    • An indicated position detecting apparatus includes a display module having a display screen, and a plurality of microphones to detect a contact sound to the display screen. The plurality of microphones are arranged at an outer peripheral portion of the display screen to be apart from each other. A time difference acquisition unit acquires arrival time differences of the contact sound between two microphones in each of two combinations of the plurality of microphones. A positional information acquisition unit derives two hyperbolas corresponding to the arrival time differences acquired by the time difference acquisition unit, each hyperbola having focal points at the two microphones in each of the two combinations of the plurality of microphones, and acquires an intersection of the two derived hyperbolas as information of a position where the contact sound is generated.
    • 指示位置检测装置包括具有显示屏的显示模块和用于检测与显示屏幕的接触声音的多个麦克风。 多个麦克风被布置在显示屏的外周部分以彼此分开。 时差获取单元获取多个麦克风的两个组合中的每一个中的两个麦克风之间的接触声音的到达时间差。 位置信息获取单元导出对应于由时差获取单元获取的到达时间差的两个双曲线,每个双曲线在多个麦克风的两个组合中的每一个中的两个麦克风处具有焦点,并且获取两个 导出的双曲线作为产生接触声音的位置的信息。

    • A resistive film type touch panel includes first and second resistive films respectively provided on the inner surfaces of a pair of substrates on the touch side and the opposite side, protruding contacts which are provided on the first resistive film so as to protrude to a predetermined height, and come into contact with the second resistive film upon bending/deformation of the touch-side substrate by a touch to electrically connect the touch-side substrate to the second resistive film, insulating spacers which are arranged between the substrates except the positions of the protruding contacts, and define the space between the substrates to a height higher than that of protruding contacts, and a liquid or liquid crystal sealed in the space between the substrates. This arrangement reduces the bending/deformation amount of the touch-side substrate and the refraction of transmitted light at a portion bent/deformed by a touch on the touch-side substrate.
    • 电阻膜式触摸面板包括分别设置在触摸侧和相对侧上的一对基板的内表面上的第一和第二电阻膜,设置在第一电阻膜上以突出到预定高度的突出触点 并且通过触摸使得触摸侧基板弯曲/变形而与第二电阻膜接触以将触摸侧基板电连接到第二电阻膜,绝缘间隔件布置在基板之间,除了位置之外 突出的触点,并且将基板之间的空间限定为高于突出触点的高度,以及密封在基板之间的空间中的液体或液晶。 这种布置减少了触摸侧基板的弯曲/变形量以及通过触摸侧基板上的触摸而弯曲/变形的部分的透射光的折射。
