Abstract: The present disclosure relates to a pixel driving circuit for switching display resolution, a driving method thereof, and a display apparatus. The pixel driving circuit comprises: r first data lines and k second data lines, each of the first data lines has a first switch provided thereon, and is connected to at least one of the k second data lines through at least one second switch respectively, and the first switch and the second switch are connected to a signal control unit which is configured to control the first switch to be turned on and the second switch to be turned off when display is to be performed at a first resolution, and control the first switch to be turned off and the second switch to be turned on when display is to be performed at a second resolution.

Abstract: The present disclosure relates to a pixel driving circuit, a driving method thereof, and a display apparatus, to realize switch between resolutions of the display apparatus which is driven by the pixel driving circuit. The pixel driving circuit comprises: r first data lines and k second data lines, each of the first data lines has a first switch unit provided thereon, and is connected to q second data lines through a second switch unit, and the first switch unit and the second switch unit are connected to a signal control unit respectively; and the signal control unit is configured to control the first switch unit to be turned on and the second switch unit to be turned off when display is to be performed at a first resolution, and control the first switch unit to be turned off and the second switch unit to be turned on when display is to be performed at a second resolution, wherein the first resolution is greater than the second resolution.
