<p>An apparatus for measuring touch delay time includes: an event driver that receives an interrupt signal, generated by touch in a touch screen panel, records a system count value, as an interrupt occurrence time point, at a time point when the interrupt signal is received, and executes scheduling to firstly perform a task corresponding to the interrupt signal; and a delay time measurement unit that records a system count value, as an application execution time point, at a time point when a task execution signal for commanding execution of the task is transmitted to an application, and calculates the touch delay time of the touch screen panel by deducting the interrupt occurrence time point from the application execution time point.</p> |
