Problem
Current AMOLED display panels have large bezels that fail to meet user requirements.
Innovation Solution
A display panel design featuring a substrate layer with a thin film transistor (TFT) layer, a gate on array (GOA) drive circuit, and an auxiliary circuit, where the auxiliary circuit is positioned between the GOA drive circuit and the TFT layer, with notches and organic layers to reduce bezel width and enhance flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If the GOA drive circuit is disposed beside the TFT layer with a bending region, then the bezel width is reduced, but the auxiliary circuit layout becomes more complex
Solution Approach 1:
The auxiliary circuit is segmented into multiple parts: a first auxiliary circuit disposed in the bending region and a second auxiliary circuit disposed in the non-bending region. This segmentation allows the circuit to adapt to the different structural requirements of each region, enabling bezel width reduction while maintaining circuit functionality without excessive complexity in any single region.
Solution Approach 2:
The auxiliary circuit extends from the bending region into the non-bending region, utilizing the spatial dimension beyond the immediate bending area. This dimensional extension provides additional space for circuit layout, reducing the complexity constraints in the bending region itself while achieving the desired narrow bezel width.
2Length of stationary object
If the auxiliary circuit is disposed in the bending region, then the bezel width is reduced, but the circuit flexibility and reliability are compromised
Solution Approach 1:
The auxiliary circuit is divided into a first auxiliary circuit in the bending region and a second auxiliary circuit in the non-bending region. The first auxiliary circuit handles the bending zone with appropriate flexibility design, while the second auxiliary circuit in the rigid non-bending region provides stable electrical connections, thus maintaining overall reliability while achieving narrow bezel width.
Solution Approach 2:
The first auxiliary circuit acts as an intermediary between the bending region and the non-bending region, adapting the circuit path to accommodate the structural transition. This intermediary section bridges the gap between flexible and rigid zones, maintaining circuit functionality and reliability across the bezel edge.
