1. A display module comprising:
a display panel comprising a plurality of pixels each comprising a plurality of sub pixels, the plurality of pixels being disposed on row lines of the display panel, and each of the plurality of sub pixels including an inorganic light emitting element; and
a driver configured to be electrically connected to the display panel, and to drive the display panel,
wherein the driver is further configured to:
sequentially apply a pulse width modulation (PWM) data voltage to the sub pixels of the display panel in an order of the row lines during one image frame time; and
drive the display panel such that inorganic light emitting elements of sub pixels included in at least two consecutive row lines among the row lines emit light multiple times based on the applied PWM data voltage during the one image frame time,
wherein the inorganic light emitting elements of sub pixels included in the at least two consecutive row lines sequentially emit light in an order of the at least two consecutive row lines, and
wherein the driver is further configured to drive the display panel such that the inorganic light emitting elements of the sub pixels included in each of the at least two consecutive row lines emit light for a time corresponding to the applied PWM data-voltage voltage, and
wherein the driver is further configured to:
apply the PWM data voltage to sub pixels included in each of the row lines during a data setting period for each of the row lines; and
drive the display panel such that the inorganic light emitting elements of the sub pixels included in each of the at least two consecutive row lines emit light for the time corresponding to the applied PWM data voltage within each of a plurality of light emission periods for each of the at least two consecutive row lines.
