Publication number: 20240119894Abstract: 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.Type: ApplicationFiled: December 15, 2023Publication date: April 11, 2024Inventors: YUICHI SATO, KENJI MAEDA, SHINJI YAMAMOTO, TAKUYA OKAMOTO, FUMITAKA SEKI, MASAFUMI ITO, YOHICHI TAKAZANE
