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.

Abstract: In a scan lines driver that is used for driving scan lines of an organic light emitting diodes (OLED) display, a large voltage drop can develop between the gate or source of one of its transistors and the corresponding drain during a scan signal outputting period. This large voltage drop can excessively stress the one transistor. However, in accordance with the present disclosure, a voltage drop dissipating, second transistor is provided in series with the first transistor for absorbing part of the large voltage drop and thus reducing the stress that is applied to the first transistor.
