Background technology
Along with scientific and technological development, LCDs is more and more thinner, more and more less; Especially the LCDs of mobile phone; Make the LCDs of mobile phone become thinner in order to reach, people constantly improve on liquid crystal display module, from before direct putting type develop into present side-light type, the light source of liquid crystal display module is set to the side of light guide plate; Owing to focusing on the optical design of liquid crystal display module always, make the development of LCDs enter into a bottleneck, can not further reduce the size of LCDs, the development of LCDs is hindered, therefore need to improve from other structures of LCDs.
Summary of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, and a kind of LCDs is provided, and the size of this LCDs is little, and cost is low.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of LCDs, comprises backlight module, and described backlight module comprises light guide plate, be enclosed within glue frame outside light guide plate, be fixed on the FPC of glue frame; FPC is arranged at the side of light guide plate, and FPC is provided with multiple paster LEDs, and is provided with dispersing lens between paster LED and light guide plate.
Further, also comprise diffusion sheet and prismatic lens, diffusion sheet is arranged at the exiting surface of light guide plate, prismatic lens is arranged at outside diffusion sheet, the exiting surface of described diffusion sheet is provided with many parallel raised lines, the exiting surface of described prismatic lens is also provided with many parallel raised lines, and angle between the extending direction of raised line on raised line extending direction and prismatic lens on diffusion sheet is 75 to 90 degree.
Further, the side of described light guide plate is set to inclined-plane, the side laminating of FPC and light guide plate, and the back side of described light guide plate is provided with reflectance coating.
Further, the side of described light guide plate is provided with the shrinkage pool matching with paster LED; Paster LED stretches in described shrinkage pool.
Further, the bottom surface of described shrinkage pool is the curved surface of light diffusion.
Wherein, described curved surface is concave surface.Similar to the surface of concavees lens.Certainly, in shrinkage pool, also can be provided for the lens of light diffusion.
The beneficial effect that the utility model is obtained is: the utility model adopts paster LED to be conducive to the volume miniaturization of LCDs, between LED and light guide plate, dispersing lens is set simultaneously, and the light source that is conducive to keep to enter light guide plate is area source.

Fig. 3 is the fit structure schematic diagram of diffusion sheet of the present utility model and prismatic lens.
Reference numeral is:
1---sealant tape 2---prismatic lens 3---diffusion sheet
4---light guide plate 5---reflectance coating 6---glue frames
7---FPC 8---paster LED 9---curved surfaces
10---dispersing lens.
Embodiment
Below in conjunction with Fig. 1 to Fig. 3, and embodiment is described further the utility model.
Embodiment: referring to Fig. 1, Fig. 2.
A kind of 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 multiple paster LEDs 8, and between paster LED and light guide plate, is provided with dispersing lens 10.
The utility model adopts paster LED 8 to substitute current LED lamp pearl, is conducive to reduce usage space; Secondly use dispersing lens 10, LED sends light and becomes area source through dispersing lens 10.Dispersing lens 10 can be convex lens, also can be for pointolite being become to the non-sym lens of rectangular shaped light source.
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 to be covered by glue frame 6, 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 for place FPC7, thereby saved former in placing the space of FPC7.Because the placement of FPC7 is now inclination, may cause more light to penetrate from the back side of light guide plate 4, be therefore provided with reflectance coating 5 at the back side of light guide plate 4, 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 concavees 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, uniformity of light in order to improve further, at the exiting surface of light guide plate 4, diffusion sheet 3 is set, 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 angle between the extending direction of raised line on raised line extending direction and prismatic lens 2 on diffusion sheet 3 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.
The utility model has been done to explain, and those of ordinary skill in the art should be appreciated that and can modify or be equal to replacement the technical solution of the utility model, and do not depart from essence and the scope of technical solutions of the utility model.
