Display apparatus and display method thereof

摘要

A display apparatus and a display method thereof are provided. The display apparatus includes a display panel, a timing controller, a data driving unit and an extending driving unit. The display includes a plurality of first pixels disposed in a frame display region and a plurality of second pixels disposed in an extending display region, where the extending display region surrounds the frame display region. The timing controller outputs a plurality of display data corresponding to a display frame. The data driving unit outputs a plurality of first signals to the first pixels according to the display data. The extending driving unit obtains a display reference data corresponding to the display frame through the data driving unit, and provides a second driving signal to the second pixels according to the display reference data so as to determine the display effect of the second pixels.
