Touch panel, pressure touch device and electronic equipment

Abstract

The invention provides a touchpad and an electronic device. The touchpad and the electronic device have excellent structural performance. The touchpad comprises a circuit board, the upper surface of the circuit board is provided with a touch electrode layer, and the circuit board is used for sensing the touch position of a finger when the finger touches or presses the touchpad and outputting a corresponding touch sensing signal; the support is arranged below the circuit board and comprises a main body part and four extension parts extending from four corners of the main body part to the direction away from the main body part, and cantilever beams are arranged at the tail ends of the extension parts; the pressure sensor is arranged between the circuit board and the bracket, is positioned on the cantilever beam and is used for generating deformation when a pressing force generated when a finger touches or presses the touch panel is transmitted to the cantilever beam and outputting a corresponding pressure sensing signal; and the touch controller is mounted and fixed on the circuit board, is electrically connected with the touch electrode layer and the pressure sensor, and is used for determining the touch position of a finger on the touchpad and the pressing force of the finger according to the touch sensing signal and the pressure sensing signal.

Description

technical field [0001] Embodiments of the present application relate to the field of touch control, and more particularly, to a touch panel, a pressure touch device, and an electronic device. Background technique [0002] A touchpad is a device that senses the position and movement of a user's finger through a touch sensor, thereby controlling the movement of a pointer on a display interface. The traditional touchpad detects the user's pressing action through physical buttons, and performs functions such as confirmation or calling up a menu. However, the conventional touchpad can only detect the pressing action in less than 1 / 2 of the area, and cannot detect the pressing action in any area of ​​the entire touchpad. [0003] The pressure touchpad is a new alternative to the traditional touchpad. It replaces the physical buttons with a pressure detection device and an actuator to realize functions such as function confirmation and call up menus, which solves the problem that ...

AI Technical Summary

Problems solved by technology

The internal structure of the touchpad affects the vibration feeling when the user presses on different positions of the touchpad, and affects the reliability of the touchpad when it is pressed. Therefore, how to reasonably design the structure of the touchpad to improve the user's touch And pressing experience, become a problem that needs to be solved
