20090183931 | TOUCH PANEL DEVICE - A touch panel unit includes a plurality of electrodes arranged in directions of an X axis and a Y axis. A screening electrode switching control circuit handles each of electrodes arranged in the direction of the X axis as a detecting electrode and handles electrodes arranged in the direction of the Y axis as screening electrodes when an arithmetic unit detects the location of an approach or a touch to or with the touch panel unit in the direction of the X axis, whereas the screening electrode switching control circuit handles the electrodes arranged in the direction of the X axis as the screening electrodes and handles each of the electrodes arranged in the direction of the Y axis as the detecting electrode when the arithmetic unit detects the location of the approach or the touch to or with the touch panel unit in the direction of the Y axis. | 07-23-2009 |
20090189877 | TOUCH PANEL DEVICE AND USER INTERFACE DEVICE - An analog touch panel device capable of utilizing a two-point touch on a touch panel as meaningful information input and a user interface device employing the analog touch panel device are provided. A decision is made as to whether two points are touched or not on a touch panel TP having resistive films which have electrode terminals at opposite end portions each and are superimposed top and bottom in such a manner that the electrode terminals become orthogonal, in which the top and bottom resistive films are brought into contact with each other by a push of a resistive film surface by touch input. The decision is made according to resistance values between the opposite terminals, and when a decision is made that the two points are touched, the distance between the two points touched is detected according to the resistance values between the opposite terminals. | 07-30-2009 |
