Description

Technical Field

[0001] This invention relates to the field of computer hardware, and more specifically, to an ARGB full-color dynamic synchronous display system for graphics cards. Background Technology

[0002] With the rapid development of computer hardware technology, personal computers (PCs) are no longer limited to computing and office work, but have gradually become core tools in fields such as gaming, entertainment, and creative design. Especially in the gaming field, hardware appearance design and personalization have become part of what gamers pursue, and RGB lighting effects, as one of the important means to enhance the aesthetics of devices, have gained increasing popularity among consumers.

[0003] However, the limited range of lighting effects and the difficulty in synchronizing with other devices in the current RGB devices on the market restrict further improvements in user experience.

[0004] Therefore, we have made improvements to this and proposed an ARGB full-color dynamic synchronous display system for graphics cards. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that the lighting effects of RGB devices on the market are relatively simple.

[0006] To achieve the above-mentioned objectives, the present invention provides the following ARGB full-color dynamic synchronous display system for graphics cards to improve the aforementioned problems.

[0007] The application is as follows:

[0008] A graphics card ARGB full-color dynamic synchronization display system includes:

[0009] The music spectrum analysis module is used to analyze audio signals in real time and classify music styles;

[0010] The dynamic lighting control module is used to generate corresponding lighting effects based on the music style;

[0011] The AURASYNC synchronization enhancement module is used to coordinate the lighting effects of the graphics card with other ARGB devices.

[0012] The user interaction module provides automatic and manual light effect control methods;

[0013] The music spectrum analysis module includes:

[0014] The music style classification unit is used to classify music styles as mellow, rock, or horror music based on the low-frequency / high-frequency energy ratio (E_low / E_high) and the standard deviation of high-frequency energy in adjacent frames (σ_high).

[0015] As a preferred technical solution of this application, the music spectrum analysis module further includes:

[0016] An audio input unit is used to acquire audio signals and perform noise reduction and normalization processing;

[0017] The FFT spectrum analysis unit is used to convert time-domain audio into frequency-domain energy distribution and divide it into low-frequency, mid-frequency, and high-frequency energy bands.

[0018] As a preferred technical solution of this application, the classification rule of the music style classification unit is as follows:

[0019] Smooth music: E_low / E_high > 3 and σ_high < threshold 1;

[0020] Rock music: E_high / E_low > 1.5 and σ_high > threshold 2;

[0021] Horror music: E_low / E_high>2 and occasional high-frequency spikes exist (peak value>3 times the average value).

[0022] As a preferred technical solution of this application, the dynamic light effect control module includes:

[0023] The lighting effects strategy unit is used to match preset lighting effect templates according to music style, including:

[0024] Soothing music corresponds to cool tones (blue / purple), low to medium brightness, and gradient effects;

[0025] Rock music corresponds to warm colors (red / orange), high brightness, and rapid flashing effects;

[0026] Horror music corresponds to dark green / deep red tones, low brightness, and random flickering effects;

[0027] The lighting driver unit is used to convert HSV parameters into RGB signals and drive LED beads through PWM dimming.

[0028] As a preferred technical solution of this application, the lighting driving unit supports LED group control, dividing the graphics card LEDs into fan area and backplate area, and realizing zoned differentiated lighting effects in horror mode.

[0029] As a preferred technical solution of this application, the AURASYNC synchronization enhancement module includes:

[0030] Device identification unit, used to detect and identify ARGB devices and supported protocols in the system;

[0031] The synchronization algorithm unit is used to select master or slave mode and ensure the synchronization of light effects of multiple devices through time offset compensation.

[0032] As a preferred technical solution of this application, the synchronization algorithm unit supports dynamic master-slave switching. When the motherboard is detected to have enabled lighting effect control, the graphics card automatically switches to slave mode.

[0033] As a preferred technical solution of this application, the user interaction module includes:

[0034] The control software unit provides a graphical interface for configuring hue, brightness, and dynamic effects, and supports keyframe programming.

[0035] The hardware control unit allows for mode switching, brightness adjustment, and effect switching via physical buttons and knobs.

[0036] As a preferred technical solution of this application, the music spectrum analysis module, dynamic light effect control module, AURASYNC synchronization enhancement module and user interaction module work in coordination through priority logic. Among them, the manual setting of parameters has higher priority than the automatic music response, and a gradual transition algorithm is used to avoid visual abruptness when switching light effects.

[0037] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0038] In the scheme of this application:

[0039] 1. Through the dynamic lighting effect control module, adaptive lighting effect mapping (cool / warm / horror tone) based on music style is realized. It can not only automatically match the best lighting effect scheme according to the music type, but also synchronize the light intensity with the music energy change through real-time fine adjustment mechanism, which enhances the immersive visual-auditory experience and solves the problem that the lighting effects of RGB devices on the market are relatively simple in the existing technology.

[0040] 2. Through the music spectrum analysis module, real-time spectrum analysis of audio signals and intelligent classification of music styles are realized. It can accurately distinguish three typical styles: soothing music, rock music and horror music. The dynamic weight adjustment mechanism avoids misjudgment and makes the lighting effects match the emotional expression of the music, improving flexibility and solving the problem that the lighting effects of RGB devices are disconnected from the audio content and can only simply follow the rhythm changes in the existing technology.

[0041] 3. By setting up an FFT spectrum analysis unit, dynamic weight adjustment of low-frequency / high-frequency energy is realized. Frame processing and Hanning window technology are used to improve the accuracy of spectrum analysis. At the same time, the time domain rate of change detection is used to distinguish between continuous music features and instantaneous noise, thereby improving the classification accuracy. This solves the problem of music style misjudgment caused by fixed thresholds in the existing technology (such as misidentifying drum beats as horror sound effects).

[0042] 4. By setting up the AURASYNC synchronization enhancement module, intelligent master-slave switching of cross-brand ARGB devices is realized, and a complete synchronization solution including device identification, protocol conversion and command distribution is established, enabling devices from different manufacturers to work harmoniously and solving the problem of multi-device lighting effect conflicts (such as motherboard and graphics card competing for control) in existing technologies.

[0051] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0052] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0053] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0054] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0055] Example 1

[0056] Please refer to Figure 1 and Figure 2 A graphics card ARGB full-color dynamic synchronization display system, comprising:

[0057] The music spectrum analysis module analyzes audio signals in real time, extracts key frequency features, and classifies music styles to drive dynamic lighting effects.

[0058] The dynamic lighting effect control module transforms music style classification results into specific lighting effects, and ensures that the changes in lighting effects are natural and intuitive for users.

[0059] The AURASYNC synchronization enhancement module's core task is to coordinate the synchronization between the graphics card's lighting and other ARGB devices in the system (motherboard, memory, fans, etc.) to ensure uniform lighting effects while retaining the graphics card's flexibility as the main control device.

[0060] The user interaction module provides users with flexible light effect control, allowing seamless switching between automatic music response and manual settings, while ensuring intuitive operation.

[0061] Furthermore, such as Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, the music spectrum analysis module includes:

[0062] The audio input unit acquires and preprocesses audio signals, prioritizing direct capture of audio streams from the system sound card (e.g., output from game / music players). If system audio permissions are unavailable, ambient sound is collected via an external microphone (requiring noise reduction). Noise reduction includes high-pass filtering (cutoff frequency 20Hz) to remove DC offset and low-frequency noise; normalization uses dynamic range compression to prevent sudden volume changes from affecting analysis; and ensures automatic switching to default lighting effects when there is no music input (e.g., in mute mode) to avoid unresponsiveness.

[0063] The FFT spectrum analysis unit converts time-domain audio into frequency-domain energy distribution, segmenting the audio into 50ms frames (balancing real-time performance and frequency resolution), and using a Hann window to reduce spectral leakage. A 256-point FFT is performed on each frame to output the frequency-domain energy spectrum, with frequency bands divided as follows: low frequency (20-250Hz): bass / drum energy; mid frequency (250-2kHz): vocals / melody; high frequency (2kHz-20kHz): cymbals / sharp effects. In rock music, high frequencies are prominent, but if there is a sudden increase in low-frequency energy (such as drum beats), the low-frequency weight is temporarily increased to avoid misinterpreting it as horror music.

[0064] Music style classification unit, classifying music styles based on spectral characteristics, low-frequency / high-frequency energy ratio (E_low / E_high), standard deviation of high-frequency energy between adjacent frames (σ_high), classification rules:

[0065] Smooth music, condition: E_low / E_high>3 and σ_high<threshold 1, example: classical music, ambient sound effects;

[0066] Rock / radical music, condition: E_high / E_low>1.5 and σ_high>threshold 2, example: electronic music, metal music;

[0067] Horror music, conditions: E_low / E_high>2 and σ_high has occasional spikes (e.g., peak value > 3 times the average value), examples: horror movie soundtrack, sudden screams; if the high-frequency spikes are short in duration (<100ms), they are considered transient noise (e.g., the sound of breaking glass) and do not trigger the horror mode;

[0068] When switching styles, the lighting effects should gradually transition (e.g., from rock to horror, the color tone should change from red to dark green within 2 seconds) to avoid abrupt changes.

[0069] Furthermore, such as Figure 1 , Figure 2 , Figure 4 , Figure 7 and Figure 8 As shown, the dynamic lighting effect control module includes:

[0070] The lighting effect strategy unit matches preset lighting effect templates based on music style and dynamically adjusts parameters. Input: Receives the classification results (smooth / rock / horror) from the music spectrum analysis module; Strategy matching:

[0071] Soothing music: Hue: Cool (blue / purple, Hue value 200°-280°); Brightness: Low-medium (30%-60% brightness); Variation mode: Gradient (like a slow sine wave, period 2-4 seconds);

[0072] Rock music: Hue: Warm (red / orange, Hue value 0°-60°); Brightness: High (80%-100% brightness); Variation mode: Rapid flashing (e.g., square wave, frequency 5-10Hz);

[0073] Horror music: Hue: dark green (Hue value 100°-120°) or deep red (Hue value 0°-10°); Brightness: low (10%-30% brightness); Variation mode: random strobe (sudden on and off, interval 0.1-0.5 seconds);

[0074] Fine-tune the lighting effects based on real-time audio characteristics (e.g., the stronger the high-frequency energy in rock music, the higher the red saturation); cool colors (blue / purple) create a sense of calm, warm colors (red / orange) enhance excitement, and dark green triggers tension.

[0075] The lighting driver unit converts the lighting effect strategy into hardware control signals to drive the LED beads. Signal conversion involves converting hue, saturation, and brightness into RGB values ​​(HSV→RGB conversion algorithm). Example formula:

[0076] R = V * (1 - S + S * cos(Hue))

[0077] G = V * (1 - S + S * cos(Hue - 120°))

[0078] B = V * (1 - S + S * cos(Hue + 120°))

[0079] PWM dimming: Adjusts LED brightness by duty cycle (e.g., brightness 50% = PWM duty cycle 50%); LED group control: Divides the graphics card LEDs into multiple logic zones (e.g., fan zone, backplate zone), supporting independent control; In horror mode, the backplate zone remains dark green, and the fan zone randomly flashes to simulate a "ghosting" effect; Uses a hardware PWM generator (e.g., PCA9685) instead of software PWM to avoid MCU performance bottlenecks.

[0080] Example 2

[0081] The ARGB full-color dynamic synchronous display system for graphics cards provided in Example 1 has been further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 5 and Figure 7 As shown, the AURASYNC synchronization enhancement module includes:

[0082] The device identification unit automatically detects ARGB devices in the system and establishes communication links, enumerating connected devices via the motherboard's USB or 5VA RGB interfaces; identifying device types (such as motherboard, memory, fans) and supported protocols (such as ASUS Aura, MSIMystic Light); if the device supports an open protocol (such as Adalight), a control channel is directly established; if the device only supports a manufacturer's proprietary protocol (such as ASUS Aura), instructions are converted through reverse engineering or middleware; then a device connection diagram is generated, marking the master control node (usually the graphics card or motherboard); when the motherboard does not support AURASYNC, the graphics card triggers motherboard lighting effect synchronization via USB HID to simulate keyboard signals (a preset mapping table is required);

[0083] The synchronization algorithm unit selects the optimal synchronization strategy based on the system configuration and handles instruction distribution. First, it selects the mode: master mode (default): the graphics card acts as the master of lighting effects and broadcasts RGB instructions to other devices (such as "set all devices to red"); slave mode: the graphics card synchronizes with the motherboard lighting effects (if Aura Sync is detected to be enabled on the motherboard, it will automatically switch to the slave role).

[0084] Command distribution: In master mode, the graphics card broadcasts lighting effect frames every 50ms, including: device ID (to distinguish the target), RGB value (or HSV value), and change mode (such as gradient, flashing); a time offset is added to distant devices (such as case fans) (e.g., latency = cable length × 5ns / m) to ensure lighting effect synchronization; if the motherboard suddenly enables lighting effect control, the graphics card automatically degrades to a slave device to avoid "lighting effect contention"; when multiple master devices send commands at the same time, the command from the last device to be received is given priority (arbitrated by timestamp).

[0085] The AURASYNC synchronization enhancement module is only responsible for command distribution and does not participate in music classification, but it receives RGB commands generated by the light effect strategy module. After the light effect strategy module outputs HSV parameters, the synchronization module converts them into a device-compatible protocol format (such as ASUS Aura's hexadecimal code). When the user manually switches between master / slave modes, the synchronization module updates the topology configuration and reconnects to the device.

[0086] Furthermore, such as Figure 1 , Figure 2 , Figure 6 and Figure 8 As shown, the user interaction module includes:

[0087] The control software unit provides a graphical interface, allowing users to deeply customize lighting effects; mode selection:

[0088] Automatic mode: Enables the music spectrum analysis module, and the light effects are driven by the music style; Manual mode: Users can directly set the color, brightness, and dynamic effects (such as breathing and rainbow);

[0089] Parameter configuration: Hue: 0°-360° color wheel selection; Value: 0%-100% slider control; Dynamic effects: preset modes (such as gradient, flash, sound wave) or custom timing (programmable keyframes);

[0090] It supports saving lighting effect schemes as configuration files and switching between different scene schemes (such as "game mode" and "movie mode") with one click; users can define time-color curves (such as 0s red → 2s blue → 5s purple) to achieve complex lighting effects; when manually adjusting a parameter (such as brightness), only that parameter is overridden, and the rest are still controlled by the music analysis module.

[0091] Hardware control unit, allowing quick switching of frequently used functions via physical buttons / knobs; Hardware structure: Graphics card PCB integrates 3 buttons: Mode switching: cycles through automatic / manual / preset modes; Brightness adjustment: short press to increase or decrease brightness, long press to reset; Effect switching: short press to switch preset dynamic effects; 1 RGB status indicator: blue: automatic mode / green: manual mode / red: error status;

[0092] Signal processing: Button debounce (50ms delay for judgment) to avoid accidental touches; knob encoder directly maps to brightness value (0%-100% linear correspondence); differentiated button tactile feel (mode button raised, brightness button recessed) to eliminate the need for visual assistance; rapidly flashing indicator light indicates "mode switching", while constant light indicates "stable operation".

[0093] In automatic mode, the user interaction module disables some manual parameters (such as color), but allows fine-tuning of brightness / speed; the manual parameters set by the user directly override the output of the light effect strategy unit (priority: manual > automatic); when the user switches modes, the synchronization module broadcasts instructions to other devices to ensure overall consistency.

[0094] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0095] Obviously, the embodiments described above are merely some embodiments of the present invention, not all embodiments. The accompanying drawings show preferred embodiments of the present invention, but do not limit the patent scope of the present invention. The present invention can be implemented in many different forms; rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of the present invention.
