摘要： A touch detection module includes driving electrodes extending parallel to each other, sensing electrodes crossing the driving electrodes, and a touch driver circuit for supplying touch driving signals to the driving electrodes and for detecting touch sensing signals through the sensing electrodes to determine touch position coordinates. The touch driver circuit selects between a group driving scheme and a sequential driving scheme for at least one frame. According to the group driving scheme, the touch driver circuit sorts the driving electrodes into groups, simultaneously drives driving electrodes in a same group among the groups, and drives the groups at different times. According to the sequential driving scheme, the touch driving circuit sequentially drives the driving electrodes.

摘要： A display device includes a substrate. A plurality of sensing electrodes is on the substrate. A first touch insulating layer is disposed above the plurality of sensing electrodes. A plurality of driving electrodes is disposed on an upper surface of the first touch insulating layer. The plurality of driving electrodes receives a touch driving signal. A touch driving circuit sensing a change amount of mutual capacitance is formed between the plurality of driving electrodes and the plurality of sensing electrodes by the plurality of sensing electrodes. The first touch insulating layer includes an organic material.

摘要： 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.
