Abstract
The utility model discloses a backlight source structure for preventing the corner breakage of an LCD (liquid crystal display) device. The backlight source structure comprises an LCM (liquid crystal module) and a backlight source frame, wherein the LCM comprises the LCD device and an FPC (flexible printed circuit) substrate; the LCD device comprises a reflecting board layer and a light source assembly; a clearance position depressed into an inner rim of a backlight source is arranged at an inner frame corner of an inner rim of the backlight source frame; and the LCM is fixed in the inner rim of the backlight source. The utility model adopts the clearance position for the inner frame corner of the inner rim of the backlight source frame and adopts the rounding-off structural design for the clearance position, thereby increasing the elasticity of the inner frame of the backlight source and the mounting space of the LCM, and effectively solving the defect of easy corner breakage of the LCD device. In addition, the manufacture cost is hardly increased, and the backlight source structure has good application prospect.
Description
Technical field
The utility model belongs to the backlight technical field of liquid crystal display, especially relates to a kind of broken back light source structure in the anti-LCD display part angle of products such as mobile phone, digital camera .MP4, PDA, GPS, vehicle-carrying DVD, portable DVD player, electronic digital photo frame and Notebook that is widely used in.
Background technology
LCD (LCD) is widely used in the display technique field, the demonstration of liquid crystal normally forms the function that the liquid crystal of electric field driven between electro-conductive glass realized demonstration by two electro-conductive glass, but liquid crystal itself can not be luminous, therefore need really realize Presentation Function by external light source, be generally the back light source structure that increases LED or other external light source.Usually; backlight inside casing (putting the seat of LCD) all is to adopt common right-angle structure design, this structure through regular meeting because problems such as tolerance, size cooperations, when the LCM module is assembled; cause LCD display part angle and the angle interference of backlight inside casing, cause broken bad in LCD display part angle.In case the broken situation in LCD display part angle occurs, then whole LCM module is just substantially just scrapped, thereby the company of giving and client bring heavy economic losses.The LED in LED-backlit source has the limit to look (Sideview) and top view arrangements such as (Top view) usually, and Side view LED normally is arranged in LED on the FPC substrate of FPC lead-in wire, the light guide plate of packing into then; Adopt this kind structure, the FPC material is had higher requirement, need larger area FPC plate just can produce suitable FPC substrate, be unfavorable for reducing the cost in entire backlight source.
The utility model content
The purpose of this utility model is to provide a kind of broken back light source structure in LCD display part angle of preventing, all adopt clearance position at the inside casing angle of the rim of backlight and clearance position is adopted the rounding structural design, solve prior art and exist and cause the broken defective in LED angle easily.
For achieving the above object, the utility model adopts following technical scheme:
The broken back light source structure in a kind of anti-LCD display part angle, comprise LCM module and backlight frame, described LCM module comprises LCD display part and FPC substrate, described LCD display part comprises reflection flaggy and light source assembly, the rim of described backlight frame, this rim is the glue frame, is provided with the clearance position of recessed backlight rim at the inside casing angle of this rim, and described LCM module is fixed in the backlight rim.
Preferred scheme is: described LCM module comprises LCD display part and FPC substrate, described LCD display part comprises reflection flaggy, light source assembly, diffuser layer, one deck brightening piece layer, shading patch layer at least, described reflection flaggy, light source assembly, diffuser layer, the lamella that adds lustre to, shading patch layer are arranged successively, are fixed in the described backlight rim.
More preferred scheme is: described clearance position is for recessed along backlight rim 30-60 degree inclination angle, and the recessed degree of depth is 1/5～1/4 of a backlight rim, and is the rounding structure.
More preferred scheme is: described light source assembly comprises light guide plate, led light source, at least one side of described light guide plate side has the groove of fixed L ED light source, this led light source is fixed in the described groove, and described led light source is that LED adheres to the limit TV structure on the FPC substrate.
More preferred scheme is: described led light source is single-chip LED and/or multi-chip LED encapsulation.
Compared with prior art, the utlity model has following advantage and beneficial effect:
The utility model adopts clearance position and clearance position is adopted the rounding structural design the inside casing angle of the rim of backlight frame, the elasticity of backlight inside casing and the installing space of LCM module have been increased, can effectively solve the broken defective in the easy angle of LCD display part, and can increase cost of manufacture hardly, have good application prospects.Simultaneously, led light source employing LED of the present utility model adheres to the limit TV structure on the FPC substrate, has saved the cost of manufacture in entire backlight source.

Fig. 1 is an one-piece construction synoptic diagram of the present utility model;
Fig. 2 is the local structure for amplifying synoptic diagram of Fig. 1 corner A part.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details:
As depicted in figs. 1 and 2, a kind of preferred embodiment, comprise LCM module 1 and rectangular backlight source frame 2, LCM module 1 comprises LCD display part and FPC substrate 3, described LCD display part comprises reflection flaggy, light source assembly, diffuser layer, the two-layer lamella that adds lustre to, shading patch layer up and down, described reflection flaggy, light source assembly, diffuser layer, the lamella that adds lustre to, shading patch layer are arranged successively, are fixed in the rim of backlight frame 2.The rim of backlight frame 2 is the glue frame, is provided with the clearance position 21 of recessed backlight rim at the inside casing angle of this rim, and described LCM module is fixed in the backlight rim; This clearance position 21 is recessed along the about miter angle of backlight rim inclination angle, and the recessed degree of depth is 1/5～1/4 of a backlight rim, and the drift angle 211 of clearance position 21 is the rounding structure.When the LCM module is assembled, avoid LCD angle and backlight inside casing angle to interfere mutually, thereby well solved the broken defective in the easy angle of LCD display part.
The described led light source of present embodiment can be single-chip LED encapsulation, also can be the multi-chip LED encapsulation, or single-chip LED and multi-chip LED hybrid package.Light guide plate can be the good resin and plastics of light transmission such as polypropylene or polymethylmethacrylate, the light of light source assembly emission reflects by the reflection flaggy, guarantee that light can be transmitted to diffuser layer through light guide plate and make light be transmitted to the lamella that adds lustre to up and down more uniformly, lustre adding layer evenly is furnished with by the cross one another prism of specified angle up and down, assurance is evenly vertical from the light that the lamella that adds lustre to injects to shading patch layer, thereby guarantees that the light above the shading patch layer evenly distributes.
Above content be in conjunction with structure of the present utility model and the course of work to further describing that it is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
