Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High power consumption in large and high-resolution liquid crystal display devices leads to increased heat and reduced reliability, with dynamic power consumption accounting for 90% of the total power consumption, necessitating a reduction to enhance device reliability and user experience.
Innovation Solution
An image processing method that determines the distance between the display device and the user, compares it with optimum viewing distances for different resolutions, and adjusts the image resolution accordingly, using a correction parameter to select appropriate interpolation modes and resolution levels such as 8K, UHD, FHD, or HD, to optimize power usage while maintaining visual and audio quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high resolution display is used, then visual quality is improved, but power consumption increases
Solution Approach 1:
The patent applies dynamics by making the display resolution adjustable based on viewing distance. The system dynamically switches between different resolution levels (e.g., 8K, 4K, 1080P) according to the detected distance between the user and the display device, rather than maintaining a fixed high resolution. This resolves the contradiction by allowing high resolution only when necessary (close viewing distance) and reducing resolution when not needed (far viewing distance), thereby reducing power consumption while maintaining visual quality when required.
Solution Approach 2:
The patent changes the resolution parameter based on viewing distance conditions. When the user is at a close distance, the system uses high resolution (e.g., 8K) for superior visual quality. When the user moves farther away, the system automatically switches to lower resolution levels (e.g., 4K, 1080P) which consume less power. This parameter adjustment strategy resolves the contradiction between maintaining high visual quality and reducing power consumption by adapting the resolution parameter to actual viewing conditions.
2Measurement precision
If high resolution display is used, then visual quality is improved, but heat generation increases
Solution Approach 1:
The system dynamically adjusts display resolution based on real-time detection of user viewing distance. High resolution modes that generate more heat are activated only when the user is close to the display. When the user is at a farther distance, the system switches to lower resolution modes that generate less heat, thereby controlling temperature while maintaining visual quality when needed.
Solution Approach 2:
The patent changes the display resolution parameter according to viewing distance, which directly controls heat generation. High resolution parameters (e.g., 8K) produce more heat but are used only when close viewing distance is detected. Lower resolution parameters (e.g., 1080P) produce less heat and are used when viewing distance is large, thus resolving the contradiction between visual quality and heat control.
3Measurement precision
If high resolution display is used, then visual quality is improved, but reliability reduces
Solution Approach 1:
The system enhances reliability by dynamically adjusting resolution based on viewing distance. Continuous operation at high resolution, which stresses the display device and reduces reliability, is avoided. Instead, the system switches to lower resolution modes when high resolution is not needed (large viewing distance), reducing operational stress on the device and improving overall reliability while maintaining visual quality when required.
Solution Approach 2:
The patent improves reliability by changing the resolution parameter according to actual viewing conditions. High resolution parameters that stress the device are used only when necessary (close viewing distance). Lower resolution parameters are used during normal operation when viewing distance is large, reducing wear and stress on the display device and thereby improving reliability while preserving visual quality when needed.
4Use of energy by moving object
If resolution is reduced, then power consumption decreases, but visual quality deteriorates
Solution Approach 1:
The system dynamically adjusts resolution based on viewing distance to maintain visual quality while reducing power consumption. When the user is close to the display, high resolution is maintained for superior visual quality. When the user moves away, the system automatically reduces resolution to lower power consumption levels, as the reduced resolution is imperceptible at larger distances. This dynamic adjustment resolves the contradiction by reducing power consumption only when visual quality is not compromised.
Solution Approach 2:
The patent changes the resolution parameter based on viewing distance conditions. High resolution parameters are used when close viewing distance is detected to ensure visual quality. Low resolution parameters are used when viewing distance is large, where the visual quality difference is imperceptible to users, thus achieving power consumption reduction without noticeable deterioration in visual quality.
