METHOD AND APPARATUS COMPENSATING PARASITIC CAPACITANCE IN TOUCH PANEL

摘要

A touch controller and touch display device incorporating same are described. The touch controller includes a parasitic capacitance compensation unit that receives a common electrode voltage to generate a quantity of charge capable of compensating for a quantity of charge associated with a parasitic capacitance between a sensing channel and a common electrode in a touch panel capable of capacitive sensing of a touch input.
