Abstract
A sensing circuit discharge control method and device for a touch panel are disclosed. A discharging duration of a current source in the sensing circuit of the touch panel is fine tuned in a digital control manner, so as to control the discharging amount of the sensing circuit without frequently adjusting the discharging current of the current source. By using the present invention, discharging time difference between a condition in which a touch event occurs and a condition in which no touch event occurs for each sensing circuit can approach the same.
