Abstract: The present invention calculates a first detected position influenced by the palm and an accurate second detected position from which the influence of the palm is eliminated immediately after a touch-on is judged, and calculates a correction value based on the first detected position and the second detected position. In a period from the point at which the touch-on is judged to the point at which a touch-off is judged, the first detected position influenced by the palm is calculated once successively, and the first detected position is corrected by the correction value to calculate a third detected position to improve the position accuracy at the time of the drag operation thereby.

Abstract: A display device has a data-holding circuit with a capacitance and a display portion with a plurality of pixel electrodes, formed on a first carrier substrate. In the display device, a second carrier substrate disposed opposite the first carrier substrate is placed above the display portion, but the opposing substrate is not present above the area in which the data-holding circuit is disposed. The parasitic capacitance of the data-holding circuit can thereby be reduced. Therefore, the capacitance in the data-holding circuit can be reduced and the area required can be reduced as well. The display data of all the pixels is sent serially to the liquid crystal module without high-speed transfer for each frame time interval, and size can be reduced because the controller IC and interface circuit are formed on the same substrate as the display device substrate.

Abstract: The ion sensors using TFT or MOSFET are low in the measurement sensitivity so that it is difficult to detect an extremely small amount of sensing-target substance. A TFT ion sensor includes both a gate electrode (a silicon substrate) and a reference electrode, in which the electrostatic capacitance of a gate insulating film (a thermal oxide film) is set to be larger than the electrostatic capacitance of an ion sensitive insulating film. Therefore, it is possible to detect the concentration of ions, hormones, and the like in a sensing-target substance from the shift in the threshold voltage of the gate-source voltage to source-drain current property.
