Abstract

The utility model relates to a liquid crystal display device and light-emitting device thereof. The liquid crystal display device of the utility model comprises a housing, an array type light-emitting diode and a light guiding group; a plurality of accommodation holes are arranged on the housing, and the array type light-emitting diode is arranged in the housing to serve as light source; the light guiding group provided with a plurality of light guiding posts is arranged above the array type light-emitting diode, wherein, the light guiding posts are corresponding to the accommodation holes respectively, and each light guiding post is combined with the housing through corresponding accommodation holes respectively.

Description

Liquid crystal indicator and light-emitting device thereof

Technical field

The utility model is relevant for a kind of liquid crystal indicator, particularly relevant for a kind of with the array LED device so that the more liquid crystal indicator of multiple message and information to be provided outside the display device display surface.

Background technology

Light emitting diode is applied to the light source of many aspects as display device now, main cause is that operating voltage is low, power consumptive province, rich color, price are low, for example elevator floor digital indicator, air-conditioner temperature digital indicator or traffic sign traffic lights even large-scale electronic board etc.The mode used of light emitting diode initial stage is for being the mode of a luminescence unit with single light emitting diode, the unit that shows as the pattern literal, and the single leaded light post of arranging in pairs or groups is used for light source is effectively guided, to present required effect.Develop by means of single leaded light post being done the matrix form arrangement afterwards, and further and array LED.Yet because one one on single leaded light post is arranged in array when not only taking a lot of work, cost is also higher, and is unfavorable for the downsizing of volume, so how to overcome an above-mentioned difficult problem, has become one of industry important topic.

The utility model content

In view of the shortcoming of prior art, the utility model proposes a kind of liquid crystal indicator, comprising: a housing, an array formula light emitting diode and a leaded light group, housing has a plurality of accommodation holes; Array LED is arranged in the housing, to originate as light; The leaded light group is arranged at array LED top, and has a plurality of leaded light posts, and wherein the leaded light post is corresponding with accommodation hole respectively, and each leaded light post passes corresponding accommodation hole respectively and combines with housing.

In the foregoing liquid crystal indicator, in a preferred embodiment, wherein the leaded light group also comprises a plurality of flanks, connects the leaded light post.

In the foregoing liquid crystal indicator, in a preferred embodiment, wherein the thickness range of flank is 1.5mm to 2.0mm.

In the foregoing liquid crystal indicator, in a preferred embodiment, wherein the length range of flank is 3.5mm to 4.5mm

In the foregoing liquid crystal indicator, in a preferred embodiment, wherein liquid crystal indicator is a LCD TV.

Embodiment

At first see also Fig. 1,2, Fig. 1 is the synoptic diagram of expression the utility model middle shell, and the utility model liquid crystal indicator 10 comprises a housing 1 and a light-emitting device 7, and its middle shell 1 is provided with a display 6, and has a plurality of accommodation holes 2; Display 6 can be flat display apparatus, for example: LCD (Liquid Crystal Display, LCD), plasma scope (Plasma DisplayPanel, PDP), organic light emitting display (Organic Light Emitting Display, OLED) etc., in this example be liquid crystal indicator; And accommodation hole 2 be mode punching out with arrayed on housing 1 for light penetration, and, be used to show messages such as extra image, literal or numeral by means of accommodation hole 2 being set to provide liquid crystal indicator 10 1 additional viewing areas.

Then see also Fig. 2, Fig. 2 is the synoptic diagram of light-emitting device in expression the utility model, light-emitting device 7 comprises: an an array formula light emitting diode 5 and a leaded light group 3, wherein leaded light group 3 is arranged at array LED 5 tops, and has a plurality of leaded light posts 31.

As shown in Figure 3, Fig. 3 is the synoptic diagram that combines with housing of leaded light post in expression the utility model, and leaded light post 31 is corresponding with accommodation hole 2 respectively, and each leaded light post 31 passes the accommodation hole 2 of correspondence respectively and combines with housing 1.In addition, as shown in Figure 4, Fig. 4 is the front schematic view of leaded light group in expression the utility model, and leaded light group 3 also comprises a plurality of flanks 32, is used for connecting leaded light post 31, with as leaded light post 31 bridge that transmits of light each other.In present embodiment, leaded light post 31 is made with integrated shoot mode by plastic material with flank 32, because plastic cement material can have high light transmittance and the ejection formation cost is very cheap, so must compare with the illumination mode that indivedual single leaded light posts are arranged in matrix with existing light emitting diode, can fully reach the effect of saving cost and saving of labor.

In addition, on the whole flank 32 itself is cylindric, its function not merely is as leaded light post 31 interval each other on the structure, when the irradiate light of being sent by array LED 5 during to leaded light group 3, flank 32 also can be brought into play the function of guiding light, and the light guiding is concentrated in the leaded light post 3.In addition, for giving full play to effects that its guiding light of flank 32 are concentrated, the thickness of flank 32 and length range are respectively with between the 1.5mm to 2.0mm and preferable between the 3.5mm to 4.5mm.

In sum, by means of the light-emitting device design of the utility model with array LED, can make LCD except function with show image own, can further demonstrate the information of more images, numeral or literal by means of this light-emitting device, for example show information such as time, channel, but displayable information is not exceeded with aforesaid.

Though the utility model with preferred embodiment openly as above; but it is not in order to limit scope of the present utility model; those skilled in the art do a little change should not break away from scope of the present utility model with retouching, protection domain of the present utility model should be with claim determined and equipollent be as the criterion.
