Abstract: Provided are a pixel and a display apparatus including the same. The pixel includes a driving circuit connected to a gate line and a data line and including a driving transistor, a light-emitting diode connected to the driving circuit, and an initialization circuit connected between an initialization voltage line and a node to which the driving circuit and the light-emitting diode are connected. The initialization circuit is configured to transmit a second initialization voltage, obtained by subtracting a certain voltage from a first initialization voltage supplied through the initialization voltage line, to the node.

Abstract: A pixel includes a light emitting element, a driving transistor configured to control a driving current provided to the light emitting element, and an initialization transistor configured to provide a first initialization voltage to a gate of the driving transistor, and turned on in response to an initialization gate signal. A voltage level of the first initialization voltage in a blank period of a low-frequency driving mode is higher than a voltage level of the first initialization voltage in the blank period of a high-frequency driving mode.
