Rounded Corner Display Appearance via Pixel Color Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manufacturing display devices with rounded corners is challenging due to the complexity of thin layers of semiconductor materials and the difficulty in maintaining performance and cost efficiency.
Innovation Solution
A display device design that includes a display area with a frame having rounded corners, where specific pixel configurations and ambient lights generate a color similar to the frame, creating the appearance of rounded corners without altering the display's rectangular shape, and allowing user-adjustable curvature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If display devices are manufactured with rounded corners, then aesthetic appeal is improved, but manufacturing complexity and cost increase significantly
Solution Approach 1:
The display device is segmented into distinct functional zones: a rectangular display area and a non-display area with rounded corners. The rounded corners are achieved by trimming the non-display area rather than the display area itself, allowing independent optimization of each zone's manufacturing process
Solution Approach 2:
The appearance of rounded corners is created through optical illusion rather than physical curvature of the display panel. Pixels in the corner regions display colors matching the frame (e.g., black or dark gray) to visually replicate the rounded shape, while the actual display panel maintains its rectangular form for easier manufacturing
2Shape
If display devices are manufactured with rounded corners, then aesthetic appeal is improved, but manufacturing precision requirements increase
Solution Approach 1:
The manufacturing process is segmented so that the display panel is manufactured separately with standard rectangular precision, then the non-display area is trimmed independently to create rounded corners. This separates the precision requirements of the display functionality from the aesthetic corner shaping
Solution Approach 2:
The non-display area is treated as a disposable or sacrificial element that can be trimmed away. By removing the non-display area rather than attempting to manufacture the entire panel with precise rounded corners, the manufacturing precision requirements are significantly reduced while still achieving the desired aesthetic effect
3Area of stationary object
If pixels in corner regions are used to display image content, then screen real estate is maximized, but the appearance of rounded corners is compromised
Solution Approach 1:
Different regions of the display have different functional qualities: the central display area uses full-color image rendering to maximize screen real estate, while the corner pixels use simplified color output (matching the frame color) to create the rounded corner appearance. This local differentiation allows both goals to be achieved simultaneously
Solution Approach 2:
The corner pixels dynamically change their displayed color to match the frame color, creating the visual effect of rounded corners. This color adaptation allows the display area to extend to the edges while maintaining the aesthetic appearance of rounded corners through chromatic camouflage
