Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 2 ~ Fig. 3 is the utility model embodiment attached drawing.The utility model embodiment provides a kind of display module, including aobvious
The side of display screen and backlight module, display screen has COF flexible circuit board.COF flexible circuit board includes flexible base board 21 and position
In the control chip 22 on flexible base board；The fold of flexible base board 21 is in bending, including the non-flex area close to display screen side
211, the fold area 213 far from non-flex area and the flex area 212 between non-flex area and fold area.
It controls chip 22 and is located at fold area 213, and turn down a part in area and the back side connection of backlight module.Specifically,
Turning down area 213 has interconnecting piece, the back side connection of interconnecting piece and backlight module；Turning down area 213 also has encapsulation part, controls chip
22 are located at the encapsulation part in fold area 213.And it controls chip 22 and is located at non-flex area 211, flex area 212, turns down the interior of area 213
Side.
It is also formed with receiving portion 50 between non-flex area 211, flex area 212, fold area 213 and backlight module, is controlled
Chip 22 is located in receiving portion 50.
By the way that the setting of chip 22 will be controlled between non-flex area 211, flex area 212, fold area 213 and backlight module
Receiving portion 50 in, allow control chip 22 it is built-in.Avoid control chip 20 it is exposed and by damage.
Further, the backlight module includes frame 31 and back light member 32, and back light member 32 includes multiple luminous two
Pole pipe, flexible circuit board 39.Multiple light emitting diodes are mounted on the inside of frame 31.Frame 31 is including bottom wall 311 and surrounds institute
The side wall 312 of bottom wall is stated, the bottom wall 311 is located at the side for deviating from display screen, and bottom wall 311 and side wall 312 form semiclosed
The frame of formula, the opening of frame 31 is towards display screen.312 top of side wall of frame 31 is fixedly connected with display screen.On side wall 312
It also is extended with flanging 313 to the direction of flex area 212, at least part of flanging 313 is located in receiving portion 50；In some implementations
In example, flanging 313 and side wall 312 are in a certain angle.Preferred embodiment is that flanging 313 and side wall 312 are in 90 degree of angles, bottom
Wall 311, side wall 312, flanging 313 are substantially Z-shaped.There is spacing, control between flanging 313 and the fold area 213 of flexible base board
Coremaking piece 22 is located between flanging 313 and the fold area 213 of flexible base board 21.Preferably, it controls between chip 22 and flanging 313
With gap.
There is no the support glue frame 34 in traditional design (Fig. 1) between side wall 312 and light emitting diode, in traditional design
In, since the side wall of frame 31 is relatively thin, thus the structural strength of 31 side wall of frame is lower, and support 34 material of glue frame is generally plastics
Or the overall structural strength of frame can be improved for being supported to frame in rubber, support glue frame.
By the way that flanging 313 is arranged on side wall 312, make that replace traditional on the inside of side wall 312 for frame
The 31 support glue framves 34 being supported, spatially save installation space occupied by traditional support glue frame 34, make mobile whole
The side frame of end electronic equipment can be made thinner, be conducive to the narrow frame design of mobile terminal electronic equipment.Side wall 312 simultaneously
The upper design with flanging 313 is so that the overall structural strength of frame 31 is more preferable.In addition, being arranged control chip 22 in flanging
Between 313 and the fold area 213 of flexible base board 21, flanging 313 is provided for control chip 22 and is further protected.
The material of frame 31 is generally metal, can be any one in iron frame, steel framework, stainless steel framework, copper frame, alloy frame
Kind.
The interconnecting piece in fold area 213 is connected on the bottom wall 311 of frame 31, and link position is located at the outside of frame 31.Even
The mode connect can be bonding.For example, being bonded by glue or double-sided adhesive etc..
Display screen further includes the polaroid 1, display layer 12, polaroid 2 13 stacked gradually, display layer 12 include upper piece
Glass 121 and lower sheet glass 122, in Fig. 2, COF flexible circuit board 20 is connect with lower sheet glass 122.More specifically, non-curved
It is respectively equipped with connecting pin pin in folding area 211 and fold area 213, flexible base board 21 passes through connecting pin pin in non-flex area 211
It is electrically connected with display screen；Flexible base board 21 passes through the electricity of connecting pin pin and mobile terminal electronic equipment in fold area 213
The connection of road plate, realizes and carries out signal transmission with the mainboard of electronic equipment.
In other examples, COF flexible circuit board and upper sheet glass 121 can also be attached.
The flexible circuit board 39 of backlight module connects the multiple light emitting diode.Meanwhile flexible circuit board 39 is also connected with
Circuit board into mobile terminal electronic equipment.
It further include shade 40 between backlight module and display screen.Shade 40 is for shutting out the light, to prevent backlight
The light that element 32 issues is projected from the side of display screen.It should be understood that shade 40 is not emitted to back light member 32
The light generation of display screen is blocked.Shade 40 can be arranged directly on frame 31, and shade 40 is by frame 31 and backlight mould
Electronic device inside group is bonded together.The flanging 313 is connect with shade 40.In some embodiments, shade 40
For shading glue, the flanging 313 and shading glue sticking.
