Abstract: An optical fingerprint detection apparatus and a display device are disclosed. The optical fingerprint detection apparatus includes: a light source; a touch panel including a first surface and a second surface, the first surface being provided with at least one touch area, the second surface being configured for receiving the light beam emitted from the light source and angled with respect to the first surface by an angle of less than 90 degrees; and a detection unit located outside of the side of the touch panel opposite to the first surface and configured for receiving the light beam reflected by the touch area and emitted from the touch panel and detecting an intensity distribution of the received light beam.

Abstract: Embodiments of the present disclosure disclose a three-dimensional display device and a driving method thereof. Under the three-dimensional display mode, a plurality of light emitting areas and a plurality of black areas arranged alternately in row direction and column direction are formed in the electroluminescent display panel, and the light emitting area comprises repeatedly arranged R light emitting areas, G light emitting areas, B light emitting areas and X light emitting areas. Under the three-dimensional display mode, by controlling first sub-pixels corresponding to the same light emitting area for providing gray scale information of different viewpoint images to display different gray scale information, the left and right eyes of a person can receive images with different gray scale information when being located at two viewpoints respectively, so as to generate stereoscopic vision and realize naked eye 3D display in a sub-pixel level.

Abstract: A fingerprint identifying device and a fingerprint identifying system are provided.

Abstract: The present disclosure provides a touch display panel and a touch display device, for simplifying the structure of the touch display panel and reducing the cost of the touch display panel. The touch display panel includes an array substrate and an opposite substrate assembled together to form a cell, a sealant located within the edge frame area between the array substrate and the opposite substrate and containing therein a conductive gold ball, a sensing electrode located on a side of the opposite substrate facing away from the array substrate, and a touch drive integrated circuit located on the array substrate. The opposite substrate is provided with, within the edge frame area, a first via hole penetrating the opposite substrate and filled therein with a first conductor, and the sensing electrode is electrically connected with the touch drive integrated circuit via the first conductor and the conductive gold ball.

Abstract: An in-vehicle rear-view display system is described, comprising: a display device comprising a dimming device configured to adjust luminance of light emitted from the display device based on a color change of the dimming device; a first control unit connected with the dimming device and configured to control the color change of the dimming device in accordance with a luminance change of an irradiation light. By arranging in the display device a dimming device capable of adjusting the luminance of light emitted from the display device, the first control unit can control the color change of the dimming device in accordance with the luminance change of the ambient light, and thereby control the luminance of light emitted from the display device so as to preventing glare. Meanwhile, the poor clarity of the screen caused by an anti-glare screen film added to the screen of the display device is avoided.

Abstract: A 3D display device and a driving method thereof are disclosed. The 3D display device comprises a grating and a display panel, and 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.

Abstract: The present disclosure provides a 3D display apparatus and a 3D display method.
