The display of Erzhi's emissive film includes-a guide in the form of an edge-emitting broken glass plate (also known as a light guide plate), an active plate or a back plate. It also includes a light front plate, also known as a passive plate. -Light-scattering chirps (also known as flexible elements) are held between spacer elements placed on these boards. Distributing the spacer elements across the plates defines the size and location of individual images (pixels) displayed by the box film. -The film electrode layer is placed at least on the light scattering: film to> side so as to enable-the voltage on the A body-the voltage can be applied to the box film to thereby use the box film electrode as a common display electrode . There are respective parallel electrode groups on the two boards, and the parallel electrodes are arranged perpendicularly to / k so as to form a group of column electrodes on the & board and a group of row electrodes on the light guide plate. By applying a suitable electric mill to the falling film electrode and the appropriate electrode located on the light guide plate and the front plate, two opposing static electricity can be generated on the box film: and these force components are respectively directed toward the light guide plate and the front plate . The balance of these two relative electrostatic forces combined with the elastic force existing in the foil film is used to attract a part of the foil film associated with a single pixel facing the light guide plate or front plate: usually, by Apply between the partial row electrodes on the optical device: a greater voltage difference between the #filtrated film electrode and the local column electrode on the front panel to locally attract the foil film toward the light guide plate. Similarly, by applying a voltage difference between the electrode and a local column electrode on the plate such as a larger voltage difference between the foil film electrode and the local row electrode on the light guide plate, the foil is attracted to 99076.doc 200539074.

The partially scattered light of the rule board can reach: show the viewer, the eyes, and thus generate in the display-the partially bright image light is partially supplied to the light guide device, and the rest is guided to read The viewer is displayed and therefore becomes invisible. On the other hand, when a part of the box film related to the early pixel is in partial contact with the front plate, no light is partially retreated from the light guide device, and the other part of the magic medium appears as a partially dark pixel. A dynamic falling film display of this general emissive type is known from WO / 38163. [Summary of the Invention] However, there are cases when it is advantageous to make a dynamic falling film exhibit reflective properties instead of emissive properties. This provides a reflective dynamic film display that includes a plurality of local pixels capable of reflecting or absorbing ambient light incident on the respective local pixels of the display. The reflective foil display does not depend on the presence of a light guide plate or on a light source that couples light into the light guide device. The truth is that 'only-a thin backplane and the presence of ambient light are sufficient. Because & reflective = display can be made thinner, lighter and consume significantly less electrical power than emissive foil display. The latter features enhance the portability of the display, allow more design freedom when creating a flexible display, and enhance the applicability of the display in various environments. One object of the present invention is to meet the demand for reflective foil film display. This is 99076.doc 200539074 by revealing a ^^

According to the present invention You ’re right here, the flexible element includes a light-reflecting layer. Part of the result: Although a part of the flexible element related to the early-pixels is in partial contact with the sun, it passes through the front plate. The emission layer was concealed by Yue Lin she #b% especially because of this first transgressor: Γ The inspector reflected back, and this part of the observation, and it's produced by this-bright pixels. Partially incident and reflected light Way; ^ φ I + /, I sub-light in the light absorbing material and / or color filter, then the lighting two-day knife "white. If there is a color filter in the path of incident light: ", and the bright part is colored. The color filter can be placed on the side of the frontal element of the front plate 'or on the side of the reversible element. One side of the front plate. An absorptive non-scattering color filter is used, which includes a two-dimensional geometric pattern with red, green, and blue spots. The size of the spots corresponds to the pixels displayed by the reflective foil film. By disposing a light scattering member between the light reflecting layer included in the flexible element and the-side of the flexible element facing the front plate, the reflected light from the light reflecting layer is in a wide angle range. Becomes scattered, thereby generating a wide viewing angle. 0 is ignored by diffusing the light scattering member into the flexible element, and by substantially avoiding the presence of light scattering members in the path of incident and reflected light, and by using a A flexible element including a specular reflection type light reflection layer, and the locally reflected light from the flexible element becomes specular reflection. Then, the foil film of the present invention can display incident pixels from all locally existing pixels by allowing incident light to be separately present. Or since Some display pixels are specularly reflected, and partially or completely become 99076.doc 200539074 into a specular surface. In addition, the flexible element should be wrapped around a substantially electrically insulating light absorbing fluid. This allows application across the fluid. The electric field produces a good optical alignment. When a part of the flexible element associated with the pixel is in contact with the backplane, the pixel appears dark because substantially no incident light is reflected back from the part toward the observer. The truth is that the person's light is absorbed by the black fluid that exists between the front plate and the flexible element.

This is-a way to provide-a single and effective way to black light absorbing fluid. As an alternative, this solution can be combined or exchanged with a solution in which the light absorbing fluid includes substantially non-scattering black pigment particles. This also has the advantages described above that can simply and effectively provide a black light absorbing fluid. If the light absorbing fluid includes black pigment particles, these particles should preferably have a diameter of -close to 5-50 nm, which gives a generally non-scattering fluid good light absorption characteristics. Preferred black pigment particles include carbon black particles. The flexible element is preferably a fluid permeable element, so that when parts of it move separately, they come into contact with the front plate and the back plate and move without contact with the front plate and the back plate. At this time, fluid can pass through the flexible element. This gives the advantage that the fluid can be quickly moved from one side to the other of the flexible element, and therefore parts of the flexible element can be quickly switched into contact with the front plate and not with the front plate. contact. By providing fine holes in the flexible element, the penetrable characteristics of the releasable pieces can be better obtained. This is a way to provide the fluid penetrability 99076.doc 200539074 component ordering and effective. 5 Haisi pores should have a diameter of at least 0.5 μπί and these pores should exist at a bulk density of at least 0.5% of the volume of 4 flexible elements, so that the above particles are not blocked. The pores allow the & body to flow smoothly through the flexible element. The pores should be straight pores, which further enhances the above advantages of an effective and fast fluid flow through the flexible element, so that fast switching of individual pixels can be completed. In addition, the light reflecting layer should be disposed on one side of the flexible element facing away from the front plate. This provides the back reflection and scattering of the reflected light toward the viewer of the display by the light scattering member provided to the flexible element. . The light reflecting layer should preferably include an aluminum coating, which is a cheap way to provide good reflectivity. By ignoring the light-scattering member being incorporated into the flexible element, the presence of a specularly reflective aluminum coating disposed on the flexible element allows the inventive foil film display to be used as a mirror display. . The light reflecting layer on the flexible TG component should also include a flexible element electrode. With the flexible element electrode, a potential can be applied to the flexibility with reference to the embodiments described below. It will become obvious. [Embodiment] These and other aspects of the present invention will be illustrated in FIG. 1-a universal type of reflective dynamic box film display (DFD). The display device includes a front plate 2, a flexible element or a light scattering system, and back plate electrode systems 5, 6 respectively disposed on the surfaces of the front plate 2 and the back plate 4 and the element 3. The door 99076.doc 200539074 compares Fig. 2. The electrodes 5 and 6 form two groups of vertically oriented electrodes. The two groups of electrodes are preferably 90. The corners cross each other. A pixel exists at each intersection of the electrodes 5 and is defined by adjacent spacer elements 11 arranged on each of the plates 2 and 4. By generating a potential difference locally between the electrode 5 and the flexible element 3 on the one hand and between the electrode 6 and the flexible element 3 on the other hand, and by adding electricity to the electrodes 5, 6, and The balance of the anti-static electrostatic force of the flexible element 3, the anti-attractive electrostatic force is locally applied to the interchangeable element 4, such as the other plate 2 and the back plate 4, will cause the flexible element 3 to be pulled toward the front plate 2 or向 背板 4。 Back plate 4. ^ As shown in FIG. 2, the electrodes 5 and 6 form a passive matrix structure. A selection signal (voltage) is supplied to the electrodes from a cymbal unit 12 including a selection member. This set of selection signals determines the set of potentials on electrodes 5 and 6. In addition, a separate electric dust is applied to the flexible element 3. By applying a suitable potential to the electrodes 5, 6 and the flexible element 3, the flexible element 3 can be actuated in operation at the position of the selected X cross point of the electrode 5 "6 to move towards the electrode 5 respectively And 6 or move away from electrodes 5 and 6, and vice versa. Electrode $ forms a row electrode 'meaning the electrode extends in a "short," direction of a rectangular display, while electrode 6 forms a column electrode or a wire electrode, meaning the electrode This display extends in the "long" direction. Referring now to FIGS. 3a and 3b, a knife of a display device according to the present invention is shown as a sub-meter * a single pixel, and the flexible element 3 has a light reflecting coating 7 on its side facing away from the moon plate 2. (It should be an inscription.) The light reflecting coating 7 also serves as a flexible element electrode. In addition, referring to Figures 3a and 3b, the flexible element 3 is surrounded by a black, light-absorbing 99076.doc 200539074 power-receiving insulating fluid 8. The fluid 8 can be obtained by: constituting the fluid 8 with electric black, bar, and dysprosium black dyes, dissolving at least one black dye in the body 8 and / or non-scattering, for example, 5-50 nm Black particles 2 (for example, carbon black particles having high ejection properties) are dispersed in the fluid 8. The w-body 8 must have electrical insulation on its body to allow electricity to be applied across the fluid, and the flexible element 3 can be moved towards the plates 2 and / or 4 respectively, or away from the plate, by these electric fields. 2 and / or 4. -The black fluid 8 can penetrate the flexible element 3. Comparing Fig. 4, the flexible member 3 has fine holes 9 according to the embodiment shown. When the releasable element 3 is switched between the states shown in Figs. 3a and 3b, the pores 9 allow fluid 8 to flow through the releasable element 3, and when the flexible element 3 is applied to the electrodes 5 and 6 Under the influence of the voltage on the flexible element electrode (reflection layer) 7, the fluid 8 quickly moves sideways from one of the flexible elements 3 when it moves from the front plate 2 to the back plate 4. To the other side, and vice versa. The pores 9 in the flexible element 3 should have a diameter of at least 0.05 μm so that the carbon black particles described above or any aggregates of these particles will not block the pores 9. The pores 9 should be straight pores, and their presence should constitute a volume density of at least 0.5% of the total of the flexible element 3, so that the fluid 8 can be smoothly from one side of the flexible element 3 Flowing through these pores to the other side of the flexible element 3: In this case, straight means that the pores 9 can extend through the flexible element substantially perpendicular to the surface of the foil, as shown in Figure 4 As shown, it is a sectional perspective view of the pores 9 in the flexible element 3. As shown in FIG. 3a, the displayed portion of the flexible element 3 is related to a single pixel displayed by the moving β film of the present invention and it is in contact with the back plate 4 99076.doc 200539074 in the first state. Here, the maximum amount of g $, you ..., the color body 8 exists between the flexible element 3 and the front plate 2. It is incident on the front plate 2 and # H a. The upper front line 10 penetrates the front plate 2 and is absorbed by the light absorbing fluid 8. Therefore, when observing a part of the flexible element 3 described by the display of the front panel 2 there is substantially no light that can reach the viewer's eyes from the dynamic foil film. The pixel is black because it is shown to be transmissive and because

In this case, 'a minimal amount (if any) of the black fluid 8 exists between the flexible, sheet L' plates 2. The light that a person shoots on the front plate 2 is called yellow through the front plate 2 and is scattered or reflected back by the reflective coating 7 on the flexible TG member 3-the observer who observes the front plate 2. Therefore, the pixels of the dynamic diaphragm display associated with a part of the flexible element 3 shown in Fig. 3b appear bright to the observer. Therefore, the membrane display device includes a back panel ⑷, a front panel ⑺, and flexibility 4 (3). The column and row electrode members (5, 6) are configured so that one or more parts of the flexibility element (3) are in contact with the front plate (!) Or are not connected to the front plate (2) = significant ^ flexibility The element (3) includes a light reflecting layer ⑺. Therefore, the incident light is self-defeating, and the portion where the flexible element is in contact with the front plate is reflected.
