Description

Technical Field

[0001] This utility model relates to the field of electronic paper display technology, and in particular to an electronic paper display device and electronic equipment. Background Technology

[0002] Electronic paper (ePaper) is a novel reflective display technology. Its core technology uses electronic ink to display images and text, achieving a display effect close to traditional paper. It boasts unique advantages such as paper-like display, low power consumption, and eye-friendliness. Major applications of ePaper include e-book readers, electronic tags, educational equipment, smart wearable devices, IoT displays, and advertising and information displays. With continuous technological advancements, the application scenarios of ePaper are expected to expand further, making it one of the important future development directions for display technology.

[0003] Microcavity electronic paper displays (MEDs) primarily involve creating a dam structure on the surface of thin-film transistors (TFTs) to surround each pixel unit. An electronic paste containing black and white particles for imaging is then used to fill the fluid dielectric layer, and finally, the display is encapsulated with a top glass panel. The cavity formed by the multiple dam structures in the MED is thus called the microcavity structure. MEDs can control the color changes of the particles in the electronic paste using an electric field, achieving high contrast, high reflectivity, and a wide color gamut display effect through particle reflection.

[0004] In current electronic paper display devices, there are usually one or two gold dots on the bottom substrate. When the bottom substrate and the top substrate are bonded together, the second conductive layer of the bottom substrate is connected to the first conductive layer of the top substrate through the gold dots, so that the potential of the second conductive layer of the bottom substrate and the first conductive layer of the top substrate are equal. Since there are fewer gold dots on the bottom substrate, there will be a certain resistance between the bottom substrate and the top substrate, which will increase the power consumption of the product. If a continuity abnormality occurs, the electronic paper display device will experience increased resistance or even circuit failure, thus affecting the normal display of the product.

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] It is understood that descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0035] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0036] Firstly, please refer to Figure 1 and Figure 3 , Figure 1 This is a cross-sectional perspective view of the non-display area 16 of an electronic paper display device 100 provided in an embodiment of this application. Figure 2 This is a three-dimensional structural diagram of an electronic paper display device 100 provided in an embodiment of this application. Figure 3 This is a partially enlarged structural schematic diagram of an electronic paper display device 100 provided in an embodiment of this application.

[0037] The present invention provides an electronic paper display device 100, which includes a display area 15 and a non-display area 16, with the non-display area 16 surrounding the display area 15. The electronic paper display device 100 also includes a top substrate 11, a bottom substrate 12, and a frame medium 14. The top substrate 11 and the bottom substrate 12 are correspondingly disposed, and the frame medium 14 is disposed in the non-display area 16 between the top substrate 11 and the bottom substrate 12 to cooperate with the top substrate 11 and the bottom substrate 12 for encapsulation.

[0038] The top substrate 11 includes a first substrate 111 and a first conductive layer 113. The first conductive layer 113 is disposed in the non-display area 16 of the first substrate 111 near the bottom substrate 12, so that the first conductive layer 113 is disposed toward the bottom substrate 12.

[0039] The bottom substrate 12 is disposed opposite to the top substrate 11 and includes a second substrate 121 and a conductive structure 125. The conductive structure 125 is disposed in the non-display area 16 of the second substrate 121 near the top substrate 11 and is disposed corresponding to the first conductive layer 113 of the top substrate 11. The conductive structure 125 includes a via 1251 and a second conductive layer 1252. The via 1251 is disposed in the second substrate 121. One end of the via 1251 is disposed in the second substrate 121 to communicate with at least a portion of the second substrate 121. The other end of the via 1251 is connected to one side of the second conductive layer 1252 so that the second conductive layer 1252 is electrically connected to the second substrate 121 and the interior of the second substrate 121 through the via 1251.

[0040] A bezel medium 14 is disposed in the non-display area 16 between the top substrate 11 and the bottom substrate 12, and is disposed corresponding to the conductive structure 125 and the first conductive layer 113 to connect the first conductive layer 113 of the top substrate 11 and the second conductive layer 1252 of the bottom substrate 12. The bezel medium 14 includes conductive particles 141, so that the bezel medium 14 can have electrical conduction function through the conductive particles 141 therein, so that the first conductive layer 113 can achieve electrical conduction with the second conductive layer 1252 through the conductive particles 141 of the bezel medium 14.

[0041] In one embodiment, the bottom substrate 12 of the non-display area 16 further includes a first insulating layer 126, a second insulating layer 127, a data signal layer 128, and a scan line layer 129. The scan line layer 129 is disposed at one end of the second substrate 121 near the top substrate 11, the second insulating layer 127 is disposed between the data signal layer 128 and the scan line layer 129, and the first insulating layer 126 is disposed at one end of the data signal layer 128 near the top substrate 11. When the conductive structure 125 includes a plurality of vias 1251, one end of at least one via 1251 is connected to the data signal layer 128, and one end of at least one via 1251 is connected to the scan line layer 129.

[0042] By setting the conductive structure 125 around the display area 15, the contact points between the first conductive layer 113 and the second conductive layer 1252 can be increased, making the potentials of the first conductive layer 113 and the second conductive layer 1252 equal. Increasing the contact points reduces the power consumption of the product, and the uniform distribution of the contact points makes the resistance uniform, thereby enhancing the visual effect of the product.

[0043] Please see Figure 4 , Figure 4 This is a cross-sectional perspective view of the display area 15 of an electronic paper display device 100 provided in an embodiment of this application.

[0044] In one embodiment, in the display area 15 of the electronic paper display device 100, the top substrate 11 further includes a first electrode layer 112. The first electrode layer 112 is disposed on the side of the first substrate 111 near the bottom substrate 12, that is, at the same level as the first conductive layer 113, but the two are not connected.

[0045] In one embodiment, in the display area 15 of the electronic paper display device 100, the bottom substrate 12 further includes a driving layer 122, a leveling layer 123, and a second electrode layer 124. The driving layer 122 is connected to the leveling layer 123 and disposed between the second substrate 121 and the conductive structure 125. The driving layer 122 includes a thin film transistor 1221 and is connected to the second substrate 121. The conductive structure 125 is disposed on the side of the leveling layer 123 away from the driving layer 122. The second electrode layer 124 is disposed on the side of the second substrate 121 near the top substrate 11.

[0046] Preferably, the second electrode layer 124 and the second conductive layer 1252 are disposed at the same level, and there is a gap between them to form a gap region. The gap region is arranged in a ring between the second electrode layer 124 and the second conductive layer 1252 to prevent electrical conduction between the second electrode layer 124 and the second conductive layer 1252.

[0047] Furthermore, on the side of the top substrate 11 near the bottom substrate 12, the first electrode layer 112 and the first conductive layer 113 are also disposed at the same level, and there is a gap between them to form a gap region, which is arranged in a ring between the first electrode layer 112 and the first conductive layer 113.

[0048] This configuration, by providing gaps between the second electrode layer 124 and the second conductive layer 1252, and between the first electrode layer 112 and the first conductive layer 113, prevents current conduction between the second electrode layer 124 and the second conductive layer 1252, and between the first electrode layer 112 and the first conductive layer 113, which would affect the output voltage of the second electrode layer 124 to the electronic paste 131 in the filling layer 13, thereby ensuring the stability of the display area 15.

[0049] In one embodiment, the electronic paper display device 100 further includes a filling layer 13 in the display area 15 of the electronic paper display device 100. The filling layer 13 is disposed in the space formed by the top substrate 11, the bottom substrate 12 and the frame medium 14, and is connected to the first electrode layer 112 and the second electrode layer 124. The filling layer 13 includes an electronic paste 131. When the thin film transistor 1221 in the driving layer 122 outputs a voltage through the second electrode layer 124, it drives the electronic paste 131 in the filling layer 13 to be displayed in the display area 15.

[0050] For example, the electronic paste 131 of the filling layer 13 includes a filling liquid and conductive particles. The conductive particles can move relative to each other in the filling liquid. The conductive particles include black particles and white particles with different electrical properties. The second electrode layer 124 controlled by the thin film transistor 1221 cooperates with the first electrode layer 112 to drive the conductive particles in the filling liquid to undergo electrophoresis under the drive of voltage, thereby controlling the movement of the two types of particles, black particles and white particles, and distributing them in different positions in the filling layer 13 so that the electronic paper display device 100 displays different gray levels.

[0051] For example, black and white particles can have different electrical charges. For instance, white particles may carry a negative charge and black particles may carry a positive charge; or white particles may carry a positive charge and black particles may carry a negative charge. No specific limitation is made here.

[0052] In one embodiment, the bottom substrate 12 of the electronic paper display device 100 includes a plurality of conductive structures 125, and the plurality of conductive structures 125 are spaced apart in the non-display area 16 surrounding the display area 15. Each conductive structure 125 includes a second conductive layer 1252 and a plurality of vias 1251, and the plurality of vias 1251 are spaced apart in the second conductive layer 1252.

[0053] With this configuration, by providing multiple conductive structures 125 in the electronic paper display device 100, and providing multiple spaced through holes 1251 in the conductive structures 125, the contact points between the first conductive layer 113 and the second conductive layer 1252 can be increased to improve the conductivity efficiency, and the spaced distribution helps to make efficient and reasonable use of the space of the bottom substrate 12.

[0054] In one embodiment, at least some of the multiple conductive structures 125 are disposed on opposite sides of the display area 15 along a first direction, and the multiple conductive structures 125 on opposite sides of the display area 15 along the first direction are arranged parallel to and spaced apart from the first direction. At least some of the conductive structures 125 are disposed on opposite sides of the display area 15 along a second direction, the first direction and the second direction are perpendicular to each other, and the multiple conductive structures 125 on opposite sides of the display area 15 along the second direction are arranged parallel to and spaced apart from the first direction.

[0055] With this arrangement, multiple conductive structures 125 are arranged parallel to the first direction and the second direction, making the distribution of conductive structures 125 in the bottom substrate 12 more orderly and improving the space utilization of the bottom substrate 12.

[0056] As one embodiment, the first direction and the second direction are perpendicular to each other. For example, the first direction is the Y direction shown in the figure, and the second direction is the X direction shown in the figure.

[0057] In one embodiment, in the conductive structures 125 disposed on opposite sides of the display area 15 along the first direction, the spacing between two adjacent conductive structures 125 in the first direction is equal.

[0058] Furthermore, in the conductive structures 125 disposed on opposite sides of the display area 15 along the second direction, the spacing between two adjacent conductive structures 125 in the second direction is equal.

[0059] In one embodiment, in the conductive structure 125, a plurality of through holes 1251 may be arranged at intervals along a first direction and / or a second direction as needed.

[0060] For example, such as Figure 5 As shown, in all the conductive structures 125, multiple through holes 1251 are arranged at intervals along the first direction.

[0061] For example, such as Figure 6A As shown, in all the conductive structures 125, multiple through holes 1251 are arranged at intervals along the second direction.

[0062] For example, such as Figure 6B As shown, in the conductive structure 125 disposed on opposite sides of the display area 15 along the first direction, a plurality of conductive holes 1251 are arranged at intervals along the second direction. In the conductive structure 125 disposed on opposite sides of the display area 15 along the second direction, a plurality of conductive holes 1251 are arranged at intervals along the first direction.

[0063] For example, such as Figure 6C As shown, in the conductive structure 125 disposed on opposite sides of the display area 15 along the first direction, a plurality of conductive holes 1251 are arranged at intervals along the first direction. In the conductive structure 125 disposed on opposite sides of the display area 15 along the second direction, a plurality of conductive holes 1251 are arranged at intervals along the second direction.

[0064] For example, such as Figures 7A to 7B As shown, in one embodiment, the arrangement of the plurality of through holes 1251 in the conductive structure 125 can be set according to actual needs, and the number of rows of the plurality of through holes 1251 arranged along the first direction and / or the second direction includes, but is not limited to, 1, 2, 3, etc.

[0065] This configuration allows the multiple through holes 1251 in the conductive structure 125 to be arranged in different directions and rows according to actual needs and the actual space of the bottom substrate 12, thereby improving the flexibility of the bottom substrate 12.

[0066] In one embodiment, the second conductive layer 1252 of the conductive structure 125 has a first projection in the third direction perpendicular to the bottom substrate 12, and all the through holes 1251 in the conductive structure 125 have a second projection in the third direction along the bottom substrate 12, wherein at least part of the first projection covers the second projection.

[0067] This configuration ensures that the area of ​​the second conductive layer 1252 on the conductive structure 125 of the bottom substrate 12 is larger than the cross-sectional area of ​​all the through holes 1251 in the conductive structure 125, so that the second conductive layer 1252 can have a larger contact area with the frame medium 14, thereby increasing the contact efficiency between the conductive structure 125 and the conductive particles 141 in the frame medium 14.

[0068] As one embodiment, the third direction is perpendicular to both the first and second directions; for example, the third direction is the Z direction shown in the figure.

[0069] In one embodiment, the frame medium 14 has a third projection formed on the bottom substrate 12 along a third direction, and at least part of the third projection covers the first projection and the second projection.

[0070] This configuration ensures that the frame medium 14 can contact all the conductive structures 125 of the bottom substrate 12, so that all the conductive structures 125 of the bottom substrate 12 can be at the same potential as the first conductive layer 113 through the frame medium 14.

[0071] In one embodiment, the frame medium 14 includes a frame adhesive, and the frame adhesive has a plurality of conductive particles 141, wherein the conductive particles 141 are conductive metals.

[0072] Preferably, the conductive particle 141 is a gold ball, and the maximum diameter of the gold ball is not greater than the diameter of the through hole 1251.

[0073] Please see Figure 8 , Figure 8 This is a schematic diagram of the structure of the electronic device 200 provided in an embodiment of this application.

[0074] Secondly, such as Figure 8 As shown, this utility model also proposes an electronic device 200, which includes an electronic paper display device 100 of any of the above, and the electronic device 200 is used for display through the electronic paper display device 100.
