Abstract

An assembled LED display device includes a system motherboard, and multiple to-be-assembled daughterboards assembled on the system motherboard. The system motherboard includes a drive power circuit including multiple power lines, and a gate control circuit including multiple gate lines. Each to-be-assembled daughterboard includes a substrate, at least one transistor switch, and a plurality of LED units disposed on the substrate and each including multiple LEDs connected to a same one of the at least one transistor switch. The LEDs of the LED units of the to-be-assembled daughterboards are arranged in a matrix having multiple rows and multiple columns. With respect to each column, the LEDs in the column are connected to the power line corresponding to the column. With respect to each to-be-assembled daughterboard, gate terminal(s) of the at least one transistor switch is(are) connected to the gate line corresponding to the to-be-assembled daughterboard.
