Abstract

The utility model relates to a light conducting plate recovery plane structure, the upper and lower light conducting plates, in which the two sides are warped up, the middle is depressed and deformed are correspondingly covered and overlaid with each other, water liquid is dropped in the location between the upper and lower light conducting plates, then the upper and lower light conducting plates are heavily and horizontally pressed into shape, therefore, the water-absorption recovery property of acryl material of the light conducting plate, the adhesion performance between the upper and lower light conducting plates under the water liquid adhesive force and the horizontal compression can be utilized to achieve the effects of perfectly compressive flatness of the upper and lower light conducting plates.

Description

Light guide plate is recovered planar structure

Technical field

The utility model recovers planar structure relevant for a kind of light guide plate, especially utilize the suction recovery characteristic of its acryl material of light guide plate, and upper and lower light guide plate is fitted mutually because of the adhesion of water liquid, add to give horizontal weight that a kind of light guide plate that flattens effect with the best that reaches upper and lower light guide plate is recovered planar structure.

Background technology

Light guide plate is the strength member of LCD (LCD), especially be used in the LCD of notebook computer, and TaiWan, China is the main production area of global notebook computer, and the annual world market of notebook computer demand probably has more than tens million of; And the main application market of light guide plate is ultra-large type (more than 21 o'clock) LCD TV, large-scale (during 8-20) notebook computer, medium-sized (during 5-7) automobile navigation device, small-sized (during 1-4) Game device.

General light guide plate is made by the acryl material, under normal temperature, because of humidity but, its dual-side is warpage and form the intermediate recess torsional deformation upwards easily, cause be used in establish with module group backlight after, the even diffusion of light can't be reflected, and form bad faulty materials; In order to reply the light guide plate of this warpage, usually with the light guide plate storehouse weight of warpage even control with humiture, yet existing answer mode but still has following shortcoming, suddenly waits to improve;

1. existing answer mode replys the light guide plate of warpage for the required consumed time of non-defective unit is quite long, is not inconsistent economic benefit.

2. existing answer mode is quite low for the ratio of non-defective unit with the light guide plate answer of warpage.

3. existing answer mode because the light guide plate of warpage is replied to the ratio of non-defective unit is quite low, is chosen and is carried as choosing so need expend a lot of manpowers, and carrying then causes the scratch or the unfilled corner phenomenon of light guide plate often easily again, additionally increases a lot of scrap cost.

4. existing answer mode because the light guide plate of warpage is replied to the required consumed time of non-defective unit is quite long, need take very big space so will place the light guide plate of this warpage, increases a lot of space costs.

So in view of this inventor adheres to relevant industries practical design and manufacturing experience for many years, is studied improvement at existing disappearance, provide a kind of light guide plate to recover planar structure, in the hope of improving existing all disappearances fully.

Summary of the invention

The purpose of this utility model is to provide a kind of light guide plate to recover planar structure, to overcome the defective of existing structure.

The purpose of this utility model is to realize like this, a kind of light guide plate is recovered planar structure, establish light guide plate earlier, this time light guide plate is dual-side make progress warpage and intermediate recess, and on following light guide plate, drip and establish water liquid, foldedly on following light guide plate again establish light guide plate on, and go up that light guide plate is dual-side downsagging and intermediate drum is protruding, above last light guide plate, install weight.In view of the above, utilize the suction recovery characteristic of its acryl material of light guide plate, reach upper and lower light guide plate and fit mutually, add to give horizontal weight, flatten effect with the best that reaches upper and lower light guide plate because of the adhesion of water liquid.

Structure of the present utility model is from the above mentioned formed as can be known, the utlity model has following advantage:

1. recovery planar structure of the present utility model is quite simple, and it is not only convenient but also quick to operate.

2. recovery planar structure of the present utility model, its answer is shortened much with respect to existing answer mode for the required consumed time of non-defective unit.

3. recovery planar structure of the present utility model, its answer improves much with respect to existing answer mode for the ratio of non-defective unit.

4. recovery planar structure of the present utility model, its reply for the ratio of non-defective unit and all more existing answer mode of time come good, therefore can reduce the cost of a dead lift greatly, simultaneously, few carrying also can reduce the generation of scratch or unfilled corner.

5. recovery planar structure of the present utility model, its answer is good for the ratio of non-defective unit and all more existing answer mode of time, therefore can save the space of stacking light guide plate.

6. the utility model is owing to utilize the suction recovery characteristic of its acryl material of light guide plate, and upper and lower light guide plate fits together mutually because of the adhesion of water liquid, in recover on the plane effect quite good and also to consume cost quite cheap.

Embodiment

At first, see also Fig. 1～shown in Figure 2, a kind of light guide plate of the present utility model is recovered planar structure, mainly be on dual-side makes progress the following light guide plate 2 of warpage and intermediate recess torsional deformation, drip and establish water liquid 3, the folded thereon again light guide plate 1 of establishing, last light guide plate 1 is dual-side downsagging and intermediate drum convex twisting song is out of shape shape, installs weight then and give horizontal weight and form above last light guide plate 1;

This upper and lower

light guide plate

1,2 is to make by comprising the acryl material, utilizes its surface to have the water of absorption liquid 3 characteristics, and can produce swelling after absorbing water liquid 3, simultaneously, gives horizontal weight so that upper and lower

light guide plate

1,2 reaches the recovery plane effect.

When implementing to use, see also Fig. 1～shown in Figure 2, at normal temperatures, earlier dual-side is made progress warpage and the following light guide plate 2 of intermediate recess torsional deformation is seated on the platform 4, again with dual-side also warpage and the last light guide plate 1 of intermediate recess torsional deformation spins upside down upwards, make it become arc lid shape, and it is corresponding superimposed on following light guide plate 2, make, following

light guide plate

1,2 correspondences trim, then last, following light guide plate 1, splash into water liquid 3 between 2, make, following
