Abstract

The invention discloses a calibration method for a touch screen, which comprises the steps that first calibration is conducted, and a middle area of the touch screen is calibrated; and second calibration is conducted, a plurality of points are taken from an edge area of a display, at least two points are taken from each edge of the display, and the edge area of the touch screen is calibrated according to coordinate values of the points on the touch screen, display coordinate values originally set for the points, and the linear relation of a mapped line segment of a touch screen line segment on the display. The calibration method for the touch screen, which is provided by the invention, can solve the problem that the edge area of the touch screen can be very inaccurate or simply useless after being calibrated by using the existing calibration method for the touch screen, so the accuracy of the edge area of the touch screen is improved.

Description

technical field [0001] The invention relates to touch screen mapping technology, in particular to a touch screen calibration method. Background technique [0002] Touch screen has become the most user-acceptable computer input method after keyboard, mouse, tablet and voice input due to its many advantages such as ruggedness, durability, easy communication, and beautiful appearance. Utilizing touch screen technology, users can operate the host by lightly touching the icons or text on the display screen with their fingers or stylus, thus making the human-computer interaction more natural and straightforward. This technology greatly facilitates users and has been widely used in handheld consumer electronics products, medical application equipment, vending machines, ticket vending machines, ATM machines, POS machines, industrial and process control equipment and other fields. [0003] Due to the mechanical error and the error of the amplification factor in the resistive touch s...
