Description

Technical Field

[0001] The present invention relates to the technical field of display screens, and in particular to a touch display screen and an assembly method thereof. Background Art

[0002] Touch display screens are currently mainly divided into two types. One is that the touch screen and the display screen body (LCD screen) are completely attached without a gap between them. The other is that there is a gap between the touch screen and the display screen body. The size of the first type of touch display screen is greatly limited. With the continuous development of the industry, touch display screens are developing towards being light, thin, and large-sized. The second type of touch display screen has a large market application scenario. However, neither the front nor the back of the display screen body and the touch screen can be directly pre-pressed or supported by structural parts. Due to electrostatic adsorption and the self-gravity of the display screen body, both sides are prone to bending to varying degrees. There are fulcrums around the display screen body, and these fulcrums are more likely to cause the display screen body to bend. During the use of the display screen body, it is basically facing upwards, and the one-way use exacerbates the possibility of the display screen body bending and is extremely likely to cause reverse bending. When the gap between the display screen body and the touch (TouchPad, TP) screen is too small, it may cause electrostatic adsorption between the two, that is, positive bending, and the positive bending will form a cluster of watermarks. Whether it is reverse bending or positive bending, it will seriously affect the display effect and deteriorate the user experience.

[0003] For positive bending, currently, generally, the method of increasing the gap between the display screen body and the TP screen is adopted to ensure that the gap is greater than the deformation amount caused by the self-weight of the display screen body itself, so as to avoid or eliminate the problem of cluster of watermarks.

[0004] However, increasing the gap between the display screen body and the TP screen will bring the following disadvantages:

[0005] 1. The light loss will increase, not only the ambient light, but also the backlight of the display screen body, which affects the display effect, increases the energy consumption, and affects the battery life of the product;

[0006] 2. The overall thickness of the machine becomes thicker, which affects the user's hand feeling and user experience. Summary of the Invention

[0007] The present invention provides a touch display screen and an assembly method thereof to solve the technical problems of easy bending and inconvenient calibration of touch display screens in the prior art.

[0008] To solve the above technical problems, the present invention provides a touch display screen, which includes a touch screen, a display screen body, and a support plate stacked in sequence. A first sealed chamber is formed between the touch screen and the display screen body, and the first sealed chamber has a first air pressure. A second sealed chamber is formed between the display screen body and the support plate, and the second sealed chamber has a second air pressure. The first air pressure and the second air pressure can support the display screen body, and the first air pressure and the external air pressure can support the touch screen. By adjusting the first air pressure and the second air pressure, the supporting forces of the touch screen and the display screen body can be adjusted.

The first sealing structure is disposed between the touch screen and the display screen body, so that the touch screen, the first sealing structure, and the display screen body form the first sealed chamber.

[0010] The second sealing structure is disposed between the display screen body and the support plate, so that the display screen body, the second sealing structure, and the support plate form the second sealed chamber.

[0011] Optionally, the first sealing structure and the second sealing structure are each one or a combination of a sealing foam, glue, and double-sided tape.

[0012] Optionally, the sealing foam is annular.

[0013] Optionally, the first air pressure and the second air pressure are adjusted according to the following formula:

[0014] P2 = P1 + G / S, where P1 is the first air pressure, P2 is the second air pressure, G is the self-weight of the display screen body, and S is the contact area between the display screen body and the second sealed chamber.

[0015] The present invention also provides an assembly method for the above touch display screen, including:

[0016] Assembling the touch screen, the display screen body, and the support plate in the stacked order, so that the first sealed chamber is formed between the touch screen and the display screen body, and the second sealed chamber is formed between the display screen body and the support plate. The first sealed chamber has a first air pressure, and the second sealed chamber has a second air pressure. The first air pressure and the second air pressure have the following relationship:

[0017] P2 = P1 + G / S, where P1 is the first air pressure, P2 is the second air pressure, G is the self-weight of the display screen body, and S is the contact area between the display screen body and the second sealed chamber.

[0018] Optionally, the supporting forces of the touch screen and the display body are adjusted by adjusting the first air pressure and the second air pressure.

[0019] Optionally, assembling the touch screen, the display body and the support plate in the order of stacking includes:

[0020] Under the air pressure environment of the first air pressure, assembling the touch screen and the display body to form the first sealed chamber so that the air pressure in the first sealed chamber reaches the first air pressure;

[0021] Assembling the support plate and the display body to form the second sealed chamber;

[0032] Compared with the prior art, in the touch display screen of the present invention, there is a first air pressure between the touch screen and the display screen body, and a second air pressure between the display screen body and the support plate. The first air pressure and the second air pressure jointly support the display screen body. The first air pressure and the external air pressure can support the touch screen. The supporting forces for the touch screen and the display screen body are relatively balanced and stable, which can prevent the touch screen and the display screen body from bending. Especially when the touch display screen is an electronic product such as a display screen, the gap between the touch screen and the display screen body can be made very small, which can reduce the light loss, improve the battery life of the electronic product, and can make the display screen of the electronic product very thin, making the display screen beautiful and having good market competitiveness.

[0046] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0047] Please refer to Figure 1 and Figure 2, an embodiment of the present invention discloses a touch display screen 100, which includes a touch screen 10, a display screen body 20, and a support plate 30 stacked in sequence. A first sealed chamber 40 is formed between the touch screen 10 and the display screen body 20. The first sealed chamber 40 has a first air pressure. A second sealed chamber 50 is formed between the display screen body 20 and the support plate 30. The second sealed chamber 50 has a second air pressure. The first air pressure and the second air pressure can support the display screen body 20. The first air pressure and the external air pressure can support the touch screen 10. By adjusting the first air pressure and the second air pressure, the support force on the display screen body 20 can be adjusted.

[0048] In the touch display screen 100 of this embodiment, there is a first air pressure between the touch screen 10 and the display screen body 20, and a second air pressure between the display screen body 20 and the support plate 30. The first air pressure and the second air pressure jointly support the display screen body 20. The first air pressure and the external air pressure can support the touch screen 10. The support force on the touch screen 10 and the display screen body 20 is relatively balanced and stable, which can overcome the electrostatic adsorption between the touch screen 10 and the display screen body 20, can overcome the self-weight of the display screen body 20, can avoid the bending of the touch screen 10 and the display screen body 20, can make the gap between the touch screen 10 and the display screen body 20 very small, can reduce the light loss, improve the battery life of electronic products, can make the touch display screen 100 very thin, make the touch display screen 100 have aesthetic feeling, and have good market competitiveness.

[0049] Since the external air pressure is basically constant, by adjusting the first air pressure and the second air pressure, the support force on the touch screen 10 and the display screen body 20 can be adjusted. If the touch screen 10 or the display screen body 20 is bent, the touch screen 10 or the display screen body 20 can be corrected in time by adjusting the first air pressure and the second air pressure.

[0050] In one embodiment, the circuit of the display screen body 20 can be housed in the first sealed chamber 40, or can be housed in the second sealed chamber 50. Of course, it can also be housed on the support plate 30.

[0051] In one embodiment, the screen of the touch screen 10 can be made of glass material. In this embodiment, the first air pressure in the first sealed chamber 40 and the second air pressure in the second sealed chamber 50 can well support and fix it, can avoid the bending deformation of the touch screen 10 and the display screen body 20, and the acting force supporting each part of the touch screen 10 and the display screen body 20 is balanced and gentle, and will not damage the touch screen 10 and the display screen body 20.

[0052] In one embodiment, the touch display screen 100 further includes a first sealing structure 60 and a second sealing structure 70. The first sealing structure 60 is disposed between the touch screen 10 and the display screen body 20, so that the first sealing structure 60, the touch screen 10 and the display screen body 20 form the first sealed chamber 40; the second sealing structure 70 is disposed between the display screen body 20 and the support plate 30, so that the second sealing structure 70, the display screen body 20 and the support plate 30 form the second sealed chamber 50. The first sealing structure 60 and the second sealing structure 70 are respectively one or more combinations of a sealing foam, glue, and double-sided tape. In a specific embodiment, the first sealing structure 60 and the second sealing structure 70 are respectively sealing foams. A sealing foam is used for sealing between the touch screen 10 and the display screen body 20, and a sealing foam can also be used for sealing between the display screen body 20 and the support plate 30. The sealing effect is good, and the sealing foam has a certain buffering effect, and can form a flexible connection with the touch screen 10, the display screen body 20, and the support plate 30, avoiding damage to the touch screen 10, the display screen body 20, and the support plate 30. Preferably, in one embodiment, the sealing foam is annular, and the annular sealing foam is directly sealed between the touch screen 10 and the display screen body 20, and between the display screen body 20 and the support plate 30. On the one hand, the sealing effect of the first sealed chamber 40 and the second sealed chamber 50 can be better, and on the other hand, it can also achieve balanced contact support for the touch screen 10, the display screen body 20, and the back edge, making the structure of the touch display screen 100 more stable and the connection more firm. Further, glue can be applied between the sealing foam and the touch screen 10, the display screen body 20, and the support plate 30, so as to further enhance the sealing and connection effects. Further still, the sealing foam is square annular, and the square annular sealing foam can adapt to the shapes of the touch screen and the display screen body.

[0053] It can be understood that, according to actual needs, in some other embodiments, the first sealing structure 60 and the second sealing structure 70 can be glue or double-sided tape. It is also possible that the first sealing structure 60 is glue and the second sealing structure 70 is double-sided tape; or, the first sealing structure 60 is double-sided tape and the second sealing structure 70 is glue. Or, the first sealing structure 60 and the second sealing structure 70 are a sealing frame, and glue and the like are respectively used for sealing at the joints of the sealing frame and the touch screen 10, the display screen body 20, and the support plate 30.

[0054] In one embodiment, the first air pressure and the second air pressure are adjusted according to the following formula:

[0055] P2 = P1 + G / S, where P1 is the first air pressure, P2 is the second air pressure, G is the self-weight of the display body 20, and S is the contact area between the display body 20 and the second sealed chamber 50. When P2 = P1 + G / S, the second air pressure can overcome the self-gravity of the display body 20 and also overcome the electrostatic adsorption between the touch screen 10 and the display body 20, avoiding the bending of the display body 20 due to its self-weight. Moreover, the forces acting on both sides of the display body 20 are balanced, so that a balanced supporting force can be generated on both sides of the display body 20, and finally the touch display screen 100 can be prevented from bending. Therefore, when adjusting the first air pressure and the second air pressure, the first air pressure should be adjusted first. After adjusting the first air pressure, the second air pressure is adjusted according to the first air pressure. Of course, there can be a certain error between the first air pressure and the second air pressure being equal, that is, P2 ≈ (P1 + G / S) is sufficient. Among them, P1 can take the external air pressure, and the first air pressure can be basically equal to the external air pressure. Under the bearing capacity of the support plate 30 and the touch screen 10, P1 can also be greater than the external air pressure.

[0056] Specifically, as Figure 1 shown, when the touch display screen 100 is placed horizontally, that is, the touch screen is placed facing up. Taking the size of the touch display screen 100 as 9.7 inches as an example, G / S = 0.135 * 9.8 / 0.153 * 0.207 = 41.8 Ma, then the value of the second air pressure is the value of the first air pressure plus 41.8 Ma. The supporting force generated by the second air pressure is sufficient to overcome the self-weight generated by the display body, thereby preventing the display body from deforming due to its self-weight, and the touch display screen 100 can be made extremely thin.

[0057] As Figure 2 shown, when the touch display screen 100 is placed vertically, that is, the display body and the touch screen are placed along the vertical direction. Due to the sealing effect of the sealing foam, the magnitudes of the first air pressure and the second air pressure are fixed. A certain pressure difference is allowed between the first air pressure and the second air pressure, and it will not affect the touch screen 10 and the display body 20. The first air pressure and the second air pressure can still generate a balanced support for the display body to prevent it from deforming.

[0058] As Figure 3 shown, in existing products, plate structures such as the display screen 101 are extremely prone to uneven stress and prone to phenomena such as bending.

[0059] As Figure 4 shown, the ideal plate structure such as the display screen 101 is flat. The touch display screen 100 in this embodiment can basically achieve this effect through the first air pressure and the second air pressure. Moreover, when the touch screen 10 or the display body 20 is bent, it can be adjusted in time, with convenient adjustment, simple structure, and low manufacturing and maintenance costs.

[0060] An embodiment of the present invention also discloses an assembling method for the above touch display screen 100, including:

[0061] Assemble the touch screen 10, the display screen body 20, and the support plate 30 in the order of stacking, so as to form the first sealing chamber 40 between the touch screen 10 and the display screen body 20, and form the second sealing chamber 50 between the display screen body 20 and the support plate 30. The first sealing chamber 40 has a first air pressure, the second sealing chamber 50 has a second air pressure, and the relationship between the first air pressure and the second air pressure is as follows:

[0062] P2 = P1 + G / S, where P1 is the first air pressure, P2 is the second air pressure, G is the self-weight of the display screen body 20, and S is the contact area between the display screen body 20 and the second sealing chamber 50.

[0063] In the assembling method of the touch display screen 100 in this embodiment, the first air pressure and the second air pressure jointly support the display screen body 20. The first air pressure and the external air pressure can support the touch screen 10. The supporting forces for the touch screen 10 and the display screen body 20 are relatively balanced and stable, can overcome the electrostatic adsorption between the touch screen 10 and the display screen body 20, can overcome the self-weight of the display screen body 20, can avoid bending of the touch screen 10 and the display screen body 20, can make the gap between the touch screen 10 and the display screen body 20 very small, can reduce light loss, improve the battery life of electronic products, can make the touch display screen 100 very thin, make the touch display screen 100 have aesthetic feeling, and have good market competitiveness.

[0064] In one embodiment, the supporting forces for the touch screen 10 and the display screen body 20 are adjusted by adjusting the first air pressure and the second air pressure. If the touch screen 10 or the display screen body 20 is bent, the touch screen 10 or the display screen body 20 is corrected in time by adjusting the first air pressure and the second air pressure.

[0065] Please refer to Figure 5 , in one embodiment, the assembling of the touch screen 10, the display screen body 20, and the support plate 30 in the order of stacking includes:

[0066] A1. Under the air pressure environment of the first air pressure, assemble the touch screen 10 and the display screen body 20 to form the first sealing chamber 40, so that the air pressure in the first sealing chamber 40 reaches the first air pressure;

[0067] A2. Then assemble the support plate 30 and the display screen body 20 to form the second sealing chamber 50;

[0068] A3. Adjust the air pressure in the second sealing chamber 50 to the second air pressure. The air pressure in the second sealing chamber 50 can be adjusted to the second air pressure by means of inflation or the like.

[0069] After the first sealing chamber 40 is assembled, before the second sealing chamber 50 is assembled, the air pressure in the second sealing chamber 50 is adjusted to the second air pressure by means of inflation or the like. Assembling directly under the air pressure environment of the first air pressure can improve the assembly efficiency and processing quality of the touch display screen 100. Specifically, if the first air pressure is taken as the external air pressure, during assembly, directly in the external environment, the touch screen 10, the display screen body 20 and the support plate 30 are assembled. However, in this case, the supporting force for the touch screen 10 and the support plate 30 is slightly insufficient. Therefore, in the actual assembly process, the first air pressure is taken as a value slightly greater than the external air pressure. Keep the air pressure at the first air pressure in a closed environment, and then assemble the touch display screen 100 in this closed environment, which not only ensures the assembly efficiency but also ensures the product quality.

[0070] Please refer to Figure 6 , in an embodiment, the assembling of the touch screen 10, the display screen body 20 and the support plate 30 in the sequentially stacked order includes:

[0071] B1. After the touch screen 10, the display screen body 20 and the support plate 30 are assembled in the sequentially stacked order, the first sealing chamber 40 and the second sealing chamber 50 are respectively formed;

[0072] B2. Inflate the first sealing chamber 40 to make the air pressure in the first sealing chamber 40 reach the first air pressure,

[0073] B3. Inflate the second sealing chamber 50 to make the air pressure in the second sealing chamber 50 reach the second air pressure. After the touch screen 10, the display screen body 20 and the support plate 30 are assembled and sealed, inflation holes are respectively opened on the first sealing chamber 40 and the second sealing chamber 50, and the first sealing chamber 40 and the second sealing chamber 50 are respectively inflated. After inflation is completed, the inflation holes are then sealed. This assembly method has less dependence on the processing environment.

[0074] In an embodiment, the assembling of the touch screen 10, the display screen body 20 and the support plate 30 in the sequentially stacked order includes:

[0075] C1. When the touch screen 10, the display screen body 20 and the support plate 30 are assembled in the sequentially stacked order, a first chemical reaction pack is placed between the touch screen 10 and the display screen body 20, and the first sealing chamber 40 is formed between the touch screen 10 and the display screen body 20;

[0076] C2. The air pressure in the first sealed chamber 40 reaches the first air pressure through the first chemical reaction package;

[0077] C3. Place a second chemical reaction package between the display screen body 20 and the support plate 30 to form the second sealed chamber 50 between the display screen body 20 and the support plate 30;

[0078] C4. The air pressure in the second sealed chamber 50 reaches the second air pressure through the second chemical reaction package.

[0079] Among them, the amount of gas generated by the first chemical reaction package and the second chemical reaction package needs to be calculated according to P2 = P1 + G / S. Drugs that can generate gas can be placed in the first chemical reaction package and the second chemical reaction package. Before putting them in, the drugs are mixed and the chemical reaction starts. When the first sealed chamber 40 and the second sealed chamber 50 are completely closed, gas can be generated, so that the air pressure in the first sealed chamber 40 is the first air pressure and the air pressure in the second sealed chamber 50 is the second air pressure. This method has good airtightness and does not require an air inlet hole. After assembly, just wait for enough time to complete the assembly process, and it has less dependence on the assembly environment.

[0080] The touch display screen 100 and its assembly method of this embodiment can innovate the design concept of the use of display screens in the industry, scientifically and quantitatively achieve air pressure sealing balance for the display screen, fundamentally ensure that the display screen does not deform, and the display effect is better than the current one. Moreover, absolute sealing brings absolute dust-free display, which further ensures the display effect of the display screen. In addition, the requirements for the assembly space, the reliability of assembly and the product yield are guaranteed, and the installation is simple.

[0081] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; under the idea of the present invention, the technical features between the above embodiments or different embodiments can also be combined, and the steps can be implemented in any order, and there are many other variations in different aspects of the present invention as described above. For the sake of brevity, they are not provided in detail; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
