摘要： An LED panel including a substrate, multiple first pixels, multiple second pixels, multiple first protrusion structures and second protrusion structures is provided. The first pixels and second pixels each disposed in a display area of the substrate has at least one light emitting element. The second pixels are positioned on at least one display edge of the display area and positioned between the first pixels and a substrate edge. Each first protrusion structure is positioned on the periphery of the at least one light emitting element of one corresponding first pixel. Each second protrusion structure is positioned on the periphery of the at least one light emitting element of one corresponding second pixel. The orthogonal projection contour of each first protrusion structure on the substrate is different from that of each second protrusion structure on the substrate. A tiling display apparatus adopting the light emitting diode panel is also provided.

摘要： A pixel array substrate has a plurality of sub-pixel regions, wherein a pixel structure of an individual sub-pixel region includes a first signal line, a second signal line, a first contact pad, a second contact pad, a light-emitting diode, a first conductive structure, and a flux structure layer. The first contact pad and the second contact pad are respectively electrically connected with the first signal line and the second signal line. The light-emitting diode is disposed on the first contact pad. A portion of the first conductive structure is disposed between the first contact pad and a first electrode of the light-emitting diode. The flux structure layer partially surrounds the first conductive structure and the light-emitting diode. A top portion of the flux structure layer is higher than a top surface of the first electrode and is lower than a bottom surface of a light-emitting layer of the light-emitting diode.
