Abstract

The invention relates to a linear test machine of a capacitance touch screen, which comprises a working platform, a movable touch and scratch device and a control system, wherein the capacitance touch screen to be measured can be placed at the top surface of the working platform, and the control system is connected with the movable touch and scratch device by a data line and can receive the output of the capacitance touch screen to be measured by a serial port. The linear test machine of the capacitance touch screen is characterized in that the movable touch and scratch device comprises an X-direction movement device, a Y-direction movement device, a Z-direction movement device and an induction pen device, wherein the Y-direction movement device is arranged on the working platform and can carry out linear back-and-forth movement in a Y direction on the working platform; the X-direction movement device is arranged on the Y-direction movement device and can carry out linear back-and-forth movement in an X direction; the Z-direction movement device is arranged on the X-direction movement device and can vertically slide up and down; and the induction pen device is arranged at the X-direction movement device and can touch and scratch the capacitance touch screen to be measured. The invention has high test accuracy and real-time property, simple structure and convenient use and can carry out accurate and comprehensive linear test on the capacitance touch screen.

Description

technical field [0001] The invention relates to a capacitance touch screen linearity testing machine. Background technique [0002] Touch screen panels are currently a popular input device for electronic products. Nowadays, many 3C products such as mobile phones, PDAs, MP3s, museum guide facilities, and many other equipment input information by touching the display screen. After the popularity of resistive touch screens, there has been another upsurge in the development of capacitive touch screens in the industry. When Apple launched the first generation of capacitive products, various touch screen companies stepped up research and development efforts, resulting in capacitive touch screens being in vogue. But so far, how to monitor the electronic performance of the capacitive touch screen has become a difficult problem in the industry. Existing technologies are basically limited to resistive touch screens, and there are few linear tests involving capacitive touch screens. ...
