Refer to Fig. 1, in embodiments of the invention, double-sided liquid crystal display device comprises: parallel the first display panels 10 and the second display panels 20 be oppositely arranged, and is arranged at the backlight module between described first display panels 10 and the second display panels 20.Backlight module comprises: the first optical diaphragm group 31, second optical diaphragm group 32, light guide plate 33, light source 34 and transparent toughened glass 35.Described light source 34 is located on the side of described light guide plate 33, and the side being provided with light source 34 is called incident side, and side is not provided with the face of light source non-light incidence side.Described light guide plate 33 at least comprises an incident side.Namely the present invention adopts lateral incident type backlight module.Described light guide plate 33 also comprises the first exiting surface (unnumbered) and described second exiting surface (unnumbered), the side of light guide plate 33 connects described first exiting surface and described second exiting surface, described first exiting surface is that described first display panels 10 is for light, described second exiting surface is that described second display panels 20 supplies light, and described first exiting surface and described second exiting surface are all provided with site 36.The effect of site 36 be light source 34 outgoing of the side by being positioned at light guide plate 33 light can full illumination on the site 36 on two exiting surfaces of light guide plate 33, and site 36 place on two exiting surfaces scatters in the first optical diaphragm group 31 and the second optical diaphragm group 32, thus providing light source for the first display panels 10 and the second display panels 20, site 36 improves the light-conductive rate of light guide plate.Described light guide plate 33 and the stacked setting of described transparent toughened glass 35.Described light guide plate 33 and described transparent toughened glass 35 are arranged between described first optical diaphragm group 31 and described second optical diaphragm group 32, and described first display panels 10 and the second display panels 20 are separately positioned on the outermost of described first optical diaphragm group 31 and described second optical diaphragm group 32 accordingly.In other words, described light guide plate 33 and described transparent toughened glass 35 is stacked is arranged between described first display panels 10 and the second display panels 20.
Apparent, two exiting surfaces of described light guide plate 33 all arrange site 36 and can increase light-conductive rate, make the bright and dark light degree of described first exiting surface and described second exiting surface about the same, the first display panels is also roughly the same with the display effect of the second display panels.When less demanding for the contrast of the light intensity on two exiting surfaces, also only site 36 can be set on an exiting surface of light guide plate 33.Like this, the intensity near the side light of described site 36 is higher, and the effect of corresponding display is also just relatively good.The light intensity not arranging another exiting surface of site 36 is just relatively weak.
By in double-sided liquid crystal display device in the present invention, in the side of light guide plate, transparent toughened glass is set, to meet the requirement of strength of double-sided liquid crystal display device, and light guide plate can through described tempered glass for the first display panels and the second display panels provide light source, thus reduce backlight module quantity, and can the parts such as metal backing be saved, reach and reduce double-sided liquid crystal display device volume, and reduce the technique effect of production cost.
Further, described backlight module also comprises diffusion barrier 37, and described diffusion barrier 37 is between described light guide plate 33 and described transparent toughened glass 35.The effect of diffusion barrier 37 be to revise light uniformly area source to reach the effect of optics diffusion.Meanwhile, in the present invention, diffusion barrier 37 can also avoid light guide plate and transparent toughened glass directly to contact fraying site 36 in light guide plate 33.In addition, the existence of diffusion barrier 37 can also anti-adsorption particle thing, affects double-sided liquid crystal display device image quality to prevent particle.
Further, on the side not arranging light source 34 of described light guide plate 33, (i.e. non-light incidence side) scribbles reflectance coating (scheming not shown), the light reflection be mapped on it can return in light guide plate 33 by reflectance coating, increase the effect to reflected incident light, while improving optical grade, improve the utilization factor of light.
Optionally, the material of reflectance coating is dirty oil or white oil.White oil, another name paraffin oil, white oil, mineral oil.Chemical constitution: this product is by the potpourri of oil gained refining liquid hydrocarbon, is mainly saturated naphthenic hydrocarbon and alkane mixture, crude oil through normal pressure and vacuum fractionation, solvent extraction and dewaxing, hydrofining and obtaining.Dirty oil, makes a general reference black, the oily heavy thick oils of color in general industry.Generally comprise the residual oil that produces in mink cell focus, bituminous matter oil and refining process, also can refer to the mink cell focus of the high burning-point of making steel in tempering, quenching and water-proofing agent, and have because the scope be applicable to is different summer grade dirty oil and winter black oil not.
Further, on described light guide plate 33 two exiting surfaces, the density arrangement of site 36 is everywhere different.In light guide plate technology, described site is used for light scattering to go out light guide plate 33.Therefore, the density arrangement of described site is more intensive, and the light of described site scattering is more intensive, and then the light intensity of scattering is higher.Because the light intensity in light guide plate 33 and the distance to light source 34 are inversely proportional to, far away with the distance of light source 34, light intensity is less, and therefore light is darker.Vice versa.In order to regulate the light of light guide plate exiting surface place's outgoing to keep evenly, by improving the density in distance light source 34 site 36 at a distance, to increase scattering process, light luminance can be improved.Thus make the emergent light of exiting surface roughly keep even, improve display effect.Namely the dot density stated in light guide plate increases progressively to away from described incident side direction.In other words, higher from light source 34 site 36 density more at a distance, the density from light source 34 site 36 is more nearby lower.
Or, varying in size of site 36 on described light guide plate 33 exiting surface can be set in other embodiments.In light guide plate, within the specific limits, if site 36 is comparatively large, the light that described site 36 is reflected is more, and then the light intensity of certain area internal reflection is higher for the size of described site 36.Because the light intensity in light guide plate 33 and the distance to light source 34 are inversely proportional to, far away with the distance of light source 34, light intensity is less, and therefore light is darker.Vice versa.In order to regulate the light of light guide plate exiting surface place's outgoing to keep evenly, can be comparatively large by improving in distance light source 34 site 36 at a distance, to increase scattering process, improve light luminance.Thus make the emergent light of exiting surface roughly keep even, improve display effect.Namely the site size in described light guide plate increases progressively to away from described incident side direction.In other words, larger from light source 34 site 36 more at a distance, less from light source 34 site 36 more nearby.
