The light board is fixed to the flexible circuit board through the FPC double-sided adhesive, and the flexible circuit board is fixed to the housing through the FPC reverse edge-wrapping adhesive,

The LED light source and the flexible circuit board are assembled on one end of the light guide plate through the FPC double-sided adhesive, and the LED light source and the flexible circuit board are connected to an external power supply through a metal PIN pin to provide the entire backlight with light source.

The diffusion film is attached to the light guide plate through FPC double-sided adhesive tape, and the brightness enhancement film A and the brightness enhancement film B are attached to the diffusion film in sequence. The inside of the housing is sprayed with black paint, and the head of the housing is The retaining wall is pasted with black and black insulating glue, the entire backlight of the housing is pasted with black and black light-shielding double-sided tape, and the middle part is used to determine the visible area.

Further, the housing is an integrated housing with a plastic shell and an iron frame. The shell is formed by injection molding of the iron frame and the plastic shell. The inner side of the iron frame is sprayed with nanometer black paint, and there is no glue on the left and right sides and the light source end.

Further, the LED in the LED light source is a new type of single linear light-emitting LED.

Further, the thickness of the flexible circuit board is 0.02-1 mm.

Further, the visible area has an area of 0.5-6.0 inches.

The beneficial effects of the utility model are:

The frameless rubber-iron integrated backlight provided by the utility model has an ingenious structural design, which effectively solves the problem that the retaining wall of the conventional backlight and the large glue area occupy a certain visible area, and the mobile phone of the same size cannot achieve a larger For the problem of visible area, the breakthrough of removing the backlight retaining wall and reducing the area of glue to maximize the viewing area under the same shape limit can significantly improve the visual impact effect, and it is easier to meet the needs of consumers and make its performance has been greatly optimized.
