With the progress of display technology, users have higher requirements for the picture quality, color performance, and visual experience of screens. The backlight technology emerged to enhance the viewing effect of screen content through the adjustment of ambient lighting and improve the user's visual experience. The backlight technology arranges LED strips or other light sources around or behind the screen and adjusts the light color and brightness according to the changes in the screen content to simulate the ambient light effect of the screen content.

[0076] Feedback display unit: Provides the system status information and feedback to the user, including through screen display or sound prompt.

[0077] System installation and connection:

[0078] Installation of HDMI video signal acquisition module:

[0079] Connect the input interface unit of the HDMI video signal acquisition module to the HDMI interface of an external device (such as a computer, game console, Blu - ray player), ensuring that the video signal can be stably transmitted to the acquisition module. During the connection process, pay attention to the correct plugging and unplugging of the interface to avoid damaging the interface;

[0080] The signal synchronization unit will automatically synchronize the received video signal with the timestamp of the input device to ensure the accuracy of the signal in subsequent processing;

[0081] The signal buffer unit starts to work, temporarily stores the received video signal, provides a stable data source for the signal processing and lamp control signal conversion module, and ensures that it can process continuously without interruption. When playing high-definition videos, there may be short-term data transmission peaks, and the signal buffer unit can effectively avoid processing interruptions caused by unstable data transmission;

[0082] Overall system connection

[0083] The HDMI video signal acquisition module and the signal processing and lamp control signal conversion module are connected through a suitable data transmission line (such as a high-speed data line) to ensure that the acquired HDMI video signal can be transmitted to the signal processing module in a timely and accurate manner;

[0084] A stable communication connection is established between the signal processing and lamp control signal conversion module and the wireless transmission module, and the generated lamp control signal is transmitted to the wireless transmission module for encoding and sending;

[0085] The wireless transmission module establishes a reliable wireless connection between the host and the slave devices distributed in each lamp. When installing the slave device, ensure that it is within the wireless signal coverage area and avoid interference from other wireless devices. The lamp control module in the slave device receives the lamp control signal through the wireless communication unit.

[0086] The user interaction module is connected to the signal processing and lamp control signal conversion module to realize information interaction between the user and the system. The power management module is connected to each of the other modules respectively. After converting the external power supply into the voltage and current required by the system, it reasonably distributes them to each module and monitors the power status in real time to ensure the stable operation of the system.

[0087] System operation process:

[0088] Signal acquisition and processing:

[0089] When an external device plays a video, the HDMI video signal acquisition module receives the HDMI video signal. After the input interface unit obtains the video signal, the signal synchronization unit ensures that the signal is synchronized with the input device timestamp, and the signal buffer unit stores the signal;

[0090] The HDMI signal parsing unit in the signal processing and lamp control signal conversion module decodes the HDMI signal, accurately extracts the color information, brightness, and contrast image data of the pixels, and then the image processing unit optimizes these data, removes noise interference through data filtering, performs color correction to improve color accuracy. Finally, the lamp control signal generation unit converts and generates a lamp control signal for controlling the lamp according to the processed image data. When there are a large number of red elements in the picture, a corresponding lamp control signal is generated to make the lamp emit red or warm-colored light;

[0091] Wireless Signal Transmission and Lamp Control:

[0092] The signal encoding unit of the wireless transmission module encodes the lamp control signal, and then the wireless communication unit sends the encoded signal through modulation and amplification operations. After the wireless communication unit of the slave device receives the signal, the signal decoding unit decodes it, extracts the lamp control signal and transmits it to the lamp control module;

[0093] After the signal receiving unit of the lamp control module receives the lamp control signal, the light adjustment unit adjusts the brightness, color and blinking frequency of the lamp according to the signal. If the lamp control signal requires reducing the brightness, the light adjustment unit will correspondingly reduce the power supply current of the lamp or adjust the working state of the light-emitting element. At the same time, the status feedback unit will feedback the current status information of the lamp (such as the actual brightness value, color temperature) to the system, so that the system can make adjustments and optimizations according to the feedback information to ensure that the lighting effect always matches the screen content precisely;

[0094] User Interaction Operations:

[0095] The user inputs configuration instructions through the input unit (touch screen, remote control or mobile application), such as selecting different lighting modes (movie mode, game mode), and adjusting the specific parameters of the lighting brightness and color;

[0096] After the instruction processing unit receives the user input instruction, it parses and converts it into a command executable by the system, and transmits it to the signal processing and lamp control signal conversion module. If the user selects the movie mode, the instruction processing unit will notify the system to make adjustments according to the preset lighting parameters of the movie mode;

[0097] The feedback display unit will provide the user with system status information and feedback. For example, when the user adjusts the lighting brightness, the numerical change of the brightness adjustment will be displayed on the screen, or the user will be prompted by sound whether the operation is successful, so that the user can clearly understand the running status of the system and the result of their own operation.

[0098] It should be understood that the above specific embodiments of the present invention are only used for exemplary illustration or explanation of the principles of the present invention, and do not constitute a limitation to the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the protection scope of the present invention.
