Touch Sensors

Providing sensing technologies for various markets from smartphones to automotive

Outline

Our film-based capacitive-type touch sensor is thin and light, while providing high visibility and narrow frames. It has been widely adopted in applications for smartphones, tablet devices, mobility (automotive), portable game players, and industrial equipment across global markets etc.

Key Features

  1. Using film as a base material, it is thinner and lighter than glass sensors so that there is no worry of cracking even if dropped.
  2. Same level on transparency and price as glass sensor.
  3. A wide range of sizes, from smartphones to automotive control panels.
  4. Not only flat panel, curved designs are possible by taking advantages of the characteristics of film.
  5. The Photolithography Process can realize the narrow frame as of glass sensors.

Basic Principle and Structures

Structures

The basic structure of the resistive-type touch sensor consists of two sheets of electrode film on which transparent conducting layers are coated. A slight gap is provided between the two films. When the upper film is pushed with a finger or a stylus pen, the film deflects and the two transparent conducting layers contact each other, then electric current flows into the lower film. The pushed position can be identified by reading out that location. The roles of the micro spacers are prevention from unnecessary contact of two electrode films, and adjustment of the input pressure by its density, etc.

Basic Principle

The electrostatic capacitance between X and Y electrodes changes when fingers touch on that area, and the touched position is detected.

Service System

We can offer not only the sensor alone, but also as the modules that is affixed to cover parts etc. We also flexibly respond with the patterns and configuration designs that match sensor chips selected by customers.
