Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses face challenges in designing shapes and combining functions, particularly in displaying images in areas where electronic components are arranged, without compromising the display quality or increasing the panel's complexity.
Innovation Solution
A display panel with a substrate featuring a main display area, a component area, and a peripheral area, where main subpixels and pixel circuits are arranged in the main display area, auxiliary subpixels and pixel circuits are arranged in the component area, and scan connection lines connect the main and auxiliary pixel circuits, allowing image display even in areas with electronic components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display area is extended to include the component area, then the display functionality is improved, but the complexity of signal transmission increases
Solution Approach 1:
The display panel is divided into a main display area and a component area with auxiliary display area, allowing independent control and signal transmission paths. Scan lines are segmented into first scan lines for main pixel circuits and second scan lines for auxiliary pixel circuits, reducing signal transmission complexity while extending display functionality.
Solution Approach 2:
The patent extends display functionality by utilizing the component area, which is traditionally non-display, as an auxiliary display area. This spatial dimension expansion allows additional display content without interfering with the main display area's signal transmission paths.
2Area of stationary object
If scan lines are extended to connect auxiliary pixel circuits, then the display area is extended, but the risk of signal interference increases
Solution Approach 1:
Scan lines are divided into separate first scan lines connecting main pixel circuits and second scan lines connecting auxiliary pixel circuits. This segmentation isolates signal transmission paths, preventing interference between main and auxiliary display areas while extending the overall display area.
Solution Approach 2:
The patent introduces separate scan line structures as intermediaries between the main display area and component area. These dedicated second scan lines act as mediators for signal transmission to auxiliary pixel circuits, isolating them from the main scan line signals to prevent interference.
3Area of stationary object
If auxiliary pixel circuits are arranged in the component area, then the display area is extended, but the manufacturing complexity increases
Solution Approach 1:
The display panel structure is segmented into main display area with main pixel circuits and component area with auxiliary pixel circuits. Each area has its own pixel circuit arrangement and scan line connections, allowing standardized manufacturing processes to be applied to each segment independently, reducing overall manufacturing complexity despite the extended display area.
