    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 digitizer includes a base layer including first and second non-folding areas and a folding area disposed between the first and second non-folding areas and foldable with respect to a folding axis extending in a first direction and a plurality of coils disposed on the base layer and including a first coil and a second coil closest to the first coil. Each of the first coil and the second coil includes a coil portion defining an open loop and a line portion extending from the coil portion. The coil portion or the line portion overlaps the folding area, and a distance between the coil portion of the first coil and the coil portion of the second coil or a distance between the line portion of the first coil and the line portion of the second coil, which overlap the folding area, is equal to or greater than about 100 micrometers.
