Further, base plate connects near one end of glue frame the fixed plate for fixing pcb board, and base plate connects near the side of light guide plate substrate, and substrate connects has several for the support column supporting light guide plate.
What this utility model obtained has the beneficial effect that this utility model, by arranging claw, while playing lightguide plate fixing effect, also acts as the effect shut out the light, it is to avoid light directly casts out from the gap of fixed frame, prevents light leak.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Reference is:
1 glue frame 2 fixed plate
3 pcb board 4 LED
5 claw 6 reflective membranes
7 light guide plate 8 base plates
9 support column 10 substrates.
Detailed description of the invention
Below in conjunction with the accompanying drawings and this utility model is described further by detailed description of the invention.
Embodiment: see Fig. 1.
A kind of LCDs of light leakage, including backlight module and fixed frame, described fixed frame includes base plate 8 and the glue frame 1 of fixing connection, base plate 8 and glue frame 1 surround accommodation space, described backlight module is arranged in accommodation space, backlight module includes light guide plate 7, it is positioned at the LED module of light guide plate 7 side and is arranged at the blooming piece of light guide plate 7, LED module is between light guide plate 7 and glue frame 1, the exiting surface of light guide plate 7 is provided with draw-in groove near the side of LED module, described glue frame 1 is extended with the claw 5 matched with draw-in groove to light guide plate 7 direction, claw 5 stretches into draw-in groove.
In the technical program, by arranging draw-in groove on light guide plate 7, glue frame 1 arranges claw 5, thus LED module is sealed between glue frame 1 and backlight module, even if glue frame 1 expanded by heating, claw 5 is not easy to leave from draw-in groove, thus effectively prevent the generation in gap, prevent light leak.
Further, claw 5 includes the contact site stretching into draw-in groove, and the cross section of described contact site is triangular in shape.
Triangle is arranged so that be difficult to loosen after claw 5 and card slot fit.
Further, the lower surface of claw 5 is provided with reflective membrane 6.
In order to improve light utilization efficiency further, reflective membrane 6 is set in the lower surface of claw 5 so that light is preferably utilized.
Further, described LED module includes LED4 and pcb board 3, and described light guide plate 7 is provided with the shrinkage pool (being not drawn in figure) matched with LED4 near the side of LED module.
Shrinkage pool is set for housing LED4 so that the throw light of LED4 is tried one's best most entrance light guide plate 7, reduces the probability of light leak.
Further, described pcb board 3 surface is provided with reflective membrane 6.
Reflective membrane 6 is set and can improve light utilization efficiency further.
Further, the outside of light guide plate 7 is provided with optics module (being not drawn in figure), and described optics module includes being set in turn in the diffusion sheet of light guide plate 7 exiting surface, lower prism film and upper prism film.
Diffusion sheet is used for adjusting angular so that light more homogenization, and light is adjusted to axially by lower prism film and upper prism film, and the projection length direction of upper prism film is vertical setting with the projection length direction of lower prism film.
Further, described claw 5 side is provided with the agnail (being not drawn in figure) for preventing claw 5 from departing from.
Agnail is set, the fixing of light guide plate 7 can be strengthened.
Further, base plate 8 connects near one end of glue frame 1 fixed plate 2 for fixing pcb board 3, and base plate 8 connects near the side of light guide plate 7 substrate 10, and substrate 10 connects has several for the support column 9 supporting light guide plate 7.
After fixed plate 2 is set, in that context it may be convenient to pcb board 3 is fixed；Avoid loosening.Secondly, substrate 10 and support column 9 are set, in that context it may be convenient to supported by light guide plate 7.Support column 9 is used to form heat-dissipating space in making fixed frame, it is simple to heat spreads, scatters and disappears.
Below being only the preferred embodiment of the application, equivalent technical solutions on this basis still falls within application protection domain.
