    Abstract: According to an aspect, a display device includes: a substrate that has a display area; pixels that are provided in the display area and are arranged in a first direction and a second direction intersecting the first direction; gate lines that extend in the first direction and are arranged in the second direction; and a first gate driver and a second gate driver that are configured to supply gate drive signals to the gate lines. The first and second gate drivers are each provided along the second direction and are arranged in the first direction. The first and second gate drivers are configured to: sequentially scan the gate lines in a first area of the display area; and simultaneously scan more than one of the gate lines that are adjacent to one another in the second direction in a second area different from the first area of the display area.

    CPC classification number: H04N13/312

    Abstract: A display device includes: a display panel with pixels; a light source with light emission points; an acquirer configured to acquire viewpoint information; and a controller configured to control image display based on the viewpoint information on positions of viewpoints and an arrangement direction of the viewpoints. The controller is configured to drive some or all of pixels positioned on straight lines each connecting a corresponding one of the light emission points to a corresponding one of the viewpoints based on a relative rotation angle between the display panel and the arrangement direction and a relative positional relation between the viewpoints and the light emission points. The light emission points are individually switchable between a turned-on state and a turned-off state. A pitch of the light emission points is smaller than a pitch of light emission points controlled to be turned on when outputting an individual image to each viewpoint.

    Abstract: According to one embodiment, an electronic device includes a display panel configured to display an image and including a display region that transmits external light, a light source unit, a camera opposed to the display region of the display panel, and a control unit. The control unit is configured to in a light emission period, permit irradiation of light by the light source unit, irradiate the display region with light, display the image in the display region, and prohibit capturing by the camera. The control unit is configured to in a capturing period, prohibit the irradiation of the light by the light source unit, set the display region to be transparent, permit the capturing by the camera, and take in the external light transmitted through the display region to the camera.

    IPC: G09G3/36

    Abstract: According to one embodiment, a display device includes a display panel on which first pixels and second pixels are alternately arranged in the columnar direction, and a display controller configured to input a first image signal and to display an image. The first pixels and the second pixels are arranged such that first sub-pixels are adjacent to third sub-pixels in the columnar direction. The display controller is configured to execute conversion of converting the input first image signal into a second image signal, vary the luminance values of the third sub-pixels in the second image signal based on the luminance values of the third sub-pixels in the first image signal which become unable to be represented in the display panel.

    IPC: G09G3/32

    Abstract: According to an aspect, a display device includes a pixel including a first sub-pixel configured to emit light having a peak in a spectrum of red, a second sub-pixel configured to emit light having a peak in a spectrum of green, and a third sub-pixel configured to emit light having a peak in a spectrum of blue. The first sub-pixel, the second sub-pixel, and the third sub-pixel are inorganic light-emitting diodes. A light emission intensity of the second sub-pixel is increased at a predetermined ratio with respect to a light emission intensity of the first sub-pixel when the first sub-pixel emits light at a light emission intensity within a low-luminance range equal to or lower than a predetermined level of luminance.

    Abstract: According to an aspect, a display device includes: a display unit including a plurality of pixels; and an image processor configured to generate an image signal for displaying an image on the display unit. When the image processor causes the display unit to display the image such that a first pixel region that displays a first color is adjacent to a second pixel region that displays a second color and that has luminance higher than luminance of the first color, the image processor applies gain to an image signal corresponding to a pixel in the second pixel region to make brightness of the second pixel region lower than brightness of the first pixel region.
