Abstract: A touch sensor includes first touch cells disposed in a first touch sensing area, the first touch cells each including a first touch pattern and a first dummy pattern, and second touch cells disposed in a second touch sensing area, the second touch cells each including a second touch pattern and a second dummy pattern. An area of a first dummy pattern area in which the first dummy pattern is disposed is greater than an area of a second dummy pattern area in which the second dummy pattern is disposed.

Abstract: A display device including: pixels; a data driver configured to start outputting data voltages to at least some of the pixels at a first time during a horizontal period, and end outputting the data voltages at a second time during the horizontal period; sensors; and a sensor driver configured to change a logic level of a sensing signal of at least some of the sensors at a third time different from the first time and the second time during the horizontal period, wherein at least one of the first time, the second time, and the third time is changed according to a number of times a logic level of a vertical synchronization signal is changed while a logic level of a horizontal synchronization signal is maintained.
