摘要： A micro light-emitting display device having multiple display regions is provided. The micro light-emitting display device includes a substrate, multiple micro light-emitting elements, and multiple first light-emitting auxiliary structures. The micro light-emitting elements are disposed on the substrate, and positions of the micro light-emitting elements define ranges of the display regions. The micro light-emitting elements have a same first pitch between each other in any one of the display regions. The micro light-emitting elements have a second pitch between each other at a boundary across any two adjacent display regions. The first pitch is different from the second pitch. The light-emitting auxiliary structures are respectively disposed on the micro light-emitting elements. The light-emitting auxiliary structures have a same third pitch between each other.

摘要： A micro LED display includes a display substrate, a first soldering layer, at least one second soldering layer, first micro LEDs and at least one second micro LED. The display substrate includes a substrate having a plurality of pixel areas, a first circuit layer and a second circuit layer, and the first circuit layer and the second circuit layer are arranged in each pixel area. The first soldering layer is disposed on the first circuit layer, and the second soldering layer is disposed on the second micro LED. An arranging area of the first soldering layer is greater than an arranging area of the second soldering layer. The first micro LEDs is bonding to the first circuit layer in each pixel area through the first soldering layer. The second micro LED is bonding to the second circuit layer of one of the pixel areas through the second soldering layer.
