Abstract

The invention discloses a touch key circuit board function display and detection system. The system comprises a touch key circuit board detection device and a touch key circuit board function display circuit, wherein the touch key circuit board function display circuit is placed in the touch key circuit board detection device and is connected to a to-be-tested touch key circuit board on the touch key circuit board detection device. By connecting the mechanical touch key circuit board detection device to the to-be-tested touch key circuit board and communicating the display circuit, various input signals, for example, switching value, analog quantity, resistance variation amount and capacitance variation amount on the touch key are gathered, and the output signals control various indicating and sound image apparatuses on the touch key to work. As a display and test platform, the system disclosed by the invention not only can be used for displaying functions and performances of various thin film keys, but also can be used for an actual test in engineering.

Description

technical field [0001] The invention relates to a function display and detection system of a touch button circuit board. Background technique [0002] In the field of automatic detection and control, inductive touch technology has been widely used. At present, the more popular inductive touch technologies are mainly divided into four types: resistive, capacitive inductive, infrared and surface acoustic wave. The most commonly used in the industrial field are resistive and capacitive sensing. [0003] Resistive sensing touch technology uses two transparent conductive layers-ITO (nano indium tin oxide) coated between the surface layer and the base layer. When the pressure generated by the touch will make the two conductive layers connect, press different points , the resistance value from the point to the output terminal is also different, so the voltage signal (analog quantity) corresponding to the position of the point will be output, and the coordinate values ​​of x and Y ...
