Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices have limitations in extending the display area while maintaining a seamless visual experience, as the boundary between display areas can be visually recognizable, and the compact arrangement of electrical components is challenging.
Innovation Solution
The display device incorporates a substrate with first and second display areas that appear as a single display region, along with a non-display area where electrical components like scan drivers are disposed in compact overlapping configurations to maximize display areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the display area is extended by adding a second display area adjacent to the first display area, then the total display area is increased, but a boundary between the first and second display areas becomes visually recognizable
Solution Approach 1:
The patent merges the first and second display areas into a single visual display region by positioning light emitters in the second display area to overlap with electrical components (scan driver, data driver, controller) in the non-display area. This overlapping configuration allows the second display area to extend into the non-display area, creating a seamless visual experience without a recognizable boundary between the two display areas.
Solution Approach 2:
The patent utilizes the vertical dimension (z-axis) by positioning light emitters to overlap with electrical components in the non-display area. This three-dimensional arrangement allows the display area to extend into the non-display area without creating a visual boundary, effectively adding display area while maintaining visual seamlessness.
2Area of moving object
If electrical components are arranged in compact overlapping configurations to maximize display areas, then the display area is increased, but the arrangement of electrical components becomes more complex
Solution Approach 1:
The patent resolves the complexity issue by utilizing the vertical dimension to overlap light emitters with electrical components. Instead of arranging components side-by-side in the planar dimension, the light emitters are positioned to overlap with the scan driver, data driver, and controller in the non-display area, achieving compact configuration without excessive planar complexity.
Solution Approach 2:
The patent employs multiple sets of scan lines (first scan line set, second scan line set, third scan line set, fourth scan line set) that follow similar routing patterns through the second display area to reach the scan driver. This systematic copying of line configurations simplifies the overall design while achieving the compact overlapping arrangement.
3Area of moving object
If the second light emitter overlaps the second circuit and scan driver, then the display area is extended into the non-display area, but the electrical component layout becomes more challenging
Solution Approach 1:
The patent segments the scan lines into multiple sets (first, second, third, fourth scan line sets) with different routing configurations. The second scan line set and fourth scan line set cross the second display area to connect to the scan driver, while the first and third scan line sets connect to circuits in the second display area. This segmentation allows flexible routing that accommodates the overlapping configuration of light emitters with electrical components.
Solution Approach 2:
The patent employs dynamic routing of scan lines that can cross the second display area or connect to circuits within it, depending on the specific line set. This flexible, dynamic approach to line routing enables the light emitters to overlap with electrical components while maintaining ease of manufacture through systematic routing patterns.
