    Abstract: The present disclosure provides a pixel circuit, a pixel driving method, and a display device. The pixel circuit includes a driving transistor, a threshold compensation sub-circuit, and a light emission control sub-circuit. The threshold compensation sub-circuit is configured to write a reset voltage to the control terminal of the driving transistor in a reset phase under the control of the first, second and third control signal terminal, and write a control voltage to the control terminal of the driving transistor in a data writing phase. The driving transistor is configured to generate a driving current according to the control voltage in a light emitting phase. The light emission control sub-circuit is configured to output the driving current to the light emitting device in the light emission phase under the control of the light emission control signal terminal to drive the light emitting device to emit light.

    Abstract: A fingerprint identification module and a display device are disclosed. In the fingerprint identification module, a light shading layer above a photosensitive sensing unit includes a first light shading component above a photosensitive diode of the photosensitive sensing unit, and a fixed potential signal line. The first light shading component is electrically connected to a terminal of the photosensitive diode thereunder and connected to the fixed potential signal line. Since the fixed potential signal line is above the photosensitive diode, and the light shading layer is directly used to form the fixed potential signal line, connecting holes that need to occupy some space can be omitted, and the area occupied by the photosensitive diode can be maximized, thus the light current generated by the photosensitive diode during fingerprint detection can be increased so as to enhance fingerprint detection accuracy.

    Abstract: The embodiments of the present disclosure provide an array substrate. The array substrate includes a plurality of pixel groups arranged along a column direction. Each of the plurality of pixel groups includes a plurality of sub-pixel rows. Each sub-pixel row includes a plurality of sub-pixels, a first shelter or a second shelter is arranged between two adjacent sub-pixels, and the first shelter and the second shelter are arranged alternately. The first shelter has a first width, and the second shelter has a second width. For each pixel group, the first shelters on at least one of the sub-pixel rows are aligned with the second shelters on at least one of other sub-pixel rows.
