Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of display screens, and in particular to a display screen and an electronic device. Background Art

[0002] There are many kinds of electronic devices at present. Taking mobile terminals as an example, there are straight screens, flexible screens, folding screens and other types of devices. The straight screens all have a glass layer as a protective layer, so they are strong and will not be easily damaged by users. However, flexible screens and folding screens are made of flexible materials, so they are easy to be scratched or even damaged by users' sliding, touching and other uses. At this time, the entire screen needs to be replaced, which not only affects the user's use, but also has a high repair cost, which has a bad impact on the user's experience. In other words, whether it is a flexible screen or a rigid screen, if the surface is covered with a non-glass flexible cover, the surface is not slip-resistant and will easily be scratched. Summary of the invention

[0014] In some embodiments, the target layer is a layer structure formed by a first film cavity that mixes and wraps the first material and a second film cavity that mixes and wraps the second material. The target layer meets the light transmittance requirement and can bend as the display body bends.

[0015] In some embodiments, the target layer includes a dielectric layer, and the first membrane cavity encapsulating the first material and the second membrane cavity encapsulating the second material are mixed in the dielectric layer based on a specified ratio, and no chemical reaction occurs between the preparation materials of the first membrane cavity and the second membrane cavity and the dielectric layer material, the first material, and the second material, respectively.

[0016] In some embodiments, when a gap appears between the first portion of the target layer in the second state and the second portion of the target layer in the second state, at least the first membrane cavity wrapping the first material and the second membrane cavity wrapping the second material corresponding to the gap are ruptured, releasing the first material to react with the second material to generate the reaction product.

[0018] In some embodiments, the first material includes a resin material having a resin group, and the second material includes an amine material having an amine group.

[0038] This specification may use the phrases "in one embodiment," "in another embodiment," "in a further embodiment," or "in other embodiments," all of which may refer to one or more of the same or different embodiments according to the present disclosure.

[0039] Below, embodiments of the present application are described in detail with reference to the accompanying drawings.

[0040] like Figure 1 , Figure 2 and Figure 3 As shown, the embodiment of the present application provides a display screen, including a target layer 1,

[0041] A display body 2, wherein the target layer 1 covers the surface of the display body 2, and if the target layer 1 changes from a first state to a second state, the first material 5 of the target layer 1 reacts with the second material 6 of the target layer 1;

[0042] If the first material 5 of the target layer 1 reacts with the second material 6 of the target layer 1, so that the target layer 1 changes from the second state to the third state;

[0043] The first state is different from the second state, the second state is different from the third state, and the first state is similar to the third state.

[0044] That is to say, whether the display body is a flexible screen or a rigid screen, if the surface is covered with a non-glass flexible cover plate, the target layer can be a layer of material included in the non-glass flexible cover plate. In another embodiment, the target layer can also be a layer of material covered on the surface of the non-glass flexible cover plate. In another embodiment, the target layer can also be a flexible cover plate that replaces the non-glass.

[0045] The display screen in this embodiment can be applied to any electronic device, and the display body 2 can be a rigid screen or a flexible screen, without specific limitation. The target layer 1 is laid on a side of the display body 2 for displaying data, such as the screen surface, and can be directly touched by the user's fingers. The target layer 1 contains a first material 5 and a second material 6, and the first material 5 and the second material 6 present different material states when the target layer 1 is in different states. For example, the target layer 1 has three states, namely the first state, the second state and the third state, and the relationship between the three states is that the first state can directly lead to the formation of the second state, and the second state can be transformed into the third state. The state is mainly manifested as the physical state of the target layer 1, wherein the first state is different from the second state, and the third state is similar to the first state, or can also be the same, that is, the third state has a high degree of similarity with the first state. When the target layer 1 is in the first state, the material states of the first material 5 and the second material 6 of the target layer 1 are relatively stable, and the two are independent of each other. When the target layer 1 changes from the first state to the second state, the material states of the first material 5 and the second material 6 are no longer stable, and a chemical reaction occurs between the two materials, so that the target layer 1 in the second state gradually changes to the third state.

[0046] Of course, the target layer 1 may also include a third material, a fourth material, etc., or the first material 5 and the second material 6 are mixed materials, that is, the first material 5 may be composed of multiple materials, and the second material 6 may also be composed of multiple materials, which are not unique. For example, each material is a single material and there are multiple materials in the target layer 1. Similarly, when the target layer 1 is in the first state, the states of the various materials are stable and independent of each other in the target layer 1. However, when the target layer 1 changes from the first state to the second state, the various materials are no longer stable and will cooperate with each other to undergo chemical reactions, so that the target layer 1 in the second state changes to the third state until the change is completed.

[0047] Taking the case where the change in the state of the target layer 1 is caused by the damage of the layer structure as an example, when the target layer 1 is in a state of complete structure, the various materials in the target layer 1 are relatively stable, each independent of the target layer 1, and have no chemical influence on each other. When the target layer 1 is damaged, such as scratches, fragmentation, etc., the state of the target layer 1 changes to a damaged state, that is, the second state. At this time, the various materials of the target layer 1 will cooperate with each other to undergo chemical reactions to change the current damaged state and fragmentation state of the target layer 1, such as repairing and filling the damaged and fragmented parts, so that the target layer 1 changes from the second state to the third state, until the target layer 1 is in the third state. The third state is at least similar to the state when the layer structure of the target layer 1 is complete, so that it can ensure that the target layer 1 can continue to protect the screen without additional repairs, and the user can continue to use the display screen without causing serious use impact on the user, thereby improving the user's experience of the display screen.

[0048] In one embodiment, the target layer 1 is provided with a first membrane cavity 3 wrapping the first material 5 and a second membrane cavity 4 wrapping the second material 6. Taking the first membrane cavity 3 wrapping the first material 5 to form a first capsule, and the second membrane cavity 4 including the second material 6 to form a second capsule as an example, a large number of first capsules and second capsules are arranged in the target layer 1 in this embodiment. Of course, if more materials such as a third material and a fourth material are also included, more membrane cavities such as a third membrane cavity and a fourth membrane cavity can be set to cooperate with the corresponding materials to form different capsules. It can also be that for two or more materials that do not react at all, they can be mixed in the same membrane cavity to form a capsule, while the materials that react are wrapped in other membrane cavities to form different capsules. In this embodiment, the target layer 1 is provided with only the first material 5 and the second material 6 as an example for explanation. The distribution ratio of the first capsule formed by the first material 5 and the first membrane cavity 3 and the second capsule formed by the second material 6 and the second membrane cavity 4 in the target layer 1 is not fixed, for example, 1:1, 2:1, etc., which needs to be determined in combination with the reaction requirements when the two materials undergo a chemical reaction. The overall structural shape and size of the first capsule and the second capsule may be the same or different. For example, when two materials undergo a chemical reaction, two portions of the first material 5 and one portion of the second material 6 are required. The size of the first membrane cavity 3 is set larger to accommodate two portions of the first material 5. At this time, the size of the first capsule is larger, while the size of the second capsule is smaller, and only one portion of the second material 6 needs to be accommodated. Alternatively, the reaction requirements can be met by increasing the configuration ratio of the first capsule.

[0049] In this embodiment, the first state of the target layer 1 is a structurally complete state, such as an intact and undamaged surface. This state is composed of a first membrane cavity 3 that wraps the first material 5 and a second membrane cavity 4 that wraps the second material 6, that is, it is formed by the cooperation of a first capsule and a second capsule that are structurally complete.

[0050] The second state of the target layer 1 is a state of incomplete structure, such as scratches and cracks on the surface, and a damaged state. This state is caused by the damage of the first capsule and the second capsule located at the damaged location, that is, the membrane cavity of the first capsule and the second capsule is scratched, and cracks and scratches appear, resulting in the target layer 1 being in the second state.

[0051] The third state of the target layer 1 is a state in which the structure is nearly intact and the damaged parts are repaired. When the first capsule and the second capsule are scratched, the first material 5 and the second material 6 inside are released. At this time, a chemical reaction will occur when the two materials come into contact. The generated reaction product 7 can fill and repair the damaged parts of the target layer 1, while the first capsule and the second capsule at the non-damaged parts of the target layer 1 are still in a structurally intact state. Therefore, the third state of the target layer 1 is composed of the first membrane cavity 3 wrapping the first material 5, the second membrane cavity 4 wrapping the second material 6, and the reaction product 7 of the first material 5 and the second material 6.

[0052] Specifically, since the target layer 1 is filled with a large number of first capsules and second capsules, the membrane cavities of the two capsules are attached to the layer wall of the target layer 1, or the membrane cavities of the capsules directly form the layer wall of the target layer 1. When the target layer 1 is damaged, that is, cracked, the target layer 1 is in the second state, and the target layer 1 in the second state is divided into two parts by the crack, namely the first part and the second part, and the gap between the two parts forms the crack, and the crack will inevitably extend to the membrane cavity of the capsule at the corresponding position, or the crack is formed by the rupture of the capsule membrane cavity, so the first capsule and the second capsule at the damaged position will be released due to the rupture of the membrane cavity, and then contact each other to produce a chemical reaction to obtain a reaction product 7, and the reaction product 7 is directly filled in the damaged part of the target layer 1, so the reaction product 7 of the first material 5 and the second material 6 will directly fill the gap between the first part of the target layer 1 in the second state and the second part of the target layer 1 in the second state, completing the repair of the gap. The repaired target layer 1 is in the third state.

[0053] Furthermore, the reaction product 7 of the first material 5 and the second material 6 can also fix the first part of the target layer 1 in the second state and the second part of the target layer 1 in the second state. That is, it can help fix the two parts of the target layer 1 to prevent them from shifting when the user uses the display screen, resulting in an increase in the damaged position or even damage to the repair area.

[0054] The degree of fixation is not limited and needs to be determined according to the amount of reaction product 7. For example, when the configuration ratio of the first capsule and the second capsule in the target layer 1 is relatively large, when the capsule at the damaged part ruptures, it may cause the adjacent capsules to rupture together, or when the amount of material contained in the capsule is large, that is, when the amount of reaction product 7 corresponding to the amount of material is greater than the amount of reaction product 7 required for the damage repair, when the capsule at the damaged part ruptures, an excess of the first material 5 and the second material 6 can be released. At this time, the reaction product 7 generated after the reaction of the first material 5 and the second material 6 can not only fill the damage, but also can simultaneously adhere the first part and the second part of the target layer 1 around the damaged part, thereby fixing the relative position of the first part and the second part of the target layer 1 as a whole to avoid its force displacement. Among them, the size of the adhesion area is determined by the amount of reaction product 7. The larger the adhesion area, the better the fixing effect.

[0055] Continue to combine Figure 1 and Figure 2 As shown, the target layer 1 in this embodiment is a layer structure formed by the first film cavity 3 that mixes and wraps the first material 5 and the second film cavity 4 that wraps the second material 6. The specific thickness is not limited. The target layer 1 meets the light transmittance requirement. At the same time, the first film cavity 3, the second film cavity 4, the first material 5, the second material 6, and the reaction product 7 also meet the light transmittance requirement, so that the content displayed on the screen of the display screen can be seen by the user through the target layer 1. In actual application, the target layer 1 can be a structural state that can transmit the content of the display screen without distinction to avoid affecting the display effect of the display screen.

[0056] When the display body 2 is a flexible body, the target layer 1 is in a structural state that can be bent along with the bending of the display body 2. That is, when selecting the first material 5, the second material 6, the first film cavity 3, the second film cavity 4 and other required materials for preparing the target layer 1, it is necessary to select a material that can support the target layer 1 to bend synchronously with the bending of the display body 2.

[0057] In another embodiment, the target layer 1 includes a dielectric layer, and the first film cavity 3 encapsulating the first material 5 and the second film cavity 4 encapsulating the second material 6 are mixed in the dielectric layer based on a specified ratio, that is, the target layer 1 is formed by a combination of dielectric material, first material 5, second material 6, first film cavity 3, and second film cavity 4, and the first capsule formed by the first material 5 and the first film cavity 3 and the second capsule formed by the second material 6 and the second film cavity 4 are distributed in the dielectric layer based on a specified ratio. The light transmittance of the dielectric layer meets the requirements and supports the target layer 1 to bend with the bending of the display body 2. There is no chemical reaction between the preparation materials of the first film cavity 3 and the second film cavity 4 and the dielectric layer material, the first material 5, and the second material 6, respectively, that is, the first film cavity 3 and the second film cavity 4 can be stably in the dielectric layer, and when the first material 5 and the second material 6 are released, the dielectric layer material will not participate in the chemical reaction between the first material 5 and the second material 6. In addition, when the first membrane cavity 3 and the second membrane cavity 4 are broken, they will not volatilize, the membrane cavity material is stable from beginning to end, and the membrane cavity only produces physical structural changes.

[0058] The dielectric layer material may be a material with a certain strength, that is, it has a certain pressure bearing capacity, or the first membrane cavity 3 and the second membrane cavity 4 may also be a material with a certain strength, and can also withstand a certain pressure, which is a pressure that exceeds the force when the user normally touches the display screen. For example, hardened particles may be added to the dielectric layer, or some hardened particles may be added to the membrane cavity material, so as to improve the damage resistance of the target layer 1 while ensuring that the display and bending are not affected.

[0059] Furthermore, in the medium layer, the first capsules and the second capsules can be arranged alternately and close to each other; or the first capsules and the second capsules can be arranged mixedly, and each of the second capsules is surrounded by at least one first capsule. When there are multiple capsules, that is, when different materials are filled in the multiple capsules, they can also be arranged in the above manner.

[0060] When the target layer 1 is subjected to a force exceeding its own tolerance, resulting in damage, such as cracks, the first film cavity 3 wrapped with the first material 5 and the second film cavity 4 wrapped with the second material 6 at the corresponding crack are broken, and after the first material 5 and the second material 6 are released, the specific reactants in the two materials will contact and react chemically to obtain a reaction product 7 for filling the crack. For example, the first material 5 has a first group, and the second material 6 has a second group. The first material 5 and the second material 6 generate the reaction product 7 through a free radical polymerization reaction initiated by the first group and the second group. The reaction product 7 includes a three-dimensional network structure, or may also be a structure of other structures. The reaction product 7 will gradually harden and solidify, and then stably and firmly fill the crack to achieve repair.

[0061] Specifically, in practical applications, the first material 5 can be selected as a resin material, or other materials having a resin group, and the second material 6 can be selected as an amine material, or other materials having an amine group. After the resin group and the amine group are combined, free radical polymerization will occur to generate a three-dimensional network structure. Of course, the first material 5 and the second material 6 can also be other materials that can meet the above effects, and the specific ones are not exclusive.

[0062] Another embodiment of the present application also provides an electronic device, including:

[0063] A display screen, wherein a surface of the display screen is covered with a target layer, and if the target layer changes from a first state to a second state, the first material of the target layer reacts with the second material of the target layer;

[0064] If the first material of the target layer reacts with the second material of the target layer, so that the target layer changes from the second state to the third state;

[0065] The first state is different from the second state, the second state is different from the third state, and the first state is similar to the third state.

[0066] In another embodiment, the difference from the previous electronic device embodiment is that the display screen is a deformable screen; the shell includes a first shell and a second shell, and the first shell and the second shell can move relative to each other, wherein the first shell and the second shell can move relative to each other to change the shape of the display screen; the first shell and the second shell are in a first relative position relationship, and the display screen is in a first shape; the first shell and the second shell are in a second relative position relationship, and the display screen is in a second shape, and the first shape of the display screen is different from the second shape of the display screen.

[0067] The electronic device may be, but is not limited to, a mobile phone, a tablet computer, a desktop display, etc. Taking the first state as an undamaged state of the display screen surface, the second state as a damaged state of the display screen surface, and the third state as a repaired state of the display screen surface as an example, by using the display screen of this embodiment, the display screen can be supported to have a self-repairing ability, and when cracks appear on the display screen surface, no human intervention is required, and the screen surface can be automatically repaired based on the released first material and second material, and no user intervention is required for repair, which provides convenience for users to use the display screen and electronic devices and improves the user experience of the display screen and electronic devices.
