Abstract
A display driver comprises a touch controller configured to perform touch sensing on a display panel during a vertical sync period. A first field of the vertical sync period comprises a display period and a touch sensing period following the display period. A start timing of the touch sensing period is controlled by an internal clock signal. A first counter is configured to, responsive to completion of the touch sensing, start a counting operation in synchronization with the internal clock signal. Gate control signal generator circuitry is configured to control a gate driver that is configured to drive a plurality of gate lines of the display panel. A gate line that is to be driven first to a high level during a second field following the first field is driven to the high level responsive to a count value of the first counter during the first field.
