Liquid crystal module
Technical Field
The utility model relates to a technical field of display, in particular to liquid crystal module.
Background
As shown in fig. 1, the conventional liquid crystal module includes a backlight module 7, a liquid crystal panel 6 fixed on the backlight module 7, a printed circuit board 5 located on a side surface of the liquid crystal panel 6, and a flexible printed circuit board 3 connecting the printed circuit board 5 and the liquid crystal panel 6. Wherein, one end of the flexible printed circuit board 3 is fixed on the printed circuit board 5, and the other end of the flexible printed circuit board 3 is fixed on the liquid crystal panel 6; one side of the backlight module 7 is provided with two fixing ears 1 protruding outwards, and the two fixing ears 1 are respectively positioned at the left end and the right end of the printed circuit board 5; the printed circuit board 5 is fixed on the fixing lug 1 by a screw 2. The flexible printed circuit board often has a camber phenomenon during the production process, which causes the camber of the flexible printed circuit board to have two reasons: (1) the deformation of the fixing ears causes relative displacement between the printed circuit board and the liquid crystal panel, thereby causing poor arching of the flexible printed circuit board; (2) the screw fixing screw of the printed circuit board is not locked tightly, so that the printed circuit board moves, and the flexible printed circuit board is arched.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a liquid crystal module can prevent that flexible printed circuit board from taking place to arch up.
The utility model provides a liquid crystal module, which comprises a backlight module, a liquid crystal panel fixed on the backlight module, a printed circuit board positioned on the side surface of the liquid crystal panel, a first flexible printed circuit board positioned on the left side of the printed circuit board and a second flexible printed circuit board positioned on the right side of the printed circuit board; one end of the first flexible printed circuit board is fixed on the printed circuit board, and the other end of the first flexible printed circuit board is fixed on the liquid crystal panel; one end of the second flexible printed circuit board is fixed on the printed circuit board, and the other end of the second flexible printed circuit board is fixed on the liquid crystal panel; the two leveling structures are respectively covered on the first flexible printed circuit board and the second flexible printed circuit board; at least three fixing ears protruding outwards are arranged on one side of the backlight module, wherein two fixing ears are respectively positioned on the left side of the first flexible printed circuit board and the right side of the second flexible printed circuit board, and at least one fixing ear is positioned between the first flexible printed circuit board and the second flexible printed circuit board; the printed circuit board and the two leveling structures are fixed on the fixing ears.
Further, an insulating material is arranged on the outer surface of the leveling structure.
Furthermore, one end of the leveling structure close to the backlight module is bent upwards.
Further, the shape of the leveling structure is rectangular or circular or elliptical or polygonal.
Furthermore, a first through hole is formed in the printed circuit board, a second through hole is formed in the leveling structure, and screws sequentially penetrate through the first through hole and the second through hole to fix the printed circuit board and the leveling structure on the fixed ears.
Further, the shape of the fixing ear is straight or bent or the combination of straight and bent.
The utility model discloses an add two flattening structures on first flexible printed circuit board and second flexible printed circuit board, increase the quantity of fixed ear on backlight unit to on being fixed in fixed ear with the flattening structure, can prevent that flexible printed circuit board from taking place to arch up.
