Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices with curved display areas, such as circular or oval shapes, exhibit unnatural content presentation due to the matrix arrangement of pixels, leading to distorted visuals in curved and boundary areas.
Innovation Solution
A display driver integrated circuit that applies color transformation values based on the distance from a specified point on the display, smoothing the color transition from the curved area to the blank area through the boundary area, ensuring a natural and smooth visual experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If display elements are arranged in a matrix form, then manufacturing and control become simpler, but the curved display area appears unnatural and distorted
Solution Approach 1:
The patent applies different color transformation values to different regions of the display based on their distance from a specified point. The display area is divided into multiple regions, and each region receives customized color transformation processing to compensate for the distortion caused by matrix arrangement in curved displays.
Solution Approach 2:
The patent changes the color transformation parameters dynamically based on the distance from a specified point. By adjusting color transformation values according to position, the system compensates for the visual distortion in curved areas while maintaining the simplicity of matrix pixel arrangement.
2Adaptability or versatility
If a curved display area is implemented, then design flexibility and visual appeal improve, but color distortion and unnatural appearance occur
Solution Approach 1:
Different color transformation values are applied to different locations on the display based on their distance from a specified point. This local customization of color parameters compensates for the distortion inherent in curved display geometries.
Solution Approach 2:
The color transformation values are pre-calculated and stored in a lookup table based on distance from a specified point. This preliminary preparation allows the display system to quickly apply the correct color compensation without real-time complex calculations.
3Manufacturing precision
If color transformation values are applied based on distance, then visual naturalness in curved areas improves, but processing complexity increases
Solution Approach 1:
Color transformation values are pre-calculated and stored in a lookup table during the design phase. This preliminary action eliminates the need for complex real-time calculations during display operation, reducing processing complexity while maintaining visual quality.
Solution Approach 2:
The display area is segmented into multiple regions based on distance from a specified point. Each segment is assigned a specific color transformation value, simplifying the processing by dividing the complex color correction task into manageable discrete segments.
