Description
Technical Field
The invention relates to the technical field of electronic products, in particular to a flexible screen and foldable electronic equipment using the flexible screen.
Background
With the continuous development of technology, more and more foldable electronic devices (such as foldable mobile phones, foldable tablet computers and the like) are appeared in the work and life of people. Flexible screens, an important component of foldable electronic devices, are generally obtained by stacking a plurality of materials. However, due to the multi-layer structure design of the flexible screen, the display layer in the flexible screen is easily dislocated to contact with the external hard structure during transportation, assembly, mechanical testing, and the like, so that the display layer is damaged, and the flexible screen is discarded.
Disclosure of Invention
The invention mainly aims to provide a flexible screen and foldable electronic equipment applying the flexible screen, and aims to reduce the damage probability of a display layer in the flexible screen due to dislocation in the processes of transportation, assembly, mechanical test and the like and reduce the rejection probability of the flexible screen.
An embodiment of the present invention provides a flexible screen, including:
a display layer; and
the supporting layer is arranged on one side of the display layer in a stacking mode, and the outer edge of the supporting layer exceeds the outer edge of the display layer.
An embodiment of the present invention proposes a foldable electronic device comprising a foldable housing assembly and a flexible screen, the flexible screen comprising:
a display layer; and
the supporting layer is arranged on one side of the display layer in a laminated mode, and the outer edge of the supporting layer is arranged beyond the outer edge of the display layer;
the flexible screen is laid on the foldable shell component.
In the technical scheme of the invention, because the outer edge of the supporting layer exceeds the outer edge of the display layer, even if the display layer in the flexible screen is dislocated in the processes of transportation, assembly, mechanical test and the like, when the dislocated degree is not enough to enable the outer edge of the display layer to exceed the outer edge of the supporting layer, the supporting layer is contacted with the external hard structure, but not the display layer is contacted with the external hard structure. That is, a certain amount of misalignment will no longer cause the display layer in the flexible screen to come into contact with the external rigid structure, since the outer edge of the support layer exceeds the outer edge of the display layer. Therefore, the probability of damage to the display layer in the flexible screen due to dislocation in the processes of transportation, assembly, mechanical testing and the like is reduced, and the rejection probability of the flexible screen is reduced.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Flexible screens, an important component of foldable electronic devices, are generally obtained by stacking a plurality of materials. However, due to the multi-layer structure design of the flexible screen, the display layer in the flexible screen is easily dislocated to contact with the external hard structure during transportation, assembly, mechanical testing, and the like, so that the display layer is damaged, and the flexible screen is discarded.
In view of the above technical problems, the present invention provides a flexible screen 100, which aims to reduce the probability of damage to the display layer 10 of the flexible screen 100 due to dislocation during transportation, assembly, mechanical testing, and the like, and reduce the probability of rejection of the flexible screen 100.
It is to be understood that the flexible screen 100 is applicable to a foldable electronic device, which may be, but not limited to, a foldable mobile phone, a foldable tablet computer, a foldable Personal Digital Assistant (PDA), a foldable e-book reader, a foldable MP3 (motion Picture Experts Group Audio Layer III) player, a foldable MP4 (motion Picture Experts Group Audio Layer IV) player, a foldable wearable device, a foldable navigator, a foldable handheld game console, etc.
The following describes a specific structure of the flexible screen 100 according to a specific embodiment, and takes the flexible screen 100 as an example of a horizontal position:
as shown in fig. 1 to 3, in an embodiment of the flexible screen 100 of the present invention, the flexible screen 100 includes:
a display layer 10; and
and a support layer 30, wherein the support layer 30 is stacked on one side of the display layer 10, and the outer edge of the support layer 30 is arranged beyond the outer edge of the display layer 10.
It should be noted that, the outer edge of the support layer 30 exceeds the outer edge of the display layer 10, which means that when the flexible screen 100 is in a flat state, an orthographic projection of the display layer 10 on the front surface of the support layer 30 completely falls within the range of the front surface of the support layer 30, and an outline of the orthographic projection of the display layer 10 on the front surface of the support layer 30 does not coincide with an outline of the front surface of the support layer 30.
At this time, since the outer edge of the support layer 30 exceeds the outer edge of the display layer 10, even if the display layer 10 in the flexible screen 100 is dislocated during transportation, assembly, mechanical testing, etc., when the dislocated extent is not enough to make the outer edge of the display layer 10 exceed the outer edge of the support layer 30, the support layer 30 is in contact with the external hard structure, and the display layer 10 is not in contact with the external hard structure. That is, because the outer edge of the support layer 30 exceeds the outer edge of the display layer 10, some misalignment will no longer cause the display layer 10 in the flexible screen 100 to contact the external rigid structure. Thus, the probability of damage to the display layer 10 of the flexible screen 100 due to dislocation during transportation, assembly, mechanical testing and the like is reduced, and the probability of scrapping of the flexible screen 100 is reduced.
Further, the flexible screen 100 further includes a protective layer 50, the protective layer 50 is stacked on a side of the display layer 10 facing away from the support layer 30, and an outer edge of the support layer 30 is disposed beyond an outer edge of the protective layer 50.
It should be noted that the outer edge of the support layer 30 exceeds the outer edge of the protection layer 50, which means that when the flexible screen 100 is in a flat state, an orthographic projection of the protection layer 50 on the front surface of the support layer 30 completely falls within the range of the front surface of the support layer 30, and an outline of the orthographic projection of the protection layer 50 on the front surface of the support layer 30 does not coincide with an outline of the front surface of the support layer 30.
At this time, since the outer edge of the support layer 30 is beyond the outer edge of the protective layer 50, even if the protective layer 50 in the flexible panel 100 is dislocated during transportation, assembly, mechanical testing, etc., when the dislocation is not enough to make the outer edge of the protective layer 50 beyond the outer edge of the support layer 30, the support layer 30 is in contact with the external hard structure, and not the protective layer 50 is in contact with the external hard structure. That is, since the outer edge of the support layer 30 also exceeds the outer edge of the protective layer 50, a certain amount of misalignment does not cause the protective layer 50 in the flexible screen 100 to come into contact with the external hard structure. Thus, the probability of damage to the protective layer 50 of the flexible screen 100 due to dislocation during transportation, assembly, mechanical testing and the like is reduced, and the probability of scrapping the flexible screen 100 is reduced.
On the other hand, between the outer edge of the display layer 10 and the outer edge of the protective layer 50, there are at least two relationships:
first, the outer edge of the display layer 10 is disposed beyond the outer edge of the protective layer 50 (as shown in FIG. 3). At this time, the outer edge of the display layer 10 may be used to further protect the protective layer 50. It will be appreciated that such an arrangement is suitable for use where the protective layer 50 is more "fragile", for example where the protective layer 50 is a glass layer.
Second, the outer edge of the protective layer 50 is disposed beyond the outer edge of the display layer 10 (as shown in fig. 5). At this time, the outer edge of the protective layer 50 may serve to further protect the display layer 10. It will be appreciated that such an arrangement is suitable for use where the display layer 10 is more "fragile", for example where the protective layer 50 is a transparent polyimide layer.
Note that "overrun" in which the outer edge of the display layer 10 exceeds the outer edge of the protective layer 50, "overrun" in which the outer edge of the protective layer 50 exceeds the outer edge of the display layer 10 "is defined as the aforementioned" overrun "in which the outer edge of the support layer 30 exceeds the outer edge of the display layer 10" (or "overrun" in which the outer edge of the support layer 30 exceeds the outer edge of the protective layer 50); therefore, the same understanding can be made. Also, the "excess" in the following is also defined the same as the aforementioned "excess" in which the outer edge of the support layer 30 exceeds the outer edge of the display layer 10 (or "excess" in which the outer edge of the support layer 30 exceeds the outer edge of the protective layer 50); therefore, the same understanding can be made.
Specifically, in the embodiment shown in fig. 3, the display layer 10 is sandwiched between the back film 10a and the polarizer 10b, that is, the back film 10a, the display layer 10 and the polarizer 10b are sequentially stacked; wherein the display layer 10 is an active matrix organic light emitting diode panel.
The protective layer 50 is arranged on one side of the polarizer 10b, which is opposite to the display layer 10, an optical adhesive layer 50d is arranged between the protective layer 50 and the polarizer 10b, and the protective layer 50 is adhered to the polarizer 10b through the optical adhesive layer 50 d; that is, the surface of the optical adhesive layer 50d facing away from the protective layer 50 is attached to the surface of the polarizer 10b facing away from the display layer 10; among them, the protective layer 50 may be a transparent polyimide layer, a transparent polyethylene terephthalate layer, a transparent triacetyl cellulose layer, a transparent polycarbonate layer, or the like.
The supporting layer 30 is arranged on one side of the back film 10a, which faces away from the display layer 10, an adhesive layer 30a is arranged between the supporting layer 30 and the back film 10a, and the supporting layer 30 is adhered to the back film 10a through the adhesive layer 30 a; that is, the surface of the adhesive layer 30a facing away from the support layer 30 is attached to the surface of the back film 10a facing away from the display layer 10; the supporting layer 30 may be a steel sheet, a copper alloy sheet, etc., and the adhesive layer 30a may be a pressure-sensitive adhesive layer, a foam adhesive layer, etc.
Of course, the protective layer 50 can also be configured appropriately according to actual requirements, specifically as follows:
as shown in fig. 6, in an embodiment of the flexible screen 100 of the present invention, the protective layer 50 includes a glass layer 50 a. Note that Ultra-Thin Glass (UTG for short) is used as the Glass layer 50 a. The ultrathin glass, also called ultrathin flexible glass or flexible ultrathin glass, is a special glass material which is processed by a strengthening process and has flexibility meeting the use requirement of a flexible screen, and also has smooth hand feeling and good uniformity. For example: the three-star folding screen mobile phone Galaxy Z Flip adopts ultrathin glass as a cover plate of a flexible screen.
It can be understood that, in the solution where the protection layer 50 is only composed of the transparent polyimide layer, since the transparent polyimide layer has a certain flexibility, there is no glass touch compared with the conventional glass cover plate; moreover, as the surface hardness of the transparent polyimide layer is low, scratches are easily left on the surface in the using process, and the surface is not easy to recover in a short time, so that irreversible damage is easily caused, normal display of equipment is even influenced, and user experience is reduced. Therefore, by configuring the protective layer 50 as the glass layer 50a, not only can good surface hardness be provided for the protective layer 50, the generation of surface scratches is avoided, the surface damage is avoided, and the normal display of the device is ensured; but also can provide the similar surperficial sense of touch with traditional glass apron for the user to promote user experience.
Further, in the embodiment shown in fig. 6, in order to protect the glass layer 50a to a certain extent, reduce the risk of damaging the glass layer 50a, prolong the service life of the glass layer 50a, and improve the reliability of the flexible screen 100, the protection layer 50 may further be configured as follows:
the protective layer 50 further includes a transparent isolation layer 50b, the glass layer 50a and the transparent isolation layer 50b are stacked, and the transparent isolation layer 50b is stacked on a side of the glass layer 50a facing away from the display layer 10. Specifically, an optical adhesive layer is disposed between the glass layer 50a and the transparent isolation layer 50b, and the glass layer 50a is bonded to the transparent isolation layer 50b through the optical adhesive layer. The transparent isolation layer 50b may be a transparent polyimide layer, a transparent polyethylene terephthalate layer, a transparent cellulose triacetate layer, a transparent polycarbonate layer, or the like.
Further, in the embodiment shown in fig. 6, in order to better alleviate the impact of the protection layer 50 on the display layer 10 when being pressed, reduce the risk of damage to the display layer 10, prolong the service life of the display layer 10, and improve the reliability of the flexible screen 100, the protection layer 50 may further be configured as follows:
the protective layer 50 further includes a transparent buffer layer 50c, the transparent buffer layer 50c and the glass layer 50a are stacked, and the transparent buffer layer 50c is stacked on a side of the glass layer 50a facing the display layer 10. Specifically, an optical adhesive layer is disposed between the transparent buffer layer 50c and the glass layer 50a, and the glass layer 50a is bonded to the transparent buffer layer 50c through the optical adhesive layer. The transparent buffer layer 50c may be a transparent polymethyl methacrylate layer, a transparent polyurethane layer, or the like.
Referring to fig. 1, fig. 2 and fig. 4, in an embodiment of the flexible screen 100 of the present invention, the supporting layer 30 is folded inwards along with the flexible screen 100 to form a first bending region 31, the supporting layer 30 has two first side edges 33 disposed oppositely, the two first side edges 33 are respectively located at two sides of the first bending region 31 and both are disposed oppositely to the first bending region 31;
the display layer 10 is folded inwards along with the flexible screen 100 to form a second bending area 11, the display layer 10 is provided with two second side edges 13 which are arranged back to back, the two second side edges 13 are respectively positioned at two sides of the second bending area 11 and are both arranged back to the second bending area 11;
the protective layer 50 is folded inwards along with the flexible screen 100 to form a third bending area 51, the protective layer 50 is provided with two third side edges 53 which are arranged back to back, the two third side edges 53 are respectively positioned at two sides of the third bending area 51 and are both arranged back to the third bending area 51;
when the flexible screen 100 is in the folded-in state, the first side edge 33 is disposed beyond the second side edge 13, and the first side edge 33 is disposed beyond the third side edge 53.
Thus, even if the flexible screen 100 is folded inwards, the second side edge 13 of the display layer 10 is dislocated outwards relative to the first side edge 33 of the supporting layer 30, but the first side edge 33 of the supporting layer 30 still exceeds the second side edge 13 of the display layer 10, so that the display layer 10 is prevented from contacting with an external hard structure when the flexible screen 100 is folded inwards, the display layer 10 is protected, the probability that the display layer 10 in the flexible screen 100 is damaged due to the outward dislocated in the process of folding inwards the flexible screen 100 is reduced, and the rejection probability of the flexible screen 100 is reduced.
Similarly, even if the flexible screen 100 is folded inwards, the third side edge 53 of the protection layer 50 moves outwards relative to the first side edge 33 of the support layer 30, but the first side edge 33 of the support layer 30 still exceeds the third side edge 53 of the protection layer 50, so that the protection layer 50 is prevented from contacting with an external hard structure when the flexible screen 100 is folded inwards, the protection of the protection layer 50 is formed, the probability that the protection layer 50 in the flexible screen 100 is damaged due to the outward movement in the process of folding inwards the flexible screen 100 is reduced, and the rejection probability of the flexible screen 100 is reduced.
Further, in the embodiment shown in fig. 1, 2 and 4, one of the two first side edges 33 is provided with an avoidance gap 331, an opening of the avoidance gap 331 is disposed opposite to the first bending area 31, the flexible screen 100 further includes a connecting portion 70 and a bending portion 90, the connecting portion 70 is disposed on one side of the supporting layer 30 opposite to the display layer 10 in a stacked manner, and the bending portion 90 is disposed through the avoidance gap 331 and connected to the second side edge 13 of the display layer 10 and the side edge of the connecting portion 70 facing the avoidance gap 331.
Specifically, in the present embodiment, the connection portion 70 and the bending portion 90 are all an active matrix organic light emitting diode panel, and the display layer 10, the bending portion 90 and the connection portion 70 are integrally prepared, integrally cut, and arranged in the flexible screen 100 after bending the bending portion 90. A back film and an adhesive layer are sequentially laminated between the connection portion 70 and the support layer 30.
Thus, the display layer 10 can be electrically connected with an external circuit system through the connecting portion 70 located on the back of the supporting layer 30, which is simple, convenient and reliable; meanwhile, the arrangement of the electrical connection relation on the back of the supporting layer 30 can also effectively reduce the volume of the middle frame of the foldable electronic device. Moreover, the avoiding notch 331 is utilized to avoid the bending portion 90 in the horizontal direction, so that the bending portion 90 can be accommodated in the avoiding notch 331 in the horizontal direction, and the outer side surface of the bending portion 90 is located within the first side edge 33 provided with the avoiding notch 331, thereby ensuring that the bending portion 90 does not contact with an external hard structure, reducing the probability of damage of the bending portion 90, improving the stability of the electrical connection between the display layer 10 and an external circuit system, and improving the reliability of the flexible screen 100.
Further, in the embodiment shown in fig. 1, fig. 2 and fig. 4, a protective adhesive layer 90a is disposed on an outer surface of the bending portion 90, and the protective adhesive layer 90a is disposed through the avoiding notch 331. At this time, the protective adhesive layer 90a can further protect the bending portion 90, so as to reduce the probability of damage to the bending portion 90, thereby further improving the stability of electrical connection between the display layer 10 and an external circuit system, and improving the reliability of the flexible screen 100.
