摘要： Sensitivity of a stylus pen to a touch panel is stabilized. The stylus pen (3) includes a pen tip (31) which is provided to be movable in an axial direction in accordance with a writing pressure and a writing pressure sensor (31d) which generates a signal corresponding to the amount of movement of the pen tip (31). A threshold updating circuit (40) is provided to update a threshold for determining, by the writing pressure sensor (31d), presence or absence of the writing pressure on the basis of a distance between the stylus pen (3) and the touch panel.

摘要： A touch panel controller is equipped with a control unit that outputs a decimation signal to a drive line driving circuit when touch response magnitude data is a designated value or greater, or in other words, when the distance between a touch panel and a stylus pen is closer than a designated value. Thus, it is possible to realize a touch panel system able to moderate the amount of power consumed when synchronizing drive timings between the pen and the touch panel controller that drives the touch panel, and thereby operate with low power consumption.

摘要： In a touch panel system of the present invention, a touch pen is configured of an electronic pen that signals can be input into and output from. A touch panel controller includes a synchronization signal transmission unit that transmits a synchronization signal to the electronic pen during synchronization signal transmission periods immediately before each of a first signal line drive period and a second signal line drive period. The synchronization signal transmission unit transmits the synchronization signal of which the waveform is configured of a Manchester-coded pseudorandom sequence having periodicity to the electronic pen during the synchronization signal transmission period. The electronic pen includes a synchronization signal detecting unit that detects the synchronization signal.

摘要： Provided is a touch panel system capable of minimizing the possibility of a stylus pen failing to detect a synchronization signal. A touch panel controller (4) in the touch panel system generates a preparation signal including a high state and a low state that acts as a reference for adjusting the reception sensitivity of the synchronization signal in the stylus pen, and outputs the preparation signal to the touch panel earlier than the timing at which to output the synchronization signal to the touch panel.

摘要： In a touch panel system (1) of the present invention, a stylus pen (3) produces output that indicates that a quantitative characteristic value is increased from the characteristic value of a previous output by using a waveform that corresponds to an (L+1)-th drive line (DLL+1) other than L numbers of drive lines (DL1 to DLL) and, meanwhile, produces output that indicates that the quantitative characteristic value is decreased from the characteristic value of the previous output by using a waveform that corresponds to an (L+2)-th drive line (DLL+2) other than the L numbers of drive lines (DL1 to DLL). A touch panel controller (10) includes a conversion output unit (19) that converts and outputs the quantitative characteristic value by using the sum of the initial value of the quantitative characteristic value and the number of outputs × the unit amount of increase or decrease in the waveform that corresponds to the (L+1)-th drive line (DLL+1) or in the waveform that corresponds to the (L+2)-th drive line (DLL+2).

摘要： Driving of a stylus pen is satisfactorily controlled even when the touch panel controller and the stylus pen are not connected through a wire. A touch panel (2) is driven by a touch panel controller (4), and is given with an input operation from a stylus pen (3) that is able to transmit and receive information to and from the touch panel controller (4) via wireless communication. The touch panel controller (4) includes a timing generator (14) that generates a synchronization signal to synchronize drive timing of the stylus pen (3) and drive timing of the touch panel (2) with each other, and an information signal generating unit (19) that generates an information signal representing a drive state of the touch panel (2). The information signal is transferred from the touch panel controller (4) to the stylus pen (3) subsequent to the synchronization signal.
