Abstract
The utility model relates to a light guide plate which comprises a light inlet surface, a bottom surface and a light outlet surface, wherein the bottom surface is crossed with the light inlet surface, the light outlet surface is opposite to the bottom surface, and a light guide microstructure layer is arranged on the light inlet surface. According to the light guide plate, the light inlet surface is provided with the light guide microstructure layer, the phenomenon of picture fireflies is solved, stability of processing technology is high, the technology is simple, and operation is convenient.
Description
Technical field
The utility model relates to a kind of LGP.
Background technology
At present, for small-sized, thinner backlight module, adopt LED side-light type illumination, wherein the LGP structure that is absolutely necessary more.The incidence surface of existing LGP is usually done mirror finish and is processed, less than normal because of the light inlet angle when LED light enters, cause picture the firefly phenomenon to occur, such as the need head it off, existing scheme is must increase LED quantity or increase LGP to glue frame distance, causes cost and energy consumption to rise.
The utility model content
The purpose of this utility model is to overcome the defective that prior art exists, and provides a kind of incidence surface to have the LGP of leaded light microstructured layers.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of LGP, the bottom surface of comprise incidence surface, intersecting with incidence surface and the exiting surface relative with the bottom surface are provided with the leaded light microstructured layers on the described incidence surface.
Described leaded light microstructured layers is arranged in array by several strip micro-structurals by same direction.
The cross section of described strip micro-structural is polygon, and its apex height is 15～100um, and the spacing between the two adjacent strip micro-structural summits is 30～200um.
The cross section of described strip micro-structural is triangle, and its apex height is 15～100um, and the spacing between the two adjacent strip micro-structural summits is 30～200um.
The cross section of described strip micro-structural is semicircle, and its apex height is 15～100um, and the spacing between the two adjacent strip micro-structural summits is 30～200um.
Beneficial effect: the incidence surface at LGP increases the leaded light microstructured layers, is added to the optic angle degree when LED light is entered, and has solved picture firefly phenomenon, and can reduce by LED number, has saved cost and energy consumption.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of the preferred embodiment three of LGP.
Wherein: 1, incidence surface; 1-1, strip micro-structural; 2, bottom surface; 3, exiting surface.
The specific embodiment
A kind of LGP as shown in Figure 1, the bottom surface 2 that comprises incidence surface 1, intersects with incidence surface 1 and the exiting surface 3 relative with bottom surface 2, be provided with the leaded light microstructured layers on the described incidence surface 1, this leaded light microstructured layers is arranged in array by several strip micro-structurals 1-1 by same direction.
Preferred embodiment one: the cross section of described strip micro-structural 1-1 is polygon, and its apex height is 15～100um, and the spacing between the two adjacent strip micro-structural summits is 30～200um.
Preferred embodiment two: the cross section of described strip micro-structural 1-1 is triangle, and its apex height is 15～100um, and the spacing between the two adjacent strip micro-structural summits is 30～200um.
Preferred embodiment three: the cross section of described strip micro-structural 1-1 is semicircle, and its apex height is 15～100um, and the spacing between the two adjacent strip micro-structural summits is 30～200um.
Should be appreciated that specific embodiment described above only is used for explaining the utility model, and be not used in restriction the utility model.The apparent variation of being extended out by spirit of the present utility model or change still are among the protection domain of the present utility model.
