Abstract
The utility model provides a structure of a rubber frame LED (light-emitting diode) outlet of a backlight. The structure comprises an upper iron frame (10), a lower iron frame (29), upper and lower bright enhancement films (30) arranged between the upper iron frame (10) and the lower iron frame (20), a lower diffusion film (40), a rubber frame (50), a flexible circuit connecting plate (60), a light conductive plate (70) and a reflecting film (80); the structure further comprises an LED light (90) which is fixed on the rubber frame (60), wherein the part on the rubber frame (60) and provided with the LED light (90) is a plane. According to the structure of the rubber frame LED outlet of the backlight, the rubber frame LED outlet of the traditional backlight product is out of an LED bayonet groove; FPC (flexible printed circuit) subassembly is moved from the positive face to the negative face of the rubber frame; the structure can be perfected because the quantity of the LED can be changed without modifying the position of the bayonet of the rubber frame, and the structure can be directly used; the luminance of the finished product can be improved; and the cost on the luminance of the LED can be reduced; the cost of developing material of the product can be greatly reduced; and the assembling efficiency can be improved as well.
Description
Technical field
The utility model relates to display unit, particularly the structural design of backlight.
Background technology
The LED export structure that has the glue frame of traditional backlight product at present now all is that the LED draw-in groove is arranged, and is as shown in Figure 1; Because of the LED screens of its structure is a fixed, and its structure to cover material tool many, along with the variation in epoch, to backlight product require increasingly high; The more past ultra book type Gao Liang of trend, socket look imitates no lamp holder dark space, reaches the development with a its LED number change backlight, and this structure has certain limitation in this respect; Basically settle finally, perfect space is little, and; Used material tool is many, need establish the position that becomes the LED draw-in groove because of LED quantity is different, has then increased the expensive cost that repairs a die.
Summary of the invention
The utility model provides a kind of backlight that does not have screens, adopts the glue frame that the structure of screens is not set, and screens can't be used LED number change and the high technical problem of the cost that repairs a die in the solution prior art.
The utility model is to solve the problems of the technologies described above the glue frame that provides not have LED screens backlight and comprise chase and following chase; Should go up and be provided with upper and lower bright enhancement film (BEF), following diffusion barrier, glue frame, flexible circuit connecting plate (FPC), LGP and reflectance coating between chase and the following chase; Also include the LED lamp; This LED lamp is fixed on the said glue frame; It is the plane that said glue frame is installed said LED lamp place, fixes through the foam glue bond between said glue frame and the last chase, and said flexible circuit connecting plate connects said glue frame through double faced adhesive tape.
The utility model is designed to not be provided with LED bayonet slot position through the LED outlet position with the glue frame of traditional backlight product; The FPC assembly is changed to glue frame reverse side by the front; Its structure can be improved because of the LED number change need not revise its glue frame bayonet socket position, directly can be shared, and finished product brightness is improved; Minimizing will significantly reduce the product development Material Cost and improve packaging efficiency because of the cost of LED brightness.
Description of drawings
Fig. 1 is the sketch map of traditional glue frame.
Fig. 2 is the sketch map of glue frame in the utility model.
The structural representation of Fig. 3 traditional backlight product.
Fig. 4 is the backlight product structural representation of the utility model.
The specific embodiment
Specific embodiment in conjunction with above-mentioned description of drawings the utility model.
By knowing among Fig. 2 and Fig. 4; The structure of this backlight glue frame LED outlet position comprises chase 10 and following chase 20; Should go up and be superimposed with upper and lower bright enhancement film 30 between chase 10 and the following chase 20 successively, descend diffusion barrier 40, glue frame 50, flexible circuit connecting plate 60, LGP 70 and reflectance coating 80; Also include LED lamp 90, this LED lamp 90 is fixed on the said glue frame 60, and it is the plane that said glue frame 60 is installed said LED lamp 90 places; Fixing through foam glue 51 bondings between said glue frame 50 and the last chase 10, said flexible circuit connecting plate 60 connects said glue frame 50 through double faced adhesive tape 52.
Structure in the utility model is that LED screens 53 is not set on the glue frame, and the glue frame of avoiding causing because of the LED number change is inapplicable, and back light source structure of the prior art is as shown in Figure 3; Be respectively chase 10, flexible circuit connecting plate 60, upper and lower bright enhancement film 30, following diffusion barrier 40, LGP 70, reflectance coating 80, glue frame 50 and following chase 20 and superpose successively, and cancelled black glue 11 in the utility model, the FPC assembly is changed to reverse side by glue frame front; Reduce LED can improve product to the distance of product vision area look really (like lamp holder and dark space bad phenomenon); This adhesive frame structure is simple, and assembling backlight is also fairly simple, and its reflectance coating will not need double faced adhesive tape to fix; To reduce positive black and white double faced adhesive tape; Increase light guide plate, the LED luminous efficiency improves, and has also reduced cost.
Above content is to combine concrete preferred implementation to the further explain that the present invention did, and can not assert that practical implementation of the present invention is confined to these explanations.For the those of ordinary skill of technical field under the present invention, under the prerequisite that does not break away from the present invention's design, can also make some simple deduction or replace, all should be regarded as belonging to protection scope of the present invention.
