Description

An Improved Narrow Bezel Backlight

Technical field:

The utility model relates to the technical field of production of backlight sources for electronic products, in particular to an improved narrow-frame backlight source.

Background technique:

With the development of mobile phone technology, people increasingly want to make the display area of the mobile phone larger when the shape of the mobile phone remains unchanged, so that people can use it more conveniently.

At present, Sharp and LG have achieved a distance of 0.6mm from the outside to the visible area of the mobile phone LCD. The side of the LCD display is getting narrower and narrower. At the same time, the backlight needs to be narrower and narrower from the outside to the light-emitting area. The light-shielding glue that sticks the backlight to the LCD becomes narrower and narrower, and the viscosity of the light-shielding glue will decrease after making it narrower. When the mobile phone falls or vibrates, the backlight may become loose or fall off, which will affect the display effect of the mobile phone.

Utility model content:

The purpose of the present invention is to address the deficiencies of the prior art, using metal as the backlight source frame, using the upper light-enhancing film to protrude several ears, and the light-shielding film sticking to the fixed ears protruding from the upper light-enhancing film, and at the same time pasting the light-shielding film on the metal On the frame, fix the optical film and light guide plate in the metal frame, so as to achieve the effect of narrowing the backlight from the outside to the light-emitting area, and make some small gaps on each side around the metal frame for dispensing glue, so as to strengthen the backlight Stickiness with LCD. When the phone is dropped or vibrated, the backlight will not loosen or fall off.

In order to achieve the above object, the utility model adopts the following technical scheme: the lower end of the light-shielding film is provided with an upper light-enhancing film, a lower light-enhancing film, a diffusion film, a light guide plate, a reflection sheet, and a metal frame, and an LED light bar is arranged on the light guide plate. , There are fixed ears protruding from the upper light-enhancing film, the light-shielding film is pasted on the fixed ears, there are gaps around the metal frame, and there are installation grooves for installing the fixed ears around the metal frame.

There are more than two fixed ears.

The gaps are more than two.

The beneficial effects of the utility model are as follows: the lower end of the light-shielding film is provided with an upper light-enhancing film, a lower light-enhancing film, a diffusion film, a light guide plate, a reflection sheet, and a metal frame; Fixed ears, the light-shielding film is pasted on the fixed ears, there are gaps around the metal frame, and a few ears are protruded by the upper light-enhancing film, and the light-shielding film is pasted on the fixed ears protruding from the upper light-enhancing film, and the light-shielding film is pasted on the metal frame at the same time , fix the optical film and light guide plate in the metal frame, so as to achieve the effect of narrowing the backlight from the outside to the light-emitting area, and make some small gaps on each side around the metal frame for dispensing, so as to strengthen the backlight and LCD stickiness. When the phone is dropped or vibrated, the backlight will not loosen or fall off.

Description of drawings:

Fig. 1 is the structural representation of the utility model.

Fig. 2 is a sectional view of the utility model.

Detailed ways:

See Fig. 1 to Fig. 2: the utility model comprises that the lower end of the shading film 1 is sequentially provided with an upper light-enhancing film 2, a lower light-enhancing film 3, a diffusion film 4, a light guide plate 5, a reflection sheet 6, a metal frame 7, and a light guide plate 5 There is an LED light bar 8 on the top, and fixed ears 21 protrude from the upper light-enhancing film 2, and the light-shielding film 1 is pasted on the fixed ears 21. There are gaps 71 around the metal frame 7, and there are also fixed ears for installation around the metal frame 7. 21 mounting slot 72.

There are more than two fixing ears 21 .

The number of notches 71 is more than two.

Metal is used as the metal frame 7 of the backlight 8, and the light-shielding film 1 is pasted on the four folded edges of the metal frame 7 at the same time, so that the optical film material and the display screen 9 can be fixed, and the display screen 9 is provided with a touch screen 11. The 7 sides of the metal frame are fixed on the mobile phone shell 10, so that it is equivalent to sticking the display screen 9 on the mobile phone shell indirectly. Under the same circumstances, the display area can be the largest when the shape of the mobile phone remains unchanged. The light-shielding film 1 sticks the protruding fixed ear 21 of the upper light-enhancing film 2, and at the same time sticks the light-shielding film 1 on the metal frame to fix the optical film material and the light guide plate 5 in the metal frame, so as to achieve the backlight from the outside to the light-emitting area. The edge of the metal frame is made to have a narrow effect, and some gaps 71 are made on each side around the metal frame for dispensing glue, thereby strengthening the adhesion between the backlight and the LCD. When the phone is dropped or vibrated, the backlight will not loosen or fall off.

The above is only a preferred embodiment of the utility model, so all equivalent changes or modifications made according to the structure, features and principles described in the utility model patent application scope are all included in the utility model patent application scope .
