Display Circuit Layout with In-Display Shift Registers to Reduce Dead Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses have a significant dead space due to the arrangement of scan drivers and data drivers outside the display area, leading to a large non-emission area.
Innovation Solution
The display apparatus integrates a shift register within the display area, distributing it between pixel sets, and incorporates distributed circuits to supply scan signals to scan lines, reducing the dead space by placing data drivers and shift registers within the display area.

Engineering Contradiction Analysis
1Area of stationary object
If scan driver and data driver are arranged outside the display area, then the display area can be kept simple and drivers are easily accessible, but the dead space increases significantly
Solution Approach 1:
The shift register is nested within the display area by integrating it between pixel sets rather than placing it outside. The distributed circuits are embedded within the display structure, allowing the driving function to be contained within the display area boundaries, thus reducing dead space while maintaining driver functionality
Solution Approach 2:
The shift register is repositioned from a peripheral location (outside display area) to an internal location (between pixel sets within the display area). This spatial reconfiguration utilizes the internal dimension of the display structure, transforming the dead space into functional space without compromising driver accessibility
2Area of stationary object
If shift register is distributed within the display area between pixel sets, then dead space is reduced, but the complexity of the display structure increases
Solution Approach 1:
The shift register is segmented into distributed circuits that are placed between different pixel sets within the display area. This segmentation allows the driving function to be distributed throughout the display structure rather than concentrated in one location, reducing dead space while managing complexity through modular placement
Solution Approach 2:
The distributed circuits serve multiple functions: they act as part of the shift register for scan signal generation, provide driving functionality for adjacent pixel sets, and utilize the space between pixel sets that would otherwise be dead space. This multi-functionality reduces overall system complexity by combining multiple roles into single structural elements
