particularly to a frame structure for mounting a liquid crystal
display panel, and the frame is made by combining each side of the
frame by a bonding technique to avoid wasting raw materials and
lower costs.
[0003] 2. Description of the Related Art
[0004] As LCD panels are used extensively, traditional cathode ray
tube monitors are upgraded to the liquid crystal display
technology. LCD panels emphasize on their lightweight, compactness
and high resolution which are widely welcome by consumers. However,
the price of LCD panels is high, since the light and compact
structure of the LCD panel contains small components, and materials
are wasted during the manufacturing process, and these cause a high
cost. Referring to FIG. 1 for a frame 10 for supporting and
mounting an LCD panel, the frame 10 is comprised of two long sides
and two short side integrally combined into the frame 10, and the
hollow portion at the middle of the frame 10 is evacuated by
equipments, and thus causing a waste of raw materials. At the
present stage, the price of raw materials remains very high, and
the cost incurred is amazingly high, and all these costs will be
reflected on the products or finished goods, so that LCD TV and LCD
panels come with a very high price, and it is a subject for
manufacturers to effectively avoid the foregoing shortcomings and
make improvements.

and applicability.
[0007] The frame structure for mounting a liquid crystal display
panel of the present invention is characterized in that each side
of the frame structure is shaped and bonded by a bonding technique
and the bonding sides of the frame can be jointed, embedded or
latched by different kinds of structures.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0020] Referring to FIG. 2 for a frame structure for mounting a
liquid crystal display panel in accordance with the present
invention, the frame 20 is comprised of two long sides 21 and two
short sides 22, and a 45-degree diagonal is formed at connecting
ends 211, 221 of the long side 21 and the short side 22, and a
rectangular frame is formed by connecting the two long sides 21 and
two short sides 22 through the connecting ends 211, 221, and a
connecting base 23 disposed separately at the four corners of the
frame 20 is applied with a bonding technique to constitute the
whole structure of the frame 20 as shown in FIG. 3.
[0021] The connecting base 23 has a top 231 and two adjacent
longitudinal sides 232, such that after the two long sides 21 and
the two short sides 22 of the frame 20 are combined to form a
rectangular frame, a connecting base 23 disposed separately at four
corners of the frame can be used for attaching the top 231 and the
longitudinal sides 232 of the connecting base 23 to the lap joint
position of the long side 21 and the short side 22 of the frame 20
by a bonding technique to form an internal angle, so that the
bonded area can be larger to enhance the boding strength.
[0022] Referring to FIG. 4 for a frame structure for mounting a
liquid crystal display panel in accordance with the present
invention, the frame 20 is comprised of two long sides 21 and two
short sides 22, and the long sides 21 and the short sides 22 form
connecting ends 211, 221 to lap and connect the two long sides 21
and the two short sides 22 into a rectangular frame by using the
connecting ends 211, 221, and a bonding technique is adopted at the
connecting ends 211, 221 to form the whole structure of the frame
20 as shown in FIGS. 5 and 6.
[0023] The connecting end 211 disposed separately at both ends of
the long side 21 is substantially in an L-shape right angle, and
the connecting end 221 disposed separately at both ends of the
short side 22 forms a first lap joint 222 substantially in a
step-shape and disposed at the top of the short side 22, and a
second lap joint 223 substantially bent in a right angle and
extended from a longitudinal side proximate to the first lap joint
222. When the connecting ends 211 of the two long sides 21 are
engaged with the connecting ends 221 of the short side 22, the
first lap joint 222 of the short side 22 is lapped onto the bottom
of the top of the connecting end 211 of the long side 21 and the
second lap joint 223 of the short side 22 is lapped onto the
internal side of the longitudinal side of the connecting end 211 of
the long side 21. Due to the step-shape design of the first lap
joint 222, its drop is precisely equal to the thickness of the top
of the long side 21, the long sides 21 and the short sides 22 of
the rectangular frame so formed after the lap connection by a
bonding technique can be fixed by the connecting ends 211, 221 and
the first lap joint 222 and the second lap joint 223 of the short
side 22, so as to enhance the bonding strength and reduce the
damage produced by transversal and longitudinal stresses. In the
meantime, the connecting ends 211, 221 formed after lapping the
long side 21 with the short side 22 are flat and smooth without
causing any inference by protrusions or recessions, so as to
constitute the whole structure of the frame 20 as shown in FIG.
5.
[0024] The connecting end 211 at an end of the long side 21 uses a
first lap joint 222 of the connecting end 221 at an end of the
short side 22 to lap with the bottom of the top of the connecting
end 211 at an end of the long side 21, and the second lap joint 223
of the connecting end 221 is lapped onto the internal side of the
longitudinal side of the connecting end 211 at an end of the long
side 21. The connecting end 211 at another end of the long side 21
uses the first lap joint 222 of the connecting end 221 at another
end of the short side 22 to lap with the bottom of the top of the
connecting end 211 at another end of the long side 21, and the
second lap joint 223 of the connecting end 221 is lapped onto the
external side of the longitudinal side of the connecting end 211 at
another end of the long side 21. In the meantime, a bonding
technique is adopted, such that a diagonal of the whole structure
of the frame 20 is folded, and another diagonal of the second lap
joint 223 of the short side 22 is hooked at the external side of
the longitudinal side of the long side 21 as shown in FIG. 6 to
enhance the strength for bonding the long sides 21 and the short
sides 22 of the frame 20.
[0025] Referring to FIG. 7 for a frame structure for mounting a
liquid crystal display panel in accordance with the present
invention, the frame 20 is comprised of two long sides 21 and two
short sides 22, and the long sides 21 and the short sides 22 form
connecting ends 211, 221 to lap and connect the two long sides 21
and the two short sides 22 into a rectangular frame by using the
connecting ends 211, 221, and a bonding technique is adopted at the
connecting ends 211, 221 to form an overall structure of the frame
20 as shown in FIG. 8.
[0026] The connecting end 211 disposed separately at both ends of
the long side 21 is bent into a right angle and extended from the
top of the connecting end 211 to form a lap joint 212, and the
lateral side of its longitudinal side forms an interval with the
lap joint 212. The step-shape first lap joint 222 is formed at the
top of the connecting end 221 disposed separately at both ends of
the short side 22, and the first lap joint 222 is bent into a right
angle downwardly to form the second lap joint 223, and a junction
224 is bent into a right angle and extended from a longitudinal
side proximate to the first lap joint 222. The first lap joint 222
and the second lap joint 223 form an interval with the longitudinal
side of the short side 22, and the interval is precisely equal to
the thickness of the lap joint 212 of the connecting end 211
disposed separately at both ends of the long side 21. The lateral
side of the longitudinal side of the long side 21 and the lap joint
212 form an interval precisely equal to the bent and extended
distance of the junction 224 of the short side 22. When the
connecting ends 211 of the two long sides 21 are connected to the
connecting ends 221 of the two short sides 22, the lap joint 212 of
the connecting end 211 disposed separately at both ends of the long
side 21 is embedded into the interval between the first lap joint
222 and the second lap joint 223 of the connecting end 221 at both
ends of the short side 22 and the longitudinal side of the short
side 22. In the meantime, the first lap joint 222 of the short side
22 is lapped onto the bottom of the top of the connecting end 211
of the long side 21, its second lap joint 223 is lapped onto the
connecting end 211 at the internal side of the longitudinal side of
the long side 21, and its junction 224 is precisely connected to
the interval formed between the lateral side of the longitudinal
side of the long side 21 and the lap joint 212. The drop of the
step-shape design of the first lap joint 222 of the short side 22
is precisely equal to the thickness of the top of the long side 21,
so as to provide a smooth and flat connection. In the meantime, a
bonding technique is applied to enhance the bonding strength and
reduce the damages produced by the transversal and longitudinal
stresses and constitute an overall structure of the frame 20 as
shown in FIG. 8.
[0027] Referring to FIG. 9 for a frame structure for mounting a
liquid crystal display panel in accordance with the present
invention, the frame 20 is comprised of two long sides 21 and two
short sides 22, and the long sides 21 and the short sides 22 form
connecting ends 211, 221 to lap and connect the two long sides 21
and the two short sides 22 into a rectangular frame by using the
connecting ends 211, 221, and a bonding technique is adopted at the
connecting ends 211, 221 to form the whole structure of the frame
20 as shown in FIG. 10.
[0028] The top of connecting end 211 disposed separately at both
ends of the long side 21 forms a lap joint 212 in the shape of a
long hole, and its longitudinal side forms a U-shape indent and
shallow-trench lap joint 213 and an inwardly drawn interval formed
at the outer lateral side of the lap joint 212. The top of the
connecting end 221 disposed separately at both ends of the short
side 22 forms a first lap joint 222, and a second lap joint 223
substantially bent into a right angle and extended from a
longitudinal side proximate to the first lap joint 222. When the
connecting ends 211 of the two long sides 21 are connected to the
connecting ends 221 of the two short sides 22, the lap joints 212,
213 of the connecting ends 211 at both ends of the long side 21 are
connected flatly with a first lap joint 222 and a second lap joint
223 of the connecting ends 221 at both ends of the short side 22,
so as to achieve a smooth and flat connection without any interface
of protrusions or recessions on the surface and enhance the bonding
strength and reduce the damage produced by the transversal and
longitudinal stresses and constitute the overall structure of the
frame 20 as shown in FIG. 10. The design of this embodiment can
avoid interference caused by components other than the screen or
LCD panel 30.
[0029] Any one of the foregoing embodiments can be used together
with an LCD panel 30 as shown in FIG. 11 and can be designed to
meet the structural requirements of the frame of the LCD panel for
combining, supporting, fixing and positioning the LCD panel 30. In
the meantime, such arrangement also achieves the effects of high
productivity, strength and utility rate and also avoids wasting raw
materials and controls costs.
[0030] In summation of the above description, the frame structure
for mounting a liquid crystal display panel in accordance with the
present invention definitely achieves the expected objective and
provides an improved frame structure to enhance the performance
over the prior art. The invention further complies with the patent
application requirements and is duly filed for the patent
application.
[0031] While the invention has been described by means of a
specific numerous modifications and variations could be made
thereto by those skilled in the art without departing from the
scope and spirit of he invention set forth in the claims.
