Claim 0:
1. A spliced micro light-emitting-diode display panel, comprising:
a plurality of circuit boards, spliced with each other, wherein each of the plurality of circuit boards comprises at least one driver IC; and
a plurality of micro light-emitting-diode modules, disposed separately on each of the plurality of circuit boards and connected electrically with the at least one driver IC, wherein each of the plurality of micro light-emitting-diode modules comprises a plurality of light-emitting-diode units disposed in an array, on each of the plurality of circuit boards, the at least one driver IC drives the plurality of light-emitting-diode units of the plurality of micro light-emitting-diode modules to emit light, wherein a first gap exists between any adjacent two of the plurality of light-emitting-diode units respectively on any adjacent two of the plurality of circuit boards, and a second gap exists between any adjacent two of the plurality of light-emitting-diode units on each of the plurality of micro light-emitting-diode modules, and the first gap is smaller than the second gap,
wherein each of the plurality of micro light-emitting-diode modules further comprises:
a multilayer circuit layer, comprising a top circuit layer and a bottom circuit layer, wherein the bottom circuit layer comprises a plurality of pads;
a plurality of micro light-emitting diodes, disposed on the top circuit layer of the multilayer circuit layer, and adapted to define the plurality of light-emitting-diode units, wherein each of the plurality of light-emitting-diode units comprises three of the plurality of micro light-emitting diodes separated from each other, and an orthographic projection of each of the plurality of light-emitting-diode units on the bottom circuit layer completely overlaps within a corresponding one of the plurality of pads; and
a light-transmitting flat layer, adapted to cover the top circuit layer of the multilayer circuit layer and the plurality of micro light-emitting diodes.
