Abstract
A backlight module includes: a plurality of lamp groups arranged in an array on a base substrate, each lamp group comprises a plurality of mini light emitting diodes, a plurality of lead wires in the lamp group, an external anode and an external cathode; a plurality of anode wires and cathode wires electrically connected to external anodes and external cathodes of a plurality of rows of lamp groups, respectively, wherein in at least some of the plurality of cathode wires, one same cathode wire is electrically connected to the external cathodes of the lamp groups located in different rows. Same-type anode wires comprise a plurality of anode wires to which same-wire lamp groups are connected, and orthographic projections of the same-type anode wires on the base substrate do not overlap with an orthographic projection of one same lead wire in the lamp group on the base substrate.
