Backlighting System with Position-Dependent Response Times
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current visual display systems struggle to simultaneously provide both relaxed and immersive viewing experiences due to conflicting requirements for backlighting response times, leading to restless or inadequate peripheral viewing effects.
Innovation Solution
A system that uses varying reaction times for different illumination areas based on their position within the display system, allowing for smooth adaptation of backlighting to screen content while maintaining a peaceful peripheral experience by controlling light radiation properties and integration times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fast responding backlighting system is used to extend the screen content, then the immersive viewing experience is improved, but the peripheral view becomes restless and causes eye strain
Solution Approach 1:
The patent applies local quality by differentiating the response behavior of backlighting elements based on their spatial position. Central illumination areas (closer to the display screen) use fast response times to provide immersive screen content extension, while peripheral illumination areas use slow response times to provide relaxed viewing. This spatial differentiation of properties resolves the contradiction between immersion and comfort.
Solution Approach 2:
The backlighting system is segmented into multiple illumination areas with different response characteristics. The system divides the backlighting into central regions (fast response) and peripheral regions (slow response), allowing each segment to serve its specific function independently. This segmentation enables simultaneous fast and slow responding behavior in different parts of the system.
2Object-affected harmful factors
If a slow responding backlighting system is used for relaxed viewing, then eye strain is reduced, but the screen content extension becomes inadequate
Solution Approach 1:
The patent implements local quality by assigning different temporal response characteristics to different spatial zones of the backlighting system. Peripheral areas use slow response times filtered from screen content changes to reduce eye strain, while central areas maintain fast response times for adequate screen content extension. This resolves the contradiction by making response time a spatially varying property.
3Device complexity
If uniform backlighting response time is applied across all illumination areas, then the system is simple to control, but it cannot provide both immersive and relaxed viewing experiences simultaneously
Solution Approach 1:
The patent resolves the complexity-versus-versatility contradiction by implementing local quality through position-dependent response times. The control system automatically adjusts each illumination area's response characteristics based on its position relative to the display screen, providing both immersive and relaxed viewing experiences simultaneously without requiring complex manual configuration.
Solution Approach 2:
The system employs self-service by automatically determining the appropriate response time for each illumination area based on its spatial position. The control unit autonomously filters screen content changes at different rates for different peripheral distances, eliminating the need for user intervention to configure dual viewing modes while achieving both immersion and relaxation.

AI summary
A system suitable for backlighting is provided. The system comprises a monitor unit configured to monitor an information signal, and to generate a first signal based at least partly on the information comprised in the information signal, a control unit configured to control properties of light radiation emitted from at least two illumination areas comprised in the system, based on the first signal and the position of each illumination area in the system, and the integration time of each illumination area depending on the position of each illumination area in the system. The system provides for a more peaceful backlighting effect while still being able to stress action happening on the main screen (e.g. motion). A method and computer-readable medium is also provided.
