Dynamic Resolution Control for Display Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices transmit high-resolution contents regardless of the user's environment, leading to unnecessary resource wastage and inefficient data usage, as users cannot distinguish between good and poor display quality beyond a certain resolution level, and different environments may require lower resolutions.
Innovation Solution
A display device and system that transmit resolution control signals to adjust content resolutions based on the user's environment, using sensors to detect changes in display mode and environment, ensuring optimal display quality by adjusting text, image, and video resolutions accordingly, and connected via a wireless network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high-resolution contents are transmitted regardless of use environment, then display quality is improved, but data usage efficiency deteriorates and resource wastage increases
Solution Approach 1:
The system dynamically adjusts content resolution based on real-time sensing of use environment conditions (display mode, orientation, viewing distance) rather than transmitting fixed high-resolution contents. The resolution control signal varies dynamically to match actual display requirements, optimizing the balance between display quality and data efficiency.
Solution Approach 2:
The invention changes the resolution parameter of transmitted contents based on detected use environment conditions. When sensing indicates portable or distant viewing conditions, the system transmits lower resolution contents; when fixed or close viewing conditions are detected, higher resolution contents are transmitted, thus adapting the resolution parameter to actual needs.
2Measurement precision
If high-resolution contents are transmitted for all environments, then display quality is improved, but communication bandwidth utilization deteriorates
Solution Approach 1:
The communication bandwidth utilization is optimized by dynamically adjusting content resolution based on sensed use environment. The system transitions between different resolution levels (high, medium, low) according to real-time conditions, ensuring bandwidth is used efficiently without sacrificing necessary display quality for each specific context.
Solution Approach 2:
The resolution parameter of transmitted contents is changed based on use environment detection. The system selectively transmits high-resolution contents only when necessary (fixed display mode, close viewing), and lower resolution contents when sufficient (portable mode, distant viewing), thus optimizing communication bandwidth utilization.
3Measurement precision
If resolution is increased beyond user distinction capability, then display quality is improved, but resource wastage increases
Solution Approach 1:
The system applies partial action by transmitting only the resolution level necessary for each use context rather than always transmitting maximum resolution. When sensing indicates portable or distant viewing, it transmits lower resolution contents that are sufficient for that context, avoiding the excessive transmission of high-resolution data that cannot be distinguished by users in those conditions.
4Measurement precision
If fixed high-resolution contents are transmitted, then display quality is improved, but adaptability to different environments deteriorates
Solution Approach 1:
The system achieves environmental adaptability through dynamic resolution adjustment based on sensed conditions. It transitions between different resolution levels (high, medium, low) according to detected use environment such as display mode and viewing conditions, making the content delivery adaptable rather than fixed.
Solution Approach 2:
The resolution parameter of transmitted contents is changed according to use environment detection. The system adapts by transmitting high-resolution contents for fixed display mode and low-resolution contents for portable mode, thus achieving versatility across different environments while maintaining appropriate display quality for each context.

AI summary
A display device is connected to a contents providing device via a network. The display device includes a display unit that displays contents; and a display controller that controls a contents display operation of the display unit. The display controller transmits a resolution control signal to the contents providing device, and receives contents data that is converted in response to the resolution control signal from the contents providing device.
