1. A touch detection device comprising:
a panel comprising a plurality of electrodes regularly arranged in rows and columns;
a connector configured to electrically connect some of the plurality of electrodes to form a plurality of sensing channels;
a plurality of drivers configured to provide driving signals to the plurality of sensing channels; and
a main controller configured to control the plurality of drivers,
wherein the main controller controls the plurality of drivers so that at least one of the plurality of drivers starts input sensing at a different time,
wherein the main controller is configured to provide driving start signals so that a rising edge of one driving start signal provided to any one or more of the plurality of drivers coincides with a falling edge of another driving start signal provided to one or more other drivers of the plurality of drivers, and
wherein a first time period between the rising edge of the one driving start signal and a first falling edge generated right before the rising edge is different from a second time period between the rising edge of the one driving start signal and a second falling edge generated right after the rising edge.
