    Abstract: 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.

    Abstract: A touch member for a display device includes first and second touch signal lines and an insulating layer between first and second conductive layers. The first touch signal line includes a first sub-touch signal line corresponding to the first conductive layer, and a second sub-touch signal line corresponding to the second conductive layer and connected to the first sub-touch signal line through first and second contact holes penetrating the insulating layer. The second touch signal line includes a third sub-touch signal line corresponding to the first conductive layer, and a fourth sub-touch signal line corresponding to the second conductive layer and connected to the third sub-touch signal line through third and fourth contact holes penetrating the insulating layer. The first and second contact holes are spaced by a first distance, and the third and fourth contact holes are spaced by a second distance less than the first distance.

    Abstract: A display device is described including a display panel for displaying an image and an input sensing unit disposed on the display panel for sensing a user input. The input sensing unit includes: an electrode unit including first electrodes and second electrodes which intersect each other and a control unit for determining the proximity of an object or the shape of the object, based on capacitance change values of the first electrodes and the second electrodes. In a first mode the input sensing unit is driven using a self-capacitance method. The control unit may merge the capacitance change values, and determine the proximity of the object based on the merged value. In a second mode based on mutual capacitance, the control unit may determine the shape of the object.
