The embodiment of the present application does not specially limit the specific form of the folding display terminal. For convenience of description, the following embodiments are all exemplified by using a foldable display terminal as a mobile phone.

As an example of a structure of a folding display terminal, as shown in fig. 1A, a folding display terminal 1 includes a display area 10 and a peripheral area 20.

The peripheral area 20 is located at the periphery of the display area 10, and the peripheral area 20 may surround the display area 10, or may be disposed on one side, two sides, or three sides of the display area 10.

The peripheral region 20 includes a package region 21 and a peripheral circuit region 22, and the peripheral circuit region 22 is located on a side of the package region 21 close to the display region 10.

The peripheral circuit region 22 is located between the package region 21 and the display region 10.

Illustratively, the peripheral circuit region 22 may surround the display region 10, i.e., the peripheral circuit region is disposed around the display region 10.

Alternatively, the peripheral circuit region 22 may be disposed on one side, two sides, or three sides of the display region 10, for example. The embodiment of the application does not limit the method and can be reasonably set according to needs.

As shown in fig. 1A, the foldable display terminal 1 may have a size in a folded state that is a size of a general mobile phone and a size in an unfolded state that is twice a size of the general mobile phone. Alternatively, as shown in fig. 1B, the folding display terminal 1 may have a size in the unfolded state that is the size of a general mobile phone, and a size in the folded state that is half the size of a general mobile phone. The embodiment of the present application does not limit this.

As shown in fig. 1C, the foldable display terminal 1 mainly includes a display module 2, a middle frame 3, a rear cover (or referred to as a battery cover, a rear case) 4, and a cover plate 5.

As shown in fig. 1D, the foldable display terminal 1 may be divided into a bending region 210, a first non-bending region 221 and a second non-bending region 222 according to another dividing manner. The bending region 210 is disposed between the first non-bending region 221 and the second non-bending region 222.

When the foldable display terminal 1 is in a folded state, the bending region 210 is bent, and the first non-bending region 221 and the second non-bending region 222 are disposed opposite to each other.

The material of the bending region 210 of the display module 2 is a flexible material. The material of the first non-bending region 221 and the second non-bending region 222 may be a flexible material, or may be a rigid material, or may be a partially flexible material, or a partially rigid material. The embodiment of the present application does not limit this.

The display module 2 has a light-emitting side from which a display screen can be viewed and a back surface disposed opposite to the light-emitting side. The light-emitting side of the display module 2 is far away from the middle frame 3, that is, the back of the display module 2 is close to the middle frame 3. The cover plate 5 is arranged on the light-emitting side of the display module 2.

The display module 2 includes a Display Panel (DP).

In one possible embodiment of the present application, the display module 2 is a liquid crystal display module. In this case, the display screen is a Liquid Crystal Display (LCD). Based on this, the display module 2 further includes a backlight unit (BLU) located on the back side of the liquid crystal display (a side surface away from the LCD for displaying pictures).

The backlight module can provide light source for the liquid crystal display screen, so that each sub-pixel in the liquid crystal display screen can emit light to realize image display.

Alternatively, in another possible embodiment of the present application, the display module 2 is an organic light emitting diode display module. In this case, the display screen is an Organic Light Emitting Diode (OLED) display screen, a Micro organic light emitting diode (Micro-LED) display screen, a sub-millimeter light emitting diode (Mini-LED) display screen, a quantum dot light emitting diode (QLED) display screen, or an Active Matrix Organic Light Emitting Diode (AMOLED) display screen. Because the electroluminescent layer is arranged in each sub-pixel in the OLED display screen, the OLED display screen can realize self-luminescence after receiving the working voltage. In this case, the display module 2 having the OLED display does not need to be provided with the backlight module.

When the substrate of the display module 2 is made of a flexible resin material, such as polyethylene terephthalate (PET), the display module 2 can be bendable.

It is explained here that the display module 2 is located in the display area 10, the package portion of the display module 2 is located in the package area 21 of the peripheral area 20, and the peripheral circuit portion of the display module 2 is located in the peripheral circuit area 22 of the peripheral area 20.

The cover plate 5 is located on a side of the display module 2 away from the middle frame 3, and the cover plate 5 may be, for example, flexible glass (CG), which may have certain toughness.

The middle frame 3 is located between the display module 2 and the rear cover 4, and the surface of the middle frame 3 away from the display module 2 is used for mounting internal components such as a battery, a Printed Circuit Board (PCB), a camera (camera), and an antenna. After the rear cover 4 is covered with the middle frame 3, the internal elements are positioned between the rear cover 4 and the middle frame 3.

As shown in fig. 1A, the middle frame 3 includes a rotating shaft 310, a first structural member 321, and a second structural member 322. The first structural member 321 and the second structural member 322 are located at two opposite sides of the rotating shaft 310 and are respectively connected to the rotating shaft 310 in a rotating manner.

The first structural member 321 and the second structural member 322 may be used to bear the display module 2, so that the display module 2 is kept as flat as possible during the use process, and the back of the display module 2 is protected.

For example, the first structure member 321 is supported and attached on the first non-bending region 221 of the display module 2, the second structure member 322 is supported and attached on the second non-bending region 222 of the display module 2, and the rotating shaft 310 is supported and attached on the bending region 210 of the display module 2. The first structural member 321 and the second structural member 322 are respectively connected to the rotating shaft 310, so as to drive the display module 2 to fold or unfold.

As shown in fig. 2A, when the included angle α between the first structural member 321 and the second structural member 322 is 180 °, the folding display terminal 1 is in the unfolded state.

As shown in fig. 2B, when the angle α between the first and second

structural members

321 and 322 is 0 °, the foldable display terminal 1 is in a folded state.

As shown in fig. 2C, when the included angle α between the first structural member 321 and the second structural member 322 is 90 °, the folded display terminal 1 is in a state to be folded or unfolded.

Fig. 2D is an unfolding process of the folding display terminal 1 from 180 ° to 0 °, or a folding process of the folding display terminal 1 from 0 ° to 180 °.

In addition, other electronic elements, such as a camera, an earphone, a headphone, a button, a battery, and the like, may also be disposed on the first structural member 321 and the second structural member 322.

In some embodiments, the foldable display terminal 1 further comprises a bezel (not shown) that is disposed around the middle frame 3. The frame and the middle frame 3 can be integrally formed structural members. Or, the frame and the middle frame 3 can also be two separate structural members, and the frame and the middle frame 3 can be assembled by one or more combinations of assembling modes such as clamping, gluing, welding and the like. The embodiment of the present application does not limit this.

The frame sets up around display module assembly 2's profile round, closes with apron 5 and back lid 4 and closes and form sealed casing, plays the guard action to display module assembly 2.

As shown in fig. 2D, when the foldable display terminal 1 is folded from the unfolded state to the folded state, the first non-bending region 221 rotates around a point a in the figure (point a is a connection point of the first non-bending region 221 and the bending region 210), and the second non-bending region 222 rotates around a point B in the figure (point B is a connection point of the second non-bending region 222 and the bending region 210). When the positions of the points a and B are not changed, the bending region 210 of the display module 2 may have a certain amount of downward movement in the folded position compared to the unfolded position.

Therefore, when folding display terminal 1 is in fold condition, have certain clearance between display module assembly 2 and the center 3, lead to inside dust or the foreign matter gets into folding display terminal 1, lead to folding display terminal 1 to damage.

Based on this, in order to avoid dust or foreign matters from entering the interior of the foldable display terminal 1 and causing the foldable display terminal 1 to be damaged, the embodiment of the present application provides a foldable display terminal, as shown in fig. 3A, the foldable display terminal 1 mainly includes a display module 2, a middle frame 3, a rear cover 4, a cover plate 5 and a protection component 100.

The display module 2 may be any of the display modules described above, and reference may be made to the description of the display module 2, which is not repeated herein.

The middle frame 3, the rear cover 4 and the cover plate 5 can refer to the above description about the middle frame 3, the rear cover 4 and the cover plate 5, and are not described again here.

As shown in fig. 3B, the shield assembly 100 includes a shield portion 110 and a connecting portion 120 that are connected to and intersect with each other.

The connecting portion 120 is located outside the display module 2 and connected to the rotating shaft 310. The shielding portion 110 extends to the light emitting side of the display module 2.

In this kind of folding display terminal 1, utilize protection component 100 to shelter from the gap between display module assembly 2 and pivot 310, avoid inside dust or foreign matter get into folding display terminal 1, lead to folding display terminal 1 to damage.

However, the use of the shield assembly 100 can prevent dust or foreign materials from entering the interior of the foldable display terminal 1, but it may cause new problems.

As shown in fig. 3B, the shielding portion 110 is located in the encapsulation area 21 of the peripheral area 20. There is a gap between the shielding part 110 and the display module 2, and in order to reduce dust or foreign matters from entering the foldable display terminal 1 through the gap between the shielding part 110 and the display module 2, the gap between the shielding part 110 and the display module 2 needs to be reduced as much as possible.

However, due to the existence of the shielding assembly 100, when the foldable display terminal 1 is in the folded state, the shielding portion 110 may contact the display module 2, and a portion of the display module 2 located in the encapsulation area 21 is subject to concentrated stress caused by the shielding portion 110. And because the encapsulation area 21 of the display module 2 includes the inorganic film layer, the inorganic film layer is weak, and is very easy to damage when stressed, and cracks as shown in fig. 3C occur, resulting in damage to the display module 2.

Based on this, under the condition that the distance between the shielding portion 110 and the display module 2 is not changed, in order to avoid the damage to the display module 2, the embodiment of the present application further provides a foldable display terminal 1, as shown in fig. 4A, the foldable display terminal 1 mainly includes the display module 2, a middle frame 3 (not shown in fig. 4A), a rear cover 4 (not shown in fig. 4A), a cover plate 5 and a protection assembly 100.

The display module 2, the middle frame 3, the rear cover 4 and the cover plate 5 can refer to the above description about the display module 2, the middle frame 3, the rear cover 4 and the cover plate 5, which is not repeated herein.

As shown in fig. 4B, the shield assembly 100 includes a shield portion 110 and a connecting portion 120 that are connected to and intersect with each other.

The shielding assembly 100 is disposed on two opposite sides of the rotating shaft 310.

The connecting portion 120 is located outside the display module 2 and connected to the hinge 310.

Illustratively, a groove is formed in the rotating shaft 310, and one end of the connecting portion 120, which is away from the shielding portion 110, is inserted into the groove, so that the connecting portion 120 is connected to the rotating shaft 310.

The shielding portion 110 extends to the light emitting side of the display module 2 and is located in the peripheral region 20. The shielding portion 110 has a gap between the portion of the peripheral circuit region 22 and the display module 2. The value range of the clearance is 0mm-1mm. For example, the gap may be 0.2mm, 0.36mm, 0.5mm, 0.7mm, or 0.9mm.

The peripheral region 20 in which the shielding portion 110 is located includes a package region 21 and a peripheral circuit region 22. Thus, the concentrated stress on the package region 21 of the display module 2 is relieved.

As shown in fig. 4C, the shielding portion 110 has a recessed area 111 facing the display module 2. The recessed region 111 is located in the peripheral region 20. The recessed region 111 is located in the peripheral region 20, so as to relieve the concentrated stress on the peripheral region 20 of the display module 2 and reduce the risk of damage to the display module 2.

In some embodiments, as shown in fig. 4C, the recessed region 111 is located in the encapsulation region 21 of the peripheral region 20. The recessed region 111 is located in the package region 21 near the edge of the peripheral circuit region 22. That is, the portion of the shielding portion 110 located at the encapsulation area 21 has the recessed area 111. When the folding display terminal 1 is in a folded state, the concentrated stress of the shielding part 110 on the display module 2 can be relieved, and the risk of damage to the display module 2 is reduced.

In other embodiments, as shown in fig. 4D, the recessed region 111 is near the edge of the peripheral circuit region 22 and overlaps with the package region 21 near the edge of the peripheral circuit region 22. That is, the recess region 111 is located in the package region 21. At this time, the projection of the recessed region 111 coincides with the peripheral circuit region 22 in the thickness direction Z of the folded display terminal 1.

Thus, when the foldable display terminal 1 is in the folded state, the partial shielding portion 110 located in the peripheral circuit region 22 contacts the display module 2, so that the partial shielding portion 110 located in the package region 21 is prevented from contacting the display module 2, and the package region 21 is prevented from being damaged due to concentrated stress.

In still other embodiments, as shown in fig. 4E, the recessed region 111 also extends to the peripheral circuit region 22. That is, the recessed region 111 is located in the package region 21, and a portion of the recessed region 111 is also located in the peripheral circuit region 22. The projection of the recessed region 111 is located at the package region 21 and a part of the peripheral circuit region 22 in the thickness direction Z of the folded display terminal 1.

Regarding the structure of the recessed region 111, as shown in fig. 4B, the recessed region 111 is an open groove. The open slot extends in a direction X perpendicular to the rotation shaft 310. That is, when the foldable display terminal 1 is in the folded state, the shielding portion 110 does not contact the encapsulation area 21 of the display module 2.

Illustratively, as shown in FIG. 4C, the connecting portion 120 serves as a sidewall of the open slot.

Alternatively, for example, as shown in fig. 4F, the open slot is located in the encapsulating region 21, and the wall of the open slot is the shielding portion 110.

The length h1 of the concave region 111 along the extending direction Y of the rotating shaft 310 is greater than 0mm and less than or equal to 2mm. For example, the length h1 of the recessed region 111 is 0.2mm, 0.3mm, 0.5mm, 0.8mm, 1.2mm, 1.3mm, 1.5mm, 1.6mm, or 1.9mm.

If the length h1 of the recessed area 111 is smaller, the shielding portion 110 cannot completely avoid the packaging area 21 of the display module 2, and when the foldable display terminal 1 is in the folded state, the shielding portion 110 may contact the packaging area 21 to generate stress on the display module 2, which may cause the display module 2 to be damaged.

Table 1 shows the length h1 of the different recessed regions 111, and the stress of the shielding portion 110 on the package region 21 of the display module 2.

TABLE 1

Fig. 5A shows the stress distribution of the shielding portion 110 to the display module 2 when the length h1 of the recessed region 111 is 0. Fig. 5B shows the stress distribution of the shielding portion 110 on the display module 2 when the length h1 of the recessed area 111 is 0.4 mm. Fig. 5C shows the stress distribution of the shielding portion 110 on the display module 2 when the length h1 of the recessed area 111 is 0.6 mm. Fig. 5D shows the stress distribution of the shielding portion 110 on the display module 2 when the length h1 of the recessed region 111 is 1mm.

As shown in fig. 5A to 5D, as the length h1 of the recessed region 111 increases, the stress of the shielding portion 110 on the encapsulation region 21 of the display module 2 gradually decreases. The existence of depressed area 111 can also be in folding state with folding display terminal 1, and the display module assembly 2 is transferred to peripheral circuit region 22 by encapsulation district 21 with the interference region of shielding portion 110, makes the concentrated stress that display module assembly 2 received reduce, consequently, sets up the concentrated stress that display module assembly 2 received can effectively be alleviated to depressed area 111 on shielding portion 110, reduces display module assembly 2's local stress concentration, reduces the damaged risk of display module assembly 2.

Along the extending direction Y of the rotating shaft 310, the length h2 of the shielding portion 110 in the interference area of the display module 2 is greater than 0mm and less than or equal to 2mm. For example, h2 is 0.2mm, 0.4mm, 0.6mm, 0.7mm, 0.9mm, 1mm, 1.3mm, 1.4mm, 1.65mm, 1.8mm, or 1.94mm. The larger h2 is, the larger the interference area between the shielding portion 110 and the display module 2 is, the more concentrated stress that the display module 2 receives can be relieved, and the more damaged risk of the display module 2 can be reduced. It is explained here that the interference area between the shielding portion 110 and the display module 2 is located in the packaging region 21, and it is only necessary to ensure that the shielding portion 110 does not extend to the display region 10.

In some embodiments, as shown in fig. 4E, the bottom of the recessed region 111 is planar.

The depth d1 of the recessed region 111 in the thickness direction Z of the folded display terminal 1 is less than or equal to 1.5mm. For example, the depth d1 of the recessed region 111 is 0.2mm, 0.46mm, 0.5mm, 0.8mm, 1mm, 1.3mm, or 1.4mm.

The depth d1 of the recessed area 111 is too large, so that the thickness of the shielding portion 110 with the recessed area 111 is too small, and the risk of fracture is increased, therefore, the thickness of the shielding portion 110 needs to be increased to avoid fracture of the shielding portion 110, which causes the too thick shielding portion 110 to affect the using effect of the foldable display terminal 1.

In other embodiments, as shown in FIG. 6A, the bottom of the recessed area 111 is curved. The stress of the shielding portion 110 on the display module 2 can be reduced only by ensuring that the depth d1 of the recessed region 111 is not more than 0.5mm.

Illustratively, the bottom of the recessed region 111 is a circular arc.

Alternatively, the bottom of the concave region 111 is concave-convex.

The embodiment of the present application does not limit this, and only needs that the thickness of the shielding portion 110 in the package region 21 is smaller than the thickness of the shielding portion 110 in the peripheral circuit region 22.

In some embodiments, as shown in fig. 6A, the top surface of the connecting portion 120 away from the display module 2 is higher than the top surface of the shielding portion 110 away from the display module 2.

The top surface of the connecting portion 120 away from the display module 2 is at most 0.5mm higher than the top surface of the shielding portion 110 away from the display module 2. For example, the height difference h3 between the top surface of the connecting portion 120 away from the display module 2 and the top surface of the shielding portion 110 away from the display module 2 is 0.08mm, 0.15mm, 0.27mm, 0.36mm, 0.43mm or 0.5mm. Therefore, the assembling process of the whole machine is more convenient, and the assembly of the protective component 100 is convenient.

Or, for example, as shown in fig. 6B, the top surface of the connecting portion 120 away from the display module 2 is flush with the top surface of the shielding portion 110 away from the display module 2. The folding display terminal 1 is more beautiful and nice in appearance.

In some embodiments, as shown in fig. 6C, the shield assembly 100 further includes a bumper portion 130. The buffer portion 130 covers at least the surface of the shielding portion 110 close to the display module 2.

Illustratively, the buffer portion 130 covers the surface of the shielding portion 110 close to the display module 2.

Or, for example, the buffer portion 130 covers a surface of the shielding portion 110 close to the display module 2 and a surface of the shielding portion 110 far from the display module 2.

Alternatively, the buffer portion 130 wraps around the periphery of the shielding portion 110.

The buffer portion 130 at least covers the surface of the shielding portion 110 close to the display module 2, so that the shielding portion 110 can effectively relieve the concentrated stress of the display module 2 when the foldable display terminal 1 is in a folded state.

The buffer portion 130 is disposed in the first and

second structures

321 and 322 and extends toward the first and

second structures

321 and 322 to block a gap between the first and

second structures

321 and 322 and the rotation shaft 310.

In some embodiments, as shown in fig. 6E, in the direction X from the rotation axis 310 to the first structural member 321, a width w1 of a portion of the protective assembly 100 above the display module 2 is smaller than a width w2 of the rotation axis 310.

Meanwhile, as shown in fig. 6F, the width w1 of the portion of the protective assembly 100 above the display module 2 should be smaller than the width w3 of the bending region 210. Thus, the shielding assembly 100 can shield the gap between the display module 2 and the rotating shaft 310, and the folding of the foldable display terminal 1 can be prevented from being affected.

In some embodiments, the bottom surface of the portion of the shielding portion 110 in the peripheral circuit region 22 is a curved surface. That is, the surface of the portion of the shielding portion 110 in the peripheral circuit region 22 close to the display module 2 is a curved surface.

Alternatively, as shown in fig. 7B, the bottom surface of the partial shielding section 110 in the peripheral circuit region 22 is a concave-convex surface. This is limited by the present application.

In this case, the distance from the point of the shielding portion 110 closest to the display module 2 should satisfy the range of the gap between the shielding portion 110 and the display module 2.

In some embodiments, as shown in fig. 8, the connection 120 includes a first portion 121 and a second portion 122.

The first portion 121 is disposed on a side of the second portion 122 close to the display module 2.

The first portion 121 is connected to the shielding portion 110 and the second portion 122, respectively, and the second portion 122 is connected to the rotation shaft 310.

The first portion 121 and the second portion 122 may be separately manufactured and then connected by a damascene process, or may be integrally manufactured. The embodiment of the application does not limit the method and can be reasonably set according to needs.

The material of the connecting portion 120 includes a rigid material, and may be, for example, metal or hard plastic, etc. The materials of the first portion 121 and the second portion 122 may be the same or different.
