Abstract

A spliced micro light-emitting-diode display panel includes multiple circuit boards spliced with each other and multiple micro light-emitting-diode modules. Each circuit board includes at least one driver IC. The micro light-emitting-diode modules are disposed separately on each circuit board and are electrically connected to the driver IC. Each micro light-emitting-diode module includes multiple light-emitting-diode units arranged in an array. On each circuit board, the driver IC drives the light-emitting-diode units of the micro light-emitting-diode modules to emit light. There is a first gap between any adjacent two of the light-emitting-diode units on any adjacent two of the circuit boards, and there is a second gap between any adjacent two of the light-emitting-diode units on each micro light-emitting-diode module, and the first gap is smaller than the second gap.
