About This Product

■Capacitive sensor- Capacitive sensors do not generate static electricity that pops when you touch a door or something.
・This is a method of detecting the position of the touched part by capturing changes in the surface charge of the display panel by touching it with your finger.
・A low-voltage electric field is formed across the entire surface of the touch sensor, and the electric field is discharged by the finger that touches it.
・This current is extremely weak and has no effect on the human body.
・Compared to the resistive film method, there are fewer materials involved, and in the resistive film method, the ITO is brought into contact with the ITO and energized, so it is necessary to maintain an air space in between to prevent short circuits when no touch is applied. Transparency and cost were also not good.
・Capacitive sensors have good permeability because they have few components and no air space, and are expected to become mainstream in the future.

■CapacitanceCapacitance is a measure of how much electrical energy a conductor can store. When a human finger, which has dielectric properties (the ability to attract electrons), comes close to a conductor (such as a keypad) that stores electrical energy, the electrical energy flows into the person, changing the capacitance of the keypad. Capacitive sensing technology detects the position and movement of a finger based on changes in capacitance.

The sensor part consists of a grid-shaped X electrode and Y electrode, and electrical energy is stored between the electrodes. Under no operation, the two electrodes form a stable electric field. However, when a human finger, which serves as a grounding device, comes into close proximity, the electric field changes and the capacitance value of the area touched by the finger decreases. This phenomenon occurs due to the electrical conductivity of the human body. The X electrode and Y electrode can detect multi-step changes in capacitance depending on the settings.

It senses that your finger is touching it even if you don't press it hard. Next is the coordinate detection function that detects finger movements. The coordinate detection unit detects the approach of the finger and scans the X and Y electrodes. The capacitive keypad can be operated simply by touching it, without putting any strain on the operating surface. As a result, there is almost no quality deterioration of the operating section, and high reliability can be maintained.
