Abstract: A method and an apparatus for improving touch sensitivity of a capacitive type touch screen panel are provided. In the method, the apparatus sequentially drives a plurality of transmitting channels of the touch screen panel using a predetermined scan frequency. The apparatus determines a sequential touch count by simultaneously scanning a plurality of receiving channels of the touch screen panel wherein the sequential touch count is the number of sequentially touched receiving channels. Also, the apparatus specifies a scan unit to be used for dividing the plurality of receiving channels into groups on the basis of the sequential touch count and for sequentially scanning the groups of the receiving channels. The apparatus determines a touch coordinate by sequentially scanning the plurality of receiving channels using the specified scan unit.

Abstract translation: 提供一种用于提高电容型触摸屏面板的触摸灵敏度的方法和装置。 在该方法中，设备使用预定的扫描频率顺序驱动触摸屏面板的多个发送通道。 该装置通过同时扫描触摸屏面板的多个接收通道来确定顺序触摸计数，其中顺序触摸计数是顺序触摸的接收通道的数量。 此外，该装置指定用于根据顺序触摸计数将多个接收信道划分成组并用于顺序地扫描接收信道组的扫描单元。 该装置通过使用指定的扫描单元顺序扫描多个接收通道来确定触摸坐标。
