Abstract: Disclosed by the embodiment of the present disclosure is a display device, wherein a collimation structure is formed by a first imaging aperture in a pixel defining layer and a second imaging aperture in a light shielding layer, the first imaging aperture and the second imaging aperture may screen out light rays reflected by a fingerprint in a nearly collimated manner so that the light rays may reach a fingerprint recognition component below, the fingerprint recognition component may detect and read intensities of the light rays, and the intensities of the light rays detected by the fingerprint recognition component are different because of different energies of the light rays transmitted downward from the valley and the ridge of the fingerprint, thereby acquiring fingerprint information and achieving fingerprint recognition. Moreover, the fingerprint recognition component is integrated in a display area to achieve large-area fingerprint recognition.

Abstract: A display substrate, a manufacturing method thereof and a display device are provided. The display substrate includes: a driver circuit layer, a planarization layer and light-emitting units, each light-emitting unit includes an anode, a cathode and an organic light emitting layer located between the anode and the cathode, and the anode is connected to a driving electrode of the driver circuit layer through a via hole in the planarization layer. The organic light emitting layer includes: at least one pixel repetition unit, each pixel repetition unit includes multiple pixels, and each pixel includes multiple sub-pixels with different colors. Via holes in the planarization layer that correspond to same colored sub-pixels of at least two pixels in the same pixel repetition unit have different via hole positions, the via hole position being a relative position of a projection of a via hole in the planarization layer within corresponding sub-pixel.

Abstract: The present disclosure provides flexible display device and a support device thereof. The support device includes a skeleton chain which includes a plurality of connected skeleton units. Each skeleton unit includes a head portion and a tail portion joined to the head portion. The head portion has a first rotary surface. The first rotary surface is a cylindrical curved surface or a spherical surface. The tail portion includes a cavity which has a second rotary surface. A radius of the first rotary surface is larger than that of the second rotary surface of the adjacent skeleton unit. The second rotary surface enwraps a part of the first rotary surface of the adjacent skeleton unit such that the head portion of the adjacent skeleton unit engages with the cavity of the tail portion and is rotatable with respect to the cavity of the tail portion.
