Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. 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 fall within the scope of the application.
In order to solve the problem that the metal layer in the overlap region is prone to overlap failure due to the size limitation of the overlap region when the flexible display panel is bent, embodiments of the present application provide a flexible display panel and a display device, which will be described below with reference to the accompanying drawings.
For example, referring to fig. 1, fig. 1 is a schematic structural diagram of a display device according to an embodiment of the application. The embodiment of the application provides a display device 1, and the display device 1 may include a flexible display panel 10 and a driving chip 20. The driving chip 20 is electrically connected to the flexible display panel 10, and the driving chip 20 is used for driving the display or bending action of the flexible display panel 10, which is also understood as that the driving chip 20 is a control center of the display device 1. The display device 1 may be bent, folded or otherwise deformed to exhibit different display effects, thereby satisfying the viewing habits of different users on the display device 1. The display device 1 may be a mobile electronic device such as a mobile phone or a tablet, or the display device 1 may be a device having a display function such as a computer device, a television, or a car-mounted computer.
The display device 1 may include an OLED (Organic Light-Emitting Diode) device, or the Light-Emitting form of the components in the display device 1 is an OLED Light-Emitting form, where an OLED is a current-type Organic Light-Emitting device that emits Light by injection and recombination of carriers, and the Light-Emitting intensity is proportional to the injected current. Under the action of an electric field, holes generated by the anode and electrons generated by the cathode of the OLED move, are respectively injected into the hole transport layer and the electron transport layer, and migrate to the light emitting layer. When the two meet at the light emitting layer, an energy exciton is generated, thereby exciting the light emitting molecule to finally generate visible light. The organic plastic layer of an OLED is thinner, lighter, and more flexible than the crystalline layer of an LED (Light-Emitting Diode) or LCD (Liquid Crystal Display). In addition, the OLED can be produced on different flexible substrate materials such as plastics and resins, and an organic layer is evaporated or coated on a plastic substrate, so that a soft screen or a flexible screen can be realized. OLED has the advantages of self-luminescence, low driving voltage, high luminous efficiency, short response time, high definition and contrast, wide viewing angle, wide use temperature range and the like, and is considered to be the display with the most development potential.
Among them, the flexible display panel 10 is a main device in the display apparatus 1, and the bending or folding of the display apparatus 1 is generally performed in consideration of the bending or folding of the flexible display panel 10. In order to illustrate the flexible display panel 10 according to the embodiment of the present application to solve the problem of poor metal lap joint in the lap joint area, the following description will be given of the composition structure and the operation principle of the flexible display panel 10 with reference to the accompanying drawings.
For example, please refer to fig. 1 in combination with fig. 2, fig. 2 is a schematic structural diagram of a flexible display panel in the display device shown in fig. 1. Embodiments of the present application also provide a flexible display panel 10, the flexible display panel 10 may also be referred to as a flexible screen. From the viewpoint of the constituent layer structure of the flexible display panel 10, the flexible display panel 10 may generally include a light emitting layer and a driving layer driving the light emitting layer to emit light. The flexible display panel 10 may include a display region 11 and a non-display region 12, the non-display region 12 being disposed around the display region 11, as viewed from a display surface facing the flexible display panel 10. The non-display area 12 may include a landing zone 120. The display area 11 is an area where the flexible display panel 10 displays a screen. The non-display area 12 may include a landing area 120 and a packaging area. The overlap region 120 may be understood as a scan line or signal line exit within the display region 11. For example, the overlap region 120 may be divided into a cathode overlap region for overlapping the cathode with the VSS signal line and a bonding region. The bonding area is used to bond all signal lines of the display area 11 with the driving chip 20, the control chip, or the integrated circuit. The landing area 120 is not typically shown and therefore this area may also be used to encapsulate the flexible display panel 10. It should be noted that, in the preparation of the flexible display panel 10, the preparation of the structure in the overlap region 120 is generally performed following the preparation of the structure in the display region 11. The display region 11 may have a laminated structure, and thus, the overlap region 120 may have a laminated structure.
Among them, ACF (Anisotropic Conductive Film ) is generally used when the metal of the bonding area 120 is bonded to the driving chip 20, and the ACF is characterized by a significant difference between the electrical conduction direction of the Z axis and the resistance characteristics of the XY insulation plane. When the difference between the Z-axis on-resistance value and the XY plane insulation resistance value exceeds a certain ratio, the Z-axis on-resistance value and the XY plane insulation resistance value can be called as good conduction anisotropy. The conduction principle of ACF may be: the conductive particles are used to connect the electrodes between the IC chip and the substrate to make them conductive, and at the same time, the conductive short circuit between the adjacent two electrodes can be avoided, so as to achieve the purpose of conductive in the Z-axis direction only.
However, with the progress of science and technology, the full screen is gradually raised, which makes the size of the overlap region 120 limited, and when the flexible display panel 10 is bent, the ACF glue for bonding the metal of the overlap region 120 and the driving chip 20 is easily warped, and thus, the metal bonded in the overlap region 120 is easily subject to the problem of poor overlap, thereby affecting the display quality of the flexible display panel 10.
In order to solve the above-mentioned problem that the binding size of the metal of the overlap region 120 is limited, the embodiment of the present application improves the structure of the overlap region 120. For example, please refer to fig. 3 in combination with fig. 1 and fig. 2, fig. 3 is a schematic cross-sectional view of a first cross-section of the overlap region in the flexible display panel shown in fig. 2. A first insulating layer 121, a first metal layer 122, and an auxiliary structure 123 may be disposed in the overlap region 120. The first metal layer 122 is disposed on a side of the first insulating layer 121 facing away from the display surface of the flexible display panel 10, and exposes at least a part of a region in the display direction X of the flexible display panel 10, where the first metal layer 122 is exposed, for binding with the driving chip 20. The auxiliary structure 123 is disposed on a side of the first metal layer 122 facing away from the first insulating layer 121, and is disposed corresponding to an exposed region of the first metal layer 122, so that a portion of the exposed region of the first metal layer 122 is raised. By arranging the auxiliary structure 123 below the exposed area corresponding to the first metal layer 122, the auxiliary structure 123 can enable a part of the exposed area of the first metal layer 122 to be raised, so that the overlap area between the exposed area of the first metal layer 122 and the driving chip 20 can be increased, and further the overlap effect of the first metal layer 122 is good, so that the display quality of the flexible display panel 10 is improved.
Wherein the first insulating layer 121 and the first metal layer 122 are disposed following the layer structure within the display area 11. The first insulating layer 121 may be a passivation layer, which may also be referred to as a PVS layer, for example. The first insulating layer 121 may be an insulating layer near the display surface of the flexible display panel 10. The first metal layer 122 is disposed on a side of the first insulating layer 121 facing away from the display surface of the flexible display panel 10. The first insulating layer 121 may be provided with an opening to expose at least a portion of the first metal layer 122, the exposed portion of the first metal layer 122 for binding with the driving chip 20. For example, an opening may be disposed in a middle region of the first insulating layer 121, and the remaining portion of the first insulating layer 121 may be disposed around the opening, where at least a portion of the first metal layer 122 is disposed in the opening, for example, a portion of the first metal layer 122 is disposed corresponding to the opening, and another portion of the first metal layer 122 may be connected to the first insulating layer 121, and it may be understood that a portion of the first insulating layer 121 is connected to a portion of the first metal layer 122 to fix the first metal layer 122.
The positional relationship between the first insulating layer 121 and the first metal layer 122 is not limited to the above, and for example, the first metal layer 122 may be provided on at least one side edge of the first insulating layer 121, and accordingly, the auxiliary structure 123 may be provided directly under the exposed region of the corresponding first metal layer 122.
The auxiliary structure 123 is disposed below the exposed portion of the first metal layer 122, that is, the auxiliary structure 123 is disposed on one side of the first metal layer 122 away from the display surface of the flexible display panel 10, so that a portion of the exposed portion of the first metal layer 122 is partially protruded, so as to increase the overlapping area of the first metal layer 122, and further improve the overlapping effect.
Illustratively, the first metal layer 122 may include a first region 1221, a second region 1223, and a third region 1225 connected to each other, the first region 1221 being a connection region of the first metal layer 122 and the first insulating layer 121, the second region 1223 being located between the first region 1221 and the third region 1225, the third region 1225 being a protrusion region. It is understood that the second and third areas 1223 and 1225 may be exposed areas of the first metal layer 122 facing a side of the display surface of the flexible display panel 10.
It should be noted that, the second area 1223 may be disposed around the third area 1225, and accordingly, the first area 1221 may be disposed around the second area 1223. It is understood that the second region 1223 and the first region 1221 may each be annular structures.
The shape of the auxiliary structure 123 may take various forms, please refer to fig. 1 to 3 in combination with fig. 4 to 7, fig. 4 is a schematic view of a first metal layer and a first structure of the auxiliary structure in the overlap region shown in fig. 3, fig. 5 is a schematic view of a second structure of the first metal layer and the auxiliary structure in the overlap region shown in fig. 3, fig. 6 is a schematic view of a third structure of the first metal layer and the auxiliary structure in the overlap region shown in fig. 3, and fig. 7 is a schematic view of a fourth structure of the first metal layer and the auxiliary structure in the overlap region shown in fig. 3.
For example, the auxiliary structure 123 may include a first sub-portion 1231, the first sub-portion 1231 is disposed corresponding to the third region 1225, and a side surface of the first sub-portion 1231 facing the first metal layer 122 is parallel to the third region 1225. It should be noted that, the first sub-portion 1231 may have a linear structure, and the width thereof may be set as required, and the area of the first sub-portion 1231 does not exceed the area of the third region 1225.
Wherein the height of the third area 1225 is greater than the height of the second area 1223 in the display direction X of the flexible display panel 10. That is, the third area 1225 protrudes from the second area 1223, and the installation area of the third area 1225 protruding from the second area 1223 is larger than the installation mode of the third area 1225 and the second area 1223 on the same plane, so as to increase the binding area of the first metal layer 122 and the driving chip 20.
In an exemplary embodiment, the auxiliary structure 123 may further include at least one second sub-portion 1233, each of the second sub-portions 1233 is disposed corresponding to the third region 1225, and each of the second sub-portions 1233 is disposed obliquely to the first sub-portion 1231. It is understood that when there are a plurality of second sub-portions 1233, the plurality of second sub-portions 1233 may be disposed in parallel, and the second sub-portions 1233 may be disposed at an angle with respect to the first sub-portion 1231. For example, each of the second sub-portions 1233 may be perpendicular to the first sub-portion 1231.
The at least one second sub-part 1233 may be connected to the first sub-part 1231, and the at least one second sub-part 1233 may be disconnected from the first sub-part 1231. The protruding conditions of the first metal layer 122 corresponding to the above conditions are different, but the first metal layer 122 may be in a state of being in a high-low fluctuation, that is, the first metal layer 122 may be in a protruding form or be in a protruding area in an array form. The auxiliary structure 123 thus provided is more effective in increasing the overlap area of the first metal layer 122. When there are a plurality of the second sub-parts 1233, at least one of the second sub-parts 1233 is connected with the first sub-part 1231.
In this example, all the second sub-portions 1233 are connected with the first sub-portion 1231, and all the second sub-portions 1233 are disposed perpendicular to the first sub-portion 1231. In the first case, each of the second sub-portions 1233 is disposed in parallel and at an interval, one end of each of the second sub-portions 1233 is connected to the first sub-portion 1231, and the other end of each of the second sub-portions 1233 is a free end. In the second case, each of the second sub-portions 1233 is disposed in parallel and spaced apart from each other, and the first sub-portion 1231 connects all of the second sub-portions 1233 from the middle position of each of the second sub-portions 1233.
Of course, other forms of constituent shapes are possible for the shape of the auxiliary structure 123, which are not illustrated here.
For the placement position of the auxiliary structure 123, the auxiliary structure 123 may be adjacent to the first metal layer 122, and the auxiliary structure 123 may be spaced apart from the first metal layer 122.
For example, please refer to fig. 1-7 in combination with fig. 8, fig. 8 is a schematic diagram of a second cross-sectional structure of the overlap region in the flexible display panel shown in fig. 2. The flexible display panel 10 may further include a second insulating layer 124, where the second insulating layer 124 is disposed on a side of the first metal layer 122 facing away from the display surface of the flexible display panel 10 and is connected to the first insulating layer 121. It will be appreciated that in the preparation of the flexible display panel 10, the second insulating layer 124 is disposed first, then the first metal layer 122 is disposed on the second insulating layer 124, and finally the first insulating layer 121 is disposed on the second insulating layer 124 and covers a portion of the first metal layer 122, that is, the first region 1221 of the first metal layer 122.
The second insulating layer 124 may be a combination layer of an ILD layer (Inter-Level Dielectric) and a Buffer layer (Buffer layer), which is formed following the preparation of the layer structure in the display area 11. An auxiliary structure 123 may be disposed between the second insulating layer 124 and the first metal layer 122, i.e., the auxiliary structure 123 is in direct contact with the first metal layer 122. Of course, an auxiliary structure 123 may be disposed on a side of the second insulating layer 124 facing away from the first metal layer 122, i.e. the auxiliary structure 123 is spaced apart from the first metal layer 122, so that when the shape of the auxiliary structure 123 is disposed, the second insulating layer 124 may take on a certain fault tolerance responsibility, i.e. the auxiliary structure 123 protrudes a certain shape, and then the second insulating layer 124 modifies the protruding shape of the auxiliary structure 123 and then lifts up the first metal layer 122, so as to prevent the first metal layer 122 from cracking when the first metal layer 122 is thinner. In some embodiments, the auxiliary structure 123 may be disposed on both sides of the second insulating layer 124, i.e., the auxiliary structure 123 is disposed between the second insulating layer 124 and the first metal layer 122, while the auxiliary structure 123 is disposed on a side of the second insulating layer 124 facing away from the first metal layer 122. The two auxiliary structures 123 may be configured to match each other, so that the protruding area of the first metal layer 122 is not uniform, and the binding or overlapping area of the first metal layer 122 is increased.
Wherein the material for the auxiliary structure 123 may be selected as desired. For example, the auxiliary structure 123 may be a non-metal material, for example, the material of the auxiliary structure 123 may be the same as that of the second insulating layer 124. The material of the second insulating layer 124 may be a SiO material.
The material of the auxiliary structure 123 may also be a metal material, for example. For example, the auxiliary structure 123 may be disposed at a side of the second insulating layer 124 facing away from the first metal layer 122. The landing zone 120 may further include a third insulating layer 125, which third insulating layer 125 may also be referred to as PI layer (polyimide layer), and the third insulating layer 125 is disposed on a side of the auxiliary structure 123 facing away from the first metal layer 122, and thus, the third insulating layer 125 may also be understood as a base layer of the landing zone 120. The auxiliary structure 123 may be understood as a first metal layer laid when the layer structure of the display area 11 is disposed, and the auxiliary structure 123 is etched to a desired shape to increase the overlapping area of the first metal layer 122.
Wherein, the auxiliary structure 123 may be electrically connected with the first metal layer 122, so that the area of the first metal layer 122 may be increased, thereby reducing the resistance of the first metal layer 122. For example, please refer to fig. 1 to 8 in combination with fig. 9 and 10, fig. 9 is a schematic structural view of a portion of the overlap region in the flexible display panel shown in fig. 2, and fig. 10 is a schematic structural view of another angle of the overlap region shown in fig. 9.
