Description

Technical Field

[0001] This utility model relates to the field of electronic display technology, and further to an electronic paper film and an electronic paper screen, particularly to an electronic paper film and an electronic paper screen that can optimize layout and reduce costs. Background Technology

[0002] Electronic paper screens are displays made using electrophoretic display technology. They achieve image display by applying driving voltages to each pixel through control circuitry on a TFT (thin-film transistor) substrate. As a reflective display, electronic paper screens can maintain the displayed image for a long time without continuous refreshing after an image is updated, resulting in very low power consumption. Due to its many advantages, including low power consumption, wide viewing angle, high contrast, and eye-friendly design, electronic paper screens are increasingly widely used in electronic price tags, e-books, and billboards.

[0003] Electronic paper screens use electronic paper films as display units to present images as seen by the human eye. For example... Figures 1 to 3 As shown, based on the function of the electronic paper film 200, it can be divided into a display function area and an electrical connection function area: 1. The display function area covers the display area of ​​the electronic paper screen 100, which includes an AA area (Active Area) 300 and a Border area 400. The required image information is displayed according to the voltage timing of the pixel electrodes of the AA area 300 and the Border electrodes of the Border area 400. The display area of ​​the existing electronic paper screen 100 is usually rectangular, and the corresponding AA area 300 of the electronic paper film 200 is also rectangular. 2. The electrical connection function area is usually located outside the display area of ​​the electronic paper screen 100, on one or both sides of the upper or lower edge of the electronic paper screen 100. It is used to set electrical connection points 700. Ag glue dots are formed by applying Ag glue to the electrical connection points 700, and then the common electrode (e.g., VCOM electrode) on the TFT driving substrate is connected to the electrode (e.g., VCOM electrode) on the electronic paper film 200 by applying Ag glue. The ITO electrodes are connected to the electronic paper film to drive and control the electrodes on the electronic paper film; the shape of the electrical connection functional area is usually rectangular (approximately 4*4mm in size).

[0004] From the above content, it can be seen that, Figures 1 to 5As shown, the electrical connection functional area of ​​the electronic paper film 200 is usually located on the left and / or right side of the upper edge of the display functional area, or on the left and / or right side of the lower edge of the display functional area, and has a round hole (also called an ear hole 500) for applying Ag glue. However, the presence of the ear hole 500 causes the electronic paper film 200 to have a convex area (the area where the ear hole 500 is convex) 600 in its shape, resulting in an irregular shape of the electronic paper film 200. This will prevent the electronic paper film 200 from being arranged tightly in the layout, and there will inevitably be a waste of the ineffective area 800, which will reduce the number of cuts and utilization rate of the electronic paper film 200 and increase the material cost.

[0005] like Figure 3 As shown, from left to right, the diagram illustrates the outline of the electronic paper film 200, a reference rectangle distinguishing the functional areas of the electronic paper film 200, and the overlapping area of ​​the electronic paper film 200 and the reference rectangle. It can be seen that the overlapping pattern of the electronic paper film 200 and the reference rectangle can be divided into region 1 and region 2. Region 1 is where the electronic paper film is positioned above area AA 300 and border area 400 (i.e., the area covering area AA 300 and border area 400), which is the display functional area of ​​the electronic paper film 200. This area is rectangular, as shown... Figure 3 As shown, the horizontal dimension of the rectangle can be set as X, and the vertical dimension can be set as Y; Region 2 is the protruding region 600 of the electronic paper film 200 located outside the AA region 300 and the Border region 400, used to set the electrical connection points (i.e., Ag adhesive dots) 700, which is also the electrical connection functional area where the ear hole 500 is located on the electronic paper film 200. This can be described using the rectangular region 2, and the horizontal dimension of this protruding region 600 is set as x1, and the vertical dimension as y1. Under this shape of the electronic paper film 200, as... Figure 4 and Figure 5 As shown, two common layout methods for this type of electronic paper film are illustrated, with a 2x2 electronic paper film array as an example. For instance... Figure 4 In the layout method 1 shown, the electronic paper film 200 is arranged in parallel both horizontally and vertically. Due to the presence of electrical connection points 700 and protruding areas 600, there are invalid areas 800 among multiple electronic paper films 200, the same number as the number of electronic paper films 200. The area of ​​the invalid area 800 corresponding to each electronic paper film 200 is (X-x1)*y1; while in... Figure 5In layout method 2 shown, compared to layout method 1, in the vertical direction, one of the two adjacent electronic paper films 200 is rotated 180° before being placed. At this time, the two adjacent electronic paper films 200 share an invalid area 800. The number of invalid areas 800 between multiple electronic paper films 200 is half the number of electronic paper films 200. The area of ​​the invalid area 800 corresponding to each electronic paper film 200 is (X / 2-x1)*y1.

[0006] It can be seen that for an electronic paper film 200 with a single ear hole 500, the above-mentioned layout method 2 can effectively reduce the invalid area 800 in the layout compared to layout method 1. However, for an electronic paper film 200 with two ear holes 500, regardless of the layout method used, the number of invalid areas 800 and the area of ​​the invalid area 800 corresponding to each piece of electronic paper film 200 are the same. As can be seen from the above, due to the presence of the ear holes 500 and the protruding area 600 on the electronic paper film 200, there are a large number of invalid areas 800 in the layout of the electronic paper film 200. These invalid areas 800 are discarded as waste during the cutting process of the electronic paper film 200, which leads to a decrease in the number of cuts and utilization rate of the existing electronic paper film 200 in the layout and cutting process, and an increase in material costs.

[0007] Therefore, optimizing the shape of electronic paper film and electronic paper screen to eliminate the impact of the protruding area of ​​the ear hole on the overall electronic paper film, achieve a tight arrangement of electronic paper film, reduce or even eliminate the waste of electronic paper film caused by ineffective areas, thereby increasing the number of electronic paper film cuts and utilization rate and reducing the material cost of electronic paper film, has become an urgent problem to be solved.

[0008] Therefore, this application proposes an electronic paper film and an electronic paper screen to solve at least one of the above-mentioned technical problems. Utility Model Content

When the electronic paper film has a protruding part for setting electrical connection points, a corresponding notch area is set on the electronic paper film. During layout, the protruding part is accommodated by the cooperation of the notch areas on one or more electronic paper films. This achieves a tight arrangement of multiple electronic paper films while eliminating unnecessary and ineffective areas, effectively increasing the number of electronic paper films that can be cut and the utilization rate, and solving the problems of waste and increased costs caused by cutting electronic paper films.

[0093] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0094] It should be noted that when an element is referred to as being "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only embodiments.

[0095] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0096] like Figures 6 to 40As shown, this utility model provides an electronic paper film, which includes a main body portion 1 and at least one protruding portion 2. The main body portion 1 is used to form the display function area 101 of the electronic paper screen. The protruding portion 2 is connected to the main body portion 1 and protrudes from the main body portion 1 (wherein, protruding from the main body portion 1 means that the protruding portion 2 extends outward along the edge of the main body portion 1 and protrudes from the outside of the main body portion 1). The protruding portion 2 is used to set the electrical connection point (such as Ag glue dot 3) of the electronic paper screen. At least one notch area 102 is formed in the main body portion 1. The notch area 102 is adapted to the protruding portion 2. When multiple electronic paper films are in a state of joint splicing and layout, the notch area 102 on one electronic paper film accommodates at least part of the protruding portion 2 on another electronic paper film.

[0097] In this invention, the electronic paper film has at least a main body portion 1 and an outwardly protruding portion 2. The main body portion 1 forms the display function area 101 of the electronic paper screen, which is used to implement the display function. The outwardly protruding portion 2, which is used to set the electrical connection point 3, protrudes from the main body portion 1 (protruding means extending outward along the edge of the main body portion). To accommodate the outwardly protruding portion 2, this application forms a corresponding notch area 102 on the main body portion 1. When multiple electronic paper films are spliced ​​and arranged, the notch area 102 accommodates at least part of the outwardly protruding portion 2 of another electronic paper film. This allows multiple electronic paper films to be arranged tightly while the outwardly protruding portion 2 on the electronic paper film is accommodated in the layout after the multiple electronic paper films are arranged. There is no need to cut the excess part of the electronic paper film because of the outwardly protruding portion 2. This not only eliminates the invalid area left after the layout due to cutting, but also makes the arrangement of multiple electronic paper films more compact and has better overall integrity. It also effectively improves the utilization rate of the electronic paper film and solves the problems of waste and increased cost caused by cutting the electronic paper film.

[0098] In some optional embodiments of this utility model, the area of ​​the notch region 102 is greater than or equal to the area of ​​the protruding portion 2. When multiple electronic paper films are in a splicing and layout state, the notch region 102 on one electronic paper film is used to accommodate the protruding portion 2 on another adjacent electronic paper film.

[0099] Furthermore, each electronic paper film has one protruding portion 2 and one notch area 102, which are located at the top corner or edge of the electronic paper film.

[0100] Specifically:

[0101] In one optional embodiment of this utility model, such as Figure 6 and Figure 9As shown, the display function area 101 of the electronic paper screen includes an effective display area (i.e., area AA) 1011 and a border area (i.e., border area) 1012 surrounding the effective display area 1011. Both the effective display area 1011 and the border area 1012, which are positioned opposite to the main body 1 of the electronic paper film, have notched areas 102. Specifically, as shown... Figure 6 As shown, the upper left corner of the main body 1 of the electronic paper film has a notch area 102, and the effective display area 1011 and the border area 1012 of the electronic paper film and the electronic paper screen also have the notch area 102; Figure 9 As shown, a notch area 102 is located at the lower right corner of the main body 1 of the electronic paper film, and the effective display area 1011 and the border area 1012 of the electronic paper film and the electronic paper screen also have notch areas 102. At this notch area 102, the effective display area 1011 of the electronic paper screen, the border area 1012, and the main body 1 of the electronic paper film are all recessed to form a notch. Considering the convenience of sealing the edge of the electronic paper screen with adhesive and applying the protective film (i.e., PS: Polystyrene), and from the perspective of the cost of the protective film, the notch treatment of the protective film's shape is not required (i.e., the notch area 102 is not formed on the protective film). Of course, in the actual product manufacturing process, the notch area 102 can also be formed on the protective film as needed; whether or not the notch area 102 is formed on the protective film is not limited here.

[0102] In one optional embodiment of this utility model, such as Figures 6 to 8 As shown, the electronic paper film has a rectangular sheet structure or a generally rectangular sheet structure, with one protruding portion 2 and one notch area 102 on each electronic paper film; in the width direction of the electronic paper film (e.g. Figure 7 In the X direction (as shown in the image), the convex portion 2 and the notch region 102 are located on the same side of the main body portion 1; in the height direction of the electronic paper film (e.g., in the X direction), the convex portion 2 and the notch region 102 are located on the same side of the main body portion 1; Figure 7 In the Y direction (as shown in the image), the convex portion 2 is located at the bottom apex corner of the main body portion 1, and the notch region 102 is located at the top apex corner of the main body portion 1. Of course, as... Figure 14 As shown, the protruding part 2 may be located at the top corner of the main body part 1, and the notch area 102 may be located at the bottom corner of the main body part 1.

[0103] In this embodiment, as Figure 9As shown, when multiple electronic paper films are in a spliced ​​layout state, the edges of two adjacent electronic paper films can fit tightly together in the width direction; while in the height direction, the protruding part 2 on one electronic paper film is accommodated in the notch area 102 on the other electronic paper film, thereby effectively avoiding the generation of unnecessary invalid areas.

[0104] In this embodiment, as Figures 7 to 9 As shown, the overlapping pattern of the electronic paper film and the set reference rectangle can be divided into three regions. Region 1 is the effective display area 1011 and the border area 1012 covered by the electronic paper film, which is the display function area 101 of the electronic paper film. The shape of this region is a notched rectangle with a concave upper left corner (i.e., notched area 102). The maximum dimension of this notched rectangle in the width direction (i.e., the X direction) of the electronic paper film is set to X, and the maximum dimension in the height direction (i.e., the Y direction) of the electronic paper film is set to Y. Region 2 is located outside the effective display area 1011 and the border area 1012 of the electronic paper film. It is the protruding part 2 used to set the electrical connection point 3, which is the electrical connection function area (ear hole area) of the electronic paper film. Here, we take the rectangular region 2 as an example. The dimension of this rectangle in the width direction of the electronic paper film is set to x1, and the dimension in the height direction of the electronic paper film is set to y1. Region 3 is the notched area 102 set vertically opposite to region 2. Region 3 is used to set the notched area 102. Figure 9 The translation layout shown accommodates the protruding portions 2 of adjacent electronic paper films in the height direction, i.e., the notch area 102 of the electronic paper film. Here, a rectangular area 3 is used as an example. The dimension of this rectangle in the width direction of the electronic paper film is set as x1, and its dimension in the height direction is set as y1. By setting a reference rectangle with dimensions X and Y in the width direction of the electronic paper film, and aligning the boundaries of the reference rectangle and the electronic paper film, the various functional areas of the electronic paper film can be visually distinguished. For example... Figure 7 and Figure 8 As shown, assuming the set of regions of the electronic paper film is R_FPL, the set of regions of the reference rectangle is R_ref, the set of regions of region 1 is R_1, the set of regions of region 2 is R_2, and the set of regions of region 3 is R_3, then R_1 = R_FPL ∩ R_ref, R_2 = R_FPL - R_ref, and R_3 = R_ref - R_FPL. That is, R_1 is the intersection of R_FPL and R_ref, R_2 is the difference between R_FPL and R_ref, and R_3 is the difference between R_ref and R_FPL.

[0105] And by Figure 8It can be seen that: Region 2 and Region 3 have completely identical shapes, and their edges completely overlap; Electrical connection points 3 are located in Region 2, and all of them are located inside Region 2, with no overlap between the outer edges of the electrical connection points 3 and the outer edges of Region 2. However, due to... Figure 9 It can be seen that: multiple electronic paper films are arranged in a translational layout. Since each electronic paper film has a protruding part 2 and a notch area 102, the edges of two adjacent electronic paper films can fit tightly in the width direction of the electronic paper film, and there is no invalid area.

[0106] In another optional embodiment of this utility model, such as Figures 10 to 13 As shown, the electronic paper film has a rectangular sheet structure or a generally rectangular sheet structure, and each electronic paper film has one protruding portion 2 and one notch area 102; in the height direction of the electronic paper film (e.g. Figure 11 In the Y direction (as shown in the image), the convex portion 2 and the notch region 102 are located on the same side of the main body portion 1; in the width direction of the electronic paper film (e.g., in the Y direction), the convex portion 2 and the notch region 102 are located on the same side of the main body portion 1; Figure 11 In the X direction (of the main body 1), the convex portion 2 and the notch region 102 are located at the two opposite corners of the bottom of the main body 1. Alternatively, the convex portion 2 and the notch region 102 can be located at the two opposite corners of the top of the main body 1.

[0107] In this embodiment, as Figure 13 As shown, when multiple electronic paper films are in a splicing and layout state, the edges of two adjacent electronic paper films are tightly attached in the width direction; while in the height direction, the protruding parts 2 on the two adjacent electronic paper films are respectively accommodated in the notch area 102 of the other, thereby effectively eliminating the generation of unnecessary invalid areas.

[0108] In this embodiment, as Figures 11 to 13As shown, the overlapping shape of the electronic paper film and the set reference rectangle can be divided into three regions. Region 1 is the electronic paper film covering the effective display area 1011 and the border area 1012, which is the display function area 101 of the electronic paper film. The shape of this region is a notched rectangle with a concave lower right corner (i.e., notched area 102). The maximum dimension of this notched rectangle in the width direction (i.e., the X direction) of the electronic paper film is set to X, and the maximum dimension in the height direction (i.e., the Y direction) of the electronic paper film is set to Y. Region 2 is located outside the effective display area 1011 and the border area 1012 of the electronic paper film. It is the protruding part 2 used to set the electrical connection point 3, which is the electrical connection function area (ear hole area) of the electronic paper film. Here, we take the rectangular region 2 as an example. The dimension of this rectangle in the width direction of the electronic paper film is set to x1, and the dimension in the height direction of the electronic paper film is set to y1. Region 3 is the notched area 102 set opposite to region 2 in the horizontal direction. Region 3 is located at the lower right corner, and region 2 is located at the lower left corner. Compared with the translation layout method, the electronic paper film in this embodiment is as follows: Figure 13 As shown, region 3 is used to accommodate the protruding portions 2 of two adjacent electronic paper films in the height direction of the electronic paper film, i.e., the notch area 102 of the electronic paper film, in a relative layout method that is rotated 180° based on translation layout. Here, we will use a rectangular region 3 as an example. Let the dimension of this rectangle in the width direction of the electronic paper film be x1 and the dimension in the height direction of the electronic paper film be y1. By setting a reference rectangle with a dimension of X in the width direction of the electronic paper film and a dimension of Y in the height direction of the electronic paper film, and aligning the boundary of the reference rectangle with the boundary of the electronic paper film, the various functional areas of the electronic paper film can be intuitively distinguished. Figure 11 and Figure 12 As shown, assuming the set of regions of the electronic paper film is R_FPL, the set of regions of the reference rectangle is R_ref, the set of regions of region 1 is R_1, the set of regions of region 2 is R_2, and the set of regions of region 3 is R_3, then R_1 = R_FPL ∩ R_ref, R_2 = R_FPL - R_ref, and R_3 = R_ref - R_FPL. That is, R_1 is the intersection of R_FPL and R_ref, R_2 is the difference between R_FPL and R_ref, and R_3 is the difference between R_ref and R_FPL.

[0109] And by Figure 12 It can be seen that region 2 of the electronic paper film has the same shape as region 3 after it has been rotated 180°, and the edges of the two regions completely overlap. Electrical connection points 3 are located in region 2, and all electrical connection points 3 are located inside region 2; the outer edges of electrical connection points 3 do not overlap with the outer edges of region 2. And from... Figure 13It can be seen that: multiple electronic paper films are arranged in a relative manner. Since each electronic paper film has a protruding part 2 and a notch area 102 respectively, the edges of two adjacent electronic paper films can fit tightly in the width direction of the electronic paper film, and there is no invalid area.

[0110] In the above embodiment, the example given is that region 2, where electrical connection point 3 is located, is situated at the lower left corner of region 1. In actual products, regions 2 and 3 can also be located at any of the two ends of the four edges of region 1 (top, bottom, left, and right), without limitation. Figure 14 As shown, region 2 is located in the upper left corner of region 1, while region 3 is located in the lower left corner of region 1.

[0111] In some optional embodiments of this utility model, the notch area 102 is a rectangular area, and the protruding portion 2 is a rectangular protruding portion or a non-rectangular protruding portion. For example... Figures 6 to 15 As shown, when the notch region 102 is a rectangular region, and the convex portion 2 is also a rectangular protrusion, the area of ​​the convex portion 2 is less than or equal to the notch region 102, and the convex portion 2 is entirely contained within the notch region 102. Even with the close arrangement of multiple electronic paper films, the convex portion 2 on one electronic paper film is entirely contained within the notch region 102 on the adjacent electronic paper film, thus achieving the purpose of eliminating invalid areas. And as... Figures 16 to 19 As shown, when the notch area 102 is a rectangular area and the convex part 2 is a non-rectangular protrusion, as long as the area of ​​the convex part 2 is smaller than the notch area 102 and the convex part 2 is fully contained within the notch area 102, the convex part 2 on one electronic paper film can be fully contained within the notch area 102 on the adjacent electronic paper film when multiple electronic paper films are arranged closely, thus achieving the purpose of eliminating invalid areas.

[0112] In this embodiment, as Figures 17 to 18As shown, the overlapping pattern of the electronic paper film and the set reference rectangle can be divided into three regions. Region 1 is the electronic paper film covering the effective display area 1011 and the border area 1012, which is the display function area 101 of the electronic paper film. The shape of this region is a notched rectangle with a concave upper left corner (i.e., notched area 102). The maximum dimension of this notched rectangle in the width direction (i.e., the X direction) of the electronic paper film is set to X, and the maximum dimension in the height direction (i.e., the Y direction) of the electronic paper film is set to Y. Region 2 is located outside the effective display area 1011 and the border area 1012 of the electronic paper film. It is the protruding part 2 used to set the electrical connection point 3, which is the electrical connection function area (ear hole area) of the electronic paper film. Although this region 2 is not a rectangular area, its size can be set with the smallest rectangular area that can accommodate this region 2. That is, the dimension of this region 2 in the width direction of the electronic paper film is set to x1, and the dimension in the height direction of the electronic paper film is set to y1. Region 3 is the notched area 102 set vertically opposite to region 2. Region 3 is used for setting the notched area 102 in the upper left corner. Figure 19 The translation layout shown includes the convex portion 2 of the adjacent electronic paper film in the height direction, i.e., the notch area 102 of the electronic paper film. Here, a rectangular area 3 is used as an example. This rectangular area can be the same size as or larger than the smallest rectangular area accommodating the notch area 102. The dimension of this rectangle in the width direction of the electronic paper film is set to x2 (x2 ≥ x1), and the dimension in the height direction of the electronic paper film is set to y2 (y2 ≥ y1). By setting a reference rectangle with dimensions X and Y in the width direction of the electronic paper film, and aligning the boundary of the reference rectangle with the boundary of the electronic paper film, the various functional areas of the electronic paper film can be visually distinguished. From... Figure 18 As can be seen, region 2 is a polygonal region composed of straight lines and arcs. Electrical connection points 3 are located within region 2, and all of 3 are situated inside the region, with no overlap between their outer edges and the outer edge of region 2. Region 3 is a rectangular notch region 102, which can accommodate the polygonal region of region 2. In other words, the shape of region 3 is larger than that of region 2, and the area of ​​region 3 completely covers the area of ​​region 2. Figure 19It can be seen that: when multiple electronic paper films are arranged in a translational layout, since each electronic paper film has a protruding part 2 and a notch area 102 respectively, the edges of two adjacent electronic paper films can fit tightly in the width direction of the electronic paper film. In the width direction of the electronic paper film, the notch area 102 of two adjacent electronic paper films is larger than the protruding part 2, and the protruding part 2 can be completely accommodated within the notch area 102. Although the area where the notch area 102 of two adjacent electronic paper films is larger than the protruding part 2 is an invalid area, since the area of ​​this invalid area is very small, it will not affect the number and method of the multiple electronic paper films, the utilization rate of the electronic paper films, or the material cost. Therefore, the full utilization of the electronic paper films can also be achieved.

[0113] It should be noted that the shapes of the notch area 102 and the protruding portion 2 corresponding to the electronic paper film are not limited. Both the notch area 102 and the protruding portion 2 can be rectangular; alternatively, they can have the same shape and be non-rectangular. The shapes of the notch area 102 and the protruding portion 2 can be, but are not limited to, triangles, circles, ellipses, semicircles, semi-ellipses, sectors, or polygons. Polygons include, but are not limited to, polygons composed of straight lines, polygons composed of arcs, and polygons composed of a combination of straight lines and arcs. Examples are provided below.

[0114] Depend on Figure 20 As can be seen, the electronic paper film has a protruding portion 2 at the bottom left corner, which is triangular in shape. An electrical connection point 3 is located on this protruding portion 2, and the electrical connection point 3 can also be triangular in shape. Corresponding to the protruding portion 2, a notch area 102 is located at the top left corner of the electronic paper film. Figure 20 The missing corner area 102 is shaped like a triangle that matches the convex part 2.

[0115] Depend on Figure 21 As can be seen, the electronic paper film has a convex portion 2 at the bottom left corner, which is fan-shaped. An electrical connection point 3 is located on this convex portion 2, and the electrical connection point 3 can also be fan-shaped. Corresponding to the convex portion 2, a notch area 102 is located at the top left corner of the electronic paper film. Figure 20 The missing corner area 102 is fan-shaped to match the convex part 2.

[0116] In actual products, appropriate shapes can be selected as needed, and are not limited to the triangles or sectors mentioned above, while specific sizes and shapes are not limited here.

[0117] In one optional embodiment of this utility model, such as Figure 22 and Figure 23 As shown, the protruding portion 2 is located at the top center of the main body portion 1, and the notch area 102 is located at the bottom center of the main body portion 1. Alternatively, the protruding portion 2 can be located at the bottom center of the main body portion 1, and the notch area 102 at the top center of the main body portion 1. When multiple electronic paper films are spliced ​​and arranged, in the width direction of the electronic paper films, the edges of adjacent electronic paper films are tightly fitted; while in the height direction of the electronic paper films, in two adjacent electronic paper films, the protruding portion 2 on one electronic paper film is accommodated within the notch area 102 on the other electronic paper film, and there are no invalid areas.

[0118] Depend on Figure 22 It can be seen that: a convex portion 2 is provided at the middle position of the top edge of the electronic paper film. This convex portion 2 is a polygon composed of straight lines and arcs, and an electrical connection point 3 is provided in this convex portion 2. The electrical connection point 3 is circular in shape. Corresponding to the convex portion 2, a notch area 102 is provided at the middle position of the bottom edge of the electronic paper film. Figure 22 The recessed area, specifically the notch area 102, is also a polygon composed of straight lines and arcs. Figure 23 It can be seen that: a convex portion 2 is provided at the middle position of the top edge of the electronic paper film. This convex portion 2 is semi-circular, and an electrical connection point 3 is provided in this convex portion 2. The electrical connection point 3 is also semi-circular in shape. Corresponding to the convex portion 2, a notch area 102 is provided at the middle position of the bottom edge of the electronic paper film. Figure 22 The grooved area in the middle, the notch area 102 is also semi-circular.

[0119] In this embodiment, as long as the notch area 102 at the bottom edge of the corresponding electronic paper film is larger than the protruding portion 2 at the top, the electronic paper film can be tightly arranged in the layout. The specific shapes of the notch area 102 and the protruding portion 2 are not limited here. In addition, in the actual product, the protruding portion 2 can be located at the exact center of one edge (top edge or bottom edge) of the electronic paper film, or at any position between the two ends of one edge (top edge or bottom edge) and the exact center, which is not limited here.

[0120] In one optional embodiment of this utility model, such as Figures 29 to 33As shown, the electronic paper film has a rectangular sheet structure or a generally rectangular sheet structure. Each electronic paper film has a protruding portion 2, and the protruding portion 2 is located at one apex of the main body portion 1. At the other three apex positions of the main body portion 1, there are portions of notched areas 102. When multiple electronic paper films are spliced ​​and arranged, four adjacent electronic paper films can fit tightly together. Among the four adjacent electronic paper films, portions of the notched areas 102 at the apex positions of three adjacent electronic paper films are spliced ​​to form a complete notched area 102. The protruding portion 2 on the other electronic paper film is accommodated within the notched area 102, thereby effectively eliminating the generation of unnecessary and invalid areas.

[0121] In one specific embodiment of this utility model, such as Figure 29 As shown, a protruding portion 2 is located at the bottom left corner of the electronic paper film. This protruding portion 2 is a polygon formed by straight lines and arcs. An electrical connection point 3, which is circular in shape, is located on the protruding portion 2. A portion of the electrical connection point 3 is situated within the protruding portion 2. Corresponding to the protruding portion 2, a notch area 102 is located at the top left and right corners of the electronic paper film, and at the bottom right corner of the electronic paper film. Figure 29 The missing corner area 102 is triangular in shape; another part of the electrical connection point 3 is located outside the convex part 2. Therefore, corresponding concave areas need to be set at the three apex positions of the effective display area 1011 and the border area 1012 to avoid the part of the electrical connection point 3 located outside the convex part 2. The concave areas of the effective display area 1011 and the border area 1012 are also triangular in shape.

[0122] In this embodiment, as Figures 30 to 33As shown, the overlapping pattern of the electronic paper film and the set reference rectangle can be divided into four regions. Region 1 is the effective display area 1011 and the border area 1012 covered by the electronic paper film, which is the display function area 101 of the electronic paper film. The shape of this region is a notched rectangle with concave corners (i.e., partially notched area 102). The maximum dimension of this notched rectangle in the width direction (i.e., the X direction) of the electronic paper film is set as X, and the maximum dimension in the height direction (i.e., the Y direction) of the electronic paper film is set as Y. Region 2 is located outside the effective display area 1011 and the border area 1012 of the electronic paper film. It is the protruding part 2 used to set the electrical connection point 3, which is the electrical connection point of the electronic paper film. Following functional area 1, this is described here as area 2, a polygon composed of straight lines and arcs; area 3 includes area 3-1 at the upper left corner, area 3-2 at the upper right corner, and area 3-3 at the lower right corner of the electronic paper film, a total of three concave areas opposite to area 2. Areas 3-1, 3-2, and 3-3 on three adjacent electronic paper films cooperate to accommodate the protruding portion 2 on another adjacent electronic paper film in a translation layout; area 4 is the area corresponding to the electrical connection points 3 outside the protruding portion 2 on the electronic paper film. Area 4 is also used to set a portion of the electrical connection points 3, that is, the electrical connection functional area 2 of the electronic paper film, described here as a triangular area 4. In this embodiment, the electrical connection functional area 1 of area 2 and the electrical connection functional area 2 of area 4 together constitute the electrical connection area of ​​the electronic paper film, and the electrical connection points 3 of the electronic paper film are located within electrical connection functional areas 1 and 2.

[0123] And by Figure 31 and Figure 32 It can be seen that: Region 2 and Region 3 have different shapes; after Region 2 and Region 3 overlap, Region 3 can completely cover Region 2; Electrical connection points 3 are set in the location of Region 2, with some electrical connection points 3 located within Region 2 and others located within Region 4. Region 2 and Region 4 together form the electrical connection functional area where electrical connection points 3 are set. Figure 33 It can be seen that when multiple electronic paper films are arranged in a translational layout, the area of ​​the gap region 102 formed by three adjacent electronic paper films is larger than and can completely cover the convex part 2 of another adjacent electronic paper film. Two adjacent rows and two columns of electronic paper films can still be arranged closely. Although the area of ​​the gap region 102 formed by three adjacent electronic paper films is larger than the outer part 2 of another electronic paper film, the area of ​​this invalid region is very small and will not affect the number of electronic paper films, utilization rate and material cost.

[0124] In some optional embodiments of this utility model, such as Figure 34 and Figure 35As shown, the shape of the notch area 102 on the electronic paper film can also be an inwardly concave arc angle or an outwardly convex arc angle, which can cooperate with the partial notch areas 102 on the other three adjacent electronic paper films to form a complete notch area 102, and can accommodate the outwardly convex part 2. For example, the notch area 102 can also be composed of a straight line, an arc, a polyline composed of a straight line, or an arc. The specific shape of the notch area 102 is not limited here.

[0125] In one optional embodiment of this utility model, such as Figures 36 to 39 As shown, each electronic paper film has one protruding portion 2 and one notch area 102; the protruding portion 2 and the notch area 102 are located at the two opposite corners of the diagonal of the main body 1. When multiple electronic paper films are spliced ​​and arranged, four adjacent electronic paper films are arranged circumferentially along a center point, and the edges of any two adjacent electronic paper films are tightly attached, and the protruding portion 2 on one electronic paper film is accommodated in the notch area 102 on another electronic paper film; or, in the width direction of the electronic paper film, the edges of two adjacent electronic paper films are tightly attached; in the height direction of the electronic paper film, in two adjacent electronic paper films, the protruding portion 2 on one electronic paper film is accommodated in the notch area 102 on another electronic paper film.

[0126] This embodiment illustrates that when the lateral dimension X and longitudinal dimension Y of the electronic paper film are equal, the following can also be used: Figure 38 The electronic paper film shown is arranged in a 90° rotation relative layout (i.e., in... Figure 9 Based on the horizontal arrangement method, each adjacent electronic paper film, both vertically and horizontally, is rotated 90° and then positioned relative to each other before being moved and pressed together. Figure 39 The electronic paper film shown is arranged in a 270° rotation relative layout (i.e., in... Figure 9 Based on the translational arrangement method, each adjacent electronic paper film, both vertically and horizontally, is rotated 270° and then positioned relative to each other before being translated and pressed together, thus achieving a tight arrangement of multiple electronic paper films. A detailed explanation follows.

[0127] like Figure 36 As shown, an electrical connection point 3 is provided at the bottom left corner of the electronic paper film, and a notch area 102 is provided at the top right corner of the electronic paper film; as Figure 37 As shown, an electrical connection point 3 is provided at the bottom right corner of the electronic paper film, and a notch area 102 is provided at the top left corner of the electronic paper film.

[0128] like Figure 38As shown, in the multi-sheet electronic paper film splicing and layout state, four adjacent electronic paper films are arranged circumferentially around a center point, with the edges of any two adjacent electronic paper films tightly attached. Furthermore, the protruding portion 2 on one electronic paper film is accommodated within the notch area 102 on another electronic paper film. This is a 90° rotational relative layout method. Because the protruding portions 2 and notch areas 102 are diagonally arranged on the electronic paper films, adjacent horizontal and vertical rows of electronic paper films can be tightly arranged without any invalid areas. Figure 39 As shown, when multiple electronic paper films are spliced ​​and arranged, the edges of adjacent electronic paper films are tightly fitted in the width direction; in the height direction, the protruding portion 2 of one adjacent electronic paper film is accommodated within the notch area 102 of the other electronic paper film, i.e., the electronic paper films are arranged in a 270° rotation relative arrangement. Because the protruding portion 2 and the notch area 102 are diagonally arranged on the electronic paper films, the electronic paper films in adjacent horizontal and vertical rows can also be tightly arranged without any invalid areas. This utility model... Figure 38 and Figure 39 For illustrative purposes only, in actual product manufacturing, the protruding portion 2 and the notch area 102 on the electronic paper film can be set at any apex position, as long as the protruding portion 2 and the notch area 102 are diagonally opposite each other.

[0129] In some alternative embodiments of this utility model, the area of ​​the notch region 102 is smaller than the area of ​​the protruding part 2. When multiple electronic paper films are in a splicing and layout state, the notch regions 102 on the multiple electronic paper films cooperate (that is, the notch regions 102 on the multiple electronic paper films are spliced ​​together to form a larger accommodating area) to accommodate the protruding part 2 on the adjacent electronic paper film.

[0130] Specifically, the electronic paper film has a rectangular sheet structure or is generally rectangular sheet structure. Each electronic paper film can have one protruding portion 2 and one notch area 102, or multiple notches. For example... Figure 15 As shown, each electronic paper film has two protruding portions 2 and two notched areas 102. The two protruding portions 2 and the two notched areas 102 are located at the four apex corners of the electronic paper film. Specifically, the two notched areas 102 are located at the two opposite top corners of the electronic paper film, while the two protruding portions 2 are located at the two opposite bottom corners of the electronic paper film. Of course, in other embodiments, the two protruding portions 2 may also be located at the two opposite top corners of the electronic paper film, while the two notched areas 102 may be located at the two opposite bottom corners of the electronic paper film.

[0131] In this embodiment, when multiple electronic paper films are in a spliced ​​layout, the edges of adjacent electronic paper films can fit tightly together in the width direction; while in the height direction, in two adjacent electronic paper films, the two protruding portions 2 on one electronic paper film are correspondingly accommodated within the two notched areas 102 on the other electronic paper film, thereby effectively eliminating the generation of unnecessary and invalid areas. Figure 15 As can be seen, the electronic paper film has two protruding parts 2 on its bottom left and bottom right sides, and each of the two protruding parts 2 has an electrical connection point 3. Corresponding to the two protruding parts, there are two notched areas 102 on the top left and top right sides of the electronic paper film, respectively. Figure 15 The missing corner area in the middle, and the shape and size of the missing area 102 are consistent with the shape and size of the convex part 2. In this way, multiple electronic paper films can be closely arranged by using the translation layout method, and there are no invalid areas.

[0132] In the above embodiments of this utility model, the size of the electrical connection point 3 is smaller than the size of the protruding portion 2, and the electrical connection point 3 is located inside the protruding portion 2. In some optional embodiments, the size of the electrical connection point 3 may also be equal to the size of the protruding portion 2, and the electrical connection point 3 overlaps with the protruding portion 2; or only part of the electrical connection point 3 is located inside the protruding portion 2, while another part of the electrical connection point 3 is located outside the protruding portion 2.

[0133] In one specific embodiment of this utility model, such as Figure 24 As shown, there is a protruding portion 2 at the bottom left corner of the electronic paper film. The protruding portion 2 is fan-shaped and has an electrical connection point 3, which is also fan-shaped and occupies the entire protruding portion 2. Corresponding to the protruding portion 2, there is a notch area 102 at the top left corner of the electronic paper film. Figure 24 The missing corner area 102 is also fan-shaped. In the actual product, the electrical connection point 3, the protruding part 2 and the missing area 102 can be any other shape, as long as the electrical connection point 3 fills the entire protruding part 2. The specific shape of the electrical connection point 3, the protruding part 2 and the missing area 102 is not limited here.

[0134] In one specific embodiment of this utility model, such as Figures 25 to 28 As shown, only a portion of the electrical connection points 3 are located inside the protruding portion 2, while the other portion of the electrical connection points 3 are located outside the protruding portion 2. Figure 25As can be seen, the electronic paper film has a convex portion 2 at the middle of its top edge. This convex portion 2 is semi-circular in shape, and an electrical connection point 3 is provided on the convex portion. The electrical connection point 3 is also circular in shape, and only a portion of the electrical connection point 3 is located on the convex portion 2. Corresponding to the convex portion 2, a notch area 102 is provided at the middle of the bottom edge of the electronic paper film. Figure 25 The recessed area in the middle, the notch area 102 is semi-circular in shape. In this embodiment, both the effective display area 1011 and the border area 1012 need to be provided with concave areas to avoid the other part of the electrical connection point 3 located outside the convex part 2.

[0135] Depend on Figures 26 to 28 As can be seen, the overlapping pattern of the electronic paper film and the reference rectangle can be divided into four regions. Region 1 is the effective display area 1011 and the border area 1012 covered by the electronic paper film, which is also the display function area 101 of the electronic paper film. The shape of this region is a rectangle with a groove in the middle of the bottom edge. The maximum dimension of the rectangle with the groove in the width direction (i.e., the X direction) of the electronic paper film is set to X, and the maximum dimension in the height direction (i.e., the Y direction) of the electronic paper film is set to Y. Region 2 is located outside the effective display area 1011 and the border area 1012 of the electronic paper film. It is the protruding part used to set the electrical connection point 3. 2, also known as the electrical connection functional area of ​​the electronic paper film (the area of ​​the ear hole), is a semi-circular area 2; Area 3 is a notch area 102 that is vertically opposite to Area 2. Area 3 is used to accommodate the protruding part 2 of the adjacent electronic paper film in the height direction in the translation layout mode, that is, the notch area 102 of the electronic paper film, which is described here as a rectangular area 3; Area 4 is the area corresponding to the electrical connection point 3 located outside the protruding part 2 of the electronic paper film, which is described here as a semi-circular area 4. The electrical connection functional areas in Area 2 and Area 4 together constitute the electrical connection area of ​​the electronic paper film.

[0136] from Figure 27 and Figure 28 As can be seen, regions 2 and 3 have the same shape, and their edges completely overlap after they overlap. Some electrical connection points 3 are set in the position of region 2, and regions 2 and 4 together form the overall area for setting electrical connection points 3. Some electrical connection points 3 are located in region 2, and other electrical connection points 3 are located in region 4.

[0137] In one optional embodiment of this invention, the protruding portion 2 on the electronic paper film may be located on the same side of the electronic paper film as the integrated circuit 4 on the electronic paper film. Alternatively, the protruding portion 2 on the electronic paper film may be located on the opposite side of the integrated circuit 4 on the electronic paper film.

[0138] In an optional embodiment of this invention, to fully utilize the notch area 102 and enhance its functionality, a functional element can be provided in the notch area 102. This functional element can be, but is not limited to, an illumination element such as an LED light, to enhance the illumination capability of the electronic paper screen and improve the display effect.

[0139] The features and advantages of this electronic paper film are:

[0140] The electronic paper film has a protruding portion 2 for the adaptation of electrical connection points 3, and a corresponding notch area 102 is formed on the electronic paper film. When multiple electronic paper films are spliced ​​and arranged, the notch area 102 on one electronic paper film is used to accommodate the protruding portion 2 on another adjacent electronic paper film, or the notch areas 102 on multiple electronic paper films cooperate to accommodate the protruding portion 2 on another adjacent electronic paper film. This allows multiple electronic paper films to be arranged closely, and the protruding portion 2 on the electronic paper film is accommodated in the layout after the multiple electronic paper films are arranged. There is no need to cut the excess part of the electronic paper film because of the protruding portion 2. This not only eliminates the invalid area left after the layout due to cutting, but also makes the arrangement of multiple electronic paper films more compact and has better overall integrity. It also effectively improves the utilization rate of electronic paper films and solves the problems of waste and increased cost caused by cutting electronic paper films.
