Description
FIELD
[0001] The subject matter generally relates to structure of a
display device.
BACKGROUND
[0002] A television includes a display screen and a back plate. The
display screen and the back plate may be connected by deformable
hooks or screw locks. However, such hooks on the outer frame may
easily break during assembly and disassembly, and the hooks on the
outer frame need to be replaced when they are broken. Moreover,
broken screw locks may fall inside the interior of the television,
where they can cause damage to the television.
[0003] Thus, there is room for improvement in the art.

and a side frame 12 connected to the inwardly extending frame 11.
The inwardly extending frame 11 is perpendicular to the side frame
12.
[0015] In at least one embodiment, the inwardly extending frame 11
and the side frame 12 are integrally formed together. In another
embodiment, the side frame 12 can be connected to the inwardly
extending frame 11 by screws or adhesive.
[0016] The side frame 12 includes a side surface 121, the side
surface 121 is perpendicular to the inwardly extending frame
11.
[0017] The outer frame 10 further includes a fixture block 13. The
fixture block 13 is formed on the side surface 121 of the side
frame 12.
[0018] The fixture block 13 is substantially T-shaped. The fixture
block 13 includes a first fixture portion 131 and a second fixture

adhesive.
[0022] The main board 21 is perpendicular to the side frame 12. The
side board 22 is parallel to the side frame 12.
[0023] The backplane 20 further includes a T-shaped groove 23. The
T-shaped groove 23 extends through the side board 22. The T-shaped
groove 23 is substantially T-shaped. The T-shaped groove 23
includes a first groove 231 and an inwardly extending groove 232.
The second groove 232 is perpendicular to the first groove 231. The
second groove 232 communicates with the first groove 231. The first
groove 231 and the second fixture portion 132 extend in the same
direction.
[0024] The first groove 231 has a length/width that is greater than
or equal to a length/width of the second fixture portion 132. In at
least one embodiment, the length/width of the first groove 231 is
slightly greater than the length/width of the second fixture
portion 132.
[0025] The inwardly extending groove 232 has a width that is
greater than or equal to a thickness of the first fixture portion
131. The width of the inwardly extending groove 232 is less than a
length of the second fixture portion 132. In at least one
embodiment, the width of the inwardly extending groove 232 is
slightly greater than the width of the first fixture portion 131.
The width of the inwardly extending groove 232 is less than a
length of the second fixture portion 132. The second fixture
portion 132 can enter into the first groove 231. The first fixture
portion 131 can be moved while in the inwardly extending groove
232.
[0026] When the second fixture portion 132 is moved to the end of
the inwardly extending groove 232 that is spaced furthest away from
the first groove 231, the second fixture portion 132 engages with
the two sides of the inwardly extending groove 232. Thereby, the
side board 22 and the side frame 12 can be connected together.
[0027] When the second fixture portion 132 is moved to the first
groove 231, the first fixture portion 131 and the second fixture
portion 132 can be taken out of the first groove 231. Thereby, the
side board 22 and the side frame 12 can be disassembled.
[0028] The first fixture portion 131 has a length that is greater
than or equal to a thickness of the side board 22. In at least one
embodiment, the length of the first fixture portion 131 is slightly
greater than the thickness of the side board 22.
[0029] The middle frame 30 is formed on the main board 21. The
middle frame 30 is parallel to the side board 22.
[0030] The display screen 40 is formed on the end of the middle
frame 30 that is spaced furthest away from the main board 21.
[0031] The display screen 40 includes a display surface 41. The
display surface 41 is spaced furthest away from the main board 21.
The display surface 41 contacts the inwardly extending frame
11.
[0032] In another embodiment, the middle frame 30 in FIG. 2 can be
omitted from the display device 100. The display screen 40 can then
be formed on the inwardly extending frame 11.
[0033] The display screen 40 can be a liquid crystal display or a
plasma panel. In at least one embodiment, the display screen 40 is
a liquid crystal display.
[0034] The optical module 50 provides light to illuminate the
display screen 40.
[0035] The optical module 50 is fixed on the main board 21 and
faces the display screen 40.
[0036] The middle frame 30 is located between the optical module 50
and the side board 22.
[0037] In at least one embodiment, assembly of the display device
100 includes one or more of the following steps. Firstly, the outer
frame 10 is placed above the backplane 20 and driven to the side
frame 12 to allow inserting the fixture block 13 in the T-shaped
groove 23. The outer frame 10 is moved to the end of the inwardly
extending groove 232 that is spaced furthest away from the first
groove 231, the second fixture portion 132 engages the two sides of
the inwardly extending groove 232. Thereby, the side board 22 and
the side frame 12 can be connected together. Secondly, the middle
frame 30 and the optical module 50 are formed on the main board 21.
The display screen 40 is formed on the middle frame 30.
[0038] In another embodiment, assembly of the display device 100
includes one or more of the following steps. Firstly, the middle
frame 30 and the optical module 50 are formed on the main board 21.
The display screen 40 is formed on the middle frame 30. Secondly,
the outer frame 10 is placed above the backplane 20 and driven to
the side frame 12 to allow inserting the fixture block 13 into the
T-shaped groove 23, then the outer frame 10 is moved to the end of
the inwardly extending groove 232 that is spaced furthest away from
the first groove 231, the second fixture portion 132 engages the
two sides of the inwardly extending groove 232. Thereby, the side
board 22 and the side frame 12 can be connected together.
[0039] Disassembly of the display device 100 includes one or more
of the following steps. Firstly, the outer frame 10 is pushed until
the fixture block 13 is released from the inwardly extending groove
232 and enters into the first groove 231. Secondly, the outer frame
10 is pulled away from the side board 22 until the fixture block 13
clears the first groove 231.
[0040] With the above configuration, the display device 100 can be
assembled and disassembled easily, so the assembly and disassembly
of the display device 100 can be done quickly and without tools.
The display device 10 prevents opportunities for debris from being
introduced inside the interior of the television.
[0041] The embodiments shown and described above are only examples.
Many details are often found in the art such as the other features
of the display device. Therefore, many such details are neither
shown nor described. Even though numerous characteristics and
advantages of the present technology have been positioned forth in
the foregoing description, together with details of the structure
and function of the present disclosure, the disclosure is
