Abstract: A display apparatus includes: a modular display panel including a plurality of display modules; and a timing controller. Each of the plurality of display modules includes: a display panel including a pixel array and subpixel circuits; and a driving unit which drives the subpixel circuits such that inorganic light-emitting elements in the pixel array successively emit light in a first order of multiple row lines or in a second order opposite to the first order. The timing controller provides the driving unit of a first display module with first control signals for causing the inorganic light-emitting elements of the first display module to emit light in the first order, and provides the driving unit of a second display module, which is positioned above or below the first display module, with second control signals for causing the inorganic light-emitting elements of the second display module to emit light in the second order.
