    • Provided is a display device equipped with a touch panel, including a front panel arranged above a capacitive touch panel at a predetermined distance away therefrom, in which the touch panel includes a plurality of X electrodes and a plurality of Y electrodes, and the X electrodes are sequentially applied with pulse signals and the Y electrodes receive the pulse signals. When an arbitrary point on the front panel is touched, the touch panel computes a touched point on the touch panel by using both the received pulse signals obtained from the Y electrodes in a case where the front panel is not deformed and the received pulse signals obtained from the Y electrodes in a case where the front panel is deformed. With this, an erroneous operation in which a measurement value is lowered to finally disappear is prevented.
    • 本发明提供了一种配备有触摸面板的显示装置,其包括前面板,其布置在电容式触摸面板上方一定距离处,其中触摸面板包括多个X电极和多个Y电极,并且X电极 依次施加脉冲信号,Y电极接收脉冲信号。 当前面板上的任意点被触摸时,触摸面板在前面板不变形的情况下使用从Y电极获得的接收到的脉冲信号来计算触摸面板上的触摸点,并且获得所接收的脉冲信号 在前面板变形的情况下,从Y电极。 由此,防止测量值降低到最终消失的错误操作。

    • Provided is a touch panel which completes touch detection within a specified time even when the maximum number of touch points is set to be large. A control portion assigns priorities for being given a high coordinate precision to the respective touch points based on the state of the touch points. The control portion selects coordinate calculation algorithms having coordinate precisions corresponding to the priorities of the respective touch points from among a plurality of coordinate calculation algorithms, and calculates required calculation time for calculating coordinates of all the touch points. The control portion determines the priorities so that the calculated required calculation time is equal to or shorter than a specified time. The control portion selects coordinate calculation algorithms corresponding to the priorities and calculates the coordinates of the respective touch points.
    • 提供一种触摸面板,即使在触摸点的最大数量被设定为较大时,也能在规定时间内完成触摸检测。 基于触摸点的状态,控制部分为各个接触点分配给予高坐标精度的优先级。 控制部分从多个坐标计算算法中选择具有与各个触摸点的优先级相对应的坐标精度的坐标计算算法,并且计算用于计算所有触摸点坐标的所需计算时间。 控制部分确定优先级,使得所计算的所需计算时间等于或小于指定时间。 控制部分选择与优先级对应的坐标计算算法,并计算各个触摸点的坐标。
