    IPC: G09G3/32

    Abstract: A pixel circuit includes a light emitting element, a driving switching element, a storage capacitor, a data voltage applying switching element and a first leakage compensation switching element. The driving switching element is configured to apply a driving current to the light emitting element. The storage capacitor is connected to a control electrode of the driving switching element. The data voltage applying switching element is configured to apply a data voltage to the storage capacitor. The first leakage compensation switching element is disposed between the storage capacitor and the data voltage applying switching element.

    Abstract: A display apparatus is disclosed that includes a substrate including a front display area and a corner display area extending from a corner of the front display area. A plurality of main light-emitting elements is arranged in the front display area and a plurality of main pixel circuits are connected to the plurality of main light-emitting elements, respectively. A plurality of corner light-emitting elements is arranged in the corner display area and a plurality of corner pixel circuits are connected to the plurality of corner light-emitting elements. Each of the plurality of main pixel circuits and the plurality of corner pixel circuits includes a boost capacitor, and a capacitance of the boost capacitor included in each of the plurality of corner pixel circuits gradually increases or decreases as the boost capacitor gets farther from the front display area.

    Abstract: Provided is a scan driver for applying a bias voltage comprising a kth stage that includes an inputter transmitting an input signal to a first node, a stress reliever disposed between the first node and a second node, a carry signal outputter receiving a high-power-supply voltage and a second clock signal and outputting the second clock signal, an output signal outputter receiving the high-power-supply voltage and a third clock signal and outputting the third clock signal, a maintainer transmitting the first clock signal to a third node, and a stabilizer applying a first low-power-supply voltage to the third node and the high-power-supply voltage to the first node. The first and second clock signals selectively toggle between the high-power-supply voltage and the first low-power-supply voltage, the third clock signal selectively toggles between the high-power-supply voltage and a second low-power-supply voltage, and the bias voltage is adjusted as the second low-power-supply voltage varies.
