Abstract
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 (μLED), a supporting wall, a first bottom electrode located between the supporting wall and the μLED, and a first top electrode disposed on the supporting wall and separated from the first bottom electrode. The μLED 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 μLED.
