With the foregoing drawings in mind, certain embodiments of the disclosure have been shown and described in more detail below. These drawings and written description are not intended to limit the scope of the disclosed concepts in any way, but rather to illustrate the concepts of the disclosure to those skilled in the art by reference to specific embodiments.

Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, the embodiments of the present disclosure will be described in further detail below with reference to the accompanying drawings.

With the progress of display technology, electronic products which can be pasted on human skin (skin), namely electronic skin, have come into play. Among them, a display device including a stretchable display (stretchable display) or a stretchable sensor and being capable of being stuck on the skin of a human body belongs to an application of electronic skin, which may also be referred to as a skin display application. The stretchable display may be referred to as the body of the electronic device in the electronic skin.

Wherein, the stretchable display may include a display panel, on which a paper-cut structure having an opening is generally disposed to provide a stretching amount by deformation of the shape of the opening; or the display panel can be arranged in a fold structure to achieve a deformation effect through three-dimensional change on the fold structure; alternatively, the display panel is of an elastic structure, i.e., made of an elastic material, so as to be stretched and deformed by the elastic material. Moreover, under the traction of the change of the muscle of the human body, the skin of the human body can be deformed in different degrees naturally, and the deformation can drive the stretchable display to generate a dynamic stretchable display effect.

However, it is tested that if the stretching amplitude is larger and/or the stretching time is longer, the stress on the stretchable display is uneven, the working stability of the stretchable display is affected, and the display effect is poor. The reliability of the existing electronic skin is poor, and the user requirements cannot be well met.

Thus, the disclosed embodiments provide a new electronic skin. The electronic skin adopts the viscose (adhesive) layers with different moduli, so that the stress generated by the deformation of the human skin can be fully released into the viscose layer with low modulus, and the influence of the stress on the electronic equipment body (such as the stretchable display recorded in the embodiment) is reduced, thereby ensuring that the working stability of the electronic equipment body can be better and the product reliability can be higher.

Fig. 1 is a schematic structural diagram of an electronic skin provided in an embodiment of the present disclosure. As shown in fig. 1, the electronic skin includes: the electronic equipment comprises an electronic equipment body 01, a plurality of sequentially stacked adhesive layers 02 located on one side of the electronic equipment body 01, and a protective film layer 03 located between at least two adjacent adhesive layers 02.

For example, referring to fig. 1, the shown e-skin includes two adhesive layers 02, and a protective film layer 03 disposed between the two adhesive layers 02. Figure 1 also schematically shows human skin.

The multilayer adhesive layer 02 can be used for adhering the electronic device body 01 to the skin of a human body. In the multilayer adhesive layer 02, at least two adhesive layers 02 have different moduli. For example, the moduli of the adhesive layers 02 may be different.

And in the multilayer adhesive layer 02, the modulus of the adhesive layer 02 far away from the electronic device body 01 is smaller than the modulus of the adhesive layer 02 near the electronic device body 01. That is, the modulus of the adhesive layer 02 on the side close to the human skin is smaller than the modulus of the adhesive layer 02 on the side away from the human skin. In other words, the modulus of the adhesive layer 02 directly adhered to the human skin may be small, referred to as a low modulus adhesive layer 02. The adhesive layer 02 directly adhered to the electronic device body 01 may have a large modulus, which is referred to as a high modulus adhesive layer 02.

Wherein, the modulus of the viscose layer 02 is as follows: after the adhesive layer 02 is cured, the ratio of stress to strain under a stress state, and the modulus can be regarded as an index for measuring the difficulty of the adhesive layer 02 in generating elastic deformation. The modulus of the adhesive layer 02 is inversely related to the elastic deformation of the adhesive layer 02 under a certain stress. That is, the greater the modulus of the adhesive layer 02 is, the greater the stress at which the adhesive layer 02 is elastically deformed to some extent, that is, the smaller the elastic deformation is generated by a certain stress. Conversely, the smaller the modulus of the adhesive layer 02 is, the smaller the stress of the adhesive layer 02 that generates a certain elastic deformation is, i.e., the larger the elastic deformation is generated under the action of a certain stress.

Based on this, the modulus of the viscose layer 02 close to one side of the human skin is smaller than the modulus of the viscose layer 02 far away from one side of the human skin, so that when the human skin deforms to generate stress, the elastic deformation of the viscose layer 02 close to one side of the human skin is larger than the elastic deformation of the viscose layer 02 far away from one side of the human skin. Namely, the stress is fully released on the low modulus adhesive layer 02 close to the human skin side, and the influence of the stress on the electronic device body 01 is reduced, so that the working stability of the electronic device body 01 is improved. In addition, the adhesive layer 02 near the electronic device body 01 can also be used for stabilizing the electronic device body 01.

Taking the structure shown in fig. 1 as an example, fig. 2 shows a top view of a protective film layer 03. As can be seen from fig. 1 and 2, the protective film 03 according to the embodiment of the disclosure may have a plurality of first through holes K1, and the first through holes K1 may also be referred to as openings penetrating through the protective film 03.

The protective film 03 can be used for effectively protecting the adjacent upper and lower films, and moisture generated by the skin of a human body can be discharged from the adhesive layer 02 through the first through holes K1. In addition, stress distribution can also be modified by the arrangement of the first through hole K1 on the protective film layer 03, so that the stress borne by the electronic equipment body 01 can be relatively uniform, and the working stability of the electronic equipment body 01 is further improved.

Alternatively, in the embodiment of the present disclosure, the plurality of first through holes K1 may be obtained by a patterning (patterning) process.

For example, a protective film may be provided, and then the protective film may be patterned by using a mask to form a plurality of first through holes K1 penetrating through the protective film, so as to obtain the protective film 03 having the first through holes K1.

To sum up, this disclosed embodiment provides an electron skin, and this electron skin is including the electronic equipment body and the multilayer viscose layer that stack gradually to and be located the protection film layer between the adjacent two-layer viscose layer, this viscose layer can paste the electronic equipment body on human skin. Because of keeping away from the modulus of the viscose layer of electronic equipment body (i.e. be close to human skin) one side and being less than the modulus of the viscose layer of being close to electronic equipment body (i.e. keep away from human skin) one side, and the protection film has a plurality of through-holes, so not only can fully release the stress that human skin deformation produced to the low modulus viscose layer of keeping away from electronic equipment body one side, can reach the purpose of decorating stress distribution through this through-hole moreover. Therefore, the stress borne by the electronic equipment body is smaller and more uniform, and the working stability of the electronic equipment body can be better.

Optionally, fig. 3 is a schematic structural diagram of another electronic skin provided in the embodiment of the present disclosure. As can be seen with reference to fig. 1 and 3, the electronic skin according to the embodiment of the present disclosure may include: two layers of adhesive 02.

Wherein, one layer of viscose layer 02 can be used for directly pasting with human skin, and another layer of viscose layer 02 can be directly pasted with electronic equipment body 01. That is, the electronic skin according to the embodiments of the present disclosure may be a double-layer adhesive design. And, on this basis, the e-skin may include a protective film 03 between the two adhesive layers 02.

In order to distinguish the two adhesive layers 02, the adhesive layer 02 directly adhered to the skin of the human body is denoted as 02(1) and the adhesive layer 02 directly adhered to the electronic device body 01 is denoted as 02(2) in fig. 3.

Optionally, with continued reference to fig. 3, in the two adhesive layers 02 according to the embodiment of the disclosure, the modulus of the adhesive layer 02 close to the electronic device body 01, i.e. the adhesive layer 02(2), may be 10⁸-10¹¹Pa (Pa) between. The adhesive layer 02 far from the electronic device body 01, i.e. the adhesive layer 02(1), has a modulus of 10³-10⁶Pa is between Pa.

Wherein the modulus of the adhesive layer 02(2) is 10⁸-10¹¹Pa may mean: the adhesive layer 02(2) may have a modulus of 10 or more⁸Pa is not more than 10¹¹Pa. Similarly, the modulus of the adhesive layer 02(1) is 10³-10⁶Pa may mean: the adhesive layer 02(1) may have a modulus of 10 or more³Pa is not more than 10⁶Pa。

It should be noted that the measuring frequency corresponding to the above modulus can be between 0.1 hertz (Hz) and 1 Hz. That is, the modulus may be in a range measured in a scene with a frequency of 0.1Hz or more and 1Hz or less. Here, the frequency may refer to a frequency of vibration generated to generate the deformation.

As described in the above embodiments, in the dual-layer adhesive design, the low-modulus adhesive layer 02(1) can be used for stress release, and the high-modulus adhesive layer 02(2) can be used for stabilizing the electronic device body 01.

Optionally, as can be seen with continued reference to fig. 3, the electronic device body 01 according to the embodiment of the present disclosure may include: a stretchable display. Accordingly, as described in the above embodiments, the application scenario of the electronic skin is a skin display application, and the electronic skin can be used to implement a display function. Furthermore, on the premise of improving the working stability of the stretchable display, the display effect of the stretchable display can be improved.

Of course, in some other embodiments, the electronic device body 01 may further include a stretchable sensor, i.e., a sensor circuit. Further, on the premise of improving the operation stability of the sensor circuit, the sensing result of the sensor circuit can be improved. For example, the sensor circuit may be a pressure sensor circuit, and accordingly, the electronic skin including the electronic device body 01 may be used to sense pressure applied to the skin of a human body.

The electronic device body 01 may be other stretchable electronic products that can be attached to the skin of a human body, and is not limited to the display or the sensor circuit described in the above embodiments.

Optionally, the stretchable display described in the embodiments of the present disclosure may include a display panel: an organic light-emitting diode (OLED) display panel, an active-matrix organic light-emitting diode (AMOLED) display or a liquid crystal display panel, and the like.

Optionally, the material of the adhesive layer 02 described in the embodiment of the present disclosure may include: a pressure sensitive adhesive material. Accordingly, as shown in fig. 3, the adhesive layer 02 may also be referred to as a pressure sensitive adhesive.

Optionally, the material of the protective film 03 described in the embodiment of the present disclosure includes: polyethylene terephthalate (PET). Accordingly, as shown in fig. 3, the protective film layer 03 having the first through hole K1 may also be referred to as a patterned PET material layer.

Fig. 4 is a schematic structural diagram of another electronic skin provided in the embodiments of the present disclosure. As shown in fig. 4, the electronic skin according to the embodiment of the present disclosure may further include: and the waterproof layer 04 is positioned between the protective film layer 03 and the adhesive layer 02. That is, the upper and lower sides of the protective film 03 may be provided with the corresponding water blocking layers 04, respectively.

The moisture barrier layer 04 can be used for reliably blocking moisture generated by the skin of the human body, and guiding the moisture to be arranged toward the side of the adhesive layer 02, so as to avoid the problem that the moisture diffuses upward and invades the electronic device body 01 (fig. 4 indicates a stretchable display), so as to cause damage to devices in the electronic device body 01. That is, the water blocking layer 04 can be provided to further effectively protect the electronic apparatus main body 01.

Optionally, because the protective film 03 is located between two adjacent adhesive layers 02, as shown in fig. 4, a water-blocking layer 04 may be respectively disposed between the protective film 03 and the two adhesive layers 02. That is, the e-skin may include two water-resistant layers 04 on the basis of including two adhesive layers 02 and one protective film layer 03.

One layer of the water-blocking layer 04 may be located between the protection film layer 03 and the adhesive layer 02(1) on the side far from the electronic device body 01, and the other layer of the water-blocking layer 04 may be located between the protection film layer 03 and the adhesive layer 02(2) on the side near to the electronic device body 01.

Of course, in some other embodiments, the water blocking layer 04 may be disposed between the protection film layer 03 and the adjacent adhesive layer 02. That is, the e-skin may include only one layer of the water-resistant layer 04.

Optionally, the material of the water blocking layer 04 described in the embodiment of the present disclosure may include: inorganic (inorganic) materials such as silicon nitride (SiN) and silicon oxide (SiO). That is, as shown in fig. 5, which is yet another kind of electronic skin, the water-resistant layer 04 may be an inorganic material layer.

To distinguish the two water-resistant layers 04, the water-resistant layer 04 on the side away from the electronic apparatus main body 01 is denoted as 04(1) in fig. 5, and the water-resistant layer 04 on the side close to the electronic apparatus main body 01 is denoted as 04 (2).

Alternatively, taking the structure shown in fig. 5 as an example, fig. 6 shows a top view of a water-blocking layer 04 (1). Referring to fig. 6, the water-blocking layer 04(1), i.e., the water-blocking layer 04(1) between the protective film 03 and the adhesive layer 02(1) on the side away from the electronic device body 01, may have a plurality of second through holes K2.

In combination with fig. 2, in the embodiment of the present disclosure, an orthographic projection of the plurality of second through holes K2 on the electronic device body 01 may overlap with an orthographic projection of the plurality of first through holes K1 on the electronic device body 01. Here, the overlapping may mean that the plurality of first through holes K1 and the plurality of second through holes K2 are overlapped in a one-to-one correspondence, and accordingly, the water blocking layer 04 may be considered to have the same number of second through holes K2 as the number of first through holes K1 of the protective film layer 03.

Of course, in some other embodiments, the overlapping may also mean that there is an overlap of the plurality of second through holes K2 and the plurality of first through holes K1.

Through setting up the water-blocking layer 04(1) of keeping away from electronic equipment body 01 one side still have second through-hole K2, can effectively reduce the stress that human skin deformation produced in the one side of keeping away from electronic equipment body 01 promptly, reach the purpose that further decorates stress distribution for electronic equipment body 01 is more even because of the stress that human skin deformation receives, thereby further improves electronic equipment body 01's job stabilization nature.

Alternatively, the plurality of second through holes K2 may be formed by patterning, as in the above-described manner of forming the first through hole K1.

For example, a water-blocking film may be provided, and then the water-blocking film is patterned by using a mask to form a plurality of second through holes K2 penetrating through the water-blocking film, so as to obtain the water-blocking layer 04 with the second through holes K2.

Optionally, on the basis that the plurality of first through holes K1 and the plurality of second through holes K2 are overlapped in a one-to-one correspondence manner, the plurality of first through holes K1 and the plurality of second through holes K2 may be formed simultaneously through one patterning process, thereby simplifying the operation and saving the cost.

Alternatively, the opening of the first through hole K1 and the opening of the second through hole K2 described in the embodiments of the present disclosure may each have at least one rounded corner.

For example, referring to fig. 2 and 6, it can be seen that the openings of the first through hole K1 and the second through hole K2 described in the embodiments of the present disclosure may each have a rectangular shape with four rounded corners.

Of course, in some other embodiments, the shape of the opening of the first through hole K1 and the opening of the second through hole K2 may also be circular or elliptical or other shapes with rounded corners.

The shape of the opening may be a shape of an orthogonal projection of the opening onto the electronic apparatus main body 01, or may be a shape of an orthogonal projection of the through hole (including the first through hole K1 and the second through hole K2) itself onto the electronic apparatus main body 01.

The opening through setting up first through-hole K1 and the opening of second through-hole K2 all have at least one fillet, can reach the purpose that further modifies stress distribution for electronic equipment body 01 is more even because of the stress that human skin deformation receives, thereby further improves electronic equipment body 01's job stabilization nature.

Optionally, in the embodiment of the present disclosure, a substrate may be further disposed between the electronic device body 01 and the adhesive layer 02 (e.g., the adhesive layer 02(2)) directly adhered to the electronic device body 01, so as to effectively protect the electronic device body 01. The substrate may be a stretchable flexible substrate.

Optionally, when leaving the factory, a release layer may be further disposed on a side of the adhesive layer 02 (e.g., the adhesive layer 02(1)) away from the electronic device body 01 for adhering to the skin of the human body, so as to protect the adhesiveness of the adhesive layer 02. After leaving the factory, the user can peel off the release layer to stick the rest part to his skin, such as the skin of his arm, via the adhesive layer 02. The electronic skin can be called a novel wearable device.

Optionally, in the embodiment of the present disclosure, the thickness of each film layer included in the electronic skin, such as the adhesive layer 02, the protective film layer 03, and the water blocking layer 04, may be greater than 0 micrometer (μm) and less than or equal to 100 μm. For example, it may be 50 μm. The whole thickness of the electronic skin is smaller, and the electronic skin is more convenient to wear.

As can be seen from the above description, the embodiments of the disclosure focus on the Module (MDL) structure design of the electronic skin. For example, the MDL design may include: (1) designing a plurality of adhesive layers 02; (2) the modulus of each adhesive layer 02 is designed to be different; (3) the design of the protective film layer 03 and the waterproof layer 04 between the two adjacent adhesive layers 02, the design that the protective film layer 03 and the waterproof layer 04 are provided with through holes, and the like. And matching materials (such as pressure sensitive adhesive materials, inorganic materials and PET materials) among the layers to achieve the purposes of relieving stress applied to the electronic equipment body 01 and enabling the stress on the electronic equipment body 01 to be more uniform. Therefore, the working stability of the electronic device body 01 is further improved, for example, the display quality of the stretchable display is improved, and the product reliability of the electronic skin is further improved.

By way of example, taking the structure shown in fig. 5 as an example, fig. 7 shows a schematic diagram of deformation of an electronic skin when subjected to stress according to an embodiment of the present disclosure. Referring to fig. 7, in the embodiment of the present disclosure, the stress generated by the deformation of the human skin is sufficiently released on the low modulus adhesive layer 02(1), and the elastic deformation of the adhesive layer 02(1) is relatively large. The stress may become smaller when reaching the high modulus adhesive layer 02(2), and the elastic deformation of the adhesive layer 02(2) is smaller. Finally, the stretchable display is stressed less and more uniformly. In fig. 7, the magnitude of elastic deformation is indicated by an arrow.

In addition, as described in the above embodiments, the electronic skin according to the embodiments of the present disclosure is an electronic product that can be attached to the skin of a human body through an adhesive layer.
