The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

A protective layer, a display panel, and an electronic apparatus according to embodiments of the present invention are described below with reference to fig. 1 to 3.

As shown in fig. 1 and 2, the protective layer 10 according to the embodiment of the present invention includes a first protective segment 100, a second protective segment 102, and a bending segment 104. The first and second guard segments 100 and 102 are connected by a bend segment 104. Specifically, one end of the bending section 104 is connected to the first protection section 100, and the other end of the bending section 104 is connected to the second protection section 102. The first guard section 100 comprises a first rigid light transmissive body, such as glass. The second protective segment 102 also includes a first rigid light transmissive body, such as glass. Further, the bending section 104 includes a flexible light-transmitting body 106 and a second rigid light-transmitting body 108, the second rigid light-transmitting body may be glass, and the flexible light-transmitting body may be a chinese balm.

It can be understood that the first rigid light-transmitting body and the second rigid light-transmitting body are both made of glass, and the glass is made of rigid light-transmitting materials. The glass has better strength and hardness, can form protection to the screen of electronic equipment, avoids the screen to be damaged. For example, for an electronic device such as a mobile phone, a touch screen is generally used nowadays, and a user operates the mobile phone by sliding a finger on the screen. The user's fingers are inevitably accompanied by some fine impurities, even small grits that are not perceptible to the naked eye. Still other users prefer to leave a sharp nail. When the substance such as the gravel, the fingernail and the like is scratched on the screen by the finger of the user, the substance such as the gravel, the fingernail and the like is difficult to scratch on the protective layer 10 due to the strength and the hardness of the glass, so that the screen is protected, and the damage of the screen is reduced.

In the bending section 104, because the requirement of folding the screen needs to be satisfied, a flexible light-transmitting material is generally adopted in the related art, so that the strength of the screen divided by the bending section 104 is relatively low. In the present embodiment, the bend 104 includes a second rigid optically transparent body 108 and a flexible optically transparent body 106. The second rigid light-transmitting body 108 is glass, the flexible light-transmitting body 106 is a chinese balm, and the chinese balm of the two is a flexible material, while the glass is a rigid material. At the bending section 104, through the setting of glass, the shortcoming that flexible material intensity is on the low side has been remedied, when keeping bending section 104 bending property, has promoted bending section 104's intensity again, has reduced the phenomenon that folding screen is damaged at bending section 104 position. Meanwhile, by arranging the second rigid light-transmitting body 108, the overall touch feeling of a user when the user uses the mobile phone can be improved, the user does not feel that the screen is softened at once suddenly when touching the bending section 104, and the comfort of the user when using the mobile phone is also improved.

The first rigid light transmitting body comprises crystal in addition to glass. That is, the first protective section 100 and the second protective section 102 may be made of crystal instead of glass, and when both are made of glass and crystal, they are physically combined, but not chemically fused.

In some embodiments, the first protective segment 100 comprises glass and the second protective segment 102 comprises crystal.

In other embodiments, the first rigid light-transmitting body of the first shielding section 100 comprises two materials, i.e., the first rigid light-transmitting body of the first shielding section 100 is made of two materials, i.e., glass and crystal, which are physically combined and chemically non-reacted. The first rigid light-transmitting body of the second guard segment 102 comprises only crystal. Alternatively, the first rigid light-transmitting bodies of the first and second protective sections 100 and 102 may both comprise glass and crystal.

Further, the bending section 104 includes glass and Chinese balm, or includes crystal and Chinese balm. Alternatively, the bending section 104 includes three materials, i.e., the second rigid light-transmitting body 108 includes two materials, i.e., glass and crystal, and the flexible light-transmitting body 106 includes Chinese perfume.

The flexible light-transmitting body 106 may include one or more of Canada balsam, fir resin, neutral resin, and synthetic resin, in addition to Chinese balsam. That is to say, the flexible light-transmitting body 106 of the bending section 104 may only include a chinese aromatic colloid, may also include a chinese aromatic colloid and a synthetic resin body, or include a combination of the chinese aromatic colloid, the neutral resin body, and the synthetic resin body, so that different flexible light-transmitting bodies 106 are adopted according to different electronic devices, thereby increasing the application range of the bending section 104.

It should be noted that when the flexible light transmissive body 106 comprises a plurality of different material bodies, they are merely combined, and merely physically or physically combined, and do not chemically react or fuse.

Specifically, in some embodiments, the bend 104 includes glass, chinese gum, and neutral resin. In other embodiments, the bend 104 includes crystal, glass, neutral resin, fir resin gel, and synthetic resin.

Further, in order to achieve the bending performance and the protection of the bending section 104 and to be uniform at each position, the second rigid light-transmitting bodies 108 and the flexible light-transmitting bodies 106 of the bending section 104 are alternately arranged. Specifically, for example, when the second rigid light-transmitting body 108 is made of glass and the bending section 104 includes glass and Chinese balm, the glass and the Chinese balm are alternately disposed, so that the bending section 104 has better bending performance and strength at various positions.

In still other embodiments, the bending section 104 includes glass, crystal, chinese balsam and synthetic resin, and the glass and the crystal, and the crystal are spaced from each other. In these spaces, either chinese balsam or synthetic resin is filled, or both chinese balsam and synthetic resin are filled in the same space.

As shown in fig. 2, in some implementations, the second rigid light-transmitting body 108 of the bend 104 includes: a base 1040 and a plurality of walls 1042. A plurality of walls 1042 are disposed on the base 1040. And a flexible light-transmitting body 106 is arranged between the adjacent walls 1042.

The second rigid light-transmitting body 108 is described as glass. The glass of the bend segment 104 includes a base 1040 and a plurality of walls 1042. By providing the substrate 1040, substantial support can be provided to the wall 1042, while also providing substantial support to the flexible light transmissive body 106. Due to the wall 1042, the thickness of the base 1040 is naturally reduced to keep the thicknesses of the first and second guard sections 100, 102 of the bending section 104 equal. The thinned substrate 1040 allows the rigid glass to bend somewhat and drive the other portions of the bend segment 104 to bend together, protecting the folded screen. Furthermore, the glass wall 1042 can resist the extrusion of the external force on the bending section 104 and protect the screen of the electronic device, thereby reducing the damage phenomenon of the screen, and meanwhile, when the user uses a finger to slide across the bending section 104, the user can feel better due to the hardness of the wall, and the use comfort of the folding screen is improved. The walls 1042 are arranged at intervals, which is beneficial to filling the flexible light-transmitting bodies 106 between the walls 1042, thereby achieving the purpose of alternately arranging the second rigid light-transmitting bodies 108 and the flexible light-transmitting bodies 106.

In some embodiments, the thickness of base 1040 is less than the thickness of first guard segment 100 and/or the thickness of second guard segment 102, which may reduce the strength of base 1040, allowing base 1040 to flex. Meanwhile, a space can be provided for the wall 1042, which is beneficial to ensuring that the total thickness of the wall 1042 after the substrate 1040 is added to the wall 1042 does not exceed the thickness of the first protection section 100 and/or the second protection section 102, so that the surface of the protection layer 10 is entirely smooth, the situation of sudden increase or decrease is avoided, and the comfort of a user using the electronic device is improved.

In some embodiments, the base 1040 is connected at both ends to the first guard segment 100 and the second guard segment 102, respectively. The connection mode can be bonding, welding or integral molding.

The base 1040, the first protective segment 100 and the second protective segment 102 are rigid light-transmitting bodies and can be made of the same material, so that the base and the first protective segment can be connected by welding or integral molding besides bonding.

The base 1040 is connected with the first protection segment 100 and the second protection segment 102, so that the bending segment 104, the first protection segment 100 and the second protection segment 102 can form a whole, the folding screen can be integrally protected, and the occurrence of a protection dead angle can be avoided.

Further, the base 1040 and the wall 1042 are integrally formed, which is beneficial to increasing the strength of the bending section 104, and is convenient for production and improves the production efficiency.

Optionally, a plurality of walls 1042 are provided on both sides of the base 1040, such that the base 1040 is generally centered in the bend 104. The substrate 1040 is substantially located in the middle of the bending section 104, so that the stress on both sides of the substrate 1040 is uniform, which is beneficial to improving the working stability of the substrate 1040 and reducing the local stress concentration on the substrate 1040. In addition, the base 1040 is provided with a plurality of walls 1042 on both sides, that is, both sides of the protection layer 10 have the same strength and performance. Therefore, when the protective layer 10 is covered on the screen, any surface of the protective layer 10 is connected with the screen, the protection function of the protective layer 10 can be ensured, and in the production process, the working surface of the protective layer 10 does not need to be checked, so that production is free from errors, and the production efficiency is high.

In some implementations, the walls 1042 are evenly distributed over the base 1040. By adopting the uniformly distributed structure, the bending section 104 is uniformly stressed, and the design and the production are relatively convenient. It is understood that the walls 1042 are uniformly distributed on the substrate 1040, which means that not only the intervals between the walls 1042 are equal, but also the thickness and height of the walls 1042 are equal. It should be noted that the height of the wall 1042 is relative to the base 1040, i.e., the distance from the side of the wall 1042 away from the base 1040 to the base 1040. The thickness of the wall 1042 refers to the distance between two sides of the wall 1042.

In other embodiments, the walls 1042 are not uniformly distributed on the base 1040, but gradually become thinner from side to side, or gradually become denser from middle to side. Specifically, the distance between the walls 1042 increases along the first protective segment 100 and along the second protective segment 102 toward the bend segment 104.

By adopting the gradual distribution mode, the walls 1042 at the two sides are dense, and the wall 1042 at the middle is sparse, so that more flexible light-transmitting bodies 106 can be filled in the part of the bending section 104 close to the middle. As shown in fig. 3, it can be understood that the middle of the bending segment 104 is the portion with the smallest bending radius and the portion with the largest stress and deformation. The sparse wall 1042 is arranged in the middle part, and more flexible light-transmitting bodies 106 are filled, so that the flexibility of the flexible light-transmitting bodies 106 can be utilized to adapt to the stress and deformation of the middle position, the bending smoothness of the bending section 104 is improved, and the bending reset is realized. And the flexible light-transmitting body 106 at the middle position is increased, which is also beneficial to reducing the crease of the bending section 104.

Optionally, to increase the bending performance of the bending section 104, more flexible light-transmitting bodies 106 are filled in the middle of the bending section 104, and this is not limited to increasing the space between the walls 1042. In other embodiments, the wall 1042 has a height that decreases with respect to the base 1040 in a direction along the first guard segment 100 and along the second guard segment 102 toward the bend segment 104. It is understood that the height of the wall 1042 near the middle position is lower than the height of the walls 1042 at the two side positions, and more flexible light-transmitting bodies 106 can be filled in the middle.

In still other embodiments, the walls 1042 do not decrease in height, but each wall 1042 has a decreasing cross-sectional area along the base 1040 in a direction away from the base 1040. Therefore, the height of the wall 1042 can be ensured to be unchanged, and the purpose of filling more flexible light-transmitting bodies 106 in the middle position can be achieved.

In still other embodiments, the wall 1042 has a constant height, but the wall 1042 has a decreasing thickness from side to side. That is, the thickness of the wall 1042 is thinner the closer to the middle of the bend 104. Thus, by reducing the thickness of the walls 1042, the distance between adjacent walls 1042 can be increased, and more flexible light-transmitting bodies 106 can be filled.

It is understood that in some other specific applications, the distance between the two sides of the wall 1042 is gradually increased toward the middle, and the thickness or height of the wall 1042 is gradually decreased at the same time, so as to increase the flexible light-transmitting body 106.

Because the first protection segment 100 and the second protection segment 102 cover a larger area of the screen and do not need to be bent, the strength of the first protection segment 100 and the second protection segment 102 can be further improved. In addition to the first protective segment 100 and the second protective segment 102 having a greater thickness than the substrate 1040, the first protective segment 100 and the second protective segment 102 may be made of tempered glass. The first protective section 100 and the second protective section 102 are made of toughened glass, so that the strength of the protective layer 10 can be greatly improved without increasing the thickness of the protective layer, the protective performance of the protective layer 10 can be further improved, and the damage to the screen can be reduced.

In some embodiments, the thickness of the first guard segment 100 and/or the second guard segment 102 is greater than or equal to 100 micrometers and less than or equal to 500 micrometers. For example, any of the following thicknesses: 100 microns, 120 microns, 160 microns, 200 microns, 240 microns, 300 microns, 360 microns, 400 microns. The thicknesses of the first protection section 100 and the second protection section 102 are set at the micron level, so that the screen can be protected to a certain extent, and the problem that the electronic equipment is inconvenient to use due to excessive increase of the weight and the volume of the electronic equipment caused by excessive thickness can be avoided.

The first protective segment 100 is a uniform layer of protective glass. The bending section 104 is a folding area using a double-sided glass wall + glue filling (i.e., the wall body 1042+ the flexible transparent body 106) manner, so as to improve the bending performance of the flexible display module 200 in the bending area. The second protective segment 102 is a uniform layer of protective glass. The glass thickness of the protection area for the folding plane area, i.e. the first protection segment 100 and the second protection segment 102, can be designed to be 100 micrometers to 500 micrometers to protect the flexible display module 200. For the folding area, that is, the bending section 104, a glass wall and glue filling manner is adopted, so that the mobile phone can be folded conveniently.

In addition, the strength of the flexible glass can be further improved through chemistry, so that the flexible glass has high hardness and high strength, has a certain impact resistance and protects a glass layer, and can be unfolded and folded together with the flexible display module 200 so as to achieve the effect of folding the mobile phone.

The specific embodiment of the invention is as follows:

The bending section 104 is a bending region, and has a main function of bending performance and good strength so as to satisfy the protection of the flexible display module 200, so that the bending section 104 adopts a double-sided glass wall and glue pouring mode. The second protective segment 102 functions in the same manner as the first protective segment 100, so the same design is used, and the glass thickness design refers to 100-500 microns of tempered glass. The specific structure is shown in fig. 1 and fig. 2.
