[0006] Optionally, the polarizing layer has a second extension that protrudes from the end face of the color filter substrate. The first extension, the end face of the color filter substrate, and the second extension together define a first groove that connects the polarizing layer, the color filter substrate, and the array substrate.

[0007] Optionally, the end face of the first extension forms a second groove with the outer wall of the frame near the array substrate. The second groove communicates with the first groove, and a portion of the conductive adhesive is disposed in the second groove to connect the array substrate and the frame.

[0008] Optionally, the first extension portion defines an adhesive overflow groove between the side facing away from the color filter substrate and the frame, the second groove communicates with the adhesive overflow groove, and a portion of the conductive adhesive is disposed in the adhesive overflow groove to connect the array substrate and the frame.

[0009] Optionally, the frame includes a glue frame and a back plate, the glue frame is embedded in the back plate, the end face of the glue frame near the first extension is a slope, and the slope and the side of the first extension away from the color filter substrate define the glue overflow groove.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0020] This application provides a display device; please refer to [link / reference]. Figure 1 , Figure 2 and Figure 3 The display device includes a frame 1, a display panel 2, and conductive adhesive 3.

[0021] Furthermore, the frame 1 can be understood as a support structure for supporting the display panel 2. Specifically, it can be a middle frame, a border, or a support bracket in the display module. Its main function is to provide an installation base for the display panel 2 and to provide limiting support for the edge area of ​​the display panel 2.

[0022] For example, the display panel 2 is located on the frame 1, and the display panel 2 includes an array substrate 21, a color filter substrate 22 and a polarizing layer 23.

[0023] For example, the array substrate 21 can be a TFT glass substrate on which a thin-film transistor array, electrode wiring and pixel driving structure are formed; the color filter substrate 22 is located on the side of the array substrate 21 away from the frame 1; the color filter substrate 22 can be understood as a glass substrate with a color filter layer, a black matrix layer and other structures formed thereon, used to cooperate with the array substrate 21 to form a liquid crystal display unit; the polarizing layer 23 is located on the side of the color filter substrate 22 away from the array substrate 21; the polarizing layer 23 can be a polarizer or a film structure with polarization function, used to adjust the polarization direction of light to meet display requirements.

[0024] For example, the array substrate 21 has a first extension 211 that protrudes from the end face of the color filter substrate 22.

[0025] Specifically, the first extension 211 can be understood as a protruding area extending outward from the edge of the array substrate 21. This area can form a height difference with the color filter substrate 22 in a direction perpendicular to the thickness direction, and extends beyond the boundary of the color filter substrate 22 in this direction, thereby forming an exposed structure at the edge of the display panel 2 that can be connected. The provision of the first extension 211 means that the edge of the array substrate 21 does not need to be completely covered by the color filter substrate 22, thereby providing installation space for the subsequent application of the conductive adhesive 3.

[0026] For example, the conductive adhesive 3 is connected to the outer wall of the first extension 211, and simultaneously connects the color filter substrate 22 and the frame 1.

[0027] Furthermore, the conductive adhesive 3 can be an adhesive material containing conductive particles, such as silver paste, carbon-based conductive adhesive 3, or other composite adhesive materials that can simultaneously provide conductivity and adhesion. The outer wall of the first extension 211 can be understood as the side wall area of ​​the first extension 211 facing the outside of the display panel 2, and may also include the edge corner area. During the coating process, the conductive adhesive 3 can be adhered to the outer wall of the first extension 211 by dispensing, line coating, or scraping, and further extend to the edge of the color filter substrate 22 and the corresponding position of the frame 1, thereby forming a connection structure spanning the first extension 211, the color filter substrate 22, and the frame 1. Since the conductive adhesive 3 itself has a certain conductivity, when there is static electricity accumulation at the edge of the display panel 2, the static electricity can be conducted through the first extension 211 to the conductive adhesive 3, and then further transferred to the frame 1, thereby helping to reduce the risk of static electricity accumulation in the edge area and improve the static electricity protection capability of the edge area of ​​the display panel 2.

[0028] It is understandable that, since the conductive adhesive 3 connects the first extension 211, the color filter substrate 22, and the frame 1 simultaneously, the conductive adhesive 3 can also perform structural fixing functions in addition to its conductive function. In traditional solutions, it is usually necessary to additionally apply aluminum foil edge-wrapping adhesive to cover the edges of the display panel 2 to achieve light shielding, light leakage prevention, and structural fixing. However, the cost of aluminum foil edge-wrapping adhesive is relatively high, and the application process is relatively complex.

[0029] Based on this, after the conductive adhesive 3 covers the outside of the first extension 211, it can shield the edge gaps of the display panel 2, making it less likely for external light to enter the display area along the gaps, thus helping to reduce light leakage. Simultaneously, after the conductive adhesive 3 connects the color filter substrate 22 to the frame 1, it enhances the bonding stability between the display panel 2 and the frame 1, reducing the need for additional edge fixing components. Since the same material simultaneously performs the functions of electrostatic conduction, edge shielding, and structural fixation, the overall material types are relatively fewer, the assembly process is simplified, and production costs are further reduced.

[0030] Furthermore, the structure of the first extension 211 protruding from the end face of the color filter substrate 22 can improve the adhesion reliability of the conductive adhesive 3. Compared to the structure where the end face of the color filter substrate 22 is flush with that of the array substrate 21, the protruding first extension 211 can form a more obvious adhesive-containing area. After curing, the conductive adhesive 3 can form a more stable encapsulation relationship with the first extension 211, reducing the risk of adhesive displacement or detachment. For the miniaturization and narrow bezel design of display devices, this structure can meet the requirements of fixation, conductivity, and light shielding within a limited edge space, and has good application value.

[0031] In some implementations, combined Figure 1 , Figure 2 and Figure 3 The first extension 211 defines a first groove 4 between the side of the frame 1 away from the first extension 211 and the end face of the color filter substrate 22. The first groove 4 can be understood as a clearance space formed between the protruding structure of the first extension 211 and the edge of the color filter substrate 22. The clearance space can be continuously set along the edge direction of the display panel 2 or set at intervals. Specifically, it can be adjusted according to the dotted position of the conductive adhesive 3.

[0032] For example, the first groove 4 is located at the connection edge region between the array substrate 21 and the color filter substrate 22 in the thickness direction of the display panel 2, and is adjacent to the outer wall of the first extension 211, thereby forming an additional colloid accommodating space at the edge of the display panel 2. Part of the conductive adhesive 3 is disposed in the first groove 4 and connects the array substrate 21 and the color filter substrate 22. That is, while covering the outer wall of the first extension 211, the conductive adhesive 3 can also extend into the first groove 4 and fill the gap between the end face of the first extension 211 and the color filter substrate 22.

[0033] Because the first groove 4 provides additional space for dispensing, the conductive adhesive 3 has a more defined flow path and containment area during the coating process, which reduces the possibility of disordered diffusion of the adhesive at the panel edge and helps improve the stability of the dispensing position. Simultaneously, after entering the first groove 4, the conductive adhesive 3 can form an additional connection area between the array substrate 21 and the color filter substrate 22, thereby enhancing the bonding stability at their edge positions. Compared to structures with smaller edge spaces, the first groove 4 provides more ample space for the conductive adhesive 3, improving the reliability of edge encapsulation while maintaining conductive connection functionality.

[0034] In some implementations, combined Figure 2 and Figure 3 The polarizing layer 23 has a second extension 231 that protrudes from the end face of the color filter substrate 22. Specifically, the second extension 231 can be understood as a protruding area formed by the edge of the polarizing layer 23 extending outward relative to the color filter substrate 22. This protruding area can be formed by cutting the polarizer to a size larger than the edge size of the color filter substrate 22, or it can be formed by adjusting the attachment position to form an outward structure.

[0035] For example, the first extension 211 protrudes outward on one side of the color filter substrate 22, and the second extension 231 protrudes outward on the other side of the color filter substrate 22. The first extension 211, the end face of the color filter substrate 22 and the second extension 231 together define the first groove 4. The first groove 4 can be understood as a space for adhesive extending along the edge of the display panel 2. The conductive adhesive 3 can be filled inside the first groove 4 and connect the polarizing layer 23, the color filter substrate 22 and the array substrate 21, thereby forming a multilayer connection structure at the edge of the display panel 2.

[0036] Since the first groove 4 has a relatively clear boundary range, the conductive adhesive 3 can preferentially flow into the interior of the first groove 4 after being applied, thereby obtaining a stable containment space, which is beneficial to improving the controllability of the dispensing position.

[0037] Meanwhile, the second extension 231, located near the display side of the first groove 4, can provide some obstruction to the conductive adhesive 3. When the conductive adhesive 3 has a tendency to flow before curing, the second extension 231 can reduce the possibility of the conductive adhesive 3 diffusing towards the front side of the polarizing layer 23, thereby helping to mitigate the adverse effects of adhesive overflow on the appearance of the display area. In addition, after the conductive adhesive 3 connects the polarizing layer 23, the color filter substrate 22, and the array substrate 21, the bonding relationship between the multilayer structures at the edge of the display panel 2 is more stable, which has a positive effect on improving the reliability of edge packaging.

[0038] In some implementations, combined Figure 2 , Figure 3The end face of the first extension 211 and the outer wall of the frame 1 near the array substrate 21 form a second groove 5. Specifically, the second groove 5 can be understood as a clearance space provided on the lower side of the edge of the display panel 2. This space is located between the first extension 211 and the frame 1. Specifically, it can be continuously provided along the circumference of the display panel 2, or it can be locally provided according to the dispensing process requirements.

[0039] For example, the first groove 4 and the second groove 5 are connected, that is, the space in the first groove 4 and the space in the second groove 5 form a continuous adhesive channel in the edge area. After the conductive adhesive 3 is applied, it can flow from the first groove 4 to the second groove 5, or it can directly fill the interior of the second groove 5.

[0040] Furthermore, a portion of the conductive adhesive 3 is disposed in the second groove 5 and connects the array substrate 21 and the frame 1, thereby forming a conductive connection and structural connection on the lower edge of the display panel 2. Since the second groove 5 is reserved between the first extension 211 and the frame 1, the conductive adhesive 3 has a more defined placement space between the array substrate 21 and the frame 1, which reduces the possibility of disorderly diffusion of the adhesive to other areas during assembly and helps improve dispensing accuracy.

[0041] Meanwhile, after the conductive adhesive 3 is filled into the second groove 5, it can enhance the connection stability between the array substrate 21 and the frame 1, and further extend the conductive path, which is beneficial to the edge electrostatic conduction and the overall packaging stability.

[0042] In some implementations, combined Figure 2 , Figure 3 The first extension 211 defines an overflow groove 6 between the side facing away from the color filter substrate 22 and the frame 1. The overflow groove 6 can be understood as an excess glue accommodating space provided below the edge of the display panel 2. This space is located between the outer region of the first extension 211 and the frame 1, and communicates with the second groove 5.

[0043] It is understandable that when the amount of conductive adhesive 3 in the second groove 5 is large, the adhesive has strong fluidity, or the assembly extrusion effect is obvious, some of the excess conductive adhesive 3 may continue to flow outward. At this time, the excess conductive adhesive 3 can enter the overflow groove 6 for containment.

[0044] For example, a portion of the conductive adhesive 3 is disposed in the overflow groove 6 and connects the array substrate 21 and the frame 1. This means that while the conductive adhesive 3 completes the connection between the array substrate 21 and the frame 1, the remaining amount of adhesive can be guided into a preset space. Because the overflow groove 6 provides an additional adhesive-containing area, the excess flow of the conductive adhesive 3 before curing has a release path, thereby reducing the possibility of the conductive adhesive 3 continuing to diffuse to the outside of the display device. This helps mitigate the risk of edge appearance contamination and improves the stability of the dispensing process in the edge area. For mass production scenarios, when there are certain process fluctuations in the dispensing amount, the overflow groove 6 can also provide a certain degree of process tolerance, thereby improving the consistency of product assembly.

[0045] In some implementations, combined Figure 2 , Figure 3 The frame 1 includes a plastic frame 11 and a back plate 12. The plastic frame 11 is embedded in the back plate 12. The plastic frame 11 can be understood as a buffer support structure that directly cooperates with the edge of the display panel 2. The back plate 12 can be understood as a load-bearing component used to improve the overall structural strength.

[0046] For example, the end face of the frame 11 near the first extension 211 is a slope 111, and the slope 111 and the side of the first extension 211 away from the color filter substrate 22 define an overflow groove 6. The slope 111 can be understood as a transition surface with an inclination angle relative to a vertical plane or a flat plane, and this inclination angle can be set according to the flow characteristics of the conductive adhesive 3. Compared with a straight structure, the slope 111 can expand the space between the first extension 211 and the frame 11, thereby increasing the volume of the overflow groove 6. When the conductive adhesive 3 enters the overflow groove 6, the slope 111 can provide a longer flow path and a larger accommodating area for the adhesive, which is beneficial to improving the excess adhesive containment capacity. At the same time, the slope 111 structure can also reduce the possibility of a large accumulation of conductive adhesive 3 in a local area, thereby mitigating the impact of excessive adhesive accumulation on the assembly flatness, and further improving the stability and appearance quality of the edge structure of the display device.

[0047] In some embodiments, the distance between the end face of the first extension 211 and the end face of the color filter substrate 22 ranges from 0.1mm to 0.3mm. This distance can be understood as the length of the first extension 211 protruding outward relative to the edge of the color filter substrate 22. If the distance is too small, the exposed area formed by the first extension 211 is relatively limited, the adhesion area of ​​the conductive adhesive 3 at the edge is relatively small, and the adhesive-containing space of the first groove 4 may also be insufficient, which is not conducive to the stable placement of the conductive adhesive 3. If the distance is too large, the redundant space at the edge of the display panel 2 increases, which may affect the narrow bezel design, and the material utilization rate is relatively reduced. Controlling the distance within the range of 0.1mm to 0.3mm can form a more balanced matching relationship between the edge space utilization rate and the conductive adhesive 3 placement requirements, thereby helping to balance the stability of conductive connection and the requirements for thinner and lighter display devices.

[0048] Furthermore, the distance between the end face of the second extension 231 of the polarizing layer 23 and the end face of the color filter substrate 22 is also within the range of 0.1mm to 0.3mm. This distance can be understood as the outward protrusion dimension of the second extension 231. When this distance is too small, the limiting effect of the second extension 231 on the conductive adhesive 3 in the first groove 4 is relatively limited, and the risk of the conductive adhesive 3 spreading to the display side may increase. When this distance is too large, the protruding area at the edge of the polarizing layer 23 is too long, which may affect the edge adhesion accuracy of the display panel 2. By limiting this distance to the range of 0.1mm to 0.3mm, the second extension 231 can provide a relatively stable boundary structure for the first groove 4 and maintain good structural compactness at the display edge, thereby improving the overflow control effect of the conductive adhesive 3 and the display appearance quality.

[0049] In some implementations, combined Figure 1 , Figure 2 and Figure 3 The display device also includes a backlight assembly 7, which is connected within the frame 1. The backlight assembly 7 includes a reflective sheet 71, a light guide plate 72, and a film 73, which are stacked sequentially along a direction perpendicular to and facing the light-emitting surface. The light-emitting surface can be understood as the side of the display device facing the user. The reflective sheet 71 is used to reflect light propagating away from the display panel 2 back to the area of ​​the light guide plate 72. The light guide plate 72 is used to uniformly guide the light emitted by the light source. The film 73 may include a brightness enhancement film, a diffusion film, or other optical film materials to further optimize the uniformity of light emission. After the backlight assembly 7 is combined with the frame 1, it can form a complete liquid crystal display module together with the display panel 2. Since the conductive adhesive 3 replaces the traditional aluminum foil edge-wrapping adhesive, the edge structure of the display panel 2 is simplified, and the assembly space between it and the backlight assembly 7 is utilized more efficiently. This is beneficial for the overall thinner and lighter design of the display device, while also meeting the requirements of edge conductivity, light leakage prevention, and display functionality.

[0050] In some implementations, combined Figure 1 , Figure 2 and Figure 3 The display device also includes a single-sided adhesive tape 8, with its first end connected to a film 73 and its second end connected to a frame 11. The single-sided adhesive tape 8 can be understood as an adhesive structure with adhesion properties on only one side, while the other side can be a substrate layer, a release layer, or a support layer without adhesive function. The film 73 can be a brightness enhancement film, a diffusion film, or a composite optical film layer in the backlight assembly 7, and the frame 11 can be an edge support structure in the frame 1 used to support the display panel 2 and the backlight assembly 7. After the single-sided adhesive tape 8 is placed between the film 73 and the frame 11, it can limit and fix the edge position of the film 73, thereby reducing the possibility of the film 73 shifting during transportation, assembly, or long-term use.

[0051] It is worth noting that, in the aforementioned structure, the frame 1 has already formed a connection with the array substrate 21 through the conductive adhesive 3, and the edge fixing function of the display panel 2 has been undertaken by the conductive adhesive 3. Therefore, it is no longer necessary to connect the display panel 2 and the frame 1 simultaneously through traditional double-sided adhesive.

[0052] Therefore, compared to the double-sided adhesive structure, the single-sided adhesive 8 only needs to complete the function of fixing the diaphragm 73 and the adhesive frame 11. Its structure is simpler and the amount of material used is relatively less.

[0053] Meanwhile, the single-sided adhesive 8 is only applied to the backlight component 7, which reduces the thickness of the adhesive layer at the edge of the display panel 2, thus optimizing the utilization of edge space. For the display module assembly process, the application position of the single-sided adhesive 8 is more clearly defined, and the assembly process is relatively simplified, thereby reducing material and assembly costs and improving the overall lightweighting of the display device.
