Abstract

The utility model discloses a kind of light conducting plate structure and backlight module.For the utility model by being spaced setting groove structure and broached-tooth design, dispersion angle of the increasing light in light guide plate on light guide plate incidence surface, make light guide plate goes out light more evenly.Increase groove structure in LED light mouth to increase light mixing distance, and the light that socket is concentrated is distributed to other directions, lamp eye problem is solved, in particular for the short light path lamp eye problem in narrow frame backlight module.

Description

A kind of light conducting plate structure and backlight module

Technical field

The utility model relates to Liquid Crystal Module field more particularly to a kind of light conducting plate structures.

Background technique

Light guide plate is the important component in LCD backlight module system.It is guidance dispersion point light source that it, which is acted on, Or the light that linear light source issues is area source, while improving the uniformity of panel luminous gray scale and light emission luminance.In side entrance back In mould group, the side of light guide plate is arranged in light source, and light enters light guide plate from the side of light guide plate, and light dissipates illuminate through the light guide plate Display screen.The incident side end face of existing light guide plate (please referring to Fig. 4) be equipped with it is several towards light guide plate input light source LED light, every two Between adjacent LED light, the light source of output can generate angle because of the relationship of angle of beam, form so-called penumbra area, and LED light Mouth light is concentrically formed lamp eye, causes visual effect poor.Some are by the way that interval ink, the modes gram such as hollow glue are arranged on FPC Lamp eye problem is taken, but FPC is not to be setting in light-emitting window in cob lamp bar, but is located at side, it cannot be by setting oil on FPC Ink solves the problems, such as this.Also by illuminator with light guide plate light inputting end identity distance from widening, the generation of dark space or lamp eye can be overcome, but In this way increase space shared by light guide plate and illuminator, influences to shield accounting.Present liquid crystal display, backlight module are all toward narrow side Frame, high screen accounting develop, and the short light path lamp eye problem and dark space in backlight module become apparent.

Therefore, the prior art is defective, needs to improve.

Utility model content

The purpose of the utility model is to overcome the deficiencies in the prior art, a kind of light conducting plate structure and backlight module are provided, fitted For improving the uniformity of panel luminous gray scale and light emission luminance, overcomes the generation of dark space or lamp eye, adapt to narrow frame liquid crystal Show, the development of backlight module mould group.

The technical solution of the utility model is as follows: providing a kind of light conducting plate structure, comprising: light guide plate, LED light, it is described to lead The light incident sides of tabula rasa are provided with several groove structures and several broached-tooth designs.

Further, the groove structure and the broached-tooth design interval are arranged, and the groove structure is arranged in the LED Light guide plate incidence surface is arranged in the region in addition to the groove in lamp corresponding position, the broached-tooth design.

Further, the width w of the single groove structure are as follows: width < w of single led lamp half < single led lamp Width.

Further, the width of the single groove structure is greater than the width of single broached-tooth design, the single groove knot The height of structure is greater than the height of single broached-tooth design.

Further, the groove structure shape is triangle, trapezoidal or arc-shaped.

Further, the broached-tooth design shape is semicircle or triangle.

The utility model also provides a kind of backlight module, including light conducting plate structure as described above.

Using the above scheme, the utility model on light guide plate incidence surface by being spaced setting groove structure and sawtooth knot Structure, dispersion angle of the increasing light in light guide plate, make light guide plate goes out light more evenly.LED light mouth increase groove structure with Increase light mixing distance, and the light that socket is concentrated is distributed to other directions, lamp eye problem is solved, in particular for narrow frame backlight Short light path lamp eye problem in mould group.

Fig. 1 is the utility model triangular groove structural schematic diagram.

Fig. 2 is the utility model trapezoidal groove structural schematic diagram.

Fig. 3 is the utility model circular groove and semicircle broached-tooth design schematic diagram.

Fig. 4 is existing light conducting plate structure schematic diagram.

Specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.

It please refers to Fig.1 to Fig.3, the utility model provides a kind of light conducting plate structure, comprising: light guide plate 100, LED light 200. The light incident sides of the light guide plate are provided with several groove structures 110 and several broached-tooth designs 120.The utility model passes through setting The dispersion angle of groove structure 110,120 increasing light of broached-tooth design in light guide plate 100, make light guide plate goes out light more evenly.

The groove structure 110 is arranged with the broached-tooth design 120 interval, and the groove structure 110 is arranged in the LED 110 incidence surface of light guide plate is arranged in addition to the groove structure 110 in the corresponding position of 200 socket of lamp, the broached-tooth design 120 In region.Groove structure 110 is set in 200 socket of LED light to increase light mixing distance, and the light that socket is concentrated can be distributed to Other directions solve lamp eye problem, especially for the short light path lamp eye problem in narrow frame backlight module.

The width w of the single groove structure 110 are as follows: width < w < single led lamp 200 of single led 200 half of lamp Width, to guarantee the light-out effect of light guide plate.The width of the single groove structure 110 is greater than the width of single broached-tooth design 120 The height of degree, the single groove structure 110 is greater than the height of single broached-tooth design 120.

110 shape of groove structure is triangle (as shown in Figure 1), trapezoidal (as shown in Figure 2) or arc-shaped (such as Fig. 3 It is shown).120 shape of broached-tooth design is semicircle or triangle.

In conclusion the utility model is by being arranged groove structure and broached-tooth design in LED light mouth, hence it is evident that increasing light exists Dispersion angle in light guide plate increases light mixing distance, solves dark space or lamp eye problem, makes the light-out effect of light guide plate more evenly, It is particularly suitable for narrow frame backlight module.

The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all practical at this Made any modifications, equivalent replacements, and improvements etc., should be included in the guarantor of the utility model within novel spirit and principle Within the scope of shield.
