Abstract
An electronic device having a touch sensor and a method of driving the same are disclosed. The electronic device includes a display panel having a touch screen, a touch driver configured to drive the touch screen, a timing controller configured to control the display panel and the touch driver, and a stylus pen configured to provide a signal to the touch screen. The timing controller, in order to synchronize with the stylus pen, generates and outputs a control signal having an extended vertical blanking period in which a vertical blanking period is extended, and a display driving period and a touch sensor driving period which alternate in two or more times for one frame.
