Fig. 1 is the partial cutaway schematic of the backlight module of one embodiment of the invention.Fig. 2 is the upward view of the diffuser plate of the backlight module of Fig. 1.Refer to Fig. 1, the backlight module 100 of the present embodiment includes multiple light-emitting component 110, multiple lens 120, backboard 130, diffuser plate 140 and a reflector element 150.For example, in the present embodiment, light-emitting component 110 is such as light emitting diode, but the invention is not restricted to this, and other point source being suitable for also can as light-emitting component 110.Specifically, as it is shown in figure 1, light-emitting component 110 is configured on backboard 130, and for providing a light beam 60 respectively.Reflector element 150 is configured on backboard 130, and is positioned at the periphery of light-emitting component 110.Additionally, each lens 120 are correspondingly arranged in the top of each light-emitting component 110.
More specifically, in the present embodiment, lens 120 can with so that the light beam 60 that light-emitting component 110 provides further be dispersed, so that light beam 60 is respectively after by lens 120, the dispersion angle of light beam 60 is variable greatly, say, that the regional extent that light beam 60 is radiated at diffuser plate 140 can be made to become big.When the regional extent that light beam 60 is radiated at diffuser plate 140 becomes big, when reducing diffuser plate 140 relative to desired spacing H (i.e. the light mixing distance) of light-emitting component 110, will can remain to possess the preferably light uniformity.So, will can be effectively reduced the integral thickness of backlight module 100 and the preferably light uniformity is provided simultaneously.
On the other hand, as shown in Figures 1 and 2, in the present embodiment, diffuser plate 140 is arranged at the top of these lens 120, diffuser plate 140 has an a relative surface S1 and surface S2, wherein the surface S1 of diffuser plate 140 is an incidence surface, and surface S2 is an exiting surface, and is such as an exiting surface of backlight module 100.Diffuser plate 140 is provided with multiple site block PR on the surface S1 of lens 120.Specifically, these sites block PR has multiple site NP.Specifically, in the present embodiment, the corresponding each light-emitting component 110 of each site block PR, and the C1 position, center of each site block PR is corresponding to the C2 position, center of each light-emitting component 110.More specifically, as in figure 2 it is shown, in the present embodiment, each site block PR includes multiple sub-network block PS.And, the sub-network block PS of each site block PR includes one first sub-network block PS1 and one second sub-network block PS2, wherein the first sub-network block PS1 is positioned at the C1 position, center of site block PR, and the second sub-network block PS2 is ring-type, and around the first sub-network block PS1.
In the present embodiment, the size of the site NP of backlight module 100 is identical, and for example, the size of site NP drops on be more than or equal to 0.1mm and less than or equal between 1.0mm, to avoid site NP can arrive observed by user.It should be noted that numerical range herein is all only as the use illustrated, it is not limited to the present invention.Specifically, in the present embodiment, by site NP being arranged at diffuser plate 140 towards on the surface S1 of lens 120, by partially reflective for light beam 60, and the bright dizzy problem of backlight module 100 can be eliminated, to provide the preferably light uniformity.
Furthermore, in the present embodiment, backlight module 100 can spread light beam 60 to provide the light uniformity preferably mode is that the distribution density utilizing site NP is reached.For example, owing to the C1 position, center of site block PR each on diffuser plate 140 can relatively closer light-emitting component 110, its light intensity receiving light beam 60 is higher, therefore can by being bigger along the C2 position, center (or the C1 position, center near site block PR) near corresponding light-emitting component 110 by the density design of site NP.In addition, the light beam 60 that sends due to light-emitting component 110 as the reflection of lens 120, refraction action and produce bright band at diffuser plate 140, therefore the site NP density design in bright band region (in the present embodiment, being the scope of the second sub-network block PS2) can also be corresponded on diffuser plate 140 for bigger.
For example, as shown in Figure 2, in the present embodiment, be positioned at the density of the site NP of the first sub-network block PS1 be along the C1 position, center away from site block PR direction decrescence after, cumulative toward the second sub-network block PS2 again, and the density being positioned at site NP peripheral for the second sub-network block PS2 be along the C1 position, center away from site block PR direction decrescence.It is to say, the first sub-network block PS1 relative with the C2 position, center of each light-emitting component 110 on diffuser plate 140, received light beam 60 is comparatively concentrated, and therefore, is bigger by the site NP density design of the first sub-network block PS1.On the other hand, the second sub-network block PS2 on diffuser plate 140 corresponds to bright band region, and its site NP density design is maximum.And the sub-network block PS3 between the first sub-network block PS1 and the second sub-network block PS2 is more weak due to its accepted beam intensity, therefore its site NP density is smaller than the first sub-network block PS1 and the site NP density of the second sub-network block PS2.In like manner, be positioned at sub-network block PS4 peripheral for the second sub-network block PS2 due to its accepted beam intensity more weak, therefore its site NP density is also designed to less.Consequently, it is possible to backlight module 100 is bright dizzy by being eliminated by the site NP density of regulation and control different sub-network point block PS, and it is provided that the preferably light uniformity.
More specifically, in the present embodiment, the material of site NP is different from the material of diffuser plate 140, and wherein site NP can adopt the mode of printing to be formed on diffuser plate 140, and therefore the material of site NP can be the material of ink etc.For example, in the present embodiment, the material of site NP includes white ink, Yellow ink, blue ink or black ink, and can be further directed to the brightness of picture and taste is adjusted.
Furthermore, owing to light beam is via after the NP scattering of site, it will the colour cast problem of picture occurs, therefore, in the present embodiment, site NP mixed with the diffusion particle of different colours, in order to diffuse through light beam therein, and can adjust the colour cast problem of picture.For example, when site NP is only with the material of white ink, corresponding to the picture of the first sub-network block PS1 it would appear that the phenomenon that color is partially yellow then can occur because of the dispersion of light beam and decay in the partially blue picture corresponding to the second sub-network block PS2 of color in backlight module 100, therefore, in the present embodiment, the site NP of at least two sub-network block PS has different colours, to adjust the picture colour cast problem in zones of different of backlight module 100, and then overall picture taste can be improved.
Furthermore, in the present embodiment, the site NP of the first sub-network block PS1 includes multiple first color diffusion particle, and the site NP of the second sub-network block PS2 includes multiple second color diffusion particle.More specifically, in the present embodiment, the first color diffusion particle is yellow diffusion particle, and the second color diffusion particle is blue diffusion particle.So, to be able to be adjusted in the colour cast of zones of different for the picture of backlight module 100, eliminate original picture corresponding to the first sub-network block PS1 and occur that the color offset phenomenon that color is partially yellow then occurs in the partially blue picture corresponding to the second sub-network block PS2 of color, and then reach good picture taste.And when adding black ink in the site NP material of different sub-network point block PS, due to black ink can absorption portion light beam to reduce brightness, therefore will can be adjusted for the brightness of picture zones of different by interpolation black ink in the NP material of site, and then good picture taste can be reached.
It should be noted that in the foregoing embodiments, the size of the site NP of each site block PR of backlight module 100 is all identical, but utilizes the distribution density adjusting site NP to reach the good light uniformity and picture taste, but the invention is not restricted to this.In other embodiments, it is possible to make the site NP of each site block PR on diffuser plate 140 be of different sizes size along with diverse location, and reach the good light uniformity and picture taste.Hereinafter collocation Fig. 3 is explained orally further.
