Technical field
The utility model relates to the liquid crystal technology field, more particularly, relates to a kind of LCDs with better radiating effect.
Background technology
Super brightness LCDs as Message Display Terminal's equipment, selecting for use LED lamp side direction LCD (screen) backlight to be applied in the hot environment, when particularly adopting LED lamp row culture light source, because hot environment or employing high brightness LCDs must adopt than the high-power LED lamp bar, like this, cause the display screen heating than higher, the LCDs that prior art provides comprises preceding frame, be equiped with liquid crystal panel in the frame before described, light guide plate, LED lamp bar and back cover, described light guide plate is parallel to described liquid crystal panel, and be positioned at the inboard of described liquid crystal panel, described LED lamp bar is positioned at the two ends of described light guide plate, described back cover is positioned at the trailing flank of described light guide plate, the back cover radiating effect of the LCDs of this spline structure is bad, can not satisfy the requirement of the high occasion of heating height or ambient temperature to the LCDs heat radiation.
The utility model content
The technical problems to be solved in the utility model is, at existing radiating effect defect of bad, provides a kind of LCDs of good heat dissipation effect.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of LCDs, comprise: preceding frame, be equiped with liquid crystal panel, light guide plate, LED lamp bar and back cover in the frame before described, described light guide plate is parallel to described liquid crystal panel, and is positioned at the inboard of described liquid crystal panel, described LED lamp bar is positioned at the two ends of described light guide plate, described back cover is positioned at the trailing flank of described light guide plate, and wherein, described back cover is for comprising the double layer of metal heat sink at least, be arrangeding in parallel between described every layer of heat sink has the gap, and described heat sink is parallel with described liquid crystal panel.
Wherein, preferred, described heat sink is provided with cellular louvre.
Wherein, preferred, the radiating surface of described LED lamp bar links to each other with the marginal portion of described back cover.
Wherein, preferred, the remainder of described back cover is exposed to the external world.
Implement the technical solution of the utility model, have following beneficial effect: the back cover of this LCDs comprises the multilayer heat sink, described heat sink be arranged in parallel and has the gap, form heat dissipation wind channel between the adjacent heat sink, heat is distributed from described back cover easily, guaranteed the requirement of LCDs heat radiation.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
The structural representation (cross-sectional view) of the LCDs that Fig. 1 provides for the utility model;
The front view of the heat sink of the LCDs that Fig. 2 provides for the utility model.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
The utility model provides a kind of LCDs, comprise: preceding frame 1, be equiped with liquid crystal panel 2, light guide plate 3, LED lamp bar 4 and back cover 5 in the frame 1 before described, described light guide plate 3 is parallel to described liquid crystal panel 2, and be positioned at the inboard of described liquid crystal panel 2, described LED lamp bar 4 is positioned at the two ends of described light guide plate 3, and described back cover 5 is positioned at the trailing flank of described light guide plate 3.Described metal front frame 1 is a location liquid crystal panel exiting surface, and the metal framework that is connected with back cover 5 of marginal portion.Described liquid crystal panel 2, marginal portion not exiting surface are connected with metal front frame 1, and another side is connected with light guide plate 3.Described light guide plate 3, major function is to convert the directional light of incident to the plane vertical light by light principle at random, produces the source of parallel light that light sources produce by LED lamp bar 4 and converts the exiting surface (liquid crystal panel 2) that the plane vertical light reflexes to LCDs to through light guide plate 3.
Described LED lamp bar 4 is LCD side direction interior main heating element backlight.LED lamp bar 4 exiting surfaces are installed on the outside at light guide plate 3 two ends.LED lamp bar 4 radiating surfaces link to each other with the marginal portion of described back cover 5.
In the present embodiment; described back cover 5 is for comprising double layer of metal heat sink 51 at least; described heat sink 51 can be used as back cover 5 simultaneously; this LCDs is played the effect of protection; in addition; this heat sink 51 be installed on described before in the frame 1, be arrangeding in parallel between described every layer of heat sink 51 has the gap, described heat sink 51 is parallel with described liquid crystal panel 2.Form heat dissipation wind channel in the gap of leaving between every layer of metallic heat radiating plate 51 between appropriate gap and the adjacent two layers metallic heat radiating plate 51, described heat dissipation wind channel communicates mutually, and communicate with the external world, the simplest mode is in heat sink 51 upper sheds, adjacent heat dissipation wind channel is communicated mutually, and communicate with the external world, in the preferred embodiment, cellular louvre 6 is set on described heat sink 51.Like this, local air between the multilayer heat sink 51 or heat are interconnected through cellular louvre 6, and ventilation effect is better, and radiating effect is also better.
In a further embodiment, the radiating surface of described LED lamp bar 4 links to each other with the marginal portion of described back cover 5.Expanded the area of dissipation of main heating element LED lamp bar 4 in the LCD side direction is backlight, the LED lamp bar 4 as heater can better be dispelled the heat.Other parts of described back cover 5 (being a plurality of heat sinks 51) can be installed in the former frame, can be exposed to external world's (promptly being exposed in the air), and in the preferred embodiment, the remainder of described back cover 5 is exposed to the external world.Like this, heat can be gone by these shell 5 easier being dispersed in the air that are exposed to extraneous part.
To sum up, conduction and diffusion mutually between the metallic heat radiating plate of heat in back cover 5 that the main heating element LED lamp bar 4 in the LCD side direction is backlight produces, solved the heat dissipation problem of main heating element LED lamp bar 4 effectively, prevented local overheatings in the main heating element LED lamp bar 4 and cause the damage of LED lamp bar 4 even LCD side direction module backlight.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
