Abstract

Provided are a support plate, a display screen, and an electronic device. The support plate includes a first board and a second board. The first board and the second board are arranged back to back, and the first board is configured to be attached to a display panel. The support plate includes a bending area, and the support plate is configured to bend in the bending area along a preset axial line L. First strip-shaped slots are formed on the first board, and second strip-shaped slots distributed in an array at intervals along the axial line L are formed on the second board. The first strip-shaped slots are continuously provided along the axial line L and extend through the first board to form a unified edge structure.

First claim

the bending area is provided with a hollowed-out structure, the hollowed-out structure comprises a plurality of through grooves, and the plurality of through grooves are distributed in an array in a direction perpendicular to the axial line L; and
each through groove of the plurality of through grooves comprises one first strip-shaped slot and N second strip-shaped slots, and N is a positive integer greater than 1, wherein for each through groove:
the first strip-shaped slot and each of the second strip-shaped slots are all formed in parallel with the axial line L, and projections of center lines of the N second strip-shaped slots coincide with a projection of a center line of the first strip-shaped slot along a line that is parallel to the axial line L;
the first strip-shaped slot is formed on the first board and extends toward the second board by a depth, and the first strip-shaped slot is continuously provided along the axial line L and extends through the first board;
the N second strip-shaped slots are formed on the second board, extend toward the first board to a bottom of the first strip-shaped slot, and are in communication with the first strip-shaped slot; and
a length of the N second strip-shaped slots is less than a width of the support plate along the axial line L, and the N second strip-shaped slots are distributed in an array at intervals along the axial line L.

2 . The support plate according to claim 1 , wherein for each through groove: a depth of the N second strip-shaped slots is greater than a depth of the first strip-shaped slot.

3 . The support plate according to claim 1 , wherein for each through groove: the first strip-shaped slot is a structure with a constant width.

4 . The support plate according to claim 1 , wherein for each through groove: each second strip-shaped slot comprises a first slot segment and second slot segments located on two ends of the first slot segment, and a width of each of the second slot segments is greater than a width of the first slot segment.

5 . The support plate according to claim 4 , wherein the width of each second slot segment is greater than the width of the corresponding first strip-shaped slot, and the width of each first slot segment is equal to the width of the corresponding first strip-shaped slot.

6 . The support plate according to claim 1 , wherein two ends of each second strip-shaped slot are round-cornered structures.

7 . The support plate according to claim 1 , wherein each through groove is filled with a flexible medium, the flexible medium forms a first filling plane in the first strip-shaped slot and a second filling plane in the N second strip-shaped slots, the first filling plane and the first board are located in a same plane, and the second filling plane and the second board are located in a same plane.

8 . The support plate according to claim 7 , wherein the flexible medium is liquid silicone rubber.

9 . The support plate according to claim 1 , wherein a material of the support plate comprises any one of a TA4 titanium alloy, stainless steel or high-modulus polyvinyl alcohol PVA fiber.

10 . A display screen, comprising:
a cover plate, a display panel, and a support plate; wherein the display panel is attached to a first board of the support plate through an optically clear adhesive; and wherein the cover plate is attached to a side of the display panel facing away from the support plate through the optically clear adhesive; and wherein the support plate comprises the first board and a second board, the first board and the second board are arranged back to back, and the first board is configured to be attached to the display panel; wherein the support plate comprises a bending area, and the support plate is configured to bend in the bending area along a preset axial line L; wherein the bending area is provided with a hollowed-out structure, the hollowed-out structure comprises a plurality of through grooves, and the plurality of through grooves are distributed in an array in a direction perpendicular to the axial line L; and wherein each through groove of the plurality of through grooves comprises one first strip-shaped slot and N second strip-shaped slots, and N is a positive integer greater than 1, wherein for each through groove:
the first strip-shaped slot and each of the second strip-shaped slots are all formed in parallel with the axial line L, and projections of center lines of the N second strip-shaped slots coincide with a projection of a center line of the first strip-shaped slot along a line that is parallel to the axial line L;
the first strip-shaped slot is formed on the first board and extends toward the second board by a depth, and the first strip-shaped slot is continuously provided along the axial line L and extends through the first board;
the N second strip-shaped slots are formed on the second board, extend toward the first board to a bottom of the first strip-shaped slot, and are in communication with the first strip-shaped slot; and
a length of the N second strip-shaped slots is less than a width of the support plate along the axial line L, and the N second strip-shaped slots are distributed in an array at intervals along the axial line L.

11 . The display screen according to claim 10 , wherein for each through groove: a depth of the N second strip-shaped slots is greater than a depth of the first strip-shaped slot.

12 . The display screen according to claim 10 , wherein for each through groove: the first strip-shaped slot is a structure with a constant width.

13 . The display screen according to claim 10 , wherein for each through groove: each second strip-shaped slot comprises a first slot segment and second slot segments located on two ends of the first slot segment, and a width of each of the second slot segments is greater than a width of the first slot segment.
