Detailed description of the invention
For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the backlight module that the utility model embodiment provides, comprise light guide plate 2 in backboard 1 of backboard 1 and assembly and lamp bar 3, lamp bar 3 is positioned at the incident side 4 of light guide plate 2, wherein:
The end face that light guide plate 2 is adjacent with incident side 4 has boss 5, and boss 5 extends to the indicator lamp position 6 of display device;
The sidewall of backboard 1 have for boss 5 stretch out by groove 7.
Except backboard 1, light guide plate 2 and lamp bar 3, the primary structure of backlight module also comprises reflector plate, film material group, glue frame etc. usually, and these parts omit not shown in the diagram.Different according to the type of display device, the concrete structure of backlight module also can be different.Such as, as shown in Figure 1, in backlight module, the quantity of lamp bar 3 can be one, and light guide plate 2 is designed to have an incident side 4, and lamp bar 3 is arranged on the incident side 4 of this light guide plate 2.In addition, as shown in Figure 2, in backlight module, the quantity of lamp bar 3 can also be two, and light guide plate 2 is designed to have two incident side 4 that two relative incident side 4, two lamp bars 3 are separately positioned on this light guide plate 2.
The indicator lamp of display device includes but not limited to logo LOGO indicator lamp, standby indicating lamp, start indicator lamp or power supply indicator etc., and its concrete setting position is not limit.As shown in Figure 4, in this embodiment, indicator lamp 11 is positioned at the below of display screen 10.Understandable, the indicator lamp of display device is meeting under clear requirement of lighting, and power consumption is more low better.
Adopt the technical scheme of the utility model above-described embodiment, backing structure and the backlight module of indicator lamp achieve integrated structure design, lamp bar state by controlling backlight module controls the opening and closing of display device indicator lamp, and the part light utilizing backlight module to send serves as the backlight of display device indicator lamp, thus optimize the structure of display device, improve assembling production efficiency, reduce production cost.
In a preferred embodiment of the present utility model, lamp bar 3 is light-emitting diode light bar, comprises many light emitting diodes 8; In many light emitting diodes 8, the light emitting diode near boss 5 is independently controlled luminescence.LED source has low in energy consumption, life-span long, not high, high reliability of cracky, switching speed.Light emitting diode (as the light emitting diode of the bottom in Fig. 1) near boss is designed to independently control luminescence, like this under the connection of display device power supply or holding state, even if display screen is in closed condition, indicator lamp still can normally work.
