Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in display devices is to enhance display quality while minimizing the physical space required, as the increasing number of components necessitates efficient arrangement within a limited area.
Innovation Solution
The display device incorporates a substrate with sub-pixels that share a source line, where a symmetric sub-pixel is positioned adjacent to the main sub-pixel, allowing for increased storage capacitor capacity and optimized layout, thereby improving display quality by allocating additional space for signal lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the number of components is increased to improve display quality, then display quality is improved, but the area occupied by components increases
Solution Approach 1:
The patent merges the source lines of adjacent sub-pixels into a single shared source line. Specifically, the source line extends to electrically connect to both the first sub-pixel and the second sub-pixel, eliminating the need for separate source lines for each sub-pixel. This consolidation reduces the total number of conductive lines and the area they occupy, while maintaining proper electrical connectivity for both sub-pixels, thus resolving the contradiction between component count and display quality.
Solution Approach 2:
The shared source line serves multiple functions: it provides electrical connection to both the first sub-pixel and the second sub-pixel simultaneously. This multi-functional design allows a single conductive structure to fulfill what would traditionally require separate structures, thereby reducing the overall area occupied by components while maintaining full functionality for driving multiple sub-pixels.
2Area of stationary object
If components are arranged within a limited area to achieve miniaturization, then device size is reduced, but the efficiency of area utilization must be improved
Solution Approach 1:
By combining the source lines for adjacent sub-pixels into a single shared conductor, the patent reduces the total number of discrete components that need to be arranged within the limited area. This merging allows for more efficient spatial arrangement, as fewer separate elements need to be positioned and connected, thereby improving area utilization efficiency while achieving miniaturization.
Solution Approach 2:
The source line is configured to extend in a direction that allows it to serve multiple sub-pixels arranged in a spatial pattern. By extending the source line to connect to both sub-pixels, the design utilizes the two-dimensional layout more efficiently, allowing components to be arranged in a compact configuration that maximizes area utilization while maintaining electrical connectivity.

AI summary
A display device includes a substrate, a sub-pixel including a transistor including an active pattern disposed on the substrate and a gate electrode disposed on the active pattern and defining a channel area in an area overlapping the active pattern, and a light emitting element disposed on the transistor, a sensing signal line disposed on the gate electrode to overlap the channel area and that transmits a sensing signal to the gate electrode, a source line extending in a first direction, electrically connected to the active pattern, and that transmits an initialization voltage to the active pattern, and a symmetric sub-pixel having a same structure as the sub-pixel, adjacent to the sub-pixel in a second direction intersecting the first direction, and symmetrical to the sub-pixel with respect to an imaginary symmetric line passing through a center of the source line.
