Curved Corner Display Panel Layout for Distortion Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices with curvature often exhibit image distortion in curved areas, limiting their ability to maintain image quality and reduce non-display peripheral areas.
Innovation Solution
A display device design featuring a window with a front and side area bent at a curvature, incorporating a display panel with distinct light emission areas arranged in a stair shape along the curved edge of the corner display area, and driving circuits strategically positioned to minimize distortion and reduce the non-display area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a display device is designed with a curved window and display panel, then the non-display peripheral area is reduced and aesthetic performance is improved, but image distortion occurs in the curved areas
Solution Approach 1:
The display panel is divided into a first display area (flat) and a second display area (curved), with further segmentation into edge display areas and corner display areas. This segmentation allows different regions to be optimized independently, with the corner display area being further subdivided into multiple pixel rows that are selectively disposed to minimize distortion while reducing non-display area.
Solution Approach 2:
Different regions of the display panel are assigned different qualities and configurations. The corner display area specifically uses a stair-shaped light emission area arrangement with varying pixel densities and orientations tailored to the local curvature requirements, rather than applying a uniform design across the entire curved surface.
2Manufacturing precision
If light emission areas are arranged in a stair shape along the curved edge, then image distortion is minimized, but device complexity increases
Solution Approach 1:
The light emission areas in the corner display area are arranged in a stair shape that follows the curved edge of the display panel. This curved arrangement adapts to the spherical/curved geometry of the display, allowing pixels to be positioned optimally along the curved surface to maintain image quality and minimize distortion.
Solution Approach 2:
The stair-shaped arrangement of light emission areas creates an asymmetric pattern in the corner display area, with pixel rows disposed at different positions and orientations. This asymmetric configuration is specifically designed to counteract the distortion caused by curvature, rather than using a symmetric or uniform pixel arrangement.
3Area of stationary object
If the display area is expanded to include curved corners, then the overall display area increases, but image quality deteriorates due to distortion
Solution Approach 1:
The corner display area is segmented into multiple pixel rows (first through fourth pixel rows) with different configurations. By selectively disposing pixels in specific rows and using a stair-shaped light emission area arrangement, the design expands the display area into the curved corner while maintaining image quality through localized optimization of pixel placement.
Solution Approach 2:
The display panel transitions from a two-dimensional flat surface to a three-dimensional curved surface. The stair-shaped light emission area arrangement and selective pixel disposal in different rows accommodate this dimensional change, allowing the display to utilize the curved corner space effectively while maintaining image quality through spatial reconfiguration.
