Abstract: A device and method for detecting touch delay time are disclosed. In one aspect, the device includes an event driver and a delay time measurement module. The event driver is configured to receive an interrupt signal generated by a touch on a touch screen panel, process a first system count value at a time when the interrupt signal is received as an interrupt generation time, and schedule a task corresponding to the interrupt signal. The delay time measurement module is configured to process a second system count value at a time when a task execution signal is transmitted to an application module as an application execution time, and calculate the touch delay time based on the difference between the interrupt generation time and the application execution time.
