Abstract:
A display device includes a first pixel driver connected to a sweep line, the first pixel driver generating a control current based on a first data voltage, a second pixel driver connected to a scan control line, the second pixel driver generating a driving current based on a second data voltage and controlling a period for which the driving current flows, based on the control current, and a light-emitting element connected to the second pixel driver to receive the driving current. The first pixel driver includes a first transistor generating the control current based on the first data voltage, a second transistor providing the first data voltage to a first electrode of the first transistor based on a scan write signal, and a first capacitor including a first capacitor electrode connected to a gate electrode of the first transistor, and a second capacitor electrode connected to the sweep line.
