TOUCH SENSOR AND DISPLAY DEVICE INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18398014 titled 'TOUCH SENSOR AND DISPLAY DEVICE INCLUDING THE SAME
The touch sensor described in the patent application consists of a substrate, an insulating layer, a sensor, and sensing lines. The substrate has a sensing region and a peripheral region at the periphery of the sensing region. The insulating layer on the substrate includes contact holes. The sensor overlaps the sensing region on the substrate, while the sensing lines overlap the peripheral region and are connected to the sensor. Each sensing line is a multilayer structure with different widths, consisting of a first electrically conductive layer on the substrate and a second electrically conductive layer connected to the first layer via a contact hole.
- The touch sensor includes a multilayer structure for the sensing lines, enhancing sensitivity and accuracy.
- Different widths of the sensing lines allow for varied touch sensitivity across the sensor.
- The sensor overlaps the sensing region, ensuring precise touch detection.
- The insulating layer with contact holes facilitates the connection between the layers of the sensing lines.
- The peripheral region and sensing lines provide comprehensive coverage for touch detection.
Potential Applications: - Consumer electronics such as smartphones, tablets, and laptops - Automotive touchscreens - Industrial control panels - Medical devices for touch input
Problems Solved: - Improved touch sensitivity and accuracy - Enhanced user experience with touch interfaces - Increased reliability of touch input devices
Benefits: - Higher precision in touch detection - Customizable touch sensitivity levels - Improved durability and longevity of touch sensors

Questions about touch sensors: 1. How do multilayer sensing lines improve touch sensitivity? 2. What are the potential drawbacks of touch sensors with different widths of sensing lines?
Original Abstract Submitted
A touch sensor includes a substrate, an insulating layer, a sensor, and sensing lines. The substrate includes: a sensing region, and a peripheral region at a periphery of the sensing region. The insulating layer is on the substrate. The insulating layer includes contact holes. The sensor is on the substrate and overlaps the sensing region. The sensing lines are on the substrate and overlap the peripheral region. The sensing lines are connected to the sensor. Each of the sensing lines is formed as a multilayer structure. The multilayer structure includes a first electrically conductive layer on the substrate, and a second electrically conductive layer connected to the first electrically conductive layer via a contact hole among the contact holes. Widths of the sensing lines are different from one another.
