Abstract: A display apparatus includes: a display; a display driver that drives the display such that the display displays in accordance with display data; and a host controller that transfers update display data of one screen to the display driver. The display driver includes a light-emission controller that causes a self-luminous elements to emit light, and a memory that stores the update display data of the one screen. The display driver reads the update display data on the memory after an elapse of a predetermined period of time from a drive end time at which the display controller finishes driving in accordance with the update display data and drives the screen by using the read update display data. The display driver drives the self-luminous elements once or more at a timing when the update display data from the host controller to the display driver is not updated.

Abstract: A host control unit is configured to set a transition interval between a first period for which an image is displayed at a first frame rate and a second period for which the image is displayed at a second frame rate different from the first frame rate, the transition interval being a period in which a frame rate is changed between the first frame rate and the second frame rate, and cause a display control unit to reduce a luminance difference of the image data in the transition interval, the luminance difference being caused when the frame rate is changed between the first frame rate and the second frame rate.

Abstract: A display device includes: a display unit; a display driver configured to drive the display unit; and a display-data generator configured to transfer a screenful of update display data to the display driver. The display driver includes a light-emission controller configured to control self-luminous elements to emit light, and a memory storing a screenful of the update display data. After a lapse of a predetermined time period from a driving stop time, the display driver reads the update display data stored in the memory and then uses the update display data to drive a screen, the driving stop time being a time when the display unit is stopped from driving based on the update display data. The display driver causes the self-luminous elements of the display unit to emit light, even during a display update or no display update performed on the display driver by the display-data generator.

Abstract: A control apparatus configured to control a display apparatus including a self-luminous element includes: an image judgment unit configured to determine whether or not a ratio of a number of pixels located in a predetermined area of an image and having gradation levels within a gradation range from a first gradation level not equal to a lowest gradation level to a second gradation level not equal to a highest gradation level is equal to or larger than a threshold value; and a drive change unit configured to determine a refresh rate of the display apparatus including the self-luminous element according to a result of the determination made by the image judgment unit. The image judgment unit is configured to determine at least one of (1) the value of the first gradation level and the value of the second gradation level, and (2) the threshold value.
