摘要： A micro semiconductor chip, a micro semiconductor structure, and a display device are provided. The micro semiconductor chip includes an epitaxial layer, a first electrode, a second electrode and a side light guide element. The epitaxial layer has a top surface, a bottom surface and a side surface. The first electrode and the second electrode are disposed on the bottom surface of the epitaxial layer. The side light guide element disposed on the side surface has a connecting portion and an extending portion. The connecting portion is in contact with a part of the extending portion, and the extending portion extends away from the side surface of the epitaxial layer. The extending portion has a top surface and a bottom surface, wherein a plane containing the top surface of the epitaxial layer forms an acute angle θ1 with a plane containing the top surface of the extending portion.

摘要： 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.
