The probability of panel breakage.
Fig. 8 is a kind of flow chart of the manufacturing method of backboard provided in an embodiment of the present invention, as shown in figure 8, this method can
To include:
Step 801 obtains one-time formed back plate main body by preset die, which includes bottom plate, is formed in
The baffle and bar shaped lid on four side of bottom plate, wherein first baffle is formed with the bar shaped lid far from the bottom plate on one side, this
One baffle is formed in the bottom plate for one side of light source to be arranged.
Step 802, at least one end in the bar shaped lid both ends, the width direction along the bar shaped lid is cut,
The length of each cutting seam is equal with the width of the bar shaped lid.
Step 803, by the bar shaped lid, each cutting seam and the region between the bar shaped lid end face, to
Direction far from the bottom plate is turned down, so that the overturning region on the bar shaped lid forms at least one lug, does not turn down area
Domain forms bar shaped cover board.
In conclusion the back plate main body is one-pass molding the embodiment of the invention provides a kind of manufacturing method of backboard, and
Lug is to be formed after cutting to bar shaped lid, therefore reduce the manufacturing cost of backboard, and glue frame is arranged at this
When in back plate main body, the supporting surface of a rectangular-ambulatory-plane can be collectively formed in glue frame with the bar shaped cover board, can make display panel
When being fitted on backlight module, display panel surrounding can uniform stressed, thereby reduce display panel damage probability.
In above-mentioned steps 801, which can be made by sheet metal by the preset die one-pass molding, should
Back plate main body can be as shown in figure 9, include bottom plate 101, the baffle 102 and bar shaped lid 13 for being formed in 101 4 side of bottom plate.
It, can be at least one end in 13 both ends of bar shaped lid, along the width of the bar shaped lid 13 in above-mentioned steps 802
Degree direction is cut, and the length of each cutting seam is equal with the width of the bar shaped lid 13.It is exemplary, it, can be right with reference to Fig. 9
It is cut respectively along cutting line w and cutting line z at the both ends of bar shaped lid 13, it is assumed that cutting line w and 13 left side of bar shaped cover board
Vertical interval between end face is the first spacing d1, the vertical interval between cutting line z and 13 right end face of bar shaped cover board
For the second spacing d2, then the first spacing d1 and second spacing d2 can be equal, formed with guarantee by the bar shaped lid 13
The length of two lugs is equal, wherein the length direction of each lug is parallel with the length direction of the bar shaped lid.
In above-mentioned steps 803, to cutting each on the bar shaped lid 13 seam and between 13 end face of bar shaped lid
Region turned down to the direction far from the bottom plate 101 after, the structure of the backboard can be as shown in figure 5, bar shaped lid in Fig. 9
Overturning region on body 13 forms at least one lug 104 shown in Fig. 5, does not turn down region on bar shaped lid 13 in Fig. 9
Form bar shaped cover board 103 shown in Fig. 5.Wherein, the through-hole in each lug 104 can by the preset die once at
Type can also be reprocessed after backboard demoulding and be formed, and it is not limited in the embodiment of the present invention.
Further, after above-mentioned steps 803, with reference to Fig. 5, can also to the bar shaped cover board 103 close to this at least one
One end of a lug 104 is cut, so that there are gap, examples between the end face and each lug of the bar shaped cover board after cutting
, bar shaped cover board 103 can be cut along cutting line j and k respectively, wherein cutting line j and k is broken line, with reference to figure
7,103 end face of bar shaped cover board after the cutting and there are gap ds between lug.
In conclusion the embodiment of the invention provides a kind of manufacturing method of backboard, by preset die obtain once at
The back plate main body of type, can be at least one end in the back plate main body in bar shaped lid both ends, along the width side of the bar shaped lid
To being cut, then again by each cutting seam and the region between the bar shaped lid end face, to the side far from the bottom plate
To being turned down, so that the overturning region on the bar shaped lid forms at least one lug, region is not turned down and forms bar shaped cover board.
Since the back plate main body is one-pass molding, and lug is to be formed after cutting to bar shaped lid, therefore reduce backboard
Manufacturing cost, and by glue frame be arranged in the back plate main body when, a Back Word can be collectively formed in glue frame with the bar shaped cover board
The supporting surface of shape, when can display panel be fitted on backlight module, display panel surrounding can uniform stressed, and then drop
The probability of low display panel damage.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
