Description

Technical Field

[0001] This utility model relates to the field of computer equipment technology, specifically to a computer device and its display wake-up device. Background Technology

[0002] Currently, in the field of electronic technology, especially in motherboard hardware design, when a system enters sleep mode and is woken up by pressing the power button, the screen may not display anything or even the system may freeze. This phenomenon not only affects the user experience but also poses a challenge to the reliability and stability of the device.

[0003] While some conventional designs have attempted to address this issue, existing solutions often fail to completely eliminate leakage current, leaving the device at risk of display abnormalities after waking from sleep mode. Therefore, it is necessary to develop a new hardware circuit design to ensure the device can display correctly and smoothly enter system operation after waking from sleep mode, thereby improving the device's stability and reliability.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0005] The inventors discovered that when commonly used electronic devices enter sleep mode (S3 state) and are woken up by pressing the power button, the screen sometimes fails to display properly. This is because residual voltage from other chips on the motherboard causes leakage, leading to timing abnormalities. The monitor's signal and power supply are related to 3.3V, hence the lack of display. Specifically, to meet user needs, protocol conversion chips are often used in computer devices to expand their interfaces. When the S3 sleep mode malfunctions, the machine still retains a voltage above 0.6V. This is mainly due to leakage of the P5V_S3 signal from the USB control hub chip into the USB 2.0 P signal, which then flows back to the protocol conversion chip, and finally back to 3.3VS, causing abnormal leakage.

[0006] In view of this, the purpose of this utility model is to provide a computer device and its display wake-up device, which can effectively solve the display problem that occurs when existing electronic devices wake up from sleep mode.

[0007] This utility model provides a display wake-up device, which includes: a substrate, and a power supply port module, a magnetic bead assembly, and a conversion chip disposed on the substrate. The power supply of the computer device is used to electrically connect with the power supply port module and the display screen. The power supply port module is electrically connected to the power supply terminal of the conversion chip through the magnetic bead assembly. The data terminal of the conversion chip is used to electrically connect with an external module.

[0008] The power supply port module and the magnetic bead assembly are configured to provide a stable power supply to the conversion chip to avoid leakage when the machine is in sleep mode.

[0009] Preferably, the magnetic bead assembly includes a first magnetic bead disposed on the FB10 bit of the conversion chip and a second magnetic bead disposed on the FB13 bit of the conversion chip, wherein the first magnetic bead and the second magnetic bead are configured to supply power to the conversion chip after the computer device is powered on.

[0010] Preferably, the conversion chip is model UPD720201.

[0011] Preferably, it also includes a housing, with the substrate disposed inside the housing.

[0012] This utility model also provides a computer device, which includes a device body, a display screen, an external module, and a display wake-up device as described in any of the above, wherein the power supply of the device body is electrically connected to the power supply port module and the power supply terminal of the display screen, and the data terminal of the conversion chip is electrically connected to the external module.

[0013] Preferably, the external module includes a keyboard, mouse, solid-state drive, and high-definition video capture card.

[0014] Preferably, the device further includes an indicator light module, wherein the output terminal of the device body is electrically connected to the input terminal of the indicator light module.

[0015] Preferably, the device further includes a sound warning module, wherein the output terminal of the device body is electrically connected to the input terminal of the sound warning module.

[0016] In summary, the core improvement of the display wake-up device lies in changing the power supply method of the conversion chip to P3V3_STBY power supply and rearranging the position of the ferrite beads in the circuit. This ensures that the P3V3_STBY voltage remains stable during device sleep, effectively avoiding leakage problems. This design not only improves the stability and reliability of the device but also ensures that the device can quickly resume normal display and system operation after waking from sleep.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0022] Please see Figures 1 to 3 The first embodiment of this utility model discloses a display wake-up device, which includes: a substrate, and a power supply port module, a magnetic bead assembly and a conversion chip disposed on the substrate, wherein the power supply of the computer device is used to electrically connect with the power supply port module and the display screen, the power supply port module is electrically connected to the power supply terminal of the conversion chip through the magnetic bead assembly, and the data terminal of the conversion chip is used to electrically connect with an external module;

[0023] The power supply port module and the magnetic bead assembly are configured to provide a stable power supply to the conversion chip to avoid leakage when the machine is in sleep mode.

[0024] Preferably, the magnetic bead assembly includes a first magnetic bead disposed on the FB10 bit of the conversion chip and a second magnetic bead disposed on the FB13 bit of the conversion chip, wherein the first magnetic bead and the second magnetic bead are configured to supply power to the conversion chip after the computer device is powered on.

[0025] Specifically, in this embodiment, the display wake-up device is used to address display problems that may occur when a computer device wakes up from sleep mode. This device is ingeniously integrated onto a substrate and includes a power supply port module, a ferrite bead assembly, and a conversion chip, which together ensure the stability of the power supply and the reliability of data transmission. The power supply port module is the power interface of the device; it is directly electrically connected to the power supply of the computer device and is responsible for stably transmitting power to other parts of the device. The design of this module takes into account the stability of the power supply and the sufficiency of the current, ensuring that the power supply is not interrupted during the device's sleep and wake-up processes.

[0026] In this embodiment, the ferrite bead assembly is a key component connecting the power supply port module and the power supply terminal of the conversion chip. It includes a first ferrite bead configured on the FB10 bit of the conversion chip and a second ferrite bead configured on the FB13 bit. These two ferrite beads work together to supply power to the conversion chip after the computer device is powered on. Their configuration helps filter high-frequency noise on the power line and provides a stable power path, avoiding device wake-up failures or display problems caused by power fluctuations. This layout and configuration of the ferrite beads is crucial for ensuring power stability and helps reduce electromagnetic interference, improving the reliability of the entire system. The data terminal of the conversion chip is used for electrical connection with external modules to achieve high-speed data transmission. The power supply terminal of the conversion chip is electrically connected to the power supply port module through the ferrite bead assembly, ensuring a stable power supply when the device is in sleep mode, thereby avoiding leakage. This design not only improves the stability and reliability of the device but also ensures that the device can quickly resume normal display and system operation after waking from sleep mode.

[0027] In this embodiment, in the traditional solution, the magnetic bead is placed on FB1 and FB12. The original magnetic bead is powered by AC power, meaning it will be energized when connected to AC power. However, after the magnetic bead is repositioned, it is powered by P3V3_STBY (i.e., the power supply port module). This means it will only be energized when the motherboard is powered on. After the device is powered off, it will not be energized even when AC power is connected, and there is no possibility of leakage.

[0028] Preferably, the conversion chip is model UPD720201.

[0029] It should be noted that other types of conversion chips may be used in other embodiments, which are not specifically limited here, but these solutions are all within the protection scope of this utility model.

The housing design fully considers dustproofing, moisture resistance, and impact resistance, protecting the internal components from external environmental influences while also facilitating the installation and maintenance of the entire device.

[0032] In summary, the aforementioned display wake-up device significantly improves power supply stability through optimized design of the power supply port module and ferrite bead assembly. This design not only reduces energy consumption in sleep mode but also ensures the device can quickly resume normal operation upon wake-up, enhancing the user experience. Furthermore, a stable power supply helps extend the device's lifespan and reduces device failure rates caused by power issues.

[0033] In short, this invention provides an effective display wake-up device through a carefully designed power supply port module, ferrite bead assembly, and conversion chip, solving the problem of computer devices failing to display after waking from sleep mode. It possesses significant technical advantages and market application value. This design not only improves the device's response speed and reliability but also provides users with a smoother and more worry-free user experience.

This visual prompt provides users with an intuitive way to identify and respond to system status, enhancing the user experience.

[0040] Furthermore, LED indicator lights are an ideal choice due to their low power consumption, fast response, and long lifespan. In this embodiment, LED indicator lights are used not only to indicate system status but also to warn users of potential abnormalities, such as data transmission errors, system overload, or hardware failure.
