The binding area includes a first edge and a second edge. The first edge is disposed along a first direction, and the second edge is a portion of the edge of the display area that is close to the first edge. Along a direction perpendicular to the first direction, there are multiple margins between the first edge and the second edge. Multiple preset binding terminals are located within the binding area and arranged along the first direction. The maximum size of the preset binding terminals along the first direction is a first size. Among the multiple preset binding terminals, the first size is negatively correlated with the edge distance passing through the center of the preset binding terminal. The maximum size of the preset binding terminals along the direction perpendicular to the first direction is a second size. The second size is positively correlated with the edge distance passing through the center of the preset binding terminal.

[0005] According to an embodiment of the first aspect of the present invention, the first edge includes a straight edge and / or an arc edge disposed along a first direction.

[0006] According to any of the foregoing embodiments of the first aspect of the present invention, the shape of the second edge includes an arc shape. According to any of the foregoing embodiments of the first aspect of the present invention, the edge distance increases from the center of the first edge towards both ends.

[0007] According to any of the foregoing embodiments of the first aspect of the present invention, the first dimension of each of the preset binding terminals gradually decreases from the center of the first edge towards both ends, and the second dimension of each of the preset binding terminals gradually increases from the center of the first edge towards both ends; preferably, the binding area includes a plurality of preset binding terminal combinations, each preset binding terminal combination includes a plurality of preset binding terminals, and the preset binding terminals in each preset binding terminal combination have the same size, and from the center of the first edge towards both ends, the first dimension of the preset binding terminals in each preset binding terminal combination gradually decreases, and the second dimension of the preset binding terminals in each preset binding terminal combination gradually increases.

[0008] According to any of the foregoing embodiments of the first aspect of the present invention, the first side of each of the preset binding terminals near the first edge is located on a virtual line parallel to the first edge. According to any of the foregoing embodiments of the first aspect of the present invention, the shape of the preset binding terminal is rectangular, the rectangle including two opposing first sides and two opposing second sides, the first sides being parallel to the first direction.

[0009] According to any of the foregoing embodiments of the first aspect of the present invention, the shape of the preset binding terminal is a right-angled trapezoid, the right-angled leg of the right-angled trapezoid is parallel to the first direction, the sloping leg of the right-angled trapezoid is located on the side of the right-angled leg facing the second edge, and the two endpoints of the sloping leg are located on a virtual irregular line parallel to the second edge.

[0010] According to any of the foregoing embodiments of the first aspect of the present invention, the preset binding terminal includes a second side adjacent to the second edge, and each of the second sides is located on a virtual irregular line parallel to the second edge.

[0011] According to any of the foregoing embodiments of the first aspect of the present invention, the bonding area of ​​the preset bonding terminal is greater than a preset value, and the preset value is the minimum value at which the preset bonding terminal conduction signal is enabled so that the display panel can be used normally; Preferably, the bonding area of ​​the preset bonding terminal can cover at least ten conductive particles within the anisotropic conductive film; Preferably, the bonding areas of each of the preset bonding terminals are equal.

[0012] An embodiment of the second aspect of this application also provides a display device, including any of the display panels provided in the first aspect of this application. In the display panel provided in this application, a bonding area is located in a non-display area. The bonding area includes a first edge and a second edge. The first edge is disposed along a first direction, and multiple margins exist between the first edge and the second edge along a direction perpendicular to the first direction. The second edge is not parallel to the first edge; specifically, the second edge may be a non-linear irregular shape. The values ​​of the aforementioned margins are different, resulting in a non-uniform space for accommodating preset bonding terminals. Multiple preset bonding terminals are located within the bonding area and arranged along the first direction. The width of the border is typically the value of the margin. Arranging the multiple preset bonding terminals along the first direction ensures that the projections of the bonding terminals along the direction perpendicular to the first direction do not overlap, thereby reducing the margin value. The maximum dimension of the preset bonding terminal along the first direction is the first dimension. Among the multiple preset bonding terminals, the first dimension is negatively correlated with the margin passing through the center of the preset bonding terminal. The maximum dimension of the preset bonding terminal along the direction perpendicular to the first direction is the second dimension, and the second dimension is positively correlated with the margin passing through the center of the preset bonding terminal. That is, the larger the edge distance through the center of the preset binding terminal, the larger the first size and the smaller the second size of the preset binding terminal; the smaller the edge distance through the center of the preset binding terminal, the smaller the first size and the larger the second size of the preset binding terminal. In this way, the space of the binding area can be fully utilized while ensuring the binding area of ​​each preset binding terminal, and the area of ​​the area in the binding area where no preset binding terminal is set can be reduced, thereby achieving the effect of narrow bezel. At the same time, the area of ​​the preset binding terminal is guaranteed, that is, the binding yield is guaranteed, and the narrow bezel and the binding yield are balanced.

Detailed Implementation

[0016] The features and exemplary embodiments of various aspects of this application will now be described in detail. Numerous specific details are set forth in the following detailed description in order to provide a comprehensive understanding of this application. However, it will be apparent to those skilled in the art that this application can be implemented without some of these specific details. The following description of embodiments is merely intended to provide a better understanding of this application by illustrating examples thereof.

[0017] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0018] The inventors discovered that with the development of display technology, the requirements for the appearance of display devices are becoming increasingly stringent. The size of the bezel significantly impacts the appearance of display devices, especially wearable devices such as wristbands and watches. Wearable devices have relatively small display areas, and their aesthetic appeal is crucial for a pleasant wearing experience; therefore, the bezel size greatly influences both the product's appearance and user experience. However, the bezel includes the bonding area, which houses the pre-set bonding terminals for bonding the driving circuitry and / or touch layer within the array substrate to the driving chip. Due to the limitations of the bonding bezel manufacturing process, further reduction in bezel size is difficult, posing a significant technical bottleneck for current design and manufacturing processes. Based on this research, the inventors provide a display panel and display device that can reduce the bezel size, thereby improving the user experience.

[0019] To better understand this application, the following will be combined with... Figures 1 to 14 The display panel and display device according to embodiments of this application will be described in detail.

[0020] Please see Figure 1 and Figure 2This application provides a display panel 1, including a display area AA and a non-display area NA, with the non-display area NA surrounding at least a portion of the display area AA. The display panel 1 includes a bonding area B and a plurality of preset bonding terminals 11. The bonding area B is located in the non-display area NA and includes a first edge L1 and a second edge L2. The first edge L1 is disposed along a first direction x, and the second edge L2 is the portion of the edge of the display area AA closest to the first edge L1. Along a direction perpendicular to the first direction, there are a plurality of edge distances d between the first edge L1 and the second edge L2. The plurality of preset bonding terminals 11 are located within the bonding area B and arranged along the first direction x. The maximum dimension of the preset bonding terminals 11 along the first direction x is a first dimension d1. Among the plurality of preset bonding terminals 11, the first dimension d1 is negatively correlated with the edge distance d passing through the center of the preset bonding terminal 11, and the maximum dimension of the preset bonding terminals 11 along a direction perpendicular to the first direction x is a second dimension d2, which is positively correlated with the edge distance d passing through the center of the preset bonding terminal 11.

[0021] In the display panel 1 provided in this application, the bonding area B is used to set a preset bonding terminal 11 for electrical connection with the flexible circuit board 21 with a driver chip.

[0022] In the display panel 1 provided in this application, the bonding area B is located in the non-display area NA. Specifically, the number of bonding areas B can be one, and it is located on one side edge of the display panel 1, so that only one side edge of the display panel 1 is wider. At the same time, the bonding area B is set to facilitate the connection of the connection terminal in the touch layer 17 and the driver chip.

[0023] In the display panel 1 provided in this application, the bonding area B is located in the non-display area NA. The bonding area B includes a first edge L1 and a second edge L2. The first edge L1 is set along a first direction x. Along a direction perpendicular to the first edge L1, there are multiple edge distances d between the first edge L1 and the second edge L2. The second edge L2 is not parallel to the first edge L1. Specifically, the second edge L2 can be a non-linear irregular shape. The values ​​of the aforementioned edge distances d are different, thus making the space used to accommodate the preset bonding terminals 11 non-uniform. The multiple preset bonding terminals 11 are located in the bonding area B and arranged along the first direction x. The width of the frame is usually the value of the edge distance d. Setting the multiple preset bonding terminals 11 to be arranged along the first direction x can make the projections of the bonding terminals 13 perpendicular to the first direction x non-overlapping, thereby reducing the edge distance d value. The maximum dimension of the preset binding terminal 11 along the first direction x is the first dimension d1. Among the multiple preset binding terminals 11, the first dimension d1 is negatively correlated with the edge distance d passing through the center of the preset binding terminal 11. The maximum dimension of the preset binding terminal 11 along the direction perpendicular to the first direction x is the second dimension d2, and the second dimension d2 is positively correlated with the edge distance d passing through the center of the preset binding terminal 11. That is, the larger the edge distance d passing through the center of the preset binding terminal 11, the larger the first dimension d1 and the smaller the second dimension d2 of the preset binding terminal 11. Conversely, the smaller the edge distance d passing through the center of the preset binding terminal 11, the smaller the first dimension d1 and the larger the second dimension d2 of the preset binding terminal 11. This allows for full utilization of the space in the binding area B while ensuring the binding area of ​​each preset binding terminal 11, reducing the area of ​​the region in the binding area B where no preset binding terminals 11 are set, thereby achieving a narrow bezel effect. At the same time, it ensures the binding area of ​​the preset binding terminals 11, thus ensuring the binding yield, achieving a balance between a narrow bezel and a high binding yield.

[0024] Specifically, setting the first edge L1 along the first direction x means that the first edge L1 has an arrangement direction, extension direction or tangential direction parallel to the first direction x.

[0025] In one feasible implementation, such as Figure 1 , Figure 3 and Figure 4 As shown, the first edge L1 includes a straight edge and / or an arc edge disposed along the first direction x.

[0026] Specifically, when the first edge L1 includes a line segment, it can include a straight edge or an arc edge. When it includes a straight edge, the straight edge extends along the first direction, such as... Figure 3 As shown. Figure 4 As shown, when an arc edge is included, the arc edge includes an axis of symmetry perpendicular to the first direction, and the tangent line at the intersection of the axis of symmetry and the arc edge is perpendicular to the first direction. For example... Figure 1As shown, the first edge L1 may also include a straight edge and two arc edges connecting the two sides of the straight edge, and the straight edge and the two arc edges are arranged along the first direction. This application does not particularly limit the number of side edges included in the first edge L1; when multiple side edges are included, the multiple side edges are arranged along the first direction. For example... Figure 5 As shown, the display panel 1 provided in this application can be a touch display panel 1, including an array substrate 14 and a light-emitting device layer 15, an encapsulation layer 16, a touch layer 17, and a polarizer 18 stacked on one side of the array substrate 14 along a direction away from the array substrate 14. The polarizer 18 covers the display area AA and is partially located in the non-display area NA to ensure light emission effect. The preset bonding terminal 11 is located on the array substrate 14, and the polarizer 18 exposes the preset bonding terminal 11. Along a direction parallel to the light-emitting surface of the display panel 1, the minimum distance between the polarizer 18 and the preset bonding terminal 11 must be greater than a first preset distance to reserve space for bonding and prevent the high temperature and high pressure environment during the bonding process from damaging the performance of the polarizer 18. When the display panel 1 is a touch display panel 1, the bonding area B may include a first bonding area B1 for bonding the touch layer 17 to the flexible circuit board 21 with a driving chip. Alternatively, when the display panel 1 is a touch display panel 1 or a non-touch display panel 1, the bonding area B may include a second bonding area B2 for bonding the driving circuit in the array substrate 14 to the flexible circuit board 21 with a driving chip. The second bonding area B2 may be set on the side of the first bonding area B1 away from the display area AA, so that after bonding with the bonding area B by the flexible circuit board 21 (FPC), it can be folded to the side away from the light-emitting surface of the display panel 1. The preset bonding terminal 11 in the display panel 1 described above may be a bonding terminal 13 for bonding the touch layer 17 to the flexible circuit board 21 with a driving chip. The dividing line between the first bonding area B1 and the second bonding area B2 may be a straight line segment parallel to the first edge L1. The bonding terminals 13 in the second bonding area B2 may have the same shape and bonding area and be uniformly distributed along the first direction x in the second bonding area B2 for easy fabrication.

[0027] In one feasible implementation, such as Figure 2 As shown, the second edge L2 is arc-shaped, and the edge distance d gradually increases from the center of the first edge L1 towards both ends.

[0028] The edge of the display area AA of the display panel 1 may include an arc segment or other irregularly shaped segments; this application does not impose any particular limitation on this. When the edge of the display area AA of the display panel 1 is not parallel to the edge of the non-display area NA on the side away from the display area AA, the area of ​​the bezel portion, i.e., the non-display area NA, will change irregularly and become irregularly shaped. As a result, when the specifications (shape, size) of the preset binding terminal 11 are constant, the area of ​​the non-display area NA will be wasted, and the space of the non-display area NA cannot be fully utilized. In order to achieve the binding effect, the specifications of the binding terminal 13 cannot be excessively compressed, resulting in a large bezel. This application focuses on the example of the edge of the display area AA including an arc segment, i.e., the second edge L2. When the shape of the second edge L2 is arc-shaped, the edge distance d gradually increases from the center of the first edge L1 towards both ends. Therefore, preset binding terminals 11 of different specifications can be set along the first direction x to adapt to the shape of the non-display area NA and make full use of its space.

[0029] In one feasible implementation, such as Figure 2 As shown, the first dimension d1 of each preset binding terminal 11 gradually decreases from the center of the first edge L1 towards both ends, and the second dimension d2 of each preset binding terminal 11 gradually increases from the center of the first edge L1 towards both ends.

[0030] In the above embodiments, since the edge distance d gradually increases from the center of the first edge L1 towards both ends, the preset binding terminals 11 can be configured such that, from the center of the first edge L1 towards both ends, the first dimension d1 of each preset binding terminal 11 gradually decreases, and the second dimension d2 of each preset binding terminal 11 gradually increases. That is, since the edge distance d at the center of the first edge L1 is small, the first dimension d1 of the preset binding terminal 11 at this location cannot be set too large. Therefore, by setting the second dimension d2 to a larger value, the binding area of ​​the preset binding terminal 11 is ensured, thereby ensuring the binding effect. Since the edge distance d at both ends of the first edge L1 is large, the first dimension d1 of the preset binding terminal 11 at this location can be set to a larger value to fully utilize the space perpendicular to the first direction x, while making the second dimension d2 smaller, thereby ensuring that the number of preset binding terminals 11 along the first direction x meets the requirements.

[0031] In the above embodiment, the bonding area B includes a first side and a second side located on both sides of the center of the first edge L1 along the first direction x. The first dimensions d1 of different preset bonding terminals 11 in the first side (or the second side) may all be different and gradually decrease from the center of the first edge L1 towards both ends. The second dimensions d2 of different preset bonding terminals 11 in the first side (or the second side) may all be different and gradually increase from the center of the first edge L1 towards both ends, so as to continuously adjust the size of the preset bonding terminals 11 according to the space of the bonding area B, thereby maximizing the space utilization. The preset bonding terminals 11 on the first side and the second side may be symmetrical along a straight line perpendicular to the first direction x and passing through the center of the first edge L1, so as to facilitate design and manufacturing.

[0032] In one feasible implementation, such as Figure 6 As shown, the binding area B includes multiple preset binding terminal combinations 12, each preset binding terminal combination 12 includes multiple preset binding terminals 11, and the preset binding terminals 11 in each preset binding terminal combination 12 have the same size. From the center of the first edge L1 to both ends, the first size d1 of the preset binding terminals 11 in each preset binding terminal combination 12 gradually decreases, and the second size d2 of the preset binding terminals 11 in each preset binding terminal combination 12 gradually increases.

[0033] In the above embodiments, by dividing the preset binding terminal 11 into multiple preset binding terminal combinations 12, the number of times the specifications of the preset binding terminal 11 are adjusted is reduced while ensuring that the preset binding terminal 11 changes from the center of the first edge L1 to both ends, thereby simplifying the design and manufacturing process.

[0034] In one feasible implementation, the bonding area of ​​the preset bonding terminal 11 is greater than a preset value, which is the minimum value at which the preset bonding terminal conduction signal is enabled so that the display panel can be used normally.

[0035] In the above embodiments, the first size d1 and / or the second size d2 of each preset bonding terminal 11 may be different, but it is necessary to ensure that the bonding area of ​​each preset bonding terminal 11 is greater than the preset value in order to ensure the bonding yield of each preset bonding terminal 11 and improve the manufacturing yield of the display panel 1.

[0036] In one feasible implementation, the bonding area of ​​the preset bonding terminal 11 can cover at least ten conductive particles within the anisotropic conductive film.

[0037] The pre-bonded terminal 11 and the electrical connection end 211 of the flexible circuit board 21 can be electrically connected via an anisotropic conductive film. The anisotropic conductive film includes conductive particles and thermosetting adhesive. By applying pressure to the pre-bonded terminal 11 and the electrical connection end 211 of the flexible circuit board 21 during the bonding process, the thermosetting adhesive is compressed, causing the conductive particles to electrically connect the pre-bonded terminal 11 and the electrical connection end 211 of the flexible circuit board 21. By ensuring that the bonding area of ​​the pre-bonded terminal 11 can cover at least ten conductive particles within the anisotropic conductive film, a good electrical connection effect can be achieved, thereby improving the reliability of the electrical connection.

[0038] In one feasible implementation, the bonding areas of each preset bonding terminal 11 are equal.

[0039] In the above embodiments, by setting the bonding area of ​​each preset bonding terminal 11 to be equal, the resistance value of each preset bonding terminal 11 can be the same, thereby making the conductivity of each preset bonding terminal 11 the same, so as to reduce the difference in the circuits corresponding to different preset bonding terminals 11 and improve the touch stability of the display panel 1.

[0040] In one feasible implementation, such as Figure 7 and Figure 8 As shown, the preset binding terminal 11 includes a second side 111 adjacent to the second edge L2, and each second side 111 is located on a virtual irregular line L3 parallel to the second edge L2.

[0041] In the above implementation, the virtual irregular line L3 being parallel to the second edge L2 means that the center of the circle corresponding to the virtual irregular line L3 coincides with the center of the circle corresponding to the second edge L2, and the radii corresponding to the virtual irregular line L3 and the second edge L2 are different.

[0042] In the above embodiment, the second side 111 is arc-shaped, and the minimum distance between each second side 111 and the second edge L2 is the same. This minimum distance provides space for the bonding of the preset bonding terminal 11 and prevents the high temperature and high pressure environment during the bonding process from damaging the performance of the polarizer 18. Setting each minimum distance to be the same allows each minimum distance to be set to the minimum value under the premise of meeting the bonding requirements, thereby further making full use of the bonding area B space to reduce the frame size and achieve a narrow frame.

[0043] In one feasible implementation, such as Figure 2 As shown, the preset binding terminal 11 is rectangular in shape, and the rectangle includes two opposite first sides 112 and two opposite second sides 113. The first side 112 is parallel to the first direction x.

[0044] In the above embodiments, the rectangular shape of the preset binding terminal 11 reduces design difficulty and facilitates the calculation of the binding area of ​​the preset binding terminal 11. Setting the first side 112 of the rectangle to be parallel to the first direction x makes it easier to control the spacing of the preset binding terminals 11, so as to make full use of the space between adjacent preset binding terminals 11 while ensuring the spacing of the preset binding terminals 11.

[0045] In one feasible implementation, such as Figure 9 and Figure 10 As shown, the shape of the preset binding terminal 11 is a right trapezoid. The right-angled leg 114 of the right trapezoid is parallel to the first direction x. The oblique leg 115 of the right trapezoid is located on the side of the right-angled leg 114 facing the second edge L2, and the two endpoints of the oblique leg 115 are located on the virtual irregular line L3 parallel to the second edge L2.

[0046] In the above embodiment, to simplify the calculation of the bonding area of ​​the preset bonding terminal 11 and the manufacturing process of the preset bonding terminal 11, the shape of the preset bonding terminal 11 can be a right trapezoid. The right-angled waist 114 of the right trapezoid is parallel to the first direction x, which makes it easier to control the spacing of the preset bonding terminals 11, so as to make full use of the space between adjacent preset bonding terminals 11 while ensuring the spacing of the preset bonding terminals 11. The sloping waist 115 of the right trapezoid is located on the side of the right-angled waist 114 facing the second edge L2, and the two endpoints of the sloping waist 115 are located on the virtual irregular line L3 parallel to the second edge L2. This makes full use of the space along the perpendicular direction x and provides space for the bonding of the preset bonding terminals 11, preventing the high temperature and high pressure environment during the bonding process from damaging the performance of the polarizer 18. The above design makes it easy to set the minimum distance between each sloping waist 115 and the second edge L2 to the minimum value under the premise of meeting the bonding requirements, thereby further making full use of the bonding area B space to reduce the frame size and achieve a narrow frame.

[0047] In one feasible implementation, such as Figure 9 As shown, the first side of each preset binding terminal 11 near the first edge L1 is located on a virtual line parallel to the first edge L1.

[0048] In the above embodiments, the space along the first direction x can be fully utilized, and the spacing between the preset binding terminal 11 and the second edge L2 and the first edge L1 can be easily controlled, resulting in a more neat arrangement.

[0049] Here, a virtual line refers to a virtual straight line.

[0050] In another feasible implementation, such as Figure 11 and Figure 12As shown, the shape of the second edge L2 may also include a combination of straight line segments and arc segments, with the arc segments located at both ends of the straight line segments. This application does not impose any particular limitation on this.
