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.
