    摘要： A display device includes a display panel configured to display an image on a front surface thereof, and a flexible circuit board connected to the display panel and configured to drive the display panel. The display device further includes a pressure sensor including a first electrode and a second electrode. The pressure sensor is configured to sense a change of capacitance of a capacitor, which is formed between the first electrode and the second electrode, in accordance with a pressure applied thereto. The flexible circuit board includes a first surface and a second surface facing the first surface. The first electrode and the second electrode are disposed on the first surface or the second surface.

    摘要： 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.

    摘要： 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.
