A light emitting diode (LED) display device, comprising:
- a substrate;
- a plurality of pixel units arranged in array on the substrate, wherein each of the plurality of pixel units comprises three LEDs with different emitting colors, and the three LEDs are a red LED, a green LED and a blue LED;
- a lateral through line in each row of the plurality of pixel units, which is connected directly with a first electrode of each LED in each row of the plurality of pixel units and configured to load a first signal for driving the first electrode, the lateral through line and the plurality of pixel units are arranged on a same side of the substrate;
- and
- a first vertical through line, a second vertical through line and a third vertical through line in each column of the plurality of pixel units, arranged on an opposite side of the substrate to the plurality of pixel units, which are electrically connected with a second electrode of each LED in the each column of the plurality of pixel units and configured to load a second signal for driving the second electrode,
- wherein in each of the plurality of pixel units, the second electrode of the red LED is electrically connected with the first vertical through line via a first via hole, the second electrode of the green LED is electrically connected with the second vertical through line via a second via hole, and the second electrode of the blue LED is electrically connected with the third vertical through line via a third via hole,
- wherein in each row of the plurality of pixel units, one of an beginning end and an ending end of the lateral through line is electrically connected with a first pin of a driving chip via a first through hole,
- wherein in a pair of adjacent rows of the plurality of pixel units, the first through hole in one row of the pair of adjacent rows is arranged at the ending end of the lateral through line in the one row of the pair of adjacent rows, and the first through hole in the other row of the pair of adjacent rows is arranged at the beginning end of the lateral through line in the other row of the pair of adjacent rows.
