Classification: CPC G  H | IPC G

Claim 0:
1. A display apparatus comprising:
a modular display panel comprising a plurality of display modules disposed in a matrix form;
a sensing unit;
a correction unit; and
a timing controller,
wherein each of the plurality of display modules comprises:
a display panel comprising a pixel array in which pixels respectively composed of a plurality of inorganic light emitting elements are arranged in a plurality of row lines, and sub-pixel circuits respectively corresponding to inorganic light emitting elements of the pixel array; and
a driver configured to drive the sub-pixel circuits in an order of the row lines based on a start signal provided from the timing controller so that the inorganic light emitting elements of the pixel array emit light in the order of the row lines based on an image data voltage,
wherein the sensing unit is configured to:
sense a current flowing in a driving transistor included in the sub-pixel circuits based on a specific voltage, and output sensing data corresponding to the sensed current,
the correction unit is configured to:
correct the image data voltage applied to the sub-pixel circuits based on the sensing data, and
the timing controller is configured to:
provide a first start signal to a driver of a first display module among the plurality of display modules so that the inorganic light emitting elements of the first display module sequentially emit light from a first row line to a last row line, and
provide a second start signal to a driver of a second display module so that the inorganic light emitting elements of the second display module disposed adjacent to a bottom of the first display module emit light in the order of the row lines following an emission order of the inorganic light emitting elements included in the last row line of the first display module.
