Abstract: The present application provides a display panel and a driving method thereof. The display panel includes an array substrate with a terminal portion and a color filter substrate with a common electrode layer. The display panel further includes a first detection terminal, a second detection terminal arranged away from the terminal portion, first electrical connection wires, and a second electrical connection wire. Both the first detection terminal and the second detection terminal are electrically connected to the common electrode layer. The first detection terminal and the second detection terminal are respectively electrically connected to the terminal portion through corresponding first electrical connection wires. The first detection terminal and the second detection terminal are electrically connected through the second electrical connection wire.

Abstract: This disclosure relates to isolated monoclonal antibodies or antigen-binding fragments thereof that specifically bind to PD-1 and block the interaction between PD-1 and PD-L1/PD-L2. The disclosure also relates to antibodies that are chimeric, humanized, bispecific, derivatized, single chain antibodies, portions of fusion proteins or bispecific antibodies. Nucleic acid molecules encoding the antibodies, hybridomas, and methods for expressing antibodies are also provided. Pharmaceutical compositions comprising the antibodies are also provided. This disclosure also provides use of these antibodies to enhance T-cell function and upregulate cell-mediated immune responses for the treatment and prevention of various diseases.

Abstract: An electrical connector includes an insulating body having a main body and a mating portion. The main body includes a base and an insertion portion extending forward from the base. The mating portion protrudes forward out of the insertion portion. A metal latch member is mounted on the main body and provided with a latch portion to latch a mating connector. Multiple conductors are respectively received in the mating portion. Multiple cables are electrically connected to the conductors. An assisting member is fixed to the base and extending forward relative to the base. A first position limiting slot is formed between the assisting member and the mating portion. A second position limiting slot is formed between the assisting member and the insertion portion, and is in communication with the first position limiting slot. The latch portion is upward exposed out of the assisting member.
