Screen calibration method and screen calibration apparatus

The invention relates to a screen calibration method and a screen calibration apparatus. The screen calibration method comprises the steps of: acquiring the current environmental parameter value of the touch screen of a terminal; calculating the change value of the current environmental parameter value of the touch screen; automatically calibrating the screen when the change value of the current environmental parameter value of the touch screen is up to a preset threshold value. The technical solution can achieve real-time monitoring of the current environmental parameter value of the touch screen of the terminal, timely calibrates the touch screen according to the change of the current environmental parameter value of the touch screen, and avoids false point report, caused by the external envrionment, of the touch screen of the terminal, so that the accuracy of touch screen point report is improved, and the user experience is improved.
