Display Apparatus Corner Pattern Control for Non-Right Angles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices with quasi-quadrangular shapes, having corners with non-right angles, face challenges in displaying images effectively as existing technologies struggle to manage the unique corner shapes, leading to incomplete information display and aesthetic issues.
Innovation Solution
A display device with a signal controller that detects specific patterns in partial regions of the image corresponding to non-right angular corners, controls the display to avoid crossing these corners, and uses a light blocking member to prevent light leakage, ensuring all image information is displayed without distortion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a general quadrangular display area is used, then the manufacturing and design are simple, but the corner regions cannot effectively display image information due to non-right angular shapes
Solution Approach 1:
The display area is segmented into multiple regions: a first region corresponding to the non-right angular corner area and a second region corresponding to the remaining area. This segmentation allows different image processing strategies to be applied to different regions, enabling effective use of the corner area while maintaining overall system manageability.
Solution Approach 2:
The patent transforms the 2D image display problem into a 3D spatial problem by considering the corner region as a distinct spatial dimension that requires special handling. By detecting patterns in the corner region and adjusting display accordingly, the system effectively utilizes the unique geometric properties of the non-right angular corner.
2Shape
If the display area includes non-right angular corners, then aesthetic appeal and modern design are improved, but light leakage occurs at the corner regions
Solution Approach 1:
A light blocking member is introduced as an intermediary element positioned at the corner region of the display area. This member selectively blocks light in the non-right angular corner area while allowing light to pass through the rest of the display area, thereby preventing light leakage without compromising the overall aesthetic shape.
Solution Approach 2:
The light blocking property is applied locally only to the corner region where non-right angular shapes create light leakage problems, while the rest of the display area maintains its normal light transmission properties. This localized approach preserves the aesthetic appeal of the overall shape while eliminating the harmful light leakage effect.
3Manufacturing precision
If the display controller processes the entire image uniformly, then processing is simple, but image distortion occurs at the corner regions of non-right angular shapes
Solution Approach 1:
The image processing system applies different processing strategies to different regions: the first region (corner area) receives specialized processing including pattern detection and selective display control, while the second region (remaining area) receives standard uniform processing. This local differentiation eliminates image distortion at corners while keeping the overall processing system manageable.
Solution Approach 2:
The system performs preliminary detection of specific patterns in the corner region before displaying the image. By detecting patterns such as text or important visual elements in advance, the system can proactively adjust the display parameters for the corner region to prevent distortion, rather than attempting to correct distortion after it occurs.
