Abstract

Provided are a resistive touch panel detection method and apparatus. A resistance variance ratio of a Y plane relative to an X plane is calculated based on voltage detections before touching and after a two-point touch occurs; and then the inclination angle is calculated based on corresponding relationship between the inclination angle and the resistance variance ratio. To obtain a distance between the two points, the present invention the resistance variance ratio and a first ratio of a resistance variance of any one of the X plane and the Y plane relative to a total resistance of the any one plane are calculated; then a second ratio of an equivalent contact resistance at a midpoint relative to the total resistance is calculated; and the distance is calculated based on the resistance variance ratio, the first ratio, the second ratio, and a correlated relationship of the distance between the two points.
