Display Pixel Layout With Shared Data Lines to Reduce Dead Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses have a significant dead space due to the arrangement of scan and data drivers outside the display area, leading to inefficient use of space.
Innovation Solution
The display apparatus incorporates a shift register distributed within the display area, with scan lines and data lines arranged to reduce dead space by sharing connections between pixel sets and using distributed circuits to supply scan signals, allowing for a more compact design.

Engineering Contradiction Analysis
1Ease of manufacture
If the scan driver and data driver are arranged outside the display area, then the drivers can be easily manufactured and maintained, but the dead space increases significantly
Solution Approach 1:
The patent applies dimensionality change by transitioning from a two-dimensional arrangement (drivers outside the display area) to a three-dimensional integration (drivers distributed within the display area across multiple layers). The shift register is divided into first and second distributed circuits disposed at different positions, with connection wires routing signals through the third dimension (vertical layering), thereby utilizing spatial depth to reduce the horizontal dead space while maintaining driver functionality.
Solution Approach 2:
The scan driver is segmented into first and second distributed circuits that are distributed within the display area rather than concentrated outside it. This segmentation allows the driver functionality to be distributed across multiple locations, reducing the dead space while maintaining the ease of manufacture through modular circuit design.
2Area of stationary object
If the shift register is distributed within the display area, then the dead space is reduced, but the device complexity increases
Solution Approach 1:
The shift register is segmented into first and second distributed circuits that are distributed within the display area. This segmentation reduces dead space by utilizing otherwise unused regions, while the modular nature of segmented circuits actually simplifies the overall device complexity compared to a monolithic driver structure.
Solution Approach 2:
The distributed circuits within the display area serve multiple functions: they act as shift register stages for scan signal generation and also utilize the available space efficiently. The connection wires perform dual roles by connecting distributed circuits while also routing signals through the display area, thereby reducing dead space without proportionally increasing complexity.
3Area of stationary object
If data lines are shared between pixel sets, then the spatial efficiency is improved, but the signal distribution complexity increases
Solution Approach 1:
Data lines are merged to be shared between the first and second pixel sets. This merging reduces the total number of data lines required, thereby improving spatial efficiency by reducing the dead space. The shared data lines are routed through the display area, utilizing space that would otherwise be unused, while the signal distribution complexity is managed through the modular distributed circuit architecture.
