Below will specify above technology contents further to illustrate the technical characterictic of this case with a plurality of embodiment.
Please continue to consult shown in Figure 1A and Figure 1B.In order to make drawing succinct, at this lighting angle that omits luminescence component 510, only present its main emergent shaft A and related side to light.The end face 310 of light guide plate 200 is pentagon, and comprises hypotenuse sidewall 323 and two relative minor face sidewalls 322 that a long side wall 321, two is adjacent.This long side wall 321 is positioned at one of plate body 300 side, and between this two minor faces sidewall 322.This two hypotenuses sidewall 323 is at the opposite side of plate body 300 and between this two minor faces sidewall 322.Especially, because this two hypotenuses sidewall 323 (for example has one first angle Θ 1 with the axis of reference N of a parallel long avris wall 321 respectively, the 6-10 degree), meaning is to have an obtuse angle greater than 90 degree between this two hypotenuses sidewall 323, so, as can be known this two hypotenuses sidewall 323 respectively with all the other sidewall, promptly long side wall 321 and minor face sidewall 322 irrelevancies are capable.So in the present embodiment, arbitrary hypotenuse sidewall 323 itself promptly can be one first reflecting slant, can reflect interior the light of plate body 300 to a plurality of or at least one leaded light block 311 remedying the deficiency of its glorious degrees, and then the uniformity coefficient of lifting light.
In addition, light guide plate 200 also can be considered a plate body 300 and has a reflecting part 400.Reflecting part 400 for example is single outstanding lamellar body 410, is that can to present the side of its thickness towards plate body 300 outstanding, and one-body molded with plate body 300.Outstanding lamellar body 410 has two adjacent hypotenuse sidewalls 323 (i.e. first reflecting slant), and this is that hypotenuse sidewall 323 forms the angle of one first deflection angle, 420, the first deflection angles 420 greater than 90 degree; Meaning be this be a bit between the hypotenuse sidewall 323 angle greater than 90 the degree.So, arbitrary is that hypotenuse sidewall 323 can reflect the interior light of plate body 300 to a plurality of or at least one leaded light block 311.
During one of present embodiment changed, light guide plate 200 more comprised a reflection horizon 430.It is surface outside the hypotenuse sidewall 323 (i.e. first reflecting slant) that reflection horizon 430 is positioned at this, to reflect light whole in the plate body 300 to a plurality of or at least one leaded light block 311.Even reflection horizon 430 also can be positioned at surperficial (not shown) outside all above-mentioned sidewalls.Reflection horizon 430 for example is reflector plate, reflection glue or reflection microstructure.
See also shown in Fig. 2 A and Fig. 2 B.In order to make drawing succinct, at this lighting angle that omits luminescence component 510, only present its main emergent shaft A and related side to light.
In Fig. 2 A, these a little sidewalls for example can be divided into a long side wall 331, two relative minor face sidewall 332 and a plurality of hypotenuse sidewall 333.This long side wall 331 is positioned at one of plate body 300 side, and between this two minor faces sidewall 332.The adjacent in regular turn and indentation of these a little hypotenuse sidewalls 333 is arranged in the side in addition of plate body 300, and between this two minor faces sidewall 332.At this long side wall 331, minor face sidewall 332 and hypotenuse sidewall 333 is to be used for the explanation diagram, is not that oppose side wall is done a qualification.
Especially, because the axis of reference N of an arbitrary hypotenuse sidewall 333 and a parallel long avris wall 331 (for example has one second angle Θ 2, the 10-15 degree), has an obtuse angle greater than 90 degree between the meaning promptly wantonly two hypotenuse sidewalls 333 that join, so, as can be known these a little hypotenuse sidewalls 333 respectively with all the other sidewall, promptly long side wall 331 and minor face sidewall 332 irrelevancies are capable.So arbitrary hypotenuse sidewall 333 itself promptly can be one second reflecting slant, can reflect plate body 300 interior light and arrive at least one leaded light block 311.Particularly, each second angle Θ 2 can be inequality, makes interior the light of angle reflection plate body that each second reflecting slant (being hypotenuse sidewall 333) can difference 300 to the leaded light block 311 of correspondence, improving its glorious degrees, and then the uniformity coefficient of lifting light.
In addition, light guide plate 200 also can be considered a plate body 300 and has a reflecting part 401 in 2A figure.Reflecting part 401 for example is the outstanding lamellar body 410 of a plurality of indentation arrangements, and this outstanding a bit lamellar body 410 is that can to present the side of its thickness towards plate body 300 outstanding, and one-body molded with plate body 300.Each outstanding lamellar body 410 has two second reflecting slant (being hypotenuse sidewall 333).2 second reflecting slant of each outstanding lamellar body 410 (being hypotenuse sidewall 333) can form the angle of one second deflection angle, 421, the second deflection angles 421 greater than 90 degree; Meaning is that the angle between these a little second reflecting slant (being hypotenuse sidewall 333) is spent greater than 90.So, arbitrary second reflecting slant (being hypotenuse sidewall 333) can reflect the interior light of plate body 300 to a leaded light block 311 wherein, remedying the deficiency of its glorious degrees, and then promotes the uniformity coefficient of light.
During one of present embodiment changed, light guide plate 200 more comprised a reflection horizon 431.Reflection horizon 431 is positioned at surface outside all second reflecting slant, to reflect light whole in the plate body 300 to a plurality of or at least one leaded light block 311.Even reflection horizon 431 is positioned at surperficial (not shown) outside all sidewalls.Reflection horizon 431 for example is reflector plate, reflection glue or reflection microstructure.
See also shown in Fig. 3 A and Fig. 3 B.In order to make drawing succinct, at this lighting angle that omits luminescence component 510, only present its main emergent shaft A and related side to light.
End face 310 (being exiting surface) is roughly rectangular, and the sidewall of rectangle is two relative long side wall 341 and two relative minor face sidewalls 342.This two long sides wall 341 and minor face sidewall 342 have a plurality of unfilled corners 422 respectively, and these a little unfilled corners 422 have the 3rd reflecting slant 423 of inclination in the plate body 300 on one day respectively.The axis of reference N of a reflecting slant and a parallel long avris wall 341 has one the 3rd angle Θ 3 (for example, 30～65 degree), and meaning is this 3rd reflecting slant 423 and the sidewall of all the other, and promptly long side wall 341 and minor face sidewall 342 irrelevancies are capable.At this long side wall 341, minor face sidewall 342 is to be used for the explanation diagram, is not that oppose side wall is done a qualification.
The designer can be in response to configuration unfilled corner 422 under the practical situation at the faint a certain leaded light block 311 of long side wall 341 corresponding light fields, make the 3rd reflecting slant 423 of unfilled corner 422 can reflect the interior light of plate body 300 leaded light block 311 so far, to remedy the deficiency of its glorious degrees.For example, since luminescence component 510 back to the light that can accept of leaded light block 311 limited, so wherein a unfilled corner 422A is configurable in the position of long side wall 341 near luminescence component 510, the 3rd reflecting slant 423 of this unfilled corner 422A can reflect the interior light of plate body 300 to 510 of luminescence components back to a wherein leaded light block 311, and then improve the glorious degrees of this leaded light block 311.Again for example, because some leaded light blocks 311 contiguous minor face sidewalls 342 and away from the main light-emitting axis A of luminescence component 510, make the light ray energy deficiency that these a little leaded light blocks 311 can be accepted, so wherein another unfilled corner 422B is configurable in the corner of long side wall 341 near minor face sidewall 342, make the 3rd reflecting slant 423 of unfilled corner 422B can reflect the leaded light block 311 of the interior light of plate body 300, and then improve the glorious degrees of this leaded light block 311 to correspondence.
In addition, light guide plate 200 also can be considered a plate body 300 and has a reflecting part 402 in Fig. 3 A.Reflecting part 402 for example is above-mentioned unfilled corner 422.Unfilled corner 422 is formed at the long side wall 341 or the minor face sidewall 342 of plate body 300 one-body moldedly.
During one of present embodiment changed, light guide plate 200 more comprised a reflection horizon 432.Reflection horizon 432 is positioned at surface outside the 3rd reflecting slant 423, to reflect light whole in the plate body 300 to a plurality of or at least one leaded light block 311.Even the reflection horizon can be positioned at surperficial (not shown) outside all sidewalls.Reflection horizon 432 for example is reflector plate, reflection glue or reflection microstructure.
Among above-mentioned each embodiment of the present invention, backlight module 100 can be applicable to key board unit, and these a little leaded light blocks 311 are provided with in response to the correspondence position of keyboard respectively, so that the luminous pattern of corresponding keyboard to be provided.Yet the present invention's backlight module 100 is not limited in key board unit.
