[0036] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0037] In the following description, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0038] Furthermore, in this application, directional terms such as "upper" and "lower" are defined relative to the orientation of the components shown in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the orientation of the components in the accompanying drawings.

[0039] This application provides a foldable display terminal, which can be a mobile phone, monitor, tablet computer, in-vehicle computer, watch, e-reader, laptop computer, wearable device, or other electronic device with folding functionality. This application does not impose any special limitations on the specific form of the foldable display terminal described above. Figure 1 The illustrated embodiment uses a foldable phone as an example.

[0040] To facilitate understanding of the foldable display terminal provided in the embodiments of this application, the following description is in conjunction with the accompanying drawings. Figure 1 The following is a description of an existing foldable display terminal:

[0041] like Figure 1 As shown, the foldable display terminal 1 includes a flexible display screen 10. The flexible display screen 10 can be an active matrix organic light emitting diode (AMOLED) display screen.

[0042] The AMOLED display screen is a self-luminous display screen, and does not need to be provided with a back light module (BLM). Therefore, when a substrate substrate in the AMOLED display screen is made of a flexible resin material, such as polyethylene terephthalate (PET), the AMOLED display screen can have a bendable characteristic.

[0043] In addition, as shown in FIG. 1, the folding display terminal 1 further includes a rotating mechanism 20 for carrying the flexible display screen 10. Figure 1

[0044] The rotating mechanism 20 includes a first middle frame 201, a second middle frame 202, and a rotating shaft mechanism 203 arranged between the first middle frame 201 and the second middle frame 202.

[0045] The first middle frame 201 and the second middle frame 202 can be used to carry the flexible display screen 10, so that the flexible display screen 10 can be kept as flat as possible during use, and the non-display surface of the flexible display screen 10 is protected.

[0046] A part of the flexible display screen 10 is fixed to the first middle frame 201 by a glue layer 30, a part is fixed to the second middle frame 202 by the glue layer 30, and a part is fixed to the rotating shaft mechanism 203 by the glue layer 30. The glue layer 30 can be a thin film layer formed after the glue is coated, and the specific form of the glue layer 30 is not limited in the embodiments of the present application. In addition, other electronic elements, such as a camera, a headset, a receiver, a key, a battery, etc., can also be arranged on the first middle frame 201 and the second middle frame 202, and the other electronic elements arranged on the first middle frame 201 and the second middle frame 202 are not limited in the embodiments of the present application.

[0047] In some embodiments, the flexible display screen 10 can include a non-bending area 101 corresponding to the first middle frame 201, a non-bending area 102 corresponding to the second middle frame 202, and a bending area 103 corresponding to the rotating shaft mechanism 203. The bending area 103 can be connected between the non-bending area 101 and the non-bending area 102.

[0048] The non-bending area 101 can be connected to the first middle frame 201, and the non-bending area 102 can be connected to the second middle frame 202.

[0049] ​The rotating shaft mechanism 203 can be connected between the first middle frame and the second middle frame. The bending area 103 of the flexible display screen 10 can be fixed on the rotating shaft mechanism 203. Under the action of the rotating shaft mechanism 203, the first middle frame and the second middle frame can be close to or away from each other. Correspondingly, the non-bending area 101 of the flexible display screen 10 and the non-bending area 102 of the flexible display screen 10 can be close to or away from each other, so that the flexible display screen 10 can be folded or unfolded.

[0050] When the folding display terminal 1 is in the folded state, the first middle frame 201 and the second middle frame 202 can be arranged in parallel and opposite to each other, and the interval distance between the first middle frame 201 and the second middle frame 202 is the smallest. Similarly, the non-bending area 101 and the non-bending area 102 can be arranged in parallel and opposite to each other, and the interval height between the non-bending area 101 and the non-bending area 102 is the smallest. At this time, the non-bending area 101 and the non-bending area 102 can be regarded as being arranged on different planes.

[0051] Figure 1 The folding display terminal 1 shown is in an unfolded state. In the unfolded state, the angle between the first middle frame 201 and the second middle frame 202 can be about 180°, and the flexible display screen 10 can be in the unfolded state as shown. Figure 1 The folding display terminal 1 shown is in an unfolded state.

[0052] The foldable electronic device can be unfolded to a flat state, or folded to a closed state, or in an intermediate state between the flat state and the closed state. The foldable electronic device has at least two states, i.e., the flat state and the closed state. In some cases, a third state, i.e., an intermediate state between the flat state and the closed state, can be further included. The intermediate state is not only a unique state, but can be any one or more states between the flat state and the closed state.

[0053] In some embodiments, the folding display terminal adopts an outer folding design, and in the folded state, the flexible display screen 10 is located on the outer side of the device.

[0054] In some other embodiments, the folding display terminal adopts an inner folding design, and in the folded state, the flexible display screen 10 is located on the inner side of the device.

[0055] The above Figure 1 An example is a dual-screen electronic device. The folding electronic device related to the embodiments of the present application can also be a device with more screens, such as a three-screen folding, four-screen folding, five-screen folding, etc.

[0056] The following will be described taking a dual-screen folding electronic device as an example. Figure 2 is a structural schematic view of a display screen assembly. As Figure 2As shown, in order to protect the flexible display screen 10, the electronic device further comprises a support 40, which is arranged on the backlight side of the flexible display screen 10, and is used to provide reliable support for the flexible display screen 10.

[0057] The support can be used in a foldable terminal as a flexible display screen under-screen support structure. For example, the support 40 can be a bamboo book structure.

[0058] As shown in Figure 2 , the support 40 is arranged below the flexible display screen 10.

[0059] Embodiments of the present application do not limit the structure of the support. In some embodiments, referring to Figure 2 , Figure 3 , the support 40 comprises a bending part 403 and support parts (401 and 402), which are distributed along a direction perpendicular to the thickness direction of the support 40 when the display screen is in a flat state. The bending part 403 is in a bent state when the display screen is in a folded state.

[0060] As shown in Figure 2 , Figure 3 , the support 40 comprises a first support part 401 connected with the non-bending area 101, a second support part 402 connected with the non-bending area 102, and a bending part 403 connected with the bending area 103.

[0061] The bending part 403 is arranged between the first support part 401 and the second support part 402 when the display screen is in a flat state.

[0062] As shown in Figure 3 , the display screen assembly is in a U shape when in a bent state. In other embodiments, as shown in Figure 4 , the display screen assembly is in a water drop shape when in a bent state.

[0063] For example, as shown in Figure 4 , the flexible display screen 10 can comprise a non-bending area 101, a bending area 104, a non-bending area 106, a bending area 103, a non-bending area 107, a bending area 105, and a non-bending area 102 connected in sequence.

[0064] In some embodiments, the support 40 can comprise a support part, a connecting part and a bending part connected in sequence. The bending part and the support part are distributed along a direction perpendicular to the thickness direction of the support when the display screen is in a flat state.

[0065] The support part includes a first support part 401 and a second support part 402, and the bending part includes a first bending part 403, a second bending part 404, and a third bending part 405. The connecting part includes a first connecting part 406 and a second connecting part 407.

[0066] The first support part 401, the second bending part 404, the first connecting part 406, the first bending part 403, the second connecting part 407, the third bending part 405, and the second support part 402 are sequentially connected.

[0067] The first support part 401 can be connected to the non-bending area 101 to provide mechanical support for the non-bending area 101. The second support part 402 can be connected to the non-bending area 102 to provide mechanical support for the non-bending area 102. The first bending part 403 can be connected to the bending area 103 to provide mechanical support for the bending area 103. The second bending part 404 can be connected to the bending area 104 to provide mechanical support for the bending area 104. The third bending part 405 can be connected to the bending area 105 to provide mechanical support for the bending area 105. The first connecting part 406 can be attached to the non-bending area 106 to provide mechanical support for the non-bending area 106. The second connecting part 407 can be attached to the non-bending area 107 to provide mechanical support for the non-bending area 107.

[0068] In one example, when the flexible display screen 10 is in the unfolded state, the non-bending area 101, the bending area 104, the bending area 103, the bending area 105, and the non-bending area 102 can all be in a flat state.

[0069] Correspondingly, when the flexible display screen 10 is in the unfolded state, the support piece 40 can be in the unfolded state, and the first support part 401, the second bending part 404, the first bending part 403, the third bending part 405, and the second support part 402 can all be in a flat state. The first support part 401 in a flat state can mean that any two different positions of the first support part 401 can be regarded as being arranged on the same plane.

[0070] As Figure 4As shown, in the case that the flexible display screen 10 is in the folded state, the bending area 103 can be in a curved state. Correspondingly, the first bending part 403 can be in a curved state. The non-bending area 101 and the non-bending area 102 can both be in a flat state. Correspondingly, the first support part 401 and the second support part 402 can both be in a flat state. The bending area 104 and the bending area 105 can both be in a (micro-) curved state (the curved radius in the (micro-) curved state can be smaller than the curved radius in the folded state), wherein the curved radius of the bending area 104 can be smaller than the curved radius of the bending area 103, and the curved radius of the bending area 105 can be smaller than the curved radius of the bending area 103. The bending area 104 can play a transition role between the flat state of the non-bending area 101 and the curved state of the bending area 103, and the bending area 105 can play a transition role between the flat state of the non-bending area 102 and the curved state of the bending area 103. The second bending part 404 and the third bending part 405 can both be in a (micro-) curved state, wherein the curved radius of the second bending part 404 can be smaller than the curved radius of the first bending part 403, and the curved radius of the third bending part 405 can be smaller than the curved radius of the first bending part 403. The second bending part 404 can play a transition role between the flat state of the first support part 401 and the curved state of the first bending part 403, and the third bending part 405 can play a transition role between the flat state of the second support part 402 and the curved state of the first bending part 403.

[0071] In order to improve the bending performance of the support, in some embodiments, a through hole can be arranged in the bending part (403, 404, 405) of the support. Figure 2 The through hole arranged in the bending part (403, 404, 405) of the support can improve the bending performance of the bending part of the support. Figure 4 The through hole arranged in the bending part (403, 404, 405) of the support can improve the bending performance of the bending part of the support.

[0072] In some embodiments, the adhesive material can also be filled in the through hole. By filling the adhesive material in the through hole, the reliability of the display module can be improved. However, when subjected to use conditions such as water vapor, dust, grease and frequent bending friction, the adhesive material in the through hole can fail, and even an unrecoverable mold mark can be generated on the screen surface. Therefore, an improved support is provided in the embodiments of the present application, which can be provided with a protective layer on the bending part, and the protective layer can isolate the adhesive material in the through hole from the external environment.

[0073] The protective layer can be used, for example, in the bending part 403, and the support adopting the structure can be used in a folding display terminal in a U-shaped folded state. The protective layer can also be used, for example, in the first bending part 403, the second bending part 404 and the third bending part 405. Figure 2 The support adopting the structure can be used in a folding display terminal in a U-shaped folded state. Figure 4The first bending part 403, the second bending part 404 and the third bending part 405 are shown. The support member with the structure can be used in a folding display terminal in a water drop shape in a bending state. The present application uses the protective layer for a folding display terminal as shown in Figure 2 The bending part 403 of the support member is described by way of example.

Figure 6 A structural schematic diagram of a display screen assembly provided in an embodiment of the present application is shown. As shown in Figure 5 、 Figure 6 The support member includes a bending part 403, support parts (401 and 402) and a first protective layer 50.

[0075] As shown in Figure 6 When the display screen 10 is in an unfolded state, the bending part 403 and the support parts (401 and 402) are distributed along a direction perpendicular to the thickness direction of the support member 40.

[0076] When the display screen 10 is in a folded state, the bending part 403 is in a bending state.

[0077] As shown in Figure 5 The bending part 403 includes a first area (403A, 403B) including a first through hole 4001 filled with a glue material, and the first protective layer 50 is arranged on a side of the first area (403A, 403B) away from the flexible display screen, and the first protective layer 50 is used to cover the first through hole 4001.

In some embodiments, the material of the glue material includes a liquid optical clear adhesive (LOCA) optical glue or a hydrogel. The liquid optical clear adhesive has a transmittance of 98% or more, strong fluidity, good adhesive strength and can be cured at room temperature or medium temperature.

[0079] The support member provided in the present embodiment has a through hole in the bending part filled with a glue material with strong fluidity, which can improve the bending reliability and impact resistance of the bending part.

[0080] The support provided in the present application is provided with a first protective layer 50 on the surface of the first area (403A, 403B), the adhesive material filled in the first through hole 4001 can be isolated from the external environment through the first protective layer 50, so as to avoid the invasion of water vapor, dust, grease and the like in the external environment into the adhesive material, meanwhile, the first protective layer 50 isolates the adhesive material filled in the through hole from the rotating shaft structure, reduces the influence of frequent bending on the adhesive property of the adhesive material, and can better protect the adhesive material and improve the reliability of the display module.

[0081] The material and size of the first protective layer 50 are not limited in the embodiments of the present application. In some embodiments, the material of the first protective layer 50 includes at least one of a high molecular film, a metal film or a fiber composite film. For example, the high molecular film includes at least one of polyurethane (PU) or polyimide (PI). The material of the metal film includes stainless steel. The material of the fiber composite film includes Kevlar fiber.

[0082] In some embodiments, the thickness of the first protective layer 50 is 5-150 μm. In this way, the thickness of the first protective layer 50 is relatively thin, which is beneficial to the thinning of the whole electronic device.

[0083] The connection mode of the first area (403A, 403B) and the first protective layer 50 is not limited in the embodiments of the present application. In some embodiments, as shown in Figure 7 the support further includes a connecting layer 51, the connecting layer 51 is arranged between the first area (403A, 403B) and the first protective layer 50, and the first protective layer 50 can be connected with the first area (403A, 403B) through the connecting layer 51.
