Abstract
The utility model is related to a kind of ultrashort laser away from backlight formula mobile phone backlight module, which includes the FPC double faced adhesive tapes of both diffusion sheet, strip FPC and bonding, wherein：The front of strip FPC is uniformly placed with a row totally ten two LED along its length, and the spacing of two pins of same LED is 2.3mm, and the spacing between adjacent LED pins is that the distance between 1mm, adjacent LED is 5.4mm；Region attachment FPC double faced adhesive tapes between the front bottom margin and LED of strip FPC, and the "T"-shaped extension that part of the FPC double faced adhesive tapes between LED is also extended to form to the top edge of strip FPC；The black one side glue of covering LED region is attached at the bottom margin of diffusion sheet.In the utility model backlight assembly, the arrangement of LED is uniform, and quantity is more, interval is extra small and uniform in light emission, moreover, being designed by the "T"-shaped extension of FPC double faced adhesive tapes, the light direction for making LED is more preferable, so that the brightness everywhere of backlight assembly is more uniformly distributed, display effect is more preferable.
Description
Technical field：
The utility model is related to mobile phone backlight module technical fields, refer in particular to a kind of ultrashort laser away from backlight formula cell phone back optical mode
Group.
Background technology：
In existing mobile phone backlight component, backlight generally using three, four LED as backlight, between them between
It away from larger, be easy to cause local excessively bright and local excessively dark, causes entire screen intensity uneven, influence display effect.
Utility model content：
The purpose of the utility model is to overcome the shortcomings of existing equipment, provide a kind of ultrashort laser away from backlight formula mobile phone
Backlight module.
The technical solution adopted in the utility model is：A kind of ultrashort laser is away from backlight formula mobile phone backlight module, the backlight mould
Group includes the FPC double faced adhesive tapes of both diffusion sheet, strip FPC and bonding, wherein：It uniformly arranges along its length in the front of strip FPC
A row totally ten two LED are furnished with, wherein, odd number sequence number LED series connection, even numbers sequence number LED is also series connection, is between single double group LED
Parallel way；Strip FPC also has the lower extension extended downward；The spacing of two pins of same LED be 2.3mm, phase
Spacing between adjacent LED pins is that the distance between 1mm, adjacent LED is 5.4mm；Strip FPC front bottom margin with
And the region attachment FPC double faced adhesive tapes between LED, and part of the FPC double faced adhesive tapes between LED is also to the top edge of strip FPC
The "T"-shaped extension extended to form forms LED light extractions region between adjacent "T"-shaped extension；The bottom sides of the diffusion sheet
Edge covers the upper surface for being connected to FPC double faced adhesive tapes, and the black single side of covering LED region is attached at the bottom margin of diffusion sheet
Glue.
In the utility model backlight assembly, the arrangement of LED is uniform, and quantity is more, interval is extra small and uniform in light emission, moreover, logical
The "T"-shaped extension design of FPC double faced adhesive tapes is crossed, the light direction for making LED is more preferable so that the brightness everywhere of backlight assembly
It is more uniformly distributed, display effect is more preferable.Meanwhile LED front surface regions have on diffusion sheet black one side glue covering, can prevent light from
It overflows in front.
Description of the drawings：
Fig. 1 is the floor map of FPC in the utility model；
Fig. 2 is the floor map of FPC double faced adhesive tapes in the utility model；
Fig. 3 is the floor map of diffusion sheet in the utility model；
Fig. 4 is the floor map after the utility model combination.
Specific embodiment：
The utility model is further illustrated with reference to specific embodiments and the drawings.
As Figure 1-Figure 4, described in the utility model is a kind of ultrashort laser away from backlight formula mobile phone backlight module, the back of the body
Optical mode group includes the FPC double faced adhesive tapes 3 of both diffusion sheet 1, strip FPC 2 and bonding, wherein：Strip FPC's 2 is positive along length
Direction is uniformly placed with a row totally ten two LED 21, wherein, odd number sequence number LED series connection, even numbers sequence number LED is also series connection, single
It is in parallel way between double groups of LED；Strip FPC 2 also has the lower extension 22 extended downward, to set electric connector；Together
The spacing of two pins of one LED is 2.3mm, and the spacing between adjacent LED pins 23 is 1mm, between adjacent LED
Distance is 5.4mm；Region attachment FPC double faced adhesive tapes 3 between the front bottom margin and LED of strip FPC 2, and FPC is double
The "T"-shaped extension 31 that part of the face glue 3 between LED is also extended to form to the top edge of strip FPC 2, adjacent " T "
LED light extractions region 32 is formed between shape extension 31；The bottom margin covering of the diffusion sheet 1 is connected to the upper of FPC double faced adhesive tapes 3
Surface, and the black one side glue 11 of covering LED region is attached at the bottom margin of diffusion sheet 1.
In the utility model backlight assembly, in terms of front, black one side glue 11, diffusion sheet 1, FPC are followed successively by from top to down
Double faced adhesive tape 3, strip FPC 2.The equal silk-screen white oil of front reverse side of FPC, except the region for having LED pins.
In the utility model backlight assembly, the arrangement of LED is uniform, and quantity is more, interval is extra small and uniform in light emission, moreover, logical
The "T"-shaped extension design of FPC double faced adhesive tapes is crossed, the light direction for making LED is more preferable so that the brightness everywhere of backlight assembly
It is more uniformly distributed, display effect is more preferable.Meanwhile LED front surface regions have on diffusion sheet black one side glue covering, can prevent light from
It overflows in front.
