The disclosure provides a method for preparing an electrode film layer on a surface of a solar cell substrate. The method includes: a) obtaining a metal electrode material melt by heating and melting a metal electrode material under a vacuum condition; b) bombarding the metal electrode material melt with an ion source at low energy, so that it is sputtered and deposited on the surface of the solar cell substrate to form the electrode film layer; in which the energy of low energy bombarding is 30 eV to 80 eV.

A backlight module and a display apparatus are provided. The backlight module includes a film sheet, including a first opening and a second opening; and a light guide plate, including a first limit boss located within the first opening and a second limit boss located within the second opening. The second limit boss limits a position of the film sheet in a first direction; the first limit boss limits the position of the film sheet in a second direction. In the second direction, a first interval between is between a portion of the film sheet that forms the second opening and the second limit boss; and the portion of the film sheet that forms the second opening includes two first sidewalls opposite to each other in the first direction.
