Brief description

In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment Or in description of the prior art the accompanying drawing of required use be briefly described it should be apparent that, drawings in the following description are only It is some embodiments of the present utility model, for those of ordinary skill in the art, in the premise not paying creative work Under, other accompanying drawings can also be obtained according to these accompanying drawings.

The structural representation of the backlight module that Fig. 1 provides for this utility model embodiment.

Specific embodiment

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of making creative work The all other embodiment being obtained, broadly falls into the scope of this utility model protection.

Referring to Fig. 1, this utility model embodiment provides a kind of backlight module, including backboard 1, backboard 1 is provided with to Few first lamp bar 2 and some the second lamp bars 3, for the first lamp bar 2 and the second lamp bar 3, both can be identical, also may be used Think the different lamp bar of length, each second lamp bar 3 is all installed on backboard 1 along the length direction of backboard 1, and each second lamp bar 3 All be sequentially arranged at intervals along perpendicular to its length direction, each first lamp bar 2 along the length direction perpendicular to the second lamp bar 3 install in Wherein one end of each second lamp bar 3 or two ends.In the present embodiment, the first lamp bar 2 is similar with the structure of the second lamp bar 3, all exists Some lamp bead 4 are installed on pcb board, lamp bead 4 is all spaced successively along the length direction of the first lamp bar 2 or the second lamp bar 3 and sets Put, and be typically chosen LED lamp bead 4.Usually, backboard 1 is rectangle structure, and the second lamp bar 3 all sets along the length direction of backboard 1 Put, and when the length of the second lamp bar 3 is much smaller than the length of backboard 1, then the end position in each second lamp bar 3 installs the first lamp Bar 2, the first lamp bar 2 is along the width setting of backboard 1, and between each first lamp bar 2, then the length direction along backboard 1 is arranged, It can be made to meet the display of the backboard 1 under this size by the first lamp bar 2 and the second lamp bar 3 cooperation this to require.Above-mentioned In arrangement, the display meeting large-size backboard 1 can be coordinated to require, such that it is able to keep away by the lamp bar of reduced size Exempt from that the slow-witted material of a large amount of reduced size lamp bars occurs during batch production backlight module, eliminate small size lamp bar and stay material, reduction Production cost.

Optimize above-described embodiment, lamp bead 4 number in the first lamp bar 2 is identical with the number of the second lamp bar 3, and the first lamp bar Each lamp bead 4 on 2 is located on the extended line of each second lamp bar 3 respectively.In the present embodiment, in the extended line of every one second lamp bar 3 On be respectively provided with the lamp bead 4 in the first lamp bar 2, to play the effect extending the second lamp bar 3 length, so that the second shorter lamp Bar 3 goes on longer backboard 1, and does not affect the display effect of backlight module.Specifically, the first lamp bar 2 and second Lamp bead 4 number in lamp bar 3 is identical, is four, and the first lamp bar 2 is two, and the second lamp bar 3 is four, each second lamp bar 3 Along its width successively uniform intervals arrangement, two the first lamp bars 2 are respectively arranged at the two of each second lamp bar 3 length direction Individual end, is respectively provided with six lamp bead 4 to this on the length direction of every one second lamp bar 3, that is, adopt the lamp of six four lamp bead 4 Bar can reach needs the display that the lamp bar of six lamp bead 4 could meet to require, and this is worked as needs to make the backlight of this size During module, the lamp bar that using the lamp bar with four lamp bead 4, can be prevented effectively from four lamp bead 4 becomes slow-witted material.

The structure of refinement backboard 1, it includes base plate 11 and the side plate 12 along the setting of base plate 11 edge, and this side plate 12 encloses Form circulus, each first lamp bar 2 is mounted on base plate 11 with each second lamp bar 3, and is located in side plate 12.Typically, One lamp bar 2 and the second lamp bar 3 are all fixed on backboard 1 by screw 5, and specifically both of which is fixed on base plate 11 by screw 5 On, certainly every one first lamp bar 2 or the second lamp bar 3 are all fixed on base plate 11 by least two screws 5 along its length On, two connecting portion intervals, to ensure the stability of attachment structure between lamp bar and base plate 11, this is being adopted in this way When making backlight module, compare traditional structure forms and be provided with more screw 5 connecting hole.Optimize above-described embodiment, the first lamp Heat conduction glue-line is all posted between bar 2 and backboard 1 and between the second lamp bar 3 and backboard 1.Heat conduction glue-line has fixing and heat conduction Effect, so that the heat Quick diffusing that each lamp bead 4 produces, simultaneously in the first lamp bar 2 towards the side of base plate 11 and the Two lamp bars 3 also should do insulation processing towards the side of base plate 11, reduce during backlight module uses and produce short circuit phenomenon.

This utility model embodiment also provides a kind of display screen, and including housing and display floater, display floater is embedded peace It is loaded on housing, display screen also includes above-mentioned backlight module, backlight module is arranged in housing and is located at the interior of display floater Side.In the present embodiment, above-mentioned backlight module is applied in display screen, display floater is used cooperatively with backlight module, permissible Form preferable display effect, and because the backlight module of this structure not only can cut down slow-witted material in warehouse additionally it is possible to keep away Exempt from the generation of slow-witted material, greatly reduce the cost of display screen batch making.

The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all this Any modification, equivalent or improvement made within the spirit of utility model and principle etc., should be included in this utility model Protection domain within.
