Fig. 2 shows the schematic diagram of the display device according to this utility model embodiment.Display device 200 includes backlight module and display floater 240.Backlight module is for providing backlight to display floater 240.Display floater 240 shows preferably by lcd technology.Display device 200 also includes the first substrate 250 being positioned on display floater 240 in the present embodiment.First substrate 250 can be the touch base plate that the cover plate of display device 200 can also be provided with touch control electrode.As in figure 2 it is shown, first substrate 250 is provided with the bright zone supplying display floater 240 to carry out showing and the shading region 260 around bright zone.Shading region 260 alternatively, is coated with the ink cabling with covering display floater 240 periphery, and absorbs the light spilt with shield portions backlight module.
Backlight module includes backlight assembly 220 and framework 210.Backlight assembly 220 includes luminous source and the optical module such as light guide plate, reflector plate alternatively.Framework 210 is optionally glue frame.Framework 210 includes the barricade 211 around backlight assembly 220, and barricade 211 extends towards the light direction of backlight assembly 220.Specifically, backlight assembly 220 is towards the light direction that direction is backlight assembly 220 of display floater 240.Barricade 211 is included on the bearing of trend of barricade 211 first 212 of close backlight assembly 220 and away from second 213 of backlight assembly 220 on the bearing of trend of barricade.The inner side of second 213 arranges corner cut structure.Corner cut structure is optionally plane corner cut.In some change case, corner cut structure can also be cambered surface corner cut.This utility model deflects light leak direction by the corner cut structure of second 213 so that reflection light can be blocked district 260 and absorbs or block, and then reduces the light spilt by backlight assembly 220 via framework 210 inner reflection.Alternatively, the inner side of second 213 is provided with ARC and is absorbed into the light being mapped to inside second 213, reduces the light spilt further.
Further, in the present embodiment, the inner side of first 213 is provided with arc groove.Arc groove is towards backlight assembly 220 opening.Arc groove can have less than or equal to 1/2 circle or the arcuate shape less than or equal to 1/2 ellipse.Such as, arc groove can be semicircular in shape.The most such as, arc groove can be the arcuate structure (1/4 circle) with 45 degree of central angles.Similarly, arc groove can also have the arcuate shape of 1/4 ellipse.The inner side of first 213 arranges above-mentioned arc groove, will incide the light back into backlight assembly 220 inside arc groove, and then increases the emitting brightness of backlight assembly 220.Alternatively, the inner side of first 212 has mirror surface structure via mirror process, increases the reflectance inside first 212, and then strengthens the emitting brightness of backlight assembly 220 further.
Specifically, as in figure 2 it is shown, can be directly connected between first 212 and second 213.In other words, upper extreme point inside first 212 and the lower extreme point inside second 213 overlap.In some change case, first 212 and second 213 is passed through the 3rd (not shown), and the inner vertical of the 3rd is in backlight assembly place plane.In other words, the inner side of the 3rd and the external side parallel of barricade 211.It will be understood by those skilled in the art that the 3rd arrange can be in order to adapt to the display floater of differing heights.Such as, when the height of the height of first 212 and second 213 is fixed, but the height sum of first 212 and second 213 much smaller than the height of display floater 240 time, between first 212 and second 213, arrange the 3rd to compensate above-mentioned difference in height.Alternatively, the 3rd inner side can also arrange ARC or arrange absorption/reflection structure, and then reduces the light spilt via the 3rd reflection.

For the sake of clarity, in Fig. 2 and not specifically illustrated display floater, the concrete structure of backlight assembly, and eliminate the members in display device.Those skilled in the art can realize different structure configurations according to different use of display device, does not repeats them here.
Illustrate that the corner cut structure of in this utility model second reduces the principle of light leak below in conjunction with Fig. 3 to Fig. 5.
Showing the local structural graph according to this utility model embodiment referring first to Fig. 3 and Fig. 4, Fig. 3, Fig. 4 shows the light line reflection schematic diagram of Fig. 3.
Such as Fig. 3, distinguish with the cross section (being shown in solid) of the corner cut structure of second 213 in the cross section inside barricade in the prior art shown in phantom parallel with barricade bearing of trend (i.e. Y-direction), with this utility model.
If the light of backlight assembly 220 is via top reflection (as shown in the dotted line parallel with Y-direction) inside the barricade of prior art, and the angle of incidence of its incident ray L is less than or equal to θ0Time, via after the barricade inner reflection shown in the dotted line parallel with Y-direction (vertical direction) but reflection light L1 (shown in dotted line) is not just blocked district 260 and blocks, and then spill.For the structure inside the barricade of prior art, the angle of incidence of incident ray L and reflection light L1 and X-direction (X-direction is the bearing of trend of backlight assembly place plane, the most in horizontal direction) between angle identical.In other words, reflection light L1 is not just blocked district 260 when blocking, the angle theta of reflection light L1 and X-direction0It is exactly the maximum angle θ allowing light and the X-direction spilt0.In other words, θ0Represent the maximum angle allowing light and the backlight assembly place plane spilt.
The corner cut structure of second 213 in this utility model, by the light deflection (namely reflection light L1 counterclockwise deflection) via this corner cut structure inner reflection, and then reflection light can be blocked district 260 and block, reduce the light leakage phenomena of display device 200.In order to illustrate to reflect the lamellar of light, Fig. 4 only illustrates the medial surface M2 of the corner cut structure of second 213 in the medial surface M1 of prior art barricade, the present embodiment and is incided the light path of light of above-mentioned M1 and M2 by backlight assembly.
As shown in Figure 4, according to basic reflection law, when the medial surface M2 of corner cut structure has deflected θ counterclockwise relative to the medial surface M1 of prior art barricade1(the corner cut angle between angle i.e. medial surface M2 and the Y-direction of corner cut structure between the medial surface M2 and the medial surface M1 of prior art barricade of corner cut structure is θ1) time, the reflection light L2 that incident ray L reflects via the medial surface M2 of corner cut structure has deflected 2 θ relative to incident ray L counterclockwise via the reflection light L1 of the medial surface M1 of prior art barricade1(angle between the reflection light L1 and reflection light L2 of same incident ray L is 2 θ1)。
Now, the angle between incident ray L and X-direction is less than or equal to (θ0-2θ1) time, reflection light L2 just can not be blocked district 260 and be blocked and then spill.As can be seen here, the corner cut structure of second 213 has only to less corner cut angle, just reflection light can be made to have bigger deflection, decrease and be not blocked the reflection light blocked in district 260 via the medial surface reflection of corner cut structure, restrained effectively the light leakage phenomena of backlight assembly 220.
Alternatively, θ is worked as0-2θ1When=0, i.e. corner cut angle, θ1=θ0When/2, no matter incident ray L is incident with which kind of angle, and reflection light L2 can be blocked district 260 and block.Work as θ1>θ0/ 2, it is also possible to reach same effect.Therefore, when corner cut angle, θ1≥θ0When/2, it prevents from reflecting the effect optimum that light spills.
Specifically, it is allowed to the reflection light spilt and the maximum angle θ of X-direction0Can calculate according to the height h of corner cut structure, θ0=actan (h/a).Wherein, a represents the length (seeing Fig. 3) of minimum clearance between barricade 211 and display floater 240.In other words, a represents the length in the gap between first 212 and second 213 joint and display floater 240.Further, according to above-mentioned formula, the height h=atan θ of corner cut structure0.Meanwhile, corner cut angle, θ can also be obtained according to above-mentioned formula1And relation between length a of minimum clearance between the height h of corner cut structure and barricade 211 and display floater 240, such as, θ1≥1/2actan(h/a).As it has been described above, corner cut structure is optionally plane corner cut or cambered surface corner cut.In other words, if corner cut structure is plane corner cut, the corner cut angle, θ between corner cut structure and vertical direction1≥1/2θ0.Minimum corner cut angle, θ if corner cut structure is cambered surface corner cut, between corner cut structure and vertical direction1≥1/2θ0。
Further, with reference to Fig. 5, the corner cut structure panning effect to reflection light is described.Fig. 5 shows the schematic diagram reflecting light translation at the backlight module second according to this utility model embodiment.When incident ray L is with the medial surface A of any incident angle θ directive corner cut structure1B, and intersect at C point.This incident ray L and vertical A0B intersects at D point.(its medial surface is by A to assume another corner cut structure0D illustrates) lower extreme point be D point, A0D and A1The inclination angle of B is identical is all θ1, via A0D reflection reflection light L3 and via A1The reflection light L4 of B reflection is parallel.In the embodiment shown in fig. 5, its corner cut structure medial surface is A1The intersection point of B, incident ray L and reflection light L4 is C, and therefore, relative reflection light L3, reflection light L4 translates to shading region 260, makes reflection light be easier to be blocked.From geometrical relationship, distance X of reflection light level direction translationCD=(YBDsinθsinθ1)/(cos(θ+θ1).Wherein, YBDLength for BD end.
As can be seen here, the corner cut structure of this utility model second not only reduces the scope of angle between the incident ray and X-direction that can spill, but also is to make reflection light translate to the left, it is easier to is blocked, thus effectively reduces light leak.
The light principle of reflection of this utility model backlight module first is described below in conjunction with Fig. 6.Fig. 6 shows the schematic diagram reflecting light at the backlight module first according to this utility model embodiment.
In figure 6, distinguish with the cross section (being shown in solid) of the arc groove of first 212 in the cross section inside barricade in the prior art shown in phantom parallel with barricade bearing of trend, with this utility model.
When barricade inner reflection during the incident ray L that angle of incidence is θ is via prior art, the angle between its reflection light L1 and incident ray L is 2 θ.When incidence angle θ constantly increases, the angle between reflection light L1 and incident ray L the most constantly increases, and the probability that reflection light L1 spills also is increased by.
And in the present embodiment, if incident ray L incides inside arc groove, incidence angle θ ' less than above-mentioned incidence angle θ, the probability that reflection light L2 spills is substantially reduced.Meanwhile, according to the shape of arc groove, reflection light L2 penetrates towards backlight assembly 220, improves the emitting brightness of backlight assembly 220.
Alternatively, the radius of curvature of the arcuate shape of arc groove is gradually increased towards backlight assembly.In other words, close to the upper extreme point of arc groove with the intersection point of arc groove along with incident ray, reflection light L2 also can be the closer to incident ray L.Also just say that reflection light L2 can return among backlight assembly 220 along input path.The escape effectively reducing reflection light the most further spills, and can also improve the emitting brightness of backlight assembly.
It will be appreciated by those skilled in the art that, due to the light spilt through different interface multiple reflections, reflex strength is the least, less on light leak impact, therefore, the principle that the inhibitory reflex light of above-mentioned Fig. 3 to Fig. 6 spills only describes the light the most directly reflected via framework 210.
With reference to Fig. 7 to Fig. 9, different embodiment of the present utility model is described the most respectively.
Fig. 7 shows the schematic diagram of the backlight module 300 according to another embodiment of this utility model.In the figure 7, it is corner cut structure inside second 313 of the barricade 311 of framework 310, and parallel with the lateral wall of barricade 311 inside first 312.The phenomenon that the framework 310 of the backlight module 300 shown in Fig. 7 is only spilt after reflection by the light of the corner cut structure suppression backlight assembly 320 of second 313.Such backlight module 300 is relatively simple on making technology.
Fig. 8 shows the schematic diagram of the backlight module 400 according to the another embodiment of this utility model.In fig. 8, the corner cut structure inside second 413 is cambered surface corner cut.The processing procedure being designed with beneficially framework 410 of cambered surface corner cut.The schematic diagram of the corner cut structure shown in Fig. 8 is shown with further reference to Fig. 9, Fig. 9.In conjunction with the light principle of reflection of Fig. 3 and Fig. 4, the minimum corner cut angle, θ when corner cut structure is cambered surface corner cut, between corner cut structure and barricade 410 bearing of trend (vertical direction)1≥1/2θ0So that cambered surface corner cut prevents from reflecting the effect optimum that light spills.θ0With Fig. 3 and Fig. 4 described in identical, represent and allow the maximum angle of light and the backlight assembly place plane spilt.
Above-mentioned Fig. 2 to Fig. 9 only schematically shows principle of the present utility model and multiple different embodiment; those skilled in the art can realize the change of more structure according to the description of description; these changes, all in protection domain of the present utility model, do not repeat them here.
