• the front case is a metal front case.
• the embodiment of the invention can effectively avoid the display problem caused by the extrusion of the LCD module.
• the design reserved gap between the front cover and the LCD backlight portion, the LCD display portion and the touch screen can be made smaller. It is also conducive to the thin design of the whole machine.
• the front shell is designed with a step/clip for installing the film of the backlight portion of the LCD module, which facilitates the assembly of the film.
• the display portion of the LCD module directly contacts the rubber frame of the front shell, effectively reducing the module frame and narrowing the whole machine.
