[0035]

[0036] The objectives, features and advantages of the present application will be further illustrated in conjunction with the embodiments, with reference to the accompanying drawings. DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present application.

[0038] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement condition, etc. between components in a certain posture (as shown in the drawings), and if the certain posture changes, the directional indications also change accordingly.

[0039] In addition, if the embodiments of the present application involve descriptions of “first”, “second”, etc., the descriptions of “first”, “second”, etc. are only for description purposes, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features limited by “first” and “second” can explicitly or implicitly include at least one of the features. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the fact that a person skilled in the art can realize the combination, and when the combination of technical solutions contradicts each other or cannot be realized, it should be considered that the combination of technical solutions does not exist and is not within the protection scope of the present application.

[0040] Reference Figure 1 The technical problems proposed by the background art are described in detail.

[0041] Figure 1 The position of the foam glue in the display module is shown in the figure, the display panel is directly fixed on the module middle frame through the foam glue, and therefore the flatness of the display panel is affected by the module middle frame.

[0042] In the prior art, due to the part control of the module middle frame, the module middle frame is only allowed to be bowl-arched (the deformation state is concave deformation, that is, deformed to the side away from the display panel) but not allowed to be turtle-back-arched (the deformation state is convex deformation, that is, deformed to the side close to the display panel), so when the module middle frame is bowl-arched, the one side of the foam adhesive adhered to the module middle frame will bend downward, and then the other side of the foam adhesive adhered to the display panel will also bend downward, generating a concave deformation, which will generate a tensile stress acting on the corresponding position of the display panel, and the display panel will be deformed to a certain extent due to the tensile stress, and then the flatness of the display panel is destroyed, causing the display panel to have the phenomenon of light leakage during display.

[0043] The backlight module comprises a back plate 120, a reflective sheet 130, a light guide plate 140, an optical film 150 and a module middle frame 170, 160 as shown in the drawings. Figure 1

[0044] Referring to Figure 2 and Figure 3 , Figure 2 and Figure 3 are structural diagrams of the foam adhesive of the present application, the foam adhesive is attached to the module middle frame of the backlight module, so that the display panel can be fixed to the module middle frame through the foam adhesive, and the foam adhesive comprises a first adhesive layer 10, a control adjustment layer 30 and a second adhesive layer 20 which are sequentially stacked on the module middle frame.

[0045] The first adhesive layer 10 is used to be attached to the module middle frame, and the second adhesive layer 20 is used to be attached to the display panel, so that the display panel is fixed to the module middle frame.

[0046] The control adjustment layer 30 is connected to a control processor 90 on the display module, and is used to send deformation information to the control processor 90 when the foam adhesive generates concave deformation and drives the control adjustment layer 30 to generate concave deformation, receive a control instruction returned by the control processor 90 based on the deformation information, and perform a lifting operation on the position of the foam adhesive generating concave deformation according to the control instruction, the lifting operation being counteracted by at least part of the concave deformation.

[0047] According to Figure 1 ​To solve the problem shown, the embodiment proposes a foam glue with dynamic adjustment function, which focuses on the control adjustment layer 30 arranged in the foam glue. When the bowing of the middle frame of the module makes the side of the foam glue close to the middle frame of the module, i.e. the first adhesive layer 10, deform downward, because the foam glue is integral, the downward deformation of the first adhesive layer 10 will drive the second adhesive layer 20 to deform concavely. The control adjustment layer 30 arranged close to the second adhesive layer 20 can sense the concave deformation, generate deformation information according to the sensing result, and send the deformation information to the control processor 90 of the display module. After the control processor 90 processes the deformation information, the control adjustment layer 30 can receive the processing result of the control processor 90, i.e. the control instruction, and automatically adjust based on the control instruction, i.e. the control adjustment layer 30 can perform a lifting operation on the position of the foam glue with concave deformation based on the control instruction. The force of the lifting operation and the force of the concave deformation can offset each other, so that the side of the foam glue close to the display panel, i.e. the second adhesive layer 20, can maintain a relatively flat state, thereby eliminating the tensile stress of the second adhesive layer 20 on the display panel and maintaining the flatness of the display panel.

[0048] Figure 2 For Figure 1 The planar view of the foam glue in the A direction shows that the control adjustment layer 30 arranged in the foam glue of the embodiment is concentrated on the side of the foam glue close to the second adhesive layer 20, i.e. close to the display panel, to ensure that the lifting operation of the control adjustment layer 30 on the foam glue according to the control instruction is performed on the display panel.

[0049] Figure 3 For Figure 1 The planar view of the foam glue in the B direction shows that the control adjustment layer 30 arranged in the foam glue of the embodiment is laid on the side close to the display panel to ensure that the foam glue can compensate for the display position with deformation caused by the deformation of the middle frame of the module.

[0050] It should be noted that Figure 2 and Figure 3 The foam glue in the embodiment is improved foam glue, i.e. not the conventional foam glue in Figure 1 Figure 1 For Figure 2 and Figure 3 Only play a role in the planar direction.

[0051] Specifically, refer to Figure 4 and Figure 5 ​As shown, the control and adjustment layer 30 includes several control units 40, each of which consists of two sets of electrode units 50 and an insulating elastomer 60. The insulating elastomer 60 has several functional area cavities 70, and several negatively charged elastic balls 80 are distributed in the functional area cavities 70.

[0052] Furthermore, the functional area cavities 70 are connected by a pipe 100, and the negatively charged elastic spheres 80 flow between the functional area cavities 70 through the electrolyte solution in the pipe 100.

[0053] in accordance with Figure 4 The schematic diagram of the partial structure of the control and adjustment layer 30 designed in this embodiment in the foam adhesive shows that the control and adjustment layer 30 is composed of several control units 40. Each control unit 40 can dynamically adjust its corresponding display position on the display panel. By adjusting the block by several control units 40, the accuracy of adjusting the flatness of the display panel is improved.

[0054] The internal structures of the control units 40 installed in the control and regulation layer 30 are all identical, with Figure 5 The internal structure diagrams of any two control units 40 shown are used as examples for illustration.

[0055] Depend on Figure 5 It can be seen that the control unit 40 consists of two sets of paired symmetrical electrode units 50 and an insulating elastomer 60, wherein one set of paired symmetrical electrode units (i.e. Figure 5 a and b) in the figure encapsulate the insulating elastomer 60, and another component consists of symmetrical electrode units (i.e. Figure 5 c and d) are disposed inside the insulating elastomer 60 and enclose the functional area cavity 70 disposed inside the insulating elastomer 60.

[0056] The functional area cavities 70 in each control unit 40 are connected by a pipe 100, which is used to transport negatively charged elastic balls 80, so that the negatively charged elastic balls 80 in the functional area cavities 70 can circulate among the control units 40.

[0057] The control unit 40 mainly relies on the negatively charged elastic ball 80 to raise the concave deformation. The negatively charged elastic ball 80 is gathered by the electrode unit 50, and the gathered negatively charged elastic ball 80 raises the concave deformation.

[0058] It should be noted that, in order to ensure that there are enough negatively charged elastic balls 80 to lift the position where there is concave deformation, the functional area cavities 70 in each control unit 40 are interconnected through pipes 100 so that the negatively charged elastic balls 80 can flow in the functional area cavities 70 of each control unit 40.

[0059] Further, the deformation information includes a capacitance value, the electrode unit 50 includes a first electrode unit 501, the first electrode unit 501 is composed of a first electrode layer (i.e. Figure 5 a) in the formula (1) and a second electrode layer (i.e. Figure 5 b) in the formula (1);

[0060] The insulating elastic body 60 is arranged between the first electrode layer and the second electrode layer, the first electrode unit 501 and the insulating elastic body 60 constitute a capacitance sensor, wherein the electrode spacing between the first electrode layer and the second electrode layer will change with the concave deformation; the capacitance sensor is connected with the control processor 90, for sending the capacitance value which changes in real time according to the electrode spacing to the control processor 90.

[0061] Referring to Figure 5 , the electrode unit 50 arranged in the control unit 40 includes a first electrode unit 501 composed of a first electrode layer and a second electrode layer, wherein the first electrode layer is arranged on the side of the control unit 40 closest to the second adhesive layer 20, the second electrode layer is arranged on the side of the control unit 40 closest to the first adhesive layer 10, and the insulating elastic body 60 included in the control unit 40 is arranged between the first electrode layer and the second electrode layer, constituting a capacitance sensor for generating deformation information, i.e. for generating a capacitance value.

[0062] The spacing between the first electrode layer and the second electrode layer is the electrode spacing, according to the formula principle shown in the formula 1, it can be known that the capacitance value of the capacitance sensor changes with the change of the electrode spacing under the condition that the relative area between the first electrode layer and the second electrode layer is unchanged.

[0063] Specifically, referring to Figure 6As shown, because the deformation amount of the display panel is less than that of the module middle frame, when the side of the foam rubber close to the module middle frame (which can be regarded as the first adhesive layer 10) is deformed downward due to the existence of the bowl arch of the module middle frame, at this time, the side of the foam rubber close to the display panel (which can be regarded as the second adhesive layer 20) will be pulled by the force adhered to the display panel and the downward force of the first adhesive layer 10. When the downward force of the first adhesive layer 10 is greater than the force adhered to the display panel, at this time, the second adhesive layer 20 will be slightly concave, generating concave deformation. Because the deformation amount of the second adhesive layer 20 is less than that of the first adhesive layer 10, the electrode spacing d between the first electrode layer and the second electrode layer will increase, thereby causing the capacitance value of the capacitive sensor to change, and lowering its capacitance value. At the same time, the capacitive sensor will send the capacitance value to the judgment processing on the control processor 90 based on the connection relationship between the capacitive sensor and the control processor 90, so as to compensate for the concave deformation of the second adhesive layer 20, and avoid the problem of bending deformation of the display panel caused by the pulling of the display panel by the concave deformation.

[0064]

[0065] Wherein, C is the capacitance value, Q is the charge amount, U A -U B is the potential difference between the first electrode layer and the second electrode layer, ε r is the relative dielectric constant, S is the relative area of the first electrode layer and the second electrode layer, k is the electrostatic force constant, d is the electrode spacing, 4π is a constant, so, under the condition that ε r , S, k and 4π are fixed, C decreases with the increase of d.

[0066] Further, the control instruction includes a control voltage value, and the electrode unit 50 further includes a second electrode unit 502, which is arranged in the insulating elastic body 60. The second electrode unit 502 is composed of a third electrode layer (i.e. Figure 5 c) with positive polarity and a fourth electrode layer (i.e. Figure 5 d) with negative polarity.

[0067] The third electrode layer and the fourth electrode layer are provided with the functional area cavity 70, and the second electrode unit 502 is an electric field controller of the functional area cavity 70, wherein a plurality of negative electrically elastic small balls 80 distributed in the functional area cavity 70 will change with a control voltage difference between the third electrode layer and the fourth electrode layer, the electric field controller is connected with the control processor 90, and the electric field controller is used for respectively adjusting a voltage value of the third electrode layer and a voltage value of the fourth electrode layer according to the control voltage value transmitted by the control processor 90, so that the control voltage difference is increased, a plurality of negative electrically elastic small balls 80 are controlled to gather to the third electrode layer, and the lifting operation is performed on one side of the display panel close to the display panel.

[0068] Still referring to Figure 5 , the electrode unit 50 provided by the control unit 40 further includes a second electrode unit 502 composed of a third electrode layer and a fourth electrode layer, and the second electrode unit 502 is arranged in the insulating elastic body 60, wherein the third electrode layer is arranged on a side close to the first electrode layer, the fourth electrode layer is arranged on a side close to the second electrode layer, and the functional area cavity 70 arranged in the insulating elastic body 60 is arranged between the third electrode layer and the fourth electrode layer, and the third electrode layer and the fourth electrode layer constitute an electric field controller for controlling the flow direction of the negative electrically elastic small balls 80 in the functional area cavity 70 based on a control instruction, i.e., based on a control voltage value.

[0069] There is a control voltage difference between the third electrode layer with positive polarity and the fourth electrode layer with negative polarity, and the negative electrically elastic small balls 80 suspended in the functional area cavity 70 will dynamically flow with the change of the control voltage difference.

[0070] Referring to Figure 7 , when the electric field controller receives the control voltage value returned by the control processor 90 based on the capacitance value of the capacitance sensor changing with the concave deformation, the electric field controller will increase the control voltage difference between the third electrode layer and the fourth electrode layer based on the control voltage value, so that the negative electrically elastic small balls 80 in the functional area cavity 70 gather to the third electrode layer corresponding to the position of the concave deformation, and when the gathered negative electrically elastic small balls 80 exceed a certain amount, the negative electrically elastic small balls 80 will exert an upward force (i.e., N in Figure 7 ) on the position of the third electrode layer corresponding to the second adhesive layer 20, so that the second adhesive layer 20 is lifted upward, and the concave deformation is offset, so as to offset the pulling of the display panel caused by the concave deformation of the second adhesive layer 20.

[0071] Further, the foam tape further includes a foam tape base layer 110, and the foam tape base layer 110 is arranged between the control adjustment layer 30 and the first adhesive layer 10.

[0072] Referring toFigure 2 It can be known that the foam tape base layer 110 is arranged between the control adjustment layer 30 and the first adhesive layer 10, that is, away from the second adhesive layer 20, so as to avoid that the foam tape base layer 110 reduces the sensing effect of the control adjustment layer 30 on the concave deformation and reduces the compensation accuracy of the control adjustment layer 30 on the position of the concave deformation.

[0073] Specifically, referring to Figure 8 The control processor 90 is connected with each control unit 40 through a signal line L.

[0074] Each control unit 40 is connected with the control processor 90 through a signal line L, which can improve the accuracy of the control processor 90 in processing and controlling the control unit 40, and avoid control errors. Specifically, the signal line L is connected with the first electrode unit 501 and the second electrode unit 502 in the control unit 40.

[0075] Specifically, referring to Figure 9 The control processor 90 is connected with each control unit 40 through a signal line L.

[0076] Each control unit 40 is connected with the control processor 90 through a signal line L, which can avoid the wiring complexity of multiple lines and improve the wiring simplicity between the control unit 40 and the control processor 90. Specifically, the signal line L is connected with the first electrode unit 501 and the second electrode unit 502 in each control unit 40.

[0077] It should be noted that the electrode unit 50 and the signal line L in the present example are both made of ITO (Indium Tin Oxide), which is a kind of transparent conductive element.

[0078] Further, the control processor 90 is configured to:

[0079] When it is determined that the capacitance value sent by the control unit 40 is greater than the preset capacitance value, the control voltage value capable of making the concave deformation tend to be flat is returned to the control unit 40 according to the capacitance value, so that the control unit 40 performs the lifting operation on the position of the control unit 40 corresponding to the second adhesive layer 20 based on the control voltage value.

[0080] The control processor 90 designed in the embodiment is arranged in the display module, and the control processor 90 receives the capacitance values transmitted by the control units 40 through the signal lines L in real time. After receiving the capacitance values, the control processor 90 first performs judgment processing on the capacitance values. After judging that the capacitance values exceed the preset capacitance values, it is determined that the concave deformation at the positions of the control units 40 corresponding to the second adhesive layer 20 on the display panel causes the display panel to have the compression light leakage. At this time, the control processor 90 performs back calculation on the capacitance values based on formula 1 to obtain the electrode spacing on the capacitance sensor transmitting the capacitance values. After the deformation amount caused by the concave deformation on the display panel is inferred according to the electrode spacing, the control voltage value corresponding to the inferred deformation amount is extracted from the memory storing the control voltage values. Then, the control voltage value is returned to the corresponding control unit 40 through the line receiving the capacitance value, so that the control unit 40 can perform dynamic adjustment based on the control voltage value to offset the concave deformation existing in the second adhesive layer 20, thereby avoiding the compression light leakage caused by the tensile stress of the concave deformation on the display panel.

[0081] It should be noted that the deformation amount of the display panel corresponding to the electrode spacing and the control voltage value corresponding to the deformation amount are set by experiments in advance. The set deformation amount can correspond to the electrode spacing to the greatest extent. Similarly, the set control voltage value can offset the deformation amount to the greatest extent, so that the display panel tends to be flat, and the probability of the compression light leakage existing in the display panel during the display process caused by the deformation of the module frame is reduced or eliminated to the greatest extent.
