Description

A new ultra-narrow bezel backlight

technical field

The utility model relates to the technical field of production of backlight sources for electronic products, in particular to a novel ultra-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, the backlight source of the mobile phone usually adopts a plastic frame or a combination of plastic and iron frame as the frame. A light-shielding film is pasted on the frame. Attach the touch screen or the glass cover on the top, and the touch screen or the glass cover is pasted on the mobile phone shell. If you want to minimize the shape of the mobile phone while maximizing the display area, you must make the mobile phone case the narrowest. At the same time, the touch screen, display screen, and backlight need to be the narrowest outside the area where the backlight does not emit light, and the outside of the backlight must be the narrowest. It is too narrow to paste and fix the optical film, and at the same time, it is impossible to fix the display screen, which restricts the narrowness from the display area to the frame of the mobile phone.

Utility model content

The purpose of the present invention is to address the deficiencies of the prior art, and the utility model relates to a novel ultra-narrow frame backlight source.

In order to achieve the above purpose, the utility model adopts the following technical scheme: a novel ultra-narrow frame backlight source, including a reflector (8), and the reflector (8) is provided with a hollow cavity composed of four frame strips. frame body (1), the frame strips are respectively arranged on the edge of the reflective sheet and flush with the edge of the reflective sheet, the front surface of the frame strip is provided with a first adhesive layer (2) for fixing on the display screen, The back of the frame bar is provided with a second adhesive layer (3) connected to the reflection sheet (8), and the first light-increasing film (4) and the second light-increasing film are arranged in the hollow cavity from top to bottom. (5), diffusion film (6), light guide plate (7), LED light source light bar (9), the upper end of the LED light source light bar (9) is provided with an adhesive layer (10) for fixing on the display screen , the upper and lower surfaces of the LED light source light bar (9) are provided with heat dissipation protrusions.

Preferably, the frame (1) is made of PET or plastic or metal.

Preferably, the frame body (1), the first adhesive layer (2) and the second adhesive layer (3) are integrally punched or punched by the same process.

Preferably, the light emitting side of the LED light source light bar (9) is provided with a light concentrating element for converging the light emitted by the LED light source light bar so as to reduce the light emitting angle of the LED light emitting unit. In this way, the loss of light efficiency when light enters the light guide plate is reduced, the utilization rate of light is improved, energy consumption is reduced, and the display brightness of the product is increased.

The beneficial effects of the utility model are as follows: the frame body (1), the first adhesive layer (2) and the second adhesive layer (3) made of PET/plastic/metal are integrally punched or punched by the same process, and the frame The body (1) replaces the traditional plastic frame/glue-iron integration/metal frame, the second adhesive layer (3) is fixed on one side of the PET/plastic/metal frame (1), and the second adhesive layer (3) is The reflection sheet (8) is fixed on one side, the first adhesive layer (2) is fixed on the PET/plastic/metal frame (1), and the first adhesive layer (2) is fixed on the display screen (12); the utility model Under the same circumstances, the display area can be made the largest while the shape of the mobile phone remains unchanged, and the border of the non-display area can be made narrower. At the same time, it solves the complex dispensing process of the iron frame, and the narrow ribs of the plastic frame are difficult to form and easy to break , The light-shielding film is too narrow to assemble and easy to deviate/high assembly precision requirements/high film cutting process requirements and other issues.

detailed description:

As shown in Figures 1 to 3: a novel ultra-narrow frame backlight of the utility model includes a reflector (8), and the reflector (8) is provided with a frame composed of four frame strips with a hollow cavity. Body (1), the frame strips are respectively arranged on the edge of the reflective sheet and are flush with the edge of the reflective sheet, and the front surface of the frame strip is provided with a first glue layer (2) for fixing on the display screen (12) ), the back of the frame bar is provided with a second adhesive layer (3) connected to the reflector (8), and the first light-enhancing film (4), the second light-enhancing film (4) and the second Brightening film (5), diffusion film (6), light guide plate (7), LED light source light bar (9), the upper end of the LED light source light bar (9) is provided with an adhesive layer for fixing on the display screen ( 10), the upper and lower surfaces of the LED light source light bar (9) are provided with heat dissipation protrusions.

Preferably, the frame (1) is made of PET or plastic or metal.

Preferably, the frame body (1), the first adhesive layer (2) and the second adhesive layer (3) are integrally punched or punched by the same process. This molding structure replaces the traditional plastic frame/plastic-iron integration/metal frame. Figure 3 is an enlarged view of A in Figure 2. After the backlight is assembled, the display screen (12) is directly assembled.

Preferably, the light emitting side of the LED light source light bar (9) is provided with a light concentrating element for converging the light emitted by the LED light source light bar so as to reduce the light emitting angle of the LED light emitting unit. In this way, the loss of light efficiency when light enters the light guide plate is reduced, the utilization rate of light is improved, energy consumption is reduced, and the display brightness of the product is increased.

The above embodiment is only a description of the preferred implementation of the utility model, and is not intended to limit the scope of the utility model. On the premise of not departing from the design spirit of the utility model, ordinary engineers and technicians in the field made the technical solution of the utility model Various modifications and improvements should fall within the protection scope determined by the claims of the present utility model.
