Claim 0:
1. A display module comprising:
a display panel in which a plurality of pixels are disposed on a plurality of row lines, each of the pixels including a plurality of sub-pixels, and each of the plurality of sub-pixels comprising an inorganic light emitting diode and a sub-pixel circuit configured to drive the inorganic light emitting diode based on a plurality of first control signals, a plurality of second control signals and a sweep signal sweeping between two different voltages; and
a driver configured to:
set a pulse width modulation (PWM) data voltage for an image frame to sub-pixel circuits of the display panel in a row line sequence by applying the plurality of first control signals to to the sub-pixel circuits of the display panel in the row line sequence, and
drive the display panel such that inorganic light emitting diodes of the display panel emit light multiple times based on the PWM data voltage in the row line sequence, by applying the plurality of second control signals and the sweep signal to the sub-pixel circuits of the display panel multiple times in the row line sequence,
wherein the driver comprises:
a first driver circuit comprising a first plurality of transistors and configured to generate at least one of the plurality of first control signals; and
a second driver circuit comprising a second plurality of transistors and configured to generate the sweep signal and at least one second control signal of the plurality of second control signals, and

wherein the first driver circuit and the second driver circuit are provided for each of the plurality of row lines,
wherein the second driver circuit comprises:
a first circuit comprising two first series-connected transistors among the second plurality of transistors, and configured to generate the at least one second control signal; and
a second circuit electrically connected to the first circuit, and configured to generate the sweep signal based on the at least one second control signal generated in the first circuit,

wherein the first circuit further comprises a first output end to which the two first series-connected transistors are connected and which is configured to output the at least one second control signal to the sub-pixels included in the one row line, and
wherein the second circuit comprises a second transistor in which a gate terminal is connected to the first output end, among the second plurality of transistors.
