摘要： A fingerprint identifying device and a fingerprint identifying system are provided. The fingerprint identifying device including: a substrate; a transparent cover plate, located right above the substrate; a detection light source, located on a first side of the transparent cover plate; and a photoelectric sensor, located on a side of a lower surface of the transparent cover plate, wherein, a refractive index of the transparent cover plate is less than a refractive index of a skin of a human fingerprint part, the transparent cover plate has a side surface on the first side, and an angle α between the side surface and an upper surface of the transparent cover plate is an acute angle, the detection light source is configured to provide a light beam towards the side surface of the transparent cover plate, so that the light beam is incident to the upper surface of the transparent cover plate through the side surface of the transparent cover plate, and the light beam is totally reflected on the upper surface of the transparent cover plate in a case that the upper surface of the transparent cover plate is in contact with air, the photoelectric sensor is configured to receive a light beam reflected from the upper surface of the transparent cover plate. The fingerprint identifying device is capable of improving the identifying accuracy thereof.

摘要： The present invention provides a 3D display device and a driving method thereof, and relates to a display technology field for solving a problem that a 3D picture crosstalk is large due to a low contrast between a bright grating unit and a dark grating unit in the grating. Wherein the 3D display device comprises a grating and a display panel, the grating is divided into a bright grating cell and a dark grating cell, the grating comprising a substrate and a plurality of OLED light-emitting devices arranged on the substrate, At least a part of the plurality of OLED light emitting devices emit light to apply the operating voltage to form the bright grating cells, and the non-light emitting OLED light-emitting devices form the dark grating cells. The 3D display device is for displaying a 3D picture.
