A display device including a display panel having a first area, a second area, and a plurality of pixels to provide an image during a frame period, and a touch panel including a first touch part including first and second touch coils insulated from each other, and a second touch part including first touch electrodes and second touch electrodes insulated each other, in which corresponding second scan signals are applied to the first touch electrodes disposed in the first area when corresponding first scan signals are applied to the first touch coils disposed in the second area during a first period of the frame period, the second touch coils are configured to provide first sensing signals according to a resonant frequency of an input device, and the second touch electrodes are configured to provide second sensing signals according to a variation in a capacitance.

Display device and method of driving the same in two modes

A display device includes a display substrate comprising a polymer layer including a first non-bending area, a second non-bending area that overlaps the first non-bending area when viewed in a plan view, and a bending area arranged between the first non-bending area and the second non-bending area. A display element layer is disposed on the polymer layer. A plurality of signal pad groups is disposed in the second non-bending area and is configured to be electrically connected to the display element layer. An upper substrate is disposed on a top surface of the display substrate. A flexible circuit board comprising a plurality of connection pad groups is arranged in correspondence to the signal pad groups. An area of the upper substrate is larger than an area of the display substrate when viewed in a plan view.

Display device and manufacturing method for the same

A display device includes a display panel and a touch panel. The touch panel calculates coordinate information of an input position by an electrostatic capacitive method in a first mode and calculates the coordinate information of the input position by an electromagnetic induction method in a second mode. The touch panel includes scan line groups and source line groups, which are operated as touch electrodes or touch coils on the basis of the operating mode thereof. In addition, the touch panel includes touch electrodes and touch coils, which are individually operated on the basis of the operating mode thereof.

A display device includes a display panel which displays an image; a mold frame including: a horizontal portion on which an edge of a back surface of the display panel is supported; and a vertical portion extending from the horizontal portion in a direction away from the display panel; an adhesive member between the horizontal portion of the mold frame and the back surface of the display panel; and a curable adhesive member between the horizontal portion of the mold frame and the back surface of the display panel, where the curable adhesive member is disposed spaced apart from the adhesive member along the horizontal portion of the mold frame to be disposed closer to the vertical portion of the mold frame than the adhesive member.
