    Abstract: A quantum dot color filter substrate, a display panel, and a display device are provided. The quantum dot color filter substrate includes a plurality of pixel units arranged in an array. The pixel unit includes a blue sub-pixel, a red sub-pixel, and a green sub-pixel. The red sub-pixel includes a red quantum dot color filter. The green sub-pixel includes a green quantum dot color filter. An area ratio of the blue sub-pixel, the red sub-pixel, and the green sub-pixel is 1:X:Y, and 2.5≤X≤5, 4≤Y≤6. The quantum dot color filter substrate is used for cooperating with a blue backlight, and for compensating the difference in the conversion efficiency of the blue dot color filter with different colors for the blue light, and improving the color shift phenomenon caused by the difference in the conversion efficiency of the blue dot color filter with different colors to blue light.

    Abstract: A foldable display device includes a flexible display screen, a foldable assembly and a non-display function assembly. The states of the foldable display device include an unfolded state and a folded state. In the unfolded state, a first support plate and a second support plate are disposed on two opposite sides of a connector respectively, and the flexible display screen covers the first support plate, the connector, the second support plate and the non-display function assembly. In the folded state, a first part and a second part of the flexible display screen overlap, the first support plate and the second support plate overlap and are disposed between the first part and the second part. A part of the flexible display screen on the side of the second support plate which is away from the first support plate does not cover the non-display function assembly.

    Abstract: Disclosed are a display panel, a driving method thereof and a display device. The display panel includes: a light-shielding layer including imaging apertures, a light-emitting element layer including first light-emitting elements and second light-emitting elements, a touch functional layer, and a fingerprint recognition module. The orthographic projection of the second light-emitting element on the light-shielding layer is closer to the corresponding imaging aperture than the orthographic projection of the first light-emitting element on the light-shielding layer. In a first detection stage, the first light-emitting elements emit light, the second light-emitting elements do not emit light, and the fingerprint recognition module generates a first fingerprint image. In a second detection stage, the second light-emitting elements emit light, and the fingerprint recognition module generates a second fingerprint image. The first fingerprint image and the second fingerprint image are combined into a fingerprint image.

    Abstract: A backlight drive method, a backlight drive device, a backlight source system, and a display device are provided in the present disclosure. The backlight drive method is used to drive a light-emitting region of a backlight source of the display device. Driving the light-emitting region of the backlight source includes acquiring actual ambient brightness of an ambient where the display device is located. Driving the light-emitting region of the backlight source further includes determining a target backlight brightness range of light exited from the light-emitting region with reference to the actual ambient brightness, where the target backlight brightness range is within an intrinsic brightness range of the light-emitting region. Driving the light-emitting region of the backlight source further includes matching the target backlight brightness range to a plurality of gray levels preset in the light-emitting region.

    Abstract: A method for driving a display panel and a display apparatus are provided. The display panel includes a display region including a fingerprint recognition region and includes subpixels located in the display region, and the subpixels include first subpixels located in the fingerprint recognition region and used as a light source for fingerprint recognition. In a first mode, the subpixels are scanned at a first frequency, and in the second mode, the subpixels are scanned at a second frequency. The second frequency is greater than the first frequency. The method includes: when the display panel is in the first mode, monitoring whether the display panel receives a fingerprint recognition requirement, and if yes, controlling the display panel to enter a trigger state; and when the display panel is in the trigger state, scanning the first subpixels at a frequency greater than the first frequency.
