Description

An electronic device

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on December 27, 2023, with application number 202311834479.4 and application name “An Electronic Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of terminal technology, and in particular to an electronic device. Background Art

[0003] Currently, in some electronic devices, the battery is located below the screen. To ensure that the screen components (e.g., the voltage-stabilizing capacitors for the screen power supply) are placed close to the screen chip, the screen components need to be stacked with the battery along the thickness of the electronic device.

[0004] When the screen device and the battery are stacked together, they occupy the battery's thickness, thereby reducing the battery's thickness. When the battery is thinner, the battery capacity is reduced, thus shortening the electronic device's standby time.

[0005] Summary of the Invention

[0006] An embodiment of the present application provides an electronic device that can prevent a screen device from occupying the thickness space of a battery, thereby avoiding reducing the thickness of the battery.

[0007] In a first aspect, an embodiment of the present application provides an electronic device, comprising: a screen and a shell, the screen and the shell being arranged relative to each other along the thickness direction of the electronic device to enclose a receiving cavity of the electronic device; a battery assembly, the battery assembly being arranged in the receiving cavity and stacked with the screen along the thickness direction; the battery assembly comprising a battery and a protective plate for the battery, at least a first portion of the protective plate being arranged on one side of the battery along a first direction, the first direction being perpendicular to the thickness direction; one or more screen devices, the screen device being electrically connected to the screen, and at least some of the one or more screen devices being stacked with the first portion of the protective plate along the thickness direction.

[0008] According to the embodiment of the present application, by stacking at least a portion of the screen device of the electronic device with the protection plate of the battery, the internal space of the electronic device is fully utilized, and the screen device is prevented from affecting the thickness of the battery, thereby extending the standby time of the electronic device.

[0010] In some embodiments of the present application, when the area of ​​the protective plate is not sufficient to accommodate all screen devices, a portion of the screen device can be stacked with the protective plate in the thickness direction, and the other portion does not overlap with the battery assembly in the thickness direction.

[0011] In a possible implementation of the first aspect above, the above-mentioned screen includes a display module and a screen chip provided on the display module, and the screen chip is located in the accommodating cavity; the first device and the second device are both electrically connected to the screen chip, and the distance between the first device and the screen chip is smaller than the distance between the second device and the screen chip; wherein, the first device is a power supply protection device of the screen, and the second device is a touch function control device of the screen.

[0012] In the embodiments of the present application, since some screen components need to be placed close to the screen chip, the screen components that need to be placed close to the screen chip can be used as first components and placed close to the screen chip. Meanwhile, some screen components that can be placed away from the screen chip can be used as second components and placed farther away from the screen chip. In other words, the distance between the first component and the screen chip is smaller than the distance between the second component and the screen chip.

[0013] In a possible implementation of the first aspect above, the first device is one of the following: a voltage-stabilizing capacitor of the screen power supply, a filter capacitor of the screen power supply; and / or the second device is one of the following: a touch chip, a touch protection device, a clock chip.

[0014] In a possible implementation of the first aspect, the electronic device includes a first circuit board and a second circuit board, the screen is electrically connected to the first circuit board through the second circuit board, and one or more screen devices are provided on the second circuit board.

[0015] For example, in an embodiment of the present application, a screen is connected to a first circuit board via a second circuit board. The first circuit board may be a motherboard of an electronic device, and the motherboard is electrically connected to the screen via the second circuit board to control the screen. The second circuit board may be a flexible circuit board to facilitate electrical connection between the motherboard and the screen.

[0016] In a possible implementation of the first aspect above, the screen chip, battery assembly and first circuit board are arranged in sequence along the length direction of the electronic device; wherein the first device is stacked with the protective plate, and the second device is stacked with the first circuit board.

[0020] In a possible implementation of the first aspect, the housing includes a third side wall and a fourth side wall that are oppositely arranged along a width direction of the electronic device, and an antenna of the electronic device is provided on the third side wall and / or the fourth side wall.

[0021] In a possible implementation of the first aspect above, the screen is a flexible screen, the screen includes a display portion and a bending portion connected to the display portion, the bending portion is located in the accommodating cavity, and the screen chip is provided on the bending portion.

[0022] For example, in some embodiments of the present application, the display portion or the bent portion of the screen needs to maintain a clearance distance from the side wall (such as the first side wall, the third side wall or the fourth side wall) where the antenna is provided. The screen chip is provided on the bent portion. Since the bent portion will take up a portion of the space, if the bent portion is provided on the side wall of the electronic device with an antenna, the black border area of ​​the screen will increase, thereby reducing the screen-to-body ratio of the screen. Therefore, the bent portion can be provided at a position close to the second side wall, and the antenna is not provided on the second side wall. Therefore, there is no need to maintain a large distance between the bent portion and the second side wall, thereby avoiding an increase in the black border area of ​​the screen and improving the screen-to-body ratio of the screen.

[0036] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0037] The present application provides an electronic device that fully utilizes the internal space of the electronic device by stacking at least a portion of the screen device of the electronic device with the protection plate of the battery, avoids the screen device from affecting the thickness of the battery, and thus extends the standby time of the electronic device.

[0038] In the embodiments of the present application, the electronic device may be a mobile phone, a tablet, a wearable device (e.g., a watch), a large-screen device, an augmented reality (AR) / virtual reality (VR) device, a personal digital assistant (PDA), or other electronic device with a display function, but this application does not limit this. The following describes a mobile phone as an example of an electronic device.

[0039] Figures 1A to 1C illustrate exemplary structural diagrams of an electronic device 100 provided in an embodiment of the present application. The electronic device 100 is a foldable device. Figure 1A illustrates a schematic diagram of the electronic device 100 in an unfolded state. Figure 1B illustrates a schematic diagram of the electronic device 100 in an intermediate state. Figure 1C illustrates a schematic diagram of the electronic device 100 in a folded state.

[0040] 1A to 1C , an electronic device 100 includes a first body 10, a second body 20, and a hinge mechanism 30. The first body 10 and the second body 20 are connected by the hinge mechanism 30, allowing the first body 10 and the second body 20 to rotate relative to each other, thereby enabling the electronic device to switch between a folded state and an unfolded state.

[0041] In the various figures herein, the X direction is the width direction of the first body 10 of the electronic device 100 (which can also be understood as the extension direction of the rotation axis of the hinge mechanism 30), the Y direction is the length direction of the first body 10 of the electronic device 100, and the Z direction is the thickness direction of the first body 10 of the electronic device 100. The X direction, the Y direction, and the Z direction can be perpendicular to each other. It can be understood that during the process of switching the electronic device 100 from the unfolded state to the folded state, the length of the electronic device 100 gradually decreases, while the thickness first increases and then decreases.

[0042] Exemplarily, the first body 10 includes a first inner screen 41, a first middle frame 11, and a screen 12. Along the Z direction, the first inner screen 41 and the screen 12 are located on opposite sides of the first middle frame 11. In this embodiment, the first inner screen 41 and the first middle frame 11 together form a first shell 50 (as an example of a shell of an electronic device) of the first body 10 of the electronic device 100. The first shell 50 and the screen 12 are arranged relative to each other along the Z direction to enclose a first receiving cavity (as an example of a receiving cavity of an electronic device) of the first body 10 of the electronic device 100. Exemplarily, the screen 12 can be fixed to the first shell 50 by bonding.

[0043] In other embodiments, the first housing 50 may also be formed in other ways. For example, in some embodiments, the first housing 50 may not include the first inner screen 41, but instead replace the first inner screen 41 with a back cover. In this embodiment, the first housing 50 may be formed by connecting the first middle frame 11 and the back cover. For another example, in other embodiments, the first housing 50 may include the first middle frame 11, the back cover, and the first inner screen 41, with the first middle frame 11 connected to the back cover, and the first inner screen 41 covering the back cover.

[0044] The second body 20 includes a second inner screen 42, a second middle frame 21, and a back cover 22. Along the thickness direction of the second body 20, the second inner screen 42 and the back cover 22 are located on opposite sides of the second middle frame 21. In this embodiment, the second body 20 may have a structure similar to that of the first body 10. For example, the second inner screen 42 and the second middle frame 21 together form a second housing 60 of the second body 20. The second housing 60 and the back cover 22 are disposed opposite each other along the thickness direction of the second body 20 to enclose a second receiving cavity of the second body 20 of the electronic device 100.

[0045] The first inner screen 41, the second inner screen 42, and the screen 12 can all be touch screens. In some embodiments, the first inner screen 41 and the second inner screen 42 can be two parts of the same flexible screen, and when the electronic device 100 is unfolded or folded, the flexible screen is unfolded or folded simultaneously. In other embodiments, the first inner screen 41 and the second inner screen 42 can also be two physically independent screens.

[0046] The screen 12 may be a flexible screen or a non-flexible screen. In some embodiments of the present application, the screen 12 may be an organic light-emitting diode (OLED) display, an active-matrix organic light-emitting diode (AMOLED) display, or the like, but this embodiment does not limit this.

[0047] The following describes the internal structure of the electronic device 100 using the first body 10 of the electronic device 100 as an example. The second body 20 of the electronic device 100 may have the same or similar structural distribution as the first body 10, or may have a different structure from the first body 10, which is not limited in this application.

[0048] It is understood that Figures 1A to 1C are merely exemplary illustrations of the structure of an electronic device, and the present application is not limited thereto. For example, in other embodiments, the electronic device 100 may also be a non-folding device, an external folding screen device, an internal folding screen device, a tri-folding device, etc. When the electronic device is a non-folding device, it may have a structure identical or similar to the first body 10 of the embodiment of the present application; when the electronic device is a folding device of another type, one of its bodies may have a structure identical or similar to the first body 10 of the embodiment of the present application.

[0049] To facilitate understanding, the exemplary structure of the first body 10' in the electronic device provided in some embodiments is first described with reference to Figures 2A and 2B. Figure 2A is a front view of the first body 10'. Figure 2B is a schematic cross-sectional view of the first body 10' (sectional view taken along line AA in Figure 2A). Figure 2C is a diagram of the internal structure of the first body 10' without the screen 12'.

[0050] Referring to Figures 2A and 2B , the first body 10' includes a housing 50', a screen 12', a battery 151', and a mainboard 14'. Along the Z-axis, the screen 12' is positioned over the housing 50', forming a housing cavity 13' with the housing 50'. Along the Y-axis, the battery 151' and mainboard 14' are positioned sequentially within the housing cavity 13'.

[0051] The screen 12' includes a display module 122' and a screen chip 123' disposed on the display module 122'. The screen chip 123' is located in the accommodating cavity 13' and is disposed close to the bottom wall 112' of the housing 50'.

[0052] The electronic device 100' also includes several screen components 18', each of which is electrically connected to the screen chip 123' (the electrical connection circuits are not shown in the figure). Because some screen components 18' (for example, the voltage-stabilizing capacitors for the screen 12' power supply) need to be connected close to the screen chip 123', the screen components 18' are placed in the position of the battery 151'. In other words, the screen components 18' are arranged to be stacked with the battery 151' along the Z direction.

[0053] It is understandable that because the screen device 18' needs to be stacked with the battery 13' in the Z direction, the thickness of the battery 13' (i.e., the height along the Z direction) will be reduced, resulting in a reduction in the capacity of the battery 13'. This reduces the standby time of the electronic device 100'. In addition, in some cases, to ensure the safety of the battery 13', the battery 13' and the screen device 18' need to have a certain avoidance distance in the thickness direction, which further reduces the thickness of the battery 13'.

[0054] To address the aforementioned issues, some embodiments of the present application provide an electronic device comprising a battery and a protective plate for protecting the battery. Furthermore, the present application laminates at least a portion of the screen component with the battery's protective plate to fully utilize the thickness of the protective plate to accommodate the screen component. This prevents the screen component from occupying battery space, eliminating the need to reduce the battery's size and thereby extending the electronic device's standby time.

[0055] The following describes an exemplary structure of the first body 10 of the electronic device 100 provided in an embodiment of the present application, with reference to Figures 3A to 3C. Figure 3A is a front view of the first body 10 of the electronic device 100. Figure 3B is a diagram of the internal structure of the first body 10 after removing the screen 12. Figure 3C is a cross-sectional view of the first body 10 (a cross-sectional view taken along line CC in Figure 3B).

[0056] In addition, for the sake of convenience of description, in this article, for each device inside the first body 10, the side of the device facing the screen 12 along the Z-axis direction is referred to as the "upper side" of the device, and the side of the device facing the first inner screen 41 along the Z-axis direction is referred to as the "lower side" of the device.

[0057] Referring to Figure 3A , as previously described, the first body 10 may include a first housing 50 (formed by connecting the middle frame 11 and the first inner screen 41) and a screen 12. Referring to Figures 3B to 3C , along the thickness direction of the first body 10 (e.g., the Z direction in Figure 3B ), the screen 12 and the first housing 50 are positioned opposite each other to enclose a first accommodating cavity 13 of the first body 10.

[0058] 3B and 3C , the middle frame 11 may include a first sidewall 111 and a second sidewall 112 disposed opposite each other along the Y direction, and a third sidewall 113 and a fourth sidewall 114 disposed opposite each other along the X direction. The first sidewall 111, the second sidewall 112, the third sidewall 113, the fourth sidewall 114, and the first inner screen 41 may collectively form the housing 50. Along the Z direction, the screen 12 is disposed over the first sidewall 111, the second sidewall 112, the third sidewall 113, and the fourth sidewall 114, thereby enclosing the first accommodating chamber 13 with the housing 50.

[0059] When a user is using the electronic device 100 (for example, when the user is viewing the display interface of the screen 12), the first side wall 111 may be located above the electronic device 100, the second side wall 112 may be located below the electronic device 100, the third side wall 113 may be located on the left side of the electronic device 100, and the fourth side wall 114 may be located on the right side of the electronic device 100. Therefore, for ease of description, the first side wall 111, the second side wall 112, the third side wall 113, and the fourth side wall 114 may be referred to as the top wall 111, the bottom wall 112, the left side wall 113, and the right side wall 114, respectively.

[0060] Among them, the antenna of the electronic device 100 can be set on the top wall 111, the left side wall 113 and / or the right side wall 114 to realize the wireless communication function between the electronic device 100 and other devices. Take the arrangement of the antenna on the left side wall 113 as an example. Referring to Figure 4, the left side wall 113 may include a metal layer 115 and a plastic layer 116 that are bonded to each other. In some embodiments, a pattern with a set shape can be processed on the metal layer 115 so that the pattern has the function of radiating electromagnetic waves in a specific frequency band, so that part of the structure of the left side wall 113 constitutes the antenna radiator of the electronic device 100. In other embodiments, the antenna radiator can also be fixed on the left side wall 113 as an independent component, thereby achieving the purpose of setting the antenna on the left side wall 113.

[0061] It is understood that in some embodiments, antennas may be disposed on all of the top wall 111, the left side wall 113, and the right side wall 114; in other embodiments, antennas may be disposed on one or both of the top wall 111, the left side wall 113, and the right side wall 114. Furthermore, when antennas are disposed on the left side wall 113 and / or the right side wall 114, the antennas may be disposed near the top of the first body 10 (i.e., closer to the top wall 111 than to the bottom wall 112).

[0062] 3B and 3C , in some embodiments of the present application, a first circuit board is further provided in the accommodating cavity 13. Exemplarily, the first circuit board may be the mainboard 14 of the electronic device. The mainboard 14 may, for example, include a printed circuit board (PCB) and components such as resistors, capacitors, inductors, diodes, transistors, field-effect transistors, interface devices, sensors, and integrated circuits arranged on the PCB. The mainboard 14 uses the above-mentioned devices to process internal and external signals and perform functional control of the electronic components of the electronic device 100, including display, charging, power on and off, functional applications, etc. In other embodiments, the first circuit board may also be other circuit boards other than the mainboard 14, such as a screen-specific circuit board, a sub-board of the electronic device 100, etc.

[0063] In some embodiments of the present application, the first accommodating cavity 13 is further provided with a battery assembly 15. The battery assembly 15 includes a battery 151 and a protective plate 152 for the battery 151. The protective plate 152 can be used to protect the battery 151, and can also be used to apply pressure to the contacts of the battery 151 to improve the electrical connection reliability of the battery 151. For example, the protective plate 152 may include a portion stacked with the battery 151 along the Z direction, and may also include a portion located on one side of the battery 151 along a first direction (the first direction is perpendicular to the Z direction, for example, the first direction is the X direction or the Y direction) (herein, this portion is referred to as the first portion 152a of the protective plate 152). It will be understood that the projection of the first portion 152a of the protective plate 152 along the Z direction does not overlap with the projection of the battery 151 along the Z direction. In addition, in some examples, referring to FIG. 3C , the thickness of the first portion 152a of the protective plate 152 (the dimension of the first portion along the Z direction) is less than the thickness of the battery 151 (the dimension of the battery along the Z direction). However, the present application is not limited to this. In other examples, the thickness of the first portion 152 a of the protection plate 152 may also be equal to or slightly greater than the thickness of the battery 151 .

[0064] In this embodiment, the battery 151 and the first portion of the protective plate 152 are arranged sequentially along the X direction (for example, FIG. 3B shows the first portion 152a of the protective plate 152 and the battery 151 from left to right). In other embodiments, the battery 151 and the first portion 152a of the protective plate 152 may also be arranged sequentially along other directions perpendicular to the Z direction, for example, along the Y direction. The embodiments of the present application do not limit the relative positions of the first portion 152a of the protective plate 152 and the battery 151.

[0065] 3A , the first body 10 further includes a screen 12. In this embodiment, the screen 12 may be a flexible screen, such as an OLED screen. Furthermore, the screen 12 may also have a touch function.

[0066] Figure 5A shows a view of the back side of the screen 12 (the side of the screen 12 facing the first accommodating cavity 13), and Figure 5B shows a cross-sectional view of EE in Figure 5A. Referring to Figures 5A and 5B, the screen 12 may include a cover plate 121 and a display module 122. The display module 122 includes a display portion 122a (or "AA") and a bent portion 122b (or "COP") that are interconnected. The display portion 122a is the portion of the display module 122 used to display images and receive user touch operations. It is usually exposed to the outside of the electronic device 100 and visible to the user. The display portion 122a may include a plurality of pixels arranged in an array, each pixel can display a different color, so that the display portion 122a can display a predetermined interface image. The bent portion 122b may be provided with wiring, and other devices in the electronic device 100 (for example, a motherboard, a display chip, etc.) can be electrically connected to the display portion 122a through the wiring to control the pixel array in the display portion 122a. The bending portion 122b is usually hidden inside the electronic device 100 and is not visible to the user. For example, the bending portion 122b can be located in the first accommodating cavity 13. In addition, as shown in Figure 5B, there is a distance H between the edge of the bending portion 122b and the edge of the display portion 122a. Here, H=H1+H2, H1 is the size of the non-bending area of ​​the bending portion 122b, and H2 is the maximum size required for the bending portion 122b to bend. H2 can be determined by the material and thickness of the bending portion 122b. The value of H can be between 0.9mm and 1.3mm. For example, in an embodiment of the present application, H is 1.1mm.

[0067] The screen 12 may also include a cover plate 121. The cover plate 121 may be, for example, a cover glass (CG), which covers the display portion 122a to protect it. In some embodiments, a polarizer and optical adhesive may be laminated between the cover plate 121 and the display module 122. The polarizer controls the propagation direction and polarization state of light, thereby enabling the screen 12 to adjust the display brightness and contrast.

[0068] Referring to Figure 5A, in the embodiment of the present application, the bending portion 122b is arranged at the bottom of the first body 10. That is, along the Y direction, the bending portion 122b is closer to the bottom wall 112 relative to the top wall 111. This is because, in order to improve the aesthetics of the electronic device 100, a black border area is provided between the edge of the display portion 122a and the middle frame 11 to shield the internal structure of the electronic device 100. As mentioned above, since antennas can be provided on the left side wall 113, the right side wall 114 and / or the top wall 111 of the middle frame 11, the display module 122 needs to maintain a clearance distance d from the left side wall 113, the right side wall 114 and / or the top wall 111 to avoid interference of the display module 122 with the antenna and affect the performance of the antenna.

[0069] Since the edge of the bending portion 122b is at a distance H from the edge of the display portion 122a, if the bending portion 19 is set at the top, left side or right side of the first body 10, the width w1 of the top black border area, the width w2 of the left black border area or the width w3 of the right black border area needs to be greater than or equal to d+H. In this way, the screen-to-body ratio of the screen 12 of the first body 10 of the electronic device 100 (for example, the proportion of the displayable area of ​​the screen 12 to the overall area of ​​the first body 10) is reduced, and the appearance is not beautiful enough.

[0070] In this embodiment, considering that no antenna is provided on the bottom wall 112, the bent portion 122b of the screen 12 is provided at the bottom of the first body. In this way, there is no need to reserve an antenna avoidance distance d between the bent portion 122b and the bottom wall 112, and the width w4 of the bottom black border area only needs to be greater than or equal to the bent portion size H. The width of the black border area in other positions (for example, the top black border area, the left black border area, or the right black border area) only needs to be greater than or equal to the antenna avoidance distance d. In this way, the width of the black border area of ​​the first body 10 can be reduced, the screen-to-body ratio of the first body 10 can be increased, and the aesthetics of the first body 10 of the electronic device 100 can be improved.

[0071] It is understood that positioning the bent portion 122b at the bottom of the first body 10 is merely an example. In other embodiments, if the black border area of ​​the first body 10 is not too large, or for other reasons, the bent portion 122b may also be positioned at other locations, such as the top or left side of the first body 10. The embodiments of the present application do not limit the position of the bent portion 122b.

[0072] Referring to Figure 5A in conjunction with Figure 3B , the screen 12 is electrically connected to the mainboard 14 via a second circuit board, allowing the screen 12 to receive control signals from the mainboard 14. In this embodiment, the second circuit board is a flexible printed circuit board (FPC) 17. For ease of illustration, the outline of the FPC is shown in dashed lines in Figure 3B . Referring to Figure 3B , the end of the bent portion 19 of the display module 122 of the screen 12 is electrically connected to the FPC 17. Furthermore, along the Z direction, the FPC 17 can be positioned between the mainboard 14 and the display module 122 (i.e., the FPC 17 can overlie the mainboard 14 and the battery module 15). Furthermore, the projection of the FPC 17 along the Z direction can at least partially overlap with the projections of the mainboard 14 and the battery module 15 along the Z direction.

[0073] Continuing with Figures 5A and 3B , in an embodiment of the present application, the screen 12 may further include a screen chip 123 (or "screen IC") electrically connected to the display module 122. The screen chip 123 may receive control instructions from the motherboard 14 and control the display unit 122a according to the control instructions. For example, the screen chip 123 may control the color and brightness of each pixel of the display unit 122a so that the display unit 122a can display a predetermined image.

[0074] The screen chip 123 can be arranged on the bent portion 122b. For example, the bent portion 122b has a surface facing away from the display portion 122a, and the screen chip 123 can be arranged on this surface. The screen chip 123 can be electrically connected to the wiring in the bent portion 122b, and can be electrically connected to the display portion 122a and the flexible circuit board 17 through the wiring of the bent portion 122b. It can be understood that in this embodiment, since the bent portion 122b is located at the bottom of the first body 10, the screen chip 123 is also located at the bottom of the first body 10 of the electronic device 100. That is, along the Y direction, the screen chip 123 is closer to the bottom wall 112 relative to the top wall 111.

[0075] In addition, as shown in Figure 3B, along the Y direction, the screen chip 123, the battery assembly 15 and the main board 14 can be arranged in sequence. For example, along the XY plane, the positions of the main board 14, the battery assembly 15 and the screen chip 123 do not overlap. However, the present application is not limited to this. In other embodiments, the screen chip 123, the battery assembly 15 and the main board 14 can also have other arrangements. For example, the battery assembly 15 and the main board 14 are arranged side by side along the X direction. In addition, there may be no middle frame panel isolation between the screen 12 and the main board 14, and between the screen 12 and the battery assembly 15.

[0076] In other embodiments, the screen 12 may not be a flexible screen. In this embodiment, the various components of the display module 122 of the screen 12 may be located on the same plane (i.e., the display module 122 does not include the bent portion 122b). In this embodiment, the screen chip 123 may not be disposed on the display module 122, but may be electrically connected to the display module 122 via other devices (e.g., a flexible circuit board).

[0077] Continuing with Figures 3B and 3C, in some embodiments of the present application, the electronic device 100 may further include one or more screen devices 18, each of which may be electrically connected to the screen 12 (for example, electrically connected to the display module 122 and / or the screen chip 123 of the screen 12). The screen device 18 may be located in the first accommodating cavity 13. For example, the screen device 18 may be disposed on the surface of the flexible circuit board 17 and electrically connected to the screen 12 through the flexible circuit board 17. In other embodiments, the screen device 18 may also be electrically connected to the screen 12 in other ways, for example, by enameled wire.

[0078] FIG6 shows an exemplary arrangement of the screen device 18. FIG6 is a DD cross-sectional view of FIG3B. For ease of observation, FIG6 uses a dotted line to enclose the first portion 152a of the protective plate 152.

[0079] Referring to Figure 6 in conjunction with Figures 3B and 3C , in this embodiment, at least a portion of the screen component 18 overlaps with the first portion 152a of the protective plate 152 along the Z direction. For example, the screen component 18 includes one or more first components 181, which may overlap with the first portion 152a of the protective plate 152. Specifically, the projection of the first component 181 along the Z direction at least partially overlaps with the projection of the first portion 152a of the protective plate 152 along the Z direction. In some embodiments, the entire projection of the first component 181 along the Z direction lies within the projection of the first portion 152a of the protective plate 152 along the Z direction; in other embodiments, the projection of the first component 181 along the Z direction only partially lies within the projection of the first portion 152a of the protective plate 152 along the Z direction. Alternatively, the projection of the first component 181 along the Z direction may not overlap with the projection of the battery 151 along the Z direction. Furthermore, the first component 181 may be stacked between the flexible circuit board 17 and the first portion 152a of the protective plate 152.

[0080] That is to say, in this embodiment, the thickness space where the protective plate 152 is located is fully utilized to arrange the screen device 18, which can avoid the screen device 18 occupying the thickness space of the battery 151 (that is, the projection of the screen device 18 along the Z direction and the projection of the battery 151 along the Z direction may not overlap), thereby avoiding reducing the thickness of the battery 151 and increasing the standby time of the electronic device 100.

[0081] In some embodiments, as shown in FIG6 , the thickness of the first portion 152a of the protective plate 152 may be less than the thickness of the battery 151. In this embodiment, the first device 181 may have a larger layout space. However, the present application is not limited thereto. In other embodiments, the thickness of the first portion 152a of the protective plate 152 may be substantially the same as or even slightly greater than the thickness of the battery 151. Since the required clearance distance between the protective plate 152 and the screen device 18 in the thickness direction is less than the clearance distance between the battery 151 and the screen device 18, even if the thickness of the first portion 152a is equal to or greater than the thickness of the battery 151, the space above the protective plate 152 may be used to arrange the screen device 18 to avoid the screen device 18 occupying the thickness space of the battery 151.

[0082] Furthermore, given the limited space above the protective plate 152 in some electronic devices 100, portions of the screen component 18 may be stacked with other components besides the battery assembly 15. For example, referring to Figures 3B, 3C, and 6, in some embodiments, the screen component 18 may further include one or more second components 182, the projection of which along the Z direction does not overlap with the battery assembly 15. For example, the second components 182 may be stacked with the mainboard 14 along the Z direction. For example, the second components 182 may be stacked between the mainboard 14 and the flexible circuit board 17.

[0083] It can be understood that in other embodiments, if the space above the first portion 152a of the protective plate 152 can accommodate all the screen devices 18, all the screen devices 18 can be stacked with the first portion 152a of the protective plate 152 along the Z direction.

[0084] In this embodiment, the first component 181 may be a power supply protection component for the screen 12, such as a voltage-stabilizing capacitor for the screen 12 power supply, a filter capacitor for the screen 12 power supply, etc. For example, the voltage-stabilizing capacitor for the screen 12 power supply may stabilize the power supply voltage, thereby improving the stability of the voltage input to the screen 12. The filter capacitor for the screen 12 power supply may filter high-frequency noise in the power supply, thereby improving the stability and reliability of the current input to the screen 12.

[0085] The second device 182 may be a touch control device for the screen 12, such as a touch chip, a touch protection device, a clock chip, etc. For example, the touch chip may process touch signals from the screen 12 and convert them into digital signals; the touch protection device may be used to protect the touch chip from static electricity damage; and the clock chip may be connected to multiple touch chips to synchronize their clocks.

[0086] In this embodiment, it is taken into account that the first device 181 is a device that needs to be connected closely to the screen chip 123. For example, when the voltage-stabilizing capacitor of the screen 12 power supply is far away from the screen chip, the voltage-stabilizing effect of the voltage-stabilizing capacitor will deteriorate, and the screen 12 will have problems such as horizontal stripes. Therefore, in this embodiment, the first device 181 is stacked with the protection plate 152, and the second device 182 is stacked with the main board 14, so that the distance between the first device 181 and the screen chip 123 is closer than the distance between the second device 182 and the screen chip 123. It can be understood that in other embodiments, when the main board 14 and the battery assembly 15 have other arrangements (for example, when the main board 14 is located below the battery assembly 15), the first device 181 can also be stacked with the main board 14, and the second device 182 can be stacked with the protection plate 152 of the battery 151.

[0087] In summary, the embodiments of the present application provide an electronic device that can avoid occupying the thickness space of the battery by stacking at least part of the screen device with the battery protection plate, thereby avoiding reducing the thickness of the battery and increasing the standby time of the electronic device.
