Description

Foldable electronic device and flexible display assembly thereof

Technical field

[0001] The present application relates to the technical field of electronic device structures with flexible screens, and in particular to a foldable electronic device and a flexible display screen assembly thereof. [Background Technology]

[0002] The gradual maturity of flexible display technology is driving significant changes in the way devices display displays. Foldable flexible screen phones are a key evolutionary direction for future mobile phone differentiation. Because their displays can flexibly switch between different display modes based on different usage scenarios, they are poised to become a key development direction for next-generation phones from mainstream device manufacturers. In the future, foldable flexible screen phones will undoubtedly become a major selling point for mobile devices.

[0003] Conventional solutions typically bond the folding screen module to the housing with double-sided tape. To prevent movement during the folding process, a gap is typically left between the sides of the folding screen module and the edges of the housing. To cover this gap and protect the edges of the folding screen module, decorative elements are required. The drawback of this solution is that the screen must be surrounded by a ring of decorative elements, which hinders the device's thinness and affects its feel. Furthermore, the presence of plastic parts around the screen detracts from the product's aesthetics.

[0060] Please refer to Figure 1, which is an enlarged schematic diagram of the local structure of the edge position of an electronic device of a conventional technical solution, wherein the folding screen module 101a is generally bonded to the shell 103a by double-sided tape 102a. In order to avoid the displacement of the folding screen module 101a during the folding process, a certain gap 104a is generally reserved between the side of the folding screen module 101a and the edge of the shell 103a. In order to block the gap 104a and protect the edge position of the folding screen module 101a, a decorative part 105a needs to be provided. The disadvantage of this technical solution is that a circle of decorative parts must be provided around the screen of the entire machine, which is not conducive to making the entire machine thin and affects the feel. In addition, there is a circle of plastic parts around the screen that affects the appearance of the product. In view of this, the embodiment of the present application provides a foldable electronic device.

[0061] Please refer to Figures 2 and 3 . Figure 2 is a schematic diagram of the structure of an embodiment of a foldable electronic device in the unfolded state, and Figure 3 is a schematic diagram of the structure of the electronic device in the embodiment of Figure 2 in the folded state. It should be noted that the electronic devices in this application may include mobile phones, tablet computers, laptop computers, wearable devices, and other electronic devices with foldable flexible displays. The electronic device 10 includes but is not limited to the following structures: a housing assembly 100 and a flexible display assembly 200.

[0062] Specifically, please refer to Figures 4 and 5 together. Figure 4 is a schematic diagram of the partial structural disassembly of an embodiment of the electronic device of the present application, and Figure 5 is a schematic diagram of the structural cross-section of the electronic device along line AA in the embodiment of Figure 1. The flexible display assembly 200 is connected to the shell assembly 100 and can be folded (state in Figure 3) or flattened (state in Figure 2) as the shell assembly 100 rotates relative to each other.

[0063] Optionally, please continue to refer to Figure 4. The shell assembly 100 in this embodiment includes a first shell 110, a second shell 120 and a shaft assembly 130; the first shell 110 and the second shell 120 are respectively connected to the shaft assembly 130, and the first shell 110 and the second shell 120 can rotate relative to each other around the shaft assembly 130; the detailed structure of the shaft assembly 130 is within the scope of understanding of those skilled in the art and will not be repeated here.

[0064] Please refer to Figure 6, which is an enlarged schematic diagram of the local structure of the edge position of the electronic device in an embodiment of the present application. The flexible display assembly 200 in this embodiment includes a stacked flexible cover plate 210 and a flexible display screen module 220. The area of ​​the flexible cover plate 210 is larger than the area of ​​the flexible display screen module 220. The opposite side edges of the flexible cover plate 210 (only one side is shown in the figure) extend outside the flexible display screen module 220 and are fixedly connected to the first shell 110 and the second shell 120, respectively.

[0065] During the folding process of the flexible display assembly 200 with the housing assembly 100 (i.e., when the electronic device is in the folded state compared to the unfolded state), the flexible cover 210 is fixed relative to the first housing 110 and the second housing 120, while the flexible display module 220 can shift relative to the first housing 110 and the second housing 120 (in the direction of the arrow in the figure). Please also refer to Figure 7, which is a schematic diagram of the electronic device in another state of the embodiment of Figure 6. A comparison of Figure 7 with Figure 6 shows that the flexible display module 220 has shifted relative to the first housing 110.

[0066] Optionally, please continue to refer to Figure 6. The opposite side edges of the flexible cover 210 in this embodiment are respectively bonded to the first shell 110 and the second shell 120 through the first adhesive layer 101; the flexible display screen module 220 is respectively bonded to the first shell 110 and the second shell 120 through the second adhesive layer 102, wherein the elastic modulus of the first adhesive layer 101 is greater than the elastic modulus of the second adhesive layer 102, that is, during the folding process of the electronic device, the flexible cover 210 does not displace or the displacement is small relative to the first shell 110 and the second shell 120, while the flexible display screen module 220 undergoes a larger displacement relative to the first shell 110 and the second shell 120.

[0067] Alternatively, referring to FIG6 , the flexible cover 210 in this embodiment may include a laminated protective film 211 (an explosion-proof film for the flexible glass 212, specifically a resin film) and flexible glass 212 (e.g., Ultra-Thin Glass, UTG glass). The protective film 211 and the flexible glass 212 are bonded together by an optical adhesive layer 213. The flexible display module 220 may include multiple layers for implementing the display function and a bottom support plate (specifically, a stainless steel plate). The detailed features of this part are within the purview of those skilled in the art and will not be further elaborated here.

[0068] Continuing with FIG5 , the electronic device in the embodiment of the present application may further include a functional device 400, wherein the functional device 400 may include a battery 410 and a circuit board 420, etc., wherein the functional device 400 (the battery 410 and the circuit board 420 shown in the figure) may be disposed within the accommodating cavity of the housing 100 (the first housing 110 and the second housing 120). Other structural features of the electronic device are within the purview of those skilled in the art and will not be listed or described in detail here.

[0069] Please refer to Figure 8, which is a schematic block diagram of the structure of an embodiment of an electronic device of the present application. The electronic device can be a foldable mobile phone, tablet computer, laptop computer, wearable device, etc. This embodiment is illustrated by taking a foldable mobile phone as an example. The structure of the electronic device 10 may include an RF circuit 910, a memory 920, an input unit 930, a display unit 940 (which can be the flexible display module 220 in the above embodiment), a sensor 950, an audio circuit 960, a wifi module 970, a processor 980 (which can be the circuit board 420 in the above embodiment) and a power supply 990 (which can be the battery 410 in the above embodiment). Among them, the RF circuit 910, the memory 920, the input unit 930, the display unit 940, the sensor 950, the audio circuit 960 and the wifi module 970 are respectively connected to the processor 980; the power supply 990 is used to provide power to the entire electronic device 10.

[0070] Specifically, the RF circuit 910 is used to receive and send signals; the memory 920 is used to store data instruction information; the input unit 930 is used to input information, which may specifically include a touch panel 931 and other input devices 932 such as operation buttons; the display unit 940 may include a display panel 941, etc.; the sensor 950 includes an infrared sensor, a laser sensor, etc., for detecting user proximity signals, distance signals, etc.; the speaker 961 and the microphone (or microphone) 962 are connected to the processor 980 through the audio circuit 960 for receiving and sending sound signals; the wifi module 970 is used to receive and transmit wifi signals, and the processor 980 is used to process data information of the electronic device. For the specific structural features of the electronic device, please refer to the relevant description of the above embodiment, which will not be described in detail here.

[0071] The foldable electronic device provided in the embodiment of the present application, by fixedly connecting the edge of the flexible cover plate to the shell, allows the flexible display screen module to be displaced relative to the shell, which can eliminate the design of decorative parts in the conventional technical solution, making the overall structure simpler. Please refer to Figure 9, which is a schematic diagram of the partial structure of the electronic device in the folded state in the conventional technical solution. Due to the presence of the decorative parts 105a, the gap 106a between the folding screen modules 101a of the electronic device is large when the electronic device is fully folded, and it is easy for the folding screen module 101a to be scratched by entering debris. In comparison, the electronic device in the embodiment of the present application, because the decorative parts are removed, has a smaller screen gap in the fully folded state, reducing the risk of debris entering between the display screens and improving the overall appearance of the product.

[0072] Conventional foldable screen phones all have a structure that uses magnets to hold the middle frame together after folding. However, the magnetic force still exists after opening, which can easily cause the magnets to attract other foreign objects during use, thereby causing damage to the screen. In view of this, the present application provides a structure for an electronic device in an embodiment.

[0073] Please refer to Figure 10, which is a schematic cross-sectional view of the partial structure of another embodiment of the electronic device of the present application, wherein a first magnetic part 111 is provided near the edge of the first shell 110 in this embodiment, and the first magnetic part 111 can be embedded in the installation groove, and the flexible display assembly 200 is covered on the first magnetic part 111. A first magnetic isolation sheet 201 is provided at the edge of the flexible display module 220; the relative displacement of the flexible display module 220 and the first shell 110 drives the first magnetic isolation sheet 201 to move, thereby achieving shielding and exposure of the first magnetic part 111. Please also refer to Figure 11, which is a schematic structural diagram of another state of displacement of the flexible display module of the electronic device in the embodiment of Figure 10, wherein Figure 10 shows a state in which the first magnetic part 111 is blocked, and Figure 11 shows a state in which the first magnetic part 111 is exposed.

[0074] Among them, the first magnetic shielding sheet 201 can be bonded to the supporting steel sheet at the bottom of the flexible display screen module 220 through the adhesive layer 103. In addition, a second magnetic part is provided near the edge of the second shell in this embodiment, and the flexible display screen assembly cover is provided on the second magnetic part; when the electronic device is fully folded, the second magnetic part is aligned and attracted to the first magnetic part. Among them, a second magnetic shielding sheet is provided at the edge of the flexible display screen module; the relative displacement of the flexible display screen module and the second shell drives the second magnetic shielding sheet to move, thereby realizing the shielding and exposure of the second magnetic part. Among them, the structure of the second magnetic shielding sheet and the second magnetic part is not shown in the figure, and its setting position and structural form are similar to the structure of the first magnetic shielding sheet and the first magnetic part in Figures 10 and 11, and the two groups of structures are symmetrically arranged on the opposite sides of the shell.

[0075] Since the flexible screen is protected inside in the combined state, it is not prone to adsorption damage. When the electronic device begins to unfold, the magnetic shielding sheet moves outward along with the flexible display module 220. At this time, the magnetic shielding sheet begins to shield and block the magnet. After the mobile phone is fully unfolded, the magnetic shielding sheet completely covers the magnet, thereby weakening the magnetic force. The magnetic shielding sheet only needs to be arranged in the local position where the magnetic parts are located, so as not to increase the thickness of the mobile phone screen. The displacement of the magnetic shielding sheet can be adjusted by adjusting the modulus of the adhesive backing (second adhesive layer 102) of the flexible display module 220 and the first shell 110 and the second shell 120, thereby ensuring that the magnetic shielding sheet has enough displacement to shield the magnetic parts after the electronic device is unfolded.

[0076] The electronic device in this embodiment utilizes the displacement of the flexible display screen module during the folding process, and adds a magnetic shielding sheet to the flexible display screen module to shield the magnet during the unfolding process, thereby reducing the magnetic force and improving the reliability of the folding screen during unfolding.

[0077] Please refer to Figures 12 and 13 together. Figure 12 is a schematic cross-sectional view of the local structure of another embodiment of the electronic device of the present application, and Figure 13 is an enlarged schematic view of the local structure at point B in Figure 12. Optionally, a magnetic body 2100 is provided at the edge of the flexible cover 210 in this embodiment. The magnetic body 2100 and the flexible display module 220 are provided on the same side of the flexible cover 210, and the magnetic body 2100 and the flexible display module 220 are arranged adjacent to each other, leaving a staggered avoidance gap 2001 for the flexible display module 220 to move between the two.

[0078] Among them, the flexible cover 210 in this embodiment can also be composed of a stacked protective film 211 and a flexible glass 212. Different from the previous embodiment, the thickness of the flexible glass 212 at the edge is greater than the thickness at the middle position. The thickness of the glass at the middle position needs to consider the bending performance, so it is generally about 0.03mm; there is no bending area in the edge area, and it can be made as thick as 0.5mm, which is equivalent to a conventional straight-line mobile phone. This design method can enhance the protection of the edge position.

[0079] Optionally, the magnetic body 2100 is provided corresponding to the location 2120 where the thickness of the edge of the flexible glass is greater. Optionally, the magnetic body 2100 in this embodiment includes magnetic powder 2101 and a wrapping layer 2102 provided on the periphery of the magnetic powder 2101. The magnetic powder 2101 can be coated on the flexible glass 212 by spraying or applying; the surface of the flexible glass 212 can be treated by applying a primer to increase the adhesion of the magnetic powder 2101; the wrapping layer 2102 protects the edge of the flexible glass 212 by coating and wrapping the magnetic powder 2101 and the location 2120 where the thickness of the flexible glass 212 is greater, while wrapping the magnetic powder 2101 to prevent the magnetic powder 2101 from moving after being affected by the external magnetic environment.

[0080] It should also be noted that, in some other embodiments, the structure of setting the magnetic body 2100 at the edge position of the flexible cover 210 may be a solution that does not rely on the displacement of the flexible display module 220 relative to the shell, and the role of the magnetic body 2100 is to eliminate the magnet set on the middle frame in the conventional solution.

[0081] The electronic device in this embodiment achieves the effect of combining the entire device together by spraying magnetic powder + wrapping layer on the external cover glass area. At the same time, the magnets originally on the middle frame can be eliminated to prevent the magnets from being attracted to the screen function area and damaging the screen function, thereby improving reliability.

[0082] Please refer to Figure 14, which is a schematic cross-sectional view of the partial structure of another embodiment of the electronic device of the present application. Different from the aforementioned embodiment, the flexible cover plate 210 in this embodiment is further provided with an ink blocking layer 214 near the edge between the protective film 211 and the flexible glass 212. The ink blocking layer 214 can be arranged on the same layer as the optical adhesive layer 213. In the thickness direction of the flexible display assembly 200, the setting area of ​​the magnetic powder 2101 (that is, the magnetic body) and the avoidance gap 2001 are blocked by the ink blocking layer 214, that is, covered by the ink blocking layer 214, so as to avoid affecting the appearance of the screen. At the same time, since the magnetic powder 2101 is distributed in the thicker area of ​​the flexible glass 212, even if foreign matter is adsorbed here when it is unfolded for use, since the thickness of the flexible glass 212 at this position is relatively thick and it is a non-functional area, it will not affect the overall function of the screen.
