Abstract: The present application provides a display panel and a display device. The display panel is divided into a plurality of pixel regions, a thin film transistor is disposed in a pixel region of the plurality of pixel regions, and a gate line and a data line intersect between adjacent ones of the plurality of pixel regions. A photodiode is provided in at least one of an area corresponding to the thin film transistor in the pixel region, an area corresponding to the gate line, or an area corresponding to the data line, and the photodiode is electrically connected to the gate line or the data line.

Abstract: A display substrate, a manufacturing method thereof, and a display device are provided. The manufacturing method of the display substrate includes: forming a pattern of first transparent conductive layer, forming a passivation layer and forming a second transparent conductive layer on the passivation layer, forming a pattern of second transparent conductive layer, i.e., a slit electrode, the pattern of second transparent conductive layer including a plurality of sub-electrodes arranged at intervals and located in a display region of the display substrate; and removing a portion of the passivation layer which is in the display region and is not covered by the sub-electrodes, forming a pattern of passivation layer. The second transparent conductive layer is polycrystalline ITO.

Abstract: An array substrate includes a base substrate and at least three layers of signal lines insulated from each other and arranged in a non-display region. The signal lines include first signal lines in a first layer and second signal lines in a second layer extending in an identical direction, and third signal lines in a third layer crossing the first and the second signal lines. A distance between each third signal line and the base substrate is larger than a distance between each first/second signal line and the base substrate. An orthogonal projection of each first signal line on the base substrate overlaps that of the corresponding third signal line to form a first overlapping region, an orthogonal projection of each second signal line overlaps that of the corresponding third signal line to form a second overlapping region which partially overlaps, or does not overlap, the first overlapping region.

Abstract: The present invention provides a method for detecting a chicken Beard trait. Copy number variations of three DNA fragments were found to be present in the chromosomes of bearded chicken number 27, in the physical locations 1702269-1721521 bp, 4470331-4503417 bp, 3578409-3592890 bp; 3 molecular markers were determined, and 3 pairs of primers were designed for said molecular markers; the method of PCR is used for testing the chicken genome to be tested for the described 3 molecular markers; if the three target fragments of the PCR amplification reaction are 3200 bp, 501 bp, and 411 bp, then the detection result is positive; otherwise, the result is negative.
