Abstract: Provided are a display motherboard, a preparation method thereof, a display substrate and a display device. The display motherboard includes a plurality of display substrate regions and a cutting region located at a periphery of each of the plurality of display substrate regions; the display motherboard includes a driving structure layer arranged in each of the plurality of display substrate regions and a marking structure layer arranged in each cutting region, wherein the marking structure layer includes a cutting mark layer; and a planarization layer arranged on the driving structure layer and the marking structure layer, and covering the marking structure layer.

Abstract: The present invention discloses a decorative film comprising a colored polymer film layer and a micro/nano-structure layer on a surface of the colored polymer film layer, wherein the micro/nano-structure layer comprises a plurality of colored polymer micro/nano-structures. Due to the colored polymer film layer and the plurality of colored polymer micro/nano-structures, a color with an optical effect can be displayed, the color modulation is reduced and the process is simplified.

Abstract: Disclosed is an electrically-conductive film, comprising a support layer, an electrically-conductive area, a lead, and a bridging part. The support layer comprises a first side and a second side in an opposite arrangement. The support layer is recessively provided with a first groove and a second groove not in communication with each other. The first groove is filled with an electrically-conductive material to form an electrically-conductive area. The second groove is filled with an electrically-conductive material to form a lead. The bridging part is provided on the first side; the bridging part is electrically connected to the electrically-conductive area and to the lead. With the bridging part connected to the electrically-conductive area and to the lead, the connection is of increased reliability, and the electrical conductivity is increased. In addition, also disclosed is a preparation method for the electrically-conductive film.

Abstract: The present disclosure discloses a decorative film comprising a support layer and a texture structure. The support layer comprises a first surface and a second surface opposite to each other. The texture structure is provided on the first surface of the support layer. The first surface defines a plurality of dots, and the texture structure is provided with dot textures showing light and shadow highlights at each of the dots and color matching textures located between the dot textures for color matching. The decorative film can show a plurality of light and shadow highlights by setting the dot textures, such that it has a unique decorative effect and a high recognition. And no dazzling light and shadow highlights of the decorative film are shown and the better visual effects are exhibited by setting the color matching textures.

Abstract: A transparent conductive film includes a substrate defining a mesh-shaped groove, which forms a mesh; and a conductive layer formed by conductive material filled in the mesh. An edge line of the mesh-shaped grooves is a curve or a polyline which increases a contact area between the conductive material and an edge of the mesh-shaped groove. In the transparent conductive film, non-linear edge lines are used, therefore, for the conductive region with the same size, the area of edge of the conductive material in contact with the trench increases, and the friction is increased, which leads to a larger adhesion of the conductive material, and a stable performance of the transparent conductive film is guaranteed.
