(a) providing a first mold assembly with a first formation cavity for injection molding a cover and a second mold assembly for injection molding a plurality of first transparent members, filling a first material into the first formation cavity defined by the first mold assembly at a first place to form the cover with a plurality of first through holes, followed by moving the cover to a second place, filling a second material into a second formation cavity defined by the second mold assembly and the cover to seal one of the plurality of the first through holes via a corresponding one of the first transparent members;
and
(b) disposing an ink layer on a display side of the cover in such a manner that the ink layer covers the display side of the cover and that the first transparent member in each of the first through holes is exposed from the ink layer.

A method for manufacturing a housing of an LED display device, comprising the steps of:

(a) injection molding a cover that is formed with a plurality of through holes, followed by injection molding a plurality of transparent members in each of the through holes using a spin double injection machine;
(b) disposing an ink layer on a display side of the cover and an outer surface of the transparent member in each of the through holes using an ink disposing machine;
and
(c) laser engraving a part of the ink layer covering the transparent members so as to forma specific light transparent pattern using a laser engraving machine.
