Patent ID: 8922533

Claim:
A micro-electro-mechanical (MEM) display module, comprising: a MEM display panel, comprising: a substrate; a plurality first light-shielding units, each of the first light-shielding units comprising a first movable light-shielding device having at least one first opening; a plurality second light-shielding units, the first light-shielding units and the second light-shielding units being arranged in arrays on the substrate, each of the second light-shielding units comprising a second movable light-shielding device having at least one second opening; a light-shielding pattern layer disposed on the substrate and having a plurality of third openings; and a reflective pattern layer disposed on the substrate, wherein the reflective pattern is not light-transmissive; and a light-emitting apparatus disposed beside the MEM display panel, wherein when the MEM display module is in a display mode, the at least one first opening of the first movable light-shielding devices overlaps at least one of the third openings, and each of the second movable light-shielding devices covers the reflective pattern layer, and when the MEM display module is in a reflective mode, the first opening of each of the first movable light-shielding devices is covered by the light-shielding pattern layer, and the second opening of each of the second movable light-shielding devices exposes the reflective pattern layer.
