All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Example 1
Referring to fig. 1, a foldable display panel according to an embodiment of the present application is disclosed. The foldable display panel includes a light emitting unit 10, a foldable electromagnetic antenna board 20, and a foldable support unit 30.
The light emitting unit 10 is an OLED (Organic Light Emitting Display, organic light emitting diode display device) display device, and the light emitting unit 10 may include a flexible substrate, a PI layer, an insulating layer, a TFT circuit layer, a metal wiring SD layer, a flat layer, an anode layer, a light emitting material layer, a packaging layer, a touch functional film layer for integrated touch, and an anti-reflection structure layer including an integrated color film.
Referring to fig. 1, in a specific application, a polarizer 101 and a cover layer 102 may be sequentially attached to the light emitting unit 10. The polarizer 101 is a combination of a substrate and a chromosome or iodine solution stretched film, and is connected to the light emitting unit 10 using a glue. The cover plate layer 102 may be made of a polymer material, such as PET or transparent PI or glass cover plate, or may be a combination cover plate, i.e. a combination of multiple layers of films.
Referring to fig. 1, the foldable electromagnetic antenna board 20 is disposed at one side of the light emitting unit 10, and the foldable electromagnetic antenna board 20 is disposed away from the light emitting surface of the light emitting unit 10. Specifically, the foldable electromagnetic antenna board 20 has an unfolded state and a folded state, and the foldable electromagnetic antenna board 20 is in the unfolded state before the foldable display panel is folded; after the foldable display panel is folded, the foldable electromagnetic antenna board 20 is in a folded state.
Referring to fig. 2, in order to provide the foldable electromagnetic antenna board 20 with the ability to be folded, an antenna is prepared by patterning a metal on a foldable flexible substrate 201 in this embodiment. Specifically, the foldable electromagnetic antenna board 20 includes a flexible substrate 201 and a metal antenna 202.
Referring to fig. 2, a display area 2011 is formed on the flexible substrate 201, the area of the flexible substrate 201 is larger than that of the display area 2011, and the edge of the flexible substrate 201 is flared by at least 5mm relative to the edge of the display area 2011, so as to meet the good coverage of the edge; the edge of the effective area of the metal antenna 202 is spaced from the edge of the display area 2011 to meet the requirement of the single-side expansion by 1mm-5 mm.
The metal antenna 202 includes a first directional antenna 2021 and a second directional antenna 2022 uniformly arranged in the display area, and the first directional antenna 2021 and the second directional antenna 2022 are perpendicular to each other. Referring to fig. 2, the traces of the first direction antenna 2021 and the traces of the second direction antenna 2022 are shown, but the traces of the first direction antenna 2021 and the second direction antenna 2022 are only shown in the figure, and each include an input trace and an output trace, and in specific applications, the traces of the first direction antenna 2021 and the second direction antenna 2022 are not limited to two circles, and the entire display area 2011 needs to be densely distributed.
In this way, with the intersecting wiring of the first direction antenna 2021 and the second direction antenna 2022, a plurality of intersecting regions can be formed in the display region 2011 of the flexible substrate 201, which can generate different responses corresponding to the electromagnetic pen to locate and form feedback. The flexible substrate 201 is used to arrange the first directional antenna 2021 and the second directional antenna 2022, so that the electromagnetic antenna board is foldable.
Wherein the materials of the first direction antenna 2021 and the second direction antenna 2022 may be Cu/Al/Ag, and the thickness is 1 μm-8 μm, so as to satisfy the balance between the foldability and the resistance performance of the first direction antenna 2021 and the second direction antenna 2022. If desired to meet the general folding performance (R1.5100K dynamic bends), the thickness of the first direction antenna 2021 and the second direction antenna 2022 may be required to be at most 5um, preferably at most 3um; and forming by adopting a method of further etching after coating or sputtering, thereby forming a set pattern.
Referring to fig. 3 and 4, the foldable electromagnetic antenna board 20 may be perforated by the flexible substrate 201 to lead out the input trace and the output trace of the first directional antenna 2021 and the second directional antenna 2022 and to close up the display area. Wherein, the illustrated layers 203 are all organic insulating flat layers, and can be formed by immobilization of acrylic ester.
Referring to fig. 5 and 6, the foldable electromagnetic antenna board 20 may also adopt a mode of opening the organic insulation flat layer 203 to lead out the input wires and the output wires of the first directional antenna 2021 and the second directional antenna 2022 and close up the display area, so as to avoid punching the flexible substrate 201.
Referring to fig. 1, the foldable support unit 30 is disposed at a side of the light emitting unit 10 away from the light emitting surface, and the foldable support unit 30 is connected to the foldable electromagnetic antenna board 20, thereby supporting the foldable electromagnetic antenna board 20 and the light emitting unit 10. The foldable support unit 30 also has an unfolded state and a folded state, and the foldable support unit 30 is in the unfolded state before the foldable display panel is folded; after the foldable display panel is folded, the foldable support unit 30 is in a folded state.
Referring to fig. 7, the foldable support unit 30 includes a support portion 301, and the support portion 301 has a bending region 3011 thereon, and the support portion 301 is switchable from an unfolded state to a bent state by the bending region 3011. The support 301 is connected to the foldable electromagnetic antenna board 20 by an adhesive.
In this way, by providing the light emitting unit 10 while providing the foldable electromagnetic antenna board 20 and the foldable support unit 30 on the side of the light emitting unit 10 facing away from the light emitting surface, the foldable electromagnetic antenna board 20 is connected to the foldable support unit 30; the foldable electromagnetic antenna board 20 is utilized to realize compatibility between the foldable display panel and the electromagnetic screen, namely, under the condition that the display panel is foldable, the condition that the display panel can be touched by an electromagnetic pen is also met.
In one embodiment, referring to fig. 7, the supporting portion 301 is disposed on a side of the foldable electromagnetic antenna board 20 away from the light emitting unit 10, and the material of the supporting portion 301 is metal (e.g., steel, aluminum, titanium alloy), carbon fiber resin composite material, or reinforced plastic (e.g., nylon or aramid). When the supporting portion 301 is made of metal, electromagnetic interference may be generated to the foldable electromagnetic antenna, so that the supporting portion 301 is preferably made of a non-conductive material such as carbon fiber resin composite material or reinforced plastic, for example, carbon fiber reinforced polyether ether ketone or carbon fiber reinforced polyimide. When the supporting portion 301 is made of a metal material, the thickness of the supporting portion 301 is 60 μm to 100 μm; when the support portion 301 is made of a carbon fiber resin composite material or reinforced plastic, the thickness of the support portion 301 is 100 μm to 300 μm.
In a specific application, since the supporting portion 301 needs to be assembled and connected with the whole machine, a conductive coating layer is further required to be disposed on a side of the supporting portion 301 away from the light emitting surface of the light emitting unit, and a resistance value of the conductive coating layer is less than 0.5 ohm.
In one embodiment, referring to fig. 8, the supporting portion 301 may be disposed between the light emitting unit 10 and the foldable electromagnetic antenna board 20, in which case, the supporting portion 301 is made of a reinforced plastic with low conductivity, and the sheet resistance of the supporting portion 301 is greater than 10 7 Ohm, in this way, can also play a role in strengthening the foldable electromagnetic antenna board 20 in case of meeting a certain conductivity.
In a specific application, when the supporting portion 301 is made of a metal material or a carbon fiber resin composite material, holes are required to be formed in the bending region 3011 of the supporting portion 301 to meet the bending requirement, and the hole patterns are shown in fig. 13 and 14; when the supporting portion 301 is made of reinforced plastic, no hole is needed to be formed, so that the bending requirement can be met.
In an embodiment, referring to fig. 9, the foldable supporting unit 30 further includes a supporting film layer 302, where the supporting film layer 302 is disposed between the light emitting unit 10 and the foldable electromagnetic antenna board 20, and the supporting film layer may be made of a polymer material, such as polyimide substrate or parylene, and the supporting film layer 302 is perforated at a position corresponding to the bending region 3011, so as to improve bending performance of the supporting film layer 302 and avoid breakage of the supporting film layer 302. The supporting film layer 302 may be connected to the light emitting unit 10 and the foldable electromagnetic antenna board 20 through a glue material.
In particular applications, to further reduce the thickness of the foldable display panel, the foldable electromagnetic antenna board 20 may be directly used instead of the supporting film layer 302, thereby eliminating the thickness requirement of the supporting film layer 302.
In one embodiment, referring to fig. 10, the foldable display panel further includes a magnetic conductive layer 40, where the magnetic conductive layer 40 is disposed on a side of the foldable electromagnetic antenna board 20 away from the light emitting unit 10, the magnetic conductive layer 40 may be made of an iron-based nanocrystalline material, an amorphous material, or ferrite, and has a thickness of 30 μm-100 μm, and the magnetic conductive layer 40 has a relative magnetic permeability of at least 100 and a relative magnetic loss of at most 100. The magnetically permeable layer 40 is bonded to the foldable electromagnetic antenna plate 20 by an adhesive.
The arrangement of the magnetically conductive layer 40 can improve the electromagnetic utilization rate of the foldable electromagnetic antenna board 20, avoid the interference of metal to electromagnetic, and improve the inductance response strength of the electromagnetic pen, so that the electromagnetic pen can perform touch control better, therefore, when the magnetically conductive layer 40 is added, the material of the supporting portion 301 can be selected to use a metal material.
