Abstract: A display device includes a housing, a flexible display panel, a light receiving sensor, and an area calculator. The flexible display panel is coupled to the housing and displays a reference image and an output image. The flexible display panel has an exposed area with a size that varies with movement of the flexible display panel in a first direction relative to the housing. The sensor senses the reference image and generates sensing data based on the reference image. The area calculator calculates the exposed area of the flexible display panel based on the sensing data.

Abstract: A display apparatus includes a display panel and a variable resistance area. The display panel includes a foldable area, a non-foldable area, and a folding axis. The variable resistance area may overlap the foldable area and includes a first resistance part and a second resistance part. The first resistance part has a first resistance when the display panel is folded with a curvature greater than a first curvature and a second resistance different from the first resistance when the display panel is folded with a curvature less than the first curvature. The second resistance part has a third resistance when the display panel is folded with a curvature greater than a second curvature and a fourth resistance different from the third resistance when the display panel is folded with a curvature less than the second curvature. The second curvature may be greater than the first curvature.
