Abstract
The utility model discloses a new type light guide plate. The new type light guide plate includes a net-node group and a reflective film. The net-node group and the reflective film are superposed together. The net-nodes in the net-node group are in frequency modulation distribution. The sizes of the net-nodes in the net-node group are not exactly the same. According to the new type light guide plate in the technical scheme of the utility model, the net-node group and the reflective film are superposed together, and the net-nodes in the net-node group are in frequency modulation distribution, so according to the technical scheme, no moore interference fringe will be generated, so that the image quality of a backlight module is improved.
Description
Technical field
The utility model relates to a kind of light guide plate, and particularly a kind of light guide plate that does not produce the Moore interference fringe belongs to capture apparatus component technology field.
Background technology
The light guide plate design concept comes from the LCDs of notebook computer, is the high-tech product that line source is changed into area source.Be base material with optical grade acryl (PMMA)/PC, use the back light model setting technology of LCD display and notebook computer, see through the high light line conductivity of site (light guiding points), through computer site (light guiding points) calculated, make the light guide plate light refraction become the equal light state of area source to make moulding.Product adopts spectrophotometry to combine with digital UV printing technology and is made under constant temperature, constant humidity, dustless environmental baseline, have that ultra-thin, superbright, leaded light are even, energy-saving and environmental protection, no dark space, durable, be difficult for the advantages such as yellow, installation and maintenance simple and fast; As shown in Figure 1, the site group's of existing light guide plate site 1 generally is in the same size, and regular distribution is on the light guide plate base material, when site group and uniform reflective membrane 2 superpositions of coating together the time, the Moore interference will occur and produce the Moore interference fringe, the Moore interference fringe has had a strong impact on the image quality of backlight module.
The utility model content
The utility model purpose is that a kind of light guide plate that does not produce the Moore interference fringe is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of light guide plate comprises site group, reflective membrane; Described site group and reflective membrane are superimposed; Site among the described site group adopts frequency modulation to distribute.
Preferably, each site of described site group is big or small incomplete same.
Because the utilization of technique scheme, the utility model compared with prior art has following advantages:
Site group and reflective membrane are superimposed described in the light guide plate of the utility model scheme; Each site among the described site group 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 solutions of the utility model are described further:
Accompanying drawing 1 is the front view of prior art light guide plate;
Accompanying drawing 2 is the front view of light guide plate described in the utility model;
Wherein: 1, site; 2, reflective membrane; 11, site; 12, reflective membrane.
Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Be light guide plate described in the utility model such as accompanying drawing 2, comprise site group, reflective membrane; Described site group and reflective membrane 12 are superimposed; Site 11 among the described site group adopts frequency modulation to distribute; Each site 11 of described site group big or small incomplete same.
Site group and reflective membrane are superimposed described in the light guide plate of the utility model scheme; Each site among the described site group adopts frequency modulation to distribute, and this programme can not produce the Moore interference fringe, has improved the image quality of backlight module.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
