    Abstract: A pixel circuit includes a light-emitting device, a reset circuit, a write circuit, a compensation circuit, a light emission control circuit, and a drive circuit. The compensation circuit is configured to selectively transfer an uncompensated reference voltage or a compensated reference voltage to a third node, the compensated reference voltage being determined by the uncompensated reference voltage and a compensation voltage, the compensation voltage being related to a rated value of a power supply voltage. The light emission control circuit is configured to transfer a voltage at the third node to a first node to cause a change in voltage at the second node. The drive circuit is configured to control a magnitude of a drive current flowing through the light-emitting device based on the voltage at the second node and the power supply voltage.

    Abstract: The present application discloses an electronic device including a housing, support plates and a display panel. The housing is recessed inward to form one or more clearances penetrating the housing along a first direction. A number of the support plates is at least two, and one clearance is correspondingly arranged below adjoining parts of two adjacent support plates. The support plates are configured to support the display panel. The display panel is switchable between a folded position and an unfolded position. When the display panel is in the unfolded position, first surfaces of the support plates that abut against the display panel are flush. When the display panel is in the folded position, any two oppositely folded and adjacent support plates are separated by a part of the display panel that covers the any two oppositely folded and adjacent support plates when the display panel is in the unfolded position, and a part of the any two oppositely folded and adjacent support plates and a part of the display panel that covers the part of the any two oppositely folded and adjacent support plates when the display panel is in the unfolded position enter the clearance.

    Abstract: Embodiments of this disclosure provide a flexible display device. The flexible display device comprises a flexible display panel and a folding mechanism. The folding mechanism comprises a first cabinet and a second cabinet overlapping each other, and a guiding mechanism. The second cabinet can move straight relative to the first cabinet through the guiding mechanism. The flexible display device further comprises a guiding portion and an adjusting lever in the second cabinet. The guiding portion is at a push-pull end of the second cabinet. The adjusting lever can move between the push-pull end and an end opposite to the push-pull end. One end of the flexible display panel is fixed to the push-pull end of the first cabinet, and the other end is fixed to the adjusting lever in an opposite direction. A locking mechanism fixes relative positions of the first cabinet, the second cabinet and the adjusting lever.
