As shown in Figure 1, the utility model embodiment provides a kind of novel backlight structure, the back light source structure is generally
It is rectangular, include the backboard 100 and center 200 of mutual snapping, the backboard 100 has bottom plate 110 and upward by 110 periphery of bottom plate
The side plate 120 extended is bent, is equipped with reflector plate 300, light guide plate 400 and the light of sequence setting on the bottom plate 110 from the bottom up
Film group 500 is learned, the light guide plate 400 is at least one side as incidence surface and upper surface as light-emitting surface, corresponding light guide plate
400 incidence surface, the back light source structure are additionally provided with luminescence component 600, and the side plate 120 is in the side equipped with luminescence component 600
Face is bent inwards by the top of side plate 120 extends to form extension 130, the luminescence component 600 and with luminescence component 600 close to
One end of light guide plate 400 be placed in the space that extension 130 and backboard 100 are formed and the end light guide plate 400 and extension
Portion 130, which abuts, to be fixed.When assembly, the luminescence component 600 is fixed in groove, and light guide plate abuts at the end with extension 130
It fixes and is extended the fixation for realizing the light guide plate close to luminescence component one end after the downward pressure in portion 130 is pushed down.
Further, the light guide plate 400 is additionally provided with adhesive 700 in the lower face of one end far from luminescence component 600,
The adhesive 700 makes light guide plate 400 be adhesively fixed with bottom plate 110, and then realizes the light guide plate far from luminescence component one end
It is fixed.Preferably, the adhesive 700 is double-sided adhesive.
Luminescence component 600 described in the utility model includes the LED light on wiring board 610 and setting assist side 610
620, the socket of the LED light 620 corresponds to the incidence surface of light guide plate 400, the wiring board 610（As shown in Figure 1）It can be with leaded light
The lower face of plate 400 is affixed to make luminescence component 600 be fixed together with light guide plate, convenient for assembly；Also can as shown in Fig. 2,
The wiring board 610 is affixed with the inside of side plate 120 and then realizes being fixedly connected for luminescence component 600, at this point, the light guide plate
400 need to add location structure in the side of close luminescence component 600 makes the light-emitting window of light guide plate 400 and LED light 620 keep certain

Film can be such that light is spread from the right and left, and almost dull thread projects upper and lower directions, which is used in the middle control of automobile
On display screen, the light after deflection solves the problems, such as the image inverted image of vehicle-mounted middle control display screen to windshield, while also expanding
The wide visual angle of the right and left, makes driver and copilot that can be clearly apparent the content of middle control display screen, improves light
Utilization rate, and the cost of the cost of manufacture ratio ALCF films of batswing tab diffusion barrier is low, is conducive to volume production and is widely used.
The snap fit of backboard 100 described in the utility model and center 200 can be used any normal in the prior art
The fixed connection structure of rule, such as snap connection or be threadedly coupled, therefore not to repeat here.
Wiring board 610 described in the utility model is electrically connected with external circuit to realize that the energization of LED light 620 sends out linear light
Source, linear light source, which enters in light guide plate 400, is converted into equably area source, and reflector plate 300 can will be incident to 400 bottom of light guide plate
Light be reflected back the brightness that light source is improved in light guide plate 400, light-emitting surface of the area source in light guide plate 400 from light guide plate 400
It can more uniformly be shown by optical film group 500 after injection.Using the back light source structure of the utility model, light guide plate can be made tight
Gu being particularly suitable for middle large scale（Viewing area is 10.1 or more）And vehicle-mounted backlight display.
Finally, it should be noted that above example be only to illustrate the embodiment of the present invention technical solution rather than to its into
Row limitation, although the embodiment of the present invention is described in detail with reference to preferred embodiment, those skilled in the art
It should be understood that the technical solution of the embodiment of the present invention can be still modified or replaced equivalently, and these are changed or wait
The range of modified technical solution disengaging technical solution of the embodiment of the present invention cannot also be made with replacement.
