Abstract
The utility model discloses an LCD (Liquid Crystal Display) backlight module with a housing and an LGP (Light Guide Plate) free of a fastening design. The LCD backlight module with the housing and the LGP free of the fastening design comprises a light source assembly, the housing, the LGP, a lower iron frame and an optical film sheet. A reflective piece is firstly pasted on the back of the housing, then the LGP is inserted into the housing through steps on the tail portion, the front of the LGP is directly placed on the housing, the LGP is pressed through light emitting light bars, an optical film is attached on the upper surface of the LGP, the optical film is formed by an optical diffusion sheet, an upper light enhancement film, a lower light enhancement film and a light-proof curtain tape which covers on the optical diffusion sheet edge. The LCD backlight module with the housing and the LGP free of the fastening design is efficient in production and assembling and suitable for market mainstream ultrathin mobile phones with narrow frames.
Description
Technical field
The utility model relates to LCD module backlight, belongs to the display element technical field.
Background technology
Existing mobile phone LCD backlight module, when the user watches picture from the side of LCD, bright spot appears in the buckle place, or fringence enters the luminous zone, and the main cause that this problem occurs is because adopting traditional side buckle design, because ray refraction and reflection are difficult control, light is gathered in the buckle point can form bright spot, light has the light beam phenomenon in the reflection of concentrated buckle place, the particularly narrow frame design of mobile phone at present, and photomask can not have good covering to influence the product effect by opposite side.
The utility model content
At the problems referred to above, the utility model provides a kind of LCD module backlight, improves to overcome the defective of prior art by three aspects: (1) removes the buckle of LGP light source both sides; (2) buckle of removal glue frame light source both sides; (3) brandreth guarantees that LGP is in level in module backlight under the use, guarantees the validity of luminous efficiency.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of have a LCD module backlight that glue frame and LGP do not have the buckle design, described LCD module backlight comprises that LGP, light source assembly, blooming piece, glue frame reach brandreth down, wherein earlier reflector plate is adhered to the glue frame back side with double faced adhesive tape, again LGP is positioned on the reflector plate, the wiring board that will have double faced adhesive tape is again pushed down the source ends of advancing of LGP, to play brandreth to fasten the glue frame, keep LGP to be placed horizontally between glue frame and the reflector plate, the LGP surface is placed diffusion sheet, following brightening piece successively, goes up brightening piece, is covered with the black and white photomask at last; Light source assembly comprises flexible PCB and a plurality of LED that are connected circuit board surface.
Further, described LGP is directly done flat.
Further, described glue frame light source dual-side is done narrow to 1-1.2mm.
Earlier reflector plate is adhered to the glue frame back side by double faced adhesive tape, LGP directly is placed on the reflector plate, will reflect button Star by following chase and still can well cooperate with the glue frame to LGP, does not influence product optics.Entire module comprises that LGP, light source assembly, blooming piece, glue frame reach brandreth down, wherein at the glue frame back side reflector plate is gummed down earlier, again LGP is utilized the step of afterbody to insert the glue frame, the front directly is positioned on the glue frame, by luminous lamp strip LGP is pushed down, the back side has guaranteed that by following brandreth compacting LGP is placed horizontally between glue frame and the following brandreth, upper surface at LGP is pasted with blooming, and bright enhancement film was formed with the light tight black and white glue that covers the light diffusing sheet edge about blooming was reached by light diffusing sheet.
Pass through said structure, after glue frame and LGP remove the buckle of assembling, the smooth level in two sides, be more conducive to the optical engineer to the control of light, namely be used in the narrow frame smart mobile phone of present main flow, side also can not occur has the visual situations of influence such as bright spot, white group to take place, and has improved product quality, saves a line Manufacturing Worker assembling man-hour.
In the utility model, described LGP removes the buckle of dual-side, and source ends light is radiated at sidewall uniformly and reaches the soft of light in the case.
At the narrow frame of the product of modern LCD, lightening requirement, the applicant has scrutinized the supporting effect of LGP, remove buckle after, can solve the bright spot ray phenomenon of consumer's feedback by multiple authentication.
In the utility model, after the glue frame removes buckle, can reduce operation in the processing of glue frame mould, and eliminate the risk of edge burr, all improve significantly in each station.
By above-mentioned improvement, the LCD that the utility model provides module backlight has been realized client and consumer to the product thin typeization, the ideal effect of narrow frame.
