Mixed-Resolution Display Rendering for Uniform Edge Image Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices face challenges in achieving improved display quality, particularly in areas with lower resolution due to the need for enhanced visual clarity and uniformity across different pixel densities.
Innovation Solution
A display device design that incorporates a first display area with high-resolution pixels and a second display area with lower-resolution pixels, where the controller generates data units of varying resolutions by mixing and averaging data units corresponding to different colors, and drives light emitting elements based on these rendered data units, ensuring improved visibility and uniformity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the display panel uses uniform high-resolution pixels across the entire display area, then the visual clarity in the first display area is improved, but the manufacturing complexity and cost increase due to requiring all pixels to meet the highest resolution specification
Solution Approach 1:
The patent applies local quality by dividing the display panel into different display areas (first display area with high-resolution pixels and second display area with lower-resolution pixels). Each area has pixel resolution optimized for its specific function, allowing the main display area to achieve high visual clarity while edge areas use lower-resolution pixels to reduce overall device complexity and manufacturing costs.
2Device complexity
If the display panel uses lower-resolution pixels in the second display area, then the manufacturing cost and complexity are reduced, but the display quality and visual uniformity deteriorate in the edge areas
Solution Approach 1:
The patent introduces a controller as an intermediary component that receives image data and generates different data units for different display areas. The controller processes and adapts the image data, generating appropriate drive signals for both high-resolution first pixels and lower-resolution second pixels, thereby maintaining display quality uniformity across different resolution zones without requiring complex hardware modifications to the display panel itself.
3Measurement precision
If the controller processes all pixels at the highest resolution, then the image quality is maintained across the entire display, but the processing time and energy consumption increase
Solution Approach 1:
The patent segments the image data processing into different pathways based on display area. The controller divides the incoming image data and processes it differently for the first display area (maintaining high resolution) and the second display area (reducing to lower resolution). This segmentation allows parallel processing at different resolution levels, significantly reducing the total processing time and energy consumption compared to processing all pixels at maximum resolution.

AI summary
Provided is a display device including a display panel including first pixels disposed in a first display area and including first light emitting elements having a first resolution, and a second pixel disposed in a second display area adjacent to the first display area and including second light emitting elements having a second resolution lower the first resolution, and a controller that receives input image data including first data units corresponding to the first light emitting elements and second data units corresponding to the second light emitting elements. The second data units have the first resolution. The controller generates third data units having the second resolution by rendering the second data units. The second light emitting elements are driven based on the third data units.
