Abstract
A micro LED transparent display has a first display surface and a second display surface, which are opposite to each other. The micro LED transparent display includes a substrate, pixels and at least one grating layer. The first display surface and the second display surface are located on two opposite sides of the substrate, respectively. The pixels are arranged in arrays on the substrate, each of the pixels includes micro LEDs, and the micro LEDs are electrically connected to the substrate. The grating layer is disposed on the substrate, and the micro LEDs are located between the grating layer and the substrate. Lights generated from the micro LEDs of the pixels can be controlled by the grating layer, and the lights partially penetrate through the first display surface and are partially reflected and penetrate through the second display surface.
