Abstract: An emission driver, organic light-emitting diode (OLED) display including the same, and electronic device are disclosed. In one aspect, the emission driver includes first through (n)th emission circuits configured to output a plurality of emission control signals. The emission circuits are connected to a display panel of an OLED display via emission-lines. The emission driver also includes a plurality of first switches configured to electrically connect the emission circuits in series when the first switches are turned on and a plurality of second switches configured to electrically connect the emission circuits in parallel when the second switches are turned on. The second switches are further configured to be turned off when the first switches are turned on and the second switches are further configured to be turned on when the first switches are turned off.
