Description
Technical field
The utility model belongs to the liquid crystal indicator field, relates in particular to the high ultra-thin liquid crystal indicator of a kind of radiating efficiency.
Background technology
Progress along with science and technology, liquid crystal indicator develops towards ultra-thin and large scale direction, but pursuing ultra-thin and large-sized while, cause the liquid crystal indicator inner space narrow and small, can run into the problem of heat radiation difficulty unavoidably, and the panel of liquid crystal indicator and bonnet all be to adopt plastic cement material, though offer a lot of louvres thereon, but the plastic cement material radiating efficiency is poor, equally also can't solve the problem of heat radiation difficulty.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of radiating efficiency high ultra-thin liquid crystal indicator.
The utility model is to realize like this, the ultra-thin liquid crystal indicator that a kind of radiating efficiency is high, comprise panel, bonnet, liquid crystal panel, pcb board and LED, described panel and bonnet are metalwork, described LED is welded on the pcb board, described pcb board closely contacts with described panel, and described panel also closely contacts with described bonnet.
Unlike the prior art, the utility model adopts the panel and the bonnet of metal material, then pcb board is closely contacted with panel, panel also closely contacts with bonnet, because the panel and the bonnet thermal diffusivity of metal material are good, the heat that LED on the pcb board produces is very fast to distribute by panel and bonnet, has improved the radiating efficiency of ultra-thin liquid crystal indicator significantly, has guaranteed the operate as normal and the serviceable life of ultra-thin liquid crystal indicator.

Fig. 2 is the synoptic diagram that the two sides, front and back of the panel that provides of the utility model embodiment one all offers the panel louvre;
Fig. 3 is the synoptic diagram of the high ultra-thin liquid crystal indicator of the another kind of radiating efficiency that provides of the utility model embodiment two.
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.
As shown in Figure 1, the ultra-thin liquid crystal indicator that a kind of radiating efficiency that the utility model provides is high, comprise panel 11, bonnet 12, liquid crystal panel 13, pcb board 15 and LED16, described panel 11 and bonnet 12 are metalwork, described LED16 is welded on the pcb board 15, and described pcb board 15 closely contacts with described panel 11.Unlike the prior art, the utility model adopts the panel 11 and the bonnet 12 of metal material, then pcb board 15 is closely contacted with panel 11, simultaneously, panel 11 is also closely contacted with bonnet 12, because the panel 11 and bonnet 12 thermal diffusivities of metal material are good, the heat that the LED16 on the pcb board 15 produces is very fast to distribute by panel 11 and bonnet 12, improve the radiating efficiency of ultra-thin liquid crystal indicator significantly, guaranteed the operate as normal and the serviceable life of ultra-thin liquid crystal indicator.
Below the utility model is done concrete the introduction.
Embodiment one:
As depicted in figs. 1 and 2, the ultra-thin liquid crystal indicator that a kind of radiating efficiency that present embodiment one provides is high, comprise panel 11, bonnet 12, liquid crystal panel 13, pcb board 15 and LED16, described panel 11 and bonnet 12 are metalwork, described LED16 is welded on the pcb board 15, described pcb board 15 closely contacts with described panel 11, and described panel 11 also closely contacts with described bonnet 12.
Particularly, the back side of described liquid crystal panel 13 and a light guide plate 14 are fitted, and described LED16 is located at the side of described light guide plate 14, forms the liquid crystal indicator of side light inlet.
More specifically, described pcb board 15 offers threaded hole 111 with the contact position of described panel 11, and by screwing in the screw (not shown) realization pcb board 15 of threaded hole 111 and fixedlying connected of panel 11, and connect between back pcb board 15 and the panel 11 for face contacts, so that the heat of the generation of the LED16 on the pcb board 15 in time passes to panel 11.
In addition, described panel 11 both sides are provided with heat radiation chamber 112, offer the some panel louvres 113 that are communicated with described heat radiation chamber 112 on the described panel 11, described panel louvre 113 both can be opened in the back (as shown in Figure 1) of panel 11, also can be opened in the front (as shown in Figure 2) of panel 11 simultaneously, to increase the radiating efficiency in heat radiation chamber 112; Also offer the bonnet louvre 121 that is communicated with described panel louvre 113 on the described bonnet 12.The heat that LED16 on the described pcb board 15 distributes, at first enter heat radiation chamber 112, enter the heat in the heat radiation chamber 112, a part directly distributes by the panel 11 of metal material and the heat conduction of bonnet 12, another part distributes by panel louvre 112 and bonnet louvre 121, thereby has further improved radiating efficiency.
Further, in order to improve the radiating efficiency of described panel 11 and bonnet 12, described panel 11 and bonnet 12 all adopt aluminium, copper, aluminium alloy, aldary or other metal alloys of good heat conductivity to make.
