DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240272742 titled 'DISPLAY DEVICE
Simplified Explanation:
The patent application describes a display device with an input sensor that includes multiple layers and electrodes for sensing touch input.
- The input sensor consists of a first insulating layer, a sensing electrode, and a signal line connected to the sensing electrode.
- The signal line is made up of a first metal layer and a second metal layer, with the first metal layer having higher electrical conductivity and the second metal layer having higher hardness.
- A dummy electrode is placed between sensing electrodes, with multiple portions spaced apart from each other.
Key Features and Innovation:
- Multi-layer input sensor design for accurate touch input detection.
- Use of different metal layers for improved electrical conductivity and hardness.
- Inclusion of a dummy electrode to enhance touch sensitivity.
Potential Applications:
- Touchscreen devices such as smartphones, tablets, and laptops.
- Interactive displays for kiosks, ATMs, and public information systems.
Problems Solved:
- Improved touch input accuracy and sensitivity.
- Enhanced durability and longevity of the input sensor.
Benefits:
- More precise touch input recognition.
- Longer lifespan of the display device.
- Enhanced user experience with responsive touch controls.
Commercial Applications:
The technology can be utilized in the development of advanced touchscreen devices for consumer electronics, public information systems, and interactive kiosks, potentially leading to improved user interaction and device longevity.
Questions about Display Device Technology:
1. How does the use of different metal layers in the signal line impact the performance of the input sensor? 2. What are the potential challenges in implementing a multi-layer input sensor design in commercial display devices?
Original Abstract Submitted
a display device includes a display panel and an input sensor on the display panel. the input sensor includes a first insulating layer, a sensing electrode, and a signal line electrically connected to the sensing electrode and under the first insulating layer. the signal line includes a first metal layer and a second metal layer on the first metal layer. the first metal layer has higher electrical conductivity than the second metal layer, and the second metal layer has a higher hardness than the first metal layer. a dummy electrode is between sensing electrodes. the dummy electrode includes a plurality of portions spaced apart from each other.
