Problems solved by technology

[0003] However, the capacitance on a capacitive touch screen will not only change due to human touch, but also due to changes in the environment (such as humidity, dust, electric field, etc.)
For example, when the power supply interference in the use environment is large, it will cause the drift of the capacitive screen, and the touch may be inaccurate (such as the jumping of the report point) and affect the accuracy of the operation.

Abstract

The invention provides a touch screen correcting method and device. The method comprises the following steps: acquiring touch events occurring on a touch screen; responding the touch events to obtain a report point information assemble of the touch screen, wherein the report point information assemble is an information assemble of a plurality of report points triggered by the tough events; determining a touch region according to the report point information assemble; and removing report points out of the touch region. Therefore, report point information generated due to external power interference can be filtered, and the antijamming capability of the touch screen and the accuracy of the report points are improved.

Description

technical field [0001] The present invention relates to the technical field of touch screens, in particular to a touch screen calibration method and device. Background technique [0002] With the development of science and technology, electronic products such as mobile phones and tablet computers are more and more common in daily life. There are also more and more mobile phones and tablet computers using capacitive touch screens. Capacitive touch screen technology uses the induction effect of human body current to realize the operation of the device. When the human body touches the capacitive touch screen, the capacitance here will change, and the capacitive touch screen determines the next action according to the position where the capacitance changes. [0003] However, the capacitance on the capacitive touch screen will not only change due to human touch, but also due to changes in the environment (such as humidity, dust, electric field, etc.). For example, when the pow...
