Detailed Description
Embodiments of the present invention are further described below with reference to the accompanying drawings. The same or similar reference numbers in the drawings refer to the same or similar elements or elements having the same or similar functions throughout.
In addition, the embodiments of the present invention described below with reference to the drawings are exemplary only for explaining the embodiments of the present invention and are not to be construed as limiting the present invention.
Referring to fig. 1 and 2, a flexible display screen 10 according to an embodiment of the present invention includes a flexible display panel 12, a flexible substrate 14, and a hinge member 16. The flexible display panel 12 includes a front face 120 and a back face 122 that are opposite. The flexible substrate 14 is disposed on the back surface 122 to support the flexible display panel 12. The hinge part 16 is disposed in the flexible substrate 14 and extends from one side of the flexible substrate 14 to the other side, and the hinge part 16 includes a first hinge structure 160, a second hinge structure 161, and a third hinge structure 162 between the first hinge structure 160 and the second hinge structure 161, each hinge structure including a plurality of hinge units 163 sequentially connected one to another, each hinge unit 163 being capable of rotating with respect to an adjacent hinge unit and being maintained at a predetermined angle.
Specifically, the size of the flexible display panel 12 is consistent with the size of the flexible substrate 14, and the hinge part 16 is disposed on the entire side of the flexible substrate 14, and since the flexible substrate 14 is disposed on the back surface 122 of the flexible display panel 12 and the hinge part 16 is disposed on the entire side of the flexible substrate 14, the flexible display screen 10 is bent in the full screen range by bending of the hinge part 16.
Specifically, the first hinge structure 160 and the second hinge structure 161 are used to adjust the bending of the two ends of the flexible display screen 10, respectively. When the first hinge structure 160 and the second hinge structure 161 are linear and the third hinge structure 162 is curved, the corresponding flexible display screen 10 located above the first hinge structure 160 and the second hinge structure 161 can be used as two screens of split-screen display. When the hinge member 16 is bent, the flexible display 10 is folded for portability.
Referring to fig. 3, in some embodiments, each hinge structure further includes a plurality of connecting members 164 and a plurality of connecting shafts 165, each of the two connecting members 164 is located at two sides of the hinge unit 163 and can connect with adjacent hinge units 163, an end portion of the hinge unit 163 connected with the adjacent hinge unit 163 is defined as a connecting end 166, each connecting end 166 penetrates through the hinge unit 163 and is provided with a connecting shaft 165, and two ends of each connecting member 164 can be rotatably connected with the adjacent connecting shaft 165.
In this way, the hinge units 163 can rotate relative to the connecting piece 164, so that the two adjacent hinge units 164 can rotate relative to each other, and the hinge part 16 can support the flexible display panel 12 to rotate.
Referring to fig. 1 and 3, in some embodiments, two adjacent hinge units 164 are closely connected.
In some embodiments, the hinge element 163 is a cylindrical structure with both ends of the end face 163a being semicircular and a middle being rectangular. The connecting piece 164 is plate-shaped, the length of the connecting piece 164 is equal to the diameter of a semicircle, two ends of the connecting piece 164 are respectively connected with two connecting shafts 165 which are adjacent to two hinge monomers 163, and the central axis of the connecting shaft 165 coincides with the center of the semicircle. When the hinge units 163 are relatively rotated, the distance between the two connection shafts 165 is maintained constant while the sides of the two hinge units 163 are always in contact.
In this way, when the hinge member 16 is bent, a large friction force is generated between the two adjacent hinge units 164, and the two adjacent hinge units 164 are not easy to rotate relatively under the action of the friction force, so that the relative rotation angle between the two adjacent hinge units 164 is further kept at a predetermined bending angle when the flexible display screen 10 is bent.
In some embodiments, two adjacent hinge elements 164 are spaced apart with a preload between the connecting shaft 165 and the connecting member 164 and a preload between the connecting shaft 165 and the hinge elements 163.
In this way, there is a large friction force between the connection shaft 165 and the connection member 164 and it is not easy to rotate relatively, and at the same time there is a large friction force between the connection shaft 165 and the hinge unit 163 and it is not easy to rotate relatively, so that when the flexible display screen 10 is bent, a relative rotation angle between two adjacent hinge units 164 can be maintained, and thus, when the flexible display screen 10 is bent, a predetermined bending angle can be maintained.
Referring to fig. 3, in some embodiments, the first hinge structure 160 and the second hinge structure 161 respectively include a connection line 167 penetrating the plurality of hinge units 163 along a connecting direction of the plurality of hinge units 163, the connection line 167 includes a fixed end 168 and a movable end 169 located on the same side of the first hinge structure 160 and the same side of the second hinge structure 161, and the connection line 167 is used for adjusting the flatness of the first hinge structure 160 and the second hinge structure 161.
Specifically, the movable end 169 is pulled tightly to make the connecting line 167 pass through the first hinge structure 160 and the second hinge structure 161 to be shortest, so that the first hinge structure 160 and the second hinge structure 161 are arranged in a straight line. In this way, the flexible display panel 12 above the first hinge structure 160 and the second hinge structure 161 can be adjusted to be a plane under the action of the connecting wire 167, so that the flexible display screen 10 can have a better split-screen display effect in the area of the first hinge structure 160 and the area of the second hinge structure 161.
In some embodiments, the fixed end 168 is secured to the hinge cell 163 at the end of the hinge structure and the movable end 169 is disposed outside the hinge structure.
Referring to fig. 3 and fig. 4, in some embodiments, along a direction in which the plurality of hinge units 163 are connected sequentially, the first hinge structure 160 and the second hinge structure 161 are provided with a connection hole 170 penetrating the hinge units 163, and the connection wire 167 penetrates the connection hole 170 and connects the hinge units of the first hinge structure 160 and the second hinge structure 161 in series.
In this way, the hinge structures are connected in series through the connection holes 170 and the connection lines 167 provided on the hinge units 163, so that the bending angle of the hinge structures can be adjusted through the connection lines 167.
In some embodiments, there is only one connection hole 170 per hinge element 163, and the connection hole 170 is located through the middle of the hinge element 163 (not shown). In this way, when the first hinge structure 160 and the second hinge structure 161 are linear, the length of the connection line 167 passing through the first hinge structure 160 and the second hinge structure 161 is minimized.
Referring to fig. 4, in some embodiments, there are two connection holes 170 on each hinge unit 163, and the two connection holes 170 are symmetrically disposed with respect to the middle of the hinge unit 163. Specifically, the two connection holes 170 on the first hinge structure 160 may be distributed in the upper and lower halves (viewed in the direction of the vertical connection shaft 165)/the front and rear halves (viewed in the direction of the connection shaft 165) of the first hinge structure 160, and the two connection holes 170 on the second hinge structure 161 may be distributed in the upper and lower halves (viewed in the direction of the vertical connection shaft 165)/the front and rear halves (viewed in the direction of the connection shaft 165) of the first hinge structure 160.
In addition, the distance between the two connection holes 170 is set as large as possible on the premise of satisfying the processing process and strength of the connection holes 170. In this way, the first hinge structure 160 and the second hinge structure 161 are easily adjusted by the connection line 167.
In some embodiments, the flexible substrate 14 is provided with a clamping groove 171 between the first hinge structure 160 and the third hinge structure 162 and between the second hinge structure 161 and the third hinge structure 162, respectively, and the movable end 169 is exposed from the flexible substrate 14 and can be selectively clamped at opposite ends of the clamping groove 171.
Specifically, when the movable end 169 is clamped at one end of the clamping groove 171 near the first hinge structure 160, the connecting wire 167 is in a loose state, and at this time, the first hinge structure 160 can be bent, and the flexible display screen 10 can be curled. When the movable end 169 is located at one end of the clamping groove 171 away from the first hinge structure 160, the connecting wire 167 is in a tensioned state, and the first hinge structure 160 is in a straight line shape under the action of the tensioning force of the connecting wire 167, and at this time, the flexible display screen 10 is used for split-screen display. In this way, the bending angle of the flexible display 10 can be adjusted by disposing the movable end 169 at different positions of the catching groove 171.
Referring to fig. 1 and 3 together, in some embodiments, the flexible display 10 further includes an adjusting member 172 connected to the movable end 169, the flexible substrate 14 has a slot 171 between the first hinge structure 160 and the third hinge structure 162 and between the second hinge structure 161 and the third hinge structure 162, and the adjusting member 172 is received in the slot 171 and exposed from the flexible substrate 14 and can be selectively clamped at opposite ends of the slot 171.
Thus, the movable end 169 can be adjusted by adjusting the end of the adjusting member 172 exposed outside the flexible substrate 14, so that the adjusting of the connecting wire 167 is facilitated, and the adjusting member 172 is arranged to enable the user to adjust the connecting wire 167 more easily and the user experience is better.
In some embodiments, the depth of the clamping groove 171 is greater than the distance between the center of the connecting hole 170 penetrated by the movable end 169 and the end face 163a of the hinge unit 163 along the central axis direction of the connecting shaft 165, the adjusting member 172 is in a round rod shape, two ends of the adjusting member 172 are clamped in the clamping groove 171, one end of the adjusting member 172 is exposed from the flexible substrate 14, and the movable end 169 is connected between two ends of the adjusting member 172.
Referring to fig. 1, in some embodiments, the first hinge structure 160 is directly hinged to the third hinge structure 162, and the second hinge structure 161 is directly hinged to the third hinge structure 162.
In this way, the first hinge structure 160, the second hinge structure 161 and the third hinge structure 162 are connected to form one hinge structure, so that the hinge part 16 is convenient to support the whole flexible display screen 10, the flexible display screen 10 is convenient to bend in the full screen range, and meanwhile, the whole hinge structure is more stable than a plurality of separated hinge structures, and has a better bending effect.
In some embodiments, the first hinge structure 160 and the third hinge structure 162 are separated from each other, and the second hinge structure 161 and the third hinge structure 162 are separated from each other.
Thus, since the first, second and third hinge structures 160, 161 and 162 are different from each other, they are separated from each other to facilitate the manufacture and installation of the first, second and third hinge structures 160, 161 and 162, respectively.
In some embodiments, the flexible substrate 14 between the first hinge structure 160 and the third hinge structure 162 is hinged to the first hinge structure 160, and the flexible substrate 14 between the first hinge structure 160 and the third hinge structure 162 is hinged to the third hinge structure 162.
In this way, the first hinge structure 160 and the third hinge structure 162 are fixed in the flexible substrate 14, so that the first hinge structure 160 and the third hinge structure 162 can be prevented from sliding relative to the flexible substrate 14 when the flexible display 10 is bent, and the bending effect of the flexible display 10 can be further prevented. Meanwhile, the first hinge structure 160 and the third hinge structure 162 are hinged to the flexible substrate 14 respectively, so that the flexible display screen 10 has a better bending effect at the connection position of the first hinge structure 160 and the third hinge structure 162.
In some embodiments, the flexible substrate 14 between the second hinge structure 161 and the third hinge structure 162 is hinged to the second hinge structure 161, and the flexible substrate 14 between the second hinge structure 161 and the third hinge structure 162 is hinged to the third hinge structure 162.
In this way, the second hinge structure 161 and the third hinge structure 162 are conveniently fixed in the flexible substrate 14, so that when the flexible display screen 10 is bent, the second hinge structure 161 and the third hinge structure 162 are prevented from sliding relatively to the flexible substrate 14, and the bending effect of the flexible display screen 10 is further prevented from being affected. Meanwhile, the second hinge structure 161 and the third hinge structure 162 are hinged to the flexible substrate 14 respectively, so that the flexible display screen 10 has a better bending effect at the connection position of the second hinge structure 161 and the third hinge structure 162.
Referring to fig. 1, 5, 6 and 7, in some embodiments, the hinge assembly 10 further includes two connection hinge bodies 173 disposed in the flexible substrate 14, the first hinge structure 160 is connected to the third hinge structure 162 through the connection hinge bodies 173, and the second hinge structure 161 is connected to the third hinge structure 162 through the connection hinge bodies 173.
Specifically, the shape of the connection hinge body 173 is similar to that of the hinge unit 163, the end face 173a of the connection hinge body 173 is larger than the end face 163a of the hinge unit 163, hinge connection shafts 174 are also provided in both end portions of the connection hinge body 173, and the connection hinge body 173 is connected to the adjacent hinge unit 163 through the hinge connection bodies 175. In this manner, the first hinge structure 160, the second hinge structure 162, and the third hinge structure 163 are connected to form one hinge structure, thereby facilitating the hinge member 16 to support the entire flexible display 10 and facilitating the flexible display 10 to bend over a full screen range.
In some embodiments, the central axis of the hinge connection shaft 174 coincides with the center of the semicircle, and the length of the hinge connection 175 is equal to the sum of the radius of the semicircle connection hinge body 173 and the radius of the semicircle hinge unit 163. When the hinge body 163 and the connection hinge body 173 relatively rotate, the distance between the connection shaft 165 and the hinge connection shaft 174 remains unchanged, and the hinge body 163 and the side surface of the connection hinge body 173 remain in contact all the time, so that the hinge body 163 and the connection hinge body 173 can maintain a relative rotation angle.
In some embodiments, the connection hinge body 173 is provided with a clamping groove 171 and a through hole 176 communicating with the clamping groove 171. The flexible display screen 10 further includes an adjustment member 172, the adjustment member 172 being received in the clamping groove 171 and exposed from the flexible substrate 14 and being capable of being selectively clamped at opposite ends of the clamping groove 171. The movable end 169 passes through the through hole 176 and is connected to the regulator 172.
In this way, the movable end 169 may be inserted into the clamping groove 171 through the through hole 176, and the clamping groove 171 is disposed in the connecting hinge body 173, so that the structure of the hinge member 16 is more compact.
Specifically, in the hinge member 16, the depth 171a of the catching groove 171 is larger than the distance 176a between the through hole 176 and the end surface 173a of the connection hinge body 173, and the through hole 176 coincides with the axis of the connection hole 170. In this manner, the movable end 169 is conveniently disposed within the clamping groove 171 through the through hole 176.
In some embodiments, the clamping groove 171 includes a first clamping section 178 and a second clamping section 179 that communicates with the first clamping section 178 and forms an angle.
Specifically, the first engaging section 178 and the second engaging section 179 are disposed at an acute angle, so that the adjusting member 172 is conveniently engaged with the slot 171.
In some embodiments, the first engagement section 178 extends in a direction that coincides with the axial direction of the connection hole 170.
In some embodiments, the number of hinge members 16 is two, with two hinge members 16 being disposed at opposite ends of the flexible substrate 14, respectively.
Thus, both ends of the flexible display screen 10 can be adjusted, and the problem that the rotation angles of both ends of the flexible display screen 10 are inconsistent due to the fact that only one end can be adjusted is avoided.
In some embodiments, a mounting slot 140 is formed in one side of the flexible substrate 14 and the hinge member 16 is disposed within the mounting slot 140.
In this manner, the hinge member 16 is conveniently snapped into the mounting slot 140. Specifically, the shape of the mounting groove 140 is consistent with the shape of the hinge member 16, so that the hinge member 16 is clamped in the mounting groove 140, thereby ensuring that the hinge member 16 does not slide in the mounting groove 140 to affect the curling effect of the flexible display 10 when the flexible display 10 is bent.

The housing of the flexible display device described above is also designed in a structure that is bendable within the scope of the flexible display screen 10 so that the flexible display screen 10 is bendable within the full screen scope.
