Abstract
Disclosed is a light-emitting array structure having a substrate, a plurality of light-emitting pixel units, a plurality of first and second signal wires, and an encapsulating layer. The light-emitting pixel units are arranged in array on the substrate. Each light-emitting pixel unit includes a driving chip, a first flat layer, a first redistribution layer, a second flat layer, a second redistribution layer, and a light-emitting diode. Each first signal wire is electrically connected to a corresponding one of the first redistribution layers and extends in a first direction. The second signal wires extend in a level different from the first signal wires. Each second signal wire is electrically connected to a corresponding one of the second redistribution layers and extends in a second direction different from the first direction. The encapsulating layer covers the light-emitting pixel units, the first and second signal wires, and the substrate.
