Abstract
A pixel structure is provided. The pixel structure includes a substrate, a micro light-emitting diode, and an electrophoretic structure. The micro light-emitting diode is disposed on the substrate and configured to emit light. The electrophoretic structure is disposed on the micro light-emitting diode and includes an upper electrode, a lower electrode, an electrophoretic medium, and an electrophoretic lens. The electrophoretic medium is disposed between the upper electrode and the lower electrode, wherein the electrophoretic medium has a first refractive index. The electrophoretic lens is disposed in the electrophoretic medium and has a second refractive index that is different from the first refractive index. The electrophoretic lens is configured to move away from or toward the micro light-emitting diode by being driven by the electric field, so that light passing through the electrophoretic lens has a first or second divergence angle after refracting.
