Description
Technical field
The present invention relates to a kind of light guide plate, especially relate to a kind of MS light guide plate with bright dipping micro-prism structure.
Background technology
Light guide plate, for guiding light transmission direction, the pointolite that the incident side by light guide plate enters or line source are penetrated by the exiting surface of light guide plate and then are become area source after the scattering and reflection of light guide plate.Furthermore, whether this area source has enough brightness and the whether luminous structural design evenly then depending on light guide plate completely.
In traditional light guide plate design, especially in plate shaped light guide plate: (1) has one side to arrange the design of U-shaped groove one side printing light guide ink site, the face at U-lag place is allowed to be exiting surface, allow the face at place, light guide ink site be bottom surface, make it to destroy the total reflection of light thus light can be penetrated from exiting surface in a large number; (2) there is one side that the design of vee-cut one side printing light guide ink site is set, allow the face at V-shaped groove place be exiting surface, allow the face at place, light guide ink site be bottom surface, make it to destroy the total reflection of light thus light can be penetrated from exiting surface in a large number.By the cooperation of U-lag and ink site, or the transmission direction of the cooperation of V-shaped groove and ink site to light guides, and then sends the enough and light be evenly distributed of brightness at the exiting surface of light guide plate.
In above-mentioned design, because V-shaped groove itself has a tip, so more easily guide the transmission of light compared to U-lag V-shaped groove, so add a small amount of guide-lighting particle can meet certain standard.But be no matter U-lag design or V-shaped groove design: first, they all to need in printing light guide ink site, bottom surface the enough and uniform feature of luminescence to the brightness meeting light guide plate.And the ink printing of light guide plate itself is not easily management and control in process of production, add and also will to match the incompatible guiding completed light with the U-lag of design or V-shaped groove, therefore its production process requires harsh, and complicated.Simultaneously from another aspect, due to the more complicated of typography own, so need the equipment a lot (such as printing press, infrared drying stove etc.) dropped into, input cost is higher, and a large amount of ink material that uses also easily produces waste gas in printing process, pollute.
Meanwhile, tradition also has a kind of light guide plate to be design like this: (1) one side arranges U-lag and has smoothness on one surface, and is added with a large amount of guide-lighting particle, allows the face at U-lag place be exiting surface; (2) simultaneously arrange V-shaped groove to have smoothness on one surface, and be added with a small amount of guide-lighting particle, allow the face at V-shaped groove place be exiting surface.Guided by U-lag and the cooperation of guide-lighting particle or the transmission direction of cooperation to light of V-shaped groove and guide-lighting particle, and then make light extraction efficiency and the homogeneity of guarantee light guide plate.This two kinds of light guide plate design above-mentioned does not just need printing-ink site, solves the problem that typography not easily management and control, equipment investment are too high, easily pollute.But the guide-lighting particle components preparation process complicated difficult control added in these two kinds of light guide plate designs, R&D costs are high, and use cost is also high.Although market there is the guide-lighting particle that some compositions are simply common, its effect that light guide plate can be reached is unsatisfactory.
Summary of the invention
Object of the present invention is exactly to solve the problem, a kind of MS light guide plate with bright dipping micro-prism structure is provided, be intended to both to adopt typography to carry out the printing of light guide ink site, also extra guide-lighting particle need not be added, just be provided with the light guide effect also more excellent than the above two, brightness is high, luminescence is more even.
To achieve these goals, the present invention adopts following technical scheme: a kind of MS light guide plate, comprises light-passing board, and described light-passing board comprises exiting surface and bottom surface, and described light-passing board is made up of MS material;
