A touch sensing device comprising: drive circuitry configured to: apply a first drive signal to a first drive line of a plurality of drive lines during a first time period; and apply a second drive signal to a second drive line of the plurality of drive lines during a second time period, the second time period at least partially overlapping the first time period during an overlapping time period, wherein the first and second drive signals have a same frequency; and sense circuitry configured to: detect a sense signal from at least one sense line, the sense signal being related to the first and second drive signals by capacitive coupling and affected by touch or proximity of one or more objects to one or more sensing points associated with the at least one sense line, a sensing point being associated with at least one of the plurality of drive lines and at least one of a plurality of sense lines; and derive touch information for the one or more sensing points from the sense signal; characterised in that the first and second drive signals are in phase during a first portion of the overlapping time period and out of phase during a second portion of the overlapping time period. drive circuitry configured to: apply a first drive signal to a first drive line of a plurality of drive lines during a first time period; and apply a second drive signal to a second drive line of the plurality of drive lines during a second time period, the second time period at least partially overlapping the first time period during an overlapping time period, wherein the first and second drive signals have a same frequency; and apply a first drive signal to a first drive line of a plurality of drive lines during a first time period; and apply a second drive signal to a second drive line of the plurality of drive lines during a second time period, the second time period at least partially overlapping the first time period during an overlapping time period, wherein the first and second drive signals have a same frequency; and sense circuitry configured to: detect a sense signal from at least one sense line, the sense signal being related to the first and second drive signals by capacitive coupling and affected by touch or proximity of one or more objects to one or more sensing points associated with the at least one sense line, a sensing point being associated with at least one of the plurality of drive lines and at least one of a plurality of sense lines; and derive touch information for the one or more sensing points from the sense signal; detect a sense signal from at least one sense line, the sense signal being related to the first and second drive signals by capacitive coupling and affected by touch or proximity of one or more objects to one or more sensing points associated with the at least one sense line, a sensing point being associated with at least one of the plurality of drive lines and at least one of a plurality of sense lines; and derive touch information for the one or more sensing points from the sense signal; characterised in that the first and second drive signals are in phase during a first portion of the overlapping time period and out of phase during a second portion of the overlapping time period.
