The product can be independently addressed. The ghost can reset the block or column, that is, the QFF switch of the entire block or column can be achieved. This can then achieve a more efficient addressing scheme. The above-mentioned light guide plate electrodes can be arranged on the face of the light guide plate. The side of the movable element or the opposite side of the light guide plate relative to the movable element, that is, the side of the light guide plate. One of the advantages of the latter is that the brightness and contrast characteristics can be further improved. 99079.doc 200537202 In the second embodiment, the electrode layout of the light guide plate and the passive panel is reversed. That is, two sets of structured electrodes are arranged on the light guide plate of the display. However, this requires a closed addressing scheme and a component for adjusting the light source. In this second embodiment The passive panel is advantageously provided with an electrode layer for providing a common electrode. It is preferred that the movable element is provided with a structured electrode layer. The electrode layer

The spacers 38 and 39 are arranged on each side of the drop 36 so that the autonomous panel 32 and the passive panel 34 are separated. The display device further includes a column electrode 40 and a row electrode 42. In Fig. 3 & Sun, a row of electrodes 40 and a row of electrodes 42 are shown. These electrodes may be formed from the IT0 layer. According to the first embodiment of the present invention, both the column and row electrodes 40 and 42 are disposed on the passive panel 34, as shown in Figs. 3a and 3b. In FIG. 3a, the column and row electrodes 40 and 42 are arranged in the upper layer of the passive panel. In this case, since the column and the row electrodes cross each other, different metal layers are used, which uses the panel's electrode. The pathway in 2 is connected to Ting 0. In Figure 3b, the column and row electrodes 40, 42 are arranged in different layers, that is, the column electrodes are in one layer and the row electrodes are in another layer. These technologies are from (for example) AMLCD panels Known. The layout of column and row electrodes is described in further detail in Figures 4a-4d. Figure 乜 shows a column of electrode group 31 and a row of electrode group 33 ^ Column electrode 40 belonging to electrode group 31 and row electrode 42 belonging to electrode group 33 This unique combination has eight extensions in the pixel area 41. The pixel area 41 is limited by the spacer 39, which therefore helps define the pixel area. Figures 4b-4d also show a top view of a pixel 41 by further exemplifying the electrode layout. In the figure In 4a-4d, both the column electrode 40 and the row electrode 42 have a substantially comb-shaped structure. The comb-shaped column electrode 40 and the comb-shaped row electrode 42 are arranged to be staggered with each other so that each electrode covers approximately the pixel area. Half of However, its electrode layout can also be used. For example, the pixel area can be simply divided into two, the middle column electrode extends in one half of the pixel area, and the row electrode extends in the other half 99079.doc 10 200537202. Returning to FIGS. 3a-3b, the display device 30 further includes a common electrode 44 disposed on the active panel 32. According to the operation of the display, light from a light source (such as a Led 46) is coupled into the active panel 32. The light is confined to the active panel by total internal reflection. By applying an appropriate voltage to the electrodes 37, 40, 42, and 44, the foil 36 is brought into contact with the active panel to extract light from the active panel 32, such as _ It is further described below. 示意 5 shows the switching curve and switching points corresponding to the electrode configuration in Figure "and 3b". The voltage difference between the common electrode 44 and the foil electrode 37 of the active panel is not vaetive, and the voltage between the foil electrode 37 and the pixel region 41 (that is, the combination of the column electrode 40 and the row electrode 42 on the passive panel 34). The difference is labeled Vpassjve. The detailed operation of the sub-field addressing scheme is described below. First, all pixels are switched to 0FF by a solid OFF measure. For example, • set v — = 0v by grounding the common electrode 44 and apply the same voltage (Vrew, VeQi) to the column and row electrodes (such as 50 V) to increase Vpassive. This corresponds to the position 50 in FIG. 5, which is located in the FF region 52. It is assumed here that the box is grounded (VfQil = 〇). Then increase the voltage difference U to a constant potential (eg 40 V). This pair of boxes generates a force toward the active panel 32, while moving the pixels to position 56 in the bistable region 58. So the pixel stays in its ## state, so it is clear. Then, during the -column pulse, the column electrode 4g to be addressed is set to zero potential (vrow ', which reduces the voltage difference ν_ν6. When the column electrode is grounded-99079.doc 11 200537202 the images in this column Yin Xi KK ^] Γ2 = [^ 2 = ν 烕 烕 ^ ^^ Λ potential. (As described above, 'Assume that each column and row electrode each cover half of the pixel area.) For ancient times, Wu.

This reduction, VL ^ b, code 乂 / σ This column applies the force applied to the foil toward the passive panel, and moves it to the still-open King 1 is at position 60 in the bistable chirped area. Then 'but still in the column pulse, the row electrode 42 of the pixel that should emit light is also set to zero potential during a chirped pulse, thereby selecting the column in the selected column. The pixel potential in the pixel will be zero (both the column and row electrodes are set to zero). This means that the electrical difference is ~~ also zero 'and the pixel is moved to the bit position in the ON area 64. ll, white position 0 .This is caused by the fixed force towards the active panel, & etc.? | Will be sucked to the active panel, thereby the pixel is switched to ⑽, ie The active panel emits light at these selected pixels. After the row and column pulses, all pixels return to position 56 'in the bistable region 58 and the pixels that have been switched to ⑽ will remain ⑽. Then a new column pulse comes Select-New Column 'and repeat the procedure until the entire display is addressed. It should be noted that the voltage difference between the foil and any electrode is preferably changed in each frame to minimize charging. As mentioned above, the voltage difference The vaetive is constant throughout the addressing process, whereby positions 56, 60, and 62 are on the horizontal line in Figure 5. After a period of light generation, the light source is turned on during this time, and a solid OFF measure can be applied again to place all pixels in As seen in Figure 5, the fact that the voltage difference will first reduce the heart rate is due to the electrode configuration of the present invention, which positions the central switching point 60 closer to the switching point than the switching 99079.doc -12- 200537202 point 62 56. The proximity of the two switching points in the bistable area makes switching more stable. The embodiment of the display device according to the present invention described above with reference to FIGS. 3-5 may be used for addressing row by row. In his case; Among other things, the switching voltage and the bi-stable region make the switching point outside the bi-stable region. The present invention is not limited to the above embodiments. Those skilled in the art will recognize that the present invention can be implemented without departing from Fan Tianshou made changes and modifications. • For example, 'resistance reduction metallization can be added to each electrode layer, which reduces the resistance of ITO. This means that the display can be addressed faster. [Schematic description] Figure 1 is A schematic cross-section of a display according to the prior art.
