Abstract

A MiniLED backlight module with a high screen occupation ratio comprises a back plate, a rubber frame, a Mini lamp panel, a membrane group and a lamp panel FPC, wherein the rubber frame is integrated, and the rubber frame and the back plate are integrally designed by rubber iron, so that the rubberizing process of the traditional lamp panel FPC is omitted. The edge of backplate kink is wrapped up to the frame of gluing of FPC position, can protect lamp plate FPC can not by backplate edge fish tail to can reduce the process, avoid gluing the frame to jump simultaneously and take off the risk. A diaphragm group is arranged above the Mini lamp panel, and the diaphragm group and diaphragm ears are pressed on the FPC of the lamp panel. The backlight module can obviously reduce the light-entering side frame, can effectively improve the screen occupation ratio, and for the FPC position, the back plate is bent upwards, the back plate FPC hole is wrapped by the rubber frame, and the FPC protection adhesive tape can be cancelled.

Description

Mini LED backlight module with high screen duty ratio

Technical Field

The utility model belongs to the technical field of display, and particularly relates to a Mini LED backlight module with a high screen occupation ratio.

Background

With the development of display technology, the liquid crystal display device is applied to various electronic products, and since the liquid crystal of the liquid crystal display device does not have a light emitting characteristic, a backlight module is required to be arranged for the liquid crystal display device in order to make the liquid crystal display device display brightness.

As shown in fig. 1-2, the Mini LED backlight modules in the present stage are all double-rubber frames, and the light incident side of the design mode has a single rubber frame, and the rubber frame is wider and occupies a part of the picture area. In addition, the rubber frame is fixed on the lamp panel, the lamp panel is required to be pasted before the rubber frame is pasted, the station attachment can be additionally increased in the attaching process, the labor cost is high, the rubber frame is attached to the lamp, and the risk of tripping of the rubber frame exists.

Disclosure of utility model

Aiming at the defects of the prior art, the utility model aims to provide a Mini LED backlight module with high screen duty ratio so as to solve the problems in the background art.

The aim of the utility model can be achieved by the following technical scheme:

The Mini LED backlight module with the high screen occupation ratio comprises a back plate, a rubber frame, a Mini lamp panel, a membrane group and a lamp panel FPC, wherein the rubber frame is integrally designed, and the rubber frame and the back plate are integrally designed by rubber iron; the edge of the bending part of the backboard is wrapped by the rubber frame at the FPC position;

a diaphragm group is arranged above the Mini lamp panel, and the diaphragm group and diaphragm ears are pressed on the FPC of the lamp panel.

Preferably, the Mini lamp panel is fixedly installed on the backboard through a lamp panel fixing adhesive tape.

Preferably, the panel is fixedly installed on the diaphragm ears of the diaphragm group through a panel fixing adhesive tape.

The utility model has the beneficial effects that:

The backlight module provided by the utility model can obviously reduce the light-entering side frame, can effectively improve the screen occupation ratio, and can cancel the FPC protection adhesive tape by bending the back plate upwards and wrapping the back plate FPC hole by the adhesive frame for the FPC position. And an integrated process is adopted for the back plate of the rubber frame, and the FPC is borne above the rubber frame, so that the diaphragm ears press the FPC of the lamp panel. For the non-FPC position, the back plate rubber frame is integrated with rubber iron, a rubber frame fixing adhesive tape is canceled, and the other three side rubber frames are designed integrally with rubber iron.
