Cut Display Panel Data Pad Layout for Flexible Resolution Cuts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The cutting display panel manufacturing method often fails to connect output terminals of a data driving integrated circuit (IC) to data lines of a cut-out display panel, preventing the driving of the display panel when the mother substrate is cut in the vertical direction to achieve desired resolutions.
Innovation Solution
A cutting display panel design with a mother substrate featuring gate lines and data lines, where first and second block data pads are electrically connected to data lines, allowing for the use of gate-in-panel (GIP)-type gate drivers and source driver ICs with different output channels to enable flexible cutting and resolution adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the mother substrate is cut in the vertical direction to achieve desired resolutions, then the display panel can meet customer demand for various resolutions, but the output terminals of the data driving IC cannot be connected to the data lines of the cut-out display panel
Solution Approach 1:
The data pad structure is segmented into first block data pads and second block data pads, where each block corresponds to a specific group of data lines. This segmentation allows the display panel to be cut at different positions while ensuring that the remaining data pads remain properly connected to their corresponding data lines, thus maintaining connection reliability across various cutting scenarios and resolution requirements.
Solution Approach 2:
The data pads are pre-configured in block structures on the mother substrate before cutting occurs. By anticipating potential cutting positions and pre-organizing the data pad connections accordingly, the design ensures that regardless of where the vertical cut is made, the output terminals of the data driving IC will always be properly connected to the appropriate data lines in the cut-out display panel.
2Adaptability or versatility
If the data pad structure is modified to enable flexible cutting for various resolutions, then the display panel can meet different customer demands, but the device complexity increases
Solution Approach 1:
The data pad structure is divided into multiple blocks, where each block corresponds to a specific group of data lines. This segmentation allows for modular organization, making the complex structure more manageable and systematic. Each block can be independently configured and connected, reducing the overall complexity while maintaining flexibility for various cutting positions and resolution requirements.
Solution Approach 2:
The block data pad structure serves multiple functions: it enables flexible cutting for various resolutions, ensures proper connection reliability, and provides a systematic organization for data line grouping. By designing the data pads to be universally applicable across different cutting scenarios, the patent reduces the need for multiple specialized structures, thereby managing complexity while maintaining adaptability.
