| description | The embodiment of the invention provides a method for manufacturing an optical diaphragm for a backlight module and the optical diaphragm. The method comprises the steps that parameters of an ultrashort pulse laser are set; the ultrashort pulse laser is guided to the first surface of a base plate made of a brittle material for being scanned in order to form a plurality of blind holes in the firstsurface of the base plate, and the brittle material optical diaphragm with the multiple blind holes is obtained. By means of the method for manufacturing the optical diaphragm for the backlight module, because the ultrashort pulse laser is adopted, namely a cool laser processing technology is adopted, the quality of the blind holes formed in the brittle material base plate can be significantly improved, and accordingly, the quality of the obtained optical diaphragm can be significantly improved.
