Detailed description of the invention
For making those skilled in the art be more fully understood that technical scheme, come the present invention below in conjunction with the accompanying drawings
The backlight module and the display device that there is provided are described in detail.
The structural representation of the backlight module that Fig. 1 provides for the embodiment of the present invention.Referring to Fig. 1, backlight module includes the back of the body
Light source 1 and liquid crystal lens 2.Wherein, backlight 1 emits beam towards the direction of display module 3 through liquid crystal lens 2.This backlight
The light that source 1 sends has the fixing angle of divergence, and this angle of divergence can the most freely set.Liquid crystal lens 2 is not
During work (i.e. no power), only make the light sent by backlight 1 pass through, and do not change the angle of divergence of this light.Liquid crystal lens 2
When work (i.e. energising), equivalence forms concavees lens, in order to increase by the backlight of the object distance position being positioned at these concavees lens
The angle of divergence of the light that source 1 sends.
The angle of divergence size of the light sent due to backlight 1 determines the visual range of display module 3, i.e. the angle of divergence
The biggest, then visual range is the biggest；Otherwise, the angle of divergence is the least, then visual range is the least, therefore, by making liquid crystal lens 2 in work
And do not work and switch between two states, it is possible to achieve switch between two different visual ranges, thus can
To increase the motility of visual effect.Such as, according to the less angle of divergence, then when liquid crystal lens 2 does not works, show module
The visual range of 3 is less, such that it is able to realize the visual effect of peep-proof.And when liquid crystal lens 2 works, at liquid crystal lens 2
Under disperse function, display module 3 is switched to bigger visual range from original visual range, such that it is able to what realization was shared
Visual effect.
Duty is entered, it is preferred that by adjusting by i.e. realizing liquid crystal lens 2 to liquid crystal lens 2 load driver voltage
Save this driving voltage, can make liquid crystal lens 2 equivalence formed different curvature radius concavees lens, such that it is able to formed more kinds of can
Depending on scope, improve the motility of visual effect further.Such as, the radius of curvature of concavees lens can be 49 μm, 25 μm, 17 μm,
13 μm, 11 μm or 9.8 μm etc..As shown in Figure 4, sending out of the light for the concavees lens of different curvature radius, backlight sent
Dissipate the concrete datagram of effect.As seen from the figure, when liquid crystal lens 2 does not works, the radius of curvature of concavees lens is infinitely great, now
The angle of divergence of the light sent by backlight 1 (that is, former angle) is that +/-30 ° is (using the 5% of the original brightness of backlight as regarding
Angle benchmark).When liquid crystal lens 2 works, its equivalence the radius of curvature of concavees lens formed be respectively 49 μm, 25 μm, 17 μm,
13 μm, 11 μm or 9.8 μm.Under the effect of liquid crystal lens 2, backlight 1 the new angle of divergence of the light sent, new brightness with
And the concrete data of the new visual range (Range) finally obtained are as shown in Figure 4, it is achieved thereby that multiple different visual model
Enclose.
It is further preferred that according to human eye relative to the diverse location of viewing area, regulate the radius of curvature of concavees lens, from
And suitable visual range can be selected more accurately.This viewing area is the viewing area of display module 3.Such as, display
Region includes center and marginal position, and wherein, when human eye is near center, required visual range is less, and works as
Human eye is when marginal position, and required visual range is relatively big, based on this, when human eye is near center, can use relatively
The radius of curvature of big concavees lens；When human eye is near marginal position, the radius of curvature of less concavees lens can be used, i.e.
Make the radius of curvature curvature half more than human eye concavees lens when marginal position of human eye concavees lens when center
Footpath, such that it is able to meet the demand of user more accurately.It should be noted that in actual applications, can use existing
Human eye tracer technique determines the human eye position relative to viewing area.
When setting the relevant parameter of liquid crystal lens 2, the retardation Δ nd of such as liquid crystal cell, wherein, d is the box of liquid crystal cell
Thick；Δ n is birefringence, equal to ne-n0, neFor the normal refraction rate of liquid crystal cell, n0For the abnormal refraction rate of liquid crystal cell, permissible
