    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: A touch substrate is disclosed, which comprises a substrate, an insulating layer, a first touch electrode, and a second touch electrode. The insulating layer is arranged on the substrate. The first and second touch electrodes are arranged on the substrate, have an overlapping region, and are insulated from each other in the overlapping region through the insulating layer. The substrate is provided with a first trench, in which the first touch electrode is at least partially arranged. By arranging the first touch electrode at least partially in the first trench, the difference in height due to the first touch electrode is reduced or eliminated, and adverse effects on films over the first touch electrode due to the difference in height are reduced or eliminated. A method for fabricating the touch substrate and a touch panel are also disclosed.

    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.
