Display device gradually decreasing initialization voltage when converting driving frequency to low frequency

Abstract

A display device includes: a light emitting element including an anode and a cathode; a first transistor connected to the anode and a power line, and switchable by a voltage of a first node; a second transistor connected to a data line and a second node, and switchable by a write scan signal; a capacitor connected to the first node and the second node; an initialization transistor connected to the anode and an initialization line configured to receive an initialization voltage, and switchable by a bias scan signal, where the write scan signal is applied to the second transistor at a first frequency and a second frequency lower than the first frequency. When converting from the first frequency to the second frequency, in a k-th frame of the second frequency, a level of the initialization voltage may gradually decrease.
