Description

Technical Field

[0001] This application relates to the field of terminal equipment technology, and more particularly to an electronic device. Background Technology

[0002] Mobile electronic devices with large screens, such as tablets, are now widely used. Currently, tablets typically feature a flip-chip architecture, meaning the main body is a unibody metal casing, the battery is first glued to the casing with adhesive, and finally the screen is assembled onto the casing. To facilitate flipping and to prevent damage to the screen from battery expansion contact, sufficient clearance is usually maintained between the battery and the screen.

[0003] However, the existence of a large gap will increase the overall thickness of electronic devices, making it impossible to achieve the development of thinner electronic devices. Summary of the Invention

[0004] This application provides an electronic device to solve the problem that the overall thickness of the electronic device cannot be reduced due to the large gap between the battery and the screen.

[0005] In a first aspect, this application provides an electronic device, including: a housing, a mounting bracket, a battery, and a display screen. The mounting bracket is fixed to the housing and forms a receiving cavity with the housing; the battery includes an expandable surface capable of expansion, the battery is located in the receiving cavity, and is adhered to the mounting bracket with the expandable surface facing the housing; the display screen covers the mounting bracket and is fixed to the housing.

[0006] The electronic device provided in this application embodiment has a fixing bracket on the surface of the casing facing the display screen, and the battery is adhered to the fixing bracket with its expanded surface facing the casing. The fixing bracket isolates the battery from the display screen and prevents the battery from expanding towards the display screen. Thus, even if the electronic device is dropped and the battery shifts, the wrinkles in the battery's aluminum-plastic film will not push against the display screen, thereby preventing white patch damage to the display screen. Furthermore, it can reduce the gap between the display screen and the fixing bracket, as well as the expansion gap of the battery. Also, since the battery is not fixed to the casing, the thickness of the casing can be reduced. This reduces the overall thickness of the electronic device, achieving a thinner design and improving user experience.

[0007] Some implementations also include: a motherboard and a screen FPC located between the casing and the display screen; one end of the screen FPC is connected to the display screen, and the other end is connected to the motherboard; both the motherboard and the screen FPC are located on one side of the mounting bracket, and the projection of the screen FPC is outside the projection of the battery. This avoids the screen FPC occupying the space between the battery and the display screen, thereby reducing the overall thickness of the electronic device.

[0008] Some implementations also include: a motherboard, a USB mini-board, and a USB mini-board FPC located between the casing and the display screen; one end of the USB mini-board FPC is connected to the USB mini-board, and the other end is connected to the motherboard; both the motherboard and the USB mini-board FPC are located on one side of the mounting bracket, and the projection of the USB mini-board FPC is outside the projection of the battery. This avoids the USB mini-board FPC occupying the space between the battery and the display screen, thereby reducing the overall thickness of the electronic device.

[0009] In some implementations, the mounting bracket includes a frame with an opening at one end, and a plurality of lugs circumferentially disposed around the outer edge of the frame; the opening of the frame faces the housing, and the lugs are fixed to the housing, so that the frame and the housing form a receiving cavity. In this way, the mounting bracket and the housing can be used to form a cavity that can accommodate the battery, thereby isolating the battery from the display screen.

[0010] In some implementations, the surface of the housing facing the display screen includes a groove and multiple protrusions; the frame is located within the groove and forms a receiving cavity with the groove; multiple mounting ears correspond one-to-one with multiple protrusions, and the mounting ears are fixed to the corresponding protrusions by screws. In this way, the groove allows the battery to sink towards the housing side, thereby reducing the z-axis space of the electronic device and helping to reduce the thickness of the electronic device; the cooperation of the protrusions and mounting ears can improve the stability of the housing and the mounting bracket.

[0011] In some implementations, there is an expansion gap between the battery's expansion surface and the device housing. This expansion gap allows for the battery's normal expansion during use, and since the battery does not need to be fixed in the housing, the thickness of the housing can be reduced, thereby reducing the overall thickness of the electronic device.

[0012] In some implementations, the display screen includes a light guide plate, a first backlight group, and a second backlight group; the first and second backlight groups are arranged around the light guide plate. This allows the first and second backlight groups to be used to increase the screen brightness.

[0013] In some implementations, the light guide plate includes two opposing short sides; a first backlight group and a second backlight group are located on one side of the two short sides respectively; the first backlight group includes a first number of backlights, and the second backlight group includes a first number of backlights. This provides a way to improve screen brightness, applicable to various application scenarios.

[0014] In some implementations, the first backlight group is connected to the main chip via a first backlight chip; the second backlight group is connected to the main chip via a second backlight chip; and the main chip is located on the motherboard. In this way, the main chip can simultaneously control the first and second backlight groups to illuminate the light guide plate, thereby increasing screen brightness.

[0015] In some implementations, the light guide plate includes two opposing long sides; a first backlight group and a second backlight group are located on one side of the two long sides respectively; the first backlight group includes a second number of backlights, and the second backlight group includes a second number of backlights. This provides another way to improve screen brightness, applicable to different application scenarios.

[0016] In some implementations, the first backlight group includes a first sub-backlight group and a second sub-backlight group, each connected to the main chip via two first backlight chips; the second backlight group includes a third sub-backlight group and a fourth sub-backlight group, each connected to the main chip via two second backlight chips; the main chip is located on the motherboard. In this way, the main chip can simultaneously control the first and second backlight groups to illuminate the light guide plate, thereby increasing screen brightness.

[0017] In some implementations, the light guide plate includes adjacent short and long sides; a first backlight group is located on one side of the long side, and a second backlight group is located on one side of the short side; the first backlight group includes a second number of backlights, and the second backlight group includes a first number of backlights; the first number is less than the second number. This provides another way to improve screen brightness, applicable to various application scenarios.

[0018] In some implementations, the first backlight group includes a first sub-backlight group and a second sub-backlight group. The first and second sub-backlight groups are connected to the main chip via two first backlight chips, one for each other. The second backlight group is connected to the main chip via a second backlight chip. The main chip is located on the motherboard. In this way, the main chip can simultaneously control the first and second backlight groups to illuminate the light guide plate, thereby improving screen brightness.

[0019] Secondly, embodiments of this application also provide an electronic device, including: a housing, a display screen, and a battery. The display screen is fixed to the housing, and a support plate is included on the side of the display screen facing the housing; the battery includes an expandable surface capable of expansion, and the battery is adhered to the support plate with the expandable surface facing the housing.

[0020] The electronic device provided in this application attaches the battery to a support plate of the display screen with the expanded surface facing the device housing. The support plate prevents the battery from expanding towards the display screen, instead causing it to expand towards the device housing. This prevents wrinkles in the battery's aluminum-plastic film from pressing against the display screen even if the electronic device is dropped and the battery shifts, thus avoiding white patch damage to the display screen. Furthermore, it reduces the gap between the display screen and the battery, as well as the battery's expansion gap. Also, since the battery is not fixed to the device housing, the thickness of the device housing can be reduced. This reduces the overall thickness of the electronic device, achieving a thinner design and improving user experience.

[0021] Some implementations also include: a motherboard and a screen FPC located between the casing and the display screen; one end of the screen FPC is connected to the display screen, and the other end is connected to the motherboard; both the motherboard and the screen FPC are located on one side of the mounting bracket, and the projection of the screen FPC is outside the projection of the battery. This avoids the screen FPC occupying the space between the battery and the display screen, thereby reducing the overall thickness of the electronic device.

[0022] Some implementations also include: a motherboard, a USB mini-board, and a USB mini-board FPC located between the casing and the display screen; one end of the USB mini-board FPC is connected to the USB mini-board, and the other end is connected to the motherboard; both the motherboard and the USB mini-board FPC are located on one side of the mounting bracket, and the projection of the USB mini-board FPC is outside the projection of the battery. This avoids the USB mini-board FPC occupying the space between the battery and the display screen, thereby reducing the overall thickness of the electronic device.

[0023] In some implementations, there is an expansion gap between the battery's expansion surface and the device housing. This expansion gap allows for the battery's normal expansion during use, and since the battery does not need to be fixed in the housing, the thickness of the housing can be reduced, thereby reducing the overall thickness of the electronic device.

[0024] In some implementations, the support plate is made of steel. This increases the strength and rigidity of the support plate, thereby improving the support force of the display when the battery is bonded.

[0025] In some implementations, the display screen includes a light guide plate, a first backlight group, and a second backlight group; the first and second backlight groups are arranged around the light guide plate. This allows the first and second backlight groups to be used to increase the screen brightness.

[0026] In some implementations, the light guide plate includes two opposing short sides; a first backlight group and a second backlight group are located on one side of the two short sides respectively; the first backlight group includes a first number of backlights, and the second backlight group includes a first number of backlights. This provides a way to improve screen brightness, applicable to various application scenarios.

[0027] In some implementations, the first backlight group is connected to the main chip via a first backlight chip; the second backlight group is connected to the main chip via a second backlight chip; and the main chip is located on the motherboard. In this way, the main chip can simultaneously control the first and second backlight groups to illuminate the light guide plate, thereby increasing screen brightness.

In this way, the main chip can simultaneously control the first and second backlight groups to illuminate the light guide plate, thereby increasing screen brightness.

[0030] In some implementations, the light guide plate includes adjacent short and long sides; a first backlight group is located on one side of the long side, and a second backlight group is located on one side of the short side; the first backlight group includes a second number of backlights, and the second backlight group includes a first number of backlights; the first number is less than the second number. This provides another way to improve screen brightness, applicable to various application scenarios.

[0031] In some implementations, the first backlight group includes a first sub-backlight group and a second sub-backlight group. The first and second sub-backlight groups are connected to the main chip via two first backlight chips, one for each other. The second backlight group is connected to the main chip via a second backlight chip. The main chip is located on the motherboard.

[0061] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are all within the protection scope of this application.

[0062] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0063] Furthermore, in this application, directional terms such as "upper" and "lower" are defined relative to the orientation of the components shown in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the orientation of the components in the accompanying drawings.

[0064] The electronic devices described in this application include, but are not limited to, mobile phones, laptops, tablets, personal digital assistants, or wearable devices. The following description uses a tablet computer as an example.

[0065] Figure 1 This is a schematic diagram of the structure of the electronic device provided in the embodiments of this application.

[0066] like Figure 1 As shown, the electronic device may include a screen 10 and a battery cover 20, which are fastened together to form a complete cavity.

[0067] To facilitate the explanation of the positions of various components in the electronic device, this application embodiment exemplarily establishes a three-dimensional coordinate system based on the electronic device, wherein the x-axis direction is the width direction of the electronic device, the y-axis direction is the length direction of the electronic device, and the z-axis direction is the thickness direction of the electronic device.

[0068] Screen 10 is used to display an interface to present images or videos to the user. For example, screen 10 may be made of indium gallium zinc oxide (IGZO), low temperature polysilicon (LTPS), organic light-emitting diode (OLED), or thin film transistor liquid crystal display (TFT-LCD) made of amorphous silicon (A-si).

[0069] Figure 2 This is a schematic diagram of a screen structure.

[0070] like Figure 2 As shown, regardless of the type of screen used, screen 10 includes a light guide sheet 11 and a backlight assembly 12. The backlight assembly 12 is disposed on one side of the light guide sheet 11; for example, the backlight assembly 12 is disposed on the right short side of the light guide sheet 11. The backlight assembly 12 emits light into the light guide sheet 11, which receives and disperses the light evenly, transmitting it to the display layer of screen 10 to display images or videos.

[0071] Figure 3 This is a control circuit diagram for a backlight.

[0072] like Figure 3 As shown, the backlight assembly 12 includes 5 backlight channels, each containing 8 backlights, for a total of 40 backlights in the backlight assembly 12. The backlight assembly 12 is connected to the system-on-chip (SOC) 14 via an integrated circuit chip (IC) 13, and the SOC 14 controls the backlight assembly 12 to emit light, thereby illuminating the screen 10.

[0073] Different types of screens have different brightness levels. Mid-to-low-end screens use A-si, IGZO, or LTPS, with brightness ranging from 300 to 700 nits; high-end screens use OLED, with brightness reaching over 1000 nits.

[0074] Figure 4 This is a schematic diagram of the cross-sectional structure of an electronic device. Among them, Figure 4 Show Figure 1 Cross-sectional structure along the x-axis.

[0075] like Figure 4As shown, the battery cover 20 serves as the casing of the electronic device, supporting the screen 10 and protecting the internal components. Currently, most tablet computers use a flip-chip architecture; therefore, the battery cover 20 is a unibody metal casing.

[0076] The electronic device's internal cavity includes components such as a battery module 30, a communication module, a circuit board, a speaker assembly, and a camera assembly, which will not be listed here. The circuit board is the motherboard, and the backlight chip 13 and the system-on-a-chip 14 are integrated on the circuit board.

[0077] When using a flip-chip packaging architecture, the battery module 30 is first bonded to the battery cover 20 using adhesive, then other components are laid out, and finally the screen 10 is assembled onto the battery cover 20. To support the battery module 30, the battery cover 20 needs to have a certain thickness H. 20 For example, thickness H 20 It must be at least 0.6mm.

[0078] Figure 5 This is a partial structural diagram of a battery module and battery cover.

[0079] like Figure 5 As shown, various components are arranged within the overall cavity, each connected to the circuit board. For components located far apart, a flexible printed circuit board (FPC) is typically used to connect them to the circuit board. The FPC traces are usually routed above the battery module 30 to shorten the trace distance. The FPC includes a USB interface FPC 41 and a keyboard FPC 42. The USB interface FPC 41 connects the charging port of the electronic device to the circuit board to enable charging. The keyboard FPC 42 connects the keyboard interface to the circuit board to enable communication between the external keyboard and the electronic device, allowing the user to operate the electronic device using the keyboard.

[0080] Combination Figure 4 and Figure 5 As shown, there is no support frame separating the battery module 30 and the screen 10; only a portion of FPC and cushioning foam (not shown in the figure) are present. However, during the drop of the electronic device, the battery module 30 inevitably shifts, causing wrinkles in the aluminum-plastic film of the battery module 30. These wrinkles directly impact the screen 10, resulting in white patches of damage to the screen 10.

[0081] To prevent the creases of the battery module 30 from contacting the screen 10, a clearance L0 is required between the screen 10 and the battery module 30. This clearance L0 includes the distance between the screen 10 and the battery module 30 (approximately 0.5mm), the thickness of the FPC (approximately 0.15mm), and the expansion gap of the battery module 30 (approximately 0.15mm). In other words, the clearance L0 is approximately 0.8mm. Since the battery module 30 is adjacent to the screen 10, to prevent contact between the battery module 30 and the screen 10 after expansion, the expansion gap for the battery module 30 is designed to exceed the space required for normal expansion during normal use. The space required for normal expansion is approximately 0.1mm.

[0082] However, as electronic devices become thinner, the clearance L0 between the flip-chip battery module 30 and the screen 10, as well as the thickness H of the battery cover 20, become increasingly important. 20 These factors all contribute to thickness bottlenecks, resulting in excessively thick electronic devices and hindering the pursuit of thinner designs. Excessive thickness not only increases the weight of the device but also makes it inconvenient for users to operate. Furthermore, regardless of the screen type used, the screen 10 employs single-sided backlighting, which fails to meet user needs for brightness levels (300-700 nits) in mid-to-low-end devices. Clearly, existing electronic devices cannot satisfy user experience requirements.

[0083] To address the aforementioned technical problems, this application provides an electronic device that can prevent battery creases from damaging the screen when dropped, reduce the overall thickness of the device, and improve screen brightness to enhance user experience.

[0084] Figure 6 This is the first structural schematic diagram of the electronic device provided in the embodiments of this application.

[0085] like Figure 6 As shown, in some embodiments, the electronic device provided in this application may include: a housing 100, a mounting bracket 200, a battery 300, and a display screen 400.

[0086] The housing 100 can be a one-piece metal shell and can also serve as a battery cover, protecting the battery 300 and other internal components of the electronic device, as well as supporting the display screen 400.

[0087] The fixed bracket 200 is fixed to the housing 100 and together with the housing 100 forms a receiving cavity 201. For example, the fixed bracket 200 can be made of a metal material with a certain hardness and strength, such as stainless steel or steel sheet, to improve the supporting force.

[0088] Figure 7 This is a schematic diagram of the structure of the fixed bracket provided in the embodiment of this application.

[0089] like Figure 7 As shown, in some embodiments, the fixing bracket 200 may include a frame 202 with an opening at one end, and a plurality of lugs 203 circumferentially disposed around the outer edge of the frame 202.

[0090] The frame 202 includes a base plate and an annular sidewall (not shown in the figure). The annular sidewall is connected to the outer edge of the base plate at an angle (such as a vertical angle), making the frame 202 concave and providing a receiving space. Multiple hanging ears 203 are spaced apart on the outer edge of the base plate of the frame 202. The hanging ears 203 include through holes (not shown in the figure) to fix the fixing bracket 200 to the housing 100 by screws.

[0091] Figure 8 This is a partial structural diagram of the fixed bracket and the fuselage housing provided in the embodiments of this application.

[0092] like Figure 8 As shown in (a), in some embodiments, the opening of the frame 202 faces the housing 100, and the lug 203 is fixed to the housing 100 so that the frame 202 and the housing 100 form a receiving cavity 201.

[0093] For example, the thickness h1 of the fixed bracket 200 can be about 0.15 mm. Wherein, the thickness h1 can be the thickness of the base plate of the frame 202 along the z-axis direction.

[0094] like Figure 8 As shown in (b), the battery 300 is located within the receiving cavity 201 and is bonded to the mounting bracket 200 by an adhesive backing (not shown). For example, the thickness of the adhesive backing can be approximately 0.1 mm. The battery 300 and the mounting bracket 200 can be supplied separately for assembly on the electronic device production line, or they can be supplied as a single unit, eliminating the need for the Mylar film wrapping the battery 300 and reducing costs.

[0095] The battery 300 expands due to increased heat during charging or use, and this expansion is a whole-body expansion. However, since one surface of the battery 300 is adhered to the mounting bracket 200, this side surface is normally not expanded due to the resistance of the mounting bracket 200. Instead, the expansion occurs from the surface opposite to the adhered surface. This expanding surface is the expanding surface 301, which faces the housing 100. In other words, the battery 300 is adhered to the mounting bracket 200 with the expanding surface 301 facing the housing 100.

[0096] An expansion gap L1 is provided between the expansion surface 301 of the battery 300 and the housing 100. The expansion gap L1 is a reserved space for the normal expansion of the battery 300 during use. For example, the expansion gap L1 can be about 0.1mm. Since the battery 300 is blocked by the fixing bracket 200 and will not expand towards the display screen 400, the expansion gap L1 only needs to reserve the space required for normal expansion.

[0097] In some embodiments, the surface of the housing 100 facing the display screen 400 may include a groove 101 and a plurality of bosses (not shown).

[0098] The frame 202 is located within the groove 101 and forms a receiving cavity 201 with the groove 101. In this way, the area of ​​the housing 100 opposite to the battery 300 is thinned, allowing the battery 300 to sink towards the housing 100 side, thereby reducing the z-axis space of the electronic device and helping to reduce the thickness of the electronic device.

[0099] Multiple hanging ears 203 correspond one-to-one with multiple protrusions. The hanging ears 203 are fixed to the protrusions opposite to them by screws, so as to fix the fixing bracket 200 to the body housing 100.

[0100] It is understandable that the relative height between the fixed bracket 200 and the body housing 100 can be adjusted by setting different heights of the boss along the z-axis, thereby adjusting the distance between the expansion surface 301 of the battery 300 and the body housing 100, so that there is an expansion gap L1 between the expansion surface 301 and the body housing 100.

[0101] See you again Figure 6 The display screen 400 covers the mounting bracket 200 and is fixed to the housing 100. There is a tolerance gap L2 between the display screen 400 and the mounting bracket 200; for example, the tolerance gap L2 can be 0.3 mm. The tolerance gap L2 is the installation tolerance required when assembling the display screen 400 using a flip-chip architecture, and is much smaller than the reserved clearance L0 in conventional solutions.

[0102] Because the battery 300 is adhered to the mounting bracket 200, and the expanded surface 301 of the battery 300 faces the housing 100, even if the battery 300 expands and wrinkles, it will not damage the display screen 400. Furthermore, the housing 100 does not need to support the battery 300, thus reducing the thickness of the housing 100 and allowing for a reduction in the thickness h2 of the housing 100, thereby reducing the overall thickness of the electronic device. For example, the thickness h2 of the housing 100 can be 0.5 mm, resulting in a thickness gain of 0.1 mm compared to the thickness of the prior art battery cover 20 (0.6 mm). The thickness h2 of the housing 100 can refer to the overall thickness of the housing 100 or the thickness at the recess 101; this is not limited here.

[0103] Figure 9 This is a schematic diagram of the first internal structure of the electronic device provided in an embodiment of this application. Figure 9 The structure of the fuselage 100 is not shown.

[0104] like Figure 9 As shown, in some embodiments, the electronic device further includes components such as a motherboard 501, a screen FPC 502, a USB mini-board 503, and a USB mini-board FPC 504. The motherboard 501, screen FPC 502, USB mini-board 503, and USB mini-board FPC 504 are located between the housing 100 and the display screen 400.

[0105] The motherboard 501 integrates a system-on-chip (SOC), which is responsible for the main control logic of the electronic device and handles user requests. The USB mini-board 503 is a separate USB circuit board inside the electronic device, located near the charging port. The USB mini-board FPC 504 is used to connect the USB mini-board 503 (the charging port of the electronic device) to the motherboard 501 to enable the charging function of the electronic device.

[0106] One end of the screen FPC 502 is connected to the display screen 400, and the other end is connected to the motherboard 501. This allows the SOC on the motherboard 501 to control the display screen 400 to display images. Both the motherboard 501 and the screen FPC 502 are located on one side of the mounting bracket 200, and the projection of the screen FPC 502 is outside the projection of the battery 300. For example, the motherboard 501 is located at the top of the mounting bracket 200, and the screen FPC 502 is located on the right side of the mounting bracket 200. The projection of the screen FPC 502 does not overlap with the projection of the mounting bracket 200; that is, the wiring of the screen FPC 502 avoids the battery 300, preventing the screen FPC 502 from occupying the space between the battery 300 and the display screen 400.

[0107] One end of the USB mini-board FPC 504 is connected to the USB mini-board 503, and the other end is connected to the motherboard 501. This allows the charging port to be connected to the motherboard 501 for powering electronic devices. Both the motherboard 501 and the USB mini-board FPC 504 are located on one side of the mounting bracket 200, and the projection of the USB mini-board FPC 504 is outside the projection of the battery 300. For example, both the USB mini-board 503 and the USB mini-board FPC 504 are located on the left side of the mounting bracket 200. The projection of the USB mini-board FPC 504 does not overlap with the projection of the mounting bracket 200; that is, the wiring of the USB mini-board FPC 504 avoids the battery 300, preventing the USB mini-board FPC 504 from occupying the space between the battery 300 and the display screen 400.

[0108] The thickness of both the screen FPC 502 and the USB board FPC 504 is approximately 0.15mm, thus achieving a thickness gain of 0.15mm.

[0109] Table 1 shows a comparison of the overall thickness of the conventional stacking scheme and the stacking scheme of this application.

[0110] Referring to Table 1 below, the thickness of the electronic device in the stacking scheme provided in this application embodiment is compared with the thickness of the electronic device in the conventional stacking scheme.

[0111] Table 1 Comparison of overall thickness between conventional stacking schemes and the stacking scheme of this application

[0112] Screen gap FPC Expansion gap Fixed bracket Adhesive backing Battery Battery cover Total thickness Conventional stacking scheme 2.41 0.5 0.15 0.15 0 0.1 2.6 0.6 6.51 This application's stacking scheme 2.41 0.3 0 0.1 0.15 0.1 2.6 0.5 6.16

[0113] In the table, the unit is mm, and the value is the thickness occupied by each structure in the overall thickness of the electronic device. The value "0" indicates that the structure does not occupy the overall thickness.

[0114] In a conventional stacking scheme, the gap (distance) between the screen 10 and the battery module 30 is 0.5mm, the thickness of the FPC is 0.15mm, and the expansion gap of the battery module 30 is 0.15mm, meaning the reserved clearance L0 is 0.8mm. The thickness of the battery cover 20 is 0.6mm. No fixing bracket 200 is provided. Thus, the overall thickness of the electronic device is 6.51mm.

[0115] In the stacking scheme of this application, there is a tolerance gap L2 of 0.3mm between the display screen 400 and the fixing bracket 200; the thickness of the fixing bracket 200 is 0.15mm; the expansion gap of the battery 300 is 0.1mm; the thickness of the housing 100 is 0.5mm; and the thickness of the FPC is 0.15mm, but the FPC is not placed between the display screen 400 and the battery 300, so the thickness occupied by the FPC is 0. Thus, the overall thickness of the electronic device is 6.16mm.

[0116] By comparing the thickness of the electronic device of the present application embodiment with that of a conventional electronic device, the overall thickness of the electronic device of the present application embodiment can be reduced by 0.35 mm.

[0117] The electronic device provided in this application embodiment has a fixing bracket 200 provided on the surface of the housing 100 facing the display screen 400. The battery 300 is adhered to the fixing bracket 200 with its expansion surface 301 facing the housing 100. The fixing bracket 200 isolates the battery 300 from the display screen 400 and prevents the battery 300 from expanding towards the display screen 400. Thus, even if the electronic device is dropped and the battery 300 shifts, the wrinkles in the aluminum-plastic film of the battery 300 will not push against the display screen 400, thereby preventing white patch damage to the display screen 400. Furthermore, it can reduce the gap between the display screen 400 and the fixing bracket 200 and the expansion gap of the battery 300. Also, since the battery 300 is not fixed to the housing 100, the thickness of the housing 100 can be reduced. This reduces the overall thickness of the electronic device, achieving a thinner design and improving user experience.

[0118] Figure 10 This is a second structural schematic diagram of the electronic device provided in the embodiments of this application.

[0119] like Figure 10 As shown, in some embodiments, the electronic device provided in this application may include: a housing 100, a battery 300, and a display screen 400.

[0120] and Figure 6 The difference in the electronic device shown is that the electronic device provided in this application embodiment does not include the fixing bracket 200, and the battery 300 is directly attached to the display screen 400. Other contents can be referred to. Figure 6 The contents of the electronic device shown are not described here.

[0121] Figure 11 This is a schematic diagram of the stacked structure of the display screen provided in the embodiment of this application.

[0122] like Figure 11 As shown, in some embodiments, the display screen 400 may include a support sheet 410, a backlight module 420, a display panel 430, and a glass cover 440 stacked in sequence.

[0123] A glass cover plate 440 is bonded to one surface of the display panel 430 using optically clear adhesive (OCA) 431. An upper polarizer (not shown) is also bonded between the display panel 430 and the glass cover plate 440. A backlight module 420 is bonded to the other surface of the display panel 430, and a support sheet 410 is bonded to the back side of the backlight module 420. The support sheet 410 can be recessed to provide a receiving space. The backlight module 420 is disposed within the receiving space of the support sheet 410, and the display panel 430 is bonded to the edge of the recess in the support sheet 410.

[0124] The backlight module 420 includes a lower polarizer 406, a brightness enhancement film 405, a diffuser 404, a light guide plate 401, a reflector 407, a backlight (including a first backlight group 402 and a second backlight group 403), and a backlight FPC 408. The lower polarizer 406, the brightness enhancement film 405, the diffuser 404, the light guide plate 401, and the reflector 407 are bonded together in sequence. The backlight is disposed around the light guide plate 401. The backlight FPC 408 is bonded between the backlight and the support plate 410. The reflector 407 is bonded between the light guide plate 401 and the support plate 410.

[0125] The support plate 410 is made of stainless steel, such as steel sheet, to improve the strength and hardness of the support plate 410, thereby improving the support of the display screen 400.

[0126] Figure 12 This is a partial structural schematic diagram of the electronic device provided in the embodiments of this application.

[0127] Combination Figure 11 and Figure 12 As shown, the battery 300 is bonded to the support piece 410 of the display screen 400. The surface of the battery 300 bonded to the support piece 410 does not expand due to the resistance of the support piece 410; instead, expansion occurs from the surface opposite to the bonding surface. This expanding surface is the expanding surface 301, which faces the housing 100. In other words, the battery 300 is bonded to the support piece 410 with the expanding surface 301 facing the housing 100. For example, the adhesive can be a backing adhesive with a thickness of approximately 0.1 mm.

[0128] An expansion gap L1 is provided between the expansion surface 301 of the battery 300 and the housing 100. The expansion gap L1 is a reserved space for the normal expansion of the battery 300 during use. For example, the expansion gap L1 can be about 0.1 mm.

[0129] The surface of the housing 100 facing the display screen 400 may include a groove 101. The area of ​​the housing 100 opposite to the battery 300 is thinned so that the battery 300 can sink towards the housing 100 side, thereby reducing the z-axis space of the electronic device and helping to reduce the thickness of the electronic device.

[0130] Since the battery 300 is directly bonded to the display screen 400, and the expanded surface 301 of the battery 300 faces the housing 100, no clearance is needed between the battery 300 and the display screen 400, thus achieving thickness gains in this area. Even if the battery 300 wrinkles, it will not obscure the display screen 400. Furthermore, the housing 100 does not need to support the battery 300, so the thickness of the housing 100 does not need to be excessive, allowing for a reduction in the thickness h2 of the housing 100, thereby reducing the overall thickness of the electronic device. For example, the thickness h2 of the housing 100 can be 0.5 mm, thus achieving a thickness gain of 0.1 mm compared to the thickness of the battery cover 20 in a conventional solution.

[0131] Figure 13 This is a second internal structure diagram of the electronic device provided in an embodiment of this application. Wherein, Figure 13 The structure of the fuselage 100 is not shown.

[0132] like Figure 13 As shown, in some embodiments, the electronic device further includes components such as a motherboard 501, a screen FPC 502, a USB mini-board 503, and a USB mini-board FPC 504. The motherboard 501, screen FPC 502, USB mini-board 503, and USB mini-board FPC 504 are located between the housing 100 and the display screen 400.

[0133] One end of the screen FPC 502 is connected to the display screen 400, and the other end is connected to the motherboard 501. This allows the SOC on the motherboard 501 to control the display screen 400 to display images. Both the motherboard 501 and the screen FPC 502 are located on one side of the mounting bracket 200, and the projection of the screen FPC 502 is outside the projection of the battery 300. For example, the motherboard 501 is located at the top of the mounting bracket 200, and the screen FPC 502 is located on the right side of the mounting bracket 200. The projection of the screen FPC 502 does not overlap with the projection of the mounting bracket 200; that is, the wiring of the screen FPC 502 avoids the battery 300, preventing the screen FPC 502 from occupying the space between the battery 300 and the display screen 400.

[0134] One end of the USB mini-board FPC 504 is connected to the USB mini-board 503, and the other end is connected to the motherboard 501. This allows the charging port to be connected to the motherboard 501 for powering electronic devices. Both the motherboard 501 and the USB mini-board FPC 504 are located on one side of the mounting bracket 200, and the projection of the USB mini-board FPC 504 is outside the projection of the battery 300. For example, both the USB mini-board 503 and the USB mini-board FPC 504 are located on the left side of the mounting bracket 200. The projection of the USB mini-board FPC 504 does not overlap with the projection of the mounting bracket 200; that is, the wiring of the USB mini-board FPC 504 avoids the battery 300, preventing the USB mini-board FPC 504 from occupying the space between the battery 300 and the display screen 400.

[0135] The thickness of both the screen FPC 502 and the USB board FPC 504 is approximately 0.15mm, thus achieving a thickness gain of 0.15mm.

[0136] Table 2 shows a comparison of the overall thickness of the conventional stacking scheme and the stacking scheme of this application.

[0137] Referring to Table 2 below, compare the thickness of the electronic device with that of the stacking scheme provided in this application embodiment and that of the electronic device with that of the conventional stacking scheme.

[0138] Table 2 Comparison of overall thickness between conventional stacking schemes and the stacking scheme of this application

[0139] Screen gap FPC Expansion gap Adhesive backing Battery Battery cover Total thickness Conventional stacking scheme 2.41 0.5 0.15 0.15 0.1 2.6 0.6 6.51 This application's stacking scheme 2.41 0 0 0.1 0.1 2.6 0.5 5.71

[0140] In the table, the unit is mm, and the value is the thickness occupied by each structure in the overall thickness of the electronic device. The value "0" indicates that the structure does not occupy the overall thickness.

[0141] In a conventional stacking scheme, the gap (distance) between the screen 10 and the battery module 30 is 0.5mm, the thickness of the FPC is 0.15mm, the expansion gap of the battery module 30 is 0.15mm, and the reserved clearance L0 is 0.8mm. The thickness of the battery cover 20 is 0.6mm. Thus, the overall thickness of the electronic device is 6.51mm.

[0142] In the stacking scheme of this application, the gap between the display screen 400 and the battery 300 is 0; the expansion gap of the battery 300 is 0.1mm; the thickness of the housing 100 is 0.5mm; the thickness of the FPC is 0.15mm, but the FPC is not placed between the display screen 400 and the battery 300, so the thickness occupied by the FPC is 0. Thus, the overall thickness of the electronic device is 5.71mm.

[0143] By comparing the thickness of the electronic device of the present application embodiment with that of a conventional electronic device, the overall thickness of the electronic device of the present application embodiment can be reduced by 0.8 mm.

[0144] The electronic device provided in this application embodiment has a battery 300 bonded to a support piece 410 of a display screen 400 with its expansion surface 301 facing the housing 100. The support piece 410 prevents the battery 300 from expanding towards the display screen 400; instead, the battery 300 expands towards the housing 100. This prevents the battery 300 from shifting due to a drop, thus preventing wrinkles in the aluminum-plastic film of the battery 300 from pressing against the display screen 400 and causing white patch damage. Furthermore, it reduces the gap between the display screen 400 and the battery 300, as well as the expansion gap of the battery 300. Also, since the battery 300 is not fixed to the housing 100, the thickness of the housing 100 can be reduced. This reduces the overall thickness of the electronic device, achieving a thinner design and improving user experience.

[0145] In some embodiments, this application also provides an electronic device that improves the screen brightness of the display screen 400 by providing multiple sets of backlights in the backlight module 420 of the display screen 400.

[0146] It should be noted that this method of increasing screen brightness can be applied to... Figure 4 or Figure 8 The details of the electronic device provided in any embodiment are not elaborated here.

[0147] Figure 14 This is the first structural schematic diagram of the display screen provided in the embodiments of this application.

[0148] Combination Figure 11 and Figure 14 As shown, the backlight module 420 of the display screen 400 may include a light guide plate 401, a first backlight group 402, and a second backlight group 403. The first backlight group 402 and the second backlight group 403 are arranged around the light guide plate 401.

[0149] The light guide plate 401 may include two opposing short sides 4011, with the first backlight group 402 and the second backlight group 403 located on one side of each of the two short sides 4011. For example, the first backlight group 402 is located on one side of the left short side 4011 of the light guide plate 401, and the second backlight group 403 is located on one side of the right short side 4011 of the light guide plate 401.

[0150] Figure 15 This is the first structural schematic diagram of the light guide plate and backlight assembly provided in the embodiments of this application.

[0151] like Figure 15As shown, the light guide plate 401 operates on the following principle: The light guide plate 401 utilizes optical-grade acrylic / PC sheet material, employing a high-tech material with extremely high refractive index and no light absorption. Light guide points are printed onto the bottom surface of the optical-grade acrylic sheet using laser engraving, V-shaped cross-grid engraving, and UV screen printing technology. The optical-grade acrylic sheet absorbs light emitted from the backlight assembly and retains it on its surface. When light strikes each light guide point, the reflected light diffuses in various angles, breaking the reflection conditions and exiting from the front of the light guide plate 401. Through various density and size light guide points, the light guide plate 401 can emit light uniformly. Combined with… Figure 11 The reflector 407 is located at the bottom of the light guide plate 401. The purpose of the reflector 407 is to reflect the light exposed on the bottom surface back into the light guide plate 401 to improve the efficiency of light use.

[0152] Based on the aforementioned light guiding principle, the first backlight group 402 emits light to the right to enter the light guide plate 401, and the second backlight group 403 emits light to the left to enter the light guide plate 401. The first backlight group 402 and the second backlight group 403 are at the same height as the light guide plate 401, so that the light guide plate 401 can receive all the light from the first backlight group 402 and the second backlight group 403.

[0153] The first backlight group 402 and the second backlight group 403 simultaneously illuminate the same light guide plate 401. The light guide plate 401 directs the light upward to the display panel 430 side to improve the screen brightness of the display screen 400.

[0154] Figure 16 This is the first control circuit diagram of the backlight provided in the embodiments of this application.

[0155] like Figure 16 As shown, the first backlight group 402 is connected to the main chip 507 through the first backlight chip 505; the second backlight group 403 is connected to the main chip 507 through the second backlight chip 506. The main chip 507 can be a system-on-a-chip (SOC) and is integrated on the motherboard 501.

[0156] The first backlight chip 505, the second backlight chip 506, and the main chip 507 are located on the motherboard 501. Figure 11 The first backlight group 402 can be connected to the first backlight chip 505 through the corresponding backlight FPC 408, and the second backlight group 403 can be connected to the second backlight chip 506 through the corresponding backlight FPC 408.

[0157] The first backlight group 402 includes a first number of backlights, wherein the first backlight group 402 includes 5 backlight channels, each channel including 8 backlights. The second backlight group 403 includes a first number of backlights, wherein the second backlight group 403 includes 5 backlight channels, each channel including 8 backlights. For example, the first number is 40 backlights.

[0158] The electronic device provided in this application embodiment includes a first backlight group 402 and a second backlight group 403 disposed in the backlight module 420 of the display screen 400. The first backlight group 402 and the second backlight group 403 are located on the two short sides 4011 of the light guide plate 401. By increasing the number of backlight groups in the backlight module 420 and disposing of them in different positions, the screen brightness of the display screen 400 can be improved to meet user experience requirements. For example, by disposing of a first backlight group 402 and a second backlight group 403 including a first number of backlights, the screen brightness of the display screen 400 can reach 800 nits.

[0159] Figure 17 This is a second structural schematic diagram of the display screen provided in the embodiments of this application.

[0160] like Figure 17 As shown, the display screen 400 provided in this embodiment of the application is similar to... Figure 14 The difference between the displayed screen 400 and the one shown is that the positions and numbers of the first backlight group 402 and the second backlight group 403 are different; all other details are the same. Figure 14 The content of the display screen 400 shown is not described in detail here.

[0161] In this embodiment, the light guide plate 401 includes two opposing long sides 4012, and the first backlight group 402 and the second backlight group 403 are located on one side of the two long sides 4012 respectively. For example, the first backlight group 402 is located on one side of the upper long side 4012 of the light guide plate 401, and the second backlight group 403 is located on one side of the lower long side 4012 of the light guide plate 401.

[0162] Combination Figure 15 and Figure 17 Based on the light guiding principle of the light guide plate 401, the first backlight group 402 emits light downwards to enter the light guide plate 401, and the second backlight group 403 emits light upwards to enter the light guide plate 401. The first backlight group 402 and the second backlight group 403 are at the same height as the light guide plate 401, so that the light guide plate 401 can receive all the light from the first backlight group 402 and the second backlight group 403.

[0163] The first backlight group 402 and the second backlight group 403 simultaneously illuminate the same light guide plate 401. The light guide plate 401 directs the light upward to the display panel 430 side to improve the screen brightness of the display screen 400.

[0164] Figure 18 This is the second control circuit diagram of the backlight provided in the embodiments of this application.

[0165] like Figure 18 As shown, the number of backlights included in the first backlight group 402 and the second backlight group 403 is greater when they are arranged on the long side 4012 than when they are arranged on the short side 4011. However, the output current of a single backlight chip is limited and cannot control a large number of backlights simultaneously. Therefore, based on the upper limit of the backlight chip's current output, the first backlight group 402 can be divided into multiple groups, and the second backlight group 403 can be divided into two groups, with each small backlight group controlled by a single backlight chip.

[0166] The first backlight group 402 includes a first sub-backlight group 4021 and a second sub-backlight group 4022. The first sub-backlight group 4021 and the second sub-backlight group 4022 are connected to the main chip 507 via two first backlight chips 505, each corresponding to the first backlight group 4021. The second backlight group 403 includes a third sub-backlight group 4031 and a fourth sub-backlight group 4032. The third sub-backlight group 4031 and the fourth sub-backlight group 4032 are connected to the main chip 507 via two second backlight chips 506, each corresponding to the first backlight group 4021. This ensures that each sub-backlight group is controlled by its corresponding backlight chip, preventing the backlight chip from failing due to excessive output current.

[0167] The first backlight chip 505, the second backlight chip 506, and the main chip 507 are located on the motherboard 501. Figure 11 The first backlight group 402 is connected to the first backlight chip 505 through the corresponding backlight FPC 408, and the second backlight group 403 is connected to the second backlight chip 506 through the corresponding backlight FPC 408.

[0168] The first backlight group 402 includes a second number of backlights, wherein the first sub-backlight group 4021 and the second sub-backlight group 4022 each include 6 backlight channels, each channel including 6 backlights. The second backlight group 403 includes a second number of backlights, wherein the third sub-backlight group 4031 and the fourth sub-backlight group 4032 each include 6 backlight channels, each channel including 6 backlights. For example, the second number is 72 backlights.

[0169] The electronic device provided in this application embodiment includes a first backlight group 402 and a second backlight group 403 disposed in the backlight module 420 of the display screen 400. The first backlight group 402 and the second backlight group 403 are located on the two long sides 4012 of the light guide plate 401. By increasing the number of backlight groups in the backlight module 420 and disposing of them in different positions, the screen brightness of the display screen 400 can be improved to meet user experience requirements. For example, by disposing of a first backlight group 402 and a second backlight group 403 including a second number of backlights, the screen brightness of the display screen 400 can reach 720-1440 nits, where the second number is greater than the first number.

[0170] Figure 19 This is a third structural schematic diagram of the display screen provided in the embodiments of this application.

[0171] like Figure 19 As shown, the display screen 400 provided in this embodiment of the application is similar to... Figure 14 The difference between the displayed screen 400 and the one shown is that the positions and numbers of the first backlight group 402 and the second backlight group 403 are different; all other details are the same. Figure 14 The content of the display screen 400 shown is not described in detail here.

[0172] In this embodiment, the light guide plate 401 includes adjacent short sides 4011 and long sides 4012. The first backlight group 402 is located on one side of the long side 4012, and the second backlight group 403 is located on one side of the short side 4011. For example, the first backlight group 402 is located on one side of the lower long side 4012 of the light guide plate 401, and the second backlight group 403 is located on one side of the right short side 4011 of the light guide plate 401.

[0173] Figure 20 This is a second structural schematic diagram of the light guide plate and backlight assembly provided in the embodiments of this application.

[0174] like Figure 20 As shown, based on the light guiding principle of the light guide plate 401, the first backlight group 402 emits light upwards to enter the light guide plate 401, and the second backlight group 403 emits light to the left to enter the light guide plate 401. The first backlight group 402 and the second backlight group 403 are at the same height as the light guide plate 401, so that the light guide plate 401 can receive all the light from the first backlight group 402 and the second backlight group 403.

[0175] The first backlight group 402 and the second backlight group 403 simultaneously illuminate the same light guide plate 401, which directs the light to the display panel 430 side to improve the screen brightness of the display screen 400.

[0176] Figure 21This is the third control circuit diagram of the backlight provided in the embodiments of this application.

[0177] like Figure 21 As shown, the first backlight group 402 includes a first sub-backlight group 4021 and a second sub-backlight group 4022. The first sub-backlight group 4021 and the second sub-backlight group 4022 are connected to the main chip 507 through two first backlight chips 505, respectively. The second backlight group 403 is connected to the main chip 507 through a second backlight chip 506. In this way, it can be ensured that each sub-backlight group is controlled by a corresponding backlight chip, avoiding the situation where the backlight chip fails due to excessive output current.

[0178] The first backlight chip 505, the second backlight chip 506, and the main chip 507 are located on the motherboard 501. Figure 11 The first sub-backlight group 4021 and the second sub-backlight group 4022 are connected to the first backlight chip 505 through the corresponding backlight FPC 408, and the second backlight group 403 can be connected to the second backlight chip 506 through the corresponding backlight FPC 408.

[0179] The first backlight group 402 includes a second number of backlights, wherein both the first sub-backlight group 4021 and the second sub-backlight group 4022 include 6 backlight channels, each channel including 6 backlights. For example, the second number is 72 backlights. The second backlight group 403 includes a first number of backlights, which is less than the second number, wherein the second backlight group 403 includes 5 backlight channels, each channel including 8 backlights. For example, the first number is 40 backlights.

[0180] The electronic device provided in this application embodiment includes a first backlight group 402 and a second backlight group 403 disposed in the backlight module 420 of the display screen 400. The first backlight group 402 and the second backlight group 403 are located on the adjacent short side 4011 side and long side 4012 side of the light guide plate 401. By increasing the number of backlight groups in the backlight module 420 and disposing of them in different positions, the screen brightness of the display screen 400 can be improved to meet user experience requirements. For example, by disposing of a first backlight group 402 including a second number of backlights and a second backlight group 403 including a first number of backlights, the screen brightness of the display screen 400 can reach 800-1120 nits.

[0181] The electronic device provided in this application embodiment can increase the screen brightness of a low-to-mid-range screen by increasing the number of backlight lamps in the backlight module 420 and setting them in different positions. Even if the display screen 400 uses a low-to-mid-range screen, its screen brightness can still exceed the original screen brightness (300-700 nits) of the low-to-mid-range screen, which can meet the user's needs and satisfy the user experience.
