The patent application relates to a fixed structure of modularized light guide plate and a backlight module, wherein the fixed structure includes a back board, a display panel, a light source, an optical module arranged between the back board and the display panel for receiving the light of the light source, and an aluminum extrusion. The methods involve depositing a sub-layer of the dielectric material on a substrate, followed by treating the sub-layer with a plasma. The plunger is then driven by the coil in an opposed direction, and the force stored within the forced storage mechanism is released, such that the released force and the power force from the coil are combined to drive a nail into a work piece.
