What are touch screens and touch keys?

Touch screens and touch keys are two different touch technologies. Although they both involve touch input in human-computer interaction interfaces, they are different in implementation methods and uses.

1. Touch screen refers to a device that enables input by touching images or buttons on the screen.

It is a technology that performs touch operations directly on the display panel.

Touch screens are usually based on capacitive touch or resistive touch, and capture coordinate positions by sensing the touch of a finger or stylus to achieve interaction and control.

Touch screens are widely used in consumer electronics (such as smartphones, tablets), computer equipment, vending machines and self-service terminals, industrial control equipment, medical equipment and other fields.

2. TouchKeys refers to a technology that uses touchable buttons or keys to achieve input.

A touch key usually refers to a touch panel that is covered with a film or sensing layer on a physical key. When a finger touches the key, the touch and operation can be sensed and converted into a corresponding signal.

Touch keys are primarily used as buttons or keys in keyboards, remote controls, and other input devices.

In summary, the touch screen is more intuitive and flexible. It can perform multi-touch and gesture operations by touching the screen, and is suitable for scenarios that require interaction on the screen. Touch keys are more suitable for scenarios that require traditional button feel and operation, such as keyboards, remote controls, and other key devices with specific functions.
