For a better understanding of the technical solutions and technical effects of the present application, specific embodiments will be described in detail below with reference to the accompanying drawings.
Referring to fig. 1, a cross-sectional view of a display device according to an embodiment of the present application includes:
the display module comprises a flexible substrate 1, wherein the flexible substrate 1 comprises a first sub-part 11, a second sub-part 12 and a bending part 13 for connecting the first sub-part 11 and the second sub-part 12, and the second sub-part 12 is positioned at one side of the first sub-part 11 away from the light emitting surface of the display module. The first electronic structure 2 connected to the second sub-portion 12, the first electronic structure 2 including a flexible circuit board 22 and a first chip 21. Therefore, the first electronic structure 2 is arranged on one side, which is away from the light emitting surface of the display module, of the first electronic structure through the bending part 13, so that the frame width of the non-display area of the display device can be reduced.
The first electronic structure 2 is located at one side of the first sub-portion 11 away from the light emitting surface of the display module, and the first supporting member 3 is located between the first electronic structure 2 and the first sub-portion 11, where the orthographic projection of the first supporting member 3 on the surface of the light emitting surface of the display module at least partially overlaps with the orthographic projection of the first chip 21 on the surface of the light emitting surface of the display module.

Optionally, the rigidity of the first supporting member 3 is greater than a preset threshold value, so that the film layer in the display module can be better protected from being extruded by the first electronic structure 2, and the inner film layer of the display module is prevented from generating unrecoverable inner deformation. It should be noted that the stiffness of the first support member 3 is not specifically limited in this embodiment of the present application, and may be specifically set by those skilled in the art according to actual situations. Alternatively, the material of the first support 3 may include a stainless steel material (SUS, steel Used Stainless) so that the rigidity is strong and an effective protection function can be achieved.
In an embodiment of the present application, the flexible substrate 1 may include various flexible or bendable materials, for example, polymer resins such as Polyethersulfone (PES), polyacrylate (PAR), polyetherimide (PEI), polyethylene naphthalate (Polyethylene naphthalate, PEN), polyethylene terephthalate (Polyethylene terephthalate, PET), polyphenylene sulfide (Polyphenylene sulfide, PPS), polyarylate, polyimide (PI), polycarbonate (PC), or cellulose acetate propionate (Cellulose Acetate Propionate, CAP), and the display module including the flexible substrate 1 facilitates realization of various new display forms such as a folding screen, a curling screen, etc., the operation scene of the folding screen, the curling screen, etc., including the display in a partially folded state.
In a possible implementation manner, referring to fig. 2, a cross-sectional view of another display device provided by an embodiment of the present application may further include an adhesive tape 4 located between the first sub-portion 11 and the first chip 21, where the front projection of the first chip 21 on the light-emitting surface of the display module overlaps at least partially with the front projection of the adhesive tape 4 on the light-emitting surface of the display module.
That is, in the embodiment of the present application, the adhesive tape 4 may be further provided to protect the display module and the first chip 21, and on the basis of the first supporting member 3, the adhesive tape is provided to further reduce extrusion caused to the display module, so as to avoid the unrecoverable internal deformation and the imprint of the film layer inside the display module caused by extrusion, which affects the display effect of the display module. In addition, the orthographic projection of the first chip 21 on the surface of the light emitting surface of the display module is at least partially overlapped with the orthographic projection of the adhesive tape 4 on the surface of the light emitting surface of the display module, that is, the adhesive tape 4 is arranged at the position corresponding to the first chip 21, so that the further protection effect on the first chip 21 can be achieved, and the damage of the first chip 21 possibly caused by overlarge pressure when the first chip 21 is attached is avoided.
Optionally, the adhesive tape 4 provided in the embodiment of the present application may specifically include a shielding adhesive tape, where the shielding adhesive tape is a metal foil or conductive cloth with a highly conductive back adhesive, and the conductive back adhesive and the conductive base material form a complete conductor, and may be adhered to any metal surface to complete electrical lap joint and electrical sealing of the gap. The shielding conductive adhesive tape is economical and practical, and the use of the shielding material is convenient, so that the manufacturing cost of the display device provided by the embodiment of the application is reduced by using the shielding adhesive tape.
In a possible implementation manner, referring to fig. 3, a display device provided by an embodiment of the present application may further include: the first support 3 is provided with a first groove 5 in a region corresponding to one side of the adhesive tape 4, and the adhesive tape 4 is arranged in the first groove 5.
The first groove 5 can be arranged for attaching the adhesive tape 4, so that the first chip 21 is better protected by the adhesive tape 4, the extrusion of the film layer of the display module is reduced, and the overall thickness of the display device can be reduced.
In a possible implementation manner, referring to fig. 3, in a cross-sectional view of still another display device provided in this embodiment of the present application, the depth of the first groove 5 may be less than or equal to the thickness of the adhesive tape 4, so that the adhesive tape 4 may be effectively attached to the surface of the first chip 21, and the strength of the first support member 3 is reduced due to the too deep depth of the first groove 5, which results in a reduced protection effect of the first support member 3.
In a possible implementation manner, referring to fig. 4, a cross-sectional view of another display device provided in an embodiment of the present application may further include: the first supporting member 3 may be provided with a second groove 6 corresponding to the region of the electronic component on the flexible circuit board 22, that is, may function to accommodate the electronic component on the flexible circuit board 22 through the second groove 6, so as to reduce the overall thickness of the display device.
Optionally, in order to further protect the internal film layer of the display module and protect the electronic component, the adhesive tape 4 may be disposed in the second groove 6 by dispersing the pressure of the flexible circuit board during extrusion adhesion, as shown in fig. 5, so as to avoid the internal deformation of the film layer inside the display module, which is not recovered and the generation of an imprint, or the damage of the electronic component caused by extrusion.
In a possible implementation manner, referring to fig. 6, in a top view of the first support member 3 provided in this embodiment of the present application, the first support member 3 may include a non-hollowed-out area 31 and a hollowed-out area 32, and because the first support member 3 is harder and stronger, when the first support member 3 is attached to the display module, the pressure during attaching easily causes deformation of the display module, and part of the first support member 3 is hollowed-out, so that the first support member 3 may be softened and be convenient for attaching, thereby avoiding deformation of each film layer of the display module caused by the pressure during attaching.
In a possible implementation manner, the front projection of the electronic component on the first electronic structure 2 provided by the embodiment of the present application on the surface of the light emitting surface of the display module is not overlapped with the front projection of the hollowed-out area 32 on the surface of the light emitting surface of the display module.
That is, in the embodiment of the present application, since the hollowed-out area 32 is softer and has insufficient rigidity, when the electronic components are attached, the electronic components cannot withstand the larger pressure generated during attachment, so that the embodiment of the present application can set the electronic components in the area corresponding to the non-hollowed-out area 31, so as to ensure that the first support member can protect the electronic components on the first electronic structure 2, and can protect each film layer in the display module, thereby avoiding deformation of each film layer of the display module caused by the pressure during attachment.
In a possible implementation manner, the area of the bonding area between the first electronic structure 2 and the first support 3 provided in the embodiment of the present application is smaller than or equal to the area of the non-hollowed-out area 31. That is, in order to make the first supporting member 3 have enough bonding space in the non-hollow area 31, the area of the non-hollow area 31 may be set larger in the embodiment of the present application, that is, the area of the non-hollow area 31 is greater than or equal to the bonding area of the first electronic structure 2 and the first supporting member 3.
In one possible implementation, since the hollow area 32 is provided to soften the first support member 3, that is, the strength of the first support member 3 is reduced by the hollow area 32, the area of the hollow area 32 is not too large to ensure the strength of the first support member 3, so in the embodiment of the present application, the area of the non-hollow area 31 may be larger than or equal to the area of the hollow area 32.
In one possible implementation manner, referring to fig. 7, a cross-sectional view of another display device provided in an embodiment of the present application may further include: the front projection of the first adhesive film 7 between the first sub-portion 11 and the first supporting member 3 on the surface of the light emitting surface of the display module is included in the front projection of the first adhesive film 7 on the surface of the light emitting surface of the display module.
That is, in the embodiment of the present application, the first adhesive film 7 may be set larger, so that the area of the first adhesive film 7 is larger than the area of the first support member 3, so that when the first support member 3 is attached, the first adhesive film 7 may protect the display module, and prevent the edge of the first support member 3 from being sharp and damaging the display module during attachment. Meanwhile, the area of the first adhesive film 7 is larger, and the full fit between the first adhesive film 7 and the first supporting piece 3 can be better realized.
In one possible implementation, referring to fig. 1-5 and 7, the first chip 21 provided in the embodiment of the present application may be disposed on a side of the second sub-portion 12 away from the first sub-portion 11.
In general, the display device with the first chip 21 located on the side of the second sub-portion 12 away from the first sub-portion 11 is adopted, so that the flexible circuit board 22 and the display module are closely attached together, which saves space and makes the display device lighter and thinner. Along with the trend of light and thin mobile phones in the market, the display device is generally applied to mobile phones.
In one possible implementation, referring to fig. 8, a schematic cross-sectional view of another display device according to an embodiment of the present application is shown, where the second sub-portion 12 of the flexible substrate 1 is connected to the flexible circuit board 22 through the Chip On Film 8 (COF), and the first Chip 21 is located between the first support 3 and the Chip On Film 8.
The flip chip film 8 refers to a soft additional circuit board without a packaged chip, and the chip can be packaged on the soft additional circuit board.
In general, since the space requirement of the display device is not as high as that of the mobile phone for other terminals such as watches, vehicle-mounted devices and the like, but the reliability requirement of the display device is higher, and the interface of the first chip 21 is generally arranged on one side of the flip-chip film 8 close to the first support member 3 when leaving the factory, in order to reduce the modification of the first chip 21, ensure the reliability and reduce the manufacturing cost, the first chip 21 can be arranged between the first support member 3 and the flip-chip film 8.

The first film layer 10 located on one side of the ultra-clean foam assembly 9 away from the first adhesive film 7 can also play a role in protecting the film layer of the display module. The second adhesive film 101 is located on one side of the first film layer 10 away from the ultra-clean foam component 9, so as to facilitate the adhesion with the display layer 102, and the display layer 102 is located on one side of the second adhesive film 101 away from the first film layer 10, and the display layer 102 can perform luminous display of the display device. The third adhesive film 104 is located on the side of the first sub-portion 11 away from the display layer 102, so as to facilitate the adhesion between the third adhesive film 104 and the cover plate 105 located on the side of the third adhesive film 104 away from the display layer 102.
