Abstract
The utility model relates to the technical field of computer peripherals, in particular to a liquid crystal display. The liquid crystal display comprises a backlight module which comprises a light guide plate, a rubber frame sleeving outside the light guide plate and an FPC (flexible printed circuit) fixed on the rubber frame, and the FPC is arranged on the side face of the light guide plate and provided with multiple surface-mounted LEDs. The LEDs arranged on the FPC of the backlight module are mounted on a main FPC, so that an original FPC of the backlight module can be omitted, and materials are saved; due to the adoption of the surface-mounted LEDs, size of the backlight module is reduced beneficially, and miniaturization of the liquid crystal display is benefited.
Description
Technical field
The utility model relates to computing machine periphery peripherals technical field, specifically, relates to a kind of LCDs.
Background technology
Along with scientific and technological development, LCDs is more and more thinner, more and more less; Especially the LCDs of mobile phone; In order to reach, make the LCDs of mobile phone become thinner, 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 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 a plurality of paster LEDs.
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.
Further, the exiting surface of described light guide plate is provided with diffusion barrier.
Further, described diffusion barrier is also provided with bright enhancement film outward.
The beneficial effect that the utility model is obtained is: the utility model is upper by the LED that is arranged on the FPC of backlight module being contained in to main FPC, can save the original FPC of backlight module, plays saving material; Also adopt paster LED, be conducive to reduce the size of backlight module, be conducive to the miniaturization of display screen simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the fit structure schematic diagram of light guide plate of the present utility model and FPC.
Reference numeral is:
1---sealant tape 2---bright enhancement film 3---diffusion barrier
4---light guide plate 5---reflectance coating 6---glue frames
7---FPC 8---paster LED 9---curved surfaces.
Embodiment
Below in conjunction with Fig. 1 to Fig. 2, and embodiment is described further the utility model.
Embodiment: referring to Fig. 1, Fig. 2.
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.
In traditional LCD MODULE, the light source led 8 of backlight module is (by producer backlight, to be provided) on backlight module, for place LED8 and with the use of power supply, backlight module has the component of a FPC7 carry LED8 and be communicated with the main FPC7 of display screen.Now design is that LED8 backlight is placed on to main FPC7 is upper, backlightly like this saves a FPC7, thereby reduces costs and can improve the timeliness of operation.Thereby help module producer and terminal business (mobile phone, digital etc.) are cost-saving.
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 concavees lens.
Further, the exiting surface of described light guide plate 4 is provided with diffusion barrier 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 barrier 3, and light, after diffusion barrier 3, casts out.
Further, the outer bright enhancement film 2 that is also provided with of described diffusion barrier 3.
Arrange after bright enhancement film 2, the light that light source is sent is assembled to display device user direction, front face brightness can be improved to approximately 100%.
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.
