Bendable Corner Display Panel Layout for Expanded Screen Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display panels face challenges in expanding the display area while maintaining a compact and flexible design, particularly in incorporating a bendable corner display area that effectively utilizes the available space.
Innovation Solution
The display panel incorporates a bendable corner display area arranged to correspond to the corner of a front display area, featuring a substrate with a front display area, a corner display area, and a middle display area. This configuration includes pixels, gate and data driving circuits, and connection lines that overlap the display areas, allowing for efficient use of space and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a bendable corner display area is added to expand the display area occupancy, then the display area is increased, but the device complexity increases due to additional substrate structures and wiring configurations
Solution Approach 1:
The display panel is divided into distinct functional zones: a front display area with pixels, a corner display area with bent substrate and embedded wiring, and a middle display area. This segmentation allows the corner region to be independently configured with bendable substrate and integrated wiring, enabling display area expansion without complicating the entire panel structure.
Solution Approach 2:
The corner display area utilizes a bent substrate configuration that extends the display area into a curved dimension. The substrate is bent at a predetermined angle to form a corner region, allowing the display to occupy three-dimensional space more effectively and increase overall display area occupancy without proportionally increasing planar footprint.
2Area of stationary object
If connection lines are arranged to overlap display areas to improve space utilization, then the space efficiency is improved, but the manufacturing precision requirements increase due to precise alignment needs
Solution Approach 1:
The connection lines are pre-configured to extend from the peripheral area through the middle display area to the front display area during the manufacturing process. By establishing these connections in advance during substrate fabrication, the alignment is locked in before final assembly, reducing the need for high-precision post-manufacturing alignment operations.
Solution Approach 2:
The middle display area serves as an intermediary zone that facilitates the connection between the peripheral area (containing driving circuits) and the front display area. Connection lines are routed through this intermediate region, allowing for gradual transitions and easier alignment during manufacturing while still achieving high space utilization by overlapping with the display area.
3Adaptability or versatility
If a bendable corner display area is implemented to enhance aesthetic appeal and user experience, then the visual appeal is improved, but the ease of manufacture decreases due to complex bending and wiring integration
Solution Approach 1:
The substrate is designed with specific bending parameters including a predetermined bend angle and radius of curvature. By optimizing these geometric parameters during the design phase, the substrate can be bent to form the corner display area using standard manufacturing processes, reducing the complexity of implementation while achieving the desired aesthetic effect.
Solution Approach 2:
The corner display area integrates multiple functions into a single structure: the bent substrate itself serves as both the structural element and the mounting surface for connection lines and display elements. This merging of structural and functional elements reduces the number of separate manufacturing steps and simplifies the overall fabrication process.
