Abstract

The utility model discloses a straight-down type LED liquid crystal module and belongs to the technical field of LED liquid crystal module structures. The straight-down type LED liquid crystal module comprises a backboard, a reflection plate, a diffusion plate, a diaphragm, a middle frame, liquid crystal glass and a face frame. The backboard, the reflection plate, the diffusion plate, the diaphragm, the middle frame, the liquid crystal glass and face frame are sequentially connected in a stacked manner from inside to outside, and strip protrusions protruding outwardly are evenly distributed on two side edges and the upper lateral edge of the backboard; the length direction of the strip protrusions is identical to the length direction of the edges of the strip protrusions. The straight-down type LED liquid crystal module is low in manufacturing cost and high in production efficiency.

Description

Straight-down negative LED liquid crystal module

Technical field

the utility model belongs to LED liquid crystal display module structure technical field, relates in particular to a kind of straight-down negative LED liquid crystal module.

Background technology

straight-down negative LED liquid crystal module market competition grows in intensity, product requirement diversity, construction cycle and change the focus that mould cost Shi Ge businessman is concerned about.At present, a lot of liquid crystal module are because design preset clearance is less than normal or change optical plan etc. between development stage, and high temperature ageing experiment can cause diaphragm wrinkling and fall vibrations experiment diaphragm friction scratch/diaphragm to jump out center etc. a series of abnormal.Extremely relate to center and backboard rigging position repairs a die, repair a die workload and expense are huge.Scheme, the time that repairs a die, the cost that repairs a die, the risks that repair a die etc. of repairing a die have a strong impact on development of projects and market share.

Summary of the invention

the utility model is exactly for the problems referred to above, and the straight-down negative LED that a kind of cost of manufacture is low, production efficiency is high liquid crystal module is provided.

for achieving the above object, the utility model adopts following technical scheme, the utility model comprises backboard, reflector plate, diffuser plate, diaphragm, center, liquid-crystalline glasses and face frame, backboard, reflector plate, diffuser plate, diaphragm, center, liquid-crystalline glasses, face frame be stack connection successively from the inside to the outside, and its structural feature backboard dual-side and upper horizontal edge are evenly equipped with strip projected parts laterally; The length direction of strip projected parts is consistent with the length direction on limit, place.

as a kind of preferred version, totally six of the strip projected parts of dual-side described in the utility model, three of every sides; The strip projected parts of upper horizontal edge is four.

as another kind of preferred version, backboard described in the utility model adopts five metals SGCC backboard.

in addition, the uniform some triangular prism bulge-structures of a side surface of diffuser plate described in the utility model, the uniform some ball arc depressions in opposite side surface and ball arc projection cross structure.

the utility model beneficial effect.

the utility model backboard dual-side and upper horizontal edge are evenly equipped with strip projected parts laterally; The length direction of strip projected parts is consistent with the length direction on limit, place.By adjusting strip projected parts height, the spacing of capable of regulating diaphragm and center, needn't make mould again, has reduced cost of manufacture, has improved production efficiency.In addition, strip projected parts is set, has the effect of the backboard of reinforcement intensity, also can be convenient to adjust provides different blended electrical distance.

Accompanying drawing explanation

below in conjunction with the drawings and specific embodiments, the utility model is described further.The utility model protection domain is not only confined to the statement of following content.

fig. 1 is the utility model structural representation.

fig. 2 is the utility model rear view.

in figure, 1 be backboard, 2 for strip projected parts, 3 for reflector plate, 4 for diffuser plate, 5 for diaphragm, 6 for center, 7 for liquid-crystalline glasses, 8 for face frame, 9 for ball arc projection, 10 for ball arc depression, 11 for triangular prism protruding.

Embodiment

as shown in the figure, the utility model comprises backboard 1, reflector plate 3, diffuser plate 4, diaphragm 5, center 6, liquid-crystalline glasses 7 and face frame 8, backboard 1, reflector plate 3, diffuser plate 4, diaphragm 5, center 6, liquid-crystalline glasses 7, face frame 8 be stack connection successively from the inside to the outside, and backboard 1 dual-side and upper horizontal edge are evenly equipped with strip projected parts 2 laterally; The length direction of strip projected parts 2 is consistent with the length direction on limit, place.

totally six of the strip projected parts 2 of described dual-side, three of every sides; The strip projected parts 2 of upper horizontal edge is four.By test, strip projected parts 2 is so set, can reach good gap and adjust effect.

described backboard 1 adopts five metals SGCC backboard.

the uniform some triangular prism projections of one side surface 11 structures of described diffuser plate 4, the uniform some ball arc depressions 10 in opposite side surface and ball arc projection 9 cross structures.When diffuser plate 4 receives the light of the light source passing over, light, through diffuser plate 4 one side surface triangular prism projection 11 structure refractions, reflection, arrives opposite side surface; Light through ball arc depression 10 and 9 refractions of ball arc projection, scattering, becomes pointolite into area source again, and transmittance obviously improves.

be understandable that, above about specific descriptions of the present utility model, only for being described, the utility model is not limited to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can modify or be equal to replacement the utility model, to reach identical technique effect; As long as meet, use needs, all within protection domain of the present utility model.
