Display Scanning Control With Variable Priority Screen Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices are limited by a fixed scanning rate, which restricts smooth operation in scenarios requiring faster scanning rates, such as gaming, without the ability to differentiate between important and non-important screen areas.
Innovation Solution
The display device includes a processor that dynamically adjusts the scanning rate by dividing the screen into multiple pixel lines for non-important areas and single pixel lines for important areas, allowing for variable size, position, and number of these areas based on content analysis and user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If constant scanning rate is used for entire screen, then manufacturing simplicity is maintained, but scanning speed cannot be increased for important areas
Solution Approach 1:
The screen is divided into multiple pixel line groups, where each group can be scanned independently at different rates. Important areas are assigned to specific pixel line groups that can be scanned faster than the global constant rate, while maintaining overall screen coverage. This segmentation enables differential scanning rates without requiring complete system redesign.
Solution Approach 2:
Different scanning rates are applied to different regions of the screen based on their importance. The processor identifies important areas and allocates higher scanning rates to the corresponding pixel line groups, while less important areas maintain the base scanning rate. This local optimization improves overall perceived performance without uniformly increasing complexity across the entire display system.
2Productivity
If multiple pixel lines are scanned simultaneously in first area, then scanning rate is improved, but area coverage is reduced
Solution Approach 1:
The system dynamically adjusts the number of pixel lines scanned simultaneously based on content analysis and user preferences. The processor can vary the extent of multi-line scanning in the first area according to different scenarios, balancing between scanning efficiency and area coverage. This dynamic adjustment allows the system to optimize for speed when needed while preserving coverage when important content is present.
3Ease of operation
If scanning rate is increased for game content, then user satisfaction is improved, but energy consumption increases
Solution Approach 1:
The system changes the scanning parameter (number of pixel lines scanned simultaneously) based on the type of content being displayed. When game content is detected, the processor increases the scanning rate by scanning multiple pixel lines in parallel for the relevant areas. This parameter adjustment is content-dependent, allowing high performance for games while avoiding unnecessary energy consumption during other content types.

AI summary
A method of controlling a display device may comprise: identifying a first area among all areas of a content displayable on a display; and scanning multiple pixel lines by multiple pixel lines in the first area and scanning one pixel line by one pixel line in a second area among all the areas of content which remain after excluding the first area, wherein at least one of a size and a position of the first area and a number of first areas is variable.
