Description

Flexible screen and electronic equipment

Technical Field

The application relates to the technical field of electronics, especially, relate to a flexible screen and electronic equipment.

Background

With the increasing development of electronic device technology, users have increasingly high demands for electronic devices having large sizes and being easy to carry, and therefore, electronic devices having foldable flexible screens are receiving wide attention. When the foldable flexible screen is assembled with a housing of an electronic device, in order to ensure that the foldable flexible screen can be switched between a folded state and an unfolded state, a folding deformation area of the flexible screen is not fixedly connected with the housing. When the folding flexible screen is folded, two possible motion states of outward convex folding and inward concave folding can occur in the folding deformation area. For an inwardly folded foldable flexible screen (i.e. two display surfaces of the flexible screen can be folded relatively and are contained between the folding shells), the outwardly protruding folding motion state will hinder the flexible screen from being folded normally inwards, and even damage the flexible screen.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

In order that the above objects, features and advantages of the present application can be more clearly understood, a detailed description of the present application will be given below with reference to the accompanying drawings and detailed description. In addition, the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth to provide a thorough understanding of the present application, and the described embodiments are merely a subset of the embodiments of the present application, rather than all embodiments. All other embodiments obtained by a person of ordinary skill in the art without any inventive work based on the embodiments in the present application are within the scope of protection of the present application.

Referring to fig. 1, an electronic device 100 is provided in an embodiment of the present disclosure. The electronic device 100 can achieve the effects of folding and unfolding. The electronic device 100 may be a tablet computer, a mobile phone, a camera, a personal computer, a notebook computer, a vehicle-mounted device, a wearable device, or other intelligent devices. For convenience of description, the electronic device 100 is defined with reference to the first viewing angle, the width direction of the electronic device 100 is defined as the X direction, the length direction of the electronic device 100 is defined as the Y direction, and the thickness direction of the electronic device 100 is defined as the Z direction.

As shown in fig. 1, the electronic device 100 includes a housing 2 and a flexible screen 4. A flexible screen 4 is mounted on the housing 2. It is understood that the flexible screen 4 may be an organic electroluminescent flexible screen, or may be a liquid crystal flexible screen. The flexible screen 4 is used for displaying electronic images.

Referring to fig. 2, the present embodiment provides a flexible screen 4. The flexible screen 4 includes a body portion 40 and a projection 50 which are integrally formed. It will be appreciated that the protrusion 50 is directly formed on the body portion 40 during the manufacturing process of the flexible screen 4, i.e. the protrusion 50 is not required to be fixed on the flexible screen 4 by an adhesive or a fastener, thereby ensuring the integrity and simplicity of the flexible screen 4. Optionally, the flexible screen 4 includes a flexible substrate, an array substrate, a color film substrate, and a cover plate. Typically by forming the flexible screen 4 on transparent glass. The flexible screen 4 is then removed from the transparent glass. Therefore, the recess is formed in the transparent glass, and the transparent material is applied to the transparent glass so that the recess is covered with the transparent material. At this time, the transparent glass is formed with a flexible substrate having the convex portion 50.

As shown in fig. 2, the main body 40 includes a first fixing area 41, a folding area 42 and a second fixing area 43. The fold region 42 is connected between the first fastening region 41 and the second fastening region 43. The folding zone 42 is capable of being deformed so as to fold or unfold the first fastening zone 41 against said second fastening zone 43. The convex portion 50 is provided to protrude from the non-display side of the folding region 42. It will be appreciated that the flexible screen 4 comprises a display surface 401 and a non-display surface 402, which are arranged opposite each other. The display surface 401 is used to display electronic images, i.e., the user can view the images through the display surface. The display surface 401 is located partly in the first fastening area 41, partly in the second fastening area 43 and partly in the folding area 42. The non-display face 402 is the face of the flexible screen 4 facing the housing 2. A portion of the non-display surface 402 is located at the folding area 42. The convex portion 50 is located on the non-display surface 402 of the folding area 42.

In the present embodiment, the flexible panel 4 is provided with the main body portion 40 and the protruding portion 50 which are integrally formed, and the protruding portion 50 is protruded on the non-display side of the folding area 42 of the main body portion 40, so as to increase the stress of the folding area 42 of the flexible panel 4, so that the display surface of the first fixing area 41 can be close to the display surface of the second fixing area 43 when the folding area 42 is bent, that is, the display surface of the first fixing area 41 does not move in a direction away from the display surface of the second fixing area 43 when the folding area 42 is bent.

In the present embodiment, as shown in fig. 1, the housing 2 includes a first portion 1 and a second portion 3 that can be folded or unfolded with respect to each other. The first fastening area 41 is attached to the first part 1 and the second fastening area 43 is attached to the second part 3. Alternatively, the first fastening region 41 may be attached to the first fastening region 41 by glue or fasteners. The second fastening section 43 may be attached to the second part 3 by means of glue or fasteners. In addition, the convex portion 50 is protruded from a side of the folding region 42 close to the housing 2.

Wherein the flexible screen 4 is located inside the housing 2 when the first part 1 is folded against the second part 3, as shown in fig. 3. It will be appreciated that when the housing 2 comprises the first, second and

third housings

10, 20, 30 of fig. 3, the folding of the first part 1 relative to the second part 3 means that the first housing 10 rotates relative to the third housing 30, and the second housing 20 rotates relative to the third housing 30, so that the first housing 10 is adjacent to the second housing 20, and the flexible screen 4 is located between the first housing 10 and the third housing 30.

It will be appreciated that when the first portion 1 is folded relative to the second portion 3, there are two folding conditions for the flexible screen 4. One is that the flexible screen 4 is folded towards the direction close to the housing 2. The other is that the flexible screen 4 is folded away from the housing 2. If the flexible screen 4 is folded in a direction close to the housing 2, the flexible screen 4 is normally folded. If the flexible screen 4 is folded away from the housing 2, the flexible screen 4 may be arched away from the housing 2, which is not favorable for the use of the electronic device 100. At this time, the convex portion 50 is protruded at a side of the folding area 42 close to the housing 2, so as to increase the internal stress of the folding area 42, and further, when the first portion 1 is folded relative to the second portion 3, the convex portion 50 prevents the flexible screen 4 from being arched in a direction away from the housing 2, so as to ensure that the flexible screen 4 can be folded in a direction close to the housing 2, thereby enabling the electronic device 100 to have a better folding effect.

As shown in fig. 3, when the electronic device 100 is in a folded state, that is, when the first portion 1 is folded to a final state with respect to the second portion 3, the folding region 42 is curved, the first fixing region 41 and the second fixing region 43 are disposed vertically and oppositely, and the first fixing region 41, the folding region 42 and the third fixing region 43 are located between the first portion 1 and the second portion 3. Furthermore, as shown in fig. 4 and fig. 5, when the electronic device 100 is in the flat state, that is, when the first portion 1 is flattened to the final state relative to the second portion 3, the folding region 42 may be in a planar shape or a curved shape. In addition, the plane formed by the first fastening region 41, the folding region 42 and the second fastening region 43 is between 150 ° and 180 °. Fig. 4 shows an example of 180.

In one embodiment, as shown in fig. 2 and 5, folding region 42 has a bending line 421. Folding region 42 is folded about fold line 421. It is understood that the bending line 421 of the present application is not a true line on the folding region 42, but a straight line defined in order to clearly express the position of the convex portion 50. The folding line 421 of the folding region 42 is linear. Bend line 421 is depicted in dashed lines in FIG. 3. The convex portion 50 crosses from one side of the bending line 421 to the other side of the bending line 421.

It will be appreciated that when the first portion 1 is folded with respect to said second portion 3, the fold region 42 at the fold line 421 will first arch away from the outer shell 2 if the fold region 42 has a tendency to arch away from the outer shell 2. However, since the convex portion 50 crosses from one side of the bending line 421 to the other side of the bending line 421, the stress of the flexible screen 4 at the bending line 421 is increased, so that the folding region 42 at the bending line 421 is effectively prevented from arching in a direction away from the housing 2 by the convex portion 50, i.e., the folding region 42 is ensured to be close to the housing 2.

In one embodiment, as shown in FIG. 1, the housing 2 further includes a third portion 5. The third portion 5 is connected to the first portion 1 and the second portion 3. It will be appreciated that the third portion 5 may comprise the third housing 30 of figure 3. The third portion 5 may also be a middle region of the flexible housing. The third portion 5 forms a receiving space 311. When the first portion 1 is folded relative to the second portion 3, at least a portion of the folding region 42 is received in the receiving space 311. When the first portion 1 is flattened relative to the second portion 3, at least a part of the folding area 42 is opposite to the accommodating space 311. It will be appreciated that the first and

second portions

1, 3 may be folded or unfolded relative to the third portion 5.

In one embodiment, as shown in fig. 3, the first part 1 comprises a first housing 10. The second part 3 comprises a second housing 20. The third part 5 comprises a third housing 30. The third housing 30 includes a first side 31 and a second side 32 disposed opposite to each other. The first side 31 and the second side 32 form a receiving space 311 therebetween. It will be appreciated that the third housing 30 further includes a bottom wall 33 connected to the first side 31 and the second side 32. The third housing 30 is substantially U-shaped. The first side 31 of the third housing 30 extends in a direction perpendicular to the direction from the first side 31 towards the second side 32, i.e. the direction of extension of the first side 31 is parallel to the X-axis. The second side 32 of the third housing 30 extends in a direction perpendicular to the direction from the first side 31 towards the second side 32, i.e. the second side 32 extends in a direction parallel to the X-axis. The bottom wall 33 of the third housing 30 forms the bottom wall 33 of the housing space 311. The first housing 10 is pivotally connected to the first side 31. The second housing 20 is pivotally connected to the second side 32. It will be appreciated that the first housing 10 rotates in the Y-Z plane relative to the first side 31. The second housing 20 rotates in the Y-Z plane relative to the second side 32.

Wherein the first fixing section 41 is mounted to the first housing 10 as shown in fig. 4. The second fixing section 43 is mounted to the second housing 20. Alternatively, the first fixing area 41 and the first housing 10 may be sealed by a sealing foam, and the second fixing area 43 and the second housing 20 may be sealed by a sealing foam, so as to prevent external liquid or dust from entering the inside of the electronic device 100.

In the present embodiment, the first housing 10 and the second housing 20 are configured to rotate relative to the third housing 30, so that the flexible screen 4 is folded, and the first fixing area 41 and the second fixing area 43 are configured to be opposite to each other, so as to reduce the area of the front side of the electronic device 100, that is, the area of the electronic device 100 on the X-Y plane, thereby facilitating the carrying and using of the electronic device by a user. In addition, the convex portion 50 is disposed in the folding area 42 to increase the internal stress of the flexible screen at the convex portion 50, so that when the flexible screen 4 is bent, the convex portion 50 can effectively prevent the flexible screen 4 from being folded towards a direction away from the bottom wall 33 of the accommodating space 311, that is, when the electronic device 100 is in the folding state, at least a portion of the folding area 42 is accommodated in the accommodating space 311, thereby enabling the electronic device 100 to have a better folding effect.

In the present embodiment, the convex portion 50 is provided in various ways:

the first implementation mode comprises the following steps: as shown in fig. 6, the protrusion 50 includes a first surface 51, and a first side surface 52 and a second side surface 53 opposite to each other. The first face 51 is connected between the first side face 52 and the second side face 53. The first side 52 is disposed at a first angle to the first face 51. The second side 53 is disposed at a second angle to the first face 51. The first angle is between 90 ° and 150 °. The second angle is between 90 ° and 150 °. It will be appreciated that when the first angle is 90 deg., and the second angle is also 90 deg., the projections 50 are rectangular. When the first angle is greater than 90 ° or the second angle is greater than 90 °, the convex portion 50 has a trapezoidal shape.

Further, as shown in fig. 7, the convex portion 50 includes a first region 54, a second region 55, and a third region 56. The second region 55 is connected between the first region 54 and the third region 56. The first region 54 and the third region 56 are each less thick in the first direction than the second region 55. The first direction is a direction perpendicular to the display surface of the flexible screen 4. It will be appreciated that the display surface of the flexible screen 4 faces the user when the user is using the electronic device 100. The display surface is used for realizing image display.

It is understood that by providing the second region 55 with a thickness in the first direction greater than the first region 54 with a thickness in the first direction greater than the third region 56, the first region 54 and the third region 56 share more stress, and the stress of the convex portion 50 is prevented from being excessively concentrated on the second region 55. It will be appreciated that when the projections 50 prevent the flexible screen 4 from arching away from the bottom wall 33 of the third housing 30, the flexible screen 4 will fold towards the bottom wall 33 of the third housing 30. At this point, the first and

third zones

54, 56 may share zone stresses to reduce damage to the flexible screen 4. Further, by providing the first face 51 as a curved face, the radius of curvature of the second region 55 is slightly larger than the radius of curvature of the first region 54 and the radius of curvature of the third region 56. At this time, the convex portion 50 can prevent the stress when the flexible screen 4 is folded from being excessively concentrated on the folding region 42 at the bending line, and can be more dispersed on both sides of the second region 55, thereby further reducing the risk of damaging the flexible screen 4.

Further, the center of second region 55 overlaps bend line 421. At this time, the second region 55 is located at the middle position of the convex portion 50. Therefore, when the electronic apparatus 100 changes from the flat state to the folded state, the folding region 42 is close to the bottom wall of the third housing. Since the thickness of the second region 55 in the first direction is greater than the thickness of the first region 54 and the thickness of the third region 56 in the first direction, the stress of the second region 55 is reduced, thereby preventing the flexible screen 4 from being damaged due to the excessive concentration of the stress.

In one embodiment, as shown in fig. 8, the protrusion 50 has a plurality of slits 501, and the slits 501 extend in a direction perpendicular to the second direction. The second direction is the direction in which the first side 31 faces the second side 32, i.e. the direction of the X-axis. It can be understood that when the electronic apparatus is changed from the flat state to the folded state, the flexible screen 4 is prevented from being arched away from the bottom wall of the housing space by integrally forming the convex portion 50 on the side of the body portion 40 facing the housing space 311. Furthermore, when the flexible panel 4 is close to the bottom wall 33 of the third housing 30, by providing the plurality of slits 501 on the convex portion 50, the stress of the convex portion 50 is reduced, i.e., the risk of the panel being cracked due to the stress of the convex portion 50 being too concentrated is avoided.

In one embodiment, the hardness of the protrusion 50 is greater than the hardness of the body portion 40. It is understood that, at the moment when the folding region 42 is arched away from the third housing 30 when the electronic apparatus 100 is changed from the flat state to the folded state, the convex portion 50 can prevent the flexible screen 4 from being arched away from the bottom wall 33 of the third housing 30. Furthermore, by providing the hardness of the projection 421 to be greater than the hardness of the body portion 40, the internal stress of the flexible screen 4 at the location of the projection 50 is significantly increased, thereby further avoiding the arching of the folded region 42 in a direction away from the third housing 30.

Optionally, the material of the convex portion 50 includes a metal material or glass fiber. For example, the metal material may be gold nanoparticles or silver nanoparticles. For example, when the transparent material is dropped into the concave portion of the transparent glass, the transparent material may be doped with the nano metal particles. Alternatively, some glass fiber or silica is placed in the concave portion, and then a transparent material is dropped into the concave portion of the transparent glass. At this time, when the material of the convex portion 50 includes a metal material or glass fiber, the internal stress of the convex portion 50 is significantly increased, so that at a moment when the folding region 42 is arched away from the third housing 30, the convex portion 50 can effectively prevent the flexible screen 4 from being arched away from the bottom wall 33 of the third housing 30

Alternatively, as shown in fig. 9, the outer surface of the convex portion 50 has a plurality of silica particles 502 arranged at intervals. In other embodiments, the outer surface of the protrusion 50 has a plurality of silicon nitride particles disposed at intervals. Alternatively, silica particles 502 are formed on the first face 51. Specifically, the silicon dioxide particles 502 may be formed on the outer surface of the convex portion 50 by a magnetron sputtering method. At this time, on the one hand, when the outer surface of the convex portion 50 is formed with a plurality of silica particles 502 arranged at intervals, the stress of the convex portion 50 can be increased. On the other hand, at a moment when the folded region 42 is arched away from the third housing 30, the silica particles may be pressed against each other to prevent the folded region 42 from being arched away from the third housing 30.

In one embodiment, the thickness of the protrusion 50 in the first direction is greater than the thickness of the body portion 40 in the first direction, i.e., the thickness of the protrusion 50 in the Z-axis direction is greater than the thickness of the body portion 40 in the Z-axis direction. It will be appreciated that the protrusion 50 prevents the flexible screen 4 from arching away from the bottom wall of the third housing at the instant that the fold region 42 arches away from the third housing 30 when the electronic device 100 changes from the flattened state to the folded state. Further, by providing the thickness of the convex portion 50 in the first direction to be larger than the thickness of the body portion 40 in the first direction, the thickness of the flexible screen 4 at the position of the convex portion 50 is significantly increased, so that the internal stress of the flexible screen 4 at the position of the convex portion 50 is significantly increased, thereby avoiding the arching of the folded region 42 in a direction away from the third housing 30.

Alternatively, referring again to fig. 2, the number of projections 50 is one. The convex portion 50 has a strip shape. The direction of extension of the protrusion 50 is perpendicular to the second direction, which is the direction from the first side 31 towards the second side 32. It will be appreciated that the projection 50 extends from one end of the body portion 40 to the other end of the body portion 40. At this time, when the electronic apparatus changes from the flat state to the folded state, and at a moment when the folding region 42 is arched away from the third housing 30, the convex portion 50 prevents the folding region 42 from being arched away from the third housing 30.

Alternatively, as shown in fig. 10, the number of the projections 50 is plural. The plurality of protrusions 50 are arranged at intervals, and the arrangement direction of the protrusions 50 is perpendicular to the second direction. The second direction is the direction in which the first side 31 faces the second side 32. Alternatively, the plurality of projections 50 are arranged in an array. Fig. 10 shows a plurality of projections 50 arranged in a row along the X-axis. Of course, in other embodiments, the plurality of projections 50 may be arranged in an n × n arrangement. At this time, when the electronic apparatus 100 changes from the unfolded state to the folded state, and at a moment when the folding region 42 is arched away from the third housing 30, the plurality of convex portions 50 together prevent the folding region 42 from being arched away from the third housing 30.

In the second embodiment, most of the same technical contents as those in the first embodiment are not described again: as shown in fig. 11, the convex portion 50 includes a first connection surface 503 and a second connection surface 504 connected to each other. The first connection surface 503 is disposed at a first angle to the second connection surface 504. The first angle is between 30 ° and 150 °. At this time, the shape of the convex portion 50 in the Y-Z plane is triangular, so that the stress of the flexible screen 4 at the position of the convex portion 50 is significantly concentrated, so that the convex portion 50 can effectively prevent the folding region 42 from being arched away from the third housing when the electronic apparatus 100 changes from the flat state to the folded state.

In the third embodiment, most of the same technical contents as those in the first embodiment are not described again: as shown in fig. 12, the outer surface of the protrusion 50 facing away from the body portion 40 is a curved surface. At this time, when the electronic apparatus 100 changes from the flat state to the folded state, the folding region 42 has a tendency to fold away from the third casing 30. At this time, since the stress of the flexible screen 4 at the position of the convex portion 50 is large, the convex portion 50 can effectively prevent the folding region 42 from being folded in a direction away from the third housing 30. In addition, when the folding region 42 is folded toward the direction close to the third casing 30, the convex portion 50 having the arc-shaped outer surface can reduce the stress of the convex portion 50, so that the folding region 42 can be smoothly folded to accommodate at least part of the folding region 42 in the accommodating space 311.

In one embodiment, referring again to fig. 3 to 5, the third portion 5 includes a movable plate 60. The movable plate 60 is movably mounted on the third housing 30, and the movable plate 60 is located in the accommodating space 311. The movable plate 60 is close to the folding region 42 when the first portion 1 is changed to be flat relative to the second portion 3, that is, the movable plate 60 is close to the folding region 42 when the electronic device 100 is in a flat state. The movable plate 60 is close to the bottom wall 33 of the accommodating space 311 when the first portion 1 is folded relative to the second portion 3, that is, the movable plate 60 is close to the bottom wall 33 of the accommodating space 311 when the electronic device 100 is in the folded state. Specifically, when the electronic device 100 is unfolded from the folded state to the unfolded state, the movable plate 60 moves to a direction close to the flexible screen 4. When the electronic device 100 is in the unfolded state, the movable plate 60 abuts against the protrusion 50. At this time, the movable plate 60 abuts against the protrusion 50 to ensure that the flexible screen 4 is not recessed when the flexible screen 4 is touched by a user.

Further, as shown in fig. 13, the movable plate 60 is provided with a groove 57, and an opening of the groove 57 is provided at a surface of the movable plate 60 facing the flexible screen 4, that is, the groove 57 is recessed in a direction of an inside of the movable plate 60. When the electronic device 100 is in the unfolded state, the protrusion 50 is received in the groove 57, and the surface of the movable plate 60 facing the flexible screen 4 is attached to the folding area 42. It will be appreciated that the number of recesses 57 may be one. When the electronic device 100 is in the flat state, the groove 57 can accommodate all the protrusions on the flexible screen 4 in the groove 57.

In this embodiment, the first slider 6421 has a crescent shape. The shape of the first sliding groove 612 is matched with the shape of the first slider 6421. At least a portion of the first sliding block 6421 may be received in the first sliding groove 612 and may slide relative to the first sliding groove 612. The first sliding groove 612 includes a first end 6121 and a second end 6222 disposed oppositely. The first end 6121 is the end of the first sliding slot 612 away from the first through hole 611. The second end 6122 is the end of the first sliding slot 612 near the first through hole 611. When the first casing 10 rotates relative to the third casing 30, the first casing 10 also drives the first rotating arm 61 to rotate relative to the third casing 30. At this time, during the rotation of the first rotation arm 61, since the size of the first sliding slot 612 is larger than that of the first slider 6421, the first slider 6421 slides within the first sliding slot 612. Therefore, while the first casing 10 drives the first supporting plate 64 to rotate relative to the third casing 30, the first casing 10 also drives the first supporting plate 64 to slide relative to the third casing 30. As shown in fig. 17, when the electronic device 100 is in the flattened state, the first slider 6421 is located at the second end 6122 of the first chute 612. Referring to fig. 18, when the electronic device 100 is in a folded state, the first slider 6421 slides to the first end 6121 of the first sliding groove 612.

Similarly, referring to fig. 14, by disposing the second slider 6521 on the fourth side portion 65 and disposing the second sliding slot 622 on the second rotating arm 62, the second casing 20 drives the second supporting plate 65 to rotate relative to the third casing 30, and simultaneously the second casing 20 also drives the second supporting plate 65 to slide relative to the third casing 30.
