Author:Faismars Click: Time:2021-12-02 15:30:35

Touch screen calibration, test methods and linear tests are listed below for users to perform touch screen calibration and touch positioning tests. The user can press the function button to complete the calibration or test.

1. Linear curve test

The linearity of the touch screen is listed on this page for reference and troubleshooting purposes.

2. Four-point calibration

It needs to be calibrated before the touch screen works accurately. When the user feels that the accuracy is not enough, the calibration can be done again. Press this button, a calibration window will pop up, guiding the user to do a 4-point calibration.

When the flashing X symbol appears on the screen, press the X symbol exactly until the X symbol no longer flashes. Follow the on-screen prompts to click the 4 X symbols. In addition, there is a time bar at the bottom of the window. Please click the X symbol before the time progress bar is completed. If there is no click during this period, the calibration task will be automatically terminated.

3. Clear and calibrate

Pressing this button will clear the linear parameters obtained after the 25-point calibration and repeat the 4-point calibration. Since the 4-point calibration data will be invalid after the 25-point calibration data is cleared, it needs to be re-doed for four-point calibration.

4. Linear settings

The linear calibration (25 or 9 points) function is used to compensate for the linear relationship of the touch screen. After the linear calibration is completed, the linearity of the touch screen will be visually displayed in the linear curve window.

Press this button, a calibration window will pop up, guiding the user to do a 25-point calibration.

When the flashing X symbol appears on the screen, press the X symbol exactly until the X symbol no longer flashes. Follow the on-screen prompts to click on the 25 X symbols. In addition, there is a time bar at the bottom of the window. Please click the X symbol before the time progress bar is completed. If there is no click during this period, the calibration task will be automatically terminated.

5. Test Development

This feature is used for accuracy and performance checks. When the touch screen is mapped to the contact system, a new window will open as shown below at this location.

The user presses the "clear" button to clear the window and presses the "exit" button to terminate the test.
