Flexible Display Driving Circuit Pad Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flexible splicing display apparatuses experience poor display quality due to the arrangement of connection pads on multiple sides of flexible display devices, which affects the display status when devices are spliced together.
Innovation Solution
The driving circuit and flexible display device configuration where data and scan signal wires are connected within the display region and led to one side of the driving chip, minimizing the impact of connection pads on display quality and ensuring seamless gamma and colorimetric values across spliced regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If connection pads are disposed on multiple sides of the flexible display device, then the signal connection is achieved, but the display quality is downgraded due to the impact on spliced status
Solution Approach 1:
The connection pads are segmented and concentrated on only one side of the flexible display device rather than being distributed on multiple sides. This segmentation allows the connection region to be isolated to a specific area, preventing it from affecting the display status of adjacent spliced regions while maintaining signal connection functionality.
2Area of stationary object
If flexible display devices are spliced to form large size display apparatus, then the display size is increased, but the display quality of the spliced apparatus is poor due to connection pad arrangement
Solution Approach 1:
The connection pads are extracted and concentrated to one side of the flexible display device, separating the connection function from the display region. This extraction ensures that when multiple devices are spliced together, the connection regions do not interfere with the display status of adjacent devices, thereby maintaining high display quality across the entire spliced apparatus.
3Reliability
If data signal wires and scan signal wires are connected to multiple sides, then the signal transmission is achieved, but the number of connection regions affecting display status increases
Solution Approach 1:
The connection pads for both data signal wires and scan signal wires are merged and concentrated on a single side of the flexible display device. This merging reduces the number of connection regions from multiple sides to just one, minimizing the impact on display status when devices are spliced while maintaining reliable signal transmission through the consolidated connection area.
