Abstract
The utility model discloses a light guide plate. The light guide plate comprises a light guide plate body, wherein a side edge of the light guide plate body is provided with a plurality of LED lamps, a central position of the light guide plate body is provided with main network points, the main network points comprise a plurality of circular points, dimensions of the circular points increase gradually in a direction departing the LED lamps, the side edge of the light guide plate body near the LED lamps is provided with two rows of auxiliary network points having irregular dimensions, and the auxiliary network points are circular or square. According to the light guide plate, non-uniform brightness is meliorated in a mode employing the decoration network points, the light guide plate further has properties of substantially obvious effects, simple operation and low cost.
Description
Technical field
The utility model belongs to the light guide plate product scope, particularly the better light guide plate of a kind of light guide effect.
Background technology
The display effect of backlight module can affect the display effect of liquid crystal module usually, wherein one comparatively distinct issues be the light and shade uneven phenomenon easily to occur near LED lamp one side, and then the leaded light that affects light guide plate shows, in order to address this problem, someone has proposed the increase Tp and has improved this situation, Tp can address the above problem, but also there is certain problem, Tp is shaped by Mould Machining, cost is high, processing difficulties, and can only use on the small size light guide plate, large-size light-conducting plate can not be used, bring inconvenience to the user.
The technical problems to be solved in the utility model is to provide that a kind of size is unrestricted, the simple light guide plate of production and processing.
The utility model content
For the problem that solves that above-mentioned prior art is restricted to product size, processing is inconvenient etc., the utility model adopts following technical scheme:
The utility model provides a kind of light guide plate, comprise light guide plate main body, be provided with several LED lamps at described light guide plate main body side, be provided with the major network point in described light guide plate main body centre position, described major network point comprises some row's round dots, the size of described round dot is increasing successively away from LED lamp direction, at described light guide plate main body side, near LED lamp position, is provided with two row's sizes irregular auxiliary site of differing, and described auxiliary site is rounded, the regular polygon shape.
The beneficial effects of the utility model are: adopt the mode of modifying site to improve the situation of light and shade inequality, and the effect highly significant, simple to operate, cost is low.
The accompanying drawing explanation
The structural representation that Fig. 1 is a kind of embodiment in the utility model.
Embodiment
Describe preferred embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Refer to Fig. 1, a kind of light guide plate, comprise light guide plate main body 1, be provided with several LED lamps 2 at described light guide plate main body 1 side, be provided with major network point 3 in described light guide plate main body 1 centre position, described major network point 3 comprises some row's round dots, the size of described round dot is increasing successively away from LED lamp 2 directions, be provided with two row's sizes irregular auxiliary site 4 of differing at described light guide plate main body 1 side near LED lamp 2 positions, described auxiliary site 4 is rounded, the regular polygon shape, increase by modification the phenomenon that light and shade inequality on light guide plate main body 1 is improved in auxiliary site 4, directly adopt serigraphy to get final product, very convenient and successful, and traditional improvement mode is to increase Tp, this mode is by the Mould Machining realization that is shaped, die cost is high, and can only be used on undersized light guide plate, use very limited, use inconvenient.
Above-described embodiment and a graphic and non-limiting realification or modification, all should be considered as not breaking away from patent category of the present utility model.
