Abstract

The utility model relates to a protection device of a liquid crystal panel mould set. The front of a liquid crystal panel mould set is provided with a glass plate. The glass plate and the liquid crystal panel mould set are coated and assembled by a frame, which prevents an upper light polarized sheet of the liquid crystal panel mould set from being damaged. In addition, an optical film can be sputtered on the glass plate, and because the glass plate has the temperature resistance, when the optical film is sputtered, the convenience and the reliability can be obtained, which leads a liquid crystal display to have good visibility.

Description

The protective device of liquid crystal panel module

Technical field

The utility model refers to the protective device of the true tool protection of a kind of last polaroid to liquid crystal panel module front side effect especially relevant for a kind of protective device of liquid crystal panel module.

Background technology

But the rough segmentation of liquid crystal panel module primary structure becomes panel and module two large divisions backlight, the panel molding comprises the ITO electro-conductive glass, liquid crystal, alignment film, colored filter, polaroid, drive IC etc., module backlight then comprises fluorescent tube, the blooming of light guide plate and each style, the performance of the whole optics of this liquid crystal panel module is to be subjected to all material reciprocal effects in the module, wherein polaroid is in making liquid crystal panel module process, in each becomes alternate directions to insert with a slice up and down, in order to show caption-pattern, and existingly commonly when being assembled into the display finished product go up the polaroid scratch, the replacing that should go up polaroid needs special-purpose board to remove and attach, and also need the decomposition of liquid crystal panel module is expended man-hour, and might injure IC and module backlight in decomposable process.So see also Fig. 1, shown in Figure 2, general liquid crystal panel module 11 is in assembling often in framework 12 outsides, the fender 13 of additional a slice PET (Polyethylene-Terephthalate) material, used with the last polaroid 14 that is provided as protection liquid crystal panel module 11 front sides; So; PET (Polyethylene-Terephthalate) material that this fender 13 is adopted is a kind of high molecular polymer, and tool is difficult for decomposability, easily causes to cause environmental pollution; environmental consciousness surging today, it is required to be that the fender 13 of material has not met the current situation with PET.

Seeing also Fig. 3, shown in Figure 4, be another known example, is the fender 23 that hangs a slice glass material in shell 25 outsides of liquid crystal panel module 21 frameworks 22, in order to protect this liquid crystal panel module 21 front side polaroids 24; So, the setting of hanging type according to this, this fender 23 has the anxiety that drops, and cause order and can't protect polaroid 24 not to be damaged really, and also quite inharmonious in its overall appearance.

Summary of the invention

The purpose of this utility model is to provide a kind of protective device of liquid crystal panel module, in liquid crystal panel module the place ahead one glass plate is set, and utilize framework that glass plate and liquid crystal panel module coating group are established, to protect the last polaroid of this liquid crystal panel module, it is impaired that it is avoided; Moreover, by the resistant to elevated temperatures characteristic of glass material, when sputter blooming on glass plate, have more reliability and convenience, in order to improve the visuality of this LCD.

Embodiment

For the technological means that makes the utility model utilization with reach effect and be easy to understand that conjunction with figs. is described as follows:

At first, see also Fig. 5～shown in Figure 7, the protective device of liquid crystal panel module of the present utility model, be that last polaroid 32 the place aheads set in liquid crystal panel module 31 front sides are provided with glass plate 33, be provided with framework 34 in these glass plate 33 outsides, utilize framework 34 that this glass plate 33 and liquid crystal panel module 31 coating groups are established, thus, make glass plate 33 be protected the last polaroid 32 of these liquid crystal panel module 31 front sides not to be damaged really; Moreover, can be on this glass plate 33 sputter blooming 35, this blooming 35 can increase brightness, uniformity coefficient and the contrast etc. of liquid crystal panel module, characteristic by the glass material heatproof, and have more convenience and reliability when making on this glass plate 33 sputter blooming 35, improve the visuality of this LCD in view of the above.

By said structure as can be known the utility model and the known following advantage of true tool of comparing:

1. glass plate of the present utility model is to be located at before the liquid crystal panel module, and is hard by this glass material matter Characteristic, can for giving the better protection effect of upper polaroid of this liquid crystal panel module front side, continue Glass plate arranged outside framework is established glass plate and liquid crystal panel module coating group, so this glass plate is not Cause the anxiety that drops, suffered the damage such as scratch so that certain protection is should upper polaroid unlikely.

2. though glass plate of the present utility model is difficult for decomposing corrupt characteristic with the PET material with tool, the glass of so scrapping can supply recycling, glassware after this reclaims is behind classification, fragmentation, decon, send into again in the glass-melting furnace to make new glassware, use these two defective materials that reclaim again and can more save the energy, reduce air pollution than make glass of raw material, water pollutes and directly reduces the environmental benefit of the tool resources such as load of landfill site.

3. the temperature tolerance of glass plate of the present utility model institute tool, higher than plastic material, so when the sputter blooming, have more the convenience reliability, in view of the above, can improve brightness, uniformity coefficient and the contrast etc. of liquid crystal panel module, to increase the visuality of this LCD.

4. glass plate of the present utility model only must be removed framework when if damage is arranged, and changes glass plate and gets final product, and is quite convenient.

Claims

1. the protective device of a liquid crystal panel module, it is characterized in that: in liquid crystal panel module the place ahead glass plate is set, at glass plate arranged outside framework, framework is established glass plate and liquid crystal panel module coating group, protects the last polaroid of this liquid crystal panel module.
