Abstract: Provided are a demultiplexer circuit, an array substrate, a display panel and device, and a driving method. The demultiplexer circuit includes multiple demultiplexers, each demultiplexer includes at least two switching transistor groups, and each switching transistor group includes at least two switching transistors. Sources of the at least two switching transistors in a same switching transistor group are electrically connected to each other, drains of the at least two switching transistors in the same switching transistor group are electrically connected to each other. Input ends of the at least two switching transistor groups in a same demultiplexer are electrically connected to each other. In the same switching transistor group, the common source is electrically connected to the input end, the common drain is electrically connected to the output end, and at least two control ends are electrically connected to gates of the switching transistors in a one-to-one correspondence.
