Abstract: An image display device includes a display unit that includes a plurality of display lines, an image data input unit that receives image data including data for each display line, and an image data transmission switching circuit that transmits the image data to the display unit.

Abstract: A display apparatus includes a sight line detection sensor that detects a sight line of a user; a distance measurement sensor that measures a distance between a display panel and a user; and a control unit that determines a control region set in separate light emitting parts arranged on the display panel, where an amount of light emission is controlled in the control region, based on the sight line detected by the sight line detection sensor and the distance measured by the distance measurement sensor. Typically, the control unit determines the control region in a manner such that the longer the distance measured by the distance measurement sensor, the smaller the control region, and the shorter the distance measured by the distance measurement sensor, the larger the control region.
