According to the utility model, the concave holes are formed in the edges of the iron frame, so that the rubber frame can be formed on the inner side of the iron frame in an injection molding mode and is integrally connected with the iron frame, and the assembly efficiency and the structural stability of the backlight source are improved.

Description

Rubber frame and iron frame integrated backlight source

Technical Field

The utility model relates to the technical field of backlight sources, in particular to a rubber frame and iron frame integrated backlight source.

Background

The backlight source is a light source positioned at the back of the liquid crystal display, the luminous effect of the backlight source directly influences the visual effect of the liquid crystal display module, the liquid crystal display does not emit light, and the backlight source displays figures or the result of light modulation.

The rubber frame and the iron frame of the existing backlight source are usually arranged in a split mode, the rubber frame is assembled on the inner side of the iron frame after injection molding, production efficiency is low, and structural stability is poor.

SUMMERY OF THE UTILITY MODEL

In order to overcome the above-mentioned drawbacks of the prior art, embodiments of the present invention provide an integrated backlight with a rubber frame and an iron frame to solve the above-mentioned problems in the background art.

In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a glue frame chase integral type backlight, includes chase and optical film material, the inner wall scarf joint of chase has gluey frame, the optical film material is located the inner wall of chase, the upper surface of optical film material is equipped with the black glue, the penetrability shrinkage pool has been seted up on the lower surface limit at chase edge, glue frame injection moulding in the inboard of chase to the part of gluing the frame inlays in the inside messenger of shrinkage pool and glues frame and chase body coupling.

Preferably, the inside of optical film material is equipped with the lamp strip, the upper surface edge of optical film material has the ebonite of veneer.

Preferably, the inner wall of the rubber frame is uniformly and fixedly provided with a convex block, and the lower surface of the convex block is tightly attached to the upper surface of the black rubber.

Preferably, a penetrating concave hole is formed in the side edge of the iron frame.

Preferably, the diameter of the concave hole is 0.4-1.2 mm.

The utility model has the technical effects and advantages that:

1. the concave holes are punched at the edge of the iron frame through the arrangement, so that the rubber frame can be molded in an injection mode on the inner side of the iron frame and is integrally connected with the iron frame, and the assembling efficiency and the structural stability of the backlight source are improved.

2. Be provided with the lamp strip through setting up in the backlight, set up non-sticky black glue through locating at the lamp strip to prevent LCD screen and black glue adhesion when the dress from having avoided the LCD screen to take the lamp strip, make the demonstration inhomogeneous.

FIG. 2 is a schematic view of the structure of the lower surface of the chase of the present invention.

Fig. 3 is a schematic top view of the iron frame of the present invention.

The reference signs are: 1. an iron frame; 2. a rubber frame; 3. an optical film material; 4. black glue; 5. a concave hole.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

1-3 shows a frame iron integral type backlight, including iron frame 1 and optical film material 3, the inner wall of iron frame 1 has inlayed and has glued frame 2, and optical film material 3 is located the inner wall of iron frame 1, and the upper surface of optical film material 3 is equipped with black adhesive 4, and penetrability shrinkage pool 5 has all been seted up to the lower surface and the side at iron frame 1 edge, the diameter of shrinkage pool 5 is 0.4 ~ 1.2 mm. Glue frame 2 and mould in the inside of shrinkage pool 5, and with the inner wall fixed connection of chase 1, wherein the backlight subassembly comprises multilayer film, through setting up shrinkage pool 5 that punches in 1 border department of chase to make gluey frame 2 can injection moulding in chase 1's inboard, and the part of gluing frame 2 inlays and makes gluey frame 2 and chase 1 body coupling in the inside of shrinkage pool 5, improve the packaging efficiency and the structural stability of backlight.

Be equipped with the lamp strip through the inside that sets up optical film material 3, the upper surface edge veneer of optical film material 3 has black glue 4 to prevent LCD screen and 4 adhesions of black glue when adorning at the LCD screen, avoid the LCD screen to bring up the lamp strip, make the demonstration inhomogeneous.

The working principle of the utility model is as follows: when the device normally used, will glue frame 2 and mould plastics in the inner wall department of chase 1 to shrinkage pool 5 is irritated into to the bottom, lets chase 1 and glue frame 2 be the integral type and connects, is equipped with the lamp strip in the device body inside, and seals the edge at optical film material 3 with black glue 4, prevents its and 4 adhesions of black glue when being used for installing the LCD screen, avoids the LCD screen to take up the lamp strip, makes to show inhomogeneously.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
