Abstract: According to an aspect, a display device includes a display panel comprising a plurality of pixels, a light guide plate, a light source configured to emit light from a lateral side of the light guide plate, a dimming panel, and a controller. The dimming panel comprises a plurality of dimming areas arranged in an emission direction of the light from the light source. The dimming areas are capable of individually changing transmittance of the light according to intensities of light required to display an image using the display panel. When adjacent two of the dimming areas differ in light transmittance from each other, the controller increases output gradation values of target pixels, the target pixels being located in a predetermined area extending from a boundary between the two dimming areas in one of the two dimming areas that has lower light transmittance.

Abstract: The reliability of a display device with an input device is improved. A plurality of detection electrodes (input position detection electrodes) forming an electrostatic capacity between them and a common electrode of a display device to detect an input position are formed on a different substrate from substrates configuring the display device. Moreover, a polarizing plate and the substrate on which the plurality of detection electrodes are formed are adhesively fixed via, for example, an adhesive layer so that the plurality of detection electrodes are fixed so as to be separated apart from the display device. Thus, a distance between electrodes (the detection electrode and a driving electrode) for detecting an input position can be set separately from a thickness of the display device, and therefore, reduction in detection sensitivity (detection reliability) for the input position due to increase in the electrostatic capacity can be suppressed.

Abstract: A display system includes an imaging apparatus installed on a mobile body; a display apparatus installed at a position different from that of the imaging apparatus on the mobile body and displaying a post-processing image; a first sensor detecting vibration at or near the imaging apparatus; a second sensor detecting vibration at or near the display apparatus; a first image processor clipping out a preprocessing image from an image captured by the imaging apparatus, based on the first sensor detection result; and a second image processor clipping out the post-processing image from the preprocessing image based on the second sensor detection result. The first image processor moves a clip-out region of the preprocessing image in a direction to counteract vibration at or near the imaging apparatus, and the second image processor causes a clip-out region of the post-processing image to follow vibration at or near the display apparatus.
