[0115] Refer below figure 1 A touch screen panel according to the first embodiment will be described.

[0116] The touch screen panel according to the present embodiment includes a first resistive film 10 and a second resistive film 20 each formed of a transparent conductive film of ITO (Indium Tin Oxide) or the like. The first resistive film 10 and the second resistive film 20 may be formed on surfaces of respective glass substrates or transparent films. In this case, the glass substrate or the transparent film is arranged such that the first resistance film 10 and the second resistance film 20 are opposed to each other. The XH electrode 11 and the XL electrode 12 are formed along the Y-axis direction at the first end and the second end of the first resistance film 10 along the X-axis direction, respectively. Also, a YH electrode 21 and a YL electrode 22 are formed along the X-axis direction at the first end and the second end of the second resistance film 20 along the Y-ax...

[0238] Next, a second embodiment is described. This embodiment, which seeks to provide a method of detecting a position on a touch screen panel, has a partially different procedure than the first embodiment.

[0239] Refer below Figure 34 A method of detecting a position on a touch screen panel according to this embodiment will be described. First, in step S202, initialization is performed. The details of this initialization will be described below.

[0240] Next, in step S204, it is determined whether the touch screen panel is touched (contacted) with a finger or the like. If finger contact or the like is detected on the touch screen panel (YES in step S204), the process proceeds to step S206. If no finger contact or the like is detected on the touch screen panel (NO in step S204), step S204 is repeated until there is a finger contact or the like on the touch screen panel. Specifically, if a potential is detected via the second resistive film 20 in the case of applying ...

[0347] Next, a third embodiment is described. This embodiment relates to a touch screen panel, and more particularly to a touch screen panel configured to be suitable for use in the position detection methods of the first and second embodiments.

[0348] First, for instantiation in figure 1 The relationship between the first and second resistive films 10 and 20 and the resistors Rx1 and Ry1 in the touch screen panel in . In a touch screen panel, a large difference between the potential detected when one point is pressed and the potential detected when two points are pressed makes it easier to determine whether the touch screen panel is touched at one point or two points .

[0349] The first touch screen panel is described below. Follow the first touch screen panel, as illustrated in the figure 1 Each of the first resistive film 10 and the second resistive film 20 in the touch screen panel is 91.0 mm long along the X-axis direction and 75.0 mm long along the Y-axis directio...

Abstract

A method of detecting a position on a touchscreen panel including a first resistive film having first and second electrodes provided at its corresponding ends in a first direction and a second resistive film having third and fourth electrodes provided at its corresponding ends in a second direction perpendicular to the first direction includes measuring a potential at the first electrode with supply voltage applied to a first resistor connected to the first electrode with the second electrode grounded; measuring a potential at the third electrode with the supply voltage applied to a second resistor connected to the third electrode with the fourth electrode grounded; measuring potentials at the third and fourth electrodes with the supply voltage applied to the first electrode with the second electrode grounded; and measuring potentials at the first and second electrodes with the supply voltage applied to the third electrode with the fourth electrode grounded.
