Abstract
Disclosed herein are a display device having an embedded touch screen and a method for detecting a touch, and more particularly, a display device having an embedded touch screen capable of preventing deterioration of image quality generated in the display device when a touch sensor and a sensor signal line are disposed in the display device and solving a problem that sensitivity of a detected touch signal is weakened due to a parasitic capacitance generated between the touch sensor and the sensor signal line and a signal line and components of the display device, and a method for detecting a touch.
