Abstract

The utility model relates to an optical combination of a display, which comprises an optical film group; the upper surface of the optical film group is covered with glass; the lower surface of the optical film group is covered with a light guide plate or a diffusion plate; the glass and the edge of the light guide plate or the diffusion plate are sealed between the glass and the light guide plate or the diffusion plate by using an adhesive tape, and a closed cavity is formed. The utility model provides an optics combination seals the optical film group in the cavity, prevents that after filth such as dust, granule from getting into the optical film, fish tail, wearing and tearing optical film influence display quality, improve the display quality of display under the more environment of dust.

Description

Optical combination of display

Technical Field

The present invention relates to an optical assembly, and more particularly to an optical assembly for a display.

Background

The LCD comprises a light source, a light guide plate (or a diffusion plate), a reflection sheet, an optical film group and a liquid crystal screen. The optical film group is positioned between the light guide plate (or the diffusion plate) and the liquid crystal screen and is not sealed. Because the use of the optical film has higher requirements on the environment, when the optical film is used in an environment with more dust, the optical film can be scratched and abraded after dust, particles and other dirt enter the optical film group, and the display quality is influenced.

The prior art emphasizes and solves the dustproof structure of the whole display screen, so that the dustproof structure aiming at the optical film group is needed.

Disclosure of Invention

1. The technical problem to be solved is as follows:

to the technical problem, the utility model provides an optical assembly of display prevents dust to the optical module that is destroyed by the dust easily in the display screen structure.

2. The technical scheme is as follows:

an optical assembly for a display, comprising: comprises an optical film group; the upper surface of the optical film group is covered with glass; the lower surface of the optical film group is covered with a light guide plate or a diffusion plate; the glass and the edge of the light guide plate or the diffusion plate are sealed between the glass and the light guide plate or the diffusion plate by using an adhesive tape, and a closed cavity is formed.

Furthermore, the optical film group sequentially comprises a polarized light brightness enhancement film, two prism films and a diffusion film from top to bottom.

Furthermore, the optical film group comprises a diffusion film, two prism films and a diffusion film from top to bottom in sequence.

Further, the thickness of the adhesive tape is larger than the total thickness of the optical film group.

3. Has the advantages that:

(1) the utility model provides an optics combination seals the optical film group in the cavity, prevents that after filth such as dust, granule from getting into the optical film, fish tail, wearing and tearing optical film influence display quality, improve the display quality of display under the more environment of dust.

(2) The utility model discloses simple structure easily realizes, can be used for multiple display.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

As shown in fig. 1, an optical assembly for a display, comprising: comprises an optical film group 2; the upper surface of the optical film group is covered with glass 3; the lower surface of the optical film group is covered with a light guide plate or/and a diffusion plate 1; the glass and the edge of the light guide plate or the diffusion plate are sealed by an adhesive tape 4 to form a closed cavity.

In the embodiment, as shown in fig. 1, the light passing through the light guide plate passes through the optical film assembly and is transmitted out of the glass, and the optical film is sealed in the closed space by the glass, the adhesive tape, the light guide plate/the diffusion plate, so that the dirt such as dust and particles can be prevented from entering the optical film.

Although the present invention has been described with reference to the preferred embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.

Claims

1. An optical assembly for a display, comprising: comprises an optical film group; the upper surface of the optical film group is covered with glass; the lower surface of the optical film group is covered with a light guide plate/a diffusion plate; the edge of the glass and the edge of the light guide plate or the diffusion plate seals the optical film group between the glass and the light guide plate or the diffusion plate by using an adhesive tape and forms a closed cavity;

the optical film group sequentially comprises a polarized light brightness enhancement film, two prism films and a diffusion film from top to bottom; or the optical film group comprises a diffusion film, two prism films and a diffusion film from top to bottom in sequence.

2. An optical combination for a display according to claim 1, wherein: the thickness of the adhesive tape is larger than the total thickness of the optical film group.
