Abstract: According to one embodiment, an imaging display system includes an imaging device and a display device, which operate synchronously with each other. The imaging display system includes a control device. The control device is configured to measure light exposure when the imaging device captures an image and determine whether the measured light exposure is insufficient, and control the display device to decrease a refresh rate and the imaging device to prolong an exposure time, when determined that the light exposure is insufficient. The first scanning time for the imaging device to scan the image and the second scanning time required for the display device to scan the display panel are constant.

Abstract: An input device includes a first substrate, a light-emitting element unit, and third conductive layers. The first substrate includes first and second surfaces. The light-emitting element unit includes: first conductive layers formed in one layer on the second surface side; second conductive layers formed in one layer on the second surface side different from the layer of the first conductive layers; and a luminescent layer provided between the first and the second conductive layers and electrically in contact therewith. The third conductive layers are formed to be insulated from the first and the second conductive layers and not to intersect with the second conductive layers in planar view, and are configured to detect a change in an electric field between the first and the third conductive layers depending on coordinates of a proximity object at a position overlapping with the first conductive layers and the first surface in planar view.
