Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional color filter substrate structure is used, then the manufacturing process is simple, but static electricity accumulates in the color filter substrate leading to decreased display quality and performance
Solution Approach 1:
An electrostatic discharge wire layer is introduced as an intermediary component between the black matrix layer and the substrate. This wire layer provides a dedicated conductive pathway that mediates the discharge of static electricity from the color filter substrate to ground electrodes, preventing charge accumulation while maintaining substrate integrity
Solution Approach 2:
The substrate structure is segmented into functionally distinct layers: the black matrix layer for light absorption, the electrostatic discharge wire layer for charge dissipation, and ground electrodes for charge reception. This segmentation allows each layer to perform its specific function optimally, with the wire layer specifically addressing static electricity issues without compromising other substrate functions
2Object-affected harmful factors
If the electrostatic discharge wire layer is added to the color filter substrate, then static electricity is effectively discharged, but the manufacturing process becomes more complex
Solution Approach 1:
The electrostatic discharge wire layer is merged with the black matrix layer in the layer structure, with both layers positioned on the substrate. This merging approach allows the ESD functionality to be integrated into the existing substrate architecture rather than adding completely separate components, facilitating a more streamlined manufacturing process

AI summary
A color filter substrate, a display panel and a display device are provided. The color filter substrate includes a first substrate, a black matrix layer located on the first substrate, and an electrostatic discharge wire layer located on the black matrix layer and connected to the black matrix layer. In the color filter substrate, the display panel and the display device, the electrostatic discharge wire layer is arranged on the black matrix layer of the color filter substrate. Hence, static electricity in the color filter substrate is discharged via the electrostatic discharge wire layer, and accordingly, the static electricity may not be accumulated in the color filter substrate, thereby improving the quality and performance of a display.
