Abstract: A touch screen panel and a driving method thereof. The touch screen panel includes a touch pad unit including a plurality of receiver pads and a plurality of transmitter pads combined with the receiver pads, and a touch sensing unit for determining a touch position, based on changes in mutual capacitance between the receiver pads and the transmitter pads. The touch sensing unit determines maximum values for every column by scanning touch sensing signals in the column direction of the touch pad unit, decides whether rows having maximum values for every column are the same, when the rows having the maximum values for every column are not the same, determines a greatest value by comparing all values of the scanned touch sensing signals, and determines touch coordinates through a combination of transmitter and receiver pads corresponding to the position at which the greatest value exists.

Abstract: A touch sensor device includes first electrode patterns arranged in a first direction and physically separated first electrode cells; second electrode patterns arranged in a second direction crossing the first direction and includes physically separated second electrode cells; first touch signal lines connected to the first electrode cells; second touch signal lines connected to the second electrode cells; and a touch sensor controller connected with the first touch signal lines and the second touch signal lines. The first electrode cell and the second electrode cell adjacent in the first direction form a channel for generating position information by a mutual capacitive method. The touch sensor controller stores a ghost table including a ghost ratio for each channel for a touch position, and removes a ghost from measured touch data by using the ghost table to generate final touch data.

Abstract: A sensor device includes: first sensors; second sensors which forms a capacitance with the first sensors; and a sensor driver which transmits driving signals to the first sensors through first sensor lines, and receives sensing signals from the second sensors through second sensor lines. The sensor driver sequentially transmits the driving signals to the first sensors, and transmits, during each period of transmitting the driving signals, an offset signal, which is identical in frequency to and different in phase from the driving signals, to at least one selected from first sensors which does not receive the driving signals among the first sensor. The sensor driver sets at least one selected from a slew rate and a voltage level of the offset signal to a value different from a corresponding value of a corresponding driving signal.
