[0001] The present invention relates to the field of display technology, and more specifically, to a display module and a display device. Background Art

[0002] At present, display technology has penetrated into every aspect of people's daily life. Accordingly, more and more materials and technologies are used in display screens. As an important component of a display device, a display panel is used to realize the display function of the display device. Today, the mainstream display screens mainly include liquid crystal display panels and organic light-emitting diode (OLED).

[0003] Liquid crystal display panels have the advantages of being thin, light, low power consumption and low radiation, and are widely used in various fields. Organic light-emitting diodes, as a current-type light-emitting device, have been increasingly used in high-performance displays. OLED display panels have many excellent characteristics such as self-luminescence, wide viewing angle, fast response speed, high contrast, wide color gamut, low energy consumption, thin panel, rich colors, flexible display, and wide operating temperature range. Therefore, they are hailed as the next generation of "star" flat panel display technology.

[0004] Whether it is a liquid crystal display panel or an organic light-emitting display panel, it needs to be bound with binding components such as circuit boards. In the related technology, there is a problem of peeling of the binding components, and short circuits, open circuits and other problems are prone to occur in the display panel.

[0005] Therefore, there is an urgent need to provide a display module and a display device that can reduce the risk of peeling of binding components and reduce the risk of short circuit and disconnection of the display panel. Summary of the invention

[0006] In view of this, the present invention provides a display module and a display device, which are used to reduce the risk of peeling of binding components and reduce the risk of short circuit and open circuit of the display panel.

[0050] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless otherwise specifically stated.

[0051] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0052] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0053] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0054] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0055] In view of the problem of peeling of the binding element after binding in the related art, the inventor conducted the following research on the related art, referring to Figure 1 and Figure 2 , Figure 1 is a schematic diagram of a planar structure of a display module in the related art. Figure 2 yes Figure 1 A cross-sectional view taken along the A-A' direction, the binding element 02 is bound to the display panel 01 through the conductive adhesive 07, the display panel 01 has a first binding area 03 and a first non-binding area 011 around the first binding area 03, the first binding area 03 has a first solder pad 05 arranged along the first direction X, the binding element 02 has a second binding area 04 and a second non-binding area 012 around the second binding area 04, the second binding area 04 has a second solder pad 06 arranged along the first direction X, and the first solder pad 05 and the second solder pad 06 are correspondingly bound and electrically connected. The display panel 01 also includes a signal line electrically connected to the first solder pad 05, and the signal line can extend to the display area of ​​the display panel to transmit the signal output by the binding element 02 to the display area to realize the display function of the display area. Of course, the display panel 01 and the binding element 02 also include alignment marks 08 for aligning the binding element 02 and the display panel 01 during binding.

[0056] from Figure 2As can be seen in the figure, the first pad 05 and the second pad 06 are bound by the conductive adhesive 07 to realize the binding of the display panel 01 and the binding element 02. Since the binding process is usually a pressing process, bubbles may be generated in the conductive adhesive 07 between the first pad 05 and the second pad 06 during the pressing process. In addition, in the case where the conductive adhesive 07 is insufficiently filled, the conductive adhesive 07 cannot be fully overflowed after pressing, and the edge where the display panel 01 and the binding element 02 are bound (that is, the edge of the conductive adhesive 07) is prone to generate a larger and longer bubble channel. In this way, water and oxygen will enter between the first pad 05 and the second pad 06 through the bubble channel located at the edge. There are also bubbles between the first pad 05 and the second pad 06, which cannot resist water and oxygen, which may cause the binding to be loose and easily cause the binding element 02 to peel off from the display panel 01; on the other hand, since water and oxygen will enter between the first pad 05 and the second pad 06 through the bubble channel, the first pad 05 and the second pad 06 will be corroded, and then the circuit in the display panel 01 will be corroded, causing short circuit and open circuit.

[0057] In view of this, the present invention provides a display module and a display device to reduce the risk of peeling of a flexible circuit board and reducing the risk of short circuit and open circuit of a display panel. The specific embodiment of the display module will be described in detail below.

[0058] Reference Figure 3 to Figure 9 , Figure 3 is a schematic diagram of a planar structure of a display module provided by the present invention, Figure 4 yes Figure 3 A split diagram of Figure 5 yes Figure 3 A cross-section along the B-B' direction, Figure 6 yes Figure 3 Another split diagram of Figure 7 yes Figure 3 Another cross-sectional view in the middle BB direction, Figure 8 yes Figure 3 Another split diagram of Fig. 9 yes Figure 3 Another cross-sectional view along the B-B' direction. The display module 100 of this embodiment includes a display panel 10 and a binding element 20, wherein the display panel 10 includes a first binding area 1 and a first non-binding area 2 at least partially surrounding the first binding area 1; the first binding area 1 includes a plurality of first pads 3; the binding element 20 includes a second binding area 4 and a second non-binding area 5 at least partially surrounding the second binding area 4; the second binding area 4 includes a plurality of second pads 6, and the second pads 6 are electrically connected to the first pads 3; and at least one blocking structure 7; wherein the blocking structure 7 is located in the first non-binding area 2 and / or the second non-binding area 5.

[0059] Specifically, the display panel 10 of the present invention can be a liquid crystal display panel or an organic self-luminous display panel, which is not specifically limited here. The liquid crystal display panel usually includes a color filter substrate and an array substrate arranged opposite to each other, and a liquid crystal layer between the color filter substrate and the array substrate. A black matrix and a color resist layer are provided on the side of the color filter substrate close to the array substrate. The electric field between the pixel electrode and the common electrode in the display panel can deflect the liquid crystal molecules. After the liquid crystal molecules are deflected, the light generated by the backlight assembly will pass through the display panel. By adjusting the size of the electric field, the liquid crystal molecules can be deflected to different degrees. When the liquid crystal molecules are deflected to different degrees, the light transmittance of the display panel is different, and the amount of light transmitted through the liquid crystal display panel by the backlight assembly is different, thereby realizing the display of the image. The OLED display panel includes an anode and a cathode, and a hole transport layer, an organic light-emitting layer and an electron transport layer arranged between the anode and the cathode. The anode provides hole injection and the cathode provides electron injection. Driven by an external voltage, the holes and electrons injected by the cathode and the anode recombine in the organic light-emitting layer to form electron-hole pairs (i.e., excitons) at a bound energy level. The excitons radiate and de-excite to emit photons, generating visible light.

[0060] Figure 3 It is shown that the display panel 10 includes a first binding area 1 and a first non-binding area 2 at least partially surrounding the first binding area 1, the first binding area 1 includes a plurality of first pads 3, a binding element 20, including a second binding area 4 and a second non-binding area 5 at least partially surrounding the second binding area 4; the second binding area 4 includes a plurality of second pads 6, and the second pads 6 are electrically connected to the first pads 3, that is, the second pads 6 are bound to the first pads 3 to achieve signal transmission. Figure 3 In the figure, only the first pad 3 and the second pad 6 are taken as an example to be schematically explained. Of course, the first pad 3 and the second pad 6 can also be divided into two rows. When the first pad 3 and the second pad 6 are divided into two rows, the number of the first pad 3 and the second pad 6 in each row is halved, which can reduce the width of the first binding area 1 and the second binding area 4 in the first direction X, and increase the spacing between the first pads 3 and the spacing between the second pads 6, which can reduce the risk of crosstalk between adjacent first pads 3 and adjacent second pads 6. The display panel 10 includes a display area AA and a non-display area BB that at least partially surrounds the display area AA. Figure 3 In the figure, only the non-display area BB completely surrounds the display area AA as an example for adaptive description. The non-display area BB includes a left frame BB1, a right frame BB2, an upper frame BB3 and a lower frame BB4. Of course, the display area AA also includes scan lines extending along the first direction X and data lines extending along the second direction Y, which are not shown in the figure. The first binding area 1 is located in the lower frame BB4. Optionally, as Figure 3 As shown, the binding element in the embodiment of the present application includes a flexible circuit board, Figure 3The positional relationship between the blocking structure 7 and the flexible circuit board is illustrated in the example of the binding element being a flexible circuit board. It is understandable that the binding element may also include a driver chip IC, and the blocking structure 7 may also be arranged to match the position of the driver chip IC, which is not limited in the present embodiment.

[0061] Figures 3 to 9 The non-binding area alignment mark 11 is also shown. It can be understood that the alignment mark 11 includes a first alignment mark 12 and a second alignment mark 13. The first alignment mark 12 is located on the display panel 10, and the second alignment mark 13 is located on the binding element 20. When the graphics of the first alignment mark 12 and the second alignment mark 13 match, it indicates that the alignment is accurate. Of course, the graphics of the alignment mark 11 are not specifically limited here. Figures 3 to 9 In the figure, the first alignment mark 12 is a cross and the second alignment mark 13 is four square shapes. Optionally, the first alignment mark 12 and the third alignment mark 13 are also bonded by the conductive adhesive 8.

[0062] Figures 3 to 9 FIG. 4 shows a situation where the first non-binding area 2 partially surrounds the first binding area 1 and the second non-binding area 5 partially surrounds the second binding area 4. In addition, the blocking structure 7 is located on the side of the first binding area 1 or the second binding area 4 close to the left frame BB1 ​​and the side close to the right frame BB2. Figure 4 and Figure 6 The middle blocking structure 7 includes a blocking structure 71 and a blocking structure 73. Figure 8 The middle blocking structure 7 includes a blocking structure 71, a blocking structure 73, a blocking structure 74, and a blocking structure 76. It can be understood that water and oxygen can enter the binding area from the side of the first binding area 1 or the second binding area 4 close to the left frame BB1 ​​or the side close to the right frame BB2. The binding area here refers to the first binding area 1 and the second binding area 4 in the third direction Z, that is, the binding area of ​​the display module 100 as a whole. Therefore, when the blocking structure 7 is set at these three positions, the effect of blocking water and oxygen from entering the binding area is better. Of course, there is no specific limitation here. As long as the blocking structure 7 is set at one of the positions, water and oxygen can be blocked from entering the binding area to varying degrees.

[0063] Figure 4 and Figure 5 It is shown in FIG. 1 that the blocking structure 7 is located in the first non-binding area 2 , that is, the blocking structure 7 is arranged on the display panel 10 . Figure 6 and Figure 7 It is shown that the blocking structure 7 is located in the second non-binding area 5, that is, the blocking structure 7 is arranged on the binding element 20. Figure 8 and Fig. 9It is shown that the blocking structure 7 is located in the first non-binding area 2 and the second non-binding area 5 , that is, the blocking structure 7 is located on both the display panel 10 and the binding element 20 . Figure 5 There is no conductive glue 8 between the middle blocking structure 7 and the binding element 20 , and the conductive glue 8 only stops at the position of the alignment mark 11 . Figure 7 There is a conductive adhesive 8 between the middle barrier structure 7 and the display panel 10, which is only illustrated here for schematic purposes.

[0064] Reference Figure 5 , Figure 7 and Fig. 9 , Figure 5 The middle blocking structure 7 is located in the first non-binding area 2 of the display panel 10, and the height of the blocking structure 7 in the third direction Z is nearly equal to the sum of the heights of the first pad 3 and the second pad 6 in the third direction Z. In the present invention, the third direction Z refers to a direction perpendicular to the plane where the display panel 10 is located; Figure 7 The middle blocking structure 7 is located in the second non-binding area 5 of the binding element 20, and the height of the blocking structure 7 in the third direction Z is nearly equal to the sum of the heights of the first pad 3 and the second pad 6 in the third direction Z; Fig. 9 In the figure, the blocking structure 7 includes a blocking structure 71 located in the first non-binding area 2 of the display panel 10 and a blocking structure 74 located in the second non-binding area 5 of the binding element 20, and the sum of the heights of the blocking structure 71 and the blocking structure 74 in the third direction Z is close to the sum of the heights of the first pad 3 and the second pad 6 in the third direction Z.

[0065] In the above-mentioned display panel, when water and oxygen enter the interior of the binding area from the first non-binding area or the second binding area, they will be blocked by the blocking structure 7 and cannot reach the position where the first pad 3 and the second pad 6 are electrically connected. The water and oxygen will not enter the bubble channel in the conductive adhesive 8. The conductive adhesive 8 can more firmly bond the binding element 20 to the display panel 10 to achieve signal transmission. On the other hand, water and oxygen will not enter the position where the first pad 3 and the second pad 6 are bound, and the water and oxygen will not corrode the first pad 3 and the second pad 6, thereby reducing the risk of short circuit and open circuit in the display panel 10.

[0066] In some optional embodiments, continue to refer to Figure 8 and Fig. 9 , reference Fig.10 and Fig.11 , and reference Figure 12 to Figure 14 , Fig.10 is a schematic diagram of a planar structure of another display module provided by the present invention. Fig.11 yes Fig.10 A cross-sectional view along the M-M' direction, Fig.12 is a schematic diagram of a planar structure of another display module provided by the present invention. Fig.13 yes Fig.12 A split diagram of Fig.14 yes Fig.12 In a cross-sectional view taken along the C-C' direction, the blocking structure 7 includes a first blocking structure 701 located in the first non-binding area 2 and a second blocking structure 702 located in the second non-binding area 5; wherein, in a direction perpendicular to the plane where the display panel 10 is located, at least one first blocking structure 701 and at least one second blocking structure 702 are correspondingly arranged.

[0067] It should be noted that the corresponding settings in the present invention include two situations. One situation is that the first blocking structure 701 and the second blocking structure 702 at least partially overlap in the direction perpendicular to the plane where the display panel 10 is located. The other situation is that along the first direction X, the first blocking structure 701 and the second blocking structure 702 at least partially overlap, and the first direction X refers to the direction in which the first pads are arranged.

[0068] like Fig. 9 As shown, the first blocking structure 701 is located in the first non-binding area 2 of the display panel 10, the first blocking structure 701 is a protruding structure protruding toward one side of the binding element 20, and the first blocking structure 701 is formed on the display panel 10, and the second blocking structure 702 is located in the second non-binding area 5 of the binding element 20, the second blocking structure 702 is a protruding structure protruding toward one side of the display panel 10, and the second blocking structure 702 is formed on the binding element 20. In the direction perpendicular to the plane where the display panel 10 is located, the first blocking structure 701 and the second blocking structure 702 at least partially overlap, which can reduce the space occupied by the blocking structure 7 in the first direction X, that is, reduce the space occupied by the first non-binding area 2 or the second non-binding area 5. Fig. 9 The first blocking structure 701 and the second blocking structure 702 completely overlap, and the first blocking structure 701 and the second blocking structure 702 may partially overlap, which is not specifically limited here. The top surface of the first blocking structure 701 away from the display panel 10 is in contact with the top surface of the second blocking structure 702 away from the binding element 20, thereby forming a barrier to prevent water and oxygen from entering the binding area. Fig. 9 It is shown that the first blocking structure 701 and the second blocking structure 702 can be bonded together by means of the conductive adhesive 8 . Of course, the first blocking structure 701 and the second blocking structure 702 can also be bonded together directly without the conductive adhesive 8 .

[0069] Fig.11 FIG. 4 shows a situation where the first blocking structure 701 overlaps the second blocking structure 702 along the first direction X. The first direction X refers to the direction in which the first pads are arranged. Fig.10 and Fig.11The figure schematically shows the situation in which the first blocking structure 701, the second blocking structure 702, and the first blocking structure 701 are alternately arranged along the first direction X, and there is a gap between the first blocking structure 701 and the second blocking structure 702. Water and oxygen from the side of the first blocking structure 701 away from the first pad 3 need to overcome the blocking structures of multiple first blocking structures 701 and second blocking structures 702 to enter the binding area. Since the path of water and oxygen is a serpentine path, this undoubtedly further increases the path of water and oxygen, which can further play a role in blocking water and oxygen.

[0070] like Fig.14 As shown, the first blocking structure 701 is located in the first non-binding area 2 of the display panel 10, the first blocking structure 701 is a protruding structure protruding toward one side of the binding element 20, the second blocking structure 702 is located in the second non-binding area 5 of the binding element 20, the second blocking structure 702 is a protruding structure protruding toward one side of the display panel 10, the first blocking structure 701 is located on the side of the second blocking structure 702 away from the second pad 6, the side of the first blocking structure 701 close to the second blocking structure 702 is in contact with the side of the second blocking structure 702 close to the first blocking structure 701, Fig.14In the figure, only the conductive adhesive 8 is provided at the position where the side of the first blocking structure 701 close to the second blocking structure 702 and the side of the second blocking structure 702 close to the first blocking structure 701 are bonded, that is, the first blocking structure 701 and the second blocking structure 702 are bonded by the conductive adhesive 8. Of course, the side of the first blocking structure 701 close to the second blocking structure 702 and the side of the second blocking structure 702 close to the first blocking structure 701 can also be bonded directly without the conductive adhesive 8, which is not shown in the figure. By setting the side of the first blocking structure 701 close to the second blocking structure 702 and the side of the second blocking structure 702 close to the first blocking structure 701 to be bonded, on the one hand, the propagation path of water and oxygen is extended, and this structure can also block water and oxygen because the side of the first blocking structure 701 and the side of the second blocking structure 702 are tightly combined, forming a retaining wall to block water and oxygen from entering the binding area. In the third direction Z, the height of the first blocking structure 701 can be less than the sum of the heights of the first pad 3 and the second pad 6 in the third direction Z. In the third direction Z, the height of the second blocking structure 702 can be less than the sum of the heights of the first pad 3 and the second pad 6 in the third direction Z. The height of the portion where the first blocking structure 701 and the second blocking structure 702 fit together in the first direction X in the third direction Z is h2, the height of the portion where the first blocking structure 701 and the second blocking structure 702 do not fit together in the first direction X in the third direction Z is h1, and the height of the portion where the second blocking structure 702 and the first blocking structure 701 do not fit together in the first direction X in the third direction Z is h3. The sum of h1, h2, and h3 is close to the sum of the heights of the first pad 3 and the second pad 6 in the third direction Z, thereby forming a retaining wall that prevents water and oxygen from entering the binding area.

[0071] Optionally, the heights of the first blocking structure 701 and the second blocking structure 702 in the third direction Z are close to the sum of the heights of the first pad 3 and the second pad 6 in the third direction Z, which not only extends the path of water and oxygen, but also the height of the first blocking structure 701 in the third direction Z is close to the sum of the heights of the first pad 3 and the second pad 6 in the third direction Z. Therefore, the first blocking structure 701 is tightly combined with the binding element 20, the height of the second blocking structure 702 in the third direction Z is close to the sum of the heights of the first pad 3 and the second pad 6 in the third direction Z, and the second blocking structure 702 is tightly combined with the display panel 10, completely forming a retaining wall that blocks water and oxygen from entering the binding area, thereby better blocking water and oxygen from entering the binding area.

[0072] In some optional embodiments, continue Fig.10 , Fig.11 , and continue to refer to Fig.12 , Fig.13 and Fig.14In the corresponding first blocking structure 701 and the second blocking structure 702, along the first direction X, the first blocking structure 701 and the second blocking structure 702 at least partially overlap, and the first direction X is the direction in which the first pads are arranged.

[0073] As described above, along the first direction X, the first blocking structure 701 and the second blocking structure 702 at least partially overlap, which can extend the propagation path of water and oxygen, thereby further improving the effect of blocking water and oxygen.

[0074] In some optional embodiments, referring to Fig.15 , Fig.16 and Fig.17 , Fig.15 is a schematic diagram of a planar structure of another display module provided by the present invention. Fig.16 yes Fig.15 The split diagram, Fig.17 yes Fig.15 In a cross-sectional view taken along the D-D′ direction, in the first blocking structure 701 and the second blocking structure 702 that are arranged correspondingly, the first blocking structure 701 and the second blocking structure 702 are engaged with each other.

[0075] Fig.15 Only the blocking structures 7 located on both sides of the first pad 3 in the first direction X are shown. Of course, a blocking structure 7 may also be provided on the side of the first pad 3 away from the display area AA in the second direction Y, which is not shown in the figure.

[0076] from Fig.16 It can be seen that the orthographic projection pattern of the second blocking structure 702 on the plane where the display panel 10 is located is complementary to the orthographic projection pattern of the first blocking structure 701 on the plane where the display panel 10 is located, that is, the second blocking structure 702 is filled between the first blocking structures 701. This structure can block water and oxygen from entering the binding area. Moreover, since the second blocking structure 702 is filled between the first blocking structure 701, the contact surface between the first blocking structure 701 and the second blocking structure 702 is a side surface, which makes the binding force between the first blocking structure 701 and the second blocking structure 702 more stable. On the other hand, it also improves the binding force between the binding element 20 and the display panel 10, thereby improving the binding stability.

[0077] Fig.17 In the figure, the conductive glue 8 is only stopped at the position of the alignment mark 11, and there is no conductive glue 8 between the first blocking structure 701 and the second blocking structure 702. Since the bonding force between the first blocking structure 701 and the second blocking structure 702 is relatively stable, the bonding force between the binding element 20 and the display panel 10 can be improved without the conductive glue 8.

[0078] In the third direction Z, the height of the first blocking structure 701 can be less than the sum of the heights of the first pad 3 and the second pad 6 in the third direction Z. In the third direction Z, the height of the second blocking structure 702 can be less than the sum of the heights of the first pad 3 and the second pad 6 in the third direction Z. The height of the portion where the first blocking structure 701 and the second blocking structure 702 fit together in the first direction X in the third direction Z is h2. The height of the portion where the first blocking structure 701 and the second blocking structure 702 do not fit together in the first direction X in the third direction Z is h1. The height of the portion where the second blocking structure 702 and the first blocking structure 701 do not fit together in the first direction X in the third direction Z is h3. The sum of h1, h2, and h3 is close to the sum of the heights of the first pad 3 and the second pad 6 in the third direction Z, thereby better preventing water and oxygen from entering the binding area. Of course Fig.17 It is shown in the figure that the height of the first blocking structure 701 can be close to the sum of the heights of the first pad 3 and the second pad 6 in the third direction Z, and the height of the second blocking structure 702 is close to the sum of the heights of the first pad 3 and the second pad 6 in the third direction Z. At this time, the first blocking structure 701 is combined with the binding element 20, and the second blocking structure 702 is combined with the display panel 10. This can further improve the ability to prevent water and oxygen from entering the binding area. In addition, it can also further increase the contact area between the sides of the first blocking structure and the second blocking structure 702, increase the bonding force between the first blocking structure 701 and the second blocking structure 702, and improve the stability of the binding element 20.

[0079] It should be noted that Fig.15 and Fig.16 The orthographic projection patterns of the first blocking structure 701 and the second blocking structure 702 on the plane where the display panel 10 is located are shown as a maze pattern. This maze pattern can further extend the path of water and oxygen inside the blocking structure 7. Of course, it can also be other shapes, such as a square shape, a circle shape, etc., which are not specifically limited here. Of course, the blocking structure 7 with a maze pattern is more conducive to the capture and positioning of the high-speed camera, so it can also be used as a positioning mark, thereby improving the binding accuracy and binding efficiency.

[0080] In some optional embodiments, continue to refer to Fig.17 In the corresponding first blocking structure 701 and the second blocking structure 702, along the direction perpendicular to the plane where the display panel 10 is located, the difference between the height of the first blocking structure 701 or the height of the second blocking structure 702 and the sum of the heights of the first pad 3 and the second pad 6 is within a preset range.

[0081] The difference in the present invention is within a preset range, which refers to the consideration of the error in process accuracy and the thickness of the conductive adhesive 8 between the first pad 3 and the second pad 6 .

[0082] Fig.17 In the example, only the case where there is no conductive glue between the first blocking structure 701 and the binding element 20, and there is no conductive glue between the second blocking structure 702 and the display panel 10 is taken. At this time, the difference between the height of the first blocking structure 701 or the height of the second blocking structure 702 and the sum of the heights of the first pad 3 and the second pad 6 is within a preset range, and the preset range includes the error in process precision and the thickness of the conductive glue 8 between the first pad 3 and the second pad 6 in the third direction Z.

[0083] Of course, there can also be conductive glue between the first blocking structure 701 and the binding element 20. At this time, the sum of the height of the first blocking structure 701 and the thickness of the conductive glue between the first blocking structure 701 and the binding element 20 is close to the sum of the height of the first pad 3, the height of the second pad 6, and the thickness of the conductive glue 8 between the first pad 3 and the second pad 5. In addition to considering the error in process precision, the preset range at this time also includes the difference between the thickness of the conductive glue between the first blocking structure 701 and the binding element 20 and the thickness of the conductive glue 8 between the first pad 3 and the second pad 5.

[0084] Similarly, there may be conductive glue between the second blocking structure 702 and the display panel 10. At this time, the sum of the height of the second blocking structure 702 and the thickness of the conductive glue between the second blocking structure 701 and the display panel 10 is close to the sum of the height of the first pad 3, the height of the second pad 6, and the thickness of the conductive glue 8 between the first pad 3 and the second pad 5. In addition to considering the error in process accuracy, the preset range at this time also includes the difference between the thickness of the conductive glue between the second blocking structure 702 and the display panel 10 and the thickness of the conductive glue 8 between the first pad 3 and the second pad 5.

[0085] Fig.17 In the figure, the first blocking structure 701 and the second blocking structure 702 are complementary structures. In the direction perpendicular to the plane where the display panel 10 is located, the heights of the first blocking structure 701 and the second blocking structure 702 are respectively approximately equal to the sum of the heights of the first pad 3 and the second pad 6.

[0086] On the one hand, in the corresponding first blocking structure 701 and the second blocking structure 702, along the direction perpendicular to the plane where the display panel 10 is located, the difference between the height of the first blocking structure 701 or the height of the second blocking structure 702 and the sum of the heights of the first pad 3 and the second pad 6 is within a preset range, which can effectively prevent water and oxygen from entering the binding area from the gap between the first blocking structure 701 and / or the second blocking structure 702. On the other hand, if the height of the first blocking structure 701 or the second blocking structure 702 is too different from the sum of the heights of the first pad 3 and the second pad 6, for example, much greater than the sum of the heights of the first pad 3 and the second pad 6, then the first blocking structure 701 or the second blocking structure 702 will support the edge of the binding element 20, causing the edge of the binding element 20 to bend toward the side away from the display panel 10, thereby causing a peeling force to the first pad 3 and the second pad 6 in the binding area, making the binding between the first pad 3 and the second pad 6 unstable. Therefore, in the direction perpendicular to the plane where the display panel 10 is located, the difference between the height of the first blocking structure 701 or the height of the second blocking structure 702 and the sum of the heights of the first pad 3 and the second pad 6 is within a preset range, which can ensure that the first pad 3 and the second pad 6 will not be subjected to a peeling force, and can also ensure the blocking effect of preventing water and oxygen from entering the binding area.

[0087] In some optional embodiments, continue to refer to Fig. 9 In the corresponding first blocking structure 701 and the second blocking structure 702, the first blocking structure 701 and the second blocking structure 702 at least partially overlap in a direction perpendicular to the plane where the display panel 100 is located. As mentioned above, the space occupied by the blocking structure 7 in the first direction X can be reduced, that is, the space occupied by the first non-binding area 2 or the second non-binding area 5 can be reduced.

[0088] In some optional embodiments, continue to refer to Fig. 9 In the correspondingly arranged first blocking structure 701 and second blocking structure 702 , the first blocking structure 701 and the second blocking structure 702 are in contact with each other.

[0089] Specifically, in the present invention, the bonding between the first blocking structure 701 and the second blocking structure 702 includes two situations. One is that the surface of the first blocking structure 701 close to the second blocking structure 702 is directly contacted and bonded with the surface of the second blocking structure 702 close to the first blocking structure 701. The other situation is that the surface of the first blocking structure 701 close to the binding element 20 and the surface of the second blocking structure 702 close to the display panel 10 are bonded by conductive adhesive.

[0090] Fig. 9In the figure, the surface of the first blocking structure 701 close to the binding element 20 and the surface of the second blocking structure 702 close to the display panel 10 are bonded by conductive adhesive, so that the first blocking structure and the second blocking structure 702 are more firmly bonded. Of course, the surface of the first blocking structure 701 close to the binding element 20 and the surface of the second blocking structure 702 close to the display panel 10 can also be directly contacted and bonded, that is, there is no conductive adhesive between the first blocking structure 701 and the second blocking structure 702, which is not shown in the figure here.

[0091] After the first blocking structure 701 and the second blocking structure 702 are bonded together, since the first blocking structure 701 is set on the display panel 10 and the second blocking structure 702 is set on the binding element 20, and the first blocking structure 701 and the second blocking structure 702 are bonded together, the path for water and oxygen to enter is completely isolated, further preventing the binding element 20 from peeling off, and further reducing the risk of short circuit or open circuit of the display panel 10 due to water and oxygen corrosion.

[0092] In some optional embodiments, continue to refer to Fig. 9 In the corresponding first blocking structure 701 and the second blocking structure 702, along the direction perpendicular to the plane where the display panel 10 is located, the difference between the sum of the heights of the first blocking structure 701 and the second blocking structure 702 and the sum of the heights of the first pad 3 and the second pad 6 is within a preset range.

[0093] Fig. 9 In the embodiment, there is a conductive glue 8 between the first blocking structure 701 and the second blocking structure 702. At this time, along the direction perpendicular to the plane where the display panel 10 is located, the height of the first blocking structure 701, the height of the second blocking structure 702, and the sum of the thickness of the conductive glue 8 between the first blocking structure 701 and the second blocking structure 702 are close to the height of the first pad 3, the height of the second pad 6, and the sum of the thickness of the conductive glue between the first pad 3 and the second pad 6. At this time, the preset range includes the difference between the thickness of the conductive glue 8 between the first blocking structure 701 and the second blocking structure 702 and the thickness of the conductive glue 8 between the first pad 3 and the second pad 6. Of course, the preset range also includes errors in manufacturing accuracy.

[0094] Optionally, when there is no conductive adhesive 8 between the first blocking structure 701 and the second blocking structure 702 (see Fig.32 ), at this time, along the direction perpendicular to the plane where the display panel 10 is located, the sum of the height of the first blocking structure 701 and the height of the second blocking structure 702 is close to the sum of the height of the first pad 3, the height of the second pad 6, and the thickness of the conductive adhesive between the first pad 3 and the second pad 6. The preset range at this time needs to include the thickness of the conductive adhesive 8 between the first pad 3 and the second pad 6, as well as the error in manufacturing accuracy.

[0095] On the one hand, in the corresponding first blocking structure 701 and the second blocking structure 702, along the direction perpendicular to the plane where the display panel 10 is located, the difference between the sum of the heights of the first blocking structure 701 and the second blocking structure 702 and the sum of the heights of the first pad 3 and the second pad 6 is within a preset range, which can effectively prevent water and oxygen from entering the binding area from the gap between the first blocking structure 701 and the second blocking structure 702. On the other hand, if the sum of the heights of the first blocking structure 701 and the second blocking structure 702 differs too much from the sum of the heights of the first pad 3 and the second pad 6, for example, is much greater than the sum of the heights of the first pad 3 and the second pad 6, then the first blocking structure 701 and the second blocking structure 702 will support the edge of the binding element 20, causing the edge of the binding element 20 to bend toward the side away from the display panel 10, thereby causing a peeling force to the first pad 3 and the second pad 6 in the binding area, making the binding between the first pad 3 and the second pad 6 unstable; along the direction perpendicular to the plane where the display panel 10 is located, the difference between the height of the first blocking structure 701 and the sum of the heights of the second blocking structure 702 and the sum of the heights of the first pad 3 and the second pad 6 is within a preset range, which can ensure that the first pad 3 and the second pad 6 will not be subjected to a peeling force, and can also ensure the blocking effect of preventing water and oxygen from entering the binding area.

[0096] In some optional embodiments, continue to refer to Fig.15 , Fig.16 , and reference Fig.18 , Fig.19 , Fig. 20 , Fig.21 , Fig. 22 and Fig.23 , Fig.18 is a schematic diagram of a planar structure of another display module provided by the present invention. Fig.19 yes Fig.18 A split diagram of Fig. 20 is a schematic diagram of a planar structure of another display module provided by the present invention. Fig.21 yes Fig. 20 A split diagram of Fig. 22 is a schematic diagram of a planar structure of another display module provided by the present invention. Fig.23 yes Fig. 22 The orthographic projection of the blocking structure 7 on the plane where the display panel 10 is located includes a closed figure.

[0097] In this embodiment, the orthographic projection pattern of the blocking structure 7 on the plane where the display panel 10 is located is a closed figure, and the closed figure includes but is not limited to maze-shaped, square-shaped, and U-shaped patterns.

[0098] Fig.18 and Fig.19, the orthographic projection of the blocking structure 7 on the plane where the display panel 10 is located is shown as a maze-like pattern, wherein the shapes of the first blocking structure 701 and the second blocking structure 702 are exactly the same. At this time, in the direction perpendicular to the plane where the display panel 10 is located, the first blocking structure 701 and the second blocking structure can fit together.

[0099] Fig. 20 and Fig.21 In the figure, the orthographic projection of the blocking structure 7 on the plane where the display panel 10 is located is in the shape of a square. Fig.21 In the embodiment, the shapes of the first blocking structure 701 and the second blocking structure 702 are exactly the same. In this case, the first blocking structure 701 and the second blocking structure can be attached to each other in a direction perpendicular to the plane where the display panel 10 is located. Of course, the shapes of the first blocking structure 701 and the second blocking structure 702 can also be complementary, such as Fig. 22 and Fig.23 In the figure, the orthographic projection of the blocking structure 7 on the plane where the display panel 10 is located is in the shape of a square. Fig.23 In the figure, the shapes of the first blocking structure 701 and the second blocking structure 702 are complementary, and the orthographic projection of the second blocking structure 702 on the plane where the display panel 10 is located fills the hollowed-out part of the first blocking structure 701. At this time, in the direction perpendicular to the plane where the display panel 10 is located, the height of the first blocking structure 701 is close to the sum of the heights of the first pad 3 and the second pad 6, and the height of the second blocking structure 702 can also be close to the sum of the heights of the first pad 3 and the second pad 6, which is not shown in the figure.

[0100] In this embodiment, the orthographic projection pattern of the blocking structure 7 on the plane where the display panel 10 is located is a closed figure, and this closed figure can further extend the path of water and oxygen inside the blocking structure 7.

[0101] In addition, the orthographic projection pattern of the blocking structure 7 in the present invention on the plane where the display panel 10 is located is a closed figure, which can also improve the accuracy of alignment. It can be understood that when binding the binding element 20 to the display panel 10, it is necessary to use a high-speed camera to capture and align the binding element 20 and the display panel 10 respectively, and then press the binding element 20 with a pressing head after determining the position, so that the binding element 20 and the display panel 10 are bonded by the conductive adhesive 8 to improve the accuracy of binding and complete signal transmission. The blocking structure 7 in the present invention can also be used as an alignment mark 11, because the closed figure is more conducive to the capture and positioning of the high-speed camera, thereby improving the binding accuracy and binding efficiency.

[0102] In some optional embodiments, referring to Fig.24 and Fig.25 , Fig.24 is a schematic diagram of a planar structure of another display module provided by the present invention. Fig.25 yes Fig.24A disassembled diagram of the present invention shows that the blocking structure 7 includes a plurality of sub-blocking structures 70 , and there is a gap between adjacent sub-blocking structures 70 .

[0103] Fig.24 and Fig.25 The number of neutron blocking structures 70 is only for schematic illustration and can be determined based on the empty space of the first non-binding area 2 and the second non-binding area 5. Of course, the more the number of neutron blocking structures 70, the more conducive it is to blocking water and oxygen from entering the binding area.

[0104] It should be noted that the lengths of the sub-blocking structures 70 may be equal or unequal. Fig.24 and Fig.25 Only the case where the lengths of the sub-blocking structures 70 are unequal is shown. Of course, the lengths of the sub-blocking structures 70 may also be equal, which is not specifically limited here.

[0105] Fig.24 As can be seen, optionally, the sub-blocking structure 70 is in the shape of a vertical bar. Water and oxygen need to pass through multiple sub-blocking structures 70 in sequence to enter the binding area. The provision of multiple sub-blocking structures 70 significantly increases the difficulty of water and oxygen entering the binding area, which is more conducive to blocking water and oxygen. In addition, there is a gap between adjacent sub-blocking structures 70, which is equivalent to forming a buffer zone, which will block water and oxygen in the adjacent gaps, further improving the effect of blocking water and oxygen.

[0106] Optionally, the first blocking structure 701 on the display panel 10 may be attached to the top surface of the second blocking structure 702 on the binding element 20, or Figure 12 to Figure 14 In the embodiment, the first blocking structure 701 on the display panel 10 can be laterally engaged with the second blocking structure 702 on the binding element 20 , and the engagement can further enhance the bonding force between the binding element 20 and the display panel 10 , thereby preventing the binding element 20 from peeling off from the display panel 10 .

[0107] In some optional embodiments, the orthographic projection of the blocking structure 7 on the plane where the display panel 10 is located may include both a closed figure and one or more sub-blocking structures 70, which is not shown in the figure. When the orthographic projection of the blocking structure 7 on the plane where the display panel 10 is located includes both a closed figure and one or more sub-blocking structures 70, this structure can further block water and oxygen from entering the binding area, because water and oxygen are first blocked once by the sub-blocking structure 70 and then blocked once by the closed-figure blocking structure 7, which increases the difficulty of water and oxygen entering the binding area.

[0108] In some optional embodiments, continue to refer to Fig.24 and Fig.25 , and reference Fig.26 and Fig. 27 , Fig.26 is a schematic diagram of a planar structure of another display module of the present invention, Fig. 27 yes Fig.26 A split diagram, the first pad 3 and / or the second pad 6 are arranged along the first direction X and extend along the second direction Y; the first direction X intersects the second direction Y;

[0109] The extension direction of the sub-blocking structure 70 is the same as the extension direction of the first pad 3 and / or the second pad 6 .

[0110] It can be understood that the extension direction of the sub-blocking structure 70 is the same as the extension direction of the first pad 3 and the second pad 6. Fig.24 and Fig.25 In the embodiment, the first pad 3 and the second pad 6 extend along the column direction V, and the sub-blocking structure 70 also extends along the column direction V, which can play a good blocking role. Fig.26 and Fig. 27 In the figure, the first pad 3 and the second pad 6 are arranged in an eight-shaped arrangement, and the angle between the first pad 3 and the column direction V is greater than 0° and less than 90°. At this time, the extension direction of the sub-blocking structure 70 changes along with the angle change of the first pad 3 and the second pad 6, and matches the arrangement shape of the first pad 3 and the second pad 6, and can play a good blocking role.

[0111] In some optional embodiments, continue to refer to Figures 3 to 27 , and reference Fig.28 and Fig.29 , Fig.28 is a schematic diagram of a planar structure of another display module provided by the present invention. Fig.28 is a schematic diagram of a planar structure of another display module provided by the present invention. Fig.29 is a schematic diagram of a planar structure of another display module provided by the present invention, wherein the display module 100 further includes an alignment mark 11 located in the first non-binding area 2 and the second non-binding area 5;

[0112] When the blocking structure 7 includes a first blocking structure 701 located in the first non-binding area 2; the first blocking structure 701 is located on a side of the alignment mark 11 away from the first pad 3, and / or the first blocking structure 701 is located between the alignment mark 11 and the first pad 3;

[0113] When the blocking structure 7 includes the second blocking structure 702 located in the second non-binding area 5 , the second blocking structure 702 is located on a side of the alignment mark 11 away from the second pad 6 , and / or the second blocking structure 702 is located between the alignment mark 11 and the second pad 6 .

[0114] It can be understood that the alignment mark 11 includes a first alignment mark 12 and a second alignment mark 13. The first alignment mark 12 is located on the display panel 10, and the second alignment mark 13 is located on the binding element 20. When the graphics of the first alignment mark 12 and the second alignment mark 13 match, it indicates that the alignment is accurate. Of course, the graphics of the alignment mark 11 are not specifically limited here. Figures 3 to 29 In the figure, the first alignment mark 12 is a cross and the second alignment mark 13 is four square shapes as an example for schematic description.

[0115] Figures 3 to 27 As shown in the figure, the blocking structure 7 is located on the side of the alignment mark 11 away from the first pad 3. Of course, the blocking structure 7 here can be the first blocking structure 701 located in the first non-binding area 2, or the second blocking structure 702 located in the second non-binding area 5, and no specific limitation is made here. Fig.28 The middle blocking structure 7 is located on the side of the alignment mark 11 close to the first pad 3. Fig.29 The middle blocking structure 7 is located on a side of the alignment mark 11 close to the first pad 3 and on a side of the alignment mark 11 far from the first pad 3 .

[0116] Figure 28 to Figure 29 In the example, the blocking structure 7 is a vertical bar blocking structure 7, which can also be a closed shape, and is not specifically limited here. Of course, the blocking structure 7 can also include a plurality of sub-blocking structures 70, with intervals between adjacent sub-blocking structures 70, and the number of sub-blocking structures 70 can be determined according to the space between the first non-blocking area and the second non-blocking area.

[0117] It can be understood that when water and oxygen enter the binding area from one side of the alignment mark 11, there is an accommodating space between the alignment mark 11 and the blocking structure 7, and the water and oxygen will be blocked in the space between the alignment mark 11 and the blocking structure 7. By utilizing the existing alignment mark 11 in the display module 100, combined with the blocking structure 7 added in the present invention, it is possible to further prevent water and oxygen from entering the binding area, thereby ensuring that the first solder pad 3 and the second solder pad 6 will not peel off, and also ensuring the blocking effect of preventing water and oxygen from entering the binding area.

[0118] In some optional embodiments, continue to refer to Figure 3 , the first pads 3 and / or the second pads 6 are arranged along the first direction X and extend along the second direction Y; the first direction X intersects the second direction Y;

[0119] Along the second direction Y, the length of the blocking structure 7 is greater than the length of the first pad 3 and / or the second pad 6 .

[0120] The first pad 3 and the second pad 6 are arranged along the first direction X. Of course, along the first direction X, the blocking structure 7 is located on both sides of the first pad 3 and the second pad 6. Along the second direction Y, the length of the blocking structure 7 is greater than the length of the first pad 3 and / or the second pad 6. It can be understood that the greater the length of the blocking structure 7 in the second direction Y, the more it can block water and oxygen from entering the binding area. In this embodiment, the length of the blocking structure 7 in the second direction Y is greater than the length of the first pad 3 or the second pad 6, and can completely block water and oxygen from entering the binding area in the second direction Y.

[0121] In some optional embodiments, referring to Figure 30 to Figure 32 , Fig.30 yes Figure 3 Another cross-sectional view in the B-B' direction, Fig.31 yes Figure 3 Another cross-sectional view in the B-B' direction, Fig.32 yes Figure 3 Another cross-sectional view along the BB' direction. The blocking structure 7 includes a first blocking structure 701 located in the first non-binding area 2; the material of the first blocking structure 701 is the same as that of the first pad 3;

[0122] And / or, the blocking structure 7 includes a second blocking structure 702 located in the second non-binding region 5 ; the material of the second blocking structure 702 is the same as that of the second pad 6 .

[0123] Fig.30 As shown in the figure, the blocking structure 7 includes a first blocking structure 701 located in the first non-binding area 2. The material of the first blocking structure 701 is the same as the material of the first pad 3. When manufacturing the first blocking structure 701, it can be manufactured simultaneously with the first pad 3. There is no need to add a manufacturing process to manufacture the first blocking structure 701, which can simplify the manufacturing process. Fig.31 The blocking structure 7 shown in the figure includes a second blocking structure 702 located in the second non-binding area 5. The material of the second blocking structure 702 is the same as the material of the second pad 6. When the second blocking structure 702 is manufactured, it can be manufactured simultaneously with the second pad 6. There is no need to add a manufacturing process to manufacture the second blocking structure 702, which can simplify the manufacturing process. Fig.32 FIG. 4 shows that the blocking structure 7 includes a first blocking structure 701 located in the first non-binding area 2 and a second blocking structure 702 located in the second non-binding area 5.
