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 aesthetic appeal.
Innovation Solution
The design incorporates a display panel with a window featuring a front area and a side area bent at a curvature, including multiple light emission areas arranged in a stair shape along the curved edge of the corner display area, with larger surface areas for the second display area to minimize distortion and enhance image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a display device with curvature is constructed, then the aesthetic appeal and display area are improved, but image distortion occurs in the curved areas
Solution Approach 1:
The patent applies different light emission area configurations to different regions of the display panel. Specifically, the corner display area uses a stair-shaped arrangement of light emission areas, while edge display areas use linear arrangements, and the central area uses a standard grid pattern. This local differentiation allows each region to be optimized for its specific geometric characteristics, reducing image distortion in curved areas while maintaining overall display quality.
Solution Approach 2:
The display panel is divided into distinct regions: corner display areas, edge display areas, and a central display area. Each region is further segmented into multiple light emission areas that are independently configured. This segmentation enables tailored optimization of light emission patterns for each region's specific curvature requirements, thereby minimizing distortion while achieving the desired curved aesthetic.
2Area of stationary object
If the display area is expanded to include curved edges, then the non-display area is reduced, but image quality deteriorates due to distortion
Solution Approach 1:
Different light emission area configurations are applied to different regions: corner display areas use stair-shaped arrangements, edge display areas use linear arrangements, and the central area uses a standard grid. This localized optimization ensures that each region's light emission pattern matches its geometric characteristics, maintaining image quality while maximizing the display area including curved portions.
Solution Approach 2:
The patent transitions from a two-dimensional flat display area to a three-dimensional curved display surface by arranging light emission areas in stair-shaped and linear patterns that follow the curvature. This dimensional adaptation allows the display to maintain image quality across curved surfaces by accounting for the third dimension in the light emission geometry.
3Manufacturing precision
If light emission areas are arranged in a stair shape along curved edges, then image distortion is minimized, but the device complexity increases
Solution Approach 1:
The stair-shaped light emission area arrangement is applied only to corner display areas where curvature-induced distortion is most severe, while edge areas use simpler linear arrangements and the central area uses a standard grid. This localized application of complex patterns minimizes overall device complexity while achieving distortion reduction where it is most needed.
Solution Approach 2:
Rather than applying complex stair-shaped arrangements to the entire display panel, the patent applies this pattern only to corner regions where it is most effective. This partial application reduces the overall complexity increase while still achieving the primary goal of minimizing image distortion in curved areas.
