摘要
Abstract
In the process of pressure sensitivity test and calibration under the screen of mobile handheld terminal equipment(mobile phones,tablets),due to the limitation of the structure of the test module itself,variations of the pressure of all the coordi-nate positions to be calibrated cannot be collected.During the actual test,according to the change of the coordinates of the dotted po-sition of the module,the calibration system needs to match the calibration coefficients of the same position to obtain the test pressure value through calculation.This paper proposes a new solution for pressure-sensing detection under large-area screen.Based on the MLS(Moving Least Squares)algorithm,the irregular surface constructed by variations of the pressure of the node coordinate posi-tion collected by the module is used for surface fitting to obtain variations of the pressure at the full screen coordinate position.The optimal selection of the influence radius and weight function in the algorithm is determined through numerical experiments.The nu-merical experiment results meet the calibration accuracy requirements and realize the full-screen pressure-sensing calibration.关键词
