摘要： A micro light emitting diode display device includes a circuit substrate, a plurality of positioning protrusions disposed on the circuit substrate, and a plurality of micro light emitting diodes. Each positioning protrusion has a positioning side surface and a bottom surface. A first angle is included between each positioning side surface and the corresponding bottom surface. The positioning protrusions form positioning spaces on the circuit substrate. The micro light emitting diodes are disposed in the separated positioning spaces and are electrically connected to the circuit substrate. Each micro light emitting diode has a light emitting surface and a side surface. Each light emitting surface is located at a side of the corresponding micro light emitting diode away from the circuit substrate. A second angle is included between each side surface and the corresponding light emitting surface and is less than 90 degrees and greater than or equal to the first angle.

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 device includes a display back plate having a first connecting electrode and a second connecting electrode, a micro LED structure disposed on the display back plate, and a first bonding structure and a second bonding structure disposed between the display back plate and the micro LED structure. The micro LED structure includes an epitaxial structure, and a first electrode and a second disposed on the side of the epitaxial structure closest to the display back plate. The orthogonal projections of the extension portions of the first electrode and the second electrode both exceed the orthogonal projection of the epitaxial structure on the display back plate. Neither the orthogonal projection of the first bonding structure nor the orthogonal projection of the second bonding structure overlaps the orthogonal projection of the bottom surface of the epitaxial structure on the display back plate.
