Background
With the development of the lcd technology, the performance requirements of the lcd are higher and higher, and the backlight is required to be high in color gamut and light and thin, so that all manufacturers begin to use QD and iron colloid integrated technology. The integrated backlight structure of the rubber iron is that a light guide plate and a diaphragm are placed in a cavity together, the edges of the light guide plate and the diaphragm are aligned, and poor edges of the backlight are hidden through the letter adhesive adhered to an upper prism and a rubber frame. As shown in fig. 1, a plastic frame wall is injection-molded along the edge of an iron frame 101 to form a cavity together, and a backlight film (including a reflecting sheet 102, a diffusion sheet 103, a brightness enhancement sheet 104) and a light guide plate 105 are placed therein, and edge taste treatment and fixation are performed by means of a black-out adhesive 106 (a mouth-shaped adhesive). Due to the light-condensing characteristic of the edge of the film, the periphery of the backlight is easy to have bad phenomena such as bright lines, blue edges and the like.
At present, a high-color-gamut backlight has a mode that a blue light backlight is used for adding a color conversion film (a diffusion sheet position of the backlight), and the conversion efficiency of the color conversion film is limited due to the fact that a diaphragm cutting edge of the backlight and the edge of a light guide plate are condensed, the whole uniform color conversion film cannot completely convert strong blue light at the edge into white light, and part of blue light with too bright edge cannot be converted, so that the problem of blue edge can be generated.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a rubber-iron integrated backlight structure which reduces the problem of blue edges.
The utility model is realized in the following way:
The utility model provides a glued iron integration structure in a poor light, includes the chase and the glued frame of injection moulding on the chase, glued the frame is echelonment, glue the frame with connect gradually in the cavity that the chase formed installs reflector plate, light guide plate, a plurality of optics diaphragm.
Further, one side of the light guide plate is adhered with an LED lamp.
Further, a fluorescent layer is arranged at the bottom of the rubber frame.
Further, the fluorescent layer is a YAG fluorescent layer.
The utility model has the advantages that:
(1) According to the integrated backlight structure of the rubber iron, the cavity is manufactured below the rubber frame, and the light guide plate and the diaphragm are embedded into the cavity, so that the effect of poor shielding of the edge of the backlight is achieved. Compared with the common iron integrated backlight in the market, the edge taste is better, and the structure is firmer and more stable.
(2) The arranged fluorescent layer can absorb the edge blue light and convert the edge blue light into white light, so that the blue light phenomenon is weakened, and the edge taste of the backlight is further optimized.
(3) The integrated backlight structure of the utility model is suitable for all blue light high color gamut backlights.

Detailed Description
In the description of the present utility model, it should be understood that the description of indicating the orientation or positional relationship is based on the orientation or positional relationship shown in the drawings, and is merely for convenience of description and to simplify the description, rather than to indicate or imply that the apparatus or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be construed as limiting the scope of protection of the present utility model.
In the description of the present utility model, it should be noted that, unless explicitly stated and limited otherwise, the terms "disposed," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.
The technical scheme of the utility model is as follows:
The utility model relates to a glue iron integrated backlight structure, which comprises an iron frame 1 and a glue frame 2 injection-molded on the iron frame 1, wherein the glue frame 2 is in a ladder shape, and a reflecting sheet 3, a light guide plate 4, a diffusion sheet 5 and a light enhancement sheet 6 are sequentially connected and installed in a cavity formed by the glue frame 2 and the iron frame 1. As shown in fig. 2, in the transverse cross-sectional view of the integrated backlight structure of the present utility model, a cavity is formed under the plastic frame 2 during injection molding, and the film material and the light guide plate of the backlight are embedded into the cavity under the plastic frame.
