Embodiment
Below in conjunction with Fig. 1 to Fig. 5, and embodiment is described further the present invention.
Embodiment: referring to Fig. 1 to Fig. 5.
A LCDs, comprises backlight module, and described backlight module comprises light guide plate 4, be enclosed within glue frame 6 outside light guide plate 4, be fixed on the FPC7 of glue frame 6; FPC7 is arranged at the side of light guide plate 4, and FPC7 is provided with a plurality of paster LEDs 8, and between paster LED and light guide plate, is provided with dispersing lens 10.
The present invention adopts paster LED 8 to substitute current LED lamp pearl, is conducive to reduce usage space; Next uses dispersing lens 10, and LED sends light and becomes area source through dispersing lens 10.Dispersing lens 10 can be protruding dispersing lens, also can be for pointolite being become to the symmetrical dispersing lens of rectangular shaped light source.
Further, the incidence surface 102 of described dispersing lens 10 is provided with LED containing hole 101, and incidence surface 102 is the curved surface of epirelief, and the exiting surface of dispersing lens 10 consists of two protruding curved surfaces 23; Dispersing lens 10 is symmetrical structure.
Because LED is pointolite, and rectangular shaped light source is symmetrical light sources, so dispersing lens 10 is symmetrical structure.In design process, should be by the intermediate light powerization of pointolite, thereby adopted exiting surface, be both sides projections, middle recessed structure.
Further, the side of described light guide plate 4 is set to inclined-plane, the side laminating of FPC7 and light guide plate 4, and the back side of described light guide plate 4 is provided with reflectance coating 5.
Due to light guide plate 4 when mounted, its side has one section by glue frame 6, to be covered, in order to increase further space availability ratio, the end face of the light guide plate 4 of this section is set to inclined-plane, thereby formation accommodation space, this accommodation space can be for placing FPC7, thereby saved former in placing the space of FPC7.Because the placement of FPC7 is now for tilting, may cause more light to penetrate from the back side of light guide plate 4, therefore at the back side of light guide plate 4, be provided with reflectance coating 5, most light can be gone out from the front projection of light guide plate 4.
Further, the side of described light guide plate 4 is provided with the shrinkage pool matching with paster LED 8; Paster LED 8 stretches in described shrinkage pool.
LED8 is put into shrinkage pool, be convenient to the setting of FPC7.
Further, the bottom surface of described shrinkage pool is the curved surface 9 of light diffusion.
For the light that LED8 sends can be diffused in light guide plate 4, prevent that light is concentrated, improve the light-emitting uniformity of light guide plate 4.Therefore, the bottom surface of shrinkage pool is designed to the curved surface 9 of light diffusion.
Wherein, described curved surface 9 is concave surface.Similar to the surface of recessed dispersing lens.
Further, the exiting surface of described light guide plate 4 is provided with diffusion sheet 3.
Because the light source of light guide plate 4 is to be provided by the LED8 that is arranged on its side, therefore can more or less cause, light is more in the marginal distribution of light guide plate 4, intermediate distribution is less, in order to improve further, uniformity of light, exiting surface in light guide plate 4 arranges diffusion sheet 3, and light, after diffusion sheet 3, casts out.
Further, the outer prismatic lens 2 that is also provided with of described diffusion sheet 3.
Arrange after prismatic lens 2, the light that light source is sent is assembled to display device user direction, front face brightness can be improved to approximately 100%.
Referring to Fig. 3, the exiting surface of described diffusion sheet 3 is provided with many parallel raised lines, the exiting surface of described prismatic lens 2 is also provided with many parallel raised lines, and the angle between the raised line extending direction on diffusion sheet 3 and the extending direction of the raised line on prismatic lens 2 is 75 to 90 degree.
Further, the outer sealant tape 1 that is also provided with of light guide plate 4.
Flat tape is set, the place beyond the middle part of light guide plate 4 can be blocked, prevent that foreign object from entering, damage light guide plate 4.
Below be only the application's preferred embodiment, equivalent technical solutions on this basis still falls into application protection domain.
