摘要： The flexible circuit board includes: a substrate layer; a first conductive layer; a second conductive layer; a first cover film, a second cover film, a first electromagnetic shielding layer, and a second electromagnetic shielding layer. The part of the first cover film overlapping a first conductive portion has first hollow portions. The part of the second cover film overlapping a second conductive portion has second hollow portions. The orthographic projection of each first hollow portion on the substrate layer has an overlapping area with the orthographic projection of at least one second hollow portion on the substrate layer. The first electromagnetic shielding layer is coupled to the first conductive portion through the first hollow portions. The second electromagnetic shielding layer is coupled to the second conductive portion through the second hollow portions.

摘要： A display panel includes a source driving circuit, a multiplexer circuit, and multiple sub-pixels arranged in an array. The multiplexer circuit is configured to, under the control of a first multiplexing signal to an Nth multiplexing signal, control the source driving circuit to be connected with sub-pixels of one or more columns; and in a jth frame, a multiplexing signal turn-on sequence for sub-pixels of an odd row is from a Jth multiplexing signal to sequentially increasing to the Nth multiplexing signal and from the first multiplexing signal to sequentially increasing to a (J−1)th multiplexing signal, and a multiplexing signal turn-on sequence for sub-pixels of an even row is completely opposite to the multiplexing signal turn-on sequence for the sub-pixels of the odd row.
