    Abstract: A flexible display device is provided, including: a flexible display panel; functional members on a first side of the flexible display panel; a back film on a second side of the flexible display panel; a supporting member on a side of the back film away from the flexible display panel; and adhesive layers. The flexible display device is switchable between unfolded and folded states, and the folded state includes inwardly and outwardly folded states. In the inwardly folded state, at least part of the flexible display device is bent in a first bending direction at a first radius of curvature, in the outwardly folded state, at least part of the flexible display device is bent in a second bending direction at a second radius of curvature, and the first radius of curvature is less than the second radius of curvature.

    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: Embodiments of the present disclosure provide a projector and a method of driving a projector. The projector includes an image source for generating an image light and a transmission and reflection element. The image light includes a bright-state region image light and a dark-state region image light. The transmission and reflection element includes transmission and reflection units. Each of the transmission and reflection units is configured to reflect the image light irradiated thereon when in a reflective state, and to transmit the image light irradiated thereon when in a transmissive state. The transmission and reflection element is configured to perform one of a transmission and a reflection on the bright-state region image light so that the bright-state region image light is projected and displayed, and perform the other on the dark-state region image light so that the dark-state region image light is not projected and displayed.
