1. A display apparatus comprising:
a display panel comprising a plurality of rows of scan lines and a plurality of columns of data lines, the plurality of rows of scan lines and the plurality of columns of data lines defining a plurality of sub-pixel regions, a first view pixel and a second view pixel being provided in each of the sub-pixel regions; and
a view control device connected with the display panel, the view control device configured to: identify a number of users on a user side of the display panel; and control a driving voltage of the scan lines according to the number of the users, so that the display panel controls the first view pixel and the second view pixel according to the driving voltage so as to display a first view mode or a second view mode,
wherein a visual angle in the first view mode is greater than a visual angle in the second view mode;
wherein a first switch unit and a second switch unit are further provided in each of the sub-pixel regions;
wherein the first view pixel is respectively connected with one of the scan lines and one of the data lines through the first switch unit, the second view pixel is respectively connected with one of the scan lines and one of the data lines through the second switch unit, and the first switch unit and the second switch unit in a same one of the sub-pixel regions are connected with a same one of the scan lines and a same one of the data lines;
wherein the first switch unit and the second switch unit are both thin film transistors; and
wherein a threshold voltage of the first switch unit is greater than a threshold voltage of the second switch unit, so that the display panel controls the first view pixel and the second view pixel according to a relationship between the driving voltage and the threshold voltage of the first switch unit and a relationship between the driving voltage and the threshold voltage of the second switch unit.
