Touchpad
TouchPad (TouchPad or TrackPad) is an input device widely used on laptop computers. It uses sensing the movement of the user's fingers to control the movement of the pointer.
The touchpad can be regarded as a mouse replacement. Touchpads can also be found on some other portable devices, such as personal digital assistants and some portable audio and video devices. Due to design constraints, touchpads are usually no larger than 20 square centimeters. Among them, the multi-touch touchpad equipped on Apple's MacBook Pro is the most outstanding, which can be used for gestures such as zooming in and out of the display, as well as handwriting input.
It takes advantage of Apple's multi-touch technology. This technology was first developed and patented by FingerWorks (a small company in San Francisco, later acquired by Apple), and was later first applied to the iPhone.
The working principle of the touch panel
The touch panel uses a printed circuit board to form an array of rows and columns; the printed board and the surface plastic film are bonded with strong double-sided tape, and its sensing The detection principle is capacitive sensing. A special integrated circuit board under the surface of the touch panel continuously measures and reports this trajectory to detect the movement and position of the finger.
Touch chip
"Touch" specifically refers to single-point or multi-point touch technology; the chip is an IC, which means that the end surface can be connected with the friction lining and friction material layer An integrated metal sheet or non-metal sheet generally refers to all electronic components. It is a circuit module that integrates a variety of electronic components on a silicon board to achieve a specific function.
It is the most important part of electronic equipment, responsible for computing and storage functions. The application scope of integrated circuits covers almost all electronic equipment for military and civilian use. A small piece of silicon containing integrated circuits, often part of a computer or other device.
