It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0042] This utility model embodiment provides a display module. Figure 1 This is a cross-sectional structural diagram of a display module provided in an embodiment of the present utility model. Figure 1 As shown, the display module includes: a display panel 10, a flexible substrate 20, a touch flexible substrate 30, and an electrostatic shielding layer 40.

[0043] The display panel 10 includes an array substrate 11.

[0044] The flexible substrate 20 is provided with a driving chip 21. The flexible substrate 20 includes a first end and a second end opposite to each other. The first end is electrically connected to the array substrate 11, and the second end is bent on the back side of the array substrate 11.

[0045] The touch flexible substrate 30 includes a third end and a fourth end opposite to each other. The third end is electrically connected to the display panel 10, and the fourth end is bent at the side of the second end of the flexible substrate 20 away from the display panel 10. The orthographic projection of the touch flexible substrate 30 on the array substrate 11 covers at least a portion of the orthographic projection of the flexible substrate 20 on the array substrate 11.

[0046] An electrostatic shielding layer 40 is disposed on the side surface of the touch flexible substrate 30 away from the flexible substrate 20, and the electrostatic shielding layer 40 covers at least a portion of the touch flexible substrate 30.

[0047] Specifically, the display module provided in this embodiment of the present invention is packaged using COF packaging technology. That is, the driver chip 21 is disposed on the flexible substrate 20, and the first end of the flexible substrate 20 is electrically connected to the lower bezel of the array substrate 11 in the display panel 10, thereby enabling the driver chip 21 to transmit signals with the signal traces in the array substrate 11 through the flexible substrate 20. Exemplarily, the flexible substrate 20 can be any one of polyimide (PI), polyethylene terephthalate (PET), polyethylene naphthalate (PEN), and polydimethylsiloxane (PDMS), without limitation. Furthermore, the COF packaging technology allows the second end of the flexible substrate 20 to be bent to the back of the array substrate 11, thereby effectively reducing the width of the lower bezel of the display module and increasing the proportion of the display area. The lower bezel of the display panel 10 is also electrically connected to the third end of the touch flexible substrate 30. A control chip for implementing the touch function of the display panel 10 is disposed on the touch flexible substrate 30. This control chip is electrically connected to the relevant touch traces on the display panel 10 through the touch flexible substrate 30, thereby enabling the control chip to control the display panel 10 to implement the touch function. Furthermore, since the touch flexible substrate 30 also uses a flexible conductive material, its fourth end can also be bent to the back of the array substrate 11, thereby reducing the width of the lower bezel of the display module and increasing the proportion of the display area.

[0048] In actual display processes, the flexible substrate 20 is electrically connected to the array substrate 11 in the display panel 10, and is also electrically connected to a printed circuit board assembly (PCBA) on the side of the flexible substrate 20 away from the array substrate 11, where components are assembled. The flexible substrate 20 has a driver chip 21, i.e., a data signal driver chip (Source IC), and the PCBA has a timer control register IC (Tcon IC). The Tcon IC on the PCBA transmits image signal processing (ISP) signals to the driver chip 21 on the flexible substrate 20, thereby enabling video display on the display panel 10. However, due to insufficient ESD capability in related technologies, the signal transmission link on the flexible substrate 20 of the COF is susceptible to interference, leading to video signal interruption. To address this problem, an electrostatic shielding film layer can be applied to the surface of the signal transmission link to improve the ESD capability of the display module. However, display modules provided by related technologies are limited by cost and mostly use single-layer COF. Single-layer COF is relatively fragile, and its surface cannot withstand an electrostatic shielding film, making it difficult to improve the ESD capability of the display module. Therefore, in the display module provided by this embodiment, the touch flexible substrate 30 is disposed on the side of the flexible substrate 20 away from the display panel 10. The vertical projections of the touch flexible substrate 30 and the flexible substrate 20 overlap to a certain extent, thus the touch flexible substrate 30 can cover the flexible substrate 20 at the overlapping position. The touch flexible substrate 30 is generally formed by stacking multiple substrates and has greater supporting strength. Therefore, setting an electrostatic shielding layer 40 on the surface of the touch flexible substrate 30 covering the flexible substrate 20 is easier to achieve than setting an electrostatic shielding film on the surface of a single-layer COF in related technologies. By covering at least a portion of the flexible substrate 20 with an electrostatic shielding layer 40 on its surface, the touch flexible substrate 30 can provide electrostatic shielding protection for the signal transmission links on the flexible substrate 20, thereby improving the ESD capability of the display module, protecting the signals transmitted between the driver chip 21 and the Tcon IC from interference, and improving the video display effect.

[0049] The display module provided in this embodiment of the present invention has a first end of a flexible substrate with a driver chip electrically connected to an array substrate in a display panel, and a second end bent to the back of the array substrate. A third end of a touch-sensitive flexible substrate is electrically connected to the display panel, and a fourth end is bent to the surface of the second end of the flexible substrate. The orthographic projection of the touch-sensitive flexible substrate onto the array substrate covers at least a portion of the orthographic projection of the flexible substrate onto the array substrate, and an electrostatic shielding layer covers at least a portion of the surface of the touch-sensitive flexible substrate. Compared to related technologies that provide an electrostatic shielding layer on a single-layer COF surface, this method, by having the touch-sensitive flexible substrate cover at least a portion of the flexible substrate in the vertical direction and providing an electrostatic shielding layer on the surface of the touch-sensitive flexible substrate, effectively supports the electrostatic shielding layer. This allows the electrostatic shielding layer to electrostatically shield the signal transmission links on the flexible substrate, thereby effectively improving the ESD capability of the display module and enhancing video display performance.

[0050] Based on the above embodiments, Figure 2 This is a top view structural diagram of the lower bezel portion of a display module according to an embodiment of this utility model. See also: Figure 1 and Figure 2 Optionally, the touch flexible substrate 30 includes at least one first connecting portion 31 and a second connecting portion 32, wherein the width D1 of the first connecting portion 31 is smaller than the width D3 of the second connecting portion 32.

[0051] The first connecting part 31 is connected to the edge of the second connecting part 32, and the first connecting part 31 and the second connecting part 32 are integrally formed and are in the shape of an inverted T.

[0052] The flexible substrate 20 includes at least one, and each flexible substrate 20 is provided with a driving chip 21. At least one flexible substrate 20 is electrically connected at intervals to the edge of the array substrate 11.

[0053] The number of first connecting portions 31 of the touch flexible substrate 30 is the same as the number of flexible substrates 20, and the first connecting portions 31 are arranged in a one-to-one correspondence with the flexible substrates 20.

[0054] Specifically, at least one first connecting portion 31 in the touch flexible substrate 30 is electrically connected to the display panel 10, and is bent at the first connecting portion 31 to bend the second connecting portion 32 to the surface of the flexible substrate 20 away from the array substrate 11. At least one first connecting portion 31 is connected to the edge of the second connecting portion 32, and the width D1 of the first connecting portion 31 is smaller than the width D3 of the second connecting portion 32, such that the first connecting portion 31 and the second connecting portion 32 form an inverted T shape at the connection point, that is, at least one first connecting portion 31 is spaced apart along the edge of the second connecting portion 32. Preferably, at least one first connecting portion 31 is integrally formed with the second connecting portion 32, which can effectively improve the stability of the touch flexible substrate 30 at the bending point. Furthermore, providing at least one narrower first connecting portion 31 at the edge of the second connecting portion 32 can effectively improve the flexibility at the bending point.

[0055] Unlike small-sized display modules, such as mobile phones, which only have one driver chip on the bottom bezel, medium-to-large-sized display modules, such as flat-panel TVs, often have multiple driver chips on the bezel. Therefore, the flexible substrate 20 electrically connected to the array substrate 11 can include at least one, and each flexible substrate 20 has a driver chip 21. The number of first connection portions 31 in the touch flexible substrate 30 is the same as the number of flexible substrates 20, and the first connection portions 31 are arranged in a one-to-one correspondence with the flexible substrates 20, so that at least a portion of each flexible substrate 20 is covered by the first connection portion 31 of the touch flexible substrate 30, and at least a portion of each first connection portion 31 is covered by an electrostatic shielding layer 40. This allows the electrostatic shielding layer 40 to provide electrostatic protection for the signal transmission links connected to the driver chip 21 on each flexible substrate 20.

[0056] Based on the above embodiments, see below. Figure 2 Optionally, the first connecting portion 31 of the touch flexible substrate 30 has a first preset width D1, and the flexible substrate 20 has a second preset width D2; the first preset width D1 is smaller than the second preset width D2.

[0057] The orthographic projection of each first connection portion 31 of the touch flexible substrate 30 onto the array substrate 11 at least covers the orthographic projection of the corresponding driving chip 21 on the flexible substrate 20 onto the array substrate 11.

[0058] The electrostatic shielding layer 40 covers at least the driving chip 21 of the flexible substrate 20 in the width direction.

[0059] Specifically, the first preset width D1 of the first connection portion 31 of the touch flexible substrate 30 can be set to be smaller than the second preset width D2 of the flexible substrate 20. That is, the orthographic projection of the first connection portion 31 on the array substrate 11 only covers a portion of the orthographic projection of the flexible substrate 20 on the array substrate 11 in the width direction, and at least a portion of the surface of the first connection portion 31 is covered by an electrostatic shielding layer 40. This allows the electrostatic shielding layer 40 to provide electrostatic protection for a portion of the flexible substrate 20. Preferably, the coverage width of the orthographic projection of each first connection portion 31 on the array substrate 11 is set to be the same as the width of the orthographic projection of the corresponding driver chip 21 on the array substrate 11. In other words, the electrostatic shielding layer 40 can completely cover the signal transmission link electrically connected to the driver chip 21, which is beneficial to improving the ESD capability of the display module, protecting the ISP signal from interference, and improving the video display effect. Figure 3 This is a top-view structural diagram of the lower bezel of a display module provided by related technologies. (See also...) Figure 3 Compared to related technologies, where the touch flexible substrate 01 only covers part of the driving chip 03 on the flexible substrate 02, resulting in insufficient ESD capability of the display module, the display module provided in this embodiment of the present invention, through the touch flexible substrate 30, at least completely covers the driving chip 21 on the flexible substrate 20, and the electrostatic shielding layer 40 provided on the surface of the touch flexible substrate 30 completely covers the driving chip 21 in the width direction, can effectively improve the ESD capability of the display module.

[0060] Based on the above embodiments, Figure 4 This is a top view structural diagram of the lower bezel of another display module provided in this embodiment of the utility model. See also Figure 4 Optionally, the first connecting portion 31 of the touch flexible substrate 30 has a first preset width D1, and the flexible substrate 20 has a second preset width D2; the first preset width D1 is greater than or equal to the second preset width D2.

[0061] The orthographic projection of each first connection portion 31 of the touch flexible substrate 30 on the array substrate 11 completely covers the orthographic projection of the corresponding flexible substrate 20 on the array substrate 11.

[0062] The electrostatic shielding layer 40 completely covers the flexible substrate 20 in the width direction.

[0063] Specifically, the first preset width D1 of the first connection portion 31 of the touch flexible substrate 30 can be set to be greater than or equal to the second preset width D2 of the flexible substrate 20. That is, the orthographic projection of the first connection portion 31 on the array substrate 11 completely covers the orthographic projection of the flexible substrate 20 on the array substrate 11 in the width direction, and an electrostatic shielding layer 40 is covered at least a portion of the surface of the first connection portion 31. This allows the electrostatic shielding layer 40 to completely protect the flexible substrate 20 from electrostatic discharge. Preferably, the electrostatic shielding layer 40 on the surface of the first connection portion 31 completely covers the first connection portion 31, thereby further enhancing the electrostatic protection of the signal transmission link on the flexible substrate 20, improving the ESD capability of the display module, ensuring that the ISP signal transmitted between the driver chip 21 and TconIC is not interfered with, and preventing video interruption failures.

[0064] Based on the above embodiments, see below. Figure 1 Optionally, the electrostatic shielding layer 40 completely covers the touch flexible substrate 30 in the length direction, and the electrostatic shielding layer 40 covers the end face of the fourth end of the touch flexible substrate 30.

[0065] Specifically, along the length of the flexible touch substrate 30, an electrostatic shielding layer 40 completely covers the flexible touch substrate 30 from its third end to its fourth end, and the electrostatic shielding layer 40 extends to the end face of the fourth end of the flexible touch substrate 30. In this way, the electrostatic shielding layer 40 can completely surround the flexible substrate 20 and the driver chip 21, enabling the electrostatic shielding layer 40 to provide good electrostatic protection for the signal transmission link and protect the transmitted ISP signal from interference.

[0066] Based on the above embodiments, the electrostatic shielding layer 40 may optionally be a mesh-like metal layer.

[0067] Specifically, the mesh-like metal layer completely surrounds the flexible substrate 20 and the driving chip 21, forming a closed conductive structure and grounding it. The surface charge of the mesh-like metal layer is redistributed, generating an induced electric field inside that is opposite to the external electric field, thus canceling the external electric field and achieving electrostatic shielding. The electrostatic shielding layer 40 can be made of materials with high conductivity, good corrosion resistance, high mechanical strength, low cost, and simple manufacturing process. Exemplarily, the electrostatic shielding layer 40 includes copper or gold. However, in this embodiment of the invention, it is not limited to using copper or gold to prepare the electrostatic shielding layer 40; any material with good electrostatic shielding function is acceptable and is not limited here.

[0068] Based on the above embodiments, Figure 5 This is a cross-sectional structural diagram of another display module provided in an embodiment of this utility model. See also... Figure 5 Optionally, the display panel 10 also includes an encapsulation cover 50.

[0069] The encapsulation cover plate 50 is stacked on the surface of the array substrate 11, and the encapsulation cover plate 50 is provided with touch wiring; the third end of the touch flexible substrate 30 is electrically connected to the encapsulation cover plate 50.

[0070] Specifically, an encapsulation cover plate 50 is also provided on the light-emitting side of the display panel 10, and touch control traces are arranged in the encapsulation cover plate 50. The touch flexible substrate 30 is electrically connected to the encapsulation cover plate 50, thereby enabling the display module to realize touch control function. Furthermore, the touch flexible substrate 30 is electrically connected to the encapsulation cover plate 50, and the flexible substrate 20 is electrically connected to the array substrate 11, so that the touch flexible substrate 30 can wrap the flexible substrate 20, thereby making full use of the touch flexible substrate 30. An electrostatic shielding layer 40 is provided on its surface to achieve good electrostatic protection for the signal transmission links on the flexible substrate 20.

[0071] Based on the above embodiments, optionally, the orthographic projection of the touch flexible substrate 30 on the array substrate 11 and the orthographic projection of the encapsulation cover plate 50 on the array substrate 11 have a first overlapping area, and the first overlapping area is provided with conductive adhesive.

[0072] The orthographic projection of the flexible substrate 20 onto the array substrate 11 has a second overlapping region with the array substrate 11, and conductive adhesive is disposed in the second overlapping region.

[0073] Specifically, the flexible touch substrate 30 and the encapsulation cover 50 are electrically connected through a first overlapping region, achieved by coating the first overlapping region with conductive adhesive. Similarly, the flexible substrate 20 and the display panel 10 are electrically connected through a second overlapping region, achieved by coating the second overlapping region with conductive adhesive. For example, the conductive adhesive can be anisotropic conductive film (ACF), but this is not a limitation. A touch sensing layer and an upper polarizer are also stacked on the surface of the encapsulation cover 50 away from the display panel 10 to realize the touch and display functions of the display module.

[0074] This utility model embodiment also provides a display device. Figure 6 This is a schematic diagram of a display device provided in an embodiment of the present invention. See also: Figure 6 The display device can be a medium-to-large-sized laptop computer, a flat-screen TV, etc. The display device includes the display module provided in any embodiment of this utility model; its technical principle and the effects it produces are similar, and will not be described in detail here.

[0075] The specific embodiments described above do not constitute a limitation on the scope of protection of this utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
