Abstract: Disclosed in the present disclosure are an OLED display panel, a driving method therefor and a display device. A first light-blocking layer is disposed between a photosensitive unit and an organic electroluminescent structure, and the first light-blocking layer at least has a hollow area corresponding to a fingerprint identification area. When a finger touches a screen, the lights emitted by the organic electroluminescent structure are reflected by the finger to irradiate the photosensitive unit through small holes, such that fingerprint information of the finger is detected due to the brightness differences among the lights reflected by ridges and valleys of the finger. The small holes in the hollow area can function to improve the light intensity convergence, thus increasing the sensitivity to finger touches to the greatest extent.

Abstract: The present invention provides a method for preparing an uneven particle layer, an organic light emitting diode device and a display device. The method for preparing an uneven particle layer includes the following steps: forming a nanoparticle layer on a substrate; heating the substrate to fuse nanoparticles that are in contact with the substrate, whereas the nanoparticles on the surface keep a solid state; and cooling the substrate to form a nanoparticle layer with an uneven surface. The method of the present invention is simple in process, and industrial production is easy to achieve. The substrate including the uneven particle layer is applied to the OLED device, so the propagation direction of rays can be changed so as to avoid total reflection on an interface and thus improve the light extraction efficiency of the OLED device. The OLED device prepared in the present invention is suitable for various display devices.

Abstract: The present disclosure relates to the technical field of liquid crystal display. A liquid crystal panel and a display panel are provided. A main post spacer of the liquid crystal panel is arranged on a first substrate. A stopping structure used to stop the main post spacer from moving in a direction away from a second substrate is arranged on the second substrate. Hence, even if lots of liquid crystals are filled, the main post spacer and the second substrate may be kept in a seamless state due to the stopping structure.
