Abstract

The invention discloses an optical membrane module resistant to strong vibration. Two bosses are arranged on each of long sides of a brightening membrane, a boss is arranged on each of short sides of the brightening membrane, the structure of a diffusion membrane is the same as that of the brightening membrane, insulation foam is attached to the periphery of upper reinforcement glass, openings matched with the bosses are arranged at corresponding positions on the insulation foam, the brightening membrane is arranged on the upper reinforcement glass and positioned in a frame defined by the insulation foam, the bosses on the brightening membrane are bonded into the openings of one long side and the short side adjacent to the long side of the frame, the diffusion membrane is positioned above the brightening membrane, bosses on the diffusion membrane are bonded into the openings on the other long side and the short side adjacent to the long side of the frame, lower reinforcement glass is bonded onto the insulation foam. The optical membrane module resistant to the strong vibration can meet the need that membrane wrinkling faults cannot occur at high temperature, and failure frequency of scratch of an optical membrane during vibration can be greatly reduced.

Description

The optical film assembly that against violent vibration is moving
Technical field
The present invention relates to a kind of outdoor liquid crystal display, in particular the moving optical film assembly of a kind of against violent vibration.
Background technology
At present, the use of outdoor liquid crystal display is more and more universal, mainly comprises the liquid crystal display such as airborne and vehicle-mounted.Such liquid crystal display need to be born the vibration of certain magnitude in use conventionally, especially military airborne or carrier-borne liquid crystal display, vibration level in working environment is very large, generally be not less than the acceleration of gravity of 7 times, and direction of vibration is contained X, Y, tri-directions of Z, portioned product even requires, under the acceleration of the acceleration of gravity of 20 times, in X, Y, tri-direction vibration environments of Z, still can work.
Generally by place the mode of optical film assembly before backlight of LCD, realize good display effect, improve light efficiency utilization factor simultaneously.Traditional optical film assembly comprises upper and lower reinforcing white glass, and brightness enhancement film and diffuser between upper and lower reinforcing white glass, apart from liquid crystal display nearer be upper.Four sidewalls of upper and lower reinforcing white glass adopt fluid sealant and upper and lower reinforcing white glass are formed to an annular seal space, and diffuser and brightness enhancement film are housed in annular seal space.
Outdoor liquid crystal display is affected by environment larger, and especially military airborne or carrier-borne liquid crystal display often can be worked in hot environment.Higher environment temperature can significantly improve the temperature of blooming group.Because blooming (referring to diffuser and brightness enhancement film) base material thermal expansivity is larger, high-temperature expansion absolute dimension is larger, and especially large scale liquid crystal display, easily causes the diffuser of blooming group and brightness enhancement film to occur film wrinkle phenomenon.Therefore, when carrying out optical film assembly design, can be by the size relative decrease of film, to guarantee that it does not at high temperature occur film wrinkle fault.As can be seen here, traditional optical film assembly, its blooming parts are being reinforced inside glass in free state, during vibration, between blooming parts (especially large scale product), can produce relative displacement in X, Y-direction, thereby make blooming, become to scratch fault.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of against violent vibration moving optical film assembly, solve optical film assembly and in vibration environment, occur that film scratches failure problems.
The present invention is achieved by the following technical solutions: the present invention includes reinforcing glass, lower reinforcing glass, diffuser, brightness enhancement film and insulation foam, a long limit of described brightness enhancement film is provided with two boss, a minor face of brightness enhancement film is provided with a boss, the structure of diffuser is identical with brightness enhancement film, insulation foam is covered on the surrounding of reinforcing glass, the correspondence position of insulation foam is provided with the opening matching with described boss, it is on glass and be positioned at the framework that surrounds of insulation foam that brightness enhancement film is arranged at reinforcing, boss in brightness enhancement film sticks in long limit of described framework and the opening of adjacent short sides thereof, diffuser is positioned on brightness enhancement film, boss on diffuser sticks in another long limit of described framework and the opening of adjacent short sides thereof, lower reinforcing glass bonding is on insulation foam.
For realizing sealing, the sidewall of described upper reinforcing glass and lower reinforcing glass passes through silicone rubber seal.
Described boss is of a size of long 15 ± 0.2mm, wide 3 ± 0.2mm.
Described insulation foam is provided with double sticky tape, and described lower reinforcing glass sticks on insulation foam by double sticky tape.
The present invention has the following advantages compared to existing technology: the present invention is by the boss of the reserved some of the blooming parts of optical film assembly inside, then it is fixed to reinforcing glass surface by boss by each blooming parts, makes it in vibration processes, be unlikely to produce displacement and occur that blooming scratches fault.Both the demand that does not occur film wrinkle fault under high temperature can be met, the failure-frequency that in vibration processes, blooming scratches can be greatly improved again, particularly to 9 feet * 24 feet this large-sized module.

Embodiment
Below embodiments of the invention are elaborated, the present embodiment is implemented take technical solution of the present invention under prerequisite, provided detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
As shown in Fig. 1~4, the present embodiment comprises reinforcing glass 1, lower reinforcing glass 4, diffuser 3, brightness enhancement film 2 and insulation foam 5, a long limit of described brightness enhancement film 2 is provided with two boss, a minor face of brightness enhancement film 2 is provided with a boss, the structure of diffuser 3 is identical with brightness enhancement film 2, insulation foam 5 is covered on the surrounding of reinforcing glass 1, the correspondence position of insulation foam 5 is provided with the opening 51 matching with described boss, brightness enhancement film 2 is arranged on reinforcing glass 1 and is positioned at the framework that insulation foam 5 surrounds, boss in brightness enhancement film 2 sticks in long limit of described framework and the opening 51 of adjacent short sides thereof, diffuser 3 is positioned on brightness enhancement film 2, boss on diffuser 3 sticks in another long limit of described framework and the opening 51 of adjacent short sides thereof, lower reinforcing glass 4 sticks on insulation foam 5.
