TOUCH SENSING UNIT, DISPLAY DEVICE AND MANUFACTURING METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240192799 titled 'TOUCH SENSING UNIT, DISPLAY DEVICE AND MANUFACTURING METHOD THEREOF
The patent application describes a touch sensing unit that reduces contact defects between conductive layers in a touch signal line. The unit includes a substrate, a touch electrode in a sensor area, and a touch signal line extending to a peripheral area. The touch signal line has a first conductive layer on the substrate, a second conductive layer on top with an insulating layer in between, and a contact hole connecting the two layers. The first layer contains materials like Mo, MoNb, Ti, or Ta, while the second layer contains Al or AlNb.
- The touch sensing unit minimizes contact defects between conductive layers in a touch signal line.
- It includes a touch electrode, substrate, first and second conductive layers, and an insulating layer.
- The first layer consists of materials like Mo, MoNb, Ti, or Ta, while the second layer contains Al or AlNb.
- The second layer is in contact with the first layer through a contact hole in the insulating layer.
Potential Applications:
- Touchscreen devices
- Consumer electronics
- Automotive touch panels
Problems Solved:
- Minimizes contact defects in touch signal lines
- Improves touch sensitivity and accuracy
Benefits:
- Enhanced performance of touch sensing units
