Description

Technical Field

[0001] This invention relates to a display, and more particularly to a display with a radial gradient grayscale display effect. Background Technology

[0002] A bistable display is a type of display that uses a bistable medium for display. Technologies that achieve bistable display include electronic ink (E-Ink) display, cholesterol liquid crystal display (ChLCD), electrophoretic display (EPD), electrowetting display (EWD), and quick response-liquid powder display (QR-LPD).

[0003] Because bistable displays have lower operating power consumption and better flexibility compared to mainstream displays (such as LCDs or LEDs), they are suitable for use not only in portable electronic products (such as e-paper or e-books) but also in the casings of various electronic products or vehicle bodies to achieve visual effects. However, due to limitations in current driving methods, bistable displays cannot produce radial gradient grayscale display effects. Summary of the Invention

[0068] In the accompanying drawings, the thicknesses of layers, films, panels, regions, etc., are enlarged for clarity. It should be understood that when a component such as a layer, film, region, or substrate is referred to as being "on" or "connected" to another component, it may be directly on or connected to the other component, or an intermediate component may also be present. Conversely, when a component is referred to as being "directly on" or "directly connected" to another component, no intermediate component is present. As used herein, "connection" can refer to a physical and / or electrical connection. Furthermore, an "electrical connection" may mean the presence of other components between the two components.

[0069] Reference will now be made in detail to exemplary embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same element references are used in the drawings and description to denote the same or similar parts.

[0070] Figure 1 This is a top view of the display according to the first embodiment of the present invention. Figure 2 yes Figure 1 A cross-sectional view of the display. Figure 3 yes Figure 2 The equivalent circuit diagram of the display. Figure 2 Corresponding to Figure 1 At section line A-A'. Please refer to... Figure 1 and Figure 2 The display 10 includes a first substrate 101, a second substrate 102, a first electrode 110, a second electrode 120, and a display medium layer 200. The first substrate 101 and the second substrate 102 are disposed facing each other. The first electrode 110 covers the entire surface of the first substrate 101. The second electrode 120 covers the entire surface of the second substrate 102. The display medium layer 200 is disposed between the first substrate 101 and the second substrate 102. In this embodiment, the first electrode 110 and the second electrode 120 are respectively disposed on surfaces 101s1 and 102s1 facing each other on the first substrate 101 and the second substrate 102, but this is not a limitation.

[0071] The materials of the first substrate 101 and the second substrate 102 may include glass, quartz, polymers (e.g., polyimide, polycarbonate, or polyethylene terephthalate), or other flexible sheets with high light transmittance. The first electrode 110 and the second electrode 120 may be, for example, light-transmitting electrodes, and the materials of light-transmitting electrodes include metal oxides, such as indium tin oxide, indium zinc oxide, aluminum tin oxide, aluminum zinc oxide, or other suitable oxides, or a stack of at least two of the above, but are not limited thereto. In some embodiments, the materials of the first electrode 110 and / or the second electrode 120 may also be metallic materials (e.g., molybdenum, aluminum, copper, etc.).

[0072] The display medium layer 200 may include a plurality of microcapsules 210 and electronic ink 220 filled within the microcapsules 210. The electronic ink 220 optionally includes a plurality of white particles 221, a plurality of black particles 222, and a transparent liquid 223, wherein one of the white particles 221 and the black particles 222 may be positively charged and the other negatively charged. That is, in this embodiment, the material of the display medium layer 200 may be an electrophoretic display (EPD) material.

[0073] However, the present invention is not limited thereto. According to other embodiments, the display medium layer may also be a liquid powder display (LPD) material, a cholesterol liquid-crystal (CLC) material, a microelectromechanical system (MEMS) material, an electrochromic display (ECD) material, a polymer-dispersed liquid crystal (PDLC) material, or other suitable bistable media.

[0074] Furthermore, the first electrode 110 and the second electrode 120 may be provided with multiple voltage input terminals. For example, the opposite side edges 110e1 and 110e2 of the first electrode 110 may be provided with voltage input terminals 110in1, 110in2, 110in3 and 110in4, while the opposite side edges 120e1 and 120e2 of the second electrode 120 may be provided with voltage input terminals 120in1, 120in2, 120in3 and 120in4.

[0075] In this embodiment, the display 10 may further include a third electrode 130 disposed on the side of the first electrode 110 opposite to the second electrode 120. The third electrode 130 has an end portion 131 and an extension portion 133. The end portion 131 may be disposed on the first substrate 101 at a position away from the edge of the substrate, for example, at the geometric center of the first substrate 101 (e.g., the edge of the substrate). Figure 1 (as shown) or other locations that are off-center from the geometric center and far from the edge of the substrate.

[0076] On the other hand, the extension 133 may extend from the end portion 131 to the side edge 101e of the first substrate 101, and an insulating layer 115 is provided between the extension 133 of the third electrode 130 and the first electrode 110. In order to reduce the capacitive coupling effect between the extension 133 of the third electrode 130 and the first electrode 110, the material of the insulating layer 115 may be an insulating material with a high dielectric constant. For example, in this embodiment, the third electrode 130 and the insulating layer 115 are located between the first substrate 101 and the first electrode 110, the insulating layer 115 covers the third electrode 130, and the end portion 131 of the third electrode 130 penetrates the insulating layer 115 to electrically contact the first electrode 110, but this is not a limitation.

[0077] Since the end 131 of the third electrode 130 is in electrical contact with the first electrode 110 at the geometric center of the first substrate 101, the end 131 can serve as another voltage input terminal of the first electrode 110 at or near the geometric center of the first substrate 101. Please also refer to... Figure 3 For example, the voltage input terminal 110in1 (or voltage input terminal 110in3) located on the side edge 110e1 of the first electrode 110 can be used as a first voltage input terminal for inputting a first voltage V1. The voltage input terminal 110in2 (or voltage input terminal 110in4) located on the other side edge 110e2 of the first electrode 110 can be used as a second voltage input terminal for inputting a second voltage V2. The end 131 of the third electrode 130 located between the first voltage input terminal and the second voltage input terminal can be used as a third voltage input terminal for inputting a third voltage V3.

[0078] Similarly, the voltage input terminal 120in1 (or voltage input terminal 120in3) located on the side edge 120e1 of the second electrode 120 can be used as the fourth voltage input terminal for inputting the fourth voltage V4. The voltage input terminal 120in2 (or voltage input terminal 120in4) located on the other side edge 120e2 of the second electrode 120 can be used as the fifth voltage input terminal for inputting the fifth voltage V5.

[0079] In this embodiment, when the display 10 is enabled, the third voltage V3 input to the first electrode 110 can be greater than or less than the first voltage V1 and the second voltage V2, and the fourth voltage V4 input to the second electrode 120 is different from the fifth voltage V5. That is, the potential distribution on the first electrode 110 gradually increases or decreases from the third voltage input terminal (i.e., the end 131 of the third electrode 130) towards the first and second voltage input terminals on both sides, while the potential distribution on the second electrode 120 gradually increases or decreases from the fourth voltage input terminal on one side edge 120e1 towards the fifth voltage input terminal on the other side edge 120e2. Accordingly, the display medium layer 200 sandwiched between the first electrode 110 and the second electrode 120 can achieve a radially gradient grayscale display effect.

[0080] like Figure 1 As shown, the grayscale of the display 10 can exhibit a gradually increasing effect centered on the end 131 of the third electrode 130 (i.e., the third voltage input terminal of the first electrode 110) and extending outwards, i.e., a radial grayscale increasing effect. It should be noted that by adjusting the relative magnitude of the third voltage V3 to the first voltage V1 and the second voltage V2, the grayscale of the display 10 can also exhibit a radial display effect centered on the end 131 of the third electrode 130 (or the geometric center of the first substrate 101) and extending outwards.

[0081] In this embodiment, the display 10 further includes flexible circuit boards 311, 312, 313, and 314. For example, each of these flexible circuit boards may have two sets of connection pins, one set electrically connected to a voltage input terminal of the first electrode 110, and the other set electrically connected to a voltage input terminal of the second electrode 120. For instance, one set of connection pins of flexible circuit board 311 is electrically connected to voltage input terminal 110in1 on the first electrode 110, while the other set of connection pins is electrically connected to voltage input terminal 120in1 on the second electrode 120, and so on, but not limited thereto.

[0082] Other embodiments will be listed below to illustrate this disclosure in detail, wherein the same components will be marked with the same symbols, and the description of the same technical content will be omitted. For the omitted parts, please refer to the foregoing embodiments, and they will not be repeated below.

[0083] Figure 4 This is a cross-sectional schematic diagram of a display according to a second embodiment of the present invention. Please refer to... Figure 4 The display 10A in this embodiment and Figure 2 The only difference in the display 10A is the configuration of the third electrode and the insulating layer. Specifically, the third electrode 130A and the insulating layer 115A of the display 10A are disposed on the side of the first substrate 101 facing away from the first electrode 110, and the insulating layer 115A is located between the first substrate 101 and the extension 133 of the third electrode 130A. It is particularly noteworthy that, in this embodiment, the end 131 of the third electrode 130A is not in direct electrical contact with the first electrode 110, but is electrically coupled to the first electrode 110. That is, the end 131 of the third electrode 130A changes the charge distribution of the first electrode 110 near the end 131 through capacitive coupling effect, thereby changing the potential at that point.

[0084] Figure 5 This is a cross-sectional schematic diagram of a display according to a third embodiment of the present invention. Please refer to... Figure 5 The display 10B in this embodiment and Figure 4The only difference between display 10B and display 10A is the configuration of the first electrode. Specifically, the first electrode 110A, third electrode 130A, and insulating layer 115A of display 10B are disposed on the side of the first substrate 101 facing away from the display medium layer 200. Unlike... Figure 4 The third electrode 130A is electrically coupled to the first electrode 110. In this embodiment, the end 131 of the third electrode 130A is in direct electrical contact with the first electrode 110A, which is also located outside the first substrate 101.

[0085] Figure 6 This is a cross-sectional schematic diagram of the display according to the fourth embodiment of the present invention. Figure 7 yes Figure 6 The equivalent circuit diagram of the display is shown below. Please refer to... Figure 6 and Figure 7 The display 10C in this embodiment and Figure 2 The difference between the display 10 and the first electrode 110 is that the display 10C also includes a fourth electrode 140 and an insulating layer 125. The fourth electrode 140 is disposed on the side of the second electrode 120 opposite to the first electrode 110, and has an end portion 141 and an extension portion 143. Similar to the third electrode 130, the end portion 141 of the fourth electrode 140 can be disposed approximately on the second substrate 102 and away from the edge of the substrate, for example, at the geometric center of the second substrate 102 (e.g., the edge of the substrate). Figure 6 (as shown) or other locations that are off-center from the geometric center and far from the edge of the substrate.

[0086] On the other hand, the extension 143 may extend from the end portion 141 to the side edge 102e of the second substrate 102, and an insulating layer 125 is provided between the extension 143 of the fourth electrode 140 and the second electrode 120. To reduce the capacitive coupling effect between the extension 143 of the fourth electrode 140 and the second electrode 120, the insulating layer 125 may be made of an insulating material with a high dielectric constant. For example, in this embodiment, the fourth electrode 140 and the insulating layer 125 are located between the second substrate 102 and the second electrode 120, the insulating layer 125 covers the fourth electrode 140, and the end portion 141 of the fourth electrode 140 penetrates the insulating layer 125 to electrically contact the second electrode 120, but this is not a limitation.

[0087] Since the end 141 of the fourth electrode 140 is electrically in contact with the second electrode 120 at the geometric center of the second substrate 102, the end 141 can serve as another voltage input terminal of the second electrode 120 at or near the geometric center of the second substrate 102. For example, the end 141 of the fourth electrode 140 located between the fourth voltage input terminal and the fifth voltage input terminal can serve as a sixth voltage input terminal for inputting a sixth voltage V6 (e.g., ...). Figure 7 (As shown).

[0088] In this embodiment, when the display 10C is enabled, the third voltage V3 input to the first electrode 110 can be greater than or less than the first voltage V1 and the second voltage V2, and the sixth voltage V6 input to the second electrode 120 can be greater than or less than the fourth voltage V4 and the fifth voltage V5. That is, the potential distribution on the first electrode 110 gradually increases or decreases from the third voltage input terminal (i.e., the end 131 of the third electrode 130) towards the first and second voltage input terminals on both sides, while the potential distribution on the second electrode 120 gradually increases or decreases from the sixth voltage input terminal (i.e., the end 141 of the fourth electrode 140) towards the fourth and fifth voltage input terminals on both sides. Accordingly, the display medium layer 200 sandwiched between the first electrode 110 and the second electrode 120 can achieve a radially gradient grayscale display effect.

[0089] Figure 8 This is a top view of the display according to the fifth embodiment of the present invention. Figure 9 yes Figure 8 A cross-sectional view of the display. Figure 10 This is a cross-sectional schematic diagram of the display according to the sixth embodiment of the present invention. Figure 9 Corresponding to Figure 8 At section line B-B'.

[0090] Please refer to Figure 8 and Figure 9 The display 20 in this embodiment and Figure 1 and Figure 2 The difference between the display 10 and the display 20 is that the first substrate 101A, the first electrode 110B, and the display medium layer 200A of the display 20 have an opening OP. This opening OP is generally located at or near the geometric center of the first substrate 101A and exposes the voltage input terminal 110in5 (i.e., the third voltage input terminal) of the first electrode 110B and the voltage input terminal 120in5 (i.e., the sixth voltage input terminal) of the second electrode 120. It is particularly noteworthy that, in this embodiment, the display 20 does not have such an opening OP. Figure 6 The third electrode 130 and the fourth electrode 140 shown are used as the third voltage input terminal of the first electrode 110B and the sixth voltage input terminal of the second electrode 120.

[0091] In addition, the display 20 also includes a flexible circuit board 321 (i.e., a first flexible circuit board) and a flexible circuit board 322 (i.e., a second flexible circuit board). In this embodiment, both flexible circuit boards are electrically connected to the third voltage input terminal and the sixth voltage input terminal respectively via openings OP. However, the invention is not limited thereto. Figure 10As shown, in another embodiment of the display 20A, the first electrode 110C and its voltage input terminal 110in5 can also be disposed on the side of the first substrate 101A away from the display medium layer 200A. Therefore, in this embodiment, the flexible circuit board 321 can be electrically connected to the voltage input terminal 110in5 without extending into the opening OP.

[0092] In addition to the differences mentioned above, due to Figure 8 and Figure 9 The monitor 20 and Figure 10 The other components and their configurations in the display 20A are similar to those in the display 20A. Figure 2 For a detailed description of the display 10, please refer to the relevant paragraphs of the foregoing embodiments, which will not be repeated here.

[0093] Figure 11 This is a top view of the display according to the seventh embodiment of the present invention. Figure 12 yes Figure 11 A cross-sectional view of the display. Figure 12 Corresponding to Figure 11 At section line C-C'. Please refer to... Figure 11 and Figure 12 In the display 30 of this embodiment, the first substrate 101A, the first electrode 110B and the display medium layer 200A have an opening "OP", and this opening "OP" can be located approximately at or near the geometric center of the first substrate 101A.

[0094] Unlike the aforementioned embodiments, the display 30 further includes a light guide structure 410, a light source 420, and a patterned ink layer 430. The patterned ink layer 430 is disposed on the second substrate 102 and overlaps the opening OP". For example, the display 30 may also include a transparent cover plate 410, and the patterned ink layer 430 may be directly printed on the transparent cover plate 410, but is not limited thereto.

[0095] The light guide structure 410 extends into the opening OP and is adapted to guide the light LB from the light source 420 through the patterned ink layer 430. Specifically, the light guide structure 410 may include a light guide plate 411 and a light guide post 413. The light guide post 413 is connected to the light-emitting surface 410es of the light guide plate 411 facing the patterned ink layer 430. The light source 420 is disposed on one side of the light-incident surface 410is of the light guide plate 411 and its light emission can be controlled via a flexible circuit board 450.

[0096] For example, in this embodiment, flexible circuit boards 321A and 322A bonded to the first substrate 101A near the opening OP are optionally electrically connected to the third voltage input terminal (not shown) of the first electrode 110B and / or the sixth voltage input terminal (not shown) of the second electrode 120 via suitable conductive structures (not shown) to achieve a radial gradient effect for displaying grayscale (such as...). Figure 11 (As shown). It should be noted that the configuration of the first electrode 110B and / or the second electrode 120 at the voltage input terminal of the first substrate 101A in this embodiment can also be implemented using any of the aforementioned embodiments. Therefore, please refer to the relevant paragraphs of the foregoing embodiments for detailed descriptions, which will not be repeated here.
