    摘要： 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.

    摘要： In a case where next image data, corresponding to a next screen, is not supplied from a host even when first predetermined time has elapsed since the first supply of image data was completed, the period control section (32) starts the second supply of the image data, of which the first supply has been carried out, to a liquid crystal display device. In a case where next image data, corresponding to a next frame, is not supplied from the host even when second predetermined time has elapsed since the second supply of the image data was completed, the period control section (32) starts the third supply of the image data to the liquid crystal display device, and sets the first predetermined time to be longer than the second predetermined time. This makes it possible to appropriately update a displayed image.

    摘要翻译： 即使在第一次图像数据的供给完成之后经过了第一预定时间的情况下，即使从下一个画面来的下一个图像数据也不从主机提供的情况下，周期控制部32开始第二次 将已经进行了第一次供给的图像数据提供给液晶显示装置。 即使在第二次图像数据的供给完成之后经过了第二预定时间的情况下，即使没有从主机提供对应于下一帧的下一个图像数据，周期控制部（32）开始第三次 将图像数据提供给液晶显示装置，并将第一预定时间设定为长于第二预定时间。 这使得可以适当地更新显示的图像。

    摘要： 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.
