摘要: A positioning method and a driving apparatus for a touch panel having a plurality of sense electrodes in an axis direction are disclosed. The driving apparatus detects the sense electrodes to obtain a plurality of sensed values. The driving apparatus counts the number of multiple candidate electrodes, wherein the candidate electrode is an electrode having a sensed value larger than a first threshold value. The first threshold value is increased and the number of the candidate electrodes is counted again if the number of the candidate electrodes is larger than a second threshold value. At least one electrode is selected as a positioning electrode from the candidate electrodes if the number of the candidate electrode is not larger than the second threshold value. A position of a touch point on the touch panel in the axis direction is calculated based on the position and sensed value of the positioning electrode.

摘要: A method and an apparatus for detecting a touch point movement are provided. In the present method, a touch panel is detected to obtain the positions of m previous touch points Pi during a frame period and the positions of n current touch points Pj′ during another frame period. Distances D(i,j) between the previous touch points Pi and the current touch points Pj′ are calculated, and a minimum distance among valid ones of the distances D(i,j) is found out. If a distance D(a,b) among the distances D(i,j) is the minimum distance, the current touch point Pb′ is defined as a touch point moved from the previous touch point Pa, and the distances D(a,1)-D(a,n) and the distances D(1,b)-D(m,b) are defined as invalid values.
