Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.
Example one
Referring to fig. 1, a foldable display panel disclosed in the embodiments of the present application is shown. The foldable display panel includes a light emitting unit 10, a foldable electromagnetic antenna panel 20, and a foldable support unit 30.
The Light Emitting unit 10 is an OLED (Organic Light Emitting diode Display) 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 routing SD layer, a planarization layer, an anode layer, a Light Emitting material layer, a packaging layer, a touch functional film layer with integrated touch, and an anti-reflection structure layer with an integrated color film.
Referring to fig. 1, in a specific application, a polarizer 101 and a cover plate layer 102 may be sequentially attached to the light emitting unit 10. The polarizer 101 is a combination of a base material and a stretched film of a chromosome or iodine solution, and is connected to the light emitting unit 10 by a glue material. The cover layer 102 may be made of a polymer material, such as PET or a transparent PI or glass cover, or a combination cover, i.e., a combination of multiple layers.
Referring to fig. 1, a foldable electromagnetic antenna panel 20 is disposed at one side of a light emitting unit 10, and the foldable electromagnetic antenna panel 20 is disposed away from a light emitting surface of the light emitting unit 10. Specifically, the foldable electromagnetic antenna plate 20 has an unfolded state and a folded state, and before the foldable display panel is folded, the foldable electromagnetic antenna plate 20 is in the unfolded state; after the foldable display panel is folded, the foldable electromagnetic antenna panel 20 is in a folded state.
Referring to fig. 2, in order to make the foldable electromagnetic antenna panel 20 foldable, in this embodiment, the antenna is prepared by patterning metal on the foldable flexible substrate 201. Specifically, the foldable electromagnetic antenna panel 20 includes a flexible substrate 201 and a metal antenna 202.
Referring to fig. 2, the flexible substrate 201 has a display area 2011, an area of the flexible substrate 201 is larger than an area of the display area 2011, and an edge of the flexible substrate 201 extends outward by at least 5mm relative to an edge of the display area 2011, so as to satisfy good coverage of the edge; the distance between the edge of the active area of the metal antenna 202 and the edge of the display area 2011 needs to be synchronously a distance which satisfies the unilateral outward expansion of 1mm to 5 mm.
The metal antenna 202 includes a first directional antenna 2021 and a second directional antenna 2022 which are 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 trace of the first directional antenna 2021 and the trace of the second directional antenna 2022 are shown, but only two loops of the trace of the first directional antenna 2021 and the second directional antenna 2022 are shown in the drawing, and both include an input trace and an output trace, and in a specific application, the trace of the first directional antenna 2021 and the second directional antenna 2022 is not limited to two loops, and the whole display area 2011 needs to be densely distributed.
In this way, by using the first directional antenna 2021 and the second directional antenna 2022 to cross the wiring, a plurality of cross areas can be formed in the display area 2011 of the flexible substrate 201, and the cross areas can be positioned and form feedback by generating different responses corresponding to the electromagnetic pen. The flexible substrate 201 is used to arrange the first directional antenna 2021 and the second directional antenna 2022, which satisfies the requirement of folding the electromagnetic antenna board.
The first direction antenna 2021 and the second direction antenna 2022 may be made of Cu/Al/Ag with a thickness of 1 μm to 8 μm, so as to satisfy the balance between the folding property and the resistance property of the first direction antenna 2021 and the second direction antenna 2022. If it is necessary to satisfy general folding performance (R1.5100K dynamic bending), it may be required that the thickness of the first direction antenna 2021 and the second direction antenna 2022 is at most 5um, preferably at most 3 um; and forming by adopting a method of further etching after film 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 extract the input traces and the output traces of the first directional antenna 2021 and the second directional antenna 2022 and to densely arrange the display area. The illustrated 203 is an organic insulating planarization layer, which may be formed by fixing acrylate.
Referring to fig. 5 and 6, the foldable electromagnetic antenna panel 20 may also use a hole-opened organic insulating flat layer 203 to lead out the input traces and the output traces of the first directional antenna 2021 and the second directional antenna 2022 and to densely arrange the display area, thereby avoiding punching the flexible substrate 201.
Referring to fig. 1, a foldable support unit 30 is disposed at a side of the light emitting unit 10 away from the light exit surface, and the foldable support unit 30 is connected to the foldable electromagnetic antenna panel 20, so as to support the foldable electromagnetic antenna panel 20 and the light emitting unit 10. The foldable support unit 30 also has an unfolded state and a folded state, and before the foldable display panel is folded, the foldable support unit 30 is in the unfolded state; after the foldable display panel is folded, the foldable supporting unit 30 is in a folded state.
Referring to fig. 7, the foldable support unit 30 includes a support portion 301, the support portion 301 has a bending region 3011, and the support portion 301 can be switched from an unfolded state to a bent state through the bending region 3011. The support portion 301 is connected to the foldable electromagnetic antenna panel 20 by an adhesive.
In this way, by arranging the light emitting unit 10 and arranging the foldable electromagnetic antenna panel 20 and the foldable supporting unit 30 on the side of the light emitting unit 10 away from the light emitting surface, the foldable electromagnetic antenna panel 20 is connected with the foldable supporting unit 30; the foldable electromagnetic antenna plate 20 is utilized to realize compatibility between the foldable display panel and the electromagnetic screen, that is, 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, a supporting portion 301 is disposed on a side of the foldable electromagnetic antenna panel 20 away from the light emitting unit 10, and a material of the supporting portion 301 is a metal (e.g., steel, aluminum, titanium alloy), a carbon fiber resin composite material, or a reinforced plastic (e.g., nylon or aramid). When the supporting portion 301 is made of metal, electromagnetic interference may be generated on the foldable electromagnetic antenna, and therefore 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 polyetheretherketone or carbon fiber reinforced polyimide. When the supporting part 301 is made of metal material, the thickness of the supporting part 301 is 60 μm-100 μm; when the support portion 301 is made of carbon fiber resin composite material or reinforced plastic, the thickness of the support portion 301 is 100 μm to 300 μm.
In specific application, since the supporting portion 301 needs to be assembled and connected with the whole machine, a conductive plating layer needs 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 plating layer is less than 0.5 ohm.
In one embodiment, referring to fig. 8, the supporting portion 301 may also 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 reinforced plastic with low conductivity, and the sheet resistance of the supporting portion 301 is greater than 107Ohm, which may also serve to strengthen the foldable electromagnetic antenna panel 20 while satisfying certain conductive capabilities.
In a specific application, when the supporting portion 301 is made of a metal material or a carbon fiber resin composite material, holes need 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, the bending requirement can be satisfied without forming a hole.
In an embodiment, referring to fig. 9, the foldable supporting unit 30 further includes a supporting film 302, the supporting film 302 is disposed between the light emitting unit 10 and the foldable electromagnetic antenna panel 20, the supporting film may be made of a polymer material, such as a polyimide substrate or parylene ester, and holes are formed in positions of the supporting film 302 corresponding to the bending regions 3011, so as to improve bending performance of the supporting film 302 and prevent the supporting film 302 from breaking. The support film layer 302 may be connected with the light emitting unit 10 and the foldable electromagnetic antenna panel 20 through a glue material.
In a specific application, in order to further reduce the thickness of the foldable display panel, the foldable electromagnetic antenna panel 20 may be directly used to replace the supporting film layer 302, thereby eliminating the requirement of the thickness of the supporting film layer 302.
In an embodiment, referring to fig. 10, the foldable display panel further includes a magnetic conduction layer 40, the magnetic conduction layer 40 is disposed on a side of the foldable electromagnetic antenna board 20 away from the light emitting unit 10, the magnetic conduction layer 40 may be made of an iron-based nanocrystalline material, an amorphous material, or a ferrite, and has a thickness of 30 μm to 100 μm, a relative magnetic permeability of at least 100 of the magnetic conduction layer 40, and a relative magnetic loss of at most 100. The magnetic conductive layer 40 and the foldable electromagnetic antenna plate 20 are connected by an adhesive.
The arrangement of the magnetic conduction layer 40 can improve the electromagnetic utilization rate of the foldable electromagnetic antenna board 20, avoid the interference of metal to electromagnetism, and improve the inductance response strength of the electromagnetic pen, so that the electromagnetic pen can better perform touch control, and therefore, when the magnetic conduction layer 40 is added, the material of the support portion 301 can be selected to use a metal material.
