container and are unpacked, the water mist or the water drops are
frequently found generated inside the wrapping films and inside the
boxes.
[0004] Regarding the above issue, the current general solution is
to dispose desiccants around the packaging boxes. Though the
desiccant has a certain of water absorption effect, it can only
absorb the water around the liquid crystal panel, and cannot absorb
the water on the surfaces of the liquid crystal panel. Besides, for
reducing the impact force among the liquid crystal panel, the
buffer materials would be disposed among the liquid crystal panel.
The buffer materials are generally the low water absorption of
materials, so the water mist on the liquid crystal panel would be
kept all the time and cannot be absorbed by the desiccants.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0021] The specific structural and functional details disclosed
herein are only representative and are intended for describing
exemplary embodiments of the disclosure. However, the disclosure
can be embodied in many forms of substitution, and should not be
interpreted as merely limited to the embodiments described
herein.
[0022] Referring to FIG. 1, in this embodiment, the spacing pad
with water absorption function for liquid crystal panel comprises a
first buffer layer 20, a second buffer layer 30 and a water
absorption layer 10. The first buffer layer 30 and the second
buffer layer 30 are disposed opposite to each other. The water
absorption layer 10 is disposed between the first buffer layer 20
and the second buffer layer 30. The first buffer layer 20 is formed
with multiple first water absorption holes 21 thereon, and the
second buffer layer 30 is formed with multiple second water
absorption holes 31 thereon. The multiple first water absorption
holes 21 and the multiple second water absorption holes 31 are both
applied for exposing the water absorption layer 10. When the
spacing pad is interposed between two liquid crystal panel, the
water on the surfaces of the two liquid crystal panel would be
entering the water absorption layer 10 through the multiple first
water absorption holes 21 and the multiple second water absorption
holes 31 separately, to guarantee the whole surfaces of the liquid
crystal panel being dry.
[0023] As a preferred embodiment, the first buffer layer 20 and the
second buffer layer 30 are made of expandable polyethylene (EPE).
This kind of material with good buffer performance can reduce
effectively the impact force among the liquid crystal panel and
prevent the liquid crystal panel from breaking. Surely, in other
embodiments, the first buffer layer 20 and the second buffer layer
30 can be made of expanded polypropylene (EPP). The water
absorption layer 10 is made of the high water-absorbent resin
material. The high water-absorbent resin material with good water
absorption and high water-retention would not release absorbed
water when the water absorption layer is extruded. Besides, the
high water-absorbent resin material has good elasticity after
absorbing water, so during the transport of the liquid crystal
panel the water absorption layer 10 can still provide a certain of
buffer effect.
[0024] In specific, an inner sidewall of the first water absorption
hole 21 is inclined, and an angle between the inner sidewall of the
first water absorption hole 21 and a bottom of the first water
absorption hole 21 is an obtuse angle. Namely, the first water
absorption hole 21 is a tapered hole, and the diameter of one end
of the first water absorption hole 21 far away the water absorption
layer 10 is larger than the diameter of the other end of the first
water absorption hole 21 close to the water absorption layer 10.
Thus, the inner sidewall of the first water absorption hole 21 has
a certain of slope to have the water on the surfaces of the liquid
crystal panel flow easily into the water absorption layer 10. The
larger opening end of the first water absorption hole 21 is
attached to the liquid crystal panel for contacting larger area of
the liquid crystal panel, thereby beneficial for absorbing more
water and further guaranteeing the whole structure stability of the
spacing pad.
[0025] Further, for guaranteeing both two sides of the spacing pad
have good water absorption, an inner sidewall of the second water
absorption hole 31 is inclined correspondingly, and an angle
between the inner sidewall of the second water absorption hole 31
and a bottom of the second water absorption hole 31 is an obtuse
angle. Namely, the second water absorption hole 31 is a tapered
hole, and the diameter of one end of the second water absorption
hole 31 far away the water absorption layer 10 is larger than the
diameter of the other end of the second water absorption hole 31
close to the water absorption layer 10. As a preferred embodiment,
each one of the multiple first water absorption holes 21 is facing
the corresponding one of the multiple second water absorption holes
31. It should be explained, the inclined angles of the inner
sidewalls of the first water absorption hole 21 and the second
water absorption hole 31 can be set artificially.
[0026] In specific, as shown in FIG. 3, the cross-sectional shape
of the first water absorption hole 21 and/or the second water
absorption hole 31 along the direction parallel to the water
absorption layer 10 is preferably a circle. Surely in other
embodiments, as shown in FIG. 2, the cross-sectional shape can also
be, but not limited to, a hexagon, and can be other polygon shapes
or honeycomb shape.
[0027] Further, the multiple first water absorption holes 21 and
the multiple second water absorption holes 31 are separately
arranged in multiple columns and multiple rows, for guaranteeing
the contact parts, between the first water absorption hole 21 and
the liquid crystal panel, or between the second water absorption
hole 31 and the liquid crystal panel, are distributed evenly,
thereby beneficial for the water absorption layer 10 absorbing
completely the water on the liquid crystal panel.
[0028] In other embodiments, as shown in FIG. 4, the first water
absorption holes 21 are long bar shaped holes extending along the
width direction of the first buffer layer 20, and the multiple
first water absorption holes 21 are arranged at a fixed interval to
each other along the length direction of the first buffer layer 20.
Correspondingly, the second water absorption holes 31 are long bar
shaped holes extending along the width direction of the second
buffer layer 30, and the multiple second water absorption holes 31
are arranged at a fixed interval to each other along the length
direction of the second buffer layer 30. Thus, the contact areas,
between the first water absorption holes 21 and the liquid crystal
panel, and between the second water absorption holes 31 and the
liquid crystal panel, are individually increased, thereby
beneficial for absorbing more water.
[0029] As shown in FIG. 5, the difference between the spacing pad
with water absorption function for liquid crystal panel in this
embodiment and the spacing pad in the first embodiment is that the
multiple first water absorption holes 21 and the multiple second
water absorption hole 31 are staggered mutually. Namely, the
projections of the first water absorption holes 21 on the water
absorption layer 10 and the projections of the second water
absorption hole 31 on the water absorption layer 10 are not
overlapped, so the water flowing through the first water absorption
holes 21 and the second water absorption holes 31 are absorbed by
different parts of the water absorption layer 10,thereby beneficial
for the water diffusion in the water absorption layer 10 to promote
the water absorption of the water absorption layer 10.
[0030] The present invention provides a spacing pad with water
absorption function for liquid crystal panel. The first buffer
layer, the water absorption layer and the second buffer layer are
arranged in a stacked structure, and the first buffer layer and the
second buffer layer are made with water absorption holes thereon,
for providing the spacing pad with buffer effect and at the same
time being able to absorb the water on the liquid crystal
panel.
[0031] The foregoing contents are detailed description of the
disclosure in conjunction with specific preferred embodiments and
concrete embodiments of the disclosure are not limited to these
descriptions. For the person skilled in the art of the disclosure,
without departing from the concept of the disclosure, simple
deductions or substitutions can be made and should be included in
the protection scope of the application.
