[0037] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] In traditional all-in-one PCs, the connection between the display unit and the motherboard uses a conventional wire cable solution, such as Teflon or coaxial cable, which is expensive. Furthermore, the display signals and power supply voltages used in the connection usually vary depending on the display unit, such as LVDS (Low Voltage Differential Signaling), eDP (Embedded DisplayPort), V-by-one (Video by One), or different power supply voltage levels. This connection method does not allow for quick and convenient replacement of the display unit.

[0039] Based on this, embodiments of this application provide an electronic device for overcoming at least some of the drawbacks of the traditional connection method between the display unit and the motherboard of electronic devices such as detachable all-in-one machines.

[0040] See Figure 1 The illustrated electronic device composition diagram shows that, in an optional embodiment, the electronic device provided in this application includes a first body 10 and a second body 20.

[0041] The first body is used to generate display information and output the display information through a first signal.

[0042] The first component can be the host or motherboard (MB) of an electronic device. Taking an all-in-one device as an example, the first component can be the motherboard of the all-in-one device. See [link to relevant documentation]. Figure 2 For example, the motherboard of the all-in-one PC can be set in the host compartment on the back of the monitor, and the host compartment can be directly fixed to the metal bracket or shell behind the screen.

[0043] The first device may be equipped with a graphics card, such as a dedicated graphics card or an integrated graphics card, and can generate the display information through the graphics card. The generated display information may include, but is not limited to, various types of display information such as text, images, and videos, depending on the actual application requirements.

[0044] In addition, optionally, the first body may also be equipped with various components such as a central processing unit, memory, storage, I / O (Input-Output), and PSU (Power Supply Unit) (e.g., by plugging or soldering) to provide various functions such as information processing, system control, data storage, input / output and / or power supply required by the electronic device.

[0045] The first signal may include, but is not limited to, the first display signal and / or the first power signal.

[0046] The first display signal can be a display signal output by the graphics card, used to carry display information such as text, images / videos generated by the graphics card. The first power signal can be a power signal output by a power supply unit such as the PSU in the first unit, used to drive the display unit to display information from the power supply side.

[0047] The second body is the body where the display unit of the electronic device is located, see [link / reference]. Figure 2 For example, the main body represented by the display of an all-in-one machine may include, but is not limited to, the display unit 201 and the signal conversion unit 202.

[0048] The display unit is used for information display and can be the display screen of an electronic device or a core component of the display screen used for information display, such as the LCD screen of an all-in-one machine or a core component of the display screen used for information display.

[0049] The signal conversion unit is used to receive the first signal output by the first body and convert the first signal into a second signal required by the display unit to display information, so that the display unit can display information based on the second signal.

[0050] Optionally, the signal conversion unit may include a first conversion unit and / or a second conversion unit.

[0051] The first conversion unit is responsible for providing the format conversion function of the display signal. It can be, but is not limited to, a display conversion chip Scaler of the electronic device, used to convert the first display signal into a second display signal in a format required by the display unit. For example, it can convert the first display signal output by the motherboard into a second display signal in a specific format such as LVDS, eDP, V-by-one required by the display unit, so that the display unit can display information based on the second display signal.

[0052] The second conversion unit is responsible for providing voltage conversion function, and may be, but is not limited to, a backlight conversion chip of an electronic device, for converting the first power signal with the first voltage value output by the first body into a second power signal with the second voltage value required by the backlight of the display unit, so as to drive the display unit to display information based on the second power signal.

[0053] See Figure 3 A comparative diagram of the architecture of the electronic device in this application and the conventional technology is provided, wherein "Before" represents the architecture of the electronic device in the conventional technology, and "Now" represents the architecture of the electronic device in this application. In the conventional technology, the signal conversion units such as the display conversion chip and backlight conversion chip of the electronic device (such as an all-in-one machine) are located on the motherboard MB, which results in the display signals (such as...) connected between the motherboard and the display unit being... Figure 3The different display signals (LVDS or eDP) and power supply voltages connected between the motherboard MB and the display unit Panel need to be different depending on the display unit, making it impossible to replace the display unit more quickly and conveniently.

[0054] See Figure 3 As shown, in this embodiment, signal conversion units such as the display conversion chip Scaler and the backlight conversion chip BL (Backlight) board are separated from the first body such as the motherboard and disposed in the display unit such as... Figure 3 The second body, where the Panel is located, can support unified or standardized design of display signals and power signals at the connection between the first and second bodies. For example, Figure 3 In this process, the display signal at the connection point between the first body (represented by MB) and the second body (where the Panel is located), i.e., the first display signal, is unified into an eDP. Subsequently, according to the different display signal requirements of the Panel, the unified display signal can be converted into the required second display signal at the second body end by a first conversion unit such as a display conversion chip (Scaler). Similarly, the power signal at the connection point between the first body and the second body, i.e., the first power signal, can be designed to have a unified voltage, such as 20V. Subsequently, according to the different voltage requirements of the backlight of the display unit for the power signal, the unified power signal can be converted into the required second power signal at the second body end by a second conversion unit such as a backlight conversion chip. Thus, the display signal and power voltage connected between the motherboard and the display unit will not differ depending on the display unit.

[0055] In summary, by separating the signal conversion unit from the first body and placing it in the second body where the display unit is located, this application can support the unified or standardized design of the display signal and power signal at the connection between the first body and the second body, thereby being compatible with display units of different models / sizes / resolutions and supporting quick and convenient replacement of the display unit.

[0056] In one alternative embodiment, the electronic device may further include a light-emitting unit, a first connecting line, and a second connecting line.

[0057] The light-emitting unit, the first connecting line, and the second connecting line are all located on the second body of the electronic device, namely the body where the display unit is located.

[0058] Optionally, the light-emitting unit can be a backlight for the display unit, providing backlight illumination for the information display. Specifically, the light-emitting unit can be lit based on a second power signal output by a second conversion unit, such as a backlight conversion chip, to illuminate the display unit.

[0059] The first connecting line is used to connect the first conversion unit and the display unit. For example, the display conversion chip Scaler and the display unit panel are connected through the first connecting line to transmit the second display signal output by the first conversion unit to the display unit, so that the display unit displays information based on the second display signal.

[0060] The second connecting line is used to connect the second conversion unit and the light-emitting unit. For example, the backlight conversion chip and the backlight source are connected through the second connecting line to transmit the second power signal output by the second conversion unit to the light-emitting unit, so that the light-emitting unit can be lit up, thereby supporting the display unit to light up the screen and display information.

[0061] Among them, the first connecting line and the second connecting line are first-class connecting lines. The signal transmission rate of the first-class connecting lines reaches a first threshold, and the signal attenuation rate reaches a second threshold.

[0062] Category 1 cables can be, but are not limited to, standard FFC (Flexible Flat Cable).

[0063] Traditional wire cables (such as Teflon or coaxial cables) have the characteristics of high signal transmission rate and low signal attenuation rate, which leads to higher cost of traditional wire cables.

[0064] This embodiment uses a first type of connecting cable that satisfies the aforementioned signal transmission rate and signal attenuation characteristics for both the first and second connecting cables. This ensures that the signal transmission rate is not sacrificed compared to traditional wire cables, while reducing cable costs by increasing the signal attenuation rate. Since this embodiment separates the signal conversion units, such as the display conversion chip and backlight conversion chip, from the first body and places them in the second body where the display unit is located, the lengths of the first and second connecting cables are shortened. This allows both to use connecting cable types with higher attenuation, such as FFC. Furthermore, because this embodiment shortens the lengths of the first and second connecting cables, the signal attenuation of the first and second connecting cables does not increase or significantly increase compared to traditional technologies when using connecting cable types with higher attenuation, such as FFC. This ensures both the signal transmission rate of the first and second connecting cables and avoids an increase or significant increase in signal attenuation, while simultaneously reducing cable costs.

[0065] In an alternative embodiment, the electronic device may further include a connection unit for connecting the first body and the second body.

[0066] The connection unit includes a first sub-connection unit disposed on a first body and a second sub-connection unit disposed on a second body. The first sub-connection unit is used to connect to the second sub-connection unit, and the connection between the first body and the second body is realized by connecting the first sub-connection unit to the second sub-connection unit.

[0067] The first sub-connecting unit and the second sub-connecting unit can each be a connector capable of interconnecting with each other. See also Figure 4 For example, the first sub-connection unit may be, but is not limited to, a connector in the form of a gold finger, and the second sub-connection unit may be, but is not limited to, a PCIE (Peripheral Component Interconnect Express, high-speed serial computer expansion bus standard) type connector, such as a PCIE4 connector.

[0068] Designing the first sub-connection unit as a gold-finger connector provides, but is not limited to, modular design, precise mechanical positioning and foolproof design, and adaptability to high power and high density requirements. Designing the second sub-connection unit as a PCIe connector provides, but is not limited to, hot-swapping and power management, low-latency and high-efficiency communication, high reliability and signal integrity, and flexible expandability and configurability. This design allows for convenient plug-and-play connection between different components of this application, while also supporting efficient communication and power management between them.

[0069] Optionally, a switch unit may also be provided on the first sub-connection unit, which is used to lock or unlock the interconnected first and second sub-connection units.

[0070] The switch unit can be a double-latch structure with a self-locking function after pulling both latches. This facilitates the user's tactile feedback when connecting the first and second bodies and also serves as a foolproof mechanism to prevent the second body (the body containing the display unit) from accidentally detaching from the first body. However, it is not limited to this; the switch unit can also be, but is not limited to, a cam-locking pin structure, a push-button lock mechanism, or a hook-spring lock mechanism, etc.

[0071] Alternatively, the connection end of the first sub-connecting unit and the second sub-connecting unit can also be configured as a target shape or target structure, which is used to facilitate the alignment between the first sub-connecting unit and the second sub-connecting unit.

[0072] The target shape can be, but is not limited to, a chamfered shape. For example, adding a chamfered design to the connection end between the PCIe4 connector and the gold fingers makes the connection point between the PCIe4 connector and the gold fingers chamfered, making it easier for the gold fingers to enter the travel range when inserted into the PCIe4 connector. The target structure can include, but is not limited to, adding physical guide posts on both sides of the connection unit interface, forcing the user to align one connection unit with another (such as inserting one connector into another, similar to the foolproof design of the Type-A interface), or the target structure can be designed as a floating margin of the connection unit interface itself, so that even if there is a slight misalignment during insertion, it can be automatically corrected.

[0073] The structure of the connection unit in this embodiment is stronger than that of traditional pogo pins and USB (Universal Serial Bus) C, which can avoid the crash problem of the second body when connecting the first body and the second body. This embodiment provides a switch unit with a double latch structure on the first connection sub-unit, which can facilitate the locking or unlocking of the first sub-connection unit and the second sub-connection unit, and can play a foolproof role to prevent the second body (the body where the display unit is located) from falling off the first body due to user misoperation. In addition, by designing the connection end of the first sub-connection unit and the second sub-connection unit as a target shape or target structure, this embodiment can promote the alignment between the first sub-connection unit and the second sub-connection unit, making it easier to enter the stroke when connecting different connection units, such as inserting one connector into another connector.

[0074] In an optional embodiment, the electronic device provided in this application may further include a third connection line and a fourth connection line for connecting the first body and the first sub-connection unit in the connection unit, such as a third connection line and a fourth connection line for connecting the motherboard and the PCIE4 connector.

[0075] The third connecting line is used to transmit the first display signal.

[0076] The fourth connection line is used to transmit the first power signal.

[0077] Optionally, the third connecting line is a second type of connecting line, and the fourth connecting line is a first type of connecting line; the signal transmission rate of the second type of connecting line reaches the third threshold, the signal attenuation rate reaches the fourth threshold, but does not reach the second threshold; the third threshold is higher than the first threshold, and the fourth threshold is lower than the second threshold.

[0078] In other words, the signal transmission rate of Category 2 cables is higher than that of Category 1 cables, and the signal attenuation rate of Category 2 cables is lower than that of Category 1 cables. Optionally, the signal attenuation rate of Category 2 cables is higher than that of traditional wire cables (such as Teflon or coaxial cables).

[0079] Category 2 connectors can be, but are not limited to, high-speed FFC. Optionally, high-speed FFC can be formed by combining ordinary FFC with a high-speed sheath and high-speed shielding material. High-speed FFC has a higher signal transmission rate and a lower signal attenuation rate than ordinary FFC. Furthermore, the signal attenuation rate of high-speed FFC falls between that of ordinary FFC and traditional wire cable, and its cost is also between that of ordinary FFC and traditional wire cable. Compared to traditional wire cable, the cost of high-speed FFC can be reduced by more than 50%.

[0080] See Figure 5 This example illustrates the internal connections between different units in an all-in-one PC. In this example, the first connection line between the display conversion chip (Scaler) and the display unit (represented as LVDS in the diagram) within the second unit, the second connection line between the backlight conversion chip and the backlight source (BL), and the fourth connection line between the first unit and the first connection subunit (such as a PCIe 4 connector) for transmitting the first power signal all utilize standard FFC (Flexible Connection Cable). Figure 5 The FFC cable in the first body and the third connection line between the first body and the first connection subunit for transmitting the first display signal uses a high-speed FFC, such as... Figure 5 High Speed ​​FFCcable.

[0081] In addition, other connecting cables in the two main bodies of the electronic device can also be selected as either Type I or Type II connecting cables, such as... Figure 5 The camera connector on the second body is connected to the camera (Cam) using a standard FFC.

[0082] Electronic devices typically have high requirements for the transmission rate of display signals. In this embodiment, by using a high-speed FFC or other type II connection cable for the third connection line used to connect the first body and the first sub-connection unit and transmit the display signal, the transmission rate of the display signal is further improved, which can better meet the transmission rate requirements of electronic devices for display signals. At the same time, compared with traditional wire cables, the cost of the connection cable is reduced.

[0083] In an alternative embodiment, the width of the terminal pin of at least one of the second and fourth connecting lines reaches a fifth threshold and / or the thickness reaches a sixth threshold.

[0084] In this embodiment, the width of the terminal pin of at least one of the second and fourth connecting lines is designed to reach a fifth threshold, which is used to increase the width of the terminal pin of at least one of the second and fourth connecting lines, so as to reduce the power loss on the second and / or fourth connecting lines by increasing the width of the terminal pin.

[0085] Wherein, the width of the terminal pin of at least one of the second connecting line and the fourth connecting line reaches the fifth threshold, which may, but is not limited to, mean that the terminal pins inside the second connecting line and / or the fourth connecting line that meet the proximity condition are merged into one, and the pin width of the integrated pin formed after merging into one reaches the fifth threshold.

[0086] Optionally, the proximity condition can be set as follows: two terminal pins inside the connection line are adjacent, or two or more terminal pins are sequentially adjacent.

[0087] See Figure 6 For example, this example increases the width of at least some of the terminal pins in the second / fourth connection line by merging at least a portion of sequentially adjacent terminal pins in a common FFC or other second connection line into one, thereby reducing the power loss of the second and / or fourth connection line.

[0088] In this embodiment, the thickness of the terminal pins of at least one of the second and fourth connecting lines is designed to reach a sixth threshold, which is used to increase the thickness of the terminal pins of at least one of the second and fourth connecting lines. For example, see [link to example]. Figure 6 For example, the thickness of the ordinary FFC used in the second and fourth connecting lines can be increased from the traditional 0.035mm to 0.05mm, so as to reduce the power loss on the second and / or fourth connecting lines by increasing the thickness of the terminal pins.

[0089] exist Figure 6 In the example, after at least a portion of the sequentially adjacent terminal pins within a standard FFC (second connection line / fourth connection line) are merged into one piece, and the thickness of the standard FFC is increased from the traditional 0.035mm to 0.05mm, as... Figure 6 As shown, it can effectively reduce pin resistance and increase current (e.g., increase the original 0.5A current to 1.5A), thereby reducing line loss. At the same time, it can increase the current range supported by FFC, for example, by about 50%, to support a larger current flow.

[0090] This embodiment can effectively reduce power loss on the second and / or fourth connecting lines by increasing the thickness and / or width of the terminal pins of at least one of the second and fourth connecting lines, thereby reducing line loss, improving the power consumption utilization of the device, and saving electricity costs.

[0091] In an optional embodiment, the electronic device provided in this application may further include a third body for supporting the first body.

[0092] In all-in-one PCs, the main unit, such as the motherboard, is typically located in the main unit compartment at the back of the monitor. Unlike the separate structure of traditional desktop PCs, the main unit compartment is directly fixed to the metal bracket or casing behind the screen. Regarding this structure, such as... Figure 7 As shown, the third body can be a base for supporting the metal bracket or shell behind the screen of an electronic device. The base or other third bodies can be designed with corresponding connection structures, such as slots, to connect the base to the metal bracket or shell behind the screen of the electronic device and provide support for the metal bracket or shell, thereby supporting each body of the electronic device and making it convenient for users to use.
