In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. And the embodiments and features of the embodiments may be combined with each other without conflict. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention without any inventive step, are within the scope of protection of the invention.
Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention belongs. The use of "first," "second," and similar terms in the present application do not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect.
It should be noted that the sizes and shapes of the various figures in the drawings are not to scale, but are merely intended to illustrate the present disclosure. And the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.
Generally, a touch substrate capable of performing a touch function is generally provided with a touch electrode, so that the touch substrate can have a touch input function, allowing a user to directly input information by using a finger or a stylus, and thus can replace a mouse or a keyboard. In order to enable the display device to realize a touch function, a touch substrate is generally combined with a display panel in the display device.
With the development of display technology, the comprehensive screen has a larger screen occupation ratio and an ultra-narrow frame, and compared with a common display screen, the comprehensive screen can greatly improve the visual effect of a viewer, thereby receiving wide attention. Generally, in order to increase the screen occupation ratio of a display device (e.g., a mobile phone), the area of the lower bezel can be reduced. In a scheme of increasing the screen occupation ratio with respect to the area of the lower frame, the display panel is generally configured as a flexible display panel, so that a portion of the flexible substrate of the flexible display panel, which is located at the position of the lower frame, is bent to the backlight side of the display area, so as to reduce the width of the lower frame. And then the part bent to the backlight side of the display panel is bound with the driving chip.
As shown in fig. 1, the display device may include: the display device comprises a flexible display panel 1, a touch substrate 2 located on the light-emitting side of the flexible display panel 1, a first bonding layer 3 located between the flexible display panel 1 and the touch substrate 2, a protective cover plate 4 located on one side, away from the flexible display panel 1, of the touch substrate 2, and a second bonding layer 5 and a touch flexible circuit board 6 located between the touch substrate 2 and the protective cover plate 4. The touch substrate 2 has a bonding area T1, and the touch flexible circuit board 6 is electrically connected to the bonding area T1. In the manufacturing process of the display device, generally, after the flexible display panel 1 and the touch substrate 2 are formed, the touch substrate 2 and the flexible display panel 1 are attached to each other through the first adhesive layer 3. And then, the touch substrate 2 and the protective cover plate 4 are bonded through the second adhesive layer 5.
In the manufacturing process of the display device, the Bonding area T1 of the touch substrate 2 and the touch flexible circuit board 6 need to be bonded (Bonding) so as to be electrically connected to each other. Because the thickness of the film layer of the touch substrate 2 is small (less than 0.05mm), the binding width is small, and the strength is weak. In practical applications, the touch flexible circuit board 6 needs to be bent to the backlight side of the display panel for fixing. However, when the touch flexible circuit board 6 is bent, the circuit on the touch substrate 2 may be easily broken due to the concentration of the pulling stress of the touch flexible circuit board 6. And, due to the existence of the first adhesive layer 3, a gap d1 is formed between the flexible display panel 1 and the touch substrate 2. When the second adhesive layer 5 is attached to the touch flexible circuit board 6 in the binding region T1, the binding region T1 is easily bent by force, which may cause a risk of disconnection in the binding region T1.
In view of this, embodiments of the present invention provide a display device, which is used to reduce the risk of the bonding region being bent and broken, and improve the reliability of the display device.
An embodiment of the present invention provides a display device, as shown in fig. 2, which may include: the flexible display panel 100, the touch substrate 200 located at the light exit side of the flexible display panel 100, the first adhesive layer 300 located between the flexible display panel 100 and the touch substrate 200, and the support layer 400 filled in the gap d1 between the touch substrate 200 and the flexible display panel 100. Among them, the flexible display panel 100 includes: the flexible substrate 110, the flexible substrate 110 includes a display area a1, a step area a2 and a bending area A3, which are sequentially arranged. The touch substrate 200 includes an effective touch area T2 and a binding area T1, and the effective touch area T2 covers the display area a 1. The orthographic projection of the support layer 400 on the flexible substrate 110 at least covers the facing area Z of the binding area T1 and the step area a 2.
According to the display device provided by the embodiment of the invention, the flexible display panel and the touch substrate are combined through the first bonding layer, and the effective touch area covers the display area, so that the display device can realize a touch function. And the supporting layer is filled in the gap between the touch substrate and the flexible display panel, and the orthographic projection of the supporting layer on the flexible substrate at least covers the right area between the binding area and the step area, so that the gap between the touch substrate and the flexible display panel can be filled, the strength of the binding area can be improved, and the risk of line breakage caused by bending can be reduced.
In particular implementation, in the embodiment of the present invention, the display area of the flexible substrate may include a plurality of pixel units, each pixel unit including a plurality of sub-pixels. Illustratively, the pixel unit may include a red sub-pixel, a green sub-pixel, and a blue sub-pixel, so that color mixing may be performed by red, green, and blue to realize a color display. Alternatively, the pixel unit may also include a red sub-pixel, a green sub-pixel, a blue sub-pixel, and a white sub-pixel, so that color display may be realized by performing color mixing of red, green, blue, and white. Of course, in practical applications, the light emitting color of the sub-pixels in the pixel unit may be determined according to practical application environments, and is not limited herein.
In an embodiment of the present invention, the sub-pixel may include an electroluminescent Diode located on a substrate of the flexible substrate and a driving circuit for driving the electroluminescent Diode to emit Light. The electroluminescent diode comprises an anode, a light-emitting layer and a cathode which are arranged in a laminated mode. Further, the electroluminescent diode may include: at least one of an OLED and a QLED. In addition, the general driving circuit may include a plurality of transistors such as a driving transistor and a switching transistor, and a storage capacitor, and the specific structure and the operation principle thereof may be the same as those in the prior art, which is not described herein again.
In practical implementation, in the embodiment of the invention, as shown in fig. 2, the film layer 120 on the display substrate 110 may have film layers such as an electroluminescent diode, a driving circuit for driving the electroluminescent diode to emit light, and an encapsulation film. Of course, these layers may be substantially the same as those in the related art, and are not described in detail herein.
It should be noted that, in the embodiment of the present invention, there are some Dummy (Dummy) areas around the display area a1, and the Dummy areas can be used as buffer areas for the alignment and the like of part of the film layers (e.g. the first adhesive layer 300). Of course, in practical applications, the virtual area may also be substantially the same as that in the related art, and is not described herein again.
In an embodiment of the invention, the effective touch area of the touch substrate may include a plurality of touch electrodes. For example, the touch electrode may be a mutual capacitance electrode, so that the mutual capacitance technology may be combined with the display technology, so that the display device implements a touch function by using the mutual capacitance technology. The touch electrode can also be a self-capacitance electrode, so that the self-capacitance technology and the display technology can be combined, and the display device can realize the touch function by adopting the self-capacitance technology.
In specific implementation, in the embodiment of the present invention, as shown in fig. 2 and fig. 3, the display device may further include: the touch flexible circuit board 210 is positioned on one side of the touch substrate 200 away from the flexible display panel 100; and the touch flexible circuit board 210 is electrically connected with the bonding area T1. Illustratively, the bonding area of the touch substrate includes a plurality of touch bonding terminals (PADs) to be electrically connected with the touch flexible circuit board 210 through the touch bonding terminals. Therefore, signals output by the touch flexible circuit board 210 can be input and output to and from the touch electrodes through the touch binding terminals, and sensing signals of the touch electrodes are transmitted to the touch flexible circuit board 210 through the touch binding terminals (PAD).
In specific implementation, in the embodiment of the present invention, as shown in fig. 3, the display device may further include: the protective cover plate 500 is positioned on one side of the touch substrate 200, which is far away from the flexible substrate 110, and the second adhesive layer 600 is positioned between the protective cover plate 500 and the touch substrate 200; wherein, the second adhesive layer 600 covers the touch substrate 200. In this way, by covering the touch substrate 200 with the second adhesive layer 600, the second adhesive layer 600 can be adhered to the effective touch region T2 of the touch substrate 200, and the second adhesive layer 600 also extends above the bonding region T1 of the touch substrate 200, so that the second adhesive layer 600 also covers the bonding region T1 of the touch substrate 200, and thus the touch flexible circuit board 210 in the bonding region T1 can be stuck by the second adhesive layer 600, the bending and upward deformation amplitude of the touch flexible circuit board 210 can be reduced, the bending and downward deformation amplitude of the touch flexible circuit board 210 can be reduced, and the wire breakage risk of the bonding region T1 when the touch flexible circuit board 210 is bent can be further reduced.
It should be noted that, in the manufacturing process, due to the arrangement of the supporting layer 400 in the present invention, when the second adhesive layer 600 is attached to the touch flexible circuit board 210 in the bonding area T1, the stressed bending of the bonding area T1 can be reduced due to the function of the supporting layer 400, so as to reduce the risk of wire breakage in the bonding area T1. Moreover, due to the function of the supporting layer 400, when the second adhesive layer 600 is attached to the touch flexible circuit board 210 in the bonding area T1, the bonding area T1 may also be pressed with a proper force, so that the second adhesive layer 600 and the touch flexible circuit board 210 in the bonding area T1 may be completely bonded, and the bonding is firm. Thus, when the touch flexible circuit board 210 is bent to the backlight side of the flexible display panel, the risk of the edge of the second adhesive layer 600 adhered to the touch flexible circuit board 210 falling off (Peeling) can be reduced, so that the problem that the binding region T1 is bent and broken can be further prevented. In particular implementations, in embodiments of the present invention, the material of the first adhesive layer may include an oca (optical Clear adhesive) optical glue. Of course, in practical applications, other materials may be used for the first adhesive layer, and are not limited herein.
In particular implementations, in embodiments of the present invention, the material of the second adhesive layer may include OCA optical glue. Of course, in practical applications, other materials may be used for the second adhesive layer, and are not limited herein.
In particular implementations, in embodiments of the invention, the material of the base of the flexible substrate may include Polyimide (PI). Of course, in practical applications, other materials may be used for the base of the flexible substrate, and are not limited herein.
In a specific implementation, in the embodiment of the present invention, the material of the substrate of the touch substrate may also include Polyimide (PI). Of course, in practical applications, the material of the base of the touch substrate may be other materials, and is not limited herein.
In particular implementations, in embodiments of the present invention, the material of the support layer may include: polyimide (PI), ultraviolet curing glue, silicone glue, acrylic glue and/or acrylic glue. In addition, when the base of the flexible substrate, the base of the touch substrate, and the support layer are made of polyimide, the amount and type of the additive added to the polyimide solution may be adjusted so that the elastic modulus of the support layer is not less than the elastic modulus of the base of the flexible substrate and the base of the touch substrate.
In the actual process, there may be some deviation due to the limitation of the process conditions, so the embodiments of the present invention are all within the protection scope of the present invention as long as the above conditions are substantially satisfied. For example, the same reference numerals in the embodiments of the present invention may be the same within an error allowable range.
In practical applications, generally, the touch flexible circuit board 210 needs to be bent to the backlight side of the flexible display panel 100, the bending region A3 of the flexible substrate 110 needs to be bent to the backlight side of the flexible display panel 100, and in order to reserve the bending space of the bending region A3, the width of the binding region T1 needs to be set larger than the width of the step region a2 in the direction from the step region a2 to the display region a 1. Of course, the width of the binding region T1 and the width of the step region a2 may be determined by design according to the actual application environment, and are not limited herein.
In specific implementation, in the embodiment of the present invention, as shown in fig. 3, the front projection of the support layer 400 on the flexible substrate 110 covers the edge of the display area a1 and the step area a 2. In this way, the supporting layer 400 may extend in a direction from the step area a2 to the display area a1 to extend to the edge of the effective touch area T2 of the touch substrate 200, so as to improve the strength from the edge of the effective touch area T2 to the binding area T1, and further reduce the risk of wire breakage.
In practical implementation, in the embodiment of the invention, as shown in fig. 3, the orthographic projection of the support layer 400 on the touch substrate 200 also covers the binding region T1 of the touch substrate 200. This can improve the strength of the bonding area T1 of the touch substrate 200, and further reduce the risk of wire breakage.
Generally, a signal is output to the display area a1 of the Flexible substrate through at least one element of a Flexible Printed Circuit (FPC), a driver chip, and a Printed Circuit Board (PCB) to control the lighting of the display area a 1. In specific implementation, in the embodiment of the present invention, as shown in fig. 2 and fig. 3, the flexible substrate may further include a display binding region a4 located on a side of the bending region A3 facing away from the step region a 2. Further, the flexible substrate may further include a plurality of signal lines extending from the bonding region a4 to the display region a 1. Illustratively, the display binding region a4 may also include display binding terminals (PADs) electrically connected to the signal lines, respectively, to bind with at least one of the flexible circuit board, the driver chip, and the printed circuit board through the display binding terminals. Thus, a signal output from at least one of the flexible circuit board, the driver chip, and the printed circuit board can be transmitted to the display area a1 through the display bonding terminal and the signal line to drive the display area a1 to light up.
In specific implementation, in the embodiment of the present invention, as shown in fig. 3, the flexible display panel may further include: a protective layer 120 on a side of the flexible substrate 110 facing the support layer 400; wherein, the orthographic projection of the protective layer 120 on the flexible substrate 110 covers the opposite area of the binding region T1 and the step region a 2. Therefore, the traces on the stepped area a2 of the flexible substrate 110 can be protected by the protection layer 120, and the influence of the support layer 400 on the traces is reduced. Furthermore, the step area is not provided with a pixel unit for displaying, so the step area is not provided with an electroluminescent diode and a driving circuit, but with some wirings. Therefore, the step area is not generally provided with the packaging film, and the embodiment of the invention can protect the routing in the step area a2 by arranging the protective layer.
In practical implementation, in the embodiment of the present invention, as shown in fig. 3, the orthographic projection of the protection layer 120 on the flexible substrate 110 further covers the bending region a 3. The bending region is also not provided with a pixel unit for displaying, so the electroluminescent diode and the driving circuit are not provided on the bending region, but some wirings are provided. Therefore, the bending region is not generally provided with a packaging film, and the protective layer is provided in the embodiment of the present invention, so that the trace on the bending region A3 of the flexible substrate 110 can be further protected by the protective layer 120, and thus, when the bending region A3 is bent, the risk of wire breakage in the bending region A3 can be reduced.
In particular implementations, in embodiments of the present invention, the material of the protective layer may include an ultraviolet curable glue. Of course, the present invention includes, but is not limited to, this.
In the preparation process, the support layer may be prepared on the touch substrate 200, and then the touch substrate 200 and the flexible display panel 100 are attached through the first adhesive layer 300. However, the first adhesive layer 300 has a certain thickness, and the film layers on the flexible display panel 100 also have a certain thickness, and in order to take into account the tolerance of the film layers on the flexible display panel 100 and the attachment tolerance of the first adhesive layer 300, some space needs to be reserved to meet the requirement of the tolerance. In practical implementation, in the embodiment of the present invention, as shown in fig. 2 and 3, a gap may be provided between the support layer 400 and the flexible display panel 100 except for the facing area Z of the binding area T1 and the step area a 2. In practical applications, since the above tolerances required for display devices with different functions are different, the value of the gap between the support layer 400 and the flexible display panel 100 can be determined according to practical application environments, and is not limited herein.
In a specific implementation, as shown in fig. 3, the display device may further include: the first bearing layer 130 is positioned on one side of the flexible substrate 110, which is far away from the touch substrate 200; and the orthographic projection of the first carrier layer 130 on the flexible substrate 110 covers the display area a1 and the step area a 2. Since the base of the flexible substrate 110 is soft, the display area a1 and the stepped area a2 of the flexible substrate 110 are supported by providing the first carrier layer 130 to flatten the display area a1 and the stepped area a2, thereby preventing the flexible substrate 110 from curling. In addition, since the orthographic projection of the first carrier layer 130 on the flexible substrate 110 covers the display area a1 and the step area a2, the first carrier layer 130 can also cover at least a part of the support layer 400, so that the first carrier layer 130 can bear stress when the support layer 400 is bent, and the support layer 400 can be prevented from falling off (Peeling) from the touch substrate 200. And, since the second adhesive layer 600 also covers at least a portion of the bonding region T1, when the touch flexible circuit board 210 is bent, the second adhesive layer 600 can bear bending stress, and the first carrier layer 130 assists the supporting layer 400 to bear bending stress. Therefore, under the condition that the total bending stress is not changed, the stress is dispersed, so that the stress born by each part is greatly reduced, and the problems of bending, breaking and falling off can be further avoided.
In a specific implementation, as shown in fig. 3, the display device may further include: and a polarizer 140 between the touch substrate 200 and the second adhesive layer 600. The polarizing plate 140 covers the display area a1 in the orthographic projection of the flexible substrate 110. Illustratively, the polarizing plate 140 overlaps the display area a1 in a front projection of the flexible substrate 110.
In practical applications, the flexible circuit board, the driver chip, and the printed circuit board are generally located on the backlight side of the flexible substrate 110, and the bending region A3 and the display binding region a4 of the flexible substrate 110 may be bent to the backlight side of the flexible display panel 100 through a bending process, so that the display binding region a4 may be bound to at least one component of the flexible circuit board, the driver chip, and the printed circuit board.
In practical applications, the touch flexible circuit board 210 also needs to be bent to the backlight side of the flexible display panel 100 through a bending process, so that the touch flexible circuit board 210 is bound with at least one of the driving chip and the printed circuit board.
In a specific implementation, as shown in fig. 3, the display device may further include: a space filling layer 150 located on a side of the first carrier layer 130 facing away from the flexible substrate 110, and an interlayer adhesive layer 160 located between the space filling layer 150 and the first carrier layer 130. The space filling layer 150 and the first carrier layer 130 may be bonded by the interlayer adhesive layer 160, and the bending space of the bending region a3 of the flexible substrate 110 and the bending space of the touch flexible circuit board 210 may be defined by the space filling layer 150.
In particular implementations, the material of the space filling layer 150 may include foam. Of course, embodiments of the present invention include, but are not limited to, such.
In particular implementations, the interlayer adhesive layer 160 may include a composite tape. Of course, embodiments of the present invention include, but are not limited to, such.
In a specific implementation, as shown in fig. 3, the display device may further include: and the third bearing layer 170 is positioned on the side of the space filling layer 150 facing away from the flexible substrate 110. Since the base of the flexible substrate 110 is soft, by providing the first carrier layer 130, a partial region of the bending region a3 bent to the backlight side of the flexible substrate 110 is supported to be flat, thereby preventing the partial region from being curled.
In specific implementation, the display device provided in the embodiment of the present invention may be: any product or component with a display function, such as a mobile phone, a tablet computer, a television, a display, a notebook computer, a digital photo frame, a navigator and the like. Other essential components of the display device are understood by those skilled in the art, and are not described herein or should not be construed as limiting the invention.

Only the differences between the present embodiment and the above embodiments will be described below, and the descriptions of the same parts will be omitted.
In specific implementation, in the embodiment of the present invention, as shown in fig. 4, the display device may further include: the protective cover plate 500 is positioned on one side, away from the flexible substrate 110, of the touch substrate 200, the third adhesive layer 700 is positioned between the protective cover plate 500 and the touch substrate 200, and the second bearing layer 180 is positioned on one side, away from the touch substrate 200, of the flexible substrate 110; the orthographic projection of the third adhesive layer 700 on the touch substrate 200 does not overlap the binding area T1 of the touch substrate 200, and the orthographic projection of the second carrier layer 180 on the flexible substrate 110 covers the display area a1 and the step area a 2. This may prevent the flexible substrate 110 from being curled by providing the second carrier layer 180 and supporting the display area a1 and the stepped area a2 of the flexible substrate 110 to flatten the display area a1 and the stepped area a 2. The protective cover 500 is attached to the touch substrate 200 by the third adhesive layer 700. And the polarizer 140 is located between the touch substrate 200 and the third adhesive layer 700. Further, since the orthographic projection of the second carrier layer 180 on the flexible substrate 110 covers the display area a1 and the step area a2, the second carrier layer 180 can also cover at least a part of the support layer 400, so that the stress generated when the support layer 400 is bent can be carried by the second carrier layer 180, and the support layer 400 can be prevented from falling off (Peeling) from the touch substrate 200. Moreover, when the touch flexible circuit board 210 is bent, the second carrier layer 180 assists the support layer 400 to bear bending stress. Therefore, under the condition that the total bending stress is not changed, the stress is dispersed, so that the stress born by each part is greatly reduced, and the problems of bending, breaking and falling off can be further avoided.
Due to the arrangement of the second carrier layer 180, the orthographic projection of the third adhesive layer 700 on the touch substrate 200 does not overlap with the bonding area T1 of the touch substrate 200, so that the influence of the pressing force on the bonding area T1 when the third adhesive layer 700 is attached can be directly avoided, and the design of the third adhesive layer 700 can be simpler.
In particular implementations, in embodiments of the present invention, the material of the third adhesive layer may include OCA optical glue. Of course, in practical applications, other materials may be used for the third adhesive layer, and are not limited herein.

This may further increase the strength of the stepped region a2, and reduce the risk of breaking the wire in the stepped region a2 when the bend is made in the bend region A3. Since the support layer is prepared on the flexible substrate, the thickness of the support layer may be designed according to the thickness of the first adhesive layer, so that the support layer fills the gap, further improving the strength of the bonding region T1.
