Bent Signal Line Penetrating Conducting Wire Notch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In display panel manufacturing, poor contact between substrates due to overflowing and overlapping alignment liquid affects the yield, as the liquid flows into the peripheral region through notches in conducting wires, causing alignment issues with the sealing layer.
Innovation Solution
The design incorporates a signal line with an included angle between its segments, which prolongs the flow path of the alignment liquid, preventing it from overflowing and overlapping the sealing layer by bending and buffering its flow, thus improving substrate connection and manufacturing yield.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the signal line is arranged straight to penetrate through the notch in the conducting wire, then the manufacturing process is simple, but the alignment liquid flows directly into the peripheral region causing poor contact between substrates
Solution Approach 1:
The signal line is designed with a bent configuration instead of a straight arrangement. The signal line includes a first line segment penetrating through the notch and a second line segment extending from the first line segment at an included angle, forming a curved path that buffers and obstructs the flow of alignment liquid, preventing it from reaching the peripheral region and ensuring good substrate contact.
2Reliability
If the signal line is bent to prevent alignment liquid overflow, then the substrate contact quality improves, but the signal line structure becomes more complex
Solution Approach 1:
The signal line is divided into multiple segments: a first line segment that penetrates through the notch in the conducting wire and a second line segment that extends from the first line segment. The two segments are arranged at an included angle to each other, forming a stepped or bent structure that effectively buffers the alignment liquid flow while maintaining manufacturing feasibility.

AI summary
Disclosed are a display panel and display apparatus. The display panel is divided into a display region and a peripheral region. The display panel includes: a first substrate; a second substrate arranged opposite to the first substrate; an alignment layer at least formed in the display region; and a sealing layer connecting the first substrate to the second substrate. The display panel is provided with a conducting wire group including at least one conducting wire, and the conducting wire includes a notch. The display panel includes at least one signal line. The signal line penetrates through the notch in the conducting wire to be connected to the display region. The signal line includes a first line segment and a second line segment communicated with each other. An included angle is formed between the second line segment and the first line segment which are bent relative to each other.
