    • An apparatus and method for changing a touch mode in a device having a touch screen including a plurality of touch sensors is provided. In a method for changing a touch mode in the device, the device determines a variation in the influx of electric charges during a time period in a charging process, and determines whether the variation exceeds a given critical value. If the variation exceeds the critical value, the device operates the touch screen in a self capacitive touch mode using the touch sensors as sending ends for sending the electric charges in order to detect a touch event. Therefore, the device of a mutual capacitive touch type can detect a touch event by using the self capacitive touch mode even in unstable power environments.
    • 提供一种用于改变具有包括多个触摸传感器的触摸屏的设备中的触摸模式的装置和方法。 在用于改变装置中的触摸模式的方法中,装置确定在充电过程中的一段时间内电荷的流入的变化,并且确定变化是否超过给定的临界值。 如果变化超过临界值,则设备使用触摸传感器作为用于发送电荷的发送端来以自身电容触摸模式操作触摸屏,以便检测触摸事件。 因此,即使在不稳定的电力环境中,互电容式触摸式的装置也可以通过使用自电容式触摸模式来检测触摸事件。

    • A terminal having a touch screen and a method for identifying a touch event thereon are provided. The method includes determining a sensed location of a touch event on a touch screen when the touch event is sensed, calculating a maximum changed value of a touch signal of a center node and a changed value of a touch signal of at least one peripheral node, the peripheral node being located around the center node at the sensed location, and determining whether the touch event is a hovering event of an input tool proximate to the touch screen according to the calculated maximum changed value and the calculated changed value of the touch signal of the at least one peripheral node. The terminal may analyze a touch signal changed according to an input tool in order to identify a type of the touch event. Accordingly, the terminal may identify an unintentional touch event.
    • 提供具有触摸屏的终端和用于识别触摸事件的方法。 该方法包括当感测到触摸事件时确定触摸屏幕上的触摸事件的感测位置,计算中心节点的触摸信号的最大改变值和至少一个外围节点的触摸信号的改变值, 所述外围节点位于感测位置处的中心节点周围,并且根据所计算的最大改变值和所计算的触摸信号的改变值来确定触摸事件是否是靠近触摸屏的输入工具的悬停事件 所述至少一个外围节点。 终端可以分析根据输入工具改变的触摸信号,以便识别触摸事件的类型。 因此,终端可以识别无意触摸事件。
