A display panel and a pixel structure are provided. The pixel structure includes a substrate, a micro light emitting diode (micro LED or &#x3bc;LED), a sidewall structure, a filling layer, and a reflective layer. The substrate has a bearing surface, and the micro LED is disposed on the bearing surface directly or indirectly. The sidewall structure is disposed on the bearing surface and defines at least one accommodation cavity to accommodate the micro LED. The filling layer is filled in the accommodation cavity and surrounds the micro LED. The reflective layer covers a top surface of the filling layer and has a plurality of light-transmissible windows. The micro LED forms, in a vertical projection direction, a vertical projection region in an overlapping region on the reflective layer. Among the light-transmissible windows, those having longer distances to the vertical projection region have larger areas.

Display panel and pixel structure thereof

A pixel array substrate and a driving method of a pixel array substrate are provided. The pixel array substrate includes a substrate, at least one pixel structure located on the substrate and a liquid crystal layer. The at least one pixel structure includes a micro light emitting diode (&#x3bc;LED), a supporting wall, a first bottom electrode located between the supporting wall and the &#x3bc;LED, and a first top electrode disposed on the supporting wall and separated from the first bottom electrode. The &#x3bc;LED includes a first electrode, a first semiconductor layer electrically connected to the first electrode, a second semiconductor layer, a light-emitting layer located between the first semiconductor layer and the second semiconductor layer, and a second electrode electrically connected to the second semiconductor layer. The liquid crystal layer is disposed on the first bottom electrode and located between the supporting wall and the &#x3bc;LED.

Pixel array substrate and driving method thereof

A method of manufacturing a light emitting device is provided. Multiple light-emitting elements are formed on a substrate in a first density. A first transferring process is performed to transfer the light emitting elements to a transition carrier. The light-emitting elements are disposed on the transition carrier in a second density. The first density is greater than the second density. Multiple electronic devices are disposed on the transition carrier in correspondence with the light-emitting elements. An encapsulation layer is formed on the transition carrier to cover the light emitting elements and the electronic devices. Portions of the encapsulation layer are removed to form multiple package units including the light-emitting elements and the electronic devices. A second transferring process is performed to transfer the package units to an array substrate. The encapsulation layer is removed to expose the light emitting elements and the electronic devices. The light emitting elements and the electronic devices are electrically connected to the array substrate.

Method for manufacturing light emitting device

A self-emission type display including a carrier substrate, a light-emitting element, a first electrode, and a second electrode is provided. The light-emitting element is disposed on the carrier substrate and has a first pad and a second pad. The first electrode has a plurality of first stripe portions electrically connected to a first electric potential. The first pad of the light-emitting element is electrically connected to the carrier substrate through at least one first strip portion. The second electrode has a plurality of second stripe portions electrically connected to a second electric potential. The first electrode and the second electrode are separated from each other. The second pad of the light-emitting element is electrically connected to the carrier substrate through at least one second strip portion. The first electric potential is different from the second electric potential.
