Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices with rounded corners face challenges in applying the same data voltage to pixel circuits located in mutually different rows and columns, necessitating a solution to ensure uniform image display across these areas.
Innovation Solution
The display device incorporates a main light emitting part, a sub-light emitting part, a main pixel circuit, a sub-pixel circuit, a main data line, a sub-data line, and bridge lines to connect these components in a manner that allows for the application of the same data voltage to pixel circuits in different rows and columns, with specific distances and orientations to facilitate voltage transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If pixel circuits are arranged in mutually different rows and columns at rounded corners, then the display area is optimized and dead space is reduced, but the data voltage cannot be uniformly applied to all pixel circuits
Solution Approach 1:
The patent introduces bridge lines as intermediary conductive structures to connect data lines to pixel circuits located in mutually different rows and columns. These bridge lines serve as mediators that enable uniform voltage application to pixel circuits that would otherwise be difficult to reach, solving the contradiction between optimized display area and reliable voltage application.
Solution Approach 2:
The patent extends the data transmission path into the third dimension by routing data lines through multiple layers and using bridge lines to reach pixel circuits in different rows and columns. This dimensional approach allows the same data voltage to be delivered to pixel circuits that would traditionally require separate data lines, maintaining uniform voltage application while optimizing display area.
2Area of stationary object
If sub-light emitting parts are placed in the peripheral area, then dead space is reduced and image display is extended, but the complexity of data line routing increases
Solution Approach 1:
The patent designs bridge lines that serve multiple functions: they connect data lines to pixel circuits, extend the data transmission path to peripheral area sub-light emitting parts, and maintain signal integrity across different rows and columns. This multi-functionality reduces the need for separate dedicated routing paths, thereby reducing overall device complexity while expanding display area.
Solution Approach 2:
The patent merges the data line routing function with the bridge line structure, combining what would traditionally be separate components into a unified conductive path. This merging simplifies the overall data transmission system while enabling sub-light emitting parts to be placed in the peripheral area, thus expanding display area without proportionally increasing complexity.
