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 2-dimensional (2D)/3-dimensional (3D) image display device generates 2D or 3D image data according to an input image signal and displays them on a display unit. The display unit includes a display panel for displaying an image in response to the 2D or 3D image data and an optical element layer operative during first and second driving modes in accordance with the 3D and 2D image data. A controller converts the optical element layer to be in the first driving mode in a first period before a 3D image signal is displayed when the input image signal changes from a 2D image signal to the 3D image signal, and converts the optical element layer to be in the second driving mode in a second period after the 2D image signal is displayed when the input image signal changes from the 3D image signal to the 2D image signal.

Abstract: A display device includes a display panel including a first partial panel region and a second partial panel region, and a panel driver which drives the display panel. The panel driver determines a first driving frequency for the first partial panel region and a second driving frequency for the second partial panel region. In a case where the first driving frequency and the second driving frequency are different from each other, the panel driver sets a boundary portion including a boundary between the first partial panel region and the second partial panel region, and determines a third driving frequency for the boundary portion to be between the first driving frequency and the second driving frequency.
