Specific embodiment

The utility model is described in detail below with reference to embodiment, embodiment is only the preferred reality of the utility model Mode is applied, is not the restriction to the utility model.

Referring to Fig. 1, being a kind of display module provided by the utility model comprising the backlight set gradually from bottom to top Mould group 1, lower substrate 2, upper brandreth 3 and FPC4；The upper brandreth 3 includes panel 31 and the side extended downwardly by 31 edge of panel 32, the side 32 is set to the outside of the lower substrate 2 and the backlight module 1, and the FPC4 includes sequentially connected first Interconnecting piece 41, bending part 42 and second connecting portion 43, the first connecting portion 41 are overlapped on the lower substrate 2, the backlight Gap is formed between the side wall of mould group 1 and the side 32, the side wall that the side wall of backlight module 1 can be center is also possible to The side wall of lower frame, the gap are greater than or equal to 0.8mm, and the bending part 42 is set between the gap in arc-shaped, described Second connecting portion 43 is overlapped in the bottom of the backlight module 1.Due to being formed with foot between the side wall and side 32 of backlight module 1 Enough gaps allow bending part 42 within the cleft, to avoid FPC4 bending amplitude excessive in arc-shaped setting, prevent from showing The case where whitening improves the display quality of display module.

Further, the bending starting point of the bending part 42 and the spacing of the lower substrate 2 are 0.8mm, to guarantee to bend Starting point has with a distance from enough from beer position end, can first connecting portion 41 lower surface and lower substrate 2 junction coating glue, The glue can not only play the role of fixed function or play restriction bending starting point.

Further, the spacing of the circular arc apex of the side wall of the backlight module 1 and the bending part 42 is 0.6mm- 0.8mm avoids FPC4 bending amplitude excessive, prevents display from whitening so that FPC4 can have enough spaces to be bent into arc-shaped The case where occur.

Further, the end of the side 32 is equipped with the recessed portion 33 being recessed inwardly, due to end when upper brandreth 3 stretches Burr easy to form, end can make after being recessed inwardly outwardly without the FPC4 that damages at burr, and control recessed portion 33 Cup depth can make side 32 and the side wall of backlight module 1 be formed with enough gaps so that FPC4 can have it is enough Space is bent into arc-shaped, and recessed portion 33 is preferably concordant with the bottom of backlight module 1.

Referring to Fig. 2, further, the outer surface of the two sides of the first connecting portion 41 sets that there are two mutually stagger setting Stiffening plate 5.In traditional FPC4 design, usually it is not provided with stiffening plate 5 or stiffening plate 5 is set to same position and stiffening plate 5 It is of same size, when causing to extract FPC4, pressure applied is concentrated on same straight line, causes FPC4 route micro- disconnected.This The FPC4 that utility model provides works as extraction since two stiffening plates 5 are located at the two sides of interconnecting piece and mutually stagger setting When FPC4, two sides stiffening plate 5 to FPC4 pressure not on same line segment, stress will not concentrate on same when bending On straight line, thus stress is avoided to concentrate, the route at golden finger is easy micro- disconnected problem, improves product yield.

Further, two signified in the utility model stiffening plates 5 for mutually staggering setting, which can be, is respectively arranged on two A different location；It is also possible to that center position is identical, but two stiffening plates 5 is of different size, as long as making two stiffening plates 5 Stress when bending does not concentrate on same straight line, can avoid stress and concentrates, and the route at golden finger is easy micro- disconnected The problem of, improve product yield.In the present embodiment, stiffening plate 5 includes the first stiffening plate and the second stiffening plate, each stiffening plate 5 Width it is different, central point is in same horizontal line, so that the edge of stiffening plate 5 mutually staggers, without concentrating On same straight line.

Further, the material of the stiffening plate 5 is FR4, PI or stainless steel, in other embodiments, if FPC4 Calorific value is larger, the heat sink material of better heat-radiation effect can also be used, such as aluminium foil stiffening plate 5.

Further, the outer surface of the stiffening plate 5 is equipped with diamond-shaped knurling, so as to can be easier to extract when extracting FPC4, Reduce the risk of FPC4 rupture of line.

Referring to Fig. 3, further, the second connecting portion 43 is equipped with the radium-shine area 6 of two dimensional code, it is located at the two dimensional code The upper surface of second connecting portion 43 in radium-shine area 6 is equipped with dirty oil layer of ink 7 and the white ink layer in the dirty oil layer of ink 7 8, the white ink layer 8 is formed with two dimensional code by radium-shine.Due to being provided with two layers of ink of dirty oil layer of ink 7 and white ink layer 8, lead to Cross laser surface layer white ink layer 8 carry out it is radium-shine fall, expose the dirty oil layer of ink 7 of bottom, the place display that laser is crossed For black, the two dimensional code contrast effect generated in this way is good, is easy barcode scanning, while two dimensional code will not be fallen brokenly Damage, prevents two dimensional code from failing, significantly reduces labour cost.

Further, the dirty oil layer of ink 7 with a thickness of 30 μm~40 μm.The white ink layer 8 with a thickness of 10 μm~ 20μm.The thickness that radium-shine can just be worn with a thickness of common ultraviolet laser, and surrounding has without dust after laser Beat and high-efficient advantage.The reason that 7 thickness of dirty oil layer of ink of lower layer is thicker than 8 thickness of upper layer white ink layer is to avoid laser Power energy fluctuation prevents dirty oil layer of ink 7 from being caused injury by laser perforating to the interior layer of second connecting portion 43.

Above embodiments only express the embodiments of the present invention, and the description thereof is more specific and detailed, but can not Therefore it is interpreted as that a limitation on the scope of the patent of the present invention, as long as the form using equivalent substitution or equivalent transformation is obtained Technical solution, shall fall within the scope of the present invention.
