A Touch Panel is a sensor type device fabricated by forming a transparent electrode on a substrate of glass or film.
There are different types of touch panels such as capacitive, resistive, IR, etc.Futaba only develops/produces Capacitive Touch Panel which recognizes the touched coordinates by a change in the touch capacitance.
The touch panel is typically used in conjunction with a display device such as a LCD.
When you touch the screen of the touch panel, the position coordinates/operation information is processed by a microprocessor and related software.This provides an intuitive user interface by directly touching the screen without any input devices required such as a keyboard or mouse.
The adoption of a touch panel for home appliances, vehicles, smartphones, etc. has become widespread. Consequently, providing a touch panel on the display is essential.
