    Abstract: An electronic apparatus includes a display panel and a digitizer disposed under the display panel and provided with a plurality of holes defined therethrough to overlap the folding region. The digitizer includes a first base layer, first loop coils including first first coils and second first coils, a second base layer disposed under the first base layer, second loop coils including first second coils and second second coils, and interposed between the first base layer and the second base layer, and bridge patterns. A first first line included in one bridge pattern is connected to a corresponding first first coil, and a second first line included in the bridge pattern is connected to the second first coil which receives a signal the same as a signal of the first first coil.

    Abstract: A display module includes a display panel and an input sensing unit. The display panel includes a base surface. The input sensing unit is directly disposed on the base surface. The input sensing unit includes a first electrode, a second electrode, and an insulation layer. The first electrode extends in a first direction. The first electrode includes a first opening area. The second electrode extends in a second direction intersecting the first direction. The second electrode is longer than the first electrode. The second electrode includes a second opening area of a size greater than a size of the first opening area. The insulation layer is configured to insulate the first electrode from the second electrode.
