Therefore, during the assembly of the multi-layer functional layer and the housing, the multi-layer functional layer can occupy more housing space, allowing it to be closer to the edge of the housing, achieving a narrower bezel, and significantly increasing the screen-to-body ratio of the display layer within the multi-layer functional layer, thus meeting the needs of various scenarios and users.

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0038] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this specification should have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms "first," "second," and similar terms used in this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the element or object listed following the word and its equivalents, but do not exclude other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0039] As described in the background section, electronic paper displays are mainly composed of thin-film transistor substrates (TFTs) or plastic substrates, electronic ink films (FPLs) or other ink films, protective films or protective glass, driver ICs, FPCs, system circuit boards, and various coating processes (silver paste, RTV, UV, EC).

[0040] Due to limitations imposed by traditional cutting and packaging processes on TFT substrates, PS, and FPL, conventional electronic paper display (EPD) modules are typically rectangular in design, such as... Figure 1 As shown, it typically has right-angled corners. However, with increasing user demands and market influences, more and more display devices are being designed with irregular shapes, such as those with curved corners, like... Figure 2 As shown, when an electronic paper display (EPD) module with right-angled corners is applied to similar irregularly shaped products, the EPD module cannot be placed close to the edge of the display device, resulting in a large invalid area on the display device, which cannot display anything. This seriously affects the overall screen-to-body ratio of the display device, making the corresponding display device unable to meet current market demands.

[0041] Therefore, in light of the above-mentioned actual situation, this disclosure provides a display device. By determining that one end of the display device's housing has an arc-shaped corner, the multi-layer functional layers used for display are directly processed into multi-layer functional layers with arc-shaped corners that match the arc-shaped corners of the housing during the processing of the multi-layer functional layers for display. In this way, when assembling the multi-layer functional layers with the housing, the multi-layer functional layers can occupy more housing space, making the multi-layer functional layers closer to the edge of the housing, achieving a narrower bezel, and greatly improving the screen ratio of the display layer in the multi-layer functional layers, thus meeting the needs of the scenario and users.

[0042] Figure 3 A schematic diagram of an exemplary display device provided in an embodiment of this disclosure is shown; Figure 7 A schematic diagram of the specific structure of the multi-layer functional layer provided in the embodiments of this disclosure is shown.

[0043] Combination Figure 3 and Figure 7 As shown, a display device 100 according to an embodiment of the present disclosure includes: a housing 110 having an arc-shaped corner 111 at one end; a multi-layer functional layer 120 disposed within the housing 110, wherein a first end 121 of the multi-layer functional layer 120 corresponds to the end of the housing having the corner 111, and the first end 121 has an arc-shaped angle 130 adapted to the corner 111; wherein the multi-layer functional layer 120 includes at least one display layer 127.

[0044] In this embodiment, the housing 110 can be the outer shell structure of the display device 100, mainly used to support other components of the display device 100. Since the housing 110 has arc-shaped corners 111, these corners 111 can exist only at one end of the housing 110, i.e., the included angles on two sides of the rectangular housing are designed as corners 111; or they can exist at both ends of the housing, i.e., all four included angles of the rectangular housing are designed as corners 111. Subsequently, the multi-layer functional layer 120 can generally be fixed inside the housing 110 by means of bonding, etc., and it is mainly used to realize the display function of the display device 100, using structures such as the display layer 127 therein to display and output images. To realize the image display function, the multi-layer functional layer 120 can have multiple levels, with different levels performing different functions, ultimately enabling the display layer 127 to perform display output.

[0045] contrast Figure 2 and Figure 3It can be seen that in order to improve the screen-to-body ratio of the display device 100, the shape and structure of the multi-layer functional layer 120 must be improved to adapt it to the irregularly shaped housing 110. Therefore, for the multi-layer functional layer 120, the end of the multi-layer functional layer 120 corresponding to the end of the housing 110 with the corner 111 can be designed to fit the corner 111. This end of the multi-layer functional layer 120 is referred to as the first end 121. Figure 3 That is, the two included angles of the first end 121 of the multifunctional layer 120 are designed as rounded angles 130 that match the corner 111. This allows the multifunctional layer 120 to be positioned closer to the edge of the housing 111, meaning the first end 121 of the multifunctional layer 120 is closer to the edge, thereby making the multifunctional layer 120 more compact. Figure 2 The ineffective areas in the display can be utilized to increase the screen-to-body ratio. In more specific application scenarios, the cutting and packaging processes of multi-layer functional layers 120, such as thin film transistor substrates (TFT substrates) and front panel liners (FPL), can be adjusted. By using arc-shaped cutting and packaging processes to process multi-layer functional layers 120, they can be made into arc-shaped contours that fit the corresponding display areas, thereby achieving a higher screen-to-body ratio.

[0046] Next, the direction in this embodiment can be defined first, such as... Figure 3 As shown, the lateral direction of the display device 100 can be defined as the first direction X, and the longitudinal direction as the second direction Y. Specifically, in addition to the first end 121, the multi-layer functional layer 120 also has a second end 122 opposite to the first end 121. Therefore, the extension direction of the shortest distance from the first end 121 to the second end 122 or from the second end 122 to the second end 121 of the multi-layer functional layer 120 can be corresponding to the aforementioned second direction Y. The other direction in the plane where the display device 100 is located, which intersects with the second direction Y (specifically, it can be perpendicular, etc.), is the first direction X. The multi-layer functional layer 120 has a third end 123 and an opposite fourth end 124 in the first direction X. Of course, in this embodiment, it is not specifically limited to which end of the multi-layer functional layer 120 the first end 121 to the fourth end 124 is being referred to. In some embodiments, they can be as follows: Figure 3 The third end 123 is located on the left and the fourth end 124 is located on the right. In other embodiments, the third end 123 may be located on the right and the fourth end 124 may be located on the left. The first end 121 and the second end 122 are similar, and are not specifically limited here.

[0047] In some embodiments, such as Figure 3As shown, to secure the multi-layer functional layer 120, at least one fixing hole 140 can be provided at one end of the multi-layer functional layer 120 for further fixation. The fixing hole 140 can be used for fixation by methods such as silver paste injection, adhesive, or even welding and bolts. In specific applications, since the first end 121 of the multi-layer functional layer 120 is already very close to the frame of the housing 110, at least one fixing hole 140 can be provided at the second end 122 opposite to the first end 121, and these fixing holes 140 can be arranged along the first direction X at the second end 122. That is, in some embodiments, the multi-layer functional layer 120 further includes: at least one fixing hole 140, provided at the second end 122 opposite to the first end 121, and arranged along the first direction X at the second end 122, where the first direction X intersects with the second direction Y; wherein, the second direction Y is the extension direction of the shortest distance from the second end 122 to the first end 121 (i.e., the second direction Y).

[0048] Combined Figure 2 and Figure 3 or Figure 4 As shown, if the fixing holes 140 are distributed on one side of the second end 122 (e.g.) Figure 2 As shown), the area where the fixing hole 140 is located will inevitably occupy a certain amount of space in the vertical direction of the entire display device 100, making the display device 100 too long and hindering the size compression of the display device 100. Therefore, as Figure 3 or Figure 4 As shown, the fixing holes 140 can be concentrated on the second end 122, closer to the third end 123 or the fourth end 124, thus leaving the opposite side empty. Here, we take the example of the fixing holes 140 being concentrated on the second end 122, closer to the third end 123. This leaves a certain space on the side of the second end 122 near the fourth end 124, allowing other structures to extend into this part. This reduces the space occupied by other structures in the longitudinal direction of the display device 100, ultimately reducing the overall longitudinal length of the display device 100 and contributing to its miniaturization. Specifically, in some embodiments, the multi-layer functional layer 120 further includes a third end 123 along the first direction X and a fourth end 124 opposite to the third end 123; the at least one fixing hole 140 is located on the second end 122 near the third end 123 and away from the fourth end 124.

[0049] Furthermore, in some embodiments, a control unit 150 for performing functions such as signal generation may also be provided for the display device 100. For example... Figure 3 or Figure 4As shown, based on the same or similar utilization as the fixing hole 140, the control unit 150 can also be positioned near one side of the second end 122 of the multi-layer functional layer 120, for example, near the third end 123. Specifically, it can be as follows... Figures 3 to 5 As shown, the control unit 150 is disposed beside the fixing hole 140. That is, in some embodiments, the display device 100 further includes: a control unit 150 disposed beside the at least one fixing hole 140, close to the third end 123 and far from the fourth end 124.

[0050] Furthermore, to facilitate the placement of the control unit 150 and prevent it from occupying excessive vertical space of the display device 100, the control unit 150 can be positioned between multiple mounting holes. For example, in an embodiment with two mounting holes 140, as shown... Figure 3 As shown, the control unit 150 can be positioned between the two fixing holes 140, either centrally or off-center. That is, in some embodiments, the at least one fixing hole 140 includes two fixing holes 140, and the control unit 150 is located between the two fixing holes 140.

[0051] In other embodiments, to further simplify the structure and taking advantage of advancements in current fixing technology, only one fixing hole 140 is needed to meet the requirements. Furthermore, as... Figure 4 or Figure 5 As shown, a fixing hole 140 can be provided on the edge of the second end 122 (e.g. Figure 4 It can also be a slightly more central position (such as...) Figure 5 At this time, the control unit 150 can be disposed on one side of the fixing hole 140 (e.g., Figure 4 Alternatively, it can be positioned on both sides of the fixing hole 140 (e.g.) Figure 5 In embodiments where the control unit 150 is disposed on both sides of the fixing hole 140, the control unit 150 located on both sides of the fixing hole 140 can be a single unit or two independent units, which can be configured according to specific scenario requirements. That is, in some embodiments, the at least one fixing hole 140 includes one fixing hole 140, and the control unit 150 is located on one side of the one fixing hole 140 or on both sides of the one fixing hole 140.

[0052] In some embodiments, for the display device 100, such as Figure 4 or Figure 5As shown, a flexible circuit board 160 for signal transmission and other functions can also be provided. The flexible circuit board 160 can be connected to the multi-layer functional layer 120 via a flexible ribbon cable 170. In some specific application scenarios, the flexible circuit board 160 can be a PCB substrate, and the flexible ribbon cable 170 can be an FPC line. That is, in some embodiments, the display device 100 further includes: a flexible circuit board 160 disposed on the side of the housing 110 away from the first end 121 of the multi-layer functional layer 120, and connected to the multi-layer functional layer 120 via the flexible ribbon cable 170.

[0053] Furthermore, regarding the placement of the flexible circuit board 160, in conjunction with the aforementioned example of placing the fixing hole 140 and other structures on one side of the second end 122, in some display devices 100 without other structures, a portion of the flexible circuit board 160 can be inserted into the portion left empty by the fixing hole 140 and other structures, thereby reducing the overall longitudinal length of the display device 100. For example... Figure 4 As shown, the boundary of the flexible circuit board 160 facing the multilayer functional layer 120 is divided into a continuous first segment 161 and a second segment 162. The first segment 161 corresponds to the area where the fixing hole 140 is located, near the third end 123; while the second segment 162 directly corresponds to the multilayer functional layer 120, near the fourth end 124. It can be seen that the second segment 162 is closer to the multilayer functional layer 120 than the first segment 161, thus allowing a portion of the flexible circuit board 160 structure to extend into the area originally occupied by the fixing hole 140, reducing the overall vertical length of the display device 100. In more specific application scenarios, such as... Figure 4 The display device 100 shown can be specifically applied to projects such as name tags and price tags. By increasing the placement space of the flexible circuit board 160, a narrower protrusion and device length can be achieved. That is, in some embodiments, the boundary of the flexible circuit board 160 facing the multilayer functional layer 120 includes a first segment 161 and a second segment 162 continuous with the first segment 161; the first segment 161 corresponds to the area where the at least one fixing hole 140 is located and is close to the third end 123; the second segment 162 corresponds to the multilayer functional layer 120 and is close to the fourth end 124; the second segment 162 is closer to the multilayer functional layer 120 than the first segment 161.

[0054] In other embodiments, such as Figure 5As shown, if the display device 100 also needs to be provided with other functional areas 170, for example, if the display device 100 is a certain kind of mobile phone case, then the display device 100 also needs to be provided with a camera hole corresponding to the mobile phone camera; or control buttons, buttons and other function key structures can be provided on the display device 100. Of course, in some embodiments, the functional area 170 can include multiple functions, such as the aforementioned camera hole and control buttons being provided in the functional area 170. The functional area 170 can be set side by side with the flexible circuit board 160, and the functional area 170 can be made closer to the fourth end 124, so that the part vacated by the aforementioned fixing hole 140 and other structures can be used to provide a certain setting space for the functional area 170, which can also reduce the overall vertical length of the display device 100. It should be noted that although the functional area 170 and the flexible circuit board 160 can be set side by side, it does not mean that the two must be aligned with each other. The specific setting position of the two can be adjusted according to the specific application scenario, only ensuring that the two are side by side, simply put, one is set on the left and the other on the right. That is, in some embodiments, the display device 100 further includes: a functional area 170 disposed on the side of the housing 110 away from the first end 121 of the multilayer functional layer 120; wherein the flexible circuit board 160 is disposed side by side with the functional area 170, the flexible circuit board 160 being closer to the third end 123, and the functional area 170 being closer to the fourth end 124. Furthermore, in some embodiments, the functional area 170 may specifically include a camera hole area and / or a function key area.

[0055] In some embodiments, the specific structural form of the fixing hole 140 can be set according to the specific application scenario, such as... Figure 6 As shown, the shape of the fixing hole 140 can be circular, elliptical, semi-circular, etc.; and the fixing hole 140 can protrude outward from the multi-layer functional layer 120 or be embedded in the multi-layer functional layer 120. Furthermore, in some embodiments, compared to a circular fixing hole 140, an elliptical or semi-circular fixing hole 140 can have a narrower protruding or embedded area, thereby further increasing the area range of other structures. That is, in some embodiments, the at least one fixing hole 140 is disposed on the side of the second end 122 away from the first end 121, or disposed on the side of the second end 122 close to the first end 121.

[0056] In some embodiments, for the multi-layer functional layer 120, such as Figure 7As shown, it can further include a driving function layer 129, a spacer layer 128, a display layer 127, and a display border 126. The specific display area is located at position 125 in the figure, i.e., display area 125. Regarding the display layer 127 and display area 125, the display layer 127 is used to generate the image, while the actual area available for display is determined by the display area 125. The display area 125 is generally smaller than the display layer 127, which allows for greater tolerance of the display layer 127. For example, some minor defects at the edges of the display layer 127 can be ignored, or a certain degree of error can be allowed during the bonding process. The display border 126 is mainly used to define the range of the display area 125 and provides some support. These layers can be stacked sequentially in a direction away from the housing 110. These layers can be bonded together using the same or different adhesives. Using different adhesives can also produce other effects; for example, EC adhesive (epoxy resin thermosetting adhesive) can be applied around the edges of the display layer 127 to seal and prevent moisture. These structures enable all or part of the functions of the multi-layer functional layer 120, and the display layer 127 is used to complete the image display output. Specifically, in some embodiments, the multi-layer functional layer 120 includes a driving functional layer 129, a spacer layer 128, the display layer 127, and a display bezel 126, stacked sequentially along the direction away from the housing.

[0057] Then, considering the structural support between each level, in order to prevent the upper levels from collapsing due to lack of effective support, by... Figure 7 A magnified view of the inner circle reveals that the aforementioned layers can be sequentially reduced in size along the direction away from the shell, meaning the projected area of ​​each layer on the shell gradually decreases. This allows the lower layers to effectively provide support for the upper layers, preventing other unnecessary problems. Specifically, as shown... Figure 7 As shown, the driving functional layer 129 is located at the bottom and has the largest area; above it is the spacer layer 128, which has the next largest area; then comes the display layer 127, which has the next largest area; then comes the display border 126, which has the next smallest area; and at the top is the display area 125, which has the smallest area. That is, in some embodiments, the projected area of ​​each layer of the multi-layer functional layer 120 on the housing 110 gradually decreases and / or gradually shrinks towards the center of the housing 110 in a direction away from the housing 110.

[0058] In more specific applications, the display layer 127 can be an electronic ink film or electronic paper (FPL). Electronic paper is a paper-like electronic display characterized by its thinness, flexibility, and erasability. Subsequently, the driving functional layer 129 can include an array of multiple driving circuits, each including at least one thin-film transistor (TFT). A thin-film transistor is an insulated-gate field-effect transistor that operates by controlling the gate voltage to regulate the current between the source and drain. The basic structure of a TFT includes a substrate, a buffer layer, an active layer (semiconductor layer), a gate insulating layer, a gate, a source, and a drain. That is, in some embodiments, the display layer 127 comprises an electronic ink film or electronic paper; and / or the driving functional layer 129 comprises an array of multiple driving circuits, each including at least one thin-film transistor.

[0059] As can be seen from the above description, the present disclosure provides a display device comprising: a housing with an arc-shaped corner at one end; and a multi-layer functional layer disposed within the housing, wherein a first end of the multi-layer functional layer corresponds to the end of the housing with the arc-shaped corner and has an arc-shaped angle adapted to the corner; wherein the multi-layer functional layer includes at least one display layer. The present disclosure, by determining that one end of the housing of the display device has an arc-shaped corner, directly processes the multi-layer functional layer for display into a multi-layer functional layer with an arc-shaped angle adapted to the arc-shaped corner of the housing during the processing of the multi-layer functional layer for display. Therefore, during the assembly of the multi-layer functional layer and the housing, the multi-layer functional layer can occupy more housing space, allowing it to be closer to the edge of the housing, achieving a narrower bezel, and significantly increasing the screen-to-body ratio of the display layer within the multi-layer functional layer, thus meeting the needs of various scenarios and users.

[0060] It is understandable that the display device is a product with image display function, and it is generally driven by multiple driving circuits. In addition, this product generally uses electronic thin film (i.e. electronic paper) technology. Therefore, the display device can be: small billboard, price tag, label, name tag, mobile phone case, simple entertainment product, etc.

[0061] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of this disclosure (including the claims) is limited to these examples; within the scope of this invention, technical features of the above embodiments or different embodiments can also be combined, and many other variations of different aspects of this invention as described above exist, which are not provided in the details for the sake of brevity. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.
