External Display Lighting Control for Smart TV Content Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart TVs face challenges in providing personalized lighting effects that match the content being displayed, leading to inadequate visual experiences for users, as existing display technologies do not effectively integrate real-time lighting adjustments with the screen content.
Innovation Solution
A display control method that involves obtaining a target image from the TV, determining display regions with a mapping relationship to external light-emitting display units, and sending color display data to these units to dynamically change their colors based on the content, thereby enhancing the display effect and user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a TV uses a fixed backlight display mode, then the display structure is simple and hardware costs are low, but the lighting effect cannot match different content scenes leading to poor visual experience
Solution Approach 1:
The patent segments the display system into two independent parts: a traditional screen display assembly and an external controllable display assembly (lighting units). The lighting units are divided into multiple independent segments that can be controlled separately, allowing different lighting effects for different screen regions without complicating the entire display system.
Solution Approach 2:
The patent introduces an image processing unit as an intermediary that receives the original image, extracts color information, and generates control signals for the external display assembly. This mediator translates between the screen content and the lighting units, enabling adaptive lighting without direct complex integration between the screen and lighting systems.
2Adaptability or versatility
If a TV implements real-time lighting effects matching screen content, then visual experience and immersion are improved, but additional hardware and system complexity increase
Solution Approach 1:
The external display assembly uses universal lighting units that can display multiple colors and patterns. These lighting units serve both as decorative elements and as content-matching visual effects devices. The same lighting hardware can adapt to different scene types (movies, games, sports) without requiring specialized components for each function.
Solution Approach 2:
The patent copies color information from the screen display to the external lighting units. The image processing unit extracts color data from each region of the screen and reproduces these colors through the corresponding lighting units, creating a synchronized visual effect that mirrors the screen content without requiring complex original lighting design for each scene.
3Manufacturing precision
If the TV screen displays content without region-specific color control, then the display system is simple, but the lighting cannot be precisely matched to different display regions
Solution Approach 1:
The patent divides both the screen display area and the external lighting assembly into corresponding regions. Each lighting unit is mapped to a specific screen region, allowing independent color control for each region. This segmentation enables precise region-to-lighting correspondence without requiring complex continuous control systems.
Solution Approach 2:
The system implements a feedback loop where the image processing unit continuously monitors the screen content, extracts color information from each region, and adjusts the lighting units in real-time. This feedback mechanism ensures that the lighting always matches the current screen content while using a relatively simple control architecture based on standard image processing techniques.

AI summary
A display control method, for a terminal externally provided with a display assembly, includes: obtaining a target image including a current display frame of the terminal; determining a display region in the target image, in which the display region has a mapping relationship with a display unit included in the display assembly; determining color display data of the display region; and sending the color display data to the display assembly, to make the display unit corresponding to the display region display a color corresponding to the color display data.
