Embodiment

Characteristics of the present utility model can be consulted the detailed description of the graphic and embodiment of this case and obtained to be well understood to.

As shown in Figure 2, liquid crystal indicator of the present utility model has a liquid crystal panel assembly 10 and to use the light emitting module 20 of light emitting diode 23 at a framework 30 interior constructions, and this light emitting module 20 is made of a support plate 22 and at least one light emitting diode 23 basically; Please cooperate simultaneously with reference to shown in Figure 3, this support plate 22 is a base material by a pliability bottom 221, and be a soft carrying board structure, and on pliability bottom 221, being provided with heat conductive insulating layer 223 and conductive layer 222 in regular turn, each light emitting diode 23 promptly is built on the conductive layer 222 of support plate 22.

When implementing, pliability bottom 221 can be by aluminium, copper, iron, the made soft structure of stainless steel and other metal materials, and the thickness of this pliability bottom is less than or equal to 0.2mm; As for, conductive layer 222 can be comprehensively or the part be bedded on the heat conductive insulating layer 223, it has the circuit 2221 based on copper, and between circuit 2221, be provided with the insulation division 2222 that constitutes by insulating material and supply light emitting diode 23 fixations, 231 cooperations of the lead of light emitting diode 23 continue to circuit 2221 places of conductive layer 22, and form with circuit 2221 and to electrically connect, allow to see through conductive layer 222 and power turn-on.

Moreover heat conductive insulating layer 223 is thought heat-conducting glue or heat conduction film, and this heat-conducting glue can be double faced adhesive tape, constitutes conductive layer 222 by heat conductive insulating layer 223 and combines with pliability bottom 221; Especially, whole light emitting module 20 can be shown in Fig. 4 A, on support plate 22, be provided with cutting line 224 or fold line in advance, to increase the operation ease that light emitting module 20 is cut apart, bent, even can be as shown in Figure 5, further lay a solder layer 225 at support plate 22 below with respect to pliability bottom 221, convenient whole light emitting module directly sticks together on relevant structure.

In the middle of embodiment shown in Figure 2, the framework 30 of liquid crystal indicator includes a base plate 31 and housing 32, and the light source of liquid crystal indicator is relatively from the back side of liquid crystal panel assembly 10; According to this, whole light emitting module 20 can stick together on the base plate 31 of framework 30 with whole support plate 22 as shown in Figure 2, and can be by the effect of support plate 22 cremasteric reflex light emitting diodes 23 light sources; Or directly with support plate 22 by fold line 226, shown in Fig. 4 B, be bent into external form just like base plate.

Or be as shown in Figure 6, support plate 22 is cut into some wall scroll shapes of cutting apart, again a plurality of construction there is the wall scroll shape support plate 22 of light emitting diode 23 to stick together on the base plate 31 of framework 30, when light emitting module 20 meets light emitting diode 23 faults or when damage, only need be changed to get final product at the wall scroll support plates 22 under this light emitting diode 23.

Moreover in the middle of the embodiment shown in Figure 7, the framework 30 of liquid crystal indicator includes a base plate 31, a housing 32 and a side frame 33, and the light source of liquid crystal indicator is relatively from the side of liquid crystal panel assembly 10; Owing to the support plate 22 of whole light emitting module 20 with pliability bottom flexible, the folding characteristic that is that base material has, therefore can be as shown in Figures 7 and 8, the configuration such as bending such as side frame 33 structures such as grade of light emitting module 20 fluid,matching crystal devices, except the design requirement that can meet the Different Light direction, more can obtain preferable light source projects effect by this.

What deserves to be mentioned is, whole light emitting module 20 is when actual operation, the heat conductive insulating layer 223 that can see through support plate 22 discharges light emitting diode 23 thermal source that produces and conduct to pliability bottom 221, and can or wait frame structure release by side frame 33 or base plate, so has preferable heat dissipation.

By being the carrying board structure design of base material with the pliability bottom in the middle of the above-mentioned light emitting module, frame structures such as base plate that can the fluid,matching crystal device, body side frame bending configuration, and the heat conductive insulating layer that sees through support plate discharges thermal source that light emitting diode produces, the light emitting module that one applicability is wide and have preferable heat dissipation is provided really, and the liquid crystal indicator structure with preferable ray cast effect, the application of novel patent is offered in the whence in accordance with the law.
