[0057] The realization, functional features and advantages of the present invention will be further described in conjunction with embodiments and with reference to the accompanying drawings. Specific embodiments

[0058] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0059] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All the embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0060] It should be noted that the descriptions involving "first", "second", etc. in the embodiments of the present invention are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments may be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0061] Refer to Figure 1 , Figure 1 is a schematic structural diagram of the first embodiment of the tape structure of the present invention.

[0062] As Figure 1 shown, in this embodiment, the tape structure is used to bond a rubber frame and a display panel, and the tape structure includes: a first adhesive sheet 301 and a second adhesive sheet 302.

[0063] Wherein, a cavity 400 is formed between the first adhesive sheet 301 and the second adhesive sheet 302; a solution 402 composed of electromagnetic particles 401 is provided in the cavity 400, and the solution 402 is used to adjust the hardness of the tape structure.

[0064] It should be noted that the above-mentioned first adhesive sheet 301 and the above-mentioned second adhesive sheet 302 can be patches with adhesive materials attached to both sides, and the adhesive materials can bond two or more non-connected objects together. That is, both the front and back sides of the above-mentioned first adhesive sheet 301 and the above-mentioned second adhesive sheet 302 can be adhered to other objects, such as double-sided tape.

[0065] It is understandable that the above-mentioned cavity can be formed by enclosing multiple conductive substrates, and one side of the cavity is adhered to one side of the above-mentioned first adhesive sheet 301, and the other side is adhered to one side of the above-mentioned second adhesive sheet 302. Among them, one side of the above-mentioned first adhesive sheet 301 can be adhered to a conductive substrate to form an integral body, and one side of the above-mentioned second adhesive sheet 302 can be adhered to another conductive substrate to form an integral body. In this way, by setting several more conductive substrates, a cavity with an enclosed structure can be formed, and this cavity is located between the first adhesive sheet 301 and the second adhesive sheet 302 of the tape structure.

[0066] It should be noted that the above-mentioned electromagnetic particles 401 can be particles for controlling the hardness of the tape structure. The electromagnetic particles 401 can be positively charged particles or negatively charged particles. The arrangement direction of the electromagnetic particles 401 can be affected by an electric current or an electric field. Specifically, the greater the electric current, the more the electromagnetic particles 401 shift towards the direction of the electric current, and the arrangement becomes orderly, making the tape structure harder. On the contrary, the smaller the electric current, the easier it is to maintain the current position, and the arrangement becomes disorderly, making the tape structure softer.

[0067] It is understandable that the above-mentioned solution 402 can be a conductive solution for storing the above-mentioned electromagnetic particles 401, such as an oil solution. This solution 402 can serve as a conductive medium. When the cavity 400 is powered on, an electric current can flow into this solution 402, thus forming a circuit. The arrangement position of the electromagnetic particles 401 can be affected by the input electric current. Among them, since there is a liquid solution in the cavity 400 in the middle of the tape structure, the softness of the tape structure can be better, effectively reducing the risk of light leakage.

[0068] It should be noted that a rubber frame can be set at the position where the above-mentioned backlight module faces the array substrate. The above-mentioned tape structure can be arranged in this rubber frame, and the second adhesive sheet 302 of the tape structure is adhered to the rubber frame, and the first adhesive sheet 301 of the tape structure can be adhered to the array substrate on the back of the display panel, thereby fitting the display panel and the backlight module.

[0069] For the sake of easy understanding, reference is made to Figure 2 for illustration, but this solution is not limited. Figure 2 This is a schematic diagram of the arrangement of electromagnetic particles in the first embodiment of the tape structure of the present invention. Figure 2 In it, the electromagnetic particles 401 are in a disordered arrangement state in the cavity 400 in the natural state. At this time, the hardness of the tape structure reaches the lowest, and the tape structure is relatively soft. Correspondingly, Figure 1 The electromagnetic particles 401 shown in it are in an ordered arrangement state. At this time, the hardness of the tape structure reaches the highest, and the tape structure is relatively hard.

[0070] For the sake of easy understanding, reference is made to Figure 3 for illustration, but this solution is not limited. Figure 3This is a schematic structural diagram of the foam tape in the first embodiment of the tape structure of the present invention. Figure 3 In it, the existing foam tape is in the glue frame 202, and the display panel can be attached to the glue frame 202. Since the foam tape 311 is provided in the glue frame 202, the foam tape can adhere to the display panel, thereby attaching the backlight module and the display panel. However, since the foam tape 311 is relatively hard and its hardness cannot be adjusted, it cannot be bent. And the glue frame 202 is generally a rectangular structure, so that the foam tape 311 needs to be separately provided in multiple segments at the corners, that is, in a segmented manner. Therefore, a horizontal section and a vertical section need to be provided at the corners of the glue frame 202, resulting in a gap at the corners. After attaching the display panel, this gap cannot be attached to the liquid crystal display panel, resulting in light leakage on the front side of the LCM.

[0071] For the sake of easy understanding, reference is made to Figure 4 for illustration, but the present solution is not limited thereby. Figure 4 This is a top view of the first embodiment of the tape structure of the present invention. Figure 4 In it, when the tape structure 300 proposed in this embodiment attaches the display panel and the glue frame 202, it can also be in the glue frame 202 like the foam tape 311. A solution 402 composed of electromagnetic particles is provided in the tape structure 300 of this embodiment. These electromagnetic particles are in a disordered arrangement in the natural state. The tape structure 300 is relatively soft and can be bent at the corners, so that the tape structure 300 in the glue frame 202 is integral and completely covers the glue frame 202 without generating gaps, thereby avoiding the problem of gaps existing in the segmented setting of the foam tape 311, and the display panel can completely cover the glue frame 202.

[0072] It should be noted that the positions where the above tape structure 300 adheres externally can be the outer sides of the first adhesive sheet 301 and the second adhesive sheet 302. The above tape structure can be located in the glue frame 202, and the outer side of the second adhesive sheet 302 can adhere to the glue frame 202, and the glue frame 202 is located in the backlight module, so as to adhere to the backlight module. The outer side of the above first adhesive sheet 301 can adhere to the array substrate on the back of the display panel, so as to adhere to the display panel, thereby attaching the display panel and the backlight module.

[0073] For the sake of easy understanding, reference is made to Figure 5 for illustration, but the present solution is not limited thereby. Figure 5 This is a cross-sectional view of the first embodiment of the tape structure of the present invention. Figure 5 It can be a cross-sectional view obtained by intercepting along the Figure 4 section direction AB in Figure 5In the figure, the tape structure 300 is located between the display panel 100 and the rubber frame 202. One side of the tape structure 300 is adhered to the display panel 100, and the other side is adhered to the rubber frame 202. The rubber frame 202 is located on the backplane 201, and the backplane 201 is the backplane of the backlight module. Therefore, through the tape structure 300, the adhesion between the display panel 100 and the backlight module is realized, so that the light source of the backlight module can enter the display panel 100, enabling the LCD to achieve the display function.

[0074] In specific implementation, when the hardness of the tape structure is relatively hard and the display panel 100 is deformed, the arrangement of the electromagnetic particles can be adjusted to be in a disordered state, that is, the arrangement direction becomes irregular, making the tape structure softer, thereby changing the deformation of the display panel 100, better fitting the tape structure 300, and avoiding the deformation of the display panel 100 caused by being pulled and deformed, which may lead to light leakage on the front side of the liquid crystal module.

[0075] It should be understood that the above rubber frame 202 itself will also deform. After being attached to the display panel 100, the foam tape 311 pulls the liquid crystal layer 100, resulting in deformation. Correspondingly, the foam tape 311 itself will also deform. After being attached to the display panel 100, it will also pull the display panel 100, resulting in deformation. The above situations will ultimately cause light leakage on the front side of the LCM. In this embodiment, the above tape structure 300 adjusts its own hardness when the display panel 100 is deformed to improve the deformation of the display panel 100, effectively avoiding the deformation caused by the deformation of the rubber frame 202 or the tape pulling the display panel 100, and further avoiding the light leakage on the front side of the LCM, effectively improving the display quality of the display panel 100.

[0076] The tape structure of this embodiment is used to attach the rubber frame and the display panel, including: a first adhesive sheet and a second adhesive sheet; a cavity is formed between the first adhesive sheet and the second adhesive sheet; a solution composed of electromagnetic particles is provided in the cavity, and the solution is used to adjust the hardness of the tape structure. In the tape structure of this embodiment for attaching the rubber frame and the array substrate, a solution composed of electromagnetic particles is provided. Compared with the problem that the foam tape used in the existing attachment method is relatively hard and will pull the display panel during the attachment process with the display panel, causing the liquid crystal layer in the display panel to deform, and further resulting in light leakage on the front side of the LCM and affecting the display quality of the display panel, the above tape structure of this embodiment adjusts the hardness of the tape structure through the solution composed of electromagnetic particles, reducing the stress of the tape structure on the display panel, thereby reducing the deformation degree of the liquid crystal layer, avoiding the light leakage on the front side of the LCM, and effectively improving the display quality of the display panel.

[0077] Reference Figure 6 , Figure 6 is the first structural schematic diagram of the second embodiment of the tape structure of the present invention.

[0078] Based on the above first embodiment, in this embodiment, the tape structure further includes: a sensor 500.

[0079] Wherein, the sensor 500 is disposed between the first adhesive sheet 301 and the cavity 400 and is electrically connected to the processing chip; the processing chip is also electrically connected to the cavity 400.

[0080] The sensor 500 is used to detect whether the liquid crystal layer in the display panel 100 is deformed and feedback the detection result to the processing chip.

[0081] In a specific implementation, the above-mentioned sensor 500 can be disposed on one surface of the array substrate in the above-mentioned display panel 100, and this one surface can be the side of the array substrate facing the first adhesive sheet 301. When the liquid crystal layer in the display panel 100 is deformed, it can be detected by the sensor 500, and then the detection result is fed back to the above-mentioned processing chip.

[0082] The processing chip is used to adjust the magnitude of the current input to the cavity 400 when the detection result is that the liquid crystal layer is deformed, so as to control the arrangement position of the electromagnetic particles 401, and the arrangement position of the electromagnetic particles 401 affects the hardness of the tape structure.

[0083] It should be noted that the above-mentioned sensor 500 is disposed between the first adhesive sheet 301 and the cavity 400, and does not affect the adhesion between the first adhesive sheet 301 and the display panel 100 when detecting whether the liquid crystal layer of the display target is deformed, avoiding the influence of the sensor 500 on the adhesion effect of the tape structure.

[0084] In a specific implementation, the above-mentioned processing chip is electrically connected to the above-mentioned cavity 400 and can output current to the cavity 400. When the detection result fed back by the sensor 500 is that the liquid crystal layer is deformed, the processing chip can judge whether the amount of deformation reaches a preset threshold. If it reaches the preset threshold, it can be determined that the amount of deformation is too large and may cause the LCM to leak light. In order to avoid the LCM from leaking light, the magnitude of the current output to the cavity 400 can be adjusted to make the arrangement of the electromagnetic particles 401 more disordered, making the tape structure softer, so that the stress of the tape structure 300 pulling on the display panel 100 is reduced, and further reducing the degree of deformation of the liquid crystal layer, that is, reducing the amount of deformation of the liquid crystal layer.

[0085] It should be understood that the above-mentioned electromagnetic particles 401 can be affected by the current input to the cavity 400. The greater the current, the more the electromagnetic particles 401 will tend to the current direction and become more ordered, making the tape structure harder. Correspondingly, the smaller the current, the more the electromagnetic particles 401 will deviate from the current direction and become more disordered, making the tape structure softer.

[0086] It should be noted that the above preset threshold can be the minimum value of the deformation amount of the liquid crystal layer that causes light leakage in the LCM. That is, if the current deformation amount reaches this preset threshold, it can be determined that the current deformation amount can cause light leakage in the LCM. On the contrary, if the current deformation amount does not reach this preset threshold, it can be determined that the current deformation amount is not sufficient to cause light leakage in the LCM, and no adjustment is required.

[0087] It should be understood that the above processing chip can also be integrated in the OC chip that controls the liquid crystal in the display panel 100 and directly controlled through the OC chip, effectively reducing the number of control chips, thus simplifying the circuit structure and reducing the cost.

[0088] In this embodiment, the sensor 500 is used to detect in real time whether the liquid crystal layer deforms, and then feeds back the detection result to the processing chip. When the detection result is that the liquid crystal layer deforms, the processing chip controls the arrangement position of the above electromagnetic particles, thereby changing the hardness of the tape structure 300, reducing the stress of the tape structure 300 pulling on the display panel 100, thus reducing the deformation degree of the liquid crystal layer, enabling the display panel 100 to better fit the tape structure 300, and avoiding light leakage on the front side of the liquid crystal module caused by the display panel 100 being pulled and deformed.

[0089] Further, referring to Figure 7 , Figure 7 is the second structural schematic diagram of the second embodiment of the tape structure of the present invention. In this embodiment, the tape structure further includes: a sensor 500.

[0090] A number of grooves are provided in the area between the first adhesive sheet 301 and the display panel 100; the sensor 500 is disposed in the grooves and is flush with the first adhesive sheet 301; the sensor 500 is also electrically connected to the processing chip, and the processing chip is also electrically connected to the cavity 400.

[0091] The sensor 500 is used to detect whether the liquid crystal layer in the display panel 100 deforms and feed back the detection result to the processing chip.

[0092] The processing chip is used to adjust the magnitude of the current input to the cavity 400 when the detection result is that the liquid crystal layer deforms, so as to control the arrangement position of the electromagnetic particles 401, and the arrangement position of the electromagnetic particles 401 affects the hardness of the tape structure.

[0093] It should be noted that the functions of the above sensor 500 and processing chip are both the same as those of the sensor 500 and processing chip in Figure 6 , and reference can be made to the description of Figure 6 , and details will not be repeated here.

[0094] In specific implementation, such as Figure 7As shown, different from the sensor 500 in Figure 6 being disposed between the first adhesive sheet 301 and the cavity 400, Figure 7 in the structure shown in Figure 7 , a plurality of grooves are provided in the region between the first adhesive sheet 301 and the display panel 100, the sensor 500 is disposed in the grooves and is flush with the first adhesive sheet 301. Since the sensor 500 is flush with the first adhesive sheet 301 and the first adhesive sheet 301 is adhered to the display panel 100, therefore, the sensor 500 also contacts the display panel 100 and can accurately detect whether the liquid crystal layer in the display panel 100 is deformed.

[0095] Furthermore, since the sensor 500 is in the groove in the first adhesive sheet 301 and the grooves are intermittently arranged, therefore, the sensor 500 located in the grooves does not affect the adhesion effect of the first adhesive sheet 301. While ensuring that the sensor 500 accurately detects whether the liquid crystal layer of the display panel 100 is deformed, it will not affect the adhesion effect of the tape structure. At the same time, since the sensor 500 is in the groove of the first adhesive sheet 301, the problem that there will be a gap between the sensor 500 and the first adhesive sheet 301 is avoided, and the tape structure 300 and the display panel 100 can be just connected together, improving the detection accuracy of the sensor 500.

[0096] It should be understood that the above tape structure 300 is disposed in the rubber frame 202. Therefore, the second adhesive sheet 302 of the tape structure 300 needs to be adhered to the above rubber frame 202 to make the tape structure 300 stable in the rubber frame 202. And, the rubber frame 202 is on the backlight module. Then, the display panel 100 and the backlight module can be adhered through the tape structure 300, so that the display panel 100 can receive the light source in the backlight module and obtain the display function.

[0097] Furthermore, in this embodiment, the tape structure further includes: a plurality of soft partitions 600.

[0098] Wherein, each of the soft partitions 600 is disposed in the cavity 400 at intervals and divides the cavity 400 into several regions corresponding to the grooves; the processing chip is respectively connected to the electrodes disposed on each of the regions.

[0099] It should be noted that the above soft partition 600 can be a micro-structure of a soft material. The soft partition 600 can play an isolation role in the cavity 400.

[0100] It can be understood that when the liquid crystal layer is deformed, it is generally a local deformation, not an overall deformation. Therefore, it is not necessary to adjust the hardness of the tape structure 300 as a whole, and only the position corresponding to the deformed liquid crystal layer region in the tape structure 300 needs to be adjusted.

[0101] In a specific implementation, a plurality of flexible partitions 600 are arranged in the cavity 400. The cavity 400 is isolated by the flexible partitions 600 to divide a plurality of regions, and each region corresponds to a groove, that is, each region corresponds to a sensor. Electrodes are arranged on each region, and then the processing chip is respectively connected to the electrodes on each region, and the processing chip can separately control each region of the cavity 400. When the sensor 500 corresponding to a certain region detects that the liquid crystal layer deforms, the processing chip can adjust the magnitude of the current output to the cavity region corresponding to the deformed region of the display panel 100, and adjust the hardness of the position corresponding to the deformed region on the tape structure, so that the deformed region returns to normal. For the cavity regions that do not deform, the hardness of the tape structure is not adjusted, so as to more precisely adjust the tape region and accurately improve light leakage.

[0102] In addition, to achieve the above object, the present invention further provides a control method, which is applied to the tape structure described in the above embodiment. Refer to Figure 8 , Figure 8 which is a schematic flowchart of an embodiment of the control method of the present invention.

[0103] As Figure 8 shown, the method further includes:

[0104] Step S10: Detect the liquid crystal layer in the display panel to obtain a detection result.

[0105] It should be noted that the execution subject of the control method in this embodiment can be a control device or chip with control and program running functions. The following takes the above processing chip as an example to illustrate this embodiment. The processing chip is electrically connected to the cavity in the tape structure, and adjusts the hardness of the tape structure by outputting current to the cavity.

[0106] In a specific implementation, the sensor in the tape structure can detect in real time whether the liquid crystal layer in the above display panel deforms, and feedback the detection result to the above processing chip. The detection result can be that the liquid crystal layer deforms or the liquid crystal layer does not deform. And if the liquid crystal layer deforms, the detection result can also include the amount of deformation.

[0107] Step S20: When the detection result is that the liquid crystal layer deforms, adjust the hardness of the tape structure.

[0108] In a specific implementation, when the detection result is that the liquid crystal layer deforms, the above processing chip can adjust the hardness of the tape structure by adjusting the magnitude of the current output to the cavity in the above tape structure.

[0109] Further, in this embodiment, the step S20 includes:

[0110] Step S201: When the detection result indicates that the liquid crystal layer is deformed, determine whether the amount of deformation of the liquid crystal layer reaches a preset threshold.

[0111] It should be noted that the above preset threshold can be the minimum value of the amount of deformation of the liquid crystal layer that causes light leakage in the LCM. That is, if the current amount of deformation reaches this preset threshold, it can be determined that the current amount of deformation can cause light leakage in the LCM. On the contrary, if the current amount of deformation does not reach this preset threshold, it can be determined that the current amount of deformation is not sufficient to cause light leakage in the LCM and no adjustment is required.

[0112] In a specific implementation, when the above detection result indicates that the liquid crystal layer is deformed, the above processing chip can extract the amount of deformation in the above detection result, and then determine whether the amount of deformation reaches a preset threshold. If it reaches this preset threshold, it can be determined that the amount of deformation is too large and can cause light leakage in the LCM.

[0113] Step S202: If it reaches, reduce the magnitude of the current input to the electromagnetic particles in the tape structure, so that the electromagnetic particles deviate from the current arrangement position, and the hardness of the tape structure decreases when the electromagnetic particles deviate from the current arrangement position.

[0114] In a specific implementation, after the above processing device detects that the above amount of deformation reaches the above preset threshold, it can adjust the current input to the cavity of the above tape structure, so that the current received by the electromagnetic particles decreases, causing the electromagnetic particles to deviate from the current arrangement position and become more disordered, thereby reducing the hardness of the tape structure, improving the deformation of the liquid crystal layer, and further avoiding front light leakage in the LCM.

[0115] It should be understood that the above electromagnetic particles are particles in the cavity and can be affected by the current input to the cavity. The greater the current, the more the electromagnetic particles will tend to the current direction and become more ordered, making the tape structure harder. Correspondingly, the smaller the current, the more the electromagnetic particles will deviate from the current direction and become more disordered, making the tape structure softer.

[0116] For ease of understanding, reference Figure 9 is made for illustration, but the present solution is not limited thereby. Figure 9 is the overall flowchart of the embodiment of the control method of the present invention. Figure 9 In it, first, the sensor detects whether the liquid crystal layer is deformed, and then feeds back the detection result to the processing chip. When the processing chip determines that the liquid crystal layer is deformed, it can adjust the magnitude of the current input to the electromagnetic particles, causing the arrangement of the electromagnetic particles to change, and thus causing the deformation of the liquid crystal layer to change when it occurs. Then, repeat the above step of the sensor detecting whether the liquid crystal layer is deformed. If it is detected that the liquid crystal layer is not deformed, the processing chip can determine that the panel has recovered from the deformation and does not adjust the magnitude of the current input to the electromagnetic particles.

[0117] This embodiment detects and feeds back the detection result of the liquid crystal layer by receiving the sensor; when the detection result is that the liquid crystal layer is deformed, it is determined whether the deformation amount of the liquid crystal layer reaches a preset threshold; if reached, the current input to the electromagnetic particles in the tape structure is reduced to make the electromagnetic particles deviate from the current arrangement position, thereby reducing the hardness of the tape structure, improving the deformation of the liquid crystal layer, and avoiding light leakage from the front of the LCM.

[0118] Furthermore, in this embodiment, the step S20 further includes:

[0119] Step S201 ′: when the detection result is that the liquid crystal layer is deformed, determining a target solution region in the tape structure corresponding to the deformed liquid crystal layer region.

[0120] In a specific implementation, the cavity in the tape structure can be divided into regions, and the processing chip can control each region separately. When the detection result shows that the liquid crystal layer is deformed, the specific deformation position of the liquid crystal layer can be determined, and then the cavity partition corresponding to the specific deformation position in the tape structure is determined, and the solution in the cavity partition can be the target solution region, so as to adjust the hardness of the tape structure in a targeted manner.

[0121] Step S202 ′: determining whether the deformation amount of the liquid crystal layer region reaches a preset threshold.

[0122] In a specific implementation, when the detection result shows that the liquid crystal layer has been deformed, the processing chip can extract the deformation amount of the specific deformation position in the detection result, and then determine whether the deformation amount reaches a preset threshold. If the preset threshold is reached, it can be determined that the deformation amount is too large and may cause light leakage in the LCM.

[0123] Step S203': if the condition is reached, then reduce the current input to the electromagnetic particles in the target solution region to make the electromagnetic particles deviate from the current arrangement position, and the hardness of the tape structure decreases when the electromagnetic particles deviate from the current arrangement position.

[0124] In a specific implementation, after detecting that the deformation amount reaches the preset threshold, the processing device can adjust the current input to the target solution area to reduce the current received by the electromagnetic particles in the target solution area, so that the electromagnetic particles in the target solution area deviate from the current arrangement position and become more disordered, thereby reducing the hardness of the area corresponding to the specific deformation position in the tape structure, so that the deformed area returns to normal, and for the undeformed cavity area, the hardness of the tape structure is not adjusted, so that the tape area can be adjusted more accurately and the light leakage can be accurately improved.
