Abstract
The invention discloses a novel light guide plate, which comprises a mesh point group and a reflective membrane, wherein the mesh point group is overlapped with the reflective membrane; mesh points in the mesh point group are distributed in a frequency modulation way; and the sizes of the mesh points in the mesh point group are not completely the same as each other. In the novel light guide plate in the scheme of the invention, the mesh point group is overlapped with the reflective membrane, and the mesh points in the mesh point group are distributed in a frequency modulation way, so that Moore interference fringes are not generated, and the picture quality of a backlight module is enhanced.
Description
Technical field
the present invention relates to a kind of LGP, and particularly a kind of novel optic plate that does not produce the Moore interference fringe belongs to capture apparatus component technology field.
Background technology
LGP design concept comes from the LCDs of notebook computer, is the high-tech product that line source is changed into area source.With optical grade acryl (PMMA)/PC is base material; The back light model setting technology of utilization LCD display and notebook computer; See through the high light line conductivity of site (leaded light point), site (leaded light point) calculated, make the LGP light refraction become the equal light state of area source to make moulding through computer.Product adopts spectrophotometry to combine with digital UV printing technology and under constant temperature, constant humidity, dustless environmental baseline, is made, have that ultra-thin, superbright, leaded light are even, energy-saving and environmental protection, no dark space, durable, be difficult for advantages such as yellow, installation and maintenance simple and fast; Shown in accompanying drawing 1; It is consistent that the site crowd's of existing LGP site 1 generally is size; And regular distribution is on the LGP base material; When site crowd and uniform reflective membrane 2 superpositions of coating together the time, Moore will take place interfere and produce the Moore interference fringe, the Moore interference fringe has had a strong impact on the image quality of backlight module.
Summary of the invention
the present invention seeks to for the deficiency that overcomes prior art a kind of novel optic plate that does not produce the Moore interference fringe to be provided.
for achieving the above object, the technical scheme that the present invention adopts is: a kind of novel optic plate comprises site crowd, reflective membrane; Said site crowd and reflective membrane are superimposed; Site among the said site crowd adopts frequency modulation to distribute.
are preferred, each site of said site crowd big or small incomplete same.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Site crowd and reflective membrane are superimposed described in
the present invention program's the novel optic plate; Each site among the said site crowd adopts frequency modulation to distribute, and this programme can not produce the Moore interference fringe, has improved the image quality of backlight module.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Accompanying drawing 1 is the front view of prior art LGP;
Accompanying drawing 2 is the front view of novel optic plate of the present invention;
wherein: 1, site; 2, reflective membrane; 11, site; 12, reflective membrane.
Embodiment
are done further detailed description below in conjunction with accompanying drawing and specific embodiment to the present invention.
are novel optic plate of the present invention like accompanying drawing 2, comprise site crowd, reflective membrane; Said site crowd and reflective membrane 12 are superimposed; Site 11 among the said site crowd adopts frequency modulation to distribute; Each site 11 of said site crowd big or small incomplete same.
Site crowd and reflective membrane are superimposed described in
the present invention program's the novel optic plate; Each site among the said site crowd adopts frequency modulation to distribute, and this programme can not produce the Moore interference fringe, has improved the image quality of backlight module.
More than
only is concrete exemplary applications of the present invention, and protection scope of the present invention is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the rights protection scope of the present invention.
