Abstract

A display apparatus and a control method for controlling a display apparatus are provided. The display apparatus includes: a display panel including multiple rows of scan lines and multiple columns of data lines, the scan lines and the data lines defining multiple sub-pixel regions, a first view pixel and a second view pixel being provided in each sub-pixel region; and a view control device connected with display panel, the view control device configured to: identify the number of users on a user side of display panel; and control a driving voltage of the scan lines according to the number of the users, so that the display panel controls first view pixel and second view pixel according to driving voltage so as to display a first view mode or a second view mode. A visual angle in the first view mode is greater than a visual angle in the second view mode.
