Abstract: Disclosed is a display apparatus. The display apparatus includes: display modules, each of which includes: a display panel composed of inorganic light emitting elements arranged in row lines, and sub-pixel circuits respectively corresponding to the inorganic light emitting elements; and a driver configured to drive the sub-pixel circuits in an order of the row lines based on a start signal provided from a timing controller. The timing controller is configured to: provide a first start signal to the driver of a first display module to control the inorganic light emitting elements to sequentially emit light from a first row line to a last row line, and provide a second start signal to the driver of a second display module to control the inorganic light emitting elements to sequentially emit light following an emission order of the inorganic light emitting elements included in the last row line of the first display module.
