DETAILED DESCRIPTION
[0013] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the specific embodiments of this application and the corresponding drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0014] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a particular order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "first," "second," and the like generally distinguish objects of a class and do not limit the number of objects. For example, the first object may be one or more.
[0015] The technical solutions disclosed in various embodiments of the present application are described in detail below with reference to the accompanying drawings.
[0016] Referring to Figures 1 to 3, an embodiment of the present application discloses an electronic device. The disclosed electronic device may include a housing, a display screen 100, and an electrical connection portion 110. The electronic device may be a mobile phone, a tablet computer, a wearable device, a vehicle-mounted device, a laptop computer, etc. The housing is provided with a mounting position for the display screen 100. The display screen 100 may be assembled with the housing by bonding, snapping, etc., and together with the housing, form an inner cavity of the device. The display screen 100 may be a liquid crystal display (LCD), a light emitting diode (LED) display, an organic light emitting diode (OLED) display, etc.
[0017] The first electrical component 200 and the second electrical component 300 are disposed within the inner cavity of the device. The first electrical component 200 and the second electrical component 300 may be components such as the main board, sub-board, or sensor of the electronic device. The first electrical component 200 and the second electrical component 300 may be electrically connected via the electrical connection portion 110. For example, the first electrical component 200 is the main board of the electronic device, and the second electrical component 300 is the sub-board of the electronic device. The main board is primarily responsible for most of the system functional operations of the electronic device, while the sub-board is primarily responsible for functions such as charging and audio signal transmission. The main board and the sub-board are located at different locations within the inner cavity of the device, and the main board and the sub-board may be electrically connected or connected in other forms via the electrical connection portion 110.
[0018] The electrical connection portion 110 is provided on the display screen 100. Specifically, it can be provided on the end surface of the display side or non-display side of the display screen 100, or it can be embedded in the interior of the display screen 100. This embodiment of the present application is not limited to this. The electrical connection portion 110 can be made of a conductive material. For example, the electrical connection portion 110 can be made of silver, copper, indium tin oxide (ITO), graphene, etc.
[0019] As can be seen from the above, the electronic device disclosed in the embodiment of the present application improves the relevant technology. By integrating the electrical connection part 110 into the display screen 100, the first electrical device 200 and the second electrical device 300 in the device cavity of the electronic device can be electrically connected through the electrical connection part 110. There is no need to lay out the flexible circuit board 400 over a large area in the device cavity, which greatly saves the space in the device cavity and is conducive to the lightweight and thinning of the electronic device.
[0020] In an optional embodiment of the present application, the display screen 100 includes a plurality of laminates stacked in sequence, and different laminates have different functions. Adjacent laminates can be bonded together by optical adhesive or encapsulated and fixed by an encapsulation layer 150. The electrical connection portion 110 is provided between any two adjacent laminates or within any laminate. It should be noted that the laminate structure of the display screen 100 requires lamination. Before the laminate is laminated, the electrical connection portion 110 can be provided between adjacent laminates, and then the lamination process can be performed. Alternatively, the electrical connection portion 110 can be pre-set within any laminate. For example, a groove, through hole or other structure can be provided within the laminate to accommodate the electrical connection portion 110. The electrical connection portion 110 can be laid between any two adjacent laminates or within any laminate by electroplating, physical vapor deposition, chemical vapor deposition or the like.
[0021] Exemplarily, the multiple layers of the display screen 100 include a cover layer and a display layer. The electrical connection part 110 can be set between the cover layer and the display layer, and optical glue can be filled in other areas between the cover layer and the display layer. Alternatively, a groove can be set on the cover layer, and the electrical connection part 110 can be laid in the groove, which will not affect the thickness of the display screen 100 layers.
[0022] In an optional embodiment of the present application, one of the multiple layers of the display screen 100 includes a display layer, and the electrical connection portion 110 is located on the light-emitting side of the display layer. For example, the layers located on the light-emitting side may include a polyester resin (Polyethylene terephthalate, PET) cover layer, an optically clear adhesive (OCA) layer, a light-transmitting glass layer, a polarizer layer, etc. The electrical connection portion 110 may be disposed between the aforementioned layers or within any of the layers. Since the electrical connection portion 110 is located on the light-emitting side of the display layer, to avoid affecting the display effect, the electrical connection portion 110 may be a light-transmitting optical connection portion, which not only performs a conductive function but also has a certain degree of light transmittance.
[0023] In another optional solution of the present application, one of the multiple stacked layers of the display screen 100 includes a display layer, and the electrical connection portion 110 is located on the backlight side of the display layer. Exemplarily, the stacked layer located on the backlight side may include an insulating layer, an encapsulation layer 150, a steel sheet layer, etc. The electrical connection portion 110 may be provided between the above stacked layers or within any stacked layer. Since the electrical connection portion 110 is located on the backlight side of the display layer, there is no need to consider the impact of the electrical connection portion 110 on the display effect. The electrical connection portion 110 may be a non-phototransparent photoelectric connection portion made of a conductive material such as silver, copper, or graphene, and the cost is relatively low. Of course, the electrical connection portion 110 located on the backlight side of the display screen 100 may also be a phototransparent photoelectric connection portion, and this embodiment of the present application is not limited to this.
[0024] In an optional solution, the electrical connection portion 110 is an ITO layer. ITO has excellent electrical conductivity and light transmittance. The ITO layer can be disposed between any two adjacent stacked layers or within any stacked layer. The ITO layer can include multiple parallel ITO lines, with adjacent ITO lines spaced apart to avoid mutual interference. The ITO lines can be deposited by physical vapor deposition, evaporation, or other methods. By adjusting the proportion of metal components during the process, the line width and thickness of the ITO lines can be adjusted, thereby improving the current flow capacity of the circuit and reducing heat generation.
[0025] In an optional embodiment of the present application, the display screen 100 includes a light-transmitting protective layer 120, an adhesive layer 130, a polarizer layer 140, an encapsulation layer 150, a first insulating layer 160, a base layer 170, a second insulating layer 180, and a support layer 190 stacked in sequence. The light-transmitting protective layer 120 can be made of a wear-resistant and scratch-resistant material such as PET or polymer resin (PolyResin, PR), and is mainly used to protect the internal stacking. The adhesive layer 130 is arranged between the light-transmitting protective layer 120 and the polarizer layer 140. The adhesive layer 130 can be an optically clear adhesive (OCA) layer, a photosensitive adhesive (Ultraviolet Rays, UV) layer, etc. The encapsulation layer 150 is used to encapsulate the base layer 170 and the display layer (not shown in the drawings) located on the base layer 170. The encapsulation layer 150 is made of a transparent material, such as glass or plastic, and is mainly used to protect the display layer from being affected by oxidation or moisture. The first insulating layer 160 and the second insulating layer 180 are respectively located on both sides of the base layer 170 along its own thickness direction, and play a role of insulation protection. The supporting layer 190 is arranged on the side of the second insulating layer 180 away from the base layer 170. The supporting layer 190 is made of materials such as steel sheets and plays a supporting and protective role for the display screen 100.
[0026] The electrical connection portion 110 is disposed between the first insulating layer 160 and the base layer 170. The electrical connection portion 110 can be applied to the surface of the first insulating layer 160 or the base layer 170 by physical vapor deposition, sputtering deposition, or the like, and then the first insulating layer 160 and the base layer 170 are laminated together. Alternatively, the electrical connection portion 110 can be integrated within the base layer 170, and space can be reserved for the electrical connection portion 110 by slotting the base layer 170, thereby reducing the thickness of the laminate.
[0027] In an optional embodiment of the present application, the electronic device further includes a flexible circuit board 400, and both ends of the electrical connection portion 110 have a joint portion 111 exposed to the display screen 100. Accordingly, the number of flexible circuit boards 400 can be two, and the joint portion 111 can be located in the non-display area at the edge of the display screen 100 to avoid affecting the display image. The first electrical device 200 or the second electrical device 300 can be electrically connected to the joint portion 111 through the flexible circuit board 400, and the flexible circuit board 400 and the electrical connection portion 110 can be electrically connected through a binding process. By providing the flexible circuit board 400, on the one hand, the reliability of the connection between the electrical connection portion 110 and the first electrical device 200 or the second electrical device 300 is improved, and on the other hand, it can prevent the first electrical device 200 or the second electrical device 300 from directly pulling the electrical connection portion 110, thereby reducing the risk of damage to the electrical connection portion 110.
[0028] In a further solution, in order to improve the convenience of connecting the flexible circuit board 400 with the first electrical device 200 or the second electrical device 300, a plug connector 410 is provided at the end of the flexible circuit board 400 facing away from the display screen 100, and the flexible circuit board 400 is electrically connected to the first electrical device 200 or the second electrical device 300 through the plug connector 410.
[0029] In an optional embodiment of the present application, the electronic device may be a mobile phone with a folding function, and the display screen 100 may be a flexible display screen provided on the mobile phone with a folding function. Specifically, the housing of the electronic device includes a first housing and a second housing that are rotatably connected to each other, and the first housing and the second housing can be rotatably connected by structures such as hinges and rotating shafts. The flexible display screen is installed on the first housing and the second housing, and can switch between a folded state and an unfolded state as the first housing and the second housing rotate relative to each other. The flexible display screen includes a first part 101, a second part 102, and a flexible bending part 103 connecting the first part 101 and the second part 102, wherein the first part 101 is arranged opposite to the first housing, the second part 102 is arranged opposite to the second housing, and the flexible bending part 103 is arranged opposite to the hinge bending area between the first housing and the second housing.
[0030] The first electrical device 200 is arranged in a first space enclosed by the first shell and the display screen 100. The first electrical device 200 can be a main board of the electronic device. The second electrical device 300 is arranged in a second space enclosed by the second shell and the display screen 100. The second electrical device 300 can be a sub-board of the electronic device. The first electrical device 200 and the second electrical device 300 are electrically connected through the electrical connection part 110, and the electrical connection part 110 passes through the flexible bending part 103 of the flexible display screen. The communication between the main board and the sub-board can be achieved through the electrical connection part 110 integrated in the flexible display screen.
[0031] The electrical connection portion 110 can bend along with the flexible bending portion 103 of the flexible display screen, ensuring electrical connection without affecting the flexible display screen's bending performance. Furthermore, the presence of the electrical connection portion 110 eliminates the need for a flexible circuit board 400 in the hinge bending area of the electronic device to electrically connect the main board and sub-board. This saves space in the hinge bending area and eliminates the need to reserve space for the flexible circuit board 400, further enhancing the structural strength of the hinge. Furthermore, this prevents the flexible circuit board 400 from being easily damaged or failing after prolonged bending in the hinge bending area, thereby extending the lifespan of the electronic device.
[0032] Alternatively, the flexible display screen may be designed with multiple stacked layers, with the electrical connection portion 110 disposed between any two adjacent layers or within any layer. Depending on the location of the electrical connection portion 110 on the flexible display screen, a light-transmitting connection portion or a light-non-light-transmitting connection portion may be selected accordingly. For example, if the electrical connection portion 110 is located on the display side of the flexible display screen, the electrical connection portion 110 may be a light-transmitting connection portion. If the electrical connection portion 110 is located on the non-display side of the flexible display screen, the electrical connection portion 110 may be either a light-non-light-transmitting connection portion or a light-transmitting connection portion.
[0033] In an optional solution of the present application, the electrical connection part 110 is only arranged in the flexible bending part 103 of the flexible display screen. While saving the space of the hinge bending area, it avoids occupying too much space of the flexible display screen and reduces the impact on the display effect. A flexible circuit board 400 can be used in the non-flexible bending part 103, and the flexible circuit board 400 and the electrical connection part 110 are joined together and used together, which can also reduce costs.
[0034] In another optional solution of the present application, the electrical connection part 110 is arranged in the first part 101, the second part 102 and the flexible bending part 103 of the flexible display screen, that is, the electrical connection part 110 is set on the full screen of the flexible display screen, which can reduce the use of the flexible circuit board 400, further save the space in the internal cavity of the device, and is conducive to improving the lightness and thinness of the electronic device.
[0035] The above embodiments of this application focus on describing the differences between the various embodiments. As long as the different technical features between the various embodiments are not contradictory, they can be combined to form more specific embodiments. Considering the simplicity of the text, they will not be repeated here.
[0036] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can also make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which are within the protection of this application.
