Abstract
A micro LED display panel which is transparent to ambient light includes a TFT substrate, a plurality of micro LEDs, a first insulating layer, and a second insulating layer. The TFT substrate includes a first surface and a second surface. The micro LEDs and the first insulating layer are on the first surface. The first insulating layer is transparent. The second insulating layer includes insulating units spaced from each other and made of a light absorbing material. Each insulating unit is on a side of the first insulating layer away from the TFT substrate and each micro LED is embedded in the first insulating layer and in one of insulating units. Regions of the TFT substrate not covered by the insulating layer are regions which allow light to pass through.
