Abstract:
(EN) The present application provides a method for determining a touch position and a touch control chip. The method comprises: determining the amount of change in the original data of a capacitive touch screen caused by noise; according to the amount of change in the original data of the capacitive touch screen caused by noise, performing noise processing on a first original value set of the capacitive touch screen, to obtain a first processed data set; and according to the first processed data set, determining a touch position on the capacitive touch screen. The method for determining a touch position and a touch control chip provided in the present application help to improve the accuracy of determining a touch position.
(FR) La présente invention concerne un procédé de détermination d'une position de contact tactile et une puce de commande tactile. Le procédé consiste à : déterminer l'ampleur du changement dans les données d'origine d'un écran tactile capacitif provoqué par le bruit ; en fonction de l'ampleur du changement dans les données d'origine de l'écran tactile capacitif provoqué par le bruit, effectuer un traitement du bruit sur un premier ensemble de valeurs d'origine de l'écran tactile capacitif, pour obtenir un premier ensemble de données traitées ; et selon le premier ensemble de données traitées, déterminer une position de contact tactile sur l'écran tactile capacitif. Le procédé de détermination d'une position de contact tactile et une puce de commande tactile selon la présente invention aident à améliorer la précision de détermination d'une position de contact tactile.
(ZH) 本申请提供了确定触摸位置的方法和触摸控制芯片。该方法包括:确定噪声对电容触摸屏的原始数据引发的变化量;根据噪声对电容触摸屏的原始数据引发的变化量,对电容触摸屏的第一原始值集合进行噪声处理,得到第一处理数据集合;根据第一处理数据集合,确定电容触摸屏上的触摸位置。本申请提供的确定触摸位置的方法和触摸控制芯片,有助于提高触摸位置的准确率。
